Blockchain security company BlockFence identified the Bitcoin address used in the theft, and on-chain data from linked Ethereum addresses revealed multiple high-value transactions to various addresses.
According to fellow blockchain analysis firm PecShield, the stolen funds were moved through the Ethereum mixer eXch shortly after the hack, complicating the traceability of stolen assets. Peckshield said a small portion of the funds were moved to HitBTC and CoinSpot, and the wallet addresses were labeled as “FixedFloat Drainer.”

After the hack, FixedFloat initially cited “minor technical issues” and placed the system in “maintenance mode.” This was before the full extent of the hack was revealed, causing confusion and concern among users.

The exchange subsequently assured that users' funds were safe and that the stolen funds only affected the company's internal operations. If so, the hack likely took place from one of the exchange's hot wallets.

FixedFloat, which touts “instant, fully automated cryptocurrency exchange using the Lightning Network,” prioritizes privacy over security and operates without the need for account registration or identity verification.

Despite a slight increase in individual hacking incidents, the total amount of funds stolen decreased by approximately 54.3% to $1.7 billion. This is mainly due to rapid changes.
