Crypto Security Roundup: Binance Laundering, Bitcoin Core Flaws and Gnosis Pay Breach

Summary
A crypto-security roundup covers Elliptic's account of laundering linked to the Binance breach, a Gnosis Pay data breach, U.S. action against MEXC, three Bitcoin Core flaws, Keplr wallet fund recovery and cryptocurrency theft cases.
Key points
- Elliptic reported that attackers behind the Binance breach routed stolen cryptocurrency through disposable memecoins. The FBI attributed the breach to North Korea's TraderTraitor group; Binance had replenished virtually all stolen customer assets, and Elliptic estimated $2.85 billion was frozen.
- Gnosis Pay said attackers accessed an older card-support system on Nov. 3, exposing customer information. The company contained the breach, replaced credentials and made 3D Secure mandatory until retiring the affected system.
- The U.S. Treasury cut MEXC Global off from the U.S. financial system over allegations that it facilitated $16 billion in transactions linked to Iran, North Korea and Russia. MEXC said operations and customer assets were secure.
- Bitcoin Core disclosed three flaws that could disrupt mining, delay block processing or weaken protections for nodes using specific Tor settings. Fixes were released in versions 30.0 and 29.2.
- Web3Auth moved about $5.6 million from vulnerable Keplr wallets to recovery addresses after a breach exposed some users' private keys. The amount attackers may have stolen was not disclosed.
- A Scottish court sentenced three people for plotting a cryptocurrency theft using a plan to coerce victims into installing AnyDesk; the attempt failed when the victims refused entry.
- Former FBI agent Patrick Steven Yaroch pleaded guilty to stealing about $2.47 million in cryptocurrency from wallets connected to FBI investigations. He must pay at least $2.4 million in compensation under his plea agreement.

- Elliptic reported that Binance attackers used newly created memecoins and complex transactions to launder stolen cryptocurrency; Binance said it had replenished virtually all affected customer assets and was gradually restoring withdrawals. Gnosis Pay disclosed customer information after unauthorized access to an older card-support system, but said it contained the breach, customer funds were safe, and its separate business platform was unaffected. U.S. authorities cut MEXC Global off from the American financial system over alleged illicit transactions. Bitcoin Core disclosed three vulnerabilities that could disrupt mining and transaction processing or weaken network protections; fixes were released in versions 30.0 and 29.2. Other reports included a failed cryptocurrency theft plot in Scotland, protective transfers of about $5.6 million from vulnerable Keplr wallets, and a former FBI agent’s guilty plea to stealing cryptocurrency from wallets linked to investigations.
