CoinJoin Activity Emerges in $6.36 Billion Binance Hack

CoinJoin activity has emerged in the movement of funds tied to the reported $6.36 billion Binance hack, adding a new laundering development to one of the largest crypto thefts. It marks the first use of CoinJoin to launder funds tied to the incident.

The theft occurred Oct. 29, 2026, and involved about $6.36 billion in digital assets. Authorities have frozen about $3 billion of the stolen funds. The laundering activity involved 11 blockchains and more than 40,000 transactions, alongside the use of CoinJoin.

The movement has raised concerns about exchange security and the handling of stolen crypto. Binance is the world’s largest cryptocurrency exchange and facilitates billions of dollars in daily transactions, giving the incident significance beyond the funds directly involved. Traders are monitoring what the theft means for market stability and security standards across exchanges.
