Hacked Event Broadcast

Description of the event: Multiple suspicious transactions involving proxy contracts were detected on Arbitrum (ARB), with estimated losses of approximately $1.5 million. Preliminary analysis indicates that the sole deployer of the USDGambit and TLP projects may have lost access to their account. Subsequently, the attacker deployed a new contract and updated the ProxyAdmin permissions to seize control. The stolen funds were then bridged to the Ethereum network and deposited into Tornado Cash.

Description of the event: The Unleash Protocol project deployed on Story Protocol suffered an unauthorized contract upgrade, followed by the malicious transfer of user assets. The attacker manipulated the project’s multisig governance privileges to perform the upgrade, resulting in the theft and cross-chain transfer of assets including WIP, USDC, WETH, stIP, and vIP to external addresses. The currently confirmed loss is approximately USD 3.9 million. Unleash has suspended all operations and initiated a full investigation and audit process, urging users to refrain from interacting with its contracts. Story Protocol itself remains unaffected.

Description of the event: The Flow Foundation announced that an attacker exploited a vulnerability in the Flow execution layer, transferring approximately $3.9 million in assets off the network before validators were able to coordinate and halt operations. The incident did not affect existing user balances, and all user deposits remain intact.

Description of the event: Trust Wallet has issued an official notice confirming that version 2.68 of its browser extension contains a security vulnerability, and advised all users running version 2.68 to immediately disable it and upgrade to version 2.69. According to SlowMist’s analysis, this backdoor incident originated from a malicious modification of Trust Wallet’s internal codebase (analytics service logic), rather than the introduction of a compromised third-party package (e.g., a malicious npm package). The attacker directly tampered with the application’s own code, using the legitimate PostHog library to redirect analytics data to a malicious server. As of December 31, the incident has been confirmed to affect 2,520 wallet addresses, with a total loss of approximately USD 8.5 million. Preliminary investigation indicates that this attack is related to the Sha1-Hulud industry-level supply chain incident that occurred in November. Trust Wallet has now rolled back the extension to the secure version 2.69 and initiated a compensation process for affected users.

Description of the event: On December 14, Aevo announced that a vulnerability introduced during a smart contract upgrade led to an attack on the legacy Ribbon DOV vault on December 12, resulting in losses of approximately $2.7 million.

Description of the event: According to PeckShieldAlert, the stablecoin project USPD has suffered a major security breach, resulting in approximately $1 million in losses. The USPD team later confirmed that the protocol had been exploited, with the attacker minting tokens without authorization and draining liquidity. The official team has urgently advised users to revoke all token approvals granted to the USPD contract. According to the project’s confirmation, the incident was identified as a “CPIMP” attack. During the deployment phase, the attacker used Multicall3 to preemptively initialize the proxy and seize administrator privileges, while disguising the malicious implementation as an audited contract. The hidden logic remained dormant for several months before being activated, allowing the attacker to upgrade the proxy, mint approximately 98 million USPD tokens, and transfer around 232 stETH. The USPD team has disclosed the attacker addresses (Infector: 0x7C97…9d83, Drainer: 0x0833…215A) and stated that they are working with law enforcement and white-hat partners to trace the funds. The team has also offered a 10% bounty if the attacker returns the stolen assets.
