A Cosmos EVM flaw let an attacker inflate Nesa balances and bridge $50M in NES, but thin liquidity limited the apparent profit to about $60,000.
Cosmos Labs warned EVM-compatible networks running on its infrastructure to pause block production immediately following a security incident. The company did not identify the affected networks, did not confirm whether any funds were stolen, and did not specify whether the cause was an exploit, a bug, or a configuration failure.
Cosmos Labs teams are responding to an ongoing incident affecting the Cosmos EVM module. Affected Cosmos EVM chains have been advised to request validator halts as the investigation continues.
Multiple Cosmos EVM chains faced different levels of disruption as teams worked to contain the shared security issue.
Several blockchain networks utilizing the Cosmos EVM infrastructure were compelled to suspend their operations in late August 2026 after Cosmos Labs detected an active security compromise affecting its core module.
Cosmos Labs urged EVM chains to halt as incidents hit MANTRA, TAC and KiiChain, with a detailed Cosmos report still pending.
The recurring security breaches highlight systemic vulnerabilities in blockchain interoperability, risking trust and stability in decentralized networks. Cosmos Labs warns of security incident affecting Cosmos EVM module users.
MANTRA Chain has successfully restored network operations following a comprehensive security patch that addressed a critical vulnerability in its Cosmos-EVM module, which forced the blockchain offline for approximately 30 hours.
MANTRA Chain has resumed block production after deploying version 8.4.0 to fix a Cosmos-EVM vulnerability that kept its mainnet unable to process transactions for about 30 hours. MANTRA Chain said in an Aug.
MANTRA halted its blockchain following an incident in its Cosmos EVM module that affected two wallet addresses and pushed its native token to a new all-time low. The team confirmed that user funds were not compromised and that the incident was contained before it could escalate. All endpoints, transactions, transfers, and staking operations are suspended while developers test the patched version v8.4.
The ATOM price has been battered so thoroughly that even historically important levels have failed to stop the decline. After reaching roughly $44 in 2021, ATOM spent the following years in a persistent downtrend, eventually falling to a new all-time low near $1.25 in 2026.
Social attention lifted ATOM, but exchange inflows could test that conviction.
