Asymmetric Research, a security firm that contributes to the Wormhole interoperability protocol, disclosed details of a vulnerability impacting the Cosmos blockchain ecosystem that it says could have put more than $150 million at risk.
"We privately disclosed the vulnerability through the Cosmos HackerOne Bug Bounty program and the issue is now patched," Asymmetric said in a statement."No malicious exploitation took place and no funds were lost." A primary component of most Cosmos chains is the Inter-Blockchain Communication Protocol, or IBC – a technology that allows blockchains to easily communicate with one another and send assets back and forth. The vulnerability Asymmetric discovered was in ibc-go, a reference implementation of IBC used by a number of Cosmos chains.
