Do the math: How we took over ChatGPT accounts

Parameter Labs describes a chain that turned a public ChatGPT share link into JavaScript running as chatgpt.com in the victim's session. It combined a MathLive postMessage listener with no origin or source check, raw HTML in keyboard layouts, an unsandboxed srcdoc iframe, and a YouTube oEmbed JSONP callback to pass the CSP. The code read private conversations through backend APIs. OpenAI fixed it on 26 October 2026 and rated it P1.

4 real? Tracking exploitation and patching of eMudhra’s weak keys

Cloudflare's follow-up on eMudhra's eight trivially recoverable intermediate CA keys (such as 4, 56 and 66), disclosed 19 October 2026. Pingora logging showed about 22,000 handshakes with the weak keys, including about 160 forged certificates made within hours of disclosure. Probes on 50 million challenge pages show many bots, old browsers and Android WebView still trust the chain.

Rekt - SingularityNET - Rekt

SingularityNET exploit (19 September 2026): attackers with signing authority exposed through a cloud infrastructure breach drained 8.72M FET from the Ethereum bridge converter, then minted about 2.3 billion AGIX, NTX, WMTX and CGV. Rekt's transaction-level reconstruction puts gross liquid proceeds near $2.29M, not the $16.77M headline, and traces laundering via Chainflip, Baltex and THORChain.

Claude Code regularly sends each background agent’s transcript to its model

no-agent-summary.js is a roughly 70-line Bun preload by Flamerix AI that stops Claude Code from re-sending each background agent's full transcript to its model every ~30 seconds for a status-line summary. The write-up cites OpenTelemetry measurements of 18 to 26 percent of spend (since version 2.1.232), explains the setTimeout hook, and gives install and verify steps. It was tested on Linux with Claude Code 2.1.257 to 2.1.312.

GitLab Security Incident: Attempted Exploitation of CVE-2026-97229

Alpine Linux incident report on attempted exploitation of CVE-2026-97229 (CVSS 10.0), a regex-evaluation bug in Ruby's Onigmo engine reachable through GitLab CI configuration. An attacker crashed workers 8 times on 20 and 21 October 2026. Upgrading to GitLab 19.3.6 did not fix it because the patch sits in GitLab's bundled Ruby. Alpine rebuilt the instance and found no tampering with aports or releases.

Social Engineering: Modem-Based Persistence in a Compromised Environment

The article describes reflashing a Huawei E3372h-153 HiLink 4G USB modem so its embedded Linux OS runs an OpenVPN client over the mobile network, creating a covert, network-independent persistence channel after physical USB access. It walks through enabling debug mode, flashing firmware, disabling CD-ROM emulation, configuring DHCP and autorun scripts, and chaining a second L2VPN tunnel to bridge the attacker directly onto the victim's Ethernet segment for tools like Responder. Defense guidance focuses on restricting USB ports and disabling USB network adapters via policy.

AI, Scripts, Operator: Inside the ConnectWise Attack

Huntress analyzes Entra sign-in and audit logs from the ConnectWise Cloud Backup credential abuse of 15 October 2026 to judge whether a script, a person or an LLM agent drove it. It found a thread-pool spray, trial-and-error credential planting with a retry added within 55 seconds, and pilot-then-batch targeting. Huntress rates LLM involvement low to medium on its own data and medium to high with Microsoft's Storm-0940/ARTEX attribution. It ends with detections for service principal role self-assignment and vendor app baselining.

Gheist: Attempted Scaled Abuse of Stolen GitHub Tokens Stumbles

Gheist is a campaign tracked by Wiz Research since 15 September 2026 that uses stolen GitHub tokens to push a sync-check workflow on ci-sync-* branches in every reachable repository. The workflow prints base32-encoded secrets into logs, which the tool downloads through the GitHub API and then deletes. Over 13,500 branches from 850+ accounts were recovered. The post covers the two tool variants, a buggy self-hosted runner payload, GitHub's approval hold (which does not cover private repositories), overlaps with other campaigns, hunting queries, IOCs and hardening steps.

Abusing Linux fanotify for Anti-Forensics

Abusing Linux fanotify for anti-forensics: a privileged userspace process can use the fanotify API to deny other processes the right to open an otherwise normal file. Reads fail with EPERM even for root, while name, ownership, timestamps and permissions look ordinary, so a scanner that cannot open a file may report no detections without inspecting it. Defenders can find malicious fanotify groups and marks via /proc/<pid>/fdinfo, or acquire at the filesystem level instead of opening the pathname.

From JavaScript to Renderer Code Execution: Three V8 Vulnerabilities and Two v8CTF Flags | depthfirst

Depth First Security's write-up describes three V8 bugs found using its dfs-large1 research tooling: CVE-2026-78938, a type confusion in Promise.prototype.finally that lets an internal helper be constructed and return a primitive; CVE-2026-79236, a TurboFan load-elimination bug that keeps a stale property-array pointer after object migration; and a shared WebAssembly memory sandbox escape (issue 546253900) caused by mismatched backing-store registration during serialization. It walks through turning each memory bug into addrof/fakeobj primitives, chaining either with the sandbox escape to reclaim a freed V8 isolate via a WebSocket allocation, and pivoting through a CFI-constrained ROP chain to achieve Chrome renderer code execution, earning two v8CTF flags. Fixes landed between August 20 and 25, 2026.

Review of the "Misalignment in high-stakes settings" section in Anthropic's Risk Report (August 2026)

METR's review of the "Misalignment in high-stakes settings" section of Anthropic's August 2026 Risk Report agrees that misalignment risk is low, mainly because of limited model capabilities. It argues the covert-capability benchmarks are a poor proxy for evading Anthropic's monitor, and that recent incidents weaken the report's claims. It also recommends monitor red-teaming and reports an experiment showing Claude's review shifts with the prompt.
