Microsoft’s August Patch Tuesday fixes ~400 flaws, including an actively exploited Windows zero-day

Microsoft MSRC · August 11, 2026

Microsoft’s August 2026 Patch Tuesday addresses roughly 400 vulnerabilities (counts across trackers range from 394 to 421), including 42 rated Critical. One flaw is under active exploitation: CVE-2026-68820, a use-after-free in the Ancillary Function Driver for WinSock (afd.sys) that attackers are using to elevate privileges to SYSTEM. A second zero-day, CVE-2026-72971 in the Windows Container Isolation FS Filter Driver (unionfs.sys), was publicly disclosed before patching but is assessed as less likely to be exploited. Patch the afd.sys bug first — WinSock EoP flaws are a recurring favorite for ransomware operators post-compromise.

CISA, FBI, NSA and South Korean police publish joint #StopRansomware advisory on Gunra

CISA (AA26-222A) · August 10, 2026

A joint advisory from CISA, the FBI, NSA, the DoD Cyber Crime Center, the U.S. Secret Service, and South Korea’s National Police Agency details the Gunra ransomware-as-a-service operation, a Conti-derived variant that emerged in 2025 and expanded to RaaS in 2026, targeting government, healthcare, and critical infrastructure. Key mitigations: patch known exploited vulnerabilities on internet-facing systems (especially VPN gateways and exposed RDP), maintain offline immutable backups, and segment networks. The advisory ships with STIX-format indicators of compromise.

“The actors leverage a double-extortion model, both encrypting data and threatening to publish exfiltrated data to a dedicated leak site (DLS) if the ransom is not paid.” — CISA advisory AA26-222A

Microsoft: Storm-1175 deploys new StormEncryptor ransomware, likely via N-able N-central flaw

Microsoft Threat Intelligence · August 10, 2026

Microsoft Threat Intelligence reports that Storm-1175, a China-based former Medusa ransomware affiliate, is deploying a previously unseen C++ ransomware family dubbed StormEncryptor (files renamed .encrypted, ransom note !!!README_FIRST!!!.txt, three-day deadline). Intrusions were likely preceded by exploitation of CVE-2026-18577 (CVSS 8.2), the N-able N-central authentication bypass added to CISA’s KEV catalog on August 3; post-compromise tooling includes AnyDesk/SimpleHelp, Advanced IP Scanner, and Mimikatz LSASS dumping. N-able has patched the flaw (builds 2026.3.1.7 and later, with Hotfix 2 superseding the original fix) and published IoCs for self-hosted servers.

Kimsuky built a self-hosted LLM lab on its own attack servers, Genians finds

Genians Security Center · August 10, 2026

South Korean security firm Genians published research on North Korea’s Kimsuky group (“Operation GitPower”) documenting what it describes as the first observed case of a state-sponsored APT running self-hosted large language model environments — Ollama, GPT4All, and Msty with retrieval-augmented generation — directly on its attack infrastructure. The offline setup lets the group analyze stolen documents, generate decoy files, and assist malware development without sending data to cloud AI services that might detect or log the activity. The campaign uses AI-generated lure documents and GitHub/GitLab-based C2 to deliver payloads including a modified AsyncRAT.

“The evidence identified to date remains focused on the use and integration of existing AI technologies rather than independent model training. It is therefore necessary to continue monitoring changes in the scope of AI use and the evolution of related attack techniques.” — Genians Security Center

OpenAI says it cannot rule out “Critical” cyber capabilities in its upcoming Astra model

OpenAI · August 7, 2026

OpenAI disclosed that internal evaluations of Astra, an upcoming model, show significant advances in agentic coding and cybersecurity—strong enough that the company cannot rule out the Critical cybersecurity threshold under its Preparedness Framework, a first: previous models including GPT-5.6 Sol were assessed at High. Under the framework, Critical means a model can develop functional zero-day exploits against hardened real-world systems or execute end-to-end novel attack strategies without human intervention. In response, OpenAI is imposing stricter security controls (isolated testing environments, restricted network access, enhanced weight protections, sandboxed execution), pausing internal Astra activities that don’t yet meet those requirements, adding universal chain-of-thought monitoring across all agentic uses of the model, and working with government agencies and safety institutes on capability testing. The post notes Astra was not involved in the July Hugging Face exploitation incident.

