Gravity Bridge, a Cosmos-native cross-chain protocol, was the target of a 
compromised-key attack, which led to the theft of roughly $5.4 million over 
the weekend. This latest security breach joins the growing list of exploits 
suffered in the decentralized finance (DeFi) space so far in 2026. Gravity 
Bridge Hack Traced To Signing Key Compromise: Investigator On Saturday, May 
31st, blockchain sleuth Specter highlighted that Gravity Bridge might have 
been exploited through what he described as a signing key compromise. For 
context, a signing key compromise refers to the unauthorized disclosure or 
theft of a cryptographic key, allowing an attacker to then use it to decrypt 
sensitive information, forge digital signatures, or gain unauthorized access 
to systems and, as in this case, funds. Related Reading: AAVE Price Plummets 
By 26%: $9 Billion Net Outflows Traced To Kelp DAO Hack The analyst disclosed 
that the loot included crypto assets worth about $5..4 million, including $4.3 
million in USDC, 274 wrapped Ether valued at roughly $553,000, $434,000 in 
USDT, and 14.16 PAXG tokens priced at about $64,000. According to security 
firm PeckShield, the bad actor has laundered a portion of the stolen funds 
through the ChangeNOW and Binance exchanges, but still holds over 2,100 Ether 
(worth approximately $4.23 million). The team behind Gravity Bridge confirmed 
the attack on Saturday, saying that validators and orchestrators should halt 
their operations while they investigate the exploit. &#8220;Thanks to the swift 
action of validators, the bridge is currently halted while investigations 
continue,&#8221; the protocol announced in a subsequent post on social media post. 
Gravity Bridge is a cross-chain protocol that works by locking tokens on the 
Ethereum network and creating direct replicas of the crypto assets on the 
Cosmos network, relying on validator signatures to authorize each transfer. 
Hence, the protocol would treat even forged transactions as legitimate if a 
bad actor gets the appropriate signing keys. If confirmed as a key compromise, 
this Gravity Bridge incident would align with the ongoing pattern of crypto 
bridge attacks, in which breaches are typically embedded in access controls 
rather than in the underlying smart contract code. This pattern can be 
observed in the majority of the recent exploits, with Kelp DAO&#8217;s $292 million 
attack a notable incident. Crypto Hacks Continue To Pile In 2026 As mentioned 
earlier, Gravity Bridge&#8217;s $5.4 million hack joins the growing list of hacks 
that have rocked the crypto industry, especially the DeFi sector, in 2026. 
Specifically, bridges appear to have been a soft target for attackers in this 
period. Specifically, a TRM Labs report identified April 2026 as the most 
hacked month, with the highest number of incidents in crypto history. These 
attacks included the aforementioned $292 million Kelp DAO hack and Drift 
Protocol&#8217;s $285 million loss. Related Reading: Can Ripple’s Fed Master Account
