A recently patched security vulnerability in the 7-Zip archiver tool was exploited in the wild to deliver the SmokeLoader malware. The flaw, CVE-2025-0411 (CVSS score: 7.0), allows remote attackers to circumvent mark-of-the-web ( MotW ) protections and execute arbitrary code in the context of the current user. It was addressed by 7-Zip in November 2024 with version 24.09 . "The vulnerability was actively exploited by Russian cybercrime groups through spear-phishing campaigns, using homoglyph attacks to spoof document extensions and trick users and the Windows Operating System into executing malicious files," Trend Micro security researcher Peter Girnus said . It's suspected that CVE-2025-0411 was likely weaponized to target governmental and non-governmental organizations in Ukraine as part of a cyber espionage campaign set against the backdrop of the ongoing Russo-Ukrainian conflict. MotW is a security feature implemented by Microsoft in Windows to prevent the a...

Update: The NHS England Digital, in an updated advisory on November 20, 2025, said it has not observed in-the-wild exploitation of CVE-2025-11001, but noted that it's "aware of a public proof-of-concept exploit." It has since removed what it said were "erroneous references" to active exploitation. The original story follows below - A recently disclosed security flaw impacting 7-Zip has come under active exploitation in the wild, according to an advisory issued by the U.K. NHS England Digital on Tuesday. The vulnerability in question is CVE-2025-11001 (CVSS score: 7.0), which allows remote attackers to execute arbitrary code. It has been addressed in 7-Zip version 25.00 released in July 2025. "The specific flaw exists within the handling of symbolic links in ZIP files. Crafted data in a ZIP file can cause the process to traverse to unintended directories," Trend Micro's Zero Day Initiative (ZDI) said in an alert released last month. "An a...

The JavaScript (aka JScript) malware loader called GootLoader has been observed using a malformed ZIP archive that's designed to sidestep detection efforts by concatenating anywhere from 500 to 1,000 archives. "The actor creates a malformed archive as an anti-analysis technique," Expel security researcher Aaron Walton said in a report shared with The Hacker News. "That is, many unarchiving tools are not able to consistently extract it, but one critical unarchiving tool seems to work consistently and reliably: the default tool built into Windows systems." This leads to a scenario where the archive cannot be processed by tools like WinRAR or 7-Zip, and, therefore, prevents many automated workflows from analyzing the contents of the file. At the same time, it can be opened by the default Windows unarchiver, thereby ensuring that victims who fall victim to the social engineering scheme can extract and run the JavaScript malware. GootLoader is typically distrib...

The maintainers of the WinRAR file archiving utility have released an update to address an actively exploited zero-day vulnerability. Tracked as CVE-2025-8088 (CVSS score: 8.8), the issue has been described as a case of path traversal affecting the Windows version of the tool that could be exploited to obtain arbitrary code execution by crafting malicious archive files. "When extracting a file, previous versions of WinRAR, Windows versions of RAR, UnRAR, portable UnRAR source code and UnRAR.dll can be tricked into using a path, defined in a specially crafted archive, instead of a specified path," WinRAR said in an advisory. Anton Cherepanov, Peter Kosinar, and Peter Strycek from ESET have been credited for discovering and reporting the security defect, which has been addressed in WinRAR version 7.13 released on July 30, 2025. The development is the second time a WinRAR security vulnerability has been weaponized in the wild in as many years. In 2023, another vulnerabil...
