Ransomware Attacks

Kraken Ransomware Disguises Itself As Legitimate Anti-Spyware Software

Everything isn’t always what we seem.  This is something we have come to know and accept.  However, when we download a program that is supposed to protect us, that is what we expect it to do.  Apple users were recently duped with Adware Doctor, which positioned itself as an adware prevention tool, but actually was spying on user behavior.  Now, hackers have used the name and logo of the SuperAntiSpyware, an anti-malware tool, to trick users into downloading the ransomware deemed Kraken.

Kraken Uses Security Program Name and Logo to Spread to Unknowing Victims

To be clear, SuperAntiSpyware is a legitimate anti-malware tool.  However, Kraken stole the company’s logo and name to target users.  The only difference between the Kacken and the legitimate program executable files are one letter in the file name.  SuperAntiSpyware uses SUPERAntiSpyware.exe, while Kraken uses SUPERAntiSpywares.exe.  Now, for those users who downloaded the legitimate program, you would not be impacted by this.  However, those who downloaded the malicious file would experience encryption of various files.

Once a user opts to download SUPERAntiSpywares.exe, the malicious executable begins to run.  The only time this will be blocked from running would be if the user was employing a security solution that was using an application whitelist.  Or, if blacklist antivirus companies are updating the blacklist to include SUPERAntiSpywares.exe.

If the file is allowed to run, it will first ensure the location of the device is not in a certain geographical area.  For instance, if the device is in Iran or Brazil, the ransomware will not execute.  Assuming you are in a location they have deemed acceptable to encrypt, the malware will scan the device for files with a variety of file extensions, including .jpeg, .doc, .zip, etc.  Once these files are recognized, they are renamed with the file name 00000000-Lock.onion and encrypted.

At this time, there is no free option for decrypting files that have been locked by the Kraken ransomware.  The only way users can restore locked files would be through their backup files.
