Overview Two vulnerabilities have been identified in FastStone Image Viewer 8.3 that may allow remote code execution or control-flow corruption when processing specially crafted image files. The affected components include the JPEG 2000 (JP2) parser and the PSD file parser. An attacker can exploit these vulnerabilities by causing the application to automatically or interactively process malicious image files. Description FastStone Image Viewer is a software tool for browsing, editing, and managing images, offering features like full‑screen viewing, batch processing, red‑eye removal, and a wide range of editing effects. It supports virtually all major image and RAW formats and includes conveniences like slideshows, comparison tools, scanner support, and screen capture. CVE-2026-30040 A critical heap-based buffer overflow vulnerability exists in FastStone Image Viewer, versions 8.3 and earlier. The issue is triggered during the parsing of JPEG 2000 (JP2) files due to a malformed QCD (quantization default, 0xFF5C ) marker in the FSViewer.exe process. By exploiting this flaw, a remote attacker can overwrite the EIP (instruction pointer) and execute arbitrary code in the context of the current process via a crafted JP2 file. Notably, this issue does not require the victim to directly open the crafted JP2 file. When the application enumerates directories during automatic thumbnail generation, files within two directory levels are parsed by the JP2 decoder. If the malicious JP2 file is present within this enumeration range (for example in the user’s Downloads folder), the vulnerability is triggered automatically. CVE-2026-30041 An integer overflow vulnerability exists in the PSD parser of FastStone Image Viewe

What happens when you clear dozens of Trail of Bits engineers’ schedules, pair them with every open-source maintainer they can contact, and unleash the latest frontier models like GPT-5.5-Cyber on critical open-source targets? Thanks to our partnership with OpenAI and its Daybreak initiative, we can report that the impact is hundreds of discovered bugs, 64 pull requests, and 51 issues filed across 19 projects (with many more still undergoing coordinated disclosure). That was just the first week of Patch the Planet . Frontier models like GPT-5.5-Cyber are producing a firehose of security findings, and already-stretched maintainers must sift through all of it to separate real vulnerabilities from plausible-sounding false positives. Patch the Planet is different: with our experts orchestrating and triaging findings, we handle the work of fixing and hardening the code alongside the people who maintain it. The first week of Patch the Planet covered 19 projects across cryptography, networking, language infrastructure, and software supply chain. Among these 19 projects were cURL, NATS, pyca, Sigstore, aiohttp, the Go project, freenginx, Python and python.org, urllib3, PyPI, SimpleX, Valkey, and RustCrypto. Over 30 projects have joined the initiative so far, and we’re rapidly expanding it to include more; if you maintain an open-source project, apply to join !

CVE

Overview Microsoft Windows Recovery Environment (WinRE) provides a mechanism for recovering and repairing Windows systems using an alternate boot environment. Under certain platform implementations, access to WinRE may allow an attacker to bypass firmware security controls, including administrator-configured UEFI/BIOS passwords. An attacker with physical or administrative access to a device may be able to leverage WinRE-related boot mechanisms to circumvent firmware protections and gain unauthorized access to system resources. Description Microsoft Windows versions 10 and 11 include the WinRE capability, a recovery platform that supports features such as the F11 recovery menu and the Reset this PC functionalities. WinRE is commonly used for system recovery, troubleshooting, and remote support scenarios. When WinRE is invoked, the system reboots into a recovery environment that may use an alternate boot path from the standard operating system startup sequence. Depending on the platform and firmware implementation, the alternate boot path may not consistently enforce the same UEFI/BIOS security controls that are applied during a normal boot process. A security concern has been identified in certain WinRE implementations where administrative UEFI/BIOS passwords may not be enforced during specific recovery operations. This inconsistency in the boot execution path may allow an attacker with physical access to a device to bypass firmware-level protections. Such scenarios are commonly associated with "Evil Maid" attacks, in which an attacker gains temporary physical access to an unattended system and modifies its boot configuration or security settings. In UEFI-based systems, the UEFI boot manager sup

It looks like a mic clarity app but bundles a hidden second executable that runs in the background. Here's what it actually does: logs your keystrokes, captures your screen, hijacks your clipboard, records microphone audio, and sends everything out to a remote server encrypted. It also deletes Windows Shadow Copies which is standard ransomware behaviour to stop you recovering your files. It actively checks if it's running in a sandbox too, which is why I'm glad I tested it before running it on a real machine.

In the previous post we walked through WasmForge, our Go-to-WebAssembly loader that takes existing signatured Go tools and ships them as opsec-safe binaries. This approach doesn’t just apply to Go, however, as there are many languages that can compile to WebAssembly. Another language of interest to us, especially regarding legacy tools which have been over-signatured, is C#. In short, we got several GhostPack tools working through WasmForge. Rubeus and Seatbelt both run as PE binaries that pass through the same outer host which we use for Sliver, with most of their commands functioning at full parity to the original C# code. The mechanism is .NET’s NativeAOT-WASI toolchain plus a non-trivial amount of bridge code that we wrote with heavy LLM assistance.

