Ransomware attacks are becoming extreme these days and computer security experts keeps on sending warnings to people about this hazardous threat; hence, there are still many computers being infected with this highly dangerous threat due to negligence of users. In fact, there is an unprecedented increase of attack in recent years and one of the top offenders is STOP ransomware family. This group of virus has generated over a hundred of variants because their handlers found that file-locking virus is a perfect tool to easily swindle money from victims. Among the previous releases of this threat includes Mbed, Kodg, and Grod.

This day, new variant from the group has emerged with label Zobm ransomware. Similar to earlier releases, this latest threat was designed to corrupt major files on the computer by encrypting them with a complex algorithm. The ransom virus also adds a suffix .zobm extension to every encrypted file to identify the infection type. To site an example, a file word.doc will turn into word.doc.zobm after it was encrypted by the Zobm ransomware. Reminding victims and instructing them on how to proceed with the recovery of .zobm file is clearly stated on the ransom note generated on the same location as compromised data.

As what was declared in the document, victims are required to pay $980 in exchange of personal private key and decryption software. Hence, handlers of Zobm ransomware are ready to dispose the recovery items for only $490 if victims can meet the 72 hours transaction period from the time of initial attack. Here is an excerpt from the ransom note.
