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...

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...

security researchUNIXpassword crackingKen Thompson's 39-Year-Old BSD Password Cracked By Researchers
Have you heard that Unix co-founder Ken Thompson's 39-year old BSD password has finally been cracked? Learn more in an interesting The Hacker News article: . A 39-year-old login password ofKen Thompson, the co-creator of the UNIX operating system among, has finally been cracked that belongs to a BSD-based system, one of the original versions of UNIX, which was back then used by various computer science pioneers. In 2014, developer Leah Neukirchen spotted an interesting " /etc/passwd " file in a publicly available source tree of historian BSD version 3, which includes hashed passwords belonging to more than two dozens Unix luminaries who worked on UNIX development, including Dennis Ritchie, Stephen R. Bourne, Ken Thompson, Eric Schmidt, Stuart Feldman, and Brian W. Kernighan. Since all passwords in that list are protected using now-depreciated DES-based crypt(3) algorithm and limited to at most 8 characters, Neukirchen decided to brute-force them for fun and successfully cracked passwords (listed below) for almost everyone using password cracking tools like John the Ripper and hashcat.

And some Internet . . . . An online credit card processing company grudgingly admitted Thursday that a cache of passwords apparently stolen from its own system has resulted in hacker break-ins at hundreds - maybe thousands - of other servers across the Net. And some Internet service providers (ISPs) are angry that it took CCBill of Tempe, Ariz., nearly three days to finally admit to customers that there may be a security problem, despite substantial evidence that its clients appeared uniquely vulnerable to the rash of system break-ins first uncovered Monday. Dayne Jordan, a partner at Columbus, Ohio, Web-hosting company CompleteWeb, said attackers appear to have wielded the user IDs and passwords of legitimate ISP customers to enter Unix-flavored servers and install software capable of logging on to an Internet relay chat (IRC) channel to await further commands. Similar IRC-controlled "bots" have been used in the past to command small armies of zombie computers in distributed denial-of-service (DDoS) attacks.

A new way to attack wireless networks underscores the lack of security for PC owners using the airwaves to connect their computers, said security experts speaking at the Black Hat Briefings conference. On Thursday, Tim Newsham, a researcher for security firm @Stake, presented the details of weaknesses in the password system of wireless networks that could lead to a break in security in less than 30 seconds. The flaw is the third to be uncovered in the so-called Wired Equivalent Privacy, or WEP, protocol that supposedly secures wireless networks. Newer 128-bit wireless LAN (local area network) cards are fairly strong. But poorly chosen passwords can still be cracked with an old technique known as a dictionary attack: Using a list of common passwords and a dictionary of words, the potential intruder can try various combinations until the password is broken.
