BianLian

As of Oct 19, 2026, BianLian has listed 529 confirmed victims on its leak site since Dec 12, 2022, 1.6% of all victims tracked by Brandefense. Its most targeted country is United States (50.9% of its victims) and its most targeted sector is Consulting.

BianLian ransomware operations began in late 2021. The group practices multi-pronged extortion, demanding payment for a decryptor, as well as the non-release of stolen data. The ransomware group hosts a public, TOR-based, blog to post victim identities and stolen data. Somewhat unique to BianLian at the time of their launch was their inclusion of an I2P mirror for their blog.
