PatchWorkApt Ransomware is a New Chaos Spinoff

PatchWorkApt is a newly discovered variant of the Chaos ransomware. Upon infiltrating a computer system, PatchWorkApt encrypts files, adds a series of random characters to filenames, and generates a ransom note named "look_this.txt."

An illustration of the renaming pattern applied by PatchWorkApt to encrypted files is as follows: "1.jpg" transforms into "1.jpg.b621," "2.png" becomes "2.png.xp9y," and so on. The ransom note alerts the victim that their network has been compromised, with all data on their systems encrypted using the AES-256 algorithm. It emphasizes the exclusive possession of the decryption key by the attacking group and warns against attempting recovery without it, citing potential irreparable damage.

The group responsible for the attack, explicitly stating their financial motives, encourages the victim to trust them and initiate contact to negotiate terms for decrypting the files. In an effort to build trust, they propose sending encrypted files for verification. Contact details are provided via email addresses (patchworkapt@tutanota.com and patchworkapt@msgden.net), assuring the victim that, upon payment, the group will furnish the necessary decryption key software for restoring the files.
