Phishing emails are an attempt to steal your identity.

Identity theft information is contained on three pages:

  1. Identity Theft: obtaining information by deceit
  2. Phone Fraud: scamming by phone
  3. Phishing: email scams

This page will help teach you how to prevent yourself from becoming a victim.

The information was written with computers in mind, but these warnings also apply to smart phones and tablets.


When I received an email with the following address:

From: Shoppers Drug Mart <[email protected]>.

I knew it was a phishing attempt because it claimed to be coming from Shopper's Drug Mart and would use a domain-based email address, not a Gmail address.

It is likely that the Toni's Gmail account was hacked, probably a result of poor password hygiene.

I marked the mail as spam using the tools in my email program without clicking on any links or investigating further (too risky).

The following is a screen capture of another email, supposedly from Microsoft:

Phishing email.

  • The email is from “[email protected]” rather than a microsoft.com-based email address.
  • Clicking the “Update Your Settings” would send you to another non-Microsoft location.

Typically, the destination page would ask for your login information, immediately compromising your Microsoft account.

Phishing: Obtaining Information by Deceit

Phishing is a form of spam intended to obtain financial and personal information by deceit.

Phishing is sending emails or other electronic communications to fraudulently or unlawfully induce recipients to reveal personal or sensitive information, such as passwords, dates of birth, Social Security Numbers, passport numbers, credit card information, financial information, or other sensitive information, or to gain access to accounts or records, exfiltration of documents or other sensitive information, payment and/or financial benefit.
— Microsoft
  • It takes advantage of vulnerabilities in some browsers and email programs but depends even more upon people's ignorance.
  • The intent is to steal your on-line identity — a crime commonly referred to as identity theft.
  • More often than not the payment is in the form of untraceable cryptocurrencies or by purchasing gift cards and sending the code to the fraudsters.
  • The information gained will be used to gain unauthorized access to your existing accounts or to establish new ones. Crimes may be committed in your name and your reputation may be destroyed.

Phone and email scams have a lot in common.

There are a few basic psychological tricks that phishing attacks and phone scams attempt to use against us — and the pandemic has provided the perfect environment for them.
BBC Future
The magic sauce, as it were, is in the way phishing attacks are branded. Attackers are doing their homework by researching targets on social media, message boards, media reports, and other online sources to find hyperspecific ways to manipulate human nature and emotions. They use people's fears, their sense of urgency or curiosity, or their need for reward, validation, or an entertaining distraction.

[M]any scams are highly orchestrated endeavors, made up of lots of psychological ploys that might just hit an otherwise intelligent individual at a personal low point in time.

Report Identity Theft

If you have been a victim of identity theft (or suspect you have), contact the police to report identity theft.

Don't let embarrassment keep you from talking to the authorities. If you were the only victim, identity theft would not be a growing problem.

The sooner you report the potential identity theft, the sooner you can begin to resolve the issue.

While local police may be unable to do much with an international-based crime, the report will help to establish credibility when dealing with your bank and other institutions when you try to repair the damage.

Email Scams

A staggering 91% of cybercrime starts with email.
CSO

Fraudulent emails are called phishing emails. When the email is personalized to target an individual using specific accurate information, it is called spear phishing.

“Callback phishing” uses email with a fake invoice or other urgent item to induce the recipient to call a phone number.

Callback phishing typically involves an email, a phone call and a fake subscription/invoice notice. In recent months, hackers have impersonated businesses in order to dupe victims into making phone calls that lead to the download of malware.

Stop and Think Before Acting

The phishing email is designed to get you to act impulsively, before you have a chance to think.

Remember to Stop. Think. Connect. — Pause before you click or connect.

How to Respond

How to protect against scam emails (from Acronis):
  • Do not panic. Do not get scared by the crooks. They do not know you, nor do they have access to your computer. It is a classic scare technique. Try to ignore it, even if it sounds disturbing.
  • Do not pay. Once you've paid money, you will not get it back. Instead, you might be attacked more frequently since you've shown the attacker that you are a profitable target.
  • Use strong passwords. Use unique strong passwords for different services. If possible, enable multi-factor authentication in order to increase security. A password manager can help you remember all these different passwords.
  • Awareness-training programs. As an organization, you should implement an awareness-training program for your employees. Also, make sure that your employees know how to report such scam emails to your IT department.
  • Update all relevant systems. Ensure that all your systems are up-to-date and that you are using a comprehensive security solution that can automatically protect you from the newest cyberattacks.

