The Poloniex and HTX/Heco Bridge exploits as well as the KyberSwap flash loan attack were the three largest incidents in November, according to blockchain security firm CertiK.

The cryptocurrency industry has now seen its most “damaging” month for crypto thievery, scams and exploits, with crypto criminals walking away with $363 million in November, according to a blockchain security firm.

Around $316.4 million came from exploits alone, flash loans inflicted $45.5 million in damage, and $1.1 million was lost to various exit scams, CertiK stated in a Nov. 30 X (formerly Twitter) post.

The largest exploits in November occurred on Poloniex and HTX/Heco Bridge, with losses of $131.4 million and $113.3 million, respectively.

The third largest exploit was inflicted on a single victim who lost $27 million from a phishing attack.

Meanwhile, the $45 million KyberSwap attack accounted for nearly all damage done for flash loan attacks in the month.

The latest monthly figure has surpassed an earlier record of $329 million, set in September, caused mainly by the $200 million Mixin Network attack.

As of the end of November, about $1.7 billion has now been lost to exploits, exit scams and flash loan attacks in 2023. This makes up only 54% of the crypto drained in the full year 2022, when $3.7 billion was drained to crypto incidents, while 2021 saw losses of $1.7 billion, according to CertiK.
