December 2025: Crypto Security Situation with 26 Major Incidents

December 2025 presented a mixed report for the cryptocurrency industry. A total of 26 major attacks resulted in a total loss of $76 million – a significant decrease compared to the previous month, which reported $194.27 million. This represents a decline of over 60 percent within four weeks.

Particularly Critical Security Incidents

Two cases deserve special attention. The wallet address 0xcB80…819 was drained of $50 million through an Address Poisoning attack – a tactic where fake addresses trick users into making incorrect transactions. Another significant incident involved the multi-signature address 0xde5f…e965, which suffered a loss of $27.3 million due to a Private-Key leak.

The data comes from PeckShield, a renowned security analysis team in the industry. December again highlights that despite increased security standards, targeted attack vectors such as Address Poisoning and Private-Key compromises continue to pose substantial financial risks.
