PANews reported on January 26 that, according to BlockSec Phalcon monitoring, a series of suspicious transactions targeting victim contracts deployed on Ethereum, Arbitrum, Base, and BSC were discovered several hours ago. These transactions, originating from contracts deployed by two creators, resulted in an attack and total losses exceeding $17 million. The victim contracts were not open source and appeared to contain an arbitrary call vulnerability. The attackers abused existing token authorization to execute transferFrom operations to steal assets.

Affected deployers:

• 0xbeef63AE5a2102506e8a352a5bB32aA8B30B3112 — Loss of approximately $3.67 million;
• 0x9cb8d9BaE84830b7F5F11ee5048c04a80b8514BA — Loss of approximately $13.41 million.
