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...

malwareLinuxnetwork scannerTeamTNT: New Linux Password Theft Capabilities in Crypto-Mining Malware
The TeamTNT threat group has updated Black-T - its crypto-mining worm - with Linux password-stealing capabilities and with an additional network scanner to help facilitate its spread to other vulnerable devices. . While known mostly for actively targeting Docker instances to use compromised systems for unauthorized Monero (XMR) mining, the group now shifted their tactics by upgrading their cryptojacking malware to also collect user credentials. As Unit 42 researchers found TeamTNT is hard at work boosting their malware's capabilities, this time adding memory password scraping capabilities via mimipy (with support for Windows/Linux/macOS) and mimipenguin (Linux support), two open-source Mimikatz equivalents targeting *NIX desktops. . TeamTNT's recent malware advancements include enhanced Linux password harvesting and network reconnaissance, targeting cloud and application servers more effectively.

It happens every day -- a sensitive document lies in the copier room, forgotten by the person who left it on the scanner. No big deal, right? Nobody else was able to read it.. Wrong, says Michael Sutton, a lab researcher at security vendor Zscaler. In fact, that document could easily be captured by an insider or an external hacker, without ever moving the paper from the scanner. In a blog posted yesterday, Sutton offered some hard evidence to suggest that networked scanners equipped with remote operations capabilities can easily be tapped to collect data from the sensitive documents that are run through them each day.

network securitynetwork scanneropen source toolUnderstanding Nmap: Applications And Ethical Considerations
Nmap (Network MAPper) is a network scanner written by Gordon Lyon. It is a free and open source tool and is available at insecure.org with versions for Windows and Linux and is ubiquitous in its use. Nmap can be (and is) used to for instance, scan for open ports on a remote server, to detect the OS run on the server, what all services are running on the remote server and so on. In the hands of a ethical hacker Nmap can be used for helping to audit a network but it's also used by attackers. So this brings up the question is software like Nmap ethical? .

security toolsvulnerability assessmentnetwork scannerGNessUs Unveiled: Fresh Open Source Fork of Network Scanner Tool
With news settling in that the makers of the network vulnerability scanner Nessus will not open source the next version of the software, the team behind the soon-to-be-renamed GNessUs project is growing fast and attracting attention. . Word broke on October 5 that Tenable Network Security, the company founded in 1998 to hold the copyright for Nessus, would not release Nessus 3.0 under the GNU General Public License (GPL). The company said it would continue to maintain the GPLed 2.2.x series, but would not open the source of the impending Nessus 3. By October 10, the GNessUs project launched a fork based on Nessus 2.2.5 and a community quickly began forming around it. Tim Brown, a penetration tester for Portcullis Computer Security Limited in the UK and founder of GNessUs, said the idea to fork the project came out of conversations with colleagues in the security industry in England. Brown said that the company's move to drop the GPL for Nessus 3 was no great surprise after Tenable split the plugin streams for the software and ignored concerns by Brown and others that vulnerabilities would be missed because people refused to check the streams for either fiscal or ethical reasons. "My fork is dedicated to that community," Brown said. The split last December created a three-part stream structure that offered a fee-based "Direct Feed" with the latest vulnerability checks available from Tenable, a delayed feed available to those who registered with Tenable and agreed to Tenable's license agreement for plugins, and a "GPL Feed" with plugins from the user community.

security toolsauditornetwork scannerEnhance IT Security With Auditor: Nmap, Nessus, And More Tools
The Auditor security collection is a GPL-licensed live CD based on Knoppix, with more than 300 security software tools. Auditor gives you easy access to a broad range of tools in almost no time. . How can Auditor help you with IT security? Many security engineers arrive on a client's site and find that the network documentation required for solving the task properly is incorrect or even obsolete. In Auditor's Scanning submenu you'll find the Nmap network scanner. You can choose the traditional shell version or Nmap FE, which provides a graphical front-end for Nmap. After you have gained a basic overview of the network you can use NBTScan, a NetBIOS name scanner, and Nessus, a vulnerability scanner. If the audit includes Web applications, try the Nikto and Amap application scanners. Let's say you've been called in to examine a possible compromised server, and until the integrity of the server has been established you are not allowed to install any forensic software or even take the server offline. You can take your Auditor CD and start running the chkrootkit utility to see if any known rootkits are installed on the server. If you find any suspicious activity, you can take a disk image with the dd command and examine it for any possible rootkits or strange processes. You can also use the Autopsy Forensic Browser, a graphical interface that can analyze Windows, Linux, and BSD file systems (NTFS, FAT, Ext2/3) to search for files. If you are analysing a Linux or Unix system, you can use Nibbler to extracts known offsets from binaries to find hidden trojan horses.
