Chrome users panic as new scam spreads

During the previous quarter, fake Chrome notifications urging users to dial a tech support number have grown dramatically. Research reveals that this tech support scam could possibly use an Application Programming Interface (API) to freeze the browser, convincing the user to get in touch with the support line and share their credit card details.

The End Game

The scam works by displaying an error message indicating a bogus security breach incident that renders a browser unusable. These scammers capitalize on the fact that a serious crash can’t be solved by simply closing the site, thereby sending the users into a panic. This encourages them to dial the number listed on the warning message.

On the other end of the line, the scammers would pose as Microsoft or Apple representatives to convince users into surrendering their credit card details to repair a non-existing security issue. The scams are generally carried out through legitimate sites or malicious ads that have been hacked.

The Ingenious Process

This new scam operates against Chrome by corrupting the window.navigator.msSaveOrOpenBlob programming interface, which basically uses it as a form of distraction. The hackers manipulate the browser and forces it to save a random document on a disk repeatedly at super fast intervals that are impossible to notice. After five to 10 seconds, Chrome will be completely unresponsive.

The Easy Fix

To recover, Windows users simply have to open Windows Task Manager (press ctrl + shift + esc keys) and stop the process there. On the other hand, macOS users just need to wait until a system message prompts them to close the unresponsive Chrome tab. Typically, the latter is a more appealing option since users would have the freedom to close only the corrupted page. Manually closing the whole browser means possibly losing unsaved files in any open Windows.

Enlist IT help when installing CPU updates

January 24, 2018 admin Security 2018january24security_c, chrome, edge, firefox, flaw, ie, Intel, linux, macos, meltdown, safari, security, spectre, vulnerability, windows

When it comes to security updates, time is usually of the essence. The longer you wait to install a fix from a vendor, the higher the risk of being compromised. But in the cases of the Meltdown and Spectre flaws, you might be better off waiting until a more reliable patch is released. Let’s review what’s going on and what the best course of action currently is.

Unsecured data storage

Spectre and Meltdown are the names given to two hardware flaws that allow hackers to see any piece of information stored on your computer. Although slightly different in execution, both take advantage of a hardware feature that computer chips use to access and store private information. For the last 20 years, security experts believed this information could not be stolen or spied on by malicious software, but that assumption was proven false on January 3, 2018.

Now that the Spectre and Meltdown vulnerabilities are public information, hackers can use them to create programs that steal passwords, social security numbers, credit card numbers, and anything else you type into your computer.

Because these problems are hardware-based, none of the updates will be able to secure the vulnerable storage; they’ll simply prevent your computer from storing anything in it. Currently, there are patches for:

Operating systems (Windows, macOS, and Linux)
Web browsers (Chrome, Firefox, Safari, Edge, and IE)
Chip firmware (low-level programs installed on the processor itself)

If you’re using an Apple computer, these updates are relatively easy to install. If you’re using a Windows or Linux-based computer, these patches may cause your machine to freeze, reboot unexpectedly, or significantly slow down.

Why should I wait to install the updates?

Intel, one of the chipmakers responsible for the Spectre and Meltdown flaws, has provided contradictory recommendations on more than one occasion. As recently as January 18, Intel recommended waiting for an updated patch, but in the same announcement also recommended “consumers to keep systems up-to-date.”

Experts believe detecting an attack that is based on one of these flaws will be relatively easy and represent an alternative to installing updates that could render your computer unusable.

What should I do?

IT support experts will be able to quickly and easily assess what is the best option for your computers. For example, our team can determine whether or not your hardware will conflict with the current patches, and either install them or set up a detection strategy that will help you mitigate the risks without ruining your computer.

Beware of what you save in web browsers

January 9, 2018 admin Security 2018january9security_c, auto-fill, chrome, cybersecurity, firefox, Passwords, privacy, safari, web browsers

Passwords are a double-edged sword. If you make them too simple, they’ll be easy to guess; if you make them too complex, they’ll be impossible to remember. One solution is to create an uncrackable password and save it to your browser. Unfortunately, recent research suggests that tactic could drastically reduce your privacy.

