[ETC Hit by Social Engineering Attack, Fake Core-Geth Security Update Once Misled Some Mining Pools to Switch] Odaily Planet Daily News: Ethereum Classic recently experienced a social engineering incident involving the Core-Geth client. An unreviewed version of ethereumclassic/core-geth v1.13.0 was released on September 14 and promoted as a security update. A small number of mining pool nodes briefly switched to this version but have since reverted to the long-maintained etclabscore/core-geth v1.12.23. The unreviewed version modified critical logic such as chain selection and node discovery, posing potential risks of network splits. The incident did not result in block loss, chain reorganization, fund loss, or service interruptions.
