Most of this week’s threats didn’t rely on new tricks. They relied on familiar systems behaving exactly as designed, just in the wrong hands. Ordinary files, routine services, and trusted workflows were enough to open doors without forcing them. What stands out is how little friction attackers now need. Some activity focused on quiet reach and coverage, others on timing and reuse. The emphasis

Sysdig TRT analysis reveals VoidLink as a revolutionary Linux threat. Using Serverside Rootkit Compilation and Zig code, it targets AWS and Azure with adaptive stealth.

### Summary A memory leak vulnerability exists in the `LoadOpenCLDeviceBenchmark()` function in `MagickCore/opencl.c`. When parsing a malformed OpenCL device profile XML file that contains `<device` elements without proper `/>` closing tags, the function fails to release allocated memory for string members (`platform_name`, `vendor_name`, `name`, `version`), leading to memory leaks that could result in resource exhaustion. **Affected Version**: ImageMagick 7.1.2-12 and possibly earlier versions --- ### Details The vulnerability is located in `MagickCore/opencl.c`, function `LoadOpenCLDeviceBenchmark()` (lines 754-911). **Root Cause Analysis:** 1. When a `<device` tag is encountered, a `MagickCLDeviceBenchmark` structure is allocated (line 807-812) 2. String attributes (`platform`, `vendor`, `name`, `version`) are allocated via `ConstantString()` (lines 878, 885, 898, 900) 3. These strings are **only freed** when a `/>` closing tag is encountered (lines 840-849) 4. At function ex...

Security experts have disclosed details of a new campaign that has targeted U.S. government and policy entities using politically themed lures to deliver a backdoor known as LOTUSLITE. The targeted malware campaign leverages decoys related to the recent geopolitical developments between the U.S. and Venezuela to distribute a ZIP archive ("US now deciding what's next for Venezuela.zip")

### Summary There is a Zip Slip path traversal vulnerability in the jaraco.context package affecting setuptools as well, in `jaraco.context.tarball()` function. The vulnerability may allow attackers to extract files outside the intended extraction directory when malicious tar archives are processed. The strip_first_component filter splits the path on the first `/` and extracts the second component, while allowing `../` sequences. Paths like `dummy_dir/../../etc/passwd` become `../../etc/passwd`. Note that this suffers from a nested tarball attack as well with multi-level tar files such as `dummy_dir/inner.tar.gz`, where the inner.tar.gz includes a traversal `dummy_dir/../../config/.env` that also gets translated to `../../config/.env`. The code can be found: - https://github.com/jaraco/jaraco.context/blob/main/jaraco/context/__init__.py#L74-L91 - https://github.com/pypa/setuptools/blob/main/setuptools/_vendor/jaraco/context.py#L55-L76 (inherited) This report was also sent to setuptoo...

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

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.

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can

Cisco Talos’ Vulnerability Discovery & Research team recently disclosed vulnerabilities in Biosig Project Libbiosig, Grassroot DiCoM, and Smallstep step-ca. The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in adherence to Cisco’s third-party vulnerability disclosure policy, except for Grassroot, as the

This week’s cyber stories show how fast the online world can turn risky. Hackers are sneaking malware into movie downloads, browser add-ons, and even software updates people trust. Tech giants and governments are racing to plug new holes while arguing over privacy and control. And researchers keep uncovering just how much of our digital life is still wide open.
