Hacktron researchers disclosed a one-click universal XSS (UXSS) in Perplexity Comet, a Chromium-based AI browser with the Comet Assistant agent extension. The extension's manifest trusts the wildcard https://.perplexity.ai/ in externallyconnectable, so a single XSS on any perplexity.ai subdomain can reach privileged extension message hand…
Researchers at Hacktron (author ginoah) described five bypasses of the Vercel WAF rules protecting against React2Shell (CVE-2025-55182), a pre-auth RCE in React Server Functions affecting Next.js 15.x–16.0.6 and other React-based frameworks. The bypasses were found during a Vercel bounty challenge. Per Vercel's writeup, 116 researchers to…
Citizen Lab reports that Candiru spyware was delivered to devices at Al Jazeera Media Network through targeted online advertisements, in a zero-click attack that only required the malicious ad to render on the victim's device. Citizen Lab calls the technique AdFection and says its report is the first public technical confirmation of merce…
Researchers at Hacktron disclosed a vulnerability chain in OpenAI's ChatGPT Atlas Chromium-based AI browser that lets an attacker monitor all open tabs and capture OAuth authorization codes for any site, effectively breaking the same-origin policy. Atlas exposes Mojo IPC bindings to all .chatgpt.com and .openai.com origins, so a single XS…
FortiGuard Incident Response reports a supply chain attack on the QuickFox Windows application, whose trojanized components deployed the FDMTP implant to users. QuickFox's user base is mainly Chinese international students and expats. Affected Windows versions are those later than v3.0.35 and earlier than v3.55.6. QuickFox has removed the…
Researcher Pedro Cruz (gankd) documents two Client-Side Path Traversal (CSPT) chains found in production bug bounty programs. The first turns CSPT into Stored XSS and account takeover on a payments platform's Angular POS single-page application. The second, found with Felipe Torres, triggers unauthorized account deletion on one of the lar…
On August 12, 2026, an npm user (rootdaddy-msrc, author field r00tdaddy) published 21 packages that squatted the unscoped CLI binary names declared in the bin field of Google-affiliated scoped packages, such as ngsw-config (from @angular/service-worker) and bazelisk (from @bazel/bazelisk). Scoped publishing, registry allowlists and lockfi…
Two beta versions in the @joyfill npm scope, published on July 28, 2026, carried the same blockchain C2 loader seen in the earlier astro.config.mjs attack, which the article ties to the PolinRider campaign. The attacker published through the legitimate scope (a form-builder SDK with three maintainers) under the beta dist-tag. The maliciou…
On August 28, 2026, an attacker published 10 malicious versions of the npm package @7nohe/openapi-react-query-codegen (about 671K downloads/month) without stealing any credentials. They abused the repository's GitHub Actions release.yml workflow, which had an issuecomment trigger with no author-association gate. Commenting npm publish on …
FortiGuard Labs describes a large-scale, global campaign that uses heavily obfuscated JScript droppers to launch an AutoIt/Lua-based loader with low detection rates. The loader delivers several popular RATs and infostealers, including a version of Snake Keylogger. The infection chain relies on business email compromise tactics, impersonat…
An attacker pushed forged commits to the default branches of two unrelated GitHub projects, hugo-paper and mevn-cli. The commits add a preinstall hook (scripts/preinstall.js) that downloads and silently runs a second-stage script from buildwithknexus.xyz during npm install or bun install. The commits copy the author, date and message of t…
F5 Labs, using Efflux sensor telemetry, analyzed December 2025 exploitation of React2Shell (CVE-2025-55182), a CVSS 10.0 unsafe deserialization RCE in React Server Components. It was disclosed on 3 December 2025 and rose to second place among the most exploited CVEs, behind only CVE-2017-9841. Within days of disclosure, actors moved from …
SafeDep found a remote access implant in mathmain, an npm package that copies mathjs, and in two sibling packages, mathsbase and math-universe. The malicious code ships AES-256-GCM encrypted and activates only when lusolve() is called with matrix data whose LU lower factor serializes to a specific password. Once decrypted, the implant tak…
Palo Alto Networks Unit 42 reports that a suspected advanced actor tracked as CL-STA-0954 (aka UNC5820) deployed a previously unreported memory-resident ARM64 implant, PEERSTITCH, on Fortinet FortiGate firewalls. The group exploited the FortiOS path traversal flaw CVE-2025-61624 for the final stage. The intrusion hit a telecommunications …
On 4 August 2026, an npm worm published 2,234 poisoned versions across 444 package names, using credentials from twelve organisations. Affected scopes include @ornikar, @deliveroo, @onereach, @or-sdk, @servicetitan, @qlik, @picsart, and the keyv and cacheable families. The keyv, flat-cache, file-entry-cache and cacheable-request packages …
SafeDep flagged the malicious npm package ulid-xyz in June 2026. It typosquats ulidx and is a cross-platform remote access trojan. It is delivered through a three-layer transitive dependency chain: ioredis-xyz (a clone of the legitimate ioredis client) depends on redis-type-xyz (an empty manifest posing as Redis OM), which in version 1.10…
SafeDep reports that the PolinRider loader family now resolves its C2 servers from Ethereum mainnet. The loader reads small transactions from operator wallets and decodes the recipient address as an IP:port. SafeDep confirmed 35 GitHub repositories carrying the loader at HEAD on 2026-09-30 (7,578 stars and 2,884 forks combined). The inves…
SafeDep identified a malicious tensorlake npm release, version 0.5.144 (about 106,000 monthly downloads), that ran a Mini Shai-Hulud worm on install. It was published at 01:12:07 UTC on 8 October and flagged by SafeDep eight minutes later. The attacker used a repository administrator account to commit the payload to main through the GitHu…
A joint advisory (AA26-281A) attributes China-based malicious cyber activity to Integrity Technology Group (Integrity Tech), a for-profit company with links to the Chinese government. The company builds and sells tools, hosts infrastructure and compromises networks worldwide. The actors' TTPs are consistent with Flax Typhoon, Ethereal Pan…
Researchers at SafeDep identified imgdecode, a malicious npm package tied to the long-running MALFEX supply chain campaign first documented by Checkmarx and CloudSEK. Published on September 30, 2026 by user "malfexteste8", it has been downloaded 979 times and was still available at the time of reporting (latest version 1.0.3). MALFEX has …
