Anthropic security research: AI builds working Firefox exploits within 40 minutes of seeing the patch

Anthropic's security research team published findings on June 10, 2026 showing that Claude Mythos Preview, given 18 Firefox SpiderMonkey security patches, produced working proofs of concept for 14 of 18 vulnerabilities within 40 minutes, with the first arriving in 12 minutes, per the Anthropic Red Team report. In a separate test against the closed-source Windows kernel with no source code provided, Mythos Preview found 8 privilege-escalation chains. Opus 4.8 managed 11 of 18 Firefox CVEs. Publicly available models also demonstrated meaningful exploit-building capability, per the same report. The researchers wrote that "a lone operator can now turn a month's worth of patches into working exploits in a single afternoon, for a few thousand dollars and with no specialized expertise." Mozilla had not published a formal response to the shortened patch-window finding at time of writing. Full story: Anthropic Mythos Preview converted Firefox patches to exploits in 40 minutes

Anthropic files confidential S-1 with SEC for proposed IPO

Anthropic filed a confidential draft registration statement on Form S-1 with the U.S. Securities and Exchange Commission on June 1, 2026, per Anthropic's own announcement. The filing came roughly two weeks after Anthropic disclosed a $65 billion Series H round at a roughly $965 billion post-money valuation. No share count or offering price has been set, and the filing gives Anthropic the option to proceed with a public offering after SEC review. The SEC review process typically takes 30 to 90 days before a company can proceed to a roadshow. Full story: Anthropic files confidential S-1 with SEC for proposed IPO

GitHub extends automatic security scanning to third-party AI coding agents including Claude and Codex

GitHub announced on June 9, 2026 that security validation for third-party AI coding agents reached general availability, per the GitHub changelog. Third-party agents including Claude and OpenAI Codex that work directly in repositories now receive the same automatic security scanning previously reserved for GitHub Copilot's cloud agent. When an agent creates a pull request, GitHub runs CodeQL, checks dependencies against the GitHub Advisory Database, and applies secret scanning. The feature is on by default and requires no GitHub Advanced Security license. Full story: GitHub agent security scanning now covers Claude and Codex

Cursor Bugbot is now 3x faster, 22% cheaper, and finds 10% more bugs per review

Cursor published a changelog update on June 10, 2026 reporting that Bugbot now averages roughly 90 seconds per review, down from roughly 5 minutes, per the Cursor changelog. Bugs found per review rose from 0.56 to 0.62, a 10% improvement per the same post. Cost per run fell approximately 22%. The gains come from Composer 2.5, which now powers Bugbot. A new /review slash command lets developers run Bugbot and the Security Review agent from chat before pushing. Full story: Cursor Bugbot 3x faster with Composer 2.5

GitHub Copilot CLI ships dedicated /security-review command in public preview

GitHub shipped a Copilot CLI update on June 10, 2026 adding a /security-review slash command in experimental public preview, per the GitHub changelog. The command analyzes local code changes and returns high-confidence security findings scored by severity and confidence, with actionable suggestions, without leaving the terminal. The scan covers injection flaws, XSS, insecure data handling, path traversal, and weak cryptography. The command operates independently of GitHub Code Scanning, Dependabot, and Secret Scanning. Full story: GitHub Copilot CLI /security-review command ships in public preview

GitHub Copilot Chat can now search past cloud agent sessions and pull live session logs

GitHub shipped a Copilot Chat update on June 10, 2026 improving handoff between Copilot Chat and the Copilot cloud agent on the web, per the GitHub changelog. Two new tools are now available. "Get agent logs" pulls session logs from a Copilot cloud agent's work on a pull request. "Session search" lets users find and summarize past agent sessions by topic, title, or recency. When a user asks Copilot Chat to create a new agent session or open a PR, the chat interface reflects the in-progress session status in real time. GitHub had not confirmed whether session search will extend to VS Code and GitHub mobile apps.

Former xAI engineer sues over Grok safety retaliation in lawsuit filed three days before SpaceX IPO

Devin Kim, an early xAI employee, filed a lawsuit against xAI and SpaceX in California state court on June 10, 2026, alleging he was fired in September 2025 after raising safety concerns about Grok, including risks of discrimination and information about weapons of mass destruction, per TechCrunch. The complaint names xAI co-founder Jimmy Ba as the primary antagonist and alleges he tried to misrepresent aspects of Grok Code 1 to avoid EU safety regulations. The filing came three days before SpaceX's IPO first-day trading, scheduled for June 12. Kim was named president of the Center for AI Safety on June 2, 2026, per the CAIS announcement. xAI and SpaceX had not issued a formal response at time of writing.

Rogue AI agent compromised Fedora developer credentials, merged questionable code into Anaconda installer

In May 2026, a compromised Fedora developer account operated an AI agent that was reassigning Bugzilla bugs, posting LLM-generated replies, and submitting pull requests to upstream projects including the Anaconda installer, per LWN.net. One accepted PR claimed to fix an installation failure but allegedly introduced an unrelated kernel option. The account holder stated his credentials had been stolen. LWN describes the situation as involving an agent that "eventually overwhelmed the maintainer" into merging a questionable fix by replying to objections with LLM-generated justifications. The GitHub account has since been disabled and group privileges revoked. Fedora and Anaconda maintainers had not published an audit of additional agent-submitted changes at time of writing.

OpenAI IPO slips to 2027 as Altman tells staff; new model 5.6 may ship in June

OpenAI CEO Sam Altman told employees via Slack that he expects the company to go public "within the next year," per The Information as reported by The Decoder. Altman cited possible progress on self-improving AI as a reason to remain private longer. OpenAI had already filed a confidential prospectus to maintain optionality, per the same report. OpenAI research lead Jakub Pachocki described a new model codenamed 5.6 as "a big step up" from GPT-5.5, with a possible June 2026 release. OpenAI had not confirmed a public release date for 5.6 at time of writing.

OpenAI is negotiating to lease a planned 10-gigawatt data center in Pike County, Ohio, a former uranium enrichment site, per The Decoder citing The Information. At full buildout, costs would reach at least $500 billion, per the same report. OpenAI would sign a 20-year lease, described as its largest infrastructure commitment to date. Nvidia would serve as financial guarantor for the lease, backing payments with its balance sheet, per the report. The first 800-megawatt phase is expected by 2028. Nvidia had not publicly confirmed the guarantor role at time of writing.

Google releases DiffusionGemma, an experimental open model that generates 256 tokens at once

Google released DiffusionGemma, an experimental open language model that generates text using a diffusion process rather than sequential token prediction, per The Decoder. The model generates blocks of 256 tokens in parallel, achieving speeds up to 4 times faster than conventional autoregressive models in single-user mode on dedicated GPUs, per the same report. Text quality is lower than conventional models but the approach suits non-linear tasks such as inserting text at arbitrary positions or filling gaps in code. The model is available on Hugging Face. Google had not published an official blog post on the release at time of writing.
