Anti-virus maker Avast has released a free decryptor for victims of the BianLian ransomwareto help them recover their files without paying a ransom.

The BianLian ransomware (not to be confused with the same-name Android malware) first emerged in August 2022, and is known to target manufacturing, education, healthcare, professional services, energy, banking, financial services, and insurance (BFSI), and the entertainment industry.

Avast notes that the decryptor works only for files encrypted by a known variant of the BianLian ransomware. For new victims, it may be necessary to find the ransomware binary on the hard drive. However, because the ransomware deletes itself after encryption, it may be difficult to do so.

A step-by-step instruction on how to use the decryptor along with IoCs (Indicators of Compromise) related to the threat as available in the company’s blog post.
