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...

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 advisorythreatVPNLinux And macOS Network Attack: VPN Session Hijack Risk
Researchers have discovered a security flaw in macOS, Linux, and several other operating systems that could let attackers hijack a wide range of virtual private network (VPN) connections. Learn more about this networking attack: . The bug, discovered by University of New Mexico researchers William J Tolley, Beau Kujath, and Jedidiah R. Crandall, lets a malicious access point or someone on the same network snoop on a user’s VPN session. The snooper can tell that they’re on a VPN and figure out what site they’re visiting. The researchers explain: This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel. The attack begins by working out the VPN client’s virtual IP address, which is the fake IP address that a VPN gives you when you use it to pretend that you’re somewhere else. It does this by sending SYN (short for synchronization) and ACK (short for acknowledgement) packets to the device. Because it doesn’t know the device’s exact address, it sends these packets to all addresses in the virtual IP space. When this noisy attack eventually hits the victim’s machine, it will respond with a reset (RST) packet that drops the connection.

Remember the O.MG cable? A project by self-taught electronics hacker _MG_ , it’s a malicious Lightning cable that looks just like the regular overpriced piece of wire that connects your iPhone to a computer. The cable is now about to hit mass distribution. Learn more: . Embedded in it is a tiny Wi-Fi transceiver that can operate as an access point or a wireless client. When the victim plugs it into their computer, an attacker within radio distance can connect to the cable with a mobile app and use it to manipulate the computer. An attacker can reach the O.MG cable from 300 feet away using Wi-Fi from a regular phone, but a suitable booster antenna connected to your computer or phone could enable a connection from even further away.

The FBI issued an alert this week warning that wireless Internet networks, often called Wi-Fi hotspots, are more vulnerable to hackers than most users probably realize. In South Florida, Wi-Fi hotspots are at airports, fast food restaurants, bookstores, coffee shops, sports bars, school campuses, malls, supermarkets -- just about everywhere. Several cities and neighborhoods in the region plan to eventually install networks for residents, too. How secure do you think is your local hotspot? Do you trust it to do your finances or other personal tasks via a coffee shop Wi-Fi access point?. The link for this article located at Red Orbit is no longer available. .

Several Cisco wireless access points (APs) are susceptible to a previously undetected security breach, the company said in an advisory issued this week. The APs will send Wired Equivalent Privacy static keys as clear text to simple network protocol (SNMP) servers under certain circumstances. Those who wish to break into the network can easily intercept and use the clear text keys. The specific APs with the vulnerability are Cisco's 1100, 1200 and 1400 series running the company's IOS software. The problem only occurs when the "snmp-server enable traps wlan-wep" command is enabled, the company said in its advisory.

Road warriors know the frustration: you're in a foreign city and want to find a Wi-Fi access point. Normally that means looking on the Internet for site directories that can tell you where the nearest hotspots are located, such as WiFinder or WiFiMaps. Most of the time, it's trial and error. Now, there is a much easier solution. US peripherals maker Kensington has introduced worlds first: a detector that will locate Wi-Fi networks. No more booting up your notebook to find a Wi-Fi signal. The small device detects 802.11b and 802.11g signals from up to 200 feet away and filters out other wireless signals, including cordless phones, microwave ovens and Bluetooth networks. Three lights indicate signal strength. For $29.95 that's seems a bargain. .

In a Wireless LAN (WLAN), things are different. Its physical medium is the electromagnetic spectrum, which exists everywhere and respects few boundaries. Wi-Fi is now available at two different frequencies-IEEE 802.11b at 2.4GHz and IEEE 802.11a at 5GHz-and both can suffer interference from neighboring networks and other sources.. . .. In a Wireless LAN (WLAN), things are different. Its physical medium is the electromagnetic spectrum, which exists everywhere and respects few boundaries. Wi-Fi is now available at two different frequencies-IEEE 802.11b at 2.4GHz and IEEE 802.11a at 5GHz-and both can suffer interference from neighboring networks and other sources. The only way to know for sure which will work best in a particular environment is to perform a comprehensive site survey before buying a single access point. Even if you have no intention of investing in Wi-Fi, knowing what's passing through your airwaves can still be useful. In addition to full-featured hardware and software analyzers, several vendors are pitching simpler, cheaper versions as security tools. These are designed to detect and track down rogue access points-WLAN base stations set up by employees without the IT department's knowledge. Almost all Wi-Fi hardware has its security features off by default, and the cheaper consumer-level models may not include any security at all, so these rogues can act as an open door into an otherwise well-protected network.
