Malware seems to be everywhere these days with scammers hiding it in everything from fake job offers to LinkedIn Smart Links. Today, however, we have news of malware being pumped into even the most inconspicuous of places, the Windows logo itself. It seems that malicious actors have shipping out dangerous malware hidden in image files and that even the Windows logo has been affected in this manner. Here is what you need to know.
Cybersecurity experts at Symantec have discovered a new way that threat actors have been trying to catch out unsuspecting victims. The malicious method is called steganography and involves hiding malware code into images.
According to the Symantec report the campaign, which is being perpetrated by a cybercriminal gang called Witchetty hides an XOR-encrypted backdoor malware in a bitmap image of an old Windows logo. Interestingly, the compromised file is hosted on a cloud service that wouldn’t normally be flagged as being suspicious, which is what allows it to evade security scanners.
The XOR-encrypted backdoor allows the scammers to perform various actions, which will cause the victim harm including altering and editing files and folders, starting and terminating processes, downloading further infected files onto the device, stealing files and documents, and even messing around with the Windows Registry.
Incredibly, it seems like this type of attack has successfully targeted several institutions including several governments in the Middle East and even the South African Stock Exchange.
Again, however, this is just another example of why you need to be more careful than ever these days when you are using your computer and online.
