'.0ff File Extension' Ransomware

'.0ff File Extension' Ransomware Description

The '.0ff File Extension' Ransomware is a member of the Filecoder family of file-encrypting Trojans. Its attacks can modify and block your files by enciphering their contents, with other symptoms including various formats of text messages soliciting ransom money. Backup strategies can alleviate the need for decrypting the above data, and anti-malware programs can remove the '.0ff File Extension' Ransomware at any point of the infection.

A Trojan Coming Back out of Retirement

Activity in Trojan campaigns can be inconsistent sometimes, either due to questionable methods of distribution or changes in the threat actor's administrative actions. Even though many Trojans earn media attention from sustained spikes of activity that proceed to fall off completely, others, like the '.0ff File Extension' Ransomware, may vanish for a time, only to appear again months or years later. This stasis period doesn't seem to have been caused by any significant updates to the '.0ff File Extension' Ransomware, which is using many of the same components previously detected by the cyber security industry one year ago.

Malware researchers began to find signs of renewed activity in November, possibly as a result of new e-mail spam, exploit kit-based drive-by-downloads or hacked RDP systems. The '.0ff File Extension' Ransomware's installation may self-terminate the program in well-protected machines, such as virtual environments, to prevent its analysis. In cases where the Trojan is allowed to complete its payload, the '.0ff File Extension' Ransomware scans local, network-mapped and removable drives for certain files and encodes them with a (currently uncracked) encryption algorithm.

Although the victim can ascertain the file damage quickly by looking for data using the '.0ff' extension that the '.0ff File Extension' Ransomware inserts into the names, they're unusable without a decryption procedure. The '.0ff File Extension' Ransomware then drops a Notepad file containing its ransom message asking you to use Bitmessage to initiate communications with the threat actors. Malware experts failed to find any further information about fees in demand for the decryption service, although an extorted sum often starts at several hundred dollars, at a minimum.

Pulling an Old Trojan '0ff' of Your Files

While it can be tempting to assume that a Trojan that's no longer in news headlines is no longer a problem, the '.0ff File Extension' Ransomware and threats like it testify as to the continuing efficacy of even out of date threat campaigns. Standards for protection against its most probable distribution tactics include many of the steps malware experts suggest habitually for all PC users, including maintaining your backups, keeping to a rotation of passwords, and monitoring browser settings for potentially exploitable features. Fully reversing the file damage the '.0ff File Extension' Ransomware causes may not be possible, which places additional importance on preventing an infection.

Due to its age, most anti-malware products should have few or no issues with identifying and removing the '.0ff File Extension' Ransomware, which is detectable as being a variant of FileCoder typically. While the above constitutes the majority of this threat's activities, malware analysts also note some minor network activity that may benefit the threat actors controlling the '.0ff File Extension' Ransomware. Use Safe Mode or alternate system boot-up options for disabling this threat before you scan your computer.

'Old but not yet dead' is the rallying cry of Trojans like the '.0ff File Extension' Ransomware, which you shouldn't underestimate for the potential harm they're capable of causing.
