Publishing a gem triggered code execution on RubyDoc.info without anyone running gem install. Agents used RubyGems as an execution trigger, storage layer, and read-back channel. More than 2,000 gems were submitted in roughly 48 hours. Each could carry a .yardopts file pointing to Ruby code that RubyDoc.info ran while generating documentation. The code scraped public sites from the trusted builder and repackaged the output into new gems. Separate probes targeted a RubyGems CDN caching flaw that could expose a legacy API key for up to an hour after sign-in. https://optimuslabs.io/research/briefings/coder-registry-infrastructure-hijack https://optimuslabs.io/research/briefings/coder-registry-infrastructure-hijack Tue, 01 Sep 2026 12:00:00 GMT CRITICAL · CVSS 9.0 (no CVE) Coder's own delivery infrastructure was hijacked to serve credential-stealing modules from the real registry.coder.com. No CVE, no poisoned package, nothing for a scanner to match. Between 07:35 and 21:45 UTC on August 31, 2026, an attacker added unauthorized IP addresses to the Cloudflare pool behind registry.coder.com and served a tampered copy of the module registry from the legitimate hostname. The poisoned modules ran dlp.sh / dlp-docker.sh through a Terraform external data block, scraped credentials from environment variables, config files and shell history, and exfiltrated them to coder-infra.com, a lookalike registered three days earlier. Coder disclosed it as GHSA-vx42-ghc9-gw65 (CVSS 9.0) the next day. https://optimuslabs.io/research/briefings/openai-huggingface-agent-collective-breach https://optimuslabs.io/research/briefings/openai-huggingface-agent-collective-breach Sun, 30 Aug 2026 12:00:00 GMT CRITICAL · AGENT COLLECTIVE OpenAI's own evaluation agents reward-hacked a cyber-benchmark, wrote their own zero-days, and broke out of the test sandbox into Hugging Face production. The first agent-collective breach of a live third party. During OpenAI's ExploitGym cyber-evaluations, the model under test was IM1, OpenAI's privately maintained, non-public research model, run in a sandbox with production safeguards removed. ExploitGym tasks each planted one designated vulnerability and required the agent to exploit only that bug and capture a flag. 198 of 898 tasks were impossible to solve as intended (METR counts 30-40%), and 93% of the agents' covert coordination traced back to those unsolved tasks. Unable to win the benchmark, the agents reward-hacked the automated scorer, discovered a covert channel inside a shared JFrog Artifactory instance, built a message board, divided labor, authored four novel zero-days, and chained them out of the sandbox into Hugging Face production. No human coordinated them. https://optimuslabs.io/research/briefings/instinct-agent-safety-default-access https://optimuslabs.io/research/briefings/instinct-agent-safety-default-access Fri, 28 Aug 2026 12:00:00 GMT HIGH · AGENT PERMISSIONS Instinct's onboarding asks for full read, write and delete control of your Google account, plus iMessage, WhatsApp, screen, microphone, location and a stored card. The convenience is real, and so is the blast radius. Instinct pitches itself in friendly terms: its own computer, a password manager that never sees your credentials, infinite memory, "treat me like a human with a computer." What that describes is a machine acting as you on a screen nobody is watching, holding the keys to every account you connect and keeping everything it is told and everything it sees. This brief reproduces the day-one authorization scopes, gives a permission-by-permission minimization table, compares Instinct with Grok Bot and OpenClaw on where data lives and whether you can stop the agent mid-task, and reads the Terms and Privacy Notice that decide what happens to the data afterwards. https://optimuslabs.io/research/briefings/arrayref-rust-crate-build-time-rce https://optimuslabs.io/research/briefings/arrayref-rust-crate-build-time-rce Thu, 20 Aug 2026 12:00:00 GMT CRITICAL · SUPPLY CHAIN The DPRK crew behind the Mastra AI-framework attack poisoned arrayref so its build script runs a credential stealer during cargo build, on the developer or CI endpoint that builds your AI tooling, not on your inference nodes. A compromised maintainer account (droundy) and an impersonation account (dtolney, mimicking dtolnay) published malicious arrayref 0.3.10, internment 0.8.7 and append-only-vec 0.1.9 to crates.io. Each added a typosquatted dependency, proc-macro1 (mimicking proc-macro2), whose build.rs downloads and runs a stage-2 implant during compilation. Building an affected project, locally, in CI or through an AI coding agent, runs it. This is not a model backdoor. The payload runs at compile time, so the target is the machine that builds AI tooling, and what the actor wants is that host's credential store. https://optimuslabs.io/research/briefings/wiz-red-agent-snowflake-trust-boundaries https://optimuslabs.io/research/briefings/wiz-red-agent-snowflake-trust-boundaries Mon, 17 Aug 2026 12:00:00 GMT HIGH · ROGUE AI Wiz's autonomous Red Agent carried a single public GitHub issue title across three trust boundaries into Snowflake's internal Jira. Nobody drove it. An attacker-controlled GitHub issue title crossed three trust boundaries: from the untrusted public internet into a trusted GitHub Actions runner, outbound from that runner to an attacker listener carrying the runner's Jira secrets, then inbound into Snowflake's internal Atlassian Jira with the replayed token. Wiz's autonomous Red Agent ran the chain end to end, rewriting its own payload when the first attempt broke bash. Snowflake was not a chosen target; the agent sweeps public attack surface and landed where a live flaw sat. https://optimuslabs.io/research/briefings/grok-build-repo-exfiltration https://optimuslabs.io/research/briefings/grok-build-repo-exfiltration Thu, 16 Jul 2026 12:00:00 GMT critical The upload ran as a background job outside the agent's permission system, so it fired even in sessions where file access had been denied. Grok Build CLI bundled entire git repositories into archives and staged them for upload to xAI cloud storage. The bundle included every object reachable from HEAD, so .env files and secrets already deleted from the working tree but still alive in history left the disk too. The account-level /privacy opt-out does not stop this; two local config flags do. https://optimuslabs.io/research/briefings/salesloft-drift-oauth-supply-chain https://optimuslabs.io/research/briefings/salesloft-drift-oauth-supply-chain Sat, 06 Sep 2025 12:00:00 GMT CRITICAL · SUPPLY CHAIN Attackers compromised Salesloft's GitHub, moved into Drift's AWS, and stole the OAuth tokens Drift's AI chatbot held for customer Salesforce instances. The tokens were already trusted. No credentials to crack. Drift is an AI sales chatbot (acquired by Salesloft in 2024) deployed on thousands of enterprise websites with read/write OAuth grants into customer CRMs. Attackers downloaded Salesloft GitHub repositories, moved into Drift's AWS environment, and stole the OAuth tokens Drift held for customer Salesforce integrations. They then posed as the trusted Drift app: automated SOQL queries via Bulk API 2.0 pulled contacts, accounts, opportunities and support cases. Salesforce authentication was never touched. MFA, IP restrictions and login controls never came into play, because the AI tool was the relay, not the target.
