Crypto exploit losses fell sharply in December 2025 as PeckShield data showed reduced damage despite persistent attacks.
Crypto security risks eased notably in December as exploit-related losses declined sharply across markets. According to PeckShield, total losses reached $76 million during the month. Therefore, this figure showed a drop of more than 60% when compared with November figures, which means cautious optimism.
The December total was a large improvement from November losses of $194.27 million. However, security incidents did not go away entirely across the decentralized platforms. Instead, PeckShield reported about 26 major crypto exploits during the time, indicating ongoing threats.
PeckShieldAlert posted the data on its official X account on Thursday. Consequently, analysts viewed the report as an indication of better damage control and not fewer attacks. Therefore, security teams put faster detection and response measures in place.

The biggest singular loss in December was due to an address poisoning attack. In that incident, wallet address 0xcB80…819 lost about $50 million. Address poisoning Scams use lookalike addresses to deceive the user while transferring.
Another major breach was a compromised multisig wallet. According to PeckShield, address 0xde5f66b4800e965 was vacuumed of $27.3 million. The loss is said to have followed a private key leak, highlighting persistent key management vulnerabilities.
Beyond those attacks, a number of other attacks contributed to December losses. The resulting losses from babur.sol equaled $22 million. Meanwhile, Trust Wallet suffered damages amounting to $8.5 million during the same month.
Additional protocols also experienced fewer but significant breaches. Unleash Protocol lost $3.9 million. Similarly, Flow blockchain had losses of $3.9 million, as per PeckShield’s disclosure.
Collectively, these incidents made December’s top 5 exploit list. Therefore, the multisig breach was ranked first, amounting to $27.3 million. Babur.sol came next at $22 million and Trust Wallet came in third.
Address poisoning scams were an ongoing attack vector throughout December. Attackers created similar wallet addresses to fool people into sending money to the wrong address. As a result, analysts emphasized increased verification practices of transaction recipients.
In spite of reduced losses, PeckShield warned against complacency in the entire ecosystem. Instead, the firm stressed consistent vigilance with continuously refined techniques employed by attackers. Therefore, fewer losses can indicate improved controls, not less criminal intent.
The December improvement was in contrast to volatile conditions earlier in 2025. During several months, individual exploits caused over $100 million in damages. As a result, the $76 million total was one of the lowest month totals in the second half.
Security experts said better monitoring tools were partly responsible for the decline. Additionally, exchanges and wallets reportedly strengthened the filtering and alert systems for transactions. Therefore, the quicker the response, the greater the help to limit the success of attackers before further damage occurs.
Market participants responded with cautious optimism to the report. Lower losses of exploits may favor better confidence of users and developers. But experts cautioned that confidence is still fragile without continued security investment.
PeckShield said evolving methods of scam could easily overturn recent gains. Consequently, companies were encouraged to improve wallet interfaces and user education. Improved transparency and timely alerts are important defense measures.
Overall, the figures for December are encouraging – showing significant progress in mitigating exploit damage. However, PeckShield said attackers are still active and adaptive. As a result, continuous improvement is still required to continue decreased trends in losses.
