SingularityNET bridge keys abused after cloud breach: 8.72M FET released, billions of tokens minted
An unauthorized party got into part of SingularityNET's cloud infrastructure and on 19-20 September 2026 used a compromised authorizer signature and NuNet's mint authority to release 8.72M FET from a bridge and mint about 2.3 billion AGIX, NTX, WMTX and CGV. Sixteen wallets, four labelled as SingularityNET or NuNet staff, were swept before the minting. Headlines cited $16.77M, but Rekt's transaction-level count found about $2.29M in sellable proceeds because most minted tokens could not be sold. Bridges and converters are offline and AGIX is being replaced, so holders should wait for official migration steps.

Humanity Protocol loses $36M after malware on one developer machine exposes hot-wallet and Safe keys
On 8 June 2026 an attacker used private keys taken from a single malware-infected developer machine to seize Humanity Protocol's admin hot wallet and its Safe multisigs on Ethereum (three of six keys) and BNB Chain (three of five). They drained about 141M H tokens, used malicious bridge upgrades to mint hundreds of millions more and sold them, a loss of more than $36M; H fell about 89% from its high. The team halted bridge deposits and withdrawals and told users not to touch the bridge or liquidity pools.

IoTeX ioTube bridge drained of about $4.4M after attacker abused a compromised employee machine
On 21 February 2026 an attacker who had compromised an IoTeX employee's machine, reportedly through social engineering, upgraded the ioTube bridge's Ethereum-side Validator contract to a malicious version. That let them drain about $4.4M in bridge reserves (WBTC, ETH, USDC, USDT, DAI and others) and mint 410M CIOTX. IoTeX froze about 45M IOTX in attacker wallets, paused its chain for three days and opened a claims portal for affected users.
