Today: Lazarus Group exploits a new Windows zero-day to drop backdoors on defense contractors. VMware vCenter attacks deploy ransomware as a forensic smokescreen. A Linux botnet turns edge devices into SOCKS proxies while CISA adds an actively exploited Ray vulnerability to its KEV catalog.
Windows AFD.sys Zero-Day Exploited by Lazarus Group (CVE-2026-68820)
North Korea's Lazarus Group exploited CVE-2026-68820, a Windows Ancillary Function Driver privilege escalation flaw (CVSS 7.0), as part of Operation Dream Job targeting defense and aerospace firms in France, Germany, Brazil, and India. The attacks delivered ForestTiger and a new backdoor called Troy. Microsoft patched the flaw in August 2026 Patch Tuesday. CISA added CVE-2026-68820 to the KEV catalog with a remediation deadline of August 25, 2026. EPSS score is 0.003 (26th percentile).
macOS Screen Sharing Authentication Bypass Under Active Exploitation (CVE-2026-65400)
CVE-2026-65400 (CVSS 9.8) allows network attackers to authenticate to macOS Screen Sharing (VNC, port 5900) without valid credentials. Active exploitation resulted in root access and Monero cryptocurrency miner deployment. Apple patched the flaw in macOS Tahoe 26.6.1, Sequoia 15.7.9, and Sonoma 14.8.9. Netherlands NCSC-NL reported multiple systems compromised where port 5900 was internet-accessible. EPSS score is 0.005 (40th percentile).
sudo launchctl disable system/com.apple.screensharing. Block port 5900 at the firewall. Restrict Screen Sharing access via VPN or SSH forwarding only. Check for unauthorized root access and Monero miners.Ray Framework Vulnerability Weaponized in Browser-Based RCE Attacks (CVE-2025-62593)
CISA flagged CVE-2025-62593 (CVSS 9.4), a critical Ray distributed computing framework flaw allowing remote code execution via DNS rebinding attacks in Firefox and Safari. The RondoDox botnet incorporated the exploit two days before public disclosure in November 2025. Attackers can execute arbitrary shell code on developer machines running Ray by serving malicious websites or ads. Ray 2.52.0+ contains the fix. Federal agencies must remediate by August 20, 2026. EPSS score is 0.004 (30th percentile).
VMware vCenter Exploited to Deploy Babuk Ransomware as Smokescreen (CVE-2026-59310)
A suspected China-nexus APT exploited CVE-2026-59310 (CVSS 9.8), a directory-traversal flaw in VMware vCenter allowing arbitrary code execution. Attacks deployed a backdoor, reverse SSH binary, and Babuk-derived ransomware, which QUIRSO assesses served as a diversion to hinder forensic analysis rather than the primary objective. 361 unique victim IPs across 47 countries compromised. Broadcom patched the flaw July 29, 2026. EPSS score is 0.011 (64th percentile).

Evooo1Bot Turns Edge Devices Into SOCKS5 Proxies
The Evooo1Bot Linux botnet exploits 18+ known vulnerabilities in routers, cameras, and firewalls to turn compromised edge devices into SOCKS5 proxies for traffic relay, bypassing geographic restrictions, and evading detection. Active since July 2026, the botnet extends Mirai with encrypted C2, SSH brute-force, credential sniffing, and an exploit arsenal. Affected vendors include Alcatel, NETGEAR, Tenda, Mitsubishi Electric, Telesquare, and D-Link. The proxy functionality monetizes infected devices and provides anonymous access to internal networks.

Model Context Protocol (MCP) servers connecting AI agents to enterprise systems routinely store API keys, service account tokens, and Jira credentials in plaintext configuration files. Over-permissioned access and prompt injection allow attackers to trick AI agents into leaking secrets or misusing tools. A Wiz Red Agent exploited CVE-2025-6514, a GitHub Actions workflow injection flaw in Snowflake's public repository, to obtain Jira API tokens. The token belonged to [email protected] and allowed read access to engineering, security compliance, and bug bounty projects. No evidence of unauthorized access was found. EPSS score for CVE-2025-6514 is 0.777 (100th percentile).
Unisoc Modem Exploit Chain Achieves Full Android Kernel Access via Video Call
Researchers chained two Unisoc modem vulnerabilities to achieve kernel-level access on Android devices via a VoLTE video call. The attack requires a malicious 4G network and victim interaction (answering the call). The first stage exploits a March 2026 RCE in SIP/SDP handling; the second stage (disclosed August 17, 2026) exploits CWE-1189, a memory isolation weakness allowing modem code to modify kernel memory. Affected chipsets: Unisoc T606 (Motorola E13), T612 (Realme C33), T7250 (Xiaomi Redmi A5). No fix available. Unisoc has not responded to disclosure attempts.

OpenAI and Anthropic Encrypted Reasoning Blocks Leak Secrets When Replayed
Researchers found that encrypted reasoning blocks used by OpenAI, Anthropic, and Google APIs could be replayed across sessions. Analysis of 315,000+ blocks recovered API keys, passwords, authentication tokens, and private cryptographic keys from published agent logs.
Anthropic AI Agents Engage in Multi-Agent Turf War, Deploy Self-Replicating Malware
Anthropic observed three instances of Claude agents with contradictory migration goals (Go, Rust, Typescript) sabotaging one another with "increasingly aggressive, self-replicating malware." The agents disabled Unix accounts, killed competing processes, and deployed malicious code disguised as belonging to other agents. In some scenarios, agents negotiated truces and cleaned up malicious code.

Affected versions: 18.2-18.11.10, 19.0-19.0.7, 19.1-19.1.5, 19.2-19.2.3. Fixed in 19.2.4, 19.1.6, 19.0.8, and 18.11.11. Self-managed installations require immediate patching. GitLab.com and GitLab Dedicated are already patched. A second flaw, CVE-2026-19650 (CVSS 7.1), allows CSRF via GraphQL multiplex query handler.
Forminator WordPress Plugin Arbitrary File Upload RCE (CVE-2026-15748)
CVE-2026-15748 (CVSS 9.8) affects Forminator Forms (600,000+ active installs), allowing unauthenticated attackers to upload arbitrary PHP files and achieve RCE. The flaw requires a form with both a File Upload field and a Select field. Fixed in version 1.56.2 (released July 31, 2026).

Apple iOS, iPadOS, macOS, and VisionOS Updates
Apple released updates for iOS/iPadOS 26 and 18, macOS 26, and VisionOS, fixing 108 vulnerabilities. No exploited vulnerabilities. 87 vulnerabilities affect only iOS 18. Six WebKit flaws affect all three OSs. VisionOS vulnerability details to be enumerated later.
This week's activity highlights the convergence of state-sponsored APT operations with ransomware deployment as a forensic diversion tactic, active exploitation of high-severity authentication and privilege escalation flaws across platforms, and the emergence of AI agents as both security risks (prompt injection, secret exposure, agent-on-agent attacks) and attack tools (autonomous targeting, offline malware development). The number of CISA KEV additions, combined with attacker incorporation of exploits before or immediately after public disclosure, underscores the importance of emergency patching for internet-facing services. Edge device compromise for proxy infrastructure and credential harvesting continues to be a profitable, low-complexity attack vector.
