Nesa pauses services after a malicious exploit targets a Cosmos EVM vulnerability on its L1; team notifies exchanges and works on a software fix.
Security & Exploits ·
Nesa halted its services after a malicious exploit targeted a Cosmos EVM vulnerability on its Layer 1 blockchain. The team notified cryptocurrency exchanges of the incident and began developing a software fix to address the security flaw.
The exploit exposed a weakness in the EVM implementation running on Nesa's L1, which is built on Cosmos infrastructure. EVM compatibility allows Cosmos-based chains to support Ethereum-style smart contracts and applications, but the vulnerability created an attack surface that threat actors successfully leveraged. The pause in services was implemented as a containment measure while remediation efforts proceeded.
Details about the precise attack vector, the scope of affected user funds, and the timeline for service restoration remain unclear. The extent to which other Cosmos chains using similar EVM implementations may face comparable risks has not been disclosed.
