Revised Banking Trojan Made More Dangerous Borrowing from WannaCry and EternalBlue

For all the Mac users out there, it’s time to just face it, join the rest of the world and recognize that your devices can also be infected with malware. In fact, one that specifically targets Mac users has been updated and revised to use some infection methods of last May’s WannaCry (ransomeware) and EternalBlue (remote control malware) outbreaks that shut down companies all over the world.

Specifically, this revised malware, Retefe, exploits a vulnerability in the Windows operating system, as opposed to Mac systems, and redirects users who want to go to their online banking sites to a replica site. If credentials are entered, that login information is given up to the cyberthieves.

But that doesn’t mean the former version of it isn’t roaming around out there looking for Mac devices to attack. In fact, it’s still quite active.

It’s important to note that the vulnerability has, in fact, been fixed. That happened a long time ago. If you have not updated your operating system in a while, take a moment to do that, specifically if you are using Windows.  It is important to make sure that whenever an update is issued for a critical or security vulnerability that you apply it as soon as it’s made available, regardless of what operating system you are using.

Malware is often revised and sent out to find more victims. Once it’s detectable by various anti-malware products and methods, the authors try to change it enough to find additional victims. They are often very successful doing this.

Always stay on guard and be on the lookout for phishing sites as well. Even if you are one of the diligent ones that is always on top of patching and updating all products, it won’t stop a phishing attack that comes in through your email. These are successful because they are able to bypass anti-spam and anti-phishing products. It relies on you paying attention and recognizing that a message may be trying to bait you.