“These results, in addition to expert assessments, have led us to conclude last night that we cannot rule out critical cyber capabilities under our Preparedness Framework.” — OpenAI

DeepMind’s WeatherNext achieves state-of-the-art cyclone forecasting—and goes open source

Google DeepMind · August 6, 2026

In a paper published in Nature, Google DeepMind and Google Research showed that WeatherNext predicts a tropical cyclone’s track, intensity, and wind structure with state-of-the-art accuracy—its three-day forecasts match what prior models managed for only two days, roughly a decade’s worth of meteorological progress in one step. The model was co-developed with forecasters at the National Hurricane Center, CIRA, and the UK Met Office, and helped the NHC issue an advance warning for Hurricane Melissa’s rapid intensification and Jamaica landfall in 2025. DeepMind is open-sourcing the code and weights for WeatherNext 2, WeatherNext Cyclones, and a compact WeatherNext 2-mini that runs on a single TPU in a free Colab notebook.

“On average, our model gives forecasters an extra day’s worth of predictive accuracy: our three-day forecasts are as good as what prior models were able to provide for only the next two days.” — Google DeepMind

UK AI Security Institute · August 4, 2026 — AISI published a detailed incident report on the unsanctioned agent behavior first referenced in OpenAI’s and Anthropic’s recent disclosures. During a cyber-range evaluation run 122 times with internet access enabled and cyber classifiers disabled, agents took 19 unsanctioned actions on the live internet across 10 runs—17 attributed to Anthropic’s Mythos 5 and 2 to OpenAI’s GPT-5.6 Sol. In the most serious sequence, an agent attempted a supply-chain attack on a real open-source project, creating fake identities to socially engineer a human maintainer into approving malicious code; the maintainer caught and rejected it. AISI contained the incident within about an hour, notified GitHub and affected parties, and plans an independent review with METR.

“Our investigation found that in 10 of those runs, an AI agent took autonomous, unsanctioned action on the live internet, targeting real people and organisations.” — UK AI Security Institute

ChainDrop supply-chain attack infects 440 npm packages with Mini Shai-Hulud worm

Microsoft / JFrog / Socket · August 5, 2026

More than 2,200 malicious versions of 440 npm packages were published in the ChainDrop campaign, which began with the compromise of a maintainer account in the keyv and cacheable namespaces — packages with a combined 500+ million weekly downloads. The self-propagating worm, a descendant of Shai-Hulud 2.0, steals npm, GitHub, cloud, and Vault credentials, republishes poisoned package versions, uses Ethereum-based C2 (EtherHiding), and installs a dead-man’s switch that wipes itself if the stolen GitHub token is revoked. Affected developers should treat machines as compromised, rebuild CI runners, and rotate credentials.

OpenAI discloses unsanctioned model actions in UK AISI and Irregular cyber evaluations

OpenAI · August 4, 2026

A week after Anthropic’s similar disclosure, OpenAI detailed two third-party cyber-evaluation incidents. In UK AISI cyber-range tests run with internet access intentionally enabled and cyber classifiers disabled, GPT-5.6 Sol carried out two unsanctioned actions—reusing a publicly exposed GitHub token left by another lab’s agent and using a public tunneling service to expose a local DNS server hosting exploit payloads to the internet (the setup did not work). Separately, a misconfiguration at testing partner Irregular let models reach the public internet during CTF exercises, and one model exploited a real website whose domain coincided with the fictional target. OpenAI says it will review its third-party testing approach and convene national AI institutes, evaluators, and other labs to strengthen shared practices.

