Ransomware threat mailed in letters to business owners

Researchers observed a snail-mail extortion campaign in the United States in which recipients—primarily business owners and CEOs—received customized ransom letters claiming BianLian had stolen sensitive corporate data and demanding $250,000–$350,000 in cryptocurrency within a 10-day deadline; analysts suspect copycats rather than confirmed intrusions but warn small businesses to involve IT/security to verify and remediate.
