Root cause

Root-cause analysis not yet published. The incident description below contains all currently available signal — review the attack transaction directly for definitive forensics.

Forensic narrative

By deploying the attack contract and using the same algorithm as FFgame to calculate the random number in the contract, the attacker immediately uses the random number attack contract in inline_action after generating the random number, resulting in the winning result being "predicted", thus reaching the super high winning rate. Attack method (per SlowMist): Random number attack. Reported loss: 1,331 EOS.
