Alby Hub Critical Flaw Could Let Attackers Take Over Internet-Exposed Bitcoin Wallets

Alby warns a critical flaw in internet-exposed Alby Hub Bitcoin wallets (v1.7.0–v1.18.5) could allow takeover and fund theft; update to v1.24.0.

Alby disclosed a critical flaw in Alby Hub, its self-hosted Lightning wallet, affecting versions v1.7.0 through v1.18.5 when the management interface is reachable from the internet. The flaw could let attackers take over a wallet and send its funds; one affected user has been reported so far, with no word on losses. Versions v1.19.0 and later contain the fix, and Alby advises updating to v1.24.0, binding port 8080 to localhost or firewalled sources, and changing unlock passwords on previously exposed hubs. Full technical details will be published later under responsible disclosure.

“Zero-click” WeChat worm could hijack accounts and spread via a single call

Researchers discovered a critical memory corruption flaw in WeChat's VoIP stack enabling a zero-click worm, WeWorm, that hijacks accounts via calls; Tencent patched it.

Calif researchers weaponized a memory corruption issue in WeChat's VoIP stack into "WeWorm", a worm that spreads through WeChat calls without user interaction, hijacks each victim's account, and propagates via saved contacts across iOS and Android, potentially reaching millions of devices within hours. Exploitation takes seconds and grants full account control, and chaining with other reported Android/iOS bugs could lead to full device control. Tencent issued updated WeChat versions for iOS and Android and applied server-side mitigations; technical details remain withheld. WeChat has over a billion users, overwhelmingly in China.
