Key Takeaways
- A crucial safety vulnerability threatened all IBC-enabled blockchains, Cosmos builders not too long ago found.
- The assault vector was found following final week’s BNB Chain’s exploit.
- A patch has already been communicated privately to Cosmos builders and validators.

Final week’s BNB Chain assault led Cosmos builders to examine their IBC code. They discovered a crucial safety vulnerability that endangered each IBC-enabled blockchain.
Cosmos Compromised
It seems your entire Cosmos ecosystem was endangered by a single vulnerability.
In response to an announcement posted right now within the Cosmos Hub governance discussion board by co-founder Ethan Buchman, lead builders not too long ago found a “crucial safety vulnerability that impacts all IBC-enabled Cosmos chains, for all variations of IBC.”
Cosmos is a decentralized community of blockchains related via the Inter-Blockchain Communication protocol (IBC), which allows customers to hop from one Cosmos blockchain to a different seamlessly. On the time of writing, there are 42 IBC-enabled blockchains, together with Cosmos Hub, Osmosis, Cronos, and Evmos. In response to the venture’s web site, the market capitalization of all IBC-enabled chains collectively reaches $8.18 billion.
Different main blockchains corresponding to OKX Chain, Luna Traditional, and Thorchain have additionally built-in IBC prior to now. For numerous causes, nevertheless, they’ve both deactivated the operate or by no means absolutely enabled it within the first place. BNB Chain is one in every of these initiatives. The current assault in opposition to it (throughout which a hacker drained $566 million from the blockchain’s bridge) incentivized Cosmos builders to analysis whether or not different IBC blockchains could also be susceptible to the identical exploit.
Buchman acknowledged that measures had already been taken to patch main IBC blockchains. The patch was first made accessible privately to present builders and validators the time to replace their chains earlier than the vulnerability was publicized. In response to him, greater than a 3rd of a blockchain’s voting energy should apply a patch for the venture to be secure. The Cosmos SDK will launch a public model of the patch on October 14 at 14:00 UTC. Buchman suggested all Cosmos chains and validators to improve to the general public patch as quickly as potential, even when they’d already built-in the personal patch.
Disclosure: On the time of writing, the writer of this piece owned BTC, ETH, ATOM, OSMO, and a number of other different cryptocurrencies.
