Adding up to the extended list of ransomware under STOP family is called Gero. Malware researchers discovered that this new variant has no notable changes than its predecessors. Only the appended extension is literally updated on this edition. As such, data that were infected with this ransomware will bear the .gero file extension. It targets user’s valuable files with formats like .doc, .xls, .ppt, .jpg, . pdf, . dwg, .zip, .rar, .dwg, .htm, and many more. To give an example, file presentation.ppt will transform into presentation.ppt.gero after it was fully encrypted with Gero ransomware.

These two file alteration processes really make it impossible for users to open them without the private key and decryption software combination.
