From September 19 to September 25, 2022, all security incidents that have occurred are Security Hacks.
SECURITY HACKS:
1. Wintermute’s Founder, CEO Announces Hack on Platform
On September 20, Founder and CEO of crypto market maker Wintermute Evgeny Gaevoy announced that the platform had been hacked, with the attacker exploiting the leaked private keys to steal crypto assets worth at least US$160 million.
According to a statement, the team behind Wintermute had used a vanity wallet address generator tool Profanity to create a wallet for gas fee optimization. This tool had a vulnerability that had compromised some private keys which were subsequently abandoned. Due to a mistake in Wintermute’s manual operations, the leaked private keys were not removed and were later used by the hacker to exploit crypto assets.
This was not the first time Wintermute was attacked. In June 2022, Wintermute was exploited by hackers and lost 20million OP tokens.

2. Hacker Attacks Fortunas Finance Through Multiple Attacking Contracts
On September 22, a hacker used four attacking contracts to deploy an addition 250 contracts to attack Fortunas Finance, a DeFi application deployed on the BNB chain.
The attacker conducted a flash-loan for Fortuna tokens in KnightSwap, and repeatedly called on token transfers using these tokens among the deployed 250 contracts. Doing so resulted in minting a large quantity of Fortuna tokens without consuming BUSDs. The attacker later paid back the flash-loan and exchanged the remaining Fortunas to BUSDs on Pancake.
Around 180000 BUSDs were exploited in this incident.
