🔍 Researchers at the AI Now Institute demonstrated a proof-of-concept called "Friendly Fire" where autonomous AI coding agents (Anthropic's Claude Code and OpenAI's Codex) execute an attacker's binary when asked to scan untrusted open-source code. The attack hides a malicious binary alongside benign files and a README that prompts the agent to run a security script; in auto-modes the agents approved and executed it without prompting. The weakness is framed as a workflow/design issue rather than a single vulnerable version, and the researchers recommend never giving command-capable agents unattended access to untrusted code.

🔍 A pseudonymous researcher published an 'Exploitarium' GitHub repository containing over 30 proof-of-concept exploits for zero-day vulnerabilities in many open-source projects without prior vendor notification. The dump, shared from June 27 onwards, targets projects like libssh2, FFmpeg, 7-Zip, Gitea, PHP and others, and the author claims AI-assisted fuzzing using OpenAI models. The release bypassed coordinated vulnerability disclosure, drew debate across the security community, and has led to some CVEs and patches, while others remain under review.

🛡️ OpenAI has unveiled GPT-5.6 Sol, calling it its "most capable model yet for cybersecurity," but initial access is restricted to a small set of vetted partners at the request of the US government. The preview, announced on June 26, introduces three tiers—Sol, Terra and Luna—and is available via API and Codex to selected partners while OpenAI coordinates with the government on a cyber executive order framework. OpenAI says Sol excels at long-horizon tasks like vulnerability research, includes enhanced safeguards and real-time classifiers, and currently does not autonomously produce full exploits.

🛡️ OpenAI released three GPT-5.6 variants—Sol, Terra, and Luna—as a limited preview to select companies while engaging with the U.S. government. Sol is the flagship and most capable for cybersecurity work, Terra balances efficiency and power, and Luna is optimized for speed and cost. OpenAI emphasized strengthened safety controls, warned of potential legitimate-request blocks during preview, and plans a wider release in the coming weeks.

🔔 Push Security discovered a campaign where attackers create fraudulent OpenAI tenants impersonating real companies and send legitimate-looking invites to employees. The invites originate from OpenAI notification addresses, pass authentication checks, and assign recipients Owner privileges within the fake organization. Attackers used Gmail accounts to pose as company executives and even attached a billing card to the tenant, likely to reduce suspicion. Push Security warns employees could be tricked into submitting sensitive data into the workspace and advises verification and monitoring of SaaS memberships.

🔒 OpenAI has expanded its Daybreak cyber-defense program, advancing patch automation with the full release of GPT-5.5-Cyber, updates to Codex Security, and a new open-source patching initiative. Access to the model is limited to verified defenders and paired with enhanced monitoring. OpenAI reports improved vulnerability reproduction and exploit-writing scores, while emphasizing human oversight and partnerships with vendors and governments.

🔒 OpenAI has teamed with Trail of Bits to launch Patch the Planet, an AI-assisted vulnerability research program aimed at finding and fixing flaws in widely used open-source projects. The initiative pairs models and Codex Security with human review and established disclosure channels, and has already identified hundreds of issues and merged dozens of patches. Participants include projects such as Python, Go, cURL, Sigstore, and others that underpin enterprise software supply chains.

🔒 OpenAI is distributing an enhanced GPT‑5.5‑Cyber model to trusted defenders via the Daybreak program, claiming improved capability to find, validate, and patch software vulnerabilities across large codebases. The company also updated the Codex Security plugin to accelerate discovery, triage, and automated patch generation, and launched Patch the Planet with Trail of Bits to secure open‑source projects. These steps aim to help maintainers cope with the surge in AI‑driven vulnerability findings while preserving human oversight.

🤖 Check Point is embedding OpenAI frontier cyber models into its security products through the Daybreak Cyber Partner Program to deliver sharper prevention, faster remediation, and stronger security operations. The partnership emphasizes built-in guardrails, misuse monitoring, and task-focused outputs. Initial explorations target agentic network security orchestration and CTEM Agentic Exposure Validation to improve policy translation, configuration validation, exposure summarization, prioritization, and remediation drafting.

🔬 OpenAI appears to be testing a new subscription called "ChatGPT for Science" spotted on the web build, aimed at scientific use cases. It may join existing offerings—Personal, Teams, and Business—and could be restricted to verified institutes or universities. OpenAI has previously developed specialized models like GPT-Rosalind for enterprise life sciences, suggesting advanced capabilities and stricter access controls.

🔒 Check Point announced it has joined OpenAI’s Trusted Access for Cyber (TAC) program and the Daybreak initiative to access advanced cyber-capable models.

🔒 OpenAI’s Lockdown Mode aims to reduce AI-enabled data exfiltration by disabling web browsing, image support, Deep Research, Agent Mode, network access from generated code, and file downloads while still permitting manually uploaded file analysis. Experts say the feature is a pragmatic but imperfect mitigation that still allows side-channel exfiltration, complicates governance across multiple AI vendors, and shifts responsibility between providers and enterprise security teams.

🔒 OpenAI has rolled out two new security controls for ChatGPT: Lockdown Mode and Active Sessions. Lockdown Mode restricts outbound network access to prevent data exfiltration via prompt injection, at the cost of disabling live connectors and certain features. Active Sessions gives users visibility into and control over signed-in devices, with the ability to end single or all sessions. Both controls target account security and sensitive-data use cases, though SSO accounts and some logins remain unsupported.

🔒 Microsoft will delay automatic extension updates in Visual Studio Code by two hours to reduce exposure to potentially compromised releases. The feature, available in VS Code 1.123, allows immediate manual updates via the "Update" button and shows reasons and scheduled times for pending updates. Trusted publishers such as Microsoft, GitHub, and OpenAI are exempt and continue to update immediately. The change follows similar cooldown controls added across package managers to curb software supply chain threats.

🔎 OpenAI proposed mandatory federal evaluations for the most capable AI models before public release while arguing regulators should not have authority to approve or block deployments. The company urged pre-release assessments by the Center for AI Standards and Innovation (CAISI) alongside audits, transparency reports, incident reporting, and whistleblower protections. OpenAI framed this approach as a middle ground that enhances government visibility and preserves developer responsibility for release decisions.

🔍 At Infosecurity Europe 2026, Bugcrowd unveiled ExploitBench, a graded benchmark assessing AI models' ability to chain vulnerability discovery into staged exploits against a vulnerable V8 build.
