A China-nexus threat actor known as UAT-7290 has been attributed to espionage-focused intrusions against entities in South Asia and Southeastern Europe. The activity cluster, which has been active since at least 2022, primarily focuses on extensive technical reconnaissance of target organizations before initiating attacks, ultimately leading to the deployment of malware families such as RushDrop

The internet never stays quiet. Every week, new hacks, scams, and security problems show up somewhere. This week’s stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Honeypot Traps Hackers Hackers Fall for

Talos assesses with high confidence that UAT-7290 is a sophisticated threat actor falling under the China-nexus of advanced persistent threat actors (APTs). UAT-7290 primarily targets telecommunications providers in South Asia.

We unpack a trojanized WinRAR download that was hiding the Winzipper malware behind a real installer.

# pnpm v10+ Git Dependency Script Execution Bypass ### Summary A security bypass vulnerability in pnpm v10+ allows git-hosted dependencies to execute arbitrary code during `pnpm install`, circumventing the v10 security feature "Dependency lifecycle scripts execution disabled by default". While pnpm v10 blocks `postinstall` scripts via the `onlyBuiltDependencies` mechanism, git dependencies can still execute `prepare`, `prepublish`, and `prepack` scripts during the fetch phase, enabling remote code execution without user consent or approval. ### Details pnpm v10 introduced a security feature to disable dependency lifecycle scripts by default ([PR #8897](https://github.com/pnpm/pnpm/pull/8897)). This is implemented by setting `onlyBuiltDependencies = []` when no build policy is configured: **File:** `pkg-manager/core/src/install/extendInstallOptions.ts` (lines 290-291) ```typescript if (opts.neverBuiltDependencies == null && opts.onlyBuiltDependencies == null && opts.onlyBuiltDepend...

A cybercrime gang known as Black Cat has been attributed to a search engine optimization (SEO) poisoning campaign that employs fraudulent sites advertising popular software to trick users into downloading a backdoor capable of stealing sensitive data. According to a report published by the National Computer Network Emergency Response Technical Team/Coordination Center of China (CNCERT/CC) and

Synthient discovers over 2 million Android TV boxes and smart TVs hijacked by the Kimwolf botnet. Learn how hackers are using home devices to launch DDoS attacks and how you can protect your home network.

The year opened without a reset. The same pressure carried over, and in some places it tightened. Systems people assume are boring or stable are showing up in the wrong places. Attacks moved quietly, reused familiar paths, and kept working longer than anyone wants to admit. This week’s stories share one pattern. Nothing flashy. No single moment. Just steady abuse of trust — updates, extensions,

## Security Advisory: Stored XSS Leading to Admin Account Takeover **Affected Versions:** ≤ 5.1.0 **Vulnerability Type:** CWE-79: Stored Cross-Site Scripting --- ## Summary A lower-privileged user with campaign management permissions can inject malicious JavaScript into campaigns or templates. When a higher-privileged user (Super Admin) views or previews this content, the XSS executes in their browser context, allowing the attacker to perform privileged actions such as creating backdoor admin accounts. The attack can be weaponized via the **public archive feature**, where victims simply need to visit a link - no preview click required. --- ## Required Attacker Permissions ``` campaigns:manage - Create/edit campaigns campaigns:get - View campaigns lists:get_all - Access lists templates:get - Access templates ``` **Note:** These are common permissions for content managers who are not full admins. --- ## Attack Vectors ### Vector 1: Raw HTML (Direct ...

The SignalK appstore interface allows administrators to install npm packages through a REST API endpoint. While the endpoint validates that the package name exists in the npm registry as a known plugin or webapp, the version parameter accepts arbitrary npm version specifiers including URLs. npm supports installing packages from git repositories, GitHub shorthand syntax, and HTTP/HTTPS URLs pointing to tarballs. When npm installs a package, it can automatically execute any `postinstall` script defined in `package.json`, enabling arbitrary code execution. The vulnerability exists because npm's version specifier syntax is extremely flexible, and the SignalK code passes the version parameter directly to npm without sanitization. An attacker with admin access can install a package from an attacker-controlled source containing a malicious `postinstall` script. ### Affected Code **File**: `src/interfaces/appstore.js` (lines 46-76) ```javascript app.post( [ `${SERVERROUTESPREFIX}/app...
