Nov. 12,U.S. cybersecurity firm Kaspersky's investigation into the leak of the private keys of margin trading lending platform bZx found that the phishing attack against bZx was likely carried out by the Lazarus (Bluenoroff Advanced Persistent Group) group, which has a long history of attacking financial institutions and cryptocurrency currency exchanges, has close ties to North Korea, and is known as a state-sponsored hacking group. The Kaspersky investigation analyzed a number of attacks conducted by Lazarus in 2017, 2019 and 2020 and found similarities between the phishing emails for that private key incident and the tools used in previous attacks. In previous news, on November 5, the private keys deployed by the margin trading lending platform bZx at Polygon and BSC were compromised, resulting in the theft of more than $55 million in funds, in a phishing attack that targeted bZx developers.
