A Fake Coding Interview Is an Execution Request: Developer Safety Checklist

A coding interview repo is a request to run unknown code on a machine that holds your browser sessions, SSH keys, GitHub tokens, and cloud credentials. This checklist covers what to check before the call, what to look for in the repo, and what to do if you already ran it.

Hunting Lazarus Part IX: The Google Mirror

Five trojanized browser extensions extracted Google profile identity through chrome.identity and routed it through an Aptos blockchain dead drop. Before any wallet artifact moved, the extension asked Chrome who owned the browser.

Hunting Lazarus Part VIII: OtterCookie

OtterCookie is a separate JavaScript / Node.js RAT running beside BeaverTail in the Contagious Interview operation. Its Socket.IO control plane maintains a live roster of connected developer workstations and broadcasts it on a thirty-second clock. Part VIII breaks down the protocol, the collection profile, the uid/userKey batch labels, the npm and Vercel delivery layer, and the operational shift from stored-data theft to live surveillance of developer machines.

Research Note 2026-01: Unflagged Jenkins Infrastructure Used for Fake Exchange Deployment and FCCCall Malware Builds

Red Asgard identified an internet-exposed Jenkins server used as both a fake cryptocurrency-exchange deployment hub and a build environment for FCCCall trojanized video-conferencing installers. Eighteen FCCCall installers were produced from the same hub in a single five-and-a-half-hour window; thirteen named fake-exchange brands were deployed from the same environment. At preparation time, the infrastructure was not meaningfully represented in public malware-intelligence tooling. This note publishes sanitized indicators and detection guidance for defenders.

Hunting Lazarus Part VII: The Server That Was Not Just FTP

The Hetzner host at 195.201.104.53 was known as the BeaverTail FTP exfiltration sink. A scan of its non-standard ports found six Express.js services on the same machine, two of them OtterCookie command-and-control nodes – one live broadcasting macOS victim state, one silent predecessor still listening – plus a Linux deployment leaking a Windows development path on every request. One host. Multiple campaigns. Multiple malware families. Shared substrate.

Hunting Lazarus Part VI: The Factory That Ate Its Workers

Five operator workstations appeared in the campaign's own victim database. The same exfiltration pipeline that harvested developer credentials, wallet material, and source-repository tokens had ingested the staff who ran it — the supervisor, a persona operator, a test workstation, a provisioning workstation, and an operator infection that persisted sixty-eight days.

Why AI Security Fails at the Integration Layer

Most AI security discussion focuses on models, prompts, and jailbreaks. In practice, the most consequential failures happen where AI systems connect to operational infrastructure.

Hunting Lazarus Part IV: Real Blood on the Wire

It has been only days since we published Part III—where we asked whether we were hunting Lazarus or walking into a honeypot. We did not expect to be back this soon. But what we found makes everything before it look like a prologue.

Hunting Lazarus Part III: The Infrastructure That Was Too Perfect

We discovered a second malware family, mapped approximately 20 ghost servers with consistent configurations, attempted to exploit the C2 infrastructure—and ended up questioning whether we were hunting them, or they were hunting us.

Hunting Lazarus Part II: When the Dead Drop Moved to the Blockchain

The End of Syntax Privilege: Why LLMs Are Just the Latest Compiler

For most of software engineering history, the hardest skill was translating intent into correct syntax. Syntax mastery became a proxy for competence itself. Large language models quietly break that assumption - and force the industry to confront what engineering skill has always actually been.
