system security Linux network The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Server Securityopen-source Linux administration
open-source Linux administration Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

Vendors/Productssecurity breach linux
security breach linux A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Security Trends access control multi-tenant
access control multi-tenant Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

Vendors/Productsincident response cloud security
incident response cloud security Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

arbitrary code executionsecurity flawdata theftPoet Tool: Data Theft via JavaServer Faces Security Flaw
Researchers have released software that exposes private information and executes arbitrary code on sensitive websites by exploiting weaknesses in a widely used web development technology.. Short for Padding Oracle Exploitation Tool, Poet is able to decrypt secret data encrypted by the JavaServer Faces web development framework without knowing the secret key. Attackers can use the technique to access private customer data on websites operated by banks, e-commerce companies and other businesses, according to a paper (PDF) released in February by researchers Juliano Rizzo and Thai Duong. In some cases, the exploit can be used to run malicious software on the underlying server. Released Monday, Poet exploits a well-known vulnerability in the way many websites encrypt text stored in cookies, hidden HTML fields and request parameters. The text is designed to help servers keep track of purchases, user preferences and other settings while at the same time ensuring account credentials and other sensitive data can't be intercepted. By modifying the encrypted information and sending it back to the server, the attackers can recover the plaintext for small chunks of the data, allowing them to access passwords and restricted parts of a webserver.

security issuenetwork attackssl protocolNew SSL Protocol Threat Uncovered by Leviathan Security Group
A Seattle computer security consultant says he's developed a new way to exploit a recently disclosed bug in the SSL protocol, used to secure communications on the Internet. The attack, while difficult to execute, could give attackers a very powerful phishing attack.. Frank Heidt, CEO of Leviathan Security Group, says his "generic" proof-of-concept code could be used to attack a variety of Web sites. While the attack is extremely difficult to pull off -- the hacker would first have to first pull off a man-in-the-middle attack, running code that compromises the victim's network -- it could have devastating consequences. The attack exploits the SSL (Secure Sockets Layer) Authentication Gap bug, first disclosed on Nov. 5. One of the SSL bug's discoverers, Marsh Ray at PhoneFactor, says he's seen a demonstration of Heidt's attack, and he's convinced it could work. "He did show it to me and it's the real deal," Ray said. The link for this article located at Network World is no longer available. .

A technique that exploits the way in which Web browsers store recently viewed data could compromise privacy by allowing an attacker to check what sites a Netizen has visited recently. Called a "timing attack," the exploit allows an unethical Web site to play 20 questions (or more) with a user's browser and check whether the surfer has recently viewed sites from a predetermined list. "The attacks allow any Web site to determine whether or not each visitor... has recently visited some other site (or set of sites)," said Princeton University computer science professor Edward Felten and graduate student Michael Schneider in a paper published at a technical conference last month. "The attacker can do this without the knowledge or consent of either the user or the other site." The link for this article located at ZDNet is no longer available. .
