According to ransomware.live, 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.
