Binance ‘red teams’ its own staff every month to keep hackers out
Cryptocurrency exchange Binance has been running simulated phishing attacks against its own employees for the past four years and can fire staff who repeatedly fail the tests, according to Binance chief security officer Jimmy Su.
The fake attacks are conducted by Binance’s red team, an internal ethical hacking unit whose job is to break into systems to identify vulnerabilities.
“We do phishing attacks on our own employees on a monthly basis just so we understand if our security hygiene is improving,” Su told Cointelegraph. “The ones that have failed it, we will do remediation training.”
In February, AMLBot estimated that 65% of crypto security incidents in 2025 were driven by social engineering.
