Weekly Cybersecurity Newsletter Bulletin – Microsoft 0-day, FortiOS, PAN-OS Flaw, Revolut Data Breach, and 20+ Stories
Weekly roundup: Microsoft patches 973 flaws including two actively exploited zero-days; FortiOS CAPWAP flaw deploys PivotC2 RAT; PAN-OS root RCE disclosed.
Microsoft's September 2026 Patch Tuesday fixed 973 vulnerabilities, including two zero-days under active exploitation: CVE-2026-85880 (Windows ALPC) and CVE-2026-81963 (Windows Update Stack), both elevation-of-privilege bugs. SOCRadar reported active exploitation of CVE-2025-25249 (CVSS 9.8) in FortiOS CAPWAP, deploying a Node.js RAT called PivotC2 that exfiltrates Exchange mailboxes to Wasabi cloud storage; 178 devices were compromised out of 30,000 scanned IPs, attributed to a Russian-speaking financially motivated group. Palo Alto disclosed CVE-2026-0310, a 9.2-rated buffer overflow enabling root code execution on PA-Series firewalls, and Fortinet disclosed CVE-2026-84393, a ZTNA certificate validation MITM flaw. Cyera also revealed CVE-2026-6471 ('PostGREShell'), a 12-year-old PostgreSQL logical-decoding flaw allowing code execution via REPLICATION-privileged accounts.
13 Malicious Packagist Packages Target Unpatched iPhones to Steal Crypto Wallet Seeds
Trojanized Packagist themes inject JavaScript into Vietnamese streaming sites, exploiting unpatched iPhone WebKit and kernel flaws to install spyware and steal crypto wallet seeds.
Socket researchers found 13 malicious Composer theme packages across five vendor namespaces (including vsmov, vsphim, and ophimcms) that inject JavaScript into Vietnamese movie and comic streaming sites. On iPhones running iOS 18.4-18.6.x, the injected code fires a WebKit-to-kernel exploit chain using CVE-2025-31277 and CVE-2025-43529, pivoting through the GPU process and the AppleM2ScalerCSCDriver IOKit user client to gain kernel read/write. Since around August 12, 2026 the payload also steals cryptocurrency wallet seeds and mnemonics from Bitget, BitKeep, Bitpie, Phantom, Tonkeeper, Trust Wallet, and OKX, alongside keychain databases, Wi-Fi passwords, SMS, photos, cookies, and location history, uploaded via HTTPS to rotating C2 domains. The group is believed to be Vietnamese-operated, hosts exploits on Funnull infrastructure, and Apple patched the kernel escape flaw in iOS and macOS 26.1.
