Crypto suffered its worst month of the year for hacks and exploits in September, with two blockchain security firms estimating losses at more than $766 million.
PeckShield counted 55 major incidents resulting in $766.5 million in stolen funds, while CertiK recorded 97 incidents and estimated losses at $768.4 million. Both firms showed the losses were a significant increase from August.
The month included the $388 million Bitget hack and a $320 million hack of the Liquid Network. More than $270 million was later returned, according to reports. The incidents rank among the largest crypto thefts of the year.
“September was a stark reminder of how quickly the threat landscape can shift,” CertiK said in a statement Wednesday.
Other crypto hacks in the month included Safe Wallet, DCENT, and Duelbits, which lost $7.8 million, $6 million and $5.9 million, respectively.
