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...

email securitymobile threatsmalicious linksMobile Users Targeted by QR Code Scams Through Spam Emails
Security researchers have spotted spam emails that point at URLs featuring embedded Quick Response codes (QR codes).. QR codes are a two-dimensional matrix barcode that can be scanned by a camera phone to link users directly to a website that can host any type of content, malicious or otherwise. By using QR codes (rather than links) as a jump-off point to spamvertised sites, spammers can disguise the ultimate destination of links as well as improving click-through rates. In particular, the approach helps when it comes to targeting mobile users. Spam messages spotted by Websense look like traditional pharmaceutical spam emails, with the twist that they link to a legitimate (but abused in this case) website, 2tag.nl. The legitimate web service allows users to create QR codes for URLs but has in this case been abused to create links that ultimately point to Canadian Pharmacy penis pill sites.

malwaredata theftprivacy breachNew iPhone/Privacy.A Malware Threatens Jailbroken Devices with Data Theft
Hot on the heels of the ikee worm, a second piece of iPhone-related malware has appeared, which enables hackers to connect to any device that has been jailbroken and still has an unchanged root password. Jailbreaking is a term used to define iPhones that have been hacked by users to enable software other than that available through the App Store to be installed. . The new malware takes advantage of the same vulnerability in the iPhone as the ikee worm and has been dubbed iPhone/Privacy.A by Mac security software house, Intego, which first discovered its existence. The company explained on its blog that hackers use the tool by installing it on either their own or compromised third-party Macs, PCs, Unix and Linux-based machines - or even on iPhones themselves. The program scans networks that are accessible to it and, when it finds a jailbroken iPhone, breaks into it, steals data including email, contacts and music files, and copies them..

The No. 1 threat to the sensitive data stored on your handheld device or smart phone remains physically losing the device, but other threats are looming on the handheld horizon. "When you send a defective PDA to the manufacturer for tech support, they usually give you a new one and then resell the old one," said John Girard, vice president and research director at Gartner Inc. "Buying dead machines is an ideal method of pursuing identity theft." What's more, 90% of mobile devices lack the protection necessary to ward off hackers, according to a recent strategic planning assumption conducted by Stamford, Conn.-based Gartner. . . .. The No. 1 threat to the sensitive data stored on your handheld device or smart phone remains physically losing the device, but other threats are looming on the handheld horizon. "When you send a defective PDA to the manufacturer for tech support, they usually give you a new one and then resell the old one," said John Girard, vice president and research director at Gartner Inc. "Buying dead machines is an ideal method of pursuing identity theft." What's more, 90% of mobile devices lack the protection necessary to ward off hackers, according to a recent strategic planning assumption conducted by Stamford, Conn.-based Gartner. "Most devices have IrDA, Bluetooth and wireless connections, and many of them aren't set up properly. You can just walk around with a connected device of your own and see what you can find," Girard said. Even if there are security settings activated by default on a device, users will often turn them off if they find them unintuitive to use, he said. "Security needs to be as transparent as possible to users," Girard said. Malicious Code While security researchers have developed "proof of concept" viruses for handheld devices and smart phones, nothing has been seen yet "in the wild," said David Perry, global director of education at antivirus developer Trend Micro Inc. in Cupertino, Calif.

Telecommunications companies spend as much as $8 billion a year fixing phones with programming errors, faulty mechanics and other problems. Now some are scrambling to prevent virus attacks that could cost carriers millions of dollars more in repairs and lost business. As more consumers begin surfing the Web and sending e-mail messages on cellphones and handheld devices, along comes a new worry: worms and viruses spread via Internet-enabled equipment. The problem is still small, with only a few cases reported globally so far. But as operating systems in cellphones become standardized, hackers are likely to begin focusing on vulnerabilities in those systems as they have with personal computers. And as cellphones and personal digital assistants connect to the Internet at ever faster speeds, more users will be able to download files with attachments, some of which may be infected. Asia, where high-speed networks and text messaging on mobile phones are common, is the most vulnerable to these threats. As carriers in Europe and North America adopt similar technology , they will confront similar hazards. The link for this article located at TechNewsWorld is no longer available. .

They love to hunt and sniff the air for signals emitted from the wireless handheld devices that you use to connect primarily with the WLAN. They then exploit the vulnerable network to launch an attack. In this article, Judith talks about who the cyber guerillas are and where you will most likely meet them. Additionally, she'll cover the various wireless security issues and describe how they use the tools of the trade to intercept, intrude upon, and attack the unprotected wireless traffic. Finally, a brief discussion about the VPN support, followed by a list of the shortcomings of mobile devices -- with suggested solutions to overcome them, of course. They are cyber spies that were the stuff of fiction you read a decade ago, but now they can spring right at you out of Jack's proverbial box if you are not careful -- especially when you use your Palm or other wireless mobile device on the road. They are the cyber version of the urban guerillas you read about in the newspapers. Cyber guerillas intend to deny or destroy wireless services for legitimate users, and as such, are more of a danger, even, than hackers. Hackers, or intruders, know ahead of time where the signals emanating from wireless networks (WLAN and mobile) are (see C. C. Palmer's "Ethical Hacking"). They use the trade tools to listen to actual packet flow in a vulnerable network and then break into the intended system targets. Cyber guerillas, on the other hand, search for signals in the spectrums and then use hacking tools to decrypt the transmissions. The link for this article located at IBM is no longer available. .