Sextortion

One disturbing phishing attack is a blackmail email (called sextortion) claiming to have hacked your computer demanding payment to keep your secrets. It can also result from someone finding out about outside activities.

The extortionist then seeks out your contacts and other vulnerabilities via your social media accounts. Knowing who is closest to you is then used by the blackmailer to threaten to expose your activities to your friends, family and co-workers.

Teens a Target

Too often children are targeted by online predators pretending to be someone of similar age interested in friendship and more. Once the predator gains their trust, they try to get the teen to send compromising photos which they then threaten to post online or reveal to their friends and family.

Threats may be used to further gain additional photos or even to meet the “friend” in person.

[Stephen Sauer, the director of Cybertip.ca] said oftentimes children are specifically targeted. Organized crime rings based overseas pose as young women on social media platforms that teenagers use such as Snapchat and Instagram.

 

They convince them to send sexually explicit images or videos and then immediately threaten to share the content if the children don't provide them with money or sometimes more images.
Victoria Times Colonist

This sort of blackmail can result in suicide when the youth feels there no one to turn to.

This is why it is so important for parents to monitor their children's online activities, especially on social media.

Blackmailed Online?

If you are being blackmailed online, paying the scammer will not resolve the issue. You'll need expert help.

Dennis Faas is an experienced systems administrator and IT technical analyst specializing in cyper crimes (sextortion, blackmail, tech support scams).

Facebook Blackmail Popular

While there are many avenues to obtain phishing information and use it against someone, Facebook is particularly attractive to blackmailers:

With…many people actively using Facebook, it makes it easy for Facebook sextortion scammers to find information about you, including: a list of your family members, friends, where you live, where you work, etc — all without having to spend time looking it up elsewhere, or having to pay a third-party website for the information. This is what makes Facebook blackmail so popular.
Dennis Faas

Read Dennis' article fully before contacting Dennis. It explains what he does and explains the sorts of activities that result in blackmail:

See Blackmailed Online? for a solution if you're a victim.

“Your Computer Hacked”

Claims that your computer has been hacked is a common approach for online blackmail attempts. Any messages using the threat of exposing your porn habits should be immediately deleted. These are a phishing email on a fishing expedition. Don't fall for it.

Sample Sextortion Email

Here's some of the text from a sextortion email quoting the email address as the account:

I have bad news for you. I hacked into your operating system and obtained full access to your account. After that, I made a full backup of your disk (I have all your address book, view site history, all files, phone numbers and addresses of all your contacts).

 

I took a screenshot of the intimate website where you are satisfied (Do you understand what I mean?). After that, I made a video of your pleasure (using the camera of your device). It turned out beautiful! I firmly believe that you would not want to show these photos to your parents, friends or colleagues. I think 300 € is a very small sum for my silence.

 

P.S. I guarantee that I will not disturb you after the payment because you are not my only victim. It's a code of honor for hackers.

Criminals have no code of honour. The other statements are just as false.

The goal was to rattle the recipient into sending 300 €. Paying any ransom, just like paying blackmail, is never recommended.

Passwords as “Evidence”

Often the email will include a password as the proof of their access. These passwords were probably obtained from a security breach.

[I]t is often the case that the scammers have no such evidence of the user's activity; they are just bluffing to get the user to pay the ransom. A password can be bought for a few dollars on the dark web, and scammers are often clever in how they present the little information they have.
Check Point blog

Be sure to change all your passwords after learning about any breach that involves any online service you use.

Unfortunately, in the modern age, data breaches are common and massive sets of passwords make their way to the criminal corners of the Internet. Scammers likely obtained such a list for the express purpose of including a kernel of truth in an otherwise boilerplate mass email.
EFF

Have You Been Hacked? is a Mozilla service that can check to see if your email has been involved in a security breach.

