Cybersecurity researchers have uncovered two local privilege escalation (LPE) flaws that could be exploited to gain root privileges on machines running major Linux distributions. The vulnerabilities , discovered by Qualys, are listed below - CVE-2025-6018 - LPE from unprivileged to allow_active in SUSE 15's Pluggable Authentication Modules ( PAM ) CVE-2025-6019 - LPE from allow_active to root in libblockdev via the udisks daemon "These modern 'local-to-root' exploits have collapsed the gap between an ordinary logged-in user and a full system takeover," Saeed Abbasi, Senior Manager at Qualys Threat Research Unit (TRU), said . "By chaining legitimate services such as udisks loop-mounts and PAM/environment quirks, attackers who own any active GUI or SSH session can vault across polkit's allow_active trust zone and emerge as root in seconds." The cybersecurity company said CVE-2025-6018 is present in the PAM configuration of openSUSE Leap ...

A new campaign is making use of Cloudflare Tunnel subdomains to host malicious payloads and deliver them via malicious attachments embedded in phishing emails. The ongoing campaign has been codenamed SERPENTINE#CLOUD by Securonix. It leverages "the Cloudflare Tunnel infrastructure and Python-based loaders to deliver memory-injected payloads through a chain of shortcut files and obfuscated scripts," security researcher Tim Peck said in a report shared with The Hacker News. The attack starts with sending payment- or invoice-themed phishing emails bearing a link to a zipped document that contains a Windows shortcut (LNK) file. These shortcuts are disguised as documents to trick victims into opening them, effectively activating the infection sequence. The elaborate multi-step process culminates in the execution of a Python-based shellcode loader that executes payloads packed with the open-source Donut loader entirely in memory. Securonix said the campaign has targeted the...

A new multi-stage malware campaign is targeting Minecraft users with a Java-based malware that employs a distribution-as-service (DaaS) offering called Stargazers Ghost Network . "The campaigns resulted in a multi-stage attack chain targeting Minecraft users specifically," Check Point researchers Jaromír Hořejší and Antonis Terefos said in a report shared with The Hacker News. "The malware was impersonating Oringo and Taunahi, which are 'Scripts and macros tools' (aka cheats). Both the first and second stages are developed in Java and can only be executed if the Minecraft runtime is installed on the host machine." The end goal of the attack is to trick players into downloading a Minecraft mod from GitHub and deliver a .NET information stealer with comprehensive data theft capabilities. The campaign was first detected by the cybersecurity company in March 2025. What makes the activity notable is its use of an illicit offering called the Stargazers Ghost...

For organizations eyeing the federal market, FedRAMP can feel like a gated fortress. With strict compliance requirements and a notoriously long runway, many companies assume the path to authorization is reserved for the well-resourced enterprise. But that’s changing. In this post, we break down how fast-moving startups can realistically achieve FedRAMP Moderate authorization without derailing product velocity, drawing from real-world lessons, technical insights, and the bruises earned along the way from a cybersecurity startup that just went through the process. Why It Matters Winning in the federal space starts with trust—and that trust begins with FedRAMP. But pursuing authorization is not a simple compliance checkbox. It’s a company-wide shift that requires intentional strategy, deep security investment, and a willingness to move differently than most startups. Let’s get into what that actually looks like. Keys to a Successful FedRAMP Authorization 1. Align to NIST 800-53 fro...

Cybersecurity researchers have exposed a previously unknown threat actor known as Water Curse that relies on weaponized GitHub repositories to deliver multi-stage malware. "The malware enables data exfiltration (including credentials, browser data, and session tokens), remote access, and long-term persistence on infected systems," Trend Micro researchers Jovit Samaniego, Aira Marcelo, Mohamed Fahmy, and Gabriel Nicoleta said in an analysis published this week. The "broad and sustained" campaign, first spotted last month, set up repositories offering seemingly innocuous penetration testing utilities, such as SMTP email bomber and Sakura-RAT, but harbored within their Visual Studio project configuration files malicious payloads that are designed to siphon sensitive data. Water Curse's arsenal incorporates a wide range of tools and programming languages, underscoring their cross-functional development capabilities to target the supply chain with "develope...
