Announcement for Flash Loan Attacks Pancake Bunny
We are writing to share several facts about the economic exploit that crashed Pancake Bunny. The flash loan was caused by new smart contracts which HAECHI AUDIT team did not audit.
HAECHI AUDIT audits PancakeBunny smart contracts on 18th January 2021 and here is the report. This report warned the fact that there are non-audited and changeable external contracts, and the “helper” function is weak to flash loans’ attack.
After offering the auditing, the Pancake Bunny team upgraded v1 contracts to v2 and chose another partner for auditing. This flash loan was caused by new smart contracts we did not offer to audit.
We are sorry for what has happened this time, and we are ready to assist the Pancake Bunny team in solving the problem. Pancake Bunny team shared their post-mortem analysis here.