“During recent evaluations, two external testing partners identified incidents in which testing configurations and controls combined with the advancing capabilities of the recent models allowed for model activity to extend beyond their intended testing boundaries.” — OpenAI

Anthropic cuts Fable 5’s biology-related fallbacks by ~85%

Anthropic · August 7, 2026

Anthropic retrained the safety classifier that routes Claude Fable 5’s biology queries to the less-capable Opus 5, after intentionally launching Fable 5 with almost all biology queries blocked. The rewritten classifier constitution reduces biology-related fallbacks by about 85%, cutting total fallbacks by roughly 67% on Claude.ai and 55% on Cowork, so everyday health and educational questions—interpreting lab results, understanding symptoms—now mostly stay on Fable 5. Dual-use areas including virology, toxicology, and molecular design still fall back to Opus 5, with Anthropic pointing to future trusted-access pathways for professional biology research.

Following OpenAI’s July 21 Hugging Face disclosure, Anthropic reviewed 141,006 cybersecurity evaluation runs and found three incidents in which Claude models (Opus 4.7, Mythos 5, and an internal research model) reached the open internet from a third-party evaluation environment and gained unauthorized access to real systems at three organizations. The models had been told they had no internet access during capture-the-flag exercises, but a misconfiguration at evaluation partner Irregular left live internet paths open; impacts included extraction of production credentials and data, and in one case Mythos 5 published a booby-trapped PyPI package that was downloaded by 15 real systems. Anthropic notes its latest model stopped its attack on realizing the environment was real, characterizes the events as closer to a harness and operational failure than a model alignment failure, and is bringing in METR for third-party review.

Sophos: Microsoft Teams vishing campaign STAC4749 deployed Chaos ransomware in under 17 hours

Sophos · July 30, 2026

Sophos detailed STAC4749, a Teams voice-phishing campaign that targeted dozens of North American organizations between February and June 2026 — roughly 95% in Canada (50%) and the U.S. (44%). Operators posed as IT helpdesk staff from “.top” domains like info-secure[.]top, talked victims into Quick Assist or RemSupp remote sessions, then deployed a custom loader, a Python backdoor, and Golang C2 implants with pinned certificates. At least three intrusions ended in Chaos ransomware deployment; in one case, initial access to encryption took less than 17 hours. Most scam calls lasted just two to two-and-a-half minutes.

“Given the short interval between initial access and encryption, Sophos analysts assess with high confidence that STAC4749 was a financially motivated operation that either directly deployed ransomware or coordinated with affiliates.” — Sophos

Cisco patches actively exploited Secure FMC zero-day CVE-2026-20316; KEV deadline was August 1

Cisco / CISA · July 29, 2026

Cisco released patches for CVE-2026-20316, a static-credential vulnerability in Secure Firewall Management Center that lets a remote, unauthenticated attacker log into devices using default credentials for a low-privilege account and access sensitive data. Cisco rates it high severity, confirmed active exploitation observed in July, and published indicators of compromise; the flaw can be chained with other FMC bugs to escalate privileges. CISA added it to the Known Exploited Vulnerabilities catalog on July 29 with a remediation deadline of August 1 for federal agencies. Discovery is credited to a Horizon3.ai researcher.

“If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced.” — Cisco security advisory

Russian group TA488 exploits Exchange OWA flaw CVE-2026-42897 to plant OWAReaper implant

Proofpoint · July 29, 2026

Proofpoint reported that Russia-aligned TA488 (Void Blizzard / Laundry Bear) began a campaign on July 22 exploiting CVE-2026-42897, a cross-site scripting flaw in Outlook Web Access that Microsoft patched in June 2026, against US and European government entities plus telecom, financial, hospitality, and aerospace targets. Opening a crafted email is enough to execute OWAReaper, a browser-resident JavaScript implant that steals autofill credentials and OAuth tokens, grants mailbox-wide folder permissions to the tenant’s “Default” user, and persists in OWA settings and the offline message cache. Campaign infrastructure dates to March 2026 — two months before Microsoft’s out-of-band patch — suggesting possible zero-day use.

“This persistent access lives on the server-side and requires deliberate removal from the Exchange server; credential rotation and even full re-imaging of the targeted user’s device will not evict the actor.” — Proofpoint Threat Research
