Techub News reports that, according to BlockSec Phalcon monitoring, a series of suspicious transactions occurred a few hours ago on networks such as Ethereum, Arbitrum, Base, and BSC. Two creators' deployed contracts were attacked, resulting in a total loss of over $17 million. BlockSec stated that the affected contracts are not open source and may have a vulnerability in the "arbitrary call" function. Attackers exploited existing token approvals and transferred assets via transferFrom operations; among them, the address starting with 0xbee lost approximately $3.67 million, and the address starting with 0x9cb lost approximately $13.41 million.
