Flipper One project needs community help to build open Linux platform
Flipper Devices, the maker of the Flipper Zero pentesting tool, is asking the community to help build Flipper One, an open Linux platform for connected devices. Unlike Flipper Zero, which focuses on offline access control and radio technologies such as NFC, RFID, infrared, and sub-GHz communications, the Flipper One project is designed as a high-performance, Linux-based […]
Exploit released for new PinTheft Arch Linux root escalation flaw
A recently patched Linux privilege escalation vulnerability now has a publicly available proof-of-concept (PoC) exploit that allows local attackers to gain root privileges on Arch Linux systems. The vulnerability, named PinTheft by the V12 security team and still waiting to be assigned a CVE ID for easier tracking, exists in the Linux kernel’s RDS (Reliable […]
Exploit available for new DirtyDecrypt Linux root escalation flaw
A recently patched local privilege escalation vulnerability in the Linux kernel’s rxgk module now has a proof-of-concept exploit that allows attackers to gain root access on some Linux systems. Named DirtyDecrypt and also known as DirtyCBC, this security flaw was also autonomously found and reported by the V12 security team earlier this month, when the […]
Microsoft Exchange, Windows 11 hacked on second day of Pwn2Own
During the second day of Pwn2Own Berlin 2026, competitors collected $385,750 in cash awards after exploiting 15 unique zero-day vulnerabilities in multiple products, including Windows 11, Microsoft Exchange, and Red Hat Enterprise Linux for Workstations. The Pwn2Own Berlin 2026 hacking competition takes place at the OffensiveCon conference from May 14 to May 16 and focuses on enterprise technologies and […]
New Fragnesia Linux flaw lets attackers gain root privileges
Linux distros are rolling out patches for a new high-severity kernel privilege escalation vulnerability that allows attackers to run malicious code as root. Known as Fragnasia and tracked as CVE-2026-46300, this security flaw stems from a logic bug in the Linux XFRM ESP-in-TCP subsystem that can enable unprivileged local attackers to gain root privileges by writing arbitrary bytes […]
New critical Exim mailer flaw allows remote code execution
A critical vulnerability affecting certain configurations of the Exim open-source mail transfer agent could be exploited by an unauthenticated remote attacker to execute arbitrary code. Identified as CVE-2026-45185, the security issue impacts some Exim versions before 4.99.3 that use the default GNU Transport Layer Security (GnuTLS) library for secure communication. It is a user-after-free (UAF) flaw triggered during the TLS […]
Windows 11 and Microsoft Edge hacked at Pwn2Own Berlin 2026
On the first day of Pwn2Own Berlin 2026, security researchers collected $523,000 in cash awards after exploiting 24 unique zero-days. Today’s highlight was Orange Tsai’s attempt, who was awarded $175,000 in rewards after chaining 4 logic bugs to achieve a sandbox escape on Microsoft Edge. Windows 11 was also hacked three times by Angelboy and TwinkleStar03 (working with the DEVCORE Internship Program), Marcin Wiązowski, […]
JDownloader site hacked to replace installers with Python RAT malware
The website for the popular JDownloader download manager was compromised earlier this week to distribute malicious Windows and Linux installers, with the Windows payload found deploying a Python-based remote access trojan. The supply chain attack affects those who downloaded installers from the official website between May 6 and May 7, 2026 via the Windows “Download Alternative […]
New Linux ‘Dirty Frag’ zero-day gives root on all major distros
A new Linux zero-day exploit, named Dirty Frag, allows local attackers to gain root privileges on most major Linux distributions with a single command. Security researcher Hyunwoo Kim, who disclosed it earlier today and published a proof-of-concept (PoC) exploit, says this local privilege escalation was introduced roughly nine years ago in the Linux kernel’s algif_aead cryptographic algorithm interface. Dirty […]
New stealthy Quasar Linux malware targets software developers
A previously undocumented Linux implant named Quasar Linux (QLNX) is targeting developers’ systems with a mix of rootkit, backdoor, and credential-stealing capabilities. The malware kit is deployed in development and DevOps environments in npm, PyPI, GitHub, AWS, Docker, and Kubernetes. This could enable supply-chain attacks where the threat actor publishes malicious packages on code distribution […]