Tighten Your Security

If you have decent up-to-date computer security software, have changed the default passwords on your router and use good password hygiene it is highly unlikely that you've been hacked.

If the language is quite generic and without details, I suggest you ignore the threats. However, you should do a security audit to ensure your system is secure rather than paying a scam artist.

Spear Phishing

“Spear” phishing is harder to detect. It uses personal information found online such as details you shared on social media or was culled from a data breach then sold on the Dark Web.

The email may appear to come from someone you can trust, but it is a scammer looking to steal from you.

The spear phisher thrives on familiarity. He knows your name, your email address, and at least a little about you. The salutation on the email message is likely to be personalized: "Hi Bob" instead of "Dear Sir." The email may make reference to a "mutual friend." Or to a recent online purchase you've made. Because the email seems to come from someone you know, you may be less vigilant and give them the information they ask for. And when it's a company you know asking for urgent action, you may be tempted to act before thinking.

These messages often have short deadlines or are made to appear urgent in their nature. The more you analyze the message, the more likely you're able to see through the deception.

Looks Can Be Deceiving

Phishing often involves using a well-known brand name to convince you that you're seeing information from a legitimate source (a transfer of trust). You're not.

In a brand phishing attack, criminals try to imitate the official website of a well-known brand by using a similar domain name or URL and web-page design to the genuine site. The link to the fake website can be sent to targeted individuals by email or text message, a user can be redirected during web browsing, or it may be triggered from a fraudulent mobile application. The fake website often contains a form intended to steal users' credentials, payment details or other personal information.
Check Point blog

The Check Point blog also noted the most imitated sites in the second quarter of 2021:

  • Microsoft(related to 45% of all brand phishing attempts globally)
  • DHL (26%)
  • Amazon (11%)
  • Bestbuy (4%)
  • Google (3%)
  • LinkedIn (3%)
  • Dropbox (1%)
  • Chase (1%)
  • Apple (1%)
  • Paypal (0.5%)

Some Resources

These are some excellent resources on dealing with phishing attempts:

I use AntispamSniper, an excellent third-party antispam tool, with The Bat!. They have some excellent suggestions on identifying and avoiding phishing attacks.

Identity Theft is a Long-Term Problem

If you are the victim of identity theft, you can expect to fight to regain your credit rating for years — over and over again.

Victims report that it takes months or years to regain their credit rating, only to find that a new report forces them to start all over again.

Keep Paper Files

While electronic data can quickly get you into trouble, financial institutions want physical (on paper) evidence that you're not responsible.

How Phishing Works

Going on a Phishing Expedition

Becoming a victim is easier than you might think. Let's have a look at the process from the perpetrator's point of view.

Remember, YOU are the intended victim of this trap.

Step One: Create a Fake Website

The first step is to set up a look-alike site that closely resembles a site that your victims are already using or could be using. The company's logo and other trademarked images are used to convey authenticity. (See the section on using transfer of trust.)

Proprietary Images Can be Hijacked

If a site invites you to use your email and password to log into Yahoo!, Gmail, Windows Live, AOL or other email account, DON'T!

The “Google Docs” image (shown beside this text) was captured from a fake website several years ago.

A similar layout was embedded into an email (one of the reasons you DON'T want to allow your email program to automatically download images).

The technologies employed in phishing attempts has improved a great deal since then.

Don't Follow Links in Emails

Don't follow any link in either emails or websites to log into accounts on sites like Yahoo!, Gmail, Windows Live, AOL, etc. The email may employ fake links to misdirect you into providing your login details on a bogus site.

Instead, use the address included in a legitimate source like a paper invoice or account statement.

Any phishing message could exploit a bank (most have been targeted), Google Docs, e-Bay, PayPal or any site where you conduct business using a credit card or is protected with a user name (usually your email address) plus a password. Only your password is unique in this combination.

Don't Use Facebook or Google Logins for Third-party Sites

You should NEVER use single sign-on options (e.g., signing in with your Facebook or Google account for third-party sites). While convenient, it creates a single point of failure for ALL your accounts in the case of a security breach.

