Kaspersky GReAT found a new UEFI bootkit, BlackX, used in early 2026 against diplomatic organizations in Tajikistan, Uzbekistan and Turkmenistan and attributed with medium confidence to China-linked APT41. It is a copycat of BlackLotus and exploits Baton Drop (CVE-2022-21894) to install its own Machine Owner Keys, load arbitrary EFI files and inject a kernel driver that blinds security software. The targeted machines were fully patched: Microsoft's fix only revokes the vulnerable "Windows Production PCA 2011" signing certificate after an admin manually sets a registry flag under HKLM\SYSTEM\CurrentControlSet\Control\Secureboot and runs the Secure-Boot-Update task, and Microsoft's planned automatic enforcement phase has not shipped. The certificate expired on Oct 19, 2026, but that does not stop vulnerable boot binaries from loading unless it is in the DBX blocklist. Attackers need admin rights or physical access first, so this is a persistence tool, not an initial access vector. Windows admins should apply Microsoft's Secure Boot revocation steps manually.
Fixed in
Protection requires manually enabling Microsoft's Secure Boot revocation (registry flag plus the Secure-Boot-Update scheduled task); see Microsoft's Boot Manager revocation guide, Microsoft's automatic enforcement phase has not shipped yet

Report URI and iVerify found criminals using 660+ re-registered expired analytics and ad-tag domains (DeadTag), hacked PrestaShop stores and a malicious Instagram ad to silently serve the Coruna (iOS 13 to 17.2.1) and P7 DarkSword (iOS 18.4 to 18.7) exploit kits. Opening an affected page on a vulnerable iPhone is enough; the spyware steals keychain passwords, crypto wallet data and device info. Updated iPhones are protected, so update iOS (or turn on Lockdown Mode if you can't).

2026-10-22: Report URI detailed the DeadTag operation: 660+ re-registered expired tag domains still loaded on thousands of sites (an estimated 135 million visits a month), selling visitor traffic to buyers including a Chinese-speaking crew that serves Coruna and DarkSword from a fake Polymarket page. The crew's DarkSword loader was also found on hundreds of hacked PrestaShop stores. (source)

ISC disclosed a remotely exploitable memory-corruption bug in BIND 9's named on Oct 21. An attacker who captures a GSS-TSIG signed UDP message (the Kerberos signing used for Active Directory-style dynamic DNS updates) can replay it while the negotiated key is still valid and, combined with crafted queries to a zone they control, may get remote code execution, or at least crash named. CVSS 8.1 (High). No workaround. Affects BIND 9.11.0 through 9.18.50, 9.20.0 through 9.20.29 and 9.21.0 through 9.21.26. Fixed in 9.20.30 and 9.21.27; ISC lists no 9.18 fix. ISC knows of no active exploitation. Debian trixie has a fixed package; Debian bookworm and Ubuntu are still waiting.

Storybook disclosed CVE-2026-114125 on Oct 21 2026: the dev server's preview iframe could be embedded by any website and accepted postMessage events from any origin. A malicious site open in the same browser could, with some user interaction, make a running `storybook dev` server change story files in your project, and a changed file could then be executed by a local runtime with your privileges.

Built (static) Storybooks are not affected.
2026-10-22: Closed on pwn.watch: fixes are out for every affected major and there is no known exploitation. Upgrade Storybook (and the Visual Tests addon to 5.5.1+ if you use it) and don't run an old dev server meanwhile. (source)
