On 15 December 2017, a Russian bank lost somewhere between $100,000 and $1 million US dollars after hackers sent SWIFT wire transfers abroad to Europe, Asia, and America. The bank was compromised (medium confidence) by a hacker group who sent malicious attachments to a number of different banks a few weeks prior. SWIFT was not compromised, but was used as a tool to siphon money from the compromised bank. The bank is going through ownership reorganization. Prior to this incident, it was receiving financial regulator warnings regarding its cyber security posture.