It can also provide third-party websites with a great deal of information about you, including your interactions on that Facebook or Google login account.

Use a Password Manager

Instead, use a password program like LastPass to generate unique passwords and to manage all your account logins.

Fake Links Cull Account Login Details

When you click on these links and enter the requested login information, you giving thieves access to your real account(s).

They probably will change the password to lock you out of your own account to assume ownership.

Your email account is a key recovery mechanism for your other accounts. The scammer would soon control your social media and other accounts linked to it.

All they have to do is click on the “forgot password” link on the various sites, then check your email account for the recovery information or links. Any warnings from those sites would be sent to an email account controlled by the hackers, not you.

Step Two: Send Out an Email

Next, send an email message to thousands of potential victims (like you) indicating that there is a problem with their account.

Most such messages indicate that you must act quickly or your account will be closed. The message requests personal information including your user name and password (bank PIN if your bank account is the target).

They don't want you taking time to think or to contact the actual company where the account is located, do they?

Legitimate businesses will never ask for personal or account information via email or phone calls placed by that business.

An Example

This message was sent to Islandnet.com customers a number of years ago:

We would like to inform you that we are currently carrying out scheduled maintenance and upgrade of our account service and as a result of this your accounts have to be upgraded.

 

We are sorry for any inconvenience caused.

 

To maintain your account you must reply to this email immediately and enter the information below:

 

User name:

 

Password:

 

Failure to do this within 72 hours will immediately render your account deactivated from our database.

The headers show that the message did NOT come from Islandnet:

From [email protected] Tue, 17Aug 2010 4:33:41 -0700 (PDT)
From: "Islandnet.com::Index" <[email protected]>
Return-path: <[email protected]>
Envelope-to: [email protected]

Islandnet.com would never send out such a message and would never use a yahoo-based email address like [email protected].

How to Read Message Headers

Scammers Getting Smarter

You can't count on identifying spam by the email sender's address. Scammers often know how to forge headers to make it appear to come from a legitimate company.

Recently I've noticed that spam with the same message seems to come from a different email address every time (probably the same scammer using stolen addresses).

According to Symantec's 2015 Website Security Threat Report Part I, it costs as little as $0.50 to $10 per 1,000 stolen email addresses on the black market — a testimony as to the poor quality passwords many folks use and how easy it is to obtain them.

HTML Email Hides Details

One of the dangers of "enhanced" or HTML email is that stuff can be hidden. See How to unmask fake links.

Firefox security features help you avoid problems with invalid or insecure sites.

Other browsers may have these features, but Firefox is the only major independent browser and Mozilla is committed to personal privacy.

Step Three: Collect the Information

The victim (that's you) clicks on the link and finds themselves on what they believe to be the correct site.

Remember, the perpetrator has created the site to look like the original, so they enter their user name (email address) and password.

Of course, this information is not going where you think it is — you're sending it directly to thieves.

Step Four: Assume Your Identity

Taking your electronic identity (which you've just provided to them on the phishing site), the thieves go to the actual site (such as your bank's website) then log into your account.

The information obtained in this manner is then used to either obtain funds from your account or to set up credit in your name.

The example above is designed to lure you into providing account information and/or to visit a bogus website where you'll enter that information.

An “URGENT Help Request”

A message can also be designed to get you to send money via Western Union or some other method.

This sort of email will seem to come from a “friend” or “family member” that needs money to help them pay their hotel bill or get home because they've suffered some sort of accident or are the victim of a crime.

The sender hopes you reply with your financial details so they can collect the funds themselves.

Stop and Examine the Email

Their goal is to get you to respond quickly before you can think too hard about the claims in the message. Beware of these signals:

  • The sender indicates they are “out of contact” but in dire need.
  • Watch for any attempt to get your user name and password such as a response form embedded in the email message itself. Would the sender be able to generate such a form, even if it were legitimate?
  • Attached files are suspect (most contain scripts that will infect your computer).
  • Altered or unusual links in the body of the message or its attachments.
  • The presence of official looking logos attached to the message (most companies now use images hosted on their server).

