In a July interview, Binance's chief security officer, Jimmy Su, highlighted the risks of fake job interviews that could compromise employee devices, a tactic later used in the exchange's record-breaking $6.3 billion hack. Su explained how attackers could persuade employees to run malicious code during technical assessments, leading to credential harvesting. Binance's investigation revealed that a software engineer downloaded a malicious coding assignment during a fake interview, which was part of a multistage attack. The company has blocked 57 suspected North Korea-linked cyber threats this year, averaging one attack every five days.
