Ransomware threat mailed in letters to business owners | Malwarebytes

Business owners across the US received letters claiming to be from BianLian, a ransomware group, demanding cryptocurrency ransom for stolen data. The letters, which threaten data leaks if the ransom is not paid within 10 days, are likely the work of copycats due to inconsistencies with BianLian’s typical tactics. Small businesses should notify their IT teams immediately if they receive such letters.