The details in the email are usually general in nature. Some information may be accurate but the scammer doesn't know you as well as the real person does.

How Did They Manage to Contact You?

Ask yourself how the sender was able to email you when they have no cash, credit cards or cell phone?

  • A genuine victim could have resolved their issues with a call to the credit card company.
  • The hotel would have obtained a copy of a guest's credit card when the reservation was made (and verified it when the person checked in).
  • The airline could re-issue a lost or stolen ticket.
  • Emergency passports can be re-issued by embassies everywhere.

Tighten Passwords

The real owner of the email address needs to let people know they're okay and to change their password to something more secure (and probably change their security habits).

Fake Emails Getting Better

Recent phishing email scams are harder to detect. Scammers are improving their techniques as well as their grammar. They employ spear phishing techniques to make the message more believable.

[P]hishing messages only seem to be getting savvier and more authentic-looking, fooling even seasoned experts. Gone are the days when obvious misspellings and grammatical errors provide a dead giveaway that shenanigans are at play.
Trustwave Blog

Return to top

One of the methods commonly used to scam people are fake links in email messages.

Fake links drive unsuspecting traffic to websites that:

  • generate revenue for them via pay-per-click ads or similar revenue generators; or
  • pretend to be a legitimate site like a bank (in order to steal account information); or
  • infect their computers with malware (turning their computer into part of a botnet that attacks legitimate sites or attempts to infect other computers).

Decent security software and detection provided by web browsers like Firefox can help prevent such attacks, but it is best not to click on these links in the first place.

Where Does That Link Go?

Would you click on links like the following?

Of course not.

Those looking to steal your identity aren't going to unmask themselves. They tell you the link points to something that takes advantage of your curiosity or greed.

You can't trust the linked text to tell you where the links actually go because it is ignored by your browser.

Links Have Two Components

Hyperlinks on a website (and in an email) have at least two components:

  1. the linked text (what you see highlighted in the link); and
  2. the hyperlink (the actual address where you are being sent).

Only the hyperlink itself (the hidden part) determines where the link sends you.

Just as placing a Mercedes licence holder onto a Ford doesn't turn it into a Mercedes, a misleading description doesn't change the link's destination.

Take a look at the following link (a new window opens):

Hint: it doesn't take you to the Bank of America's site, but to another (but safe) site.

Using the Status Bar

If you hover over the link and look in the status bar at the bottom of the program (some browsers show the hyperlink address in a small box above or below the link itself) you can tell the destination without clicking the link (and potentially getting yourself into trouble).

Just because the linked text says it is pointing towards a particular address doesn't mean that is the real destination.

Learning More of the Mechanics

If you are interested in the mechanics of this process, have a look at Cut 'N Paste HTML Editing. It gives some simple HTML lessons and demonstrates how HTML links work.

Short Links (URLs)

Shortened links (web addresses or URLs) are common in Twitter messages because 140 characters doesn't allow for long complex links.

These are also useful in emails where very long and complex links can be broken when the line is wrapped by your email program.

Services like TinyURL and Bitly hide the destination address.

Unmasking Shortened URLs

You can unmask the destination of these links before visiting the site. Paste the address into your browser's address bar with the changes noted below, then hit enter:

You're taken to TinyURL or Bitly with information showing about the true (full) destination for the shortened link. In these examples, all shortened links point back to this page.

Other Link Shorteners

If you're unable to determine the destination, I recommend using Redirect Tracker to check any short or affiliate URL (bit.ly, goo.gl, etc.) to see where it goes.

Phishing Emails

Shortened URLs are seldom needed in an email except where the length of a complex address wraps in the email window, potentially causing the link to break.

Phishing email emails commonly use shortened links to obfuscate the destination.

Emails containing the promise of a financial reward (“click bait” messages) are dangerous. I strongly recommend deleting such messages.

In most cases, clicking on these will simply bring you grief.

An Example

I received a suspicious email (supposedly from “Costco”) with a shortened link. Redirect Tracker revealed that the unmasked destination address was being redirected twice from the obfuscated address:

The destination of an ow.ly link reveals it is being redirected twice

This is not a good sign, especially since “zharerewards” is an obvious misspelling of sharerewards.

