The Ontology mainnet has suspended block production due to a security review, and user assets have not been affected

According to the Ontology blog, its core development team discovered potential security vulnerabilities during routine security checks. Due to a high emphasis on the security and integrity of the mainnet, Ontology has immediately suspended block production on the Ontology mainnet to allow the technical team and validators to conduct a comprehensive security review of the network and related components. Ontology stated that no security incidents have been confirmed at this time, and there are no indications that user assets have been lost or stolen. ONT, ONG, and other on-chain assets are currently assessed to be unaffected; this suspension is a preventive security measure rather than a response to confirmed asset losses or ongoing attacks.During the review period, block production will remain suspended, and on-chain transactions cannot be processed. Users do not need to transfer or take any action regarding their ONT, ONG, and other on-chain assets, but should avoid conducting time-sensitive on-chain transactions until the network officially confirms its restoration. The duration of the suspension has not yet been determined, and the team will prioritize the comprehensiveness of the security review over speed; block production will not resume until the network has been thoroughly assessed and confirmed to be secure. The Ontology team is collaborating with validators and ecosystem partners to address this matter and will update progress through official channels, with a separate announcement to be made before and after the network restoration.

Coldcard releases new firmware to enhance security; affected users need to regenerate their mnemonic phrases and migrate their assets

Coldcard has released the latest firmware 5.6.1 (Mk4/Mk5) and 1.5.1Q (Q). This update is based on a three-week security review following an emergency fix, focusing on addressing the security risks posed by previous mnemonic phrase generation attacks. Each newly generated mnemonic phrase must include at least one user entropy source, such as irregular key presses at least 65 times, physical dice rolls 50 times, or physical coin tosses 128 times, combined with fresh entropy provided by STM32 TRNG, SE1, and SE2.The new firmware also adds pre-signing phased PSBT verification, strengthens USB connection and firmware update boundaries, improves Delta Mode isolation mechanisms, fixes active wallet backup issues, enhances random number generator initialization and fault checking, adjusts SIGHASH default settings, and includes multiple security and correctness improvements. Coldcard states that this update aims to further reduce the risk of the device being attacked.The official reminder is that updating the firmware cannot fix existing mnemonic phrases generated by previously affected firmware. If a user's mnemonic phrase falls within the scope of this security announcement, they should first update the device, then generate and verify a brand new mnemonic phrase, and migrate funds to the new wallet. Coldcard recommends that all Mk4, Mk5, and Q users update their devices promptly and verify the signatures of the downloaded firmware.
