Bnb Chain

Pink Drainer was a pseudonymous wallet-drainer-as-a-service operation that supplied phishing kits and malicious smart-contract infrastructure to affiliate scammers between roughly April 2023 and May 2024. Security researchers, principally Scam Sniffer and blockchain investigator ZachXBT, attribute upward of $75-85 million in stolen crypto assets across an estimated 20,000-21,000+ victims to wallets and infrastructure linked to the group before it announced its retirement in May 2024. No law enforcement agency has publicly identified or charged the individuals behind the operation, so all attributions of activity and identity in this report come from private security researchers rather than courts or regulators.

Tapioca DAO is an omnichain DeFi money market built on LayerZero, offering a CDP stablecoin (USDO) and isolated lending markets (Singularity/Big Bang) across Arbitrum and BNB Chain. On October 18, 2024, the protocol suffered a critical security breach when a team member was targeted by a social engineering attack attributed to North Korea's Contagious Interview campaign, resulting in private key compromise, drainage of TAP token vesting contracts, and the minting of 5 quintillion USDO. Approximately $4.4–4.7 million was stolen before a partial counter-exploit recovered roughly 996 ETH (~$2.7 million), leaving the protocol treasury down approximately 45% and the TAP token price collapsed over 95%.

Nexera (formerly AllianceBlock) is a blockchain infrastructure protocol focused on compliant real-world asset tokenization, operating primarily on Ethereum. In August 2024, a threat actor later attributed to North Korea's Lazarus Group used social engineering and BeaverTail malware to steal smart contract management credentials, enabling unauthorized transfer of 47.24 million NXRA tokens valued at approximately $1.9 million. The team mitigated further losses by zeroing out and subsequently burning the 32.5 million tokens that remained in the attacker's wallet, limiting confirmed liquidated losses to roughly $449,000.