Other Issues

Shortened URLs have security and other issues.

How Can a Fake Site Exist?

First of all, people that set these fake sites up wish to remain anonymous. They are breaking the law and don't want you (or the police) to be able to find them after they steal your identity.

Short-Term Links

The provided links are only up for a short time before they are removed by the owners of the site affected or by the legal authorities.

Forged links often point to a site in an educational institution where passwords and access are easy to come by.

By their very nature, universities house a lot of smart and curious people. Smart as they are, too many don't view the issue of security as their problem.

Because of lax attitudes, many could suffer significant financial setbacks.

Delete Attached Forms

More recent phishing attempts have provided an attachment to their messages which, when opened, replace the fake site with a form which accomplishes the same nefarious purpose — to get your information using deception.

Don't be fooled. An unexpected attached form (or PDF or Zip file) is likely an attempt at identity theft. Even .DOCX and other Microsoft Office documents can be dangerous.

Configuring Your Software to Protect You

Whatever choices you make with your software, you'll want to take advantage of some advanced (and often hidden) features:

  • Ensure that you can see the hints when your mouse hovers over a link or other hot spots on your browser.
  • Use stronger passwords. There are complex online password generators as well as software to help remember more complex passwords. I strongly recommend LastPass password manager.
  • Only shop on encrypted websites — those prefixed with https:// and displaying a padlock symbol in the address bar. Unencrypted sites are more vulnerable to being hacked.
  • Learn how to view the headers in an email message.
  • Know the signs of a risky message (phone and phishing scams have a lot in common).
  • Ensure your security software is current and updated daily.
  • Windows users are more vulnerable and should ensure that all critical Windows Updates are installed, including the latest service pack.
  • Mac and Linux users also need to be vigilant in updating. While infections are not as common, they are becoming more frequent.
  • Ensure your browser and email software are current and updated.
  • Stop using and uninstall software that is no longer actively supported or maintained.

Advanced features are often hidden to provide for a cleaner, simpler look. Microsoft's hiding of known file extensions is one example.

Remember, software vendors don't have to pay to clean up problems caused by the shortcomings in their products or within optional downloads installed at the same time as their own product.

If you need help determining how to configure your software and security protection, contact someone knowledgeable. Be careful when selecting your “expert” helper (especially if they call you). Remember, you're putting your trust in this person.

I provide these services, but only in Greater Victoria (located on the west coast of Canada).

Get Help From Your ISP

Use whatever tools your ISP makes available to identify potential spam, phishing and other problematic email messages. Check your ISP's help or support website or call their help line.

I strongly recommend hosting with Islandhosting.com.

This site hosted by
Check out Islandhosting.com

They specialize in website hosting and can provide personal support when you need it. Their friendly, knowledgeable staff can deal with most email programs and services.

Unlike some major ISPs, you're dealing with a real person that is knowledgable, not someone overseas with a script in front of them.

Return to top

Using Transfer of Trust

A successful phishing scheme, like any con, depends upon gaining your trust.

They'll use your trust of your financial institution, a major vendor (e.g., Microsoft or Apple) or other authority (CRA, CRTC, FBI, phone company, etc.).

If you believe they are who they say they pretend to be, then you'll be more likely to follow their instructions without questioning anything.

Your “trust” in the caller, web page or link is only because it appears to be from someone you know and trust.

The Internet Can Be Exploited

The original Internet was used only by scientists exchanging data. There was no need for high security. Trust was implied.

But this has changed. The Web is now used for e-commerce, personal transactions, banking, socializing and more.

Browsers and modern enhanced email messages can be exploited, particularly if you don't understand HTML markup. Without that knowledge you can't protect yourself.

Preventing Successful Phishing

There are a number of things that you can use to avoid being the victim of this type of attack:

  • Be wary of any threats to close your account especially emailed notices.
  • Requests for account information or passwords are NEVER legitimate.
  • Be wary when using public computers. Your passwords, accounts and personal information can be retained by the browser's cache for later retrieval by anyone with access to that computer.
  • Do not use open or untrusted secured wireless networks such as those at coffee shops and other public networks. Someone can be "listening in" on your traffic.
  • Do not trust information emailed to you including any links to sites.
  • Do not trust information on an unknown website.
  • Keyloggers can capture private information on any computer.

