Bitcoin has a new and potentially considerable threat to its reputation, if California cybersecurity firm Proofpoint is correct. Last week, the company warned that a previously undocumented ransomware sample that they found, CryptXXX, would not only be encrypting files locally and on all mounted drives, “it’s stealing Bitcoins and a large range of other data.”
Not only is CryptXXX a multi-purpose thief, but the company's analysis shows it spreads in new and powerful ways; through a common trojan called Bedep after infection via the extremely popular Angler exploit kit.
