Cybercriminals Use Eclipse Jarsigner to Deploy XLoader Malware via ZIP Archives

Cybercriminals Use Eclipse Jarsigner to Deploy XLoader Malware via ZIP Archives

Feb 20, 2025 Cybercrime / Malware
A malware campaign distributing the XLoader malware has been observed using the DLL side-loading technique by making use of a legitimate application associated with the Eclipse Foundation. "The legitimate application used in the attack, jarsigner, is a file created during the installation of the IDE package distributed by the Eclipse Foundation," the AhnLab SEcurity Intelligence Center (ASEC) said . "It is a tool for signing JAR (Java Archive) files." The South Korean cybersecurity firm said the malware is propagated in the form of a compressed ZIP archive that includes the legitimate executable as well as the DLLs that are sideloaded to launch the malware - Documents2012.exe, a renamed version of the legitimate jarsigner.exe binary, jli.dll, a DLL file that's modified by the threat actor to decrypt and inject concrt140e.dll, and concrt140e.dll, the XLoader payload The attack chain crosses over to the malicious phase when "Documents2012.exe...
Eclipse Foundation Revokes Leaked Open VSX Tokens Following Wiz Discovery

Eclipse Foundation Revokes Leaked Open VSX Tokens Following Wiz Discovery

Oct 31, 2025 Malware / Secure Coding
Eclipse Foundation, which maintains the open-source Open VSX project, said it has taken steps to revoke a small number of tokens that were leaked within Visual Studio Code (VS Code) extensions published in the marketplace. The action comes following a report from cloud security company Wiz earlier this month, which found several extensions from both Microsoft's VS Code Marketplace and Open VSX to have inadvertently exposed their access tokens within public repositories, potentially allowing bad actors to seize control and distribute malware, effectively poisoning the extension supply chain. "Upon investigation, we confirmed that a small number of tokens had been leaked and could potentially be abused to publish or modify extensions," Mikaël Barbero, head of security at the Eclipse Foundation, said in a statement. "These exposures were caused by developer mistakes, not a compromise of the Open VSX infrastructure." Open VSX said it has also introduced a toke...
Eclipse Foundation Mandates Pre-Publish Security Checks for Open VSX Extensions

Eclipse Foundation Mandates Pre-Publish Security Checks for Open VSX Extensions

Feb 04, 2026 Supply Chain Security / Secure Coding
The Eclipse Foundation, which maintains the Open VSX Registry, has announced plans to enforce security checks before Microsoft Visual Studio Code (VS Code) extensions are published to the open-source repository to combat supply chain threats. The move marks a shift from a reactive to a proactive approach to ensure that malicious extensions don't end up getting published on the Open VSX Registry. "Up to now, the Open VSX Registry has relied primarily on post-publication response and investigation. When a bad extension is reported, we investigate and remove it," Christopher Guindon, director of software development at the Eclipse Foundation, said . "While this approach remains relevant and necessary, it does not scale as publication volume increases and threat models evolve." The change comes as open-source package registries and extension marketplaces have increasingly become attack magnets, enabling bad actors to target developers at scale through a variet...

New HTTP/2 'MadeYouReset' Vulnerability Enables Large-Scale DoS Attacks

New HTTP/2 'MadeYouReset' Vulnerability Enables Large-Scale DoS Attacks

Aug 14, 2025 Server Security / Vulnerability
Multiple HTTP/2 implementations have been found susceptible to a new attack technique called MadeYouReset that could be explored to conduct powerful denial-of-service (DoS) attacks. "MadeYouReset bypasses the typical server-imposed limit of 100 concurrent HTTP/2 requests per TCP connection from a client. This limit is intended to mitigate DoS attacks by restricting the number of simultaneous requests a client can send," researchers Gal Bar Nahum, Anat Bremler-Barr, and Yaniv Harel said . "With MadeYouReset, an attacker can send many thousands of requests, creating a denial-of-service condition for legitimate users and, in some vendor implementations, escalating into out-of-memory crashes." The vulnerability has been assigned the generic CVE identifier, CVE-2025-8671 (CVSS score: 7.5), although the issue impacts several products, including Apache Tomcat ( CVE-2025-48989 ), F5 BIG-IP ( CVE-2025-54500 ), and Netty ( CVE-2025-55163 ).

BaitTrap: Over 17,000 Fake News Websites Caught Fueling Investment Fraud Globally

Jul 08, 2025 Financial Scams / Online Security
A newly released report by cybersecurity firm CTM360 reveals a large-scale scam operation utilizing fake news websites—known as Baiting News Sites (BNS)—to deceive users into online investment fraud across 50 countries. These BNS pages are made to look like real news outlets: CNN, BBC, CNBC, or regional media. They publish fake stories that feature public figures, central banks, or financial brands, all claiming to back new ways to earn passive income. The goal? Build trust quickly and steer readers toward professional-looking scam platforms like Trap10, Solara Vynex, or Eclipse Earn. Scammers use sponsored ads on Google, Meta, and blog networks to push traffic to these sites. Ads often carry clickbait headlines—“You won’t believe what a prominent public figure just revealed”—paired with official photos or national flags to make them feel legit. Clicking the ad directs users to a fake article, which then redirects them to a fraudulent trading platform. Many of these scams follow a...

Preventing your Cloud 'Secrets' from Public Exposure: An IDE plugin solution

Aug 25, 2021
I'm sure you would agree that, in today's digital world, the majority of applications we work on require some type of credentials – to connect to a database with a username/password, to access computer programs via authorized tokens, or API keys to invoke services for authentication. Credentials, or sometimes just referred to as 'Secrets,' are pieces of user or system-level confidential information that ought to be carefully protected and accessible to legitimate users only. We all know how important it is to keep these assets secure to prevent account misuse and breaches.  A reality check: How often do you make proactive efforts to protect these assets? Rarely, I'd say.  Among the worst mistakes a developer can make when it comes to application security is to accidentally commit confidential information publicly on the Internet. Surprisingly, secrets and credentials are accidentally leaked more often than you might expect, and there are intelligent tools that s...
