Security Trends Price Tag%201fedora security assessment

A Fedora contributor account recently came under scrutiny for apparently AI-generated activity that disrupted the project's bug tracker. . Questionable Bugzilla comments, flawed patches, and improperly closed or reassigned bugs forced maintainers to spend time cleaning up the fallout. There is no evidence that malware was deployed or a backdoor reached production, but the incident exposed a different problem. Open-source projects can be disrupted without compromising a single line of code....

Security Vulnerabilities Price Tag%201security advisory critical

Attackers are actively exploiting a high-severity vulnerability in Langflow , an open-source platform used to build and run AI workflows. . The flaw turns a file upload into a filesystem write, allowing a user-controlled file to escape the application's intended upload directory and land in locations Langflow was never supposed to touch. The vulnerable upload endpoint permits path traversal through crafted filenames. From there, the impact depends heavily on how the platform is deployed. A...

With npm v12 , dependency preinstall, install, and postinstall scripts will no longer execute automatically during package installation. Script execution will require explicit approval through new controls such as npm approve-scripts, with the change expected to arrive in July 2026. . The announcement targets a part of the software supply chain that has repeatedly appeared in package registry abuse, credential theft, and CI/CD compromise investigations. A single npm install could trigger code...

V8 Zero Day Chrome Esm H350
Security Vulnerabilities Price Tag%201security advisory zero-day

CISA added CVE-2026-11645 to its Known Exploited Vulnerabilities catalog after Google confirmed active exploitation of the flaw. The bug sits in V8, the JavaScript engine behind Chrome and Chromium. . That's where this gets more interesting. Most coverage will focus on Chrome because that's where the patch landed. But the affected component is V8. Chromium relies on it. Electron relies on it. Plenty of desktop software Linux users interact with every day relies on it too, often without much...

Network SecurityPrice Tag%201security advisory networking

For years, IPv4 was the only proxy type that really mattered for anyone running automation off a Linux box. IPv6 was the protocol everyone said they’d migrate to, but almost nobody actually did. In 2026, that’s finally starting to shift. . The problem is that most admins stick with IPv4 out of habit. They know it; it’s what their tooling defaults to, and they don’t see a reason to change. Some are overpaying for addresses they don’t need. Others would quietly break their scrapers, scripts, or...

Exploring LOIC: A Key Tool Behind DDoS Attacks in Cyber Activism

How was it that a loosely-coupled group of cyber-protestors could launch -- with varying degrees of success -- targeted distributed denial-of-service (DDoS) attacks against sites such as MasterCard, PayPal, PostFinance, and the website belonging to a Swedish prosecutor?. Turns out it's quite simple. All an attacker need do is download the open source network stress testing tool known as LOIC (the Low Orbit Ion Cannon) that is widely available. Launching an attack with LOIC is mind-numbingly easy: just point and shoot. LOIC will then flood the target with HTTP requests, UDP and TCP packets. Those participating in the pro-Wikileaks riots could operate on their own, or choose to connect their system to the "LOIC Hivemind" voluntary botnet that is centrally controlled by those behind Operation Payback. Since the launch of the attacks, LOIC has been downloaded nearly 70,000 times. Cyber protestors engaging in digital rioting such as web-site defacements, and denial-of-service attacks, and even inserting messages in malware have existed for some time. Such attacks being highly connected isn't new, either. They have been socializing on message boards and instantly c The link for this article located at CSO Online is no longer available. . The LOIC tool, short for Low Orbit Ion Cannon, is an accessible application mainly used by cyber activists to conduct DDoS attacks by overwhelming websites with traffic.
