Coral's wRAM was attacked by hackers, resulting in a loss of more than 120,000 EOS

According to data from the PeckShield situational awareness platform, at 01:43 am on September 10, the wRAM of the EOS ecosystem DeFi liquidity mining project "Coral" was hacked, resulting in a loss of more than 120,000 EOS. So far, 46,000 EOS have been transferred to ChangeNOW for money laundering.

Security personnel further analyzed and found that the ph***bj attacker account used a similar "reentrancy attack" mode to attack the eoswramtoken contract. Specifically, the attacker embedded an inline transfer in the normal transfer operation, causing the wRAM contract to have problems in judging the RAM amount during mint, resulting in multiple issues.
