Threat Database Ransomware ORCA Ransomware

ORCA Ransomware

The ORCA Ransomware is a malware threat equipped with potent encryption capabilities. Once it has infiltrated the targeted computers, the threat will lock the various files stored there - documents, PDFs, archives, databases, images, photos, etc. Restoration of the affected files without the proper decryption keys is typically impossible. When cybersecurity researchers analyzed the ORCA Ransomware, they discovered that it is a variant of the ZEPPELIN malware family.

Victims of the threat will notice that their files have had their original names modified. Indeed, the threat adds '.ORCA' followed by an ID string generated specifically for the victim as new file extensions. Affected users or organizations also will notice that an unfamiliar file named 'HOW_TO_RECOVER_DATA.hta' has appeared on the desktop of the breached devices. The purpose of the file is to deliver a ransom note with instructions from the attackers.

According to the message, besides locking the victim's files, the threat actors also have managed to exfiltrate important confidential data that is now stored on their private server. This is a common tactic employed in double-extortion operations. Victims are given 72 hours to pay a ransom in Bitcoin. After that period is over, the hackers threaten to delete the decryption key needed for the restoration of the locked files. In addition, if they do not receive the asked payment, the hackers also will publish the collected data to the public. The ransom note mentions two email addresses - '' and ',' as potential communication channels
