December 2025 marked a very significant shift in the crypto security landscape as the number of losses that came from crypto platform exploits reduced to about $76 million across 26 major incidents.
According to the reports, this number represents a decline of over 60% compared to November’s hack that caused a loss of $194.27 million, signaling a reduction in the scale and frequency of successful attacks.
PeckShield Crypto Hack Report for 2025
According to the report shared by Peckshield, the December hack was very concentrated on few platforms. Unlike the other months in 2025, where 5-10 platforms accounted for the total number of hacks, in December two incidents accounted for the majority of stolen funds.
Two of the most severe cases, according to Peckshield, involved wallet address poisoning, where wallet ‘0xcB80…819’ lost roughly $50 million after interacting with a wallet that was designed to drain funds.

That particular incident opened the eyes of many people to see how users are vulnerable to social and interface-level attacks. The other involved a significant breach that used a multisig wallet labelled as ‘0xde5f…e965’ to be drained of $27.3 million, due to a private key leak.
Multisig wallets have been regarded as one of the strongest safeguards recorded in crypto custody, yet this event shows that when private keys are compromised, even the most robust on-chain structures can fail.
Finally, one of the major hacks that shaped December 2025 was the Christmas Trust Wallet breach. According to Tronweekly, the breach resulted in losses estimated around $7 million, alongside a separate breach that impacted the Flow protocol with damages close to $3.9 million.
Taken together, December’s data paints a mixed but also cautiously optimistic picture that explains that while there has been a significant and overall drop in the month-to-month losses and an improving defensive system, there are also serious operational lapses and also social engineering that shows that the battle for a hack-free crypto space is far from over.
