Socket found a coordinated campaign of 17 malicious packages on npm and PyPI that impersonate the payment SDKs for Paysafe, Skrill, and Neteller to steal developer and cloud credentials. The fake libraries mimic real SDKs, returning success responses without contacting the real services, while quietly harvesting environment secrets such as Paysafe API keys, AWS keys, and GitHub and npm tokens and sending them to a server on AWS. Because these packages get pulled into build pipelines, a single one reaching a continuous integration runner can hand over the broad credentials those runners hold. The npm versions trigger when a payment key is present; the PyPI versions run on install regardless.
Researchers at Noma Labs showed that GitHub's new Agentic Workflows, which let an AI agent read issues and act on repositories automatically, can be tricked into leaking private code through nothing more than a public issue. The technique, GitLost, is indirect prompt injection: an attacker opens an ordinary-looking issue in an organization's public repository, buries plain-English instructions in it, and the agent, which often holds a token with read access across the org's repositories, follows them, fetches files from a private repo, and posts the contents in a public comment. No credentials, coding, or write access are needed. GitHub was notified, but researchers frame it as an architectural weakness.
Zimperium found RedWing, an Android bank-fraud operation rented out on Telegram as a finished product, complete with subscription tiers, guides, and a bot that builds each buyer a custom malicious app on demand, so no coding skill is needed. It spreads through phishing links leading to fake app-store pages that convincingly imitate Google Play and other stores. Once installed and granted permissions, it overlays fake login screens on real banking and crypto apps, reads incoming texts and screen content to capture one-time codes, and can silently forward the victim's calls to defeat phone-based verification. It also offers live screen control, keylogging, and camera access.
A phishing campaign is impersonating more than 30 well-known brands, including Adobe, Netflix, Coca-Cola, and OpenAI, in fake job-interview lures aimed at marketing professionals, with the goal of stealing their Google account credentials. Posing as recruiters from desirable companies, the attackers draw targets into a process that leads to a convincing Google sign-in page under their control. Because marketers often manage valuable brand, advertising, and analytics accounts tied to Google, a stolen login can open the door to ad fraud, data access, and further impersonation. The lure works by exploiting excitement about a career opportunity to lower the target's guard.
Researchers at the Hong Kong University of Science and Technology showed that the static scanners meant to vet add-on "skills" for AI coding agents like Claude Code can be fooled while the malware keeps working. Their technique, SkillCloak, either rewrites the tell-tale bytes a scanner looks for, using look-alike characters and line breaks, or hides the whole payload in a directory scanners skip, such as .git, behind a decoder that rebuilds it only when the agent runs the skill. Across eight scanners and 1,613 real malicious skills, the packing trick evaded detection more than 90 percent of the time. The researchers argue static scanning is not enough and released a runtime checker.
Zscaler found attackers using search-engine poisoning and hidden instructions on malicious websites to manipulate AI agents into making cryptocurrency payments. In one case, a hidden element on the page tells an AI agent that it must "resolve an error" by completing a payment, alongside code that starts a crypto transfer to a hardcoded wallet; the same page also shows human visitors ordinary payment options. Another campaign typosquats a decentralized-finance portfolio tracker and uses hidden prompts to convince agents the fake site is the real one. The attacker is seeding the scheme through several GitHub repositories, showing how autonomous agents that browse and act can be steered by content they read.
LevelBlue detailed QuimaRAT, a new Java-based remote access trojan sold as a service that runs across Windows, Linux, and macOS from the same codebase. Subscriptions range from about $150 for a month to $1,200 for lifetime access, lowering the bar for attackers to get cross-platform reach. Built around a modular design, it expands its capabilities through encrypted plugins that operators can load, update, or remove from their command server on the fly. It also uses several obfuscation techniques to keep changing how it looks to security tools without altering its behavior, so signatures based on its appearance are likely to go stale quickly.
Arctic Wolf detailed how affiliates of the Anubis ransomware group break in and stay hidden, drawing on intrusions across healthcare, finance, and manufacturing this year. Initial access came from stolen VPN credentials and from exploiting CitrixBleed 2, a NetScaler flaw that leaks session tokens from memory and lets attackers bypass multi-factor authentication. Once inside, the affiliates leaned on legitimate remote-management software such as ScreenConnect, Zoho Assist, and MeshAgent to blend in with normal IT activity, moving through networks with RDP and PsExec toward domain controllers, backups, and storage devices. They stole data using common cloud-transfer tools before encrypting anything, which is exactly where defenders have the best chance to catch them.
The FBI has issued an alert about TeamPCP, a criminal group that compromises the developer and security tools organizations trust inside their build pipelines to steal cloud credentials at scale. Rather than targeting end users, TeamPCP injects malicious code into legitimate software such as the Trivy and KICS scanners and the LiteLLM library, then pushes trojanized updates that continuous integration systems pull in automatically. Its malware harvests AWS, Google Cloud, and Azure tokens, Kubernetes service-account credentials, and more. One technique the FBI highlights is taking over npm maintainer accounts by re-registering the maintainer's long-expired recovery email domain, then using password reset to publish malicious package versions.
Socket detailed PolinRider, an active North Korean supply-chain campaign that has planted 108 malicious packages and a browser extension across the npm, Go, and Packagist ecosystems, expanding the developer-targeting activity behind this week's Rollup npm packages. Operators take over legitimate GitHub maintainer accounts, often via expired-domain or account-recovery abuse, then bulk-modify repositories and publish infected versions. To stay hidden, they rewrite Git history so malicious commits look old, pad one-line loaders with whitespace to push them off screen, and disguise payloads as font files. Some trigger automatically through VS Code task settings when a developer simply opens the project folder in an editor like VS Code or Cursor.
