PCPJack Worm Targets Cloud Infrastructure, Steals Credentials
A fresh malware campaign, dubbed PCPJack, is targeting cloud infrastructure, stealing credentials and wreaking havoc on Linux-based systems with a sophisticated framework that installs hidden working directories and establishes persistence. This alarming attack bears striking similarities to earlier TeamPCP/PCPCat campaigns, raising concerns about its potential impact.
Linux Flaw Exposes Millions to Local Privilege Escalation
A critical Linux flaw, known as Copy Fail, has been discovered, exposing millions to potential local privilege escalation attacks - a vulnerability that highlights a deterministic logic error in the Linux kernel's cryptographic subsystem. This flaw, tracked as CVE-2026-31431, was publicly disclosed on April 29, 2026.
CISA Warns of Actively Exploited Linux Root Access Bug
A nine-year-old Linux kernel bug, known as Copy Fail, is being actively exploited in the wild, allowing unprivileged users to gain root access with a simple 732-byte Python-based exploit. The Cybersecurity and Infrastructure Security Agency has added this vulnerability to its Known Exploited Vulnerabilities catalog, warning of potential security risks.
cPanel flaw fuels mass Sorry ransomware attacks
A critical flaw in cPanel, tracked as CVE-2026-41940, has been exploited in a massive ransomware campaign, compromising at least 44,000 IP addresses. This alarming attack has already been used in the wild as a zero-day, with threat actors accessing control panels and wreaking havoc on web hosting systems.
AI Uncovers Nine-Year-Old Linux Kernel Zero-Day Flaw
A shocking nine-year-old flaw in the Linux kernel, dubbed "Copy Fail," allows unprivileged users to secretly alter readable files and potentially gain root access to affected systems. This vulnerability, tracked as CVE-2026-31431, has been lurking in Linux kernels since 2017, putting countless machines at risk.
VECT 2.0 Ransomware Exposes Flaw, Irreparably Destroys Large Files
Meet VECT 2.0, a malicious ransomware that doesn't just hold your files hostage - it destroys them, leaving you with no way to recover even if you pay up. This cunning malware wreaks havoc on large files across Windows, Linux, and ESXi hosts, causing irreversible damage.
SUSE's European Sovereignty Pitch Tested by $6 Billion Sale Talks
SUSE's pitch for European digital sovereignty is being put to the test as its majority stakeholder, EQT, explores a potential $6 billion sale that could see the Linux vendor fall under US ownership. This development creates an intriguing contradiction for a company that's deeply rooted in European values.
AI-Powered Vulnerability Discovery Outpaces Remediation
The AI-powered Mythos model discovered a staggering number of vulnerabilities, including a 27-year-old bug in OpenBSD and a four-bug exploit chain that bypassed browser and OS defenses, with fewer than 1% of these vulnerabilities patched. This led Anthropic to delay a public release and share the findings with tech giants like Apple and Microsoft to prioritize patching.
Harvester Expands Linux Arsenal with GoGra Backdoor in South Asia
Harvester's Linux arsenal just got a boost with the deployment of the GoGra backdoor in South Asia, enabling the threat actor to sneak past traditional network defenses by hijacking legitimate Microsoft Graph API and Outlook mailboxes. This latest move is linked to Harvester's earlier espionage campaigns targeting key sectors in the region.
Impersonator Exploits Slack to Target Linux Developers
