Silent ransomware

Unlike many other groups, Silent claims to operate with a high level of anonymity and discretion. According to their own statement, they avoid public negotiations and encrypt minimal data. Instead, their focus is on stealing valuable confidential corporate information — and either selling it to competitors, on the dark web, or publishing it selectively.
