What is FlatChestWare?

FlatChestWare is a virus based on an open-source ransomware project called Hidden Tear. This malware was first discovered by virus security researcher, Karsten Hahn.

FlatChestWare is designed to stealthily infiltrate systems and encrypt stored data using AES-256 cryptography. In doing so, the virus appends filenames with the ".flat" extension. For example, "sample.jpg" is renamed to "sample.jpg.flat". After successfully encrypting files, FlatChestWare opens a pop-up window containing a ransom-demand message.
