The cryptocurrency industry has experienced a devastating "Black November," recording approximately 15 significant attacks with total losses nearing $194 million. According to PeckShield's analysis, this figure represents an astonishing 969% increase compared to the $18.18 million lost in October.

The enormous scale of the losses was driven by several large-scale exploitation events. Balancer v2 and its forks suffered the biggest hit, accounting for total losses of $137.4 million, although a portion of this ($39 million) was successfully recovered. Other significant victims include the exchange Upbit, with losses of $36 million, Yearn Finance with losses of $9 million, and HLP, which faces a loss of $4.95 million due to bad debts. Additionally, GANA PayFi was exploited, resulting in a loss of $3.1 million. This dramatic rise in the number of successful attacks highlights the persistent security vulnerabilities within the decentralized finance (DeFi) ecosystem.
