Bl9c98vcvv Ransomware

Posted: September 21, 2020

The Bl9c98vcvv Ransomware is a file-locking Trojan that's from the Xorist Ransomware kit. The Bl9c98vcvv Ransomware can block files with its familial encryption routine, with personal and work media being highly at risk of not opening. Trustworth anti-malware tools should remove the Bl9c98vcvv Ransomware, although users may or may not have recovery options for their files besides previous backups.

A Trojan Kit Keeps Up the Bad Work

Free Trojan resources might not have the same infamy as Ransomware-as-a-Services, but many hackers worldwide rate them as equally valid options for holding files hostage. Among these 'freeware' file-locker Trojans, the Xorist Ransomware family finds itself in the threat landscape more often than many of its competitors. With the Bl9c98vcvv Ransomware, it also shows that Europe isn't far from the thoughts of Trojan-abusing criminals.

The Bl9c98vcvv Ransomware's family is well-known, with variants in 2020 like the Xorist-TAKA Ransomware and the Zasifrovano Zaplat Ransomware, along with aging members like the Crypto1CoinBlocker Ransomware and the TaRoNiS Ransomware. The thirteen-kilobyte Bl9c98vcvv Ransomware installer uses random alphabet character names and has no unusual copyright details or signatures. Like other versions of its Trojan-making kit, it targets Windows systems.

Once the user (or an attacker) installs it, the Bl9c98vcvv Ransomware can encrypt any files that the threat actor configures it to harm. However, many formats, such as Word documents or JPG pictures, are high risks. The Bl9c98vcvv Ransomware may use either XOR or TEA-based encryption routines to locate these files and give the threat actor his bargaining leverage.

A telling addition to the Bl9c98vcvv Ransomware is its pop-up warning format, which has English and Portuguese languages. The Trojan also specifies a Paysafecard or Ukash-based payment, making it almost sure that its campaign targets European victims.

No-Cost Fixes for Anyone's Priceless Files

Since the Bl9c98vcvv Ransomware is the progeny of a no-programming-needed kit, it may use equally-crude infection vectors, such as torrents that are a favorite among some Ransomware-as-a-Service families. Threat actors also have other possibilities for infecting Windows systems, such as targeted e-mail attacks with poisoned attachments, watering-hole attacks against websites, or brute-forcing admin logins. Users practicing the basics of Web-browsing safety protocols shouldn't have any significant risk of exposure to the Bl9c98vcvv Ransomware or most drive-by-downloads.

Solutions to file-locking Trojan infections are few. Victims may choose to:

  • Recover from a backup from an unaffected device (USB, cloud service, etc.)
  • Create copies of 'locked' files for testing with free Xorist Ransomware decryptors
  • Pay a ransom for potentially no additional help

Depending on the Trojan's payload operations and origin, decryption isn't always available or perfect. Malware analysts strongly encourage making full use of backup strategies to recover all media that's worth ransoming in the first place.

Anti-malware services provide a fourth option and should identify and block most Xorist Ransomware variants. Users protected by these services can delete the Bl9c98vcvv Ransomware securely.

Free software can be a wellspring of problems as much as education or entertainment, and Xorist Ransomware's Trojan-building kit is robust evidence of it. When a campaign like the Bl9c98vcvv Ransomware's comes knocking, users who don't have their security ready might end up throwing vouchers at bad-faith actors.