Why auto-fill passwords are so dangerous

In 2015, the average internet user had 90 online accounts, a number that has undoubtedly grown since then. This has forced users to create dozens of passwords, sometimes because they want to practice healthy security habits and other times because the platforms they’re using have different password requirements.

Web browsers and password manager applications addressed this account overload by allowing usernames and passwords to be automatically entered into a web form, eliminating the need for users to hunt down the right credentials before logging in.

The process of tricking a browser or password manager into giving up this saved information is incredibly simple. All it takes is an invisible form placed on a compromised webpage to collect users’ login information without them knowing.

Using auto-fill to track users

Stealing passwords with this strategy has been a tug-of-war between hackers and security professionals for over a decade. However, it has recently come to light that digital marketers are also using this tactic to track users.

Two groups, AdThink and OnAudience, have been placing these invisible login forms on websites as a way to track which sites users visit. These marketers made no attempts to steal passwords, but security professionals said it wouldn’t have been hard to accomplish. AdThink and OnAudience simply tracked people based on the usernames in hidden auto-fill forms and sold that information to advertisers.

One simple security tip for today

Turn off auto-fill in your web browser. It’s quick, easy, and will go to great lengths to improve your account security.

If you use Chrome – Open the Settings window, click Advanced, and select the appropriate settings under Manage Passwords
If you use Firefox – Open the Options window, click Privacy, and under the History heading select “Firefox will: Use custom settings for history.” In the new window, disable “Remember search and form history.”
If you use Safari – Open the Preferences window, select the Auto-fill tab, and turn off all the features related to usernames and passwords.

This is just one small thing you can do to keep your accounts and the information they contain safe. For managed, 24×7 cybersecurity assistance that goes far beyond protecting your privacy, call us today.

Hackers use browsers to get credit card info

January 27, 2017 admin Security 2017january27_security_c, chrome, credit card theft, hackers, safari, security

Does filling in web forms sap all your browsing energy? Do you find it especially taxing to shop or register online using a mobile device? Google’s Chrome alleviated this dilemma when it introduced the Autofill feature in 2011, which made filling in forms much faster and making credit card purchases online more convenient. Unfortunately, it didn’t take that long for cyberthieves to find a way to take advantage.

How do they do it?

By concealing other fields in a sign-up form, users are tricked into thinking they only have to fill out a few fields. The trickery at work is that upon auto-sign up, other fields, which could include your billing address, phone number, credit card number, cvv (the 3-digit code used to validate credit card transactions), and other sensitive information, are auto-filled with the user none the wiser.

This sinister trick is nothing new, but since there hasn’t been any countermeasure since it was first discovered, the threat it poses is worth emphasizing. Finnish whitehat hacker Viljami Kuosmanen recently brought to light how users of Chrome and Safari are particularly vulnerable, and he even came up with a demonstration of how this phishing technique is perpetrated. The technique is so sneaky, it’s enough to make one give up online shopping forever.

Using plugins and programs such as password managers is also fraught with the security risk, as having access to such a utility empowers cyberthieves to do more than just obtain your credit card info; it opens them up to a great amount of personal details.

Preventing an autofill-related theft

So what can you do to avoid falling prey?

Using Mozilla Firefox is one of the easiest available solutions. As of today, Mozilla hasn’t devised a mechanism that affords its users the same convenience that Chrome and Safari users enjoy with autofill. When filling web forms on Firefox, users still have to manually pre-fill each data field due to a lack of a multi-box autofill functionality – a blessing in disguise, given the potential for victimization in autofill-enabled browsers.

Another quick fix is disabling the autofill feature on your Chrome, Safari and Opera (for Apple mobile devices) browsers. This would mean that when filling out web forms, you’d have to manually type responses for every field again, but at least you’d be more secure.

It’s not exactly the most sophisticated form of online data and identity theft, but complacency can result in being victimized by cyber swindlers. Take the first step in ensuring your systems’ safety by getting in touch with our security experts today.