CERT/CC Jun 18

Overview Multiple vendor-signed UEFI applications are vulnerable to Secure Boot bypass via a "Bring Your Own Vulnerable Driver" (BYOVD)-style attack. If a target system trusts the affected vendor’s certificate, an attacker can exploit these applications to execute arbitrary code during the early pre-boot phase before the operating system initializes. To mitigate this risk, system administrators should apply updates to the UEFI Forbidden Signature Database (DBX) that revoke trust in the affected vendor-signed binaries, preventing these vulnerable applications from executing during the boot process. Description The Unified Extensible Firmware Interface ( UEFI ) standard defines the modern firmware architecture used to initialize hardware and transfer control to the operating system during system startup. On systems with Secure Boot enabled, UEFI applications and drivers must be cryptographically signed and verified before execution. Trust for these signatures is established through several firmware-managed databases, including the authorized signature database (DB), which commonly contains certificates from original equipment manufacturer (OEM) vendors, operating system authorities, and other supply-chain partners in the UEFI ecosystem. The UEFI shell is a command-line application that allows advanced users to interact directly with the UEFI environment to run diagnostics or special tasks prior to the operating system boot. Other UEFI applications, such as bootloaders, manage the operating system startup sequence or load specific drivers before the main OS initializes. Some of these applications possess functionalities that can manipulate system memory, modify sensitive NVRAM variables, or load raw drivers. If a vendor-signed application inadvertently exposes the

For the past four years, a sprawling Android-based botnet called Popa has forced millions of consumer TV boxes to relay Internet traffic linked to advertising fraud, account takeovers, and mass data-scraping efforts.

Malicious streaming devices sold online that enroll the user’s home Internet address in a residential proxy service. Image: HUMAN Security. Popa is a massive botnet, but by all accounts it is unlike traditional botnets that enlist compromised systems in destructive activities, such as coordinating huge distributed denial-of-service attacks.

I've been reversing the 2M+ user Volume Booster Chrome extension and found something interesting. Between v1.0.3 (2025-06-27) and v1.0.4 (2025-07-02), the extension added: "content_scripts": [{ "matches": ["<all_urls>"], "js": [ "vendor/GiveFreely-content.umd.js", "content-script.js" ] }] The previous version was essentially a small audio booster. The newer version introduces a Give Freely / Wildlink component that appears to support merchant detection, affiliate attribution, and donation campaigns. No new permissions were added, meaning existing users would have received the update automatically without a new Chrome permission approval prompt. I've also found the same Give Freely / Wildlink infrastructure in multiple unrelated extensions, which makes me think it's being distributed as a white-label monetization/fundraising SDK. I'm still investigating and considering whether this is worth adding to MalExt. At this point I don't have evidence of malware, credential theft, or anything overtly malicious just a significant expansion of functionality in a 2M-user extension. Curious what others think. Is this a transparency/privacy concern, or just a normal extension monetization model? Any opinions or prior research on Give Freely / Wildlink would be appreciated so i can added to [malext.io](http://malext.io)

Overview Earlier this year, a team at Praetorian was building Constantine , our automated 0-day discovery engine. I wanted to find techniques worth folding into it, so on the side I started poking at the FreeBSD kernel with Claude Code, running on Opus 4.6, which was the latest Opus model at the time. A few days of work turned up real bugs and a weekend after that produced two working exploits capable of escaping from a FreeBSD jail. This article is part of a two-part series. In part one, I will be focusing on the methodology used to uncover the identified vulnerabilities and part two will focus on the methodology we leveraged to develop and exploit the vulnerabilities. It’s been several months since I disclosed roughly eight separate vulnerabilities to the FreeBSD security team. The reality is that this is a volunteer team and they are likely overwhelmed by the sheer number of vulnerabilities being identified within FreeBSD by various security researchers leveraging large language models.

TL;DR: Sulla is an open source SMB secret scanner for discovering credentials exposed in SMB shares across enterprise networks. It leverages our recently released Titus Go library, resulting in an easy-to-use, adaptable, and highly performant standalone binary. Every network penetration tester knows the struggle: reviewing network shares for sensitive material is a painful must-do. With anything more than a handful of shares, manual review quickly becomes tedious if not outright infeasible. But automated secret scanning solutions produce nearly unworkable quantities of output, with actual secrets few and far between, not to mention requiring a Windows attack box. Sulla solves this issue by combining Praetorian’s years of secrets detection innovation with a clean, user-friendly interface purpose-built for internal networks. The result is a focused SMB secret scanner that pentesters can run from any Linux box and trust to surface high-signal findings. Sulla is also integrated end-to-end in the Guard, Praetorian’s all-in-one Continuous Threat Exposure Management platform, ensuring SMB secrets are identified as they appear in your environment.
