Following the massive $41 million hack of cryptocurrency casino Stake, the hackers responsible have executed another series of transactions involving Polygon (MATIC) and Binance Coin (BNB) tokens, totaling $328,000.

These recent maneuvers come in the wake of the exploit that occurred on September 4 and have been monitored by blockchain security firm CertiK.

In the most recent transfer, 300 BNB tokens valued at approximately $61,500 were sent to an externally owned address with the identifier “0x695…” These tokens were subsequently bridged to the Avalanche blockchain on September 11 at 4:09 pm UTC.

Additionally, 520,000 MATIC tokens, worth over $266,000, were moved to the Avalanche blockchain seven hours earlier, at 7:18 am UTC.

These transfers of 520,000 MATIC and 300 BNB tokens, totaling $328,000, supplement the previous $4.5 million in stolen funds that were transferred to the Bitcoin blockchain in the form of BTC on September 7, as reported by blockchain security firm Arkham.

However, it’s important to note that the total of $4.8 million transferred so far represents only 1.2% of the $41 million stolen by the hackers in the initial heist.

The hackers gained access to the private key of Stake’s Binance Smart Chain and Ethereum hot wallets, enabling them to execute the hack on September 4.

The United States Federal Bureau of Investigation (FBI) has indicated that it believes North Korea’s Lazarus Group was responsible for the exploit.
