CVE-2026-82435: Apache Storm Worker: Unauthenticated Remote Memory Exhaustion in the Worker Messaging Decoder

Unauthenticated remote memory exhaustion in Apache Storm Worker 3.0.x Netty decoder fixed in 3.1.0, allowing pre-auth denial of service.

CVE-2026-82435 (rated important) affects Apache Storm Worker (org.apache.storm:storm-client) versions 3.0.0 before 3.1.0. The worker's Netty message decoder sits ahead of SASL authentication handlers and processes frames before any authentication occurs. It allocates buffers sized from an attacker-controlled length field, so a single frame from an unauthenticated peer reaching the worker can exhaust memory. Users must upgrade to 3.1.0.

CVE-2026-82430: Apache Storm Worker Launcher: Local Privilege Escalation to Root via Container Command Files Chowned to the Tenant

Setuid-root Apache Storm worker-launcher chowns worker directory to the tenant before reading its command file, enabling local root privilege escalation.

CVE-2026-82430 affects Apache Storm Worker Launcher (org.apache.storm:storm-core) versions 3.0.0 before 3.1.0, rated important. When launching Docker or OCI workers, the setuid-root worker-launcher transfers ownership of the entire worker directory to the untrusted topology user before reading and acting on the supervisor-written command file in that directory. An untrusted tenant can tamper with the command file to achieve local privilege escalation to root. Fixed in version 3.1.0.

CVE-2026-82429: Apache Storm Worker Launcher: Local Privilege Escalation to Root via a Time-of-Check Race in the Worker Launcher

Apache Storm's setuid-root worker-launcher re-resolves paths during recursive chown/chmod, letting local users win a race to escalate to root.

CVE-2026-82429 affects Apache Storm Worker Launcher (org.apache.storm:storm-core) versions 3.0.0 before 3.1.0, rated important. The setuid-root worker-launcher walks worker directories with FTS calling lchown and chmod on full pathnames while running with effective uid 0, and both syscalls re-resolve the path at call time. A local attacker can exploit this time-of-check race by swapping path components to gain root privileges. Fixed in version 3.1.0.

Attackers Use Passkey Phishing to Hijack Microsoft Cloud Accounts and Exfiltrate Data

Microsoft details two campaigns: million-email CEO impersonation ACH fraud and passkey-themed vishing that hijacks Microsoft cloud accounts for data theft and extortion.

Microsoft disclosed a campaign that sent over one million CEO-impersonation scam emails between August 3-5, 2026, targeting U.S. accounts payable departments with fake ServiceNow subscription invoices to induce ACH transfers, using generative AI to tailor templates. A second campaign detected since May 2026 uses passkey/MFA-themed voice phishing posing as the IT help desk, redirecting victims via SMS to counterfeit Microsoft sign-in pages and adversary-in-the-middle or device-code flows to hijack accounts. Post-compromise activity includes adding attacker-controlled authentication methods, high-volume Microsoft Graph activity, SharePoint and OneDrive downloads, and mailbox collection via REST APIs. Microsoft attributes initial access to Storm-3121 (linked to ShinyHunters and Falcon extortion) and Storm-3032 (UNC6671, a BlackFile splinter operating the Helix extortion brand).

Passkey-themed phishing attacks lead to Microsoft 365 data theft

Microsoft links ShinyHunters- and Helix-affiliated actors to passkey-themed vishing and device-code phishing that compromises Microsoft 365 accounts and steals cloud data.

Microsoft attributes passkey- and SSO-themed social engineering activity, observed since May 2026, to Storm-3121 (linked to ShinyHunters and Falcon) and Storm-3032 (tied to BlackFile members now operating as Helix). Attackers impersonate corporate IT help desks by phone or SMS, urging fake passkey, MFA, or SSO updates and directing victims to adversary-in-the-middle phishing pages or device-code authentication flows that yield credentials, session tokens, and OAuth tokens. Post-compromise behavior includes Microsoft Graph enumeration of users, SharePoint, and OAuth grants, plus persistence via attacker-controlled MFA methods. Google Threat Intelligence tracks related activity as UNC6671, linked to the BlackFile, Helix, Falcon, Pink, and Redact extortion gangs.

Anthropic caught Russia-linked spies using Claude in hacking operations

Anthropic disrupted Russia-linked APT29 using Claude in espionage against 20+ organizations, including Ukrainian government targets and a military drone maker whose vision SDK was stolen.

Anthropic's threat report covering December 2025 to August 2026 attributes the campaign to Midnight Blizzard (APT29/Cozy Bear, Storm-2945), which it links to Russia's SVR. The group compromised hotel Wi-Fi providers, altered DNS records to redirect travelers, accessed mailboxes at two drone-component manufacturers, and stole a proprietary SDK for a drone vision system, which it reverse-engineered using Claude. The group also used Claude to monitor whether security products detected its implants and to modify and redeploy flagged artifacts. The report also covers ShinyHunters affiliates using AI for credential scanning and extortion, a Chinese-speaking group's autonomous zero-day research, and a French-speaking hacktivist.

Detect and disrupt AI-themed attacks with Microsoft Defender

Microsoft Threat Intelligence reports criminal campaigns impersonating ChatGPT, Copilot, Claude, and DeepSeek in phishing, AiTM, and malvertising attacks reaching 100,000 emails daily.

Microsoft Threat Intelligence observed a growing set of campaigns that abuse trust in popular AI brands: a ChatGPT-themed phishing campaign sent up to 100,000 emails in one day to steal payment card data, and a Claude-themed campaign used adversary-in-the-middle techniques to harvest credentials and access tokens. Other campaigns included malvertising for a fake AI Windows plugin delivering the Vidar stealer and fraudulent DeepSeek installers distributed via GitHub. Initial access broker Storm-3075 used AI-themed malvertising to distribute payloads for multiple downstream actors, and Microsoft notes the AI services themselves were not compromised. Microsoft also details Defender protections such as Safe Links, Safe Attachments, and attack disruption against these multi-stage lures.
