A new security weakness has been disclosed in the WinRAR trialware file archiver utility for Windows that could be abused by a remote attacker to execute arbitrary code on targeted systems, underscoring how vulnerabilities in such software could beсome a gateway for a roster of attacks. Tracked as CVE-2021-35052, the bug impacts the trial version of the software running version 5.70. "This vulnerability allows an attacker to intercept and modify requests sent to the user of the application," Positive Technologies' Igor Sak-Sakovskiy  said  in a technical write-up. "This can be used to achieve remote code execution (RCE) on a victim's computer." The issue has since been addressed in WinRAR version 6.02 released on June 14, 2021. Sak-Sakovskiy noted that an investigation into WinRAR began after observing a JavaScript error rendered by MSHTML (aka Trident), a proprietary browser engine for the now-discontinued Internet Explorer and which is used in Office

An Iran-linked cyber-espionage group that has been found targeting critical infrastructure , energy and military sectors in Saudi Arabia and the United States two years ago continues targeting organizations in the two nations, Symantec reported on Wednesday. Widely known as APT33 , which Symantec calls Elfin , the cyber-espionage group has been active since as early as late 2015 and targeted a wide range of organizations, including government, research, chemical, engineering, manufacturing, consulting, finance, and telecommunications in the Middle East and other parts of the world. Symantec started monitoring Elfin's attacks since the beginning of 2016 and found that the group has launched a heavily targeted campaign against multiple organizations with 42% most recent attacks observed against Saudi Arabia and 34% against the United States. Elfin targeted a total of 18 American organizations in the engineering, chemical, research, energy consultancy, finance, IT and healthcar

Streamline your zero-trust access journey with three simple steps for high-risk, remote, and hybrid users.

Various cyber criminal groups and individual hackers are still exploiting a recently patched critical code execution  vulnerability in WinRAR , a popular Windows file compression application with 500 million users worldwide. Why? Because the WinRAR software doesn't have an auto-update feature, which, unfortunately, leaves millions of its users vulnerable to cyber attacks. The critical vulnerability (CVE-2018-20250) that was patched late last month by the WinRAR team with the release of WinRAR version 5.70 beta 1 impacts all prior versions of WinRAR released over the past 19 years. For those unaware, the vulnerability is "Absolute Path Traversal" bug that resides in the old third-party library UNACEV2.DLL of WinRAR and allows attackers to extract a compressed executable file from the ACE archive to one of the Windows Startup folders, where the malicious file would automatically run on the next reboot. Therefore, to successfully exploit this vulnerability and tak

It's not just the critical Drupal vulnerability that is being exploited by in the wild  cybercriminals to attack vulnerable websites that have not yet applied patches already available by its developers, but hackers are also exploiting a critical WinRAR vulnerability that was also revealed last week. A few days ago, The Hacker News reported about a 19-year-old remote code execution vulnerability disclosed by Check Point in the UNACEV2.dll library of WinRAR that could allow a maliciously-crafted ACE archive file to execute arbitrary code on a targeted system. WinRAR is a popular Windows file compression application with 500 million users worldwide, but a critical "Absolute Path Traversal" bug (CVE-2018-20250) in its old third-party library, called UNACEV2.DLL, could allow attackers to extract a compressed executable file from the ACE archive to one of the Windows Startup folders, where the file would automatically run on the next reboot. To successfully exploit the

Beware Windows users... a new dangerous remote code execution vulnerability has been discovered in the WinRAR software, affecting hundreds of millions of users worldwide. Cybersecurity researchers at Check Point have disclosed technical details of a critical vulnerability in WinRAR—a popular Windows file compression application with 500 million users worldwide—that affects all versions of the software released in last 19 years. The flaw resides in the way an old third-party library, called UNACEV2.DLL, used by the software handled the extraction of files compressed in ACE data compression archive file format. However, since WinRAR detects the format by the content of the file and not by the extension, attackers can merely change the .ace extension to .rar extension to make it look normal. According to researchers, they found an "Absolute Path Traversal" bug in the library that could be leveraged to execute arbitrary code on a targeted system attempting to uncompre

It is 2019, and millions of computers still either have at least one outdated application installed or run outdated operating systems, making themselves vulnerable to online threats and known security vulnerabilities/exploits. Security vendor Avast has released its PC Trends Report 2019 revealing that millions of users are making themselves vulnerable to cyber attacks by keeping outdated versions of popular applications on their computers. Probably the most overlooked vectors for any cyber attack is out-of-date programs, which most of the times, is the result of the users' laziness and company's administrators ignoring the security updates in a business environment as they can't afford the downtime. According to the report [ PDF ],  Adobe Shockwave tops the list of software that most user left outdated on their PCs, followed by VLC Media Player, Skype, Java Runtime Environment , 7-Zip File Manager, and Foxit Reader. The outdated software applications often provide an ope

Beware Windows Users! A new dangerous unpatched Zero-day Vulnerability has been detected in the latest version of WinRAR affects over millions of users worldwide. According to Mohammad Reza Espargham , a security researcher at Vulnerability-Lab , the stable version of WinRAR 5.21 for Windows computers is vulnerable to Remote Code Execution (RCE) flaw. WinRAR is one of the most popular utility program used to compress and decompress files with more than 500 Million installations worldwide. The WinRAR RCE vulnerability lie under the ' High Severity ' block, and scores 9 on CVSS ( Common Vulnerability Scoring System ). HOW WINRAR VULNERABILITY WORKS? Let's take a look at its actions. The vulnerability can be used by any attacker smartly to insert a malicious HTML code inside the " Text to display in SFX window " section when the user is creating a new SFX file. WinRAR SFX is an executable compressed file type containing one or more file

Imagine, You Open a Winrar archive of MP3 files, but what if it will install a malware into your system when you play anyone of them. WinRAR, a widely used file archiver and data compression utility helps hackers to distribute malicious code. Israeli security researcher  Danor Cohen (An7i)   discovered the WinRAR file extension spoofing vulnerability. WinRAR file extension spoofing vulnerability allows hackers to modify the filename and extension inside the traditional file archive, that helps them to hide binary malicious code inside an archive, pretending itself as '.jpg' , '.txt' or any other format. Using a Hex editor tool, he analysed a ZIP file and noticed that winrar tool also adds some custom properties to an archive, including two names - First name is the original filename (FAX.png) and second name is the filename (FAX.png) that will appear at the WINRAR GUI window. Danor manipulated the second filename and extension to prepare a special Z
