Rockwell Advises Disconnecting Internet-Facing ICS Devices Amid Cyber Threats

May 22, 2024 ICS Security / Vulnerability
Rockwell Automation is urging its customers to disconnect all industrial control systems (ICSs) not meant to be connected to the public-facing internet to mitigate unauthorized or malicious cyber activity. The company  said  it's issuing the advisory due to "heightened geopolitical tensions and adversarial cyber activity globally." To that end, customers are required to take immediate action to determine whether they have devices that are accessible over the internet and, if so, cut off connectivity for those that are not meant to be left exposed. "Users should never configure their assets to be directly connected to the public-facing internet," Rockwell Automation further added. "Removing that connectivity as a proactive step reduces attack surface and can immediately reduce exposure to unauthorized and malicious cyber activity from external threat actors." On top of that, organizations are required to ensure that they have adopted the necessar

Foxit PDF Reader Flaw Exploited by Hackers to Deliver Diverse Malware Arsenal

Foxit PDF Reader Flaw Exploited by Hackers to Deliver Diverse Malware Arsenal

May 20, 2024 Vulnerability / Malware
Multiple threat actors are weaponizing a design flaw in Foxit PDF Reader to deliver a variety of malware such as Agent Tesla, AsyncRAT, DCRat, NanoCore RAT, NjRAT, Pony, Remcos RAT, and XWorm. "This exploit triggers security warnings that could deceive unsuspecting users into executing harmful commands," Check Point  said  in a technical report. "This exploit has been used by multiple threat actors, from e-crime to espionage." It's worth noting that Adobe Acrobat Reader – which is more prevalent in sandboxes or antivirus solutions – is not susceptible to this specific exploit, thus contributing to the campaign's low detection rate. The issue stems from the fact that the application shows "OK" as the default selected option in a pop-up when users are asked to trust the document prior to enabling certain features to avoid potential security risks. Once a user clicks OK, they are displayed a second pop-up warning that the file is about to execute

Defending Your Commits From Known CVEs With GitGuardian SCA And Git Hooks

May 20, 2024 Software Security / Vulnerability
All developers want to create secure and dependable software. They should feel proud to release their code with the full confidence they did not introduce any weaknesses or anti-patterns into their applications. Unfortunately, developers are not writing their own code for the most part these days. 96% of all software contains some open-source components, and open-source components make up between  70% and 90% of any given piece of modern software . Unfortunately for our security-minded developers, most modern vulnerabilities come from those software components.  As new vulnerabilities emerge and are publicly reported as  Common Vulnerabilities and Exposures  (CVEs), security teams have little choice but to ask the developer to refactor the code to include different versions of the dependencies. Nobody is happy in this situation, as it blocks new features and can be maddening to roll back component versions and hope that nothing breaks. Developers need a way to  quickly  determine if

New Wi-Fi Vulnerability Enables Network Eavesdropping via Downgrade Attacks

May 16, 2024 Vulnerability / Network Security
Researchers have discovered a new security vulnerability stemming from a design flaw in the IEEE 802.11 Wi-Fi standard that tricks victims into connecting to a less secure wireless network and eavesdrop on their network traffic. The  SSID Confusion attack , tracked as CVE-2023-52424, impacts all operating systems and Wi-Fi clients, including home and mesh networks that are based on WEP, WPA3, 802.11X/EAP, and AMPE protocols. The method "involves downgrading victims to a less secure network by spoofing a trusted network name (SSID) so they can intercept their traffic or carry out further attacks," Top10VPN  said , which collaborated with KU Leuven professor and researcher Mathy Vanhoef. "A successful SSID Confusion attack also causes any VPN with the functionality to auto-disable on trusted networks to turn itself off, leaving the victim's traffic exposed." The issue underpinning the attack is the fact that the Wi-Fi standard does not require the network na

(Cyber) Risk = Probability of Occurrence x Damage

May 15, 2024 Threat Detection / Cybersecurity
Here's How to Enhance Your Cyber Resilience with CVSS In late 2023, the Common Vulnerability Scoring System (CVSS) v4.0 was unveiled, succeeding the eight-year-old CVSS v3.0, with the aim to enhance vulnerability assessment for both industry and the public. This latest version introduces additional metrics like safety and automation to address criticism of lacking granularity while presenting a revised scoring system for a more comprehensive evaluation. It further emphasizes the importance of considering environmental and threat metrics alongside the base score to assess vulnerabilities accurately. Why Does It Matter? The primary purpose of the CVSS is to evaluate the risk associated with a vulnerability. Some vulnerabilities, particularly those found in network products, present a clear and significant risk as unauthenticated attackers can easily exploit them to gain remote control over affected systems. These vulnerabilities have frequently been exploited over the years, often ser
