Ransomware Group Emperador Claims 3.9 GB Data Theft from AB InBev

The ransomware group Emperador has added AB InBev, the manufacturer of Budweiser and Corona beers, to its list of alleged victims. The group claims to possess 3.9 GB of internal data and is demanding a $1 million Bitcoin ransom. The listing includes 329,244 social listening alerts, 2,510 corporate emails from subsidiaries, around 19,000 access records, internal service portal logs, and public key infrastructure certificates. Most of the data volume, 3.2 GB, is attributed to Azure storage assets. AB InBev has neither confirmed nor denied the claims, and no samples have been published to verify authenticity. The announcement provides no details on how the data was allegedly obtained, such as an exposed storage account or leaked credentials. While access records and certificates could aid network mapping and lateral movement, the lack of private keys or confirmed encryption of systems limits the immediate impact assessment.

Automated Scans Exploit CVE-2026-39364 in Exposed Vite Dev Servers to Steal AWS and Azure Secrets

A large-scale automated campaign is actively scanning the internet for publicly exposed Vite development servers to exfiltrate sensitive files and cloud credentials. Attackers leverage CVE-2026-39364 to bypass server.fs.deny restrictions and read arbitrary files using crafted query parameters such as ?raw combined with ?import. The campaign has generated thousands of requests over several weeks, with telemetry from honeypots recording 807 sessions and roughly 32,000 events in a single month. Targets include .env files, terraform.tfstate, and other infrastructure-as-code artifacts that often contain AWS access keys and Microsoft Azure tokens. The vulnerable versions are Vite 7.1.0 through versions prior to 7.3.2 and Vite 8.x prior to 8.0.5. Part of the scanning traffic originates from Google Cloud IP ranges 34.x and 35.x. Organizations are urged to update immediately, restrict the dev server to localhost, and rotate any exposed cloud credentials.

Microsoft Addresses 973 Vulnerabilities in September Security Update

Microsoft released its monthly security updates on September 8, 2026, fixing 973 vulnerabilities tracked by CVE identifiers. The release coincided with Patch Tuesday and also resolved four third-party software flaws. Affected products span Windows, Office, SQL Server, Azure, Microsoft Dynamics, SharePoint Server, and various development tools. Among the issues, 258 allow remote code execution and 438 enable privilege escalation. A total of 113 vulnerabilities received the highest severity rating of Critical, while the remaining 860 were rated Important. Several of the flaws have already been observed in active exploitation.

Microsoft Releases Record 966 Patches in Largest Patch Tuesday Ever, Including Two Actively Exploited Zero-Days

Microsoft has issued its largest monthly security update to date, addressing 966 vulnerabilities across Windows and related products during the September Patch Tuesday. The release includes two zero-day flaws already exploited in real-world attacks: CVE-2026-81963 in the Windows Update stack and CVE-2026-85880 in the Windows ALPC mechanism, both enabling local privilege escalation to SYSTEM level. A total of 105 vulnerabilities received critical severity ratings, with the majority involving privilege escalation (438) and remote code execution (258). An additional 204 issues were fixed earlier in September across Azure, Entra ID, Edge, and other services. The surge in patched flaws coincides with Microsoft's deployment of an AI-assisted vulnerability discovery system. Previous months saw significantly lower volumes, with 570 fixes in July and 400 in August.

Widespread AI Outage Exposes Fragile Cloud Dependencies Behind ChatGPT, Claude and Grok

On September 3, major AI services including ChatGPT, Claude, Grok, Copilot and Gemini suffered a simultaneous outage lasting nearly four hours. The incident began around 9:30 a.m. ET with ChatGPT and rapidly spread, generating over 12,000 reports on Downdetector within twenty minutes. Industry analysis points to underlying cloud infrastructure rather than the models themselves, with Microsoft Azure and Cloudflare identified as the most likely points of failure. Developers relying on tools such as Cursor experienced immediate loss of code completion and intelligent assistance, forcing manual workflows. The event highlighted single points of failure created by heavy concentration of AI workloads on a small number of cloud providers. Security professionals are urged to map AI supply chains, prepare fallback procedures, monitor infrastructure status pages and adopt multi-vendor routing for critical operations.

Microsoft Patches Record 570 Windows Vulnerabilities in July Update, Including Three Actively Exploited Zero-Days

Microsoft released its largest Patch Tuesday update to date, addressing 570 vulnerabilities across Windows and related products. Among them are three zero-day flaws, two of which have already been exploited in real-world attacks. Fifty-nine issues were rated critical, with 48 enabling remote code execution. The company credited its use of AI for discovering more vulnerabilities in the Windows codebase. The update covers a wide range of components including .NET, Active Directory services, Microsoft Office, Azure services, and Microsoft Defender. Administrators are urged to apply the patches promptly to mitigate risks from privilege escalation, remote code execution, and information disclosure flaws.