Always use trusted sources to obtain the telephone number or website address to contact any site requiring personal information or a password.

Google is not necessarily that trusted source. Many “sponsored” links are capturing key searchable words (called key words in SEO), not providing expertise.

 

Anti-Phishing Tools

These tools and information sites will help you to learn more about phishing and provide you with tools to verify suspect websites and files.

I urge caution when using these tools. Be sure you understand the terminology as well as the risks.

Suspicious Websites

Check to see if a site has been flagged for phishing:

  • PhishTank is a collaborative clearing house for data and information about phishing on the Internet.
  • urlQuery.net is a service for detecting and analyzing web-based malware.
  • CSI: ACE Insight allows you to check for malicious sites.

Check the site's information and/or disclaimer pages so you understand the capabilities and shortcomings of the service. The following is from urlQuery's“ About” page but can be applied to most such services:

Currently no service or security solution provides 100% detection of malicious content. The data provided is to help give a second opinion and should not be taken as fact. As with other sandbox technologies it can be detected which can skew or make the results inaccurate. Other issues might include browser incompatibilities or settings/configurations within the browser.

Cryptocurrency Scams

cryptocurrencies are electronically generated pseudo currencies such as BitCoin. They have become very popular because they allow for anonymous transactions and because of the extraordinary growth in their value.

As a result there are now multiple cryptocurrencies and they have become a common element in scams, both in their reward offerings and in the method of extracting payment from unsuspecting victims.

Kaspersky says that fake exchanges, fake mining hardware and wallet phishing are the most popular crypto scams of the year, many of which it said have a higher-than-usual level of detail.

 

People investing or interested in this area are often more tech-savvy than the average user. Therefore, the cybercrooks make their techniques more complex in order to get data and money from these people
TechRepublic

Don't fall for emailed offers of cryptrocurrencies. Think before acting. If it's seems too good to be true, it's probably a scam.

Only use apps from trusted sources.

Cryptocurrency apps that have to be downloaded from outside the official iOS, Android or other app store are generally dangerous, especially if the link is provided in an email from an unknown source.

Suspicious Files

Be cautious when checking out suspicious files. In most cases you're safer simply deleting the email along with the unopened suspect file unless you were expecting it from a trusted source.

Malicious Microsoft Office attachments are more common than malicious batch scripts and PowerShell scripts.
Tech Republic

Security software is a must. Ensure that your security software is current. Scan new downloads before installing or running it.

Delete Attached Forms

If your security program detects a problem with an attachment, you'd best delete it rather than having the program treat it even if it is an essential file sent from a trusted computer.

More recent phishing attempts have provided an attachment to their messages which, when opened, replace the fake site with a form which accomplishes the same nefarious purpose — to get your information using deception. Don't be fooled. An unexpected attached form (or PDF or Zip file) is likely an attempt at identity theft. Even .DOCX and other Microsoft Office documents can be dangerous.

You're best to discard it rather than risk infecting your own computer by opening the attachment. Instead, print out a copy of the file on the original computer while disconnected from the Internet. The original computer needs to have a full security scan with a current and updated software.

Beware of Hidden File Types

Windows hides “known” file extensions by default. While they are known to Windows, many users don't understand the risks they can pose such as what sorts of files can infect your computer.

Several file types (including .EXE, .SCR, .COM and .BAT) are not safe to open, especially when received as an email attachment.

You should change your settings to unhide known file types.

Microsoft Office files, such as those with MS Word's .DOC and .DOCX extensions, can also carry dangerous scripts.

Checking Unknown Files

If you're unsure if a file is safe, you're better off deleting it than checking it out yourself. If you need the file, use one of these resources to check it out before opening it.

  • ZoneAlarm Extreme's Threat Emulation opens unknown files in a virtual sandbox to examine what they do before you risk your computer's security.
  • CSI: ACE Insight allows you to upload suspect files you received as attachments.
