b14g: about 97M CORE drained from its Core staking contracts; contracts paused ยท updates https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026 On Oct 31 2026 at 09:29 UTC about 97M CORE staked through b14g, a Bitcoin dual-staking and yield protocol on the Core chain, was withdrawn without authorization and sent to attacker-controlled addresses, b14g said. It paused the affected contracts, says about 68M CORE remains on Core and exchange partners have frozen about 9M CORE linked to the attacker, and says BTC staked through b14g stays time-locked on Bitcoin and was not affected. Bitquery's on-chain analysis found one fresh wallet sent withdrawal requests for 0 CORE against 91 b14g staking orders it had never funded; Core's staking code treats 0 as the whole stake, so every order paid out in full (97.05M CORE, about $1.47M at the time). The pause came 66 minutes after the drain. Core DAO says the Core network itself was not compromised and CORE staked directly with validators or through other protocols is unaffected. b14g promises a post-mortem and next steps for affected users. Users have nothing to patch: don't restake through b14g until it publishes the post-mortem, and ignore unofficial refund offers. en Sat, 31 Oct 2026 17:24:00 GMT b14g: about 97M CORE drained from its Core staking contracts; contracts paused: Core DAO says the Core network is secure and CORE staked directly with validators or through other protocols is unaffected, and that it is helping trace and freeze the funds. https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026 https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026#2026-10-31-85e08607 Sat, 31 Oct 2026 17:24:00 GMT medium <p><a href="https://x.com/Coredao_Org/status/2116582149101121618">Source</a></p> b14g: about 97M CORE drained from its Core staking contracts; contracts paused: b14g confirms about 97M CORE was withdrawn without authorization, names two attacker addresses, says about 68M CORE remains on Core and about 9M is frozen by exchanges, and says staked BTC was not affected. https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026 https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026#2026-10-31-15b96dec Sat, 31 Oct 2026 16:38:00 GMT medium <p><a href="https://x.com/b14g_network/status/2116570456245596580">Source</a></p> b14g: about 97M CORE drained from its Core staking contracts; contracts paused: b14g's contracts are paused 66 minutes after the drain, by which time about 23.4M CORE has moved on through new addresses. https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026 https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026#2026-10-31-a9b2789c Sat, 31 Oct 2026 10:35:00 GMT medium <p><a href="https://bitquery.io/investigations/b14g-hack">Source</a></p> b14g: about 97M CORE drained from its Core staking contracts; contracts paused: A wallet funded half an hour earlier sends b14g withdrawal requests for 0 CORE against 91 staking orders it never funded; each order pays out in full, 97.05M CORE in total. https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026 https://pwn.watch/i/b14g-core-staking-zero-withdrawal-drain-oct-2026#2026-10-31-21e73a9d Sat, 31 Oct 2026 09:29:00 GMT medium <p><a href="https://bitquery.io/investigations/b14g-hack">Source</a></p>
