Yet another incident which showcases that you should not explicitly trust user-controlled software repositories. One of the most popular Linux distros Arch Linux has pulled as many as three user-maintained software repository AUR packages after it was found hosting malicious code. Arch Linux is an independently developed, general-purpose GNU/Linux distribution composed predominantly of free and open-source software, and supports community involvement. Besides official repositories like Arch Build System (ABS), Arch Linux users can also download software packages from several other repositories, including AUR (Arch User Repository), a community-driven repository created and managed by Arch Linux users. Since AUR packages are user-produced content, Arch maintainers always suggest Linux users to carefully check all files, especially PKGBUILD and any .install file for malicious commands. However, this AUR repository has recently been found hosting malware code in several inst...

It's time to gear up your systems and software for the latest July 2018 Microsoft security patch updates. Microsoft today released security patch updates for 53 vulnerabilities, affecting Windows, Internet Explorer (IE), Edge, ChakraCore, .NET Framework, ASP.NET, PowerShell, Visual Studio, and Microsoft Office and Office Services, and Adobe Flash Player. Out of 53 vulnerabilities, 17 are rated critical, 34 important, one moderate and one as low in severity. This month there is no critical vulnerability patched in Microsoft Windows operating system and surprisingly, none of the flaw patched by the tech giant this month is listed as publicly known or under active attack. Critical Flaws Patched In Microsoft Products Most of the critical issues are memory corruption flaws in IE, Edge browser and Chakra scripting engine, which if successfully exploited, could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system in the context of the cur...

Adobe has released security patches for a total 112 vulnerabilities in its products, most of which have a higher risk of being exploited. The vulnerabilities addressed in this month's patch Tuesday affect Adobe Flash Player, Adobe Experience Manager, Adobe Connect, Adobe Acrobat, and Reader. None of the security vulnerabilities patched this month were either publicly disclosed or found being actively exploited in the wild. Adobe Flash Player (For Desktops and Browsers) Security updates include patches for two vulnerabilities in Adobe Flash Player for various platforms and application, as listed below. One of which has been rated critical (CVE-2018-5007), and successful exploitation of this "type confusion" flaw could allow an attacker to execute arbitrary code on the targeted system in the context of the current user. This flaw was discovered and reported to Adobe by willJ of Tencent PC Manager working with Trend Micro's Zero Day Initiative. Withou...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

Security researchers from Check Point Threat Intelligence Team have discovered the comeback of an APT (advanced persistent threat) surveillance group targeting institutions across the Middle East, specifically the Palestinian Authority. The attack, dubbed "Big Bang," begins with a phishing email sent to targeted victims that includes an attachment of a self-extracting archive containing two files—a Word document and a malicious executable. Posing to be from the Palestinian Political and National Guidance Commission, the Word document serves as a decoy to distract victims while the malware is installed in the background. The malicious executable, which runs in the background, act as the first stage info-stealer malware designed for intelligence gathering to identify potential victims (on the basis of what is unclear as of now), and then it accordingly downloads the second stage malware designed for espionage. "While the analysis...discloses the capabilities of ...

With the release of iOS 11.4.1, Apple has finally rolled out a new security feature designed to protect your devices against USB accessories that connect to the data port, making it harder for law enforcement and hackers to break into your iPhone or iPad without your permission. Dubbed USB Restricted Mode , the feature automatically disables data connection capabilities of the Lightning port on your iPhone or iPad if the device has been locked for an hour or longer, while the port can still be used for device charging. In other words, every time you lock your iPhone, a countdown timer of an hour gets activated in the background, which if completed, enables the USB restricted mode to prevent unauthorized access to the data port. Once the USB Restricted Mode gets activated, there's no way left for breaking into an iPhone or iPad without the user's permission. The feature would, no doubt, defeat law enforcement's use of special unlocking hardware made by Cellebrite ...
