Attackers compromised a legitimate maintainer's GitHub account for the Injective blockchain SDK and used it to push a malicious version of the widely used @injectivelabs/sdk-ts npm package, which has around 50,000 weekly downloads. The tainted code, disguised as usage telemetry, hooked the SDK's wallet key-generation functions to capture private keys and seed phrases, then sent them to a server made to look like legitimate Injective infrastructure. Trusted-publishing automation spread the malicious release across 18 packages within minutes, though it was live under an hour before being pulled. Because the theft can reach apps that used the SDK only indirectly, any wallet keys handled by affected versions should be treated as compromised.
Researchers have shown an attack, called HalluSquatting, that weaponizes the tendency of AI coding assistants to invent plausible-sounding names for software packages that do not exist. The attackers work out which fake names an AI reliably hallucinates, register those names first on a package registry or GitHub, and upload a trap that instructs the coding agent to install a reverse shell or runs code directly. When the assistant fetches the made-up dependency on a developer's machine, it runs the attacker's payload. Tested against nine AI coding assistants, the technique could let attackers pool compromised developer machines into a botnet for crypto mining, denial-of-service attacks, or ransomware.
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.
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.
Researchers at runZero disclosed seven vulnerabilities in FatFs, a tiny filesystem library that lets devices read FAT and exFAT media like USB drives and SD cards and that is bundled into the firmware of countless embedded and industrial products. The most serious, CVE-2026-6682, is an integer overflow when mounting a FAT32 volume that can lead to memory corruption and code execution, and several bugs are reachable through firmware update flows, not just physical media. The hard part is patching: FatFs is maintained by a single developer who did not respond to the researchers, so most of the memory-corruption flaws have no upstream fix and downstream vendors may never learn they are affected.
JFrog found a new set of malicious npm packages, linked to North Korea, that impersonate legitimate Rollup polyfill tooling closely enough to pass a quick dependency review, down to matching names and metadata. Installing them pulls in hidden second-stage packages disguised as SVG utilities, which fetch and run a JavaScript payload while checking that they are not in a sandbox or cloud build. The malware hunts for developer secrets, and notably targets the configuration and history of AI coding tools like Cursor alongside AWS, Azure, SSH, and npm credentials. Because build plugins run on developer machines and in CI, a single poisoned dependency can expose source code, tokens, and cloud keys.
Sekoia found a campaign that targets security researchers by planting a Python remote access trojan, ChocoPoC, in proof-of-concept exploits published on GitHub. Rather than putting malware in the exploit code itself, the attackers add a malicious package to the PoC's dependency list on the Python Package Index, so simply installing and running the exploit pulls down the trojan, which can run commands and steal data. At least seven repositories posed as PoCs for flaws in products like FortiWeb, PAN-OS, Ivanti Sentry, and Check Point VPN, with downloads spiking after each new vulnerability made headlines. One malicious package was fetched about 2,400 times, mostly on Linux.
A public proof-of-concept has been released for a critical flaw in libssh2 (CVE-2026-55200), the client-side SSH library embedded in curl, Git, PHP, backup agents, firmware updaters, and countless appliances. A malicious or compromised SSH server can send a crafted packet that corrupts memory on the connecting client, with no credentials or user interaction needed, potentially leading to code execution. Rated 9.2, the bug affects all versions through 1.11.1. The fix was merged into the source on June 12, but no tagged release exists yet, so distributions are backporting it. The hardest part is that libssh2 is often statically bundled, so package updates miss those copies entirely.
Researchers at Mozilla's 0DIN found that an AI coding agent told to clone and set up a seemingly harmless GitHub repository can be tricked into running malware that stays invisible to security scanners, the agent itself, and human reviewers. The trick is that nothing malicious sits in the repository's files. Instead, a routine-looking setup command runs a script that fetches a value hidden in a DNS TXT record and executes it as a shell command, pulling down and running an attacker's payload like a reverse shell. Because the payload lives outside the repo and arrives over DNS at setup time, code review and static scanning see nothing wrong.
