Summary from the TLDR InfoSec newsletter

Microsoft discovered Trojanized Next.js repositories linked to North Korea's Lazarus APT that deliver backdoors through fake job-recruitment coding challenges, achieving RCE and persistent C2 access on developer machines. The repositories exploit VS Code workspace automation via malicious .vscode/tasks.json files or embed obfuscated loaders in build assets that fetch attacker-controlled JavaScript at runtime. Security teams should enforce strict IDE trust policies, monitor for anomalous Node.js outbound connections, and treat developer workflows as a privileged attack surface.
