Cosmos Labs2026-09-30 02:34:50Cosmos Labs connects tokenization suite to Swift’s blockchain-based shared ledgerCosmos Labs said its tokenization suite has been connected to Swift’s blockchain-based shared ledger, giving banks a way to run tokenized deposit ledgers on Cosmos infrastructure while linking them to Swift and other external networks. The company said the system is built to work alongside existing bank core platforms, including Fiserv, FIS, Jack Henry, Temenos, and Hogan. Cosmos Labs also said its stack supports deployments on Ethereum Virtual Machine (EVM) environments and Hyperledger Besu, giving institutions flexibility in how they manage internal ledger technology. Under the setup, banks can keep their current ledgers in place while extending connectivity to Swift’s ledger, Canton, Partior, Ethereum, and Solana. The update was cited by Techub News, which attributed the report to Bitcoinist.900
Cosmos Labs2026-08-29 20:26:13Cosmos Labs says misjudged Cosmos EVM bug after six chains lost about $5.7 millionCosmos Labs said in a technical report that it had previously misjudged an integer underflow vulnerability in Cosmos EVM, a flaw later exploited across six blockchain networks between Aug. 20 and Aug. 25. The attacks resulted in roughly $5.7 million in stolen tokens, according to the report. The company said attackers used the bug to push an account balance down to the maximum value of 2^256-1 through underflow, then reversed the operation and transferred out the inflated balance. The report added that the exploit did not mint tokens out of thin air. A researcher first submitted the flaw through a bug bounty program on April 25, but testers could not reproduce it under the existing Cosmos chain configuration. Cosmos Labs said it issued a silent patch in May. After an independent researcher confirmed in early August that the issue affected all Cosmos EVM chains, Cosmos Labs released a patch on Aug. 19. The first attack followed about 20 hours later. Among the disclosed losses, MANTRA lost 720.9 million tokens, worth about $3.6 million. TAC lost nearly 3 billion TAC, while KiiChain lost about 148 million KII. MANTRA and KiiChain criticized Cosmos Labs for not notifying affected chains in advance and not recommending a shutdown.1110
Cosmos Labs2026-08-27 02:33:15Cosmos Labs urges older Cosmos EVM chains to halt and upgrade to patched releasesCosmos Labs said in a post that many chains affected by the current security incident have already completed patch upgrades. The team added that it will continue providing mitigation information to affected chains. It also urged any chain running a Cosmos EVM version lower than v0.6.2 or v0.7.2 to halt immediately and upgrade to a release that includes the patch. The statement was published through Cosmos Labs’ official X account and addressed operators of chains still using older versions during the ongoing incident. The update did not disclose additional technical details in the brief notice, but it made clear that patched versions are now the recommended path for chains still exposed under the version thresholds cited by the team.1090
TAC2026-08-26 10:48:22TAC delays post-incident report and recovery plan release in coordination with Cosmos LabsTAC, an L1 blockchain, said it has agreed with Cosmos Labs to hold back the release of its post-incident review and recovery plan for now. The delay is tied to a vulnerability involving Cosmos’ shared EVM module, which affects more than just TAC. According to TAC, Cosmos Labs asked for additional time so that all impacted networks in the Cosmos ecosystem can complete patching safely before the documents are made public. TAC said it fully agrees with putting ecosystem-wide security first and added that both the incident report and the recovery plan will be released soon. The update points to a coordinated disclosure approach, with the teams prioritizing patch completion across affected networks before publishing technical details.920
Cosmos Labs2026-08-24 22:54:45Cosmos Labs says ongoing security incident has affected Cosmos EVM usersCosmos Labs said an ongoing security incident has affected users of the Cosmos EVM module, according to a newsflash published by ChainCatcher. The company said its security and engineering teams are actively responding to the issue. It also said it has advised Cosmos EVM chains that are in contact with the company to ask validators to pause chain operations. Cosmos Labs thanked teams using Cosmos EVM for their quick response and said it will release an incident report after the matter is resolved. For teams using Cosmos EVM that have questions, the company said they can reach out via security@cosmoslabs.io. The update did not include further details on the nature of the incident.1120
