This amounts to about $15,000 US.Ĭybersecurity strategist Nick Bilogorskiy with Juniper Networks told SecurityWeek, "It is a pretty clever trick to embed the ransom demand inside the DOS payload. It demanded GitHub hand over 50 XMR (Monero cryptocurrency). The message was embedded within a line of Python code that was delivered by the compromised machines. However, cybersecurity firm Cybereason reports that analysis of the data payload revealed a ransom note. Initially, the attack seemed to be random. These volumes were achieved using a reflection/amplification vector that exploits memcached servers to amplify the attacker's sent data by a factor of 51,000. Initially, GitHub reported the attack peaking at 1.3 Tbps, but this week DDoS mitigation service Netscout Arbor confirmed that the peak was closer to 1.7Tbps - 2.5 times bigger than the previous record. The directed denial of service only incapacitated the site for around nine minutes, but the strike pummeled servers with data volumes reaching almost 2Tbps. As we reported last week code repository, GitHub was hit with the largest DDoS attack ever recorded on Wednesday.
