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...

After a damning report from the Pentagon's chief weapons tester about cyber threats earlier this year, the US Defense Department is stepping up efforts to protect its networks with a new system to help spot flaws. . The aim of the system is to identify vulnerabilities in the military's networks, weapons systems and installations so that officials can set priorities for fixing them, US Cyber Command deputy commander Air Force lieutenant general Kevin McLaughlin told Reuters. .

security incidentinternet attacknetwork breachUS Systems Breached: Investigators Pursue Widespread Network Attack
The incident seemed alarming enough: a breach of a Cisco Systems network in which an intruder seized programming instructions for many of the computers that control the flow of the Internet. Now federal officials and computer security investigators have acknowledged that the Cisco break-in last year was only part of a more extensive operation - involving a single intruder or a small band, apparently based in Europe - in which thousands of computer systems were similarly penetrated. . Investigators in the United States and Europe say they have spent almost a year pursuing the case involving attacks on computer systems serving the American military, NASA and research laboratories. The break-ins exploited security holes on those systems that the authorities say have now been plugged, and beyond the Cisco theft, it is not clear how much data was taken or destroyed. Still, the case illustrates the ease with which Internet-connected computers - even those of sophisticated corporate and government networks - can be penetrated, and also the difficulty in tracing those responsible. Government investigators and other computer experts sometimes watched helplessly while monitoring the activity, unable to secure some systems as quickly as others were found compromised. The case remains under investigation. But attention is focused on a 16-year-old in Uppsala, Sweden, who was charged in March with breaking into university computers in his hometown. Investigators in the American break-ins ultimately traced the intrusions back to the Uppsala university network. The link for this article located at The New York Times is no longer available. .

security advisoryremote accesscyber threatU.S. Military Systems Compromised: Gary McKinnon Indicted for Hacking
Gary McKinnon, the Briton indicted this week for hacking into scores of U.S. military computers, left behind few clues on the compromised systems of his victims. But download log files from a Wisconsin software firm may have led investigators straight to his London door. . .. Gary McKinnon, the Briton indicted this week for hacking into scores of U.S. military computers, left behind few clues on the compromised systems of his victims. But download log files from a Wisconsin software firm may have led investigators straight to his London door . In an apparent effort to avoid detection, McKinnon, 36, installed copies of a commercial remote-access utility called RemotelyAnywhere on Navy and other military systems he allegedly hacked last year. The unusual strategy almost worked. Unlike underground "backdoor" utilities like NetBus or Back Orifice, the popular RemotelyAnywhere program doesn't trigger antivirus software. For nearly a year, McKinnon was able to control a vast network of defense computers without detection, authorities said. But McKinnon's choice of RemotelyAnywhere ultimately may have been his undoing. Using a personal computer connected to an ISP in England, McKinnon downloaded a trial copy of RemotelyAnywhere in March 2001 from a server maintained by Binary Research, the Milwaukee-based distributor of RemotelyAnywhere. To obtain a special code to unlock the demonstration software, McKinnon also provided his girlfriend's e-mail address, Binary officials said. The Internet protocol address left in Binary's server log files from McKinnon's download, along with the e-mail address, gave investigators two "very critical" pieces of evidence, said Binary vice president Jim Szopinski. "Not only were his finger prints on military computers, they were on ours as well," said Szopinski, who also noted in an affidavit that the version of RemotelyAnywhere McKinnon downloaded matched the one installed on the hacked military systems. This week McKinnon, an unemployed system administrator, was indicted infederal courts in Virginia (PDF) and New Jersey on eight counts of computer crimes. New Jersey Assistant U.S. Attorney Scott Christie said he was unable to comment on the evidence that led investigators to McKinnon, citing grand-jury restrictions. Szopinski said McKinnon likely obtained a "crack" or illegal license key to unlock copies of RemotelyAnywhere and place them on numerous computers. Once installed on a Windows system, RemotelyAnywhere allows remote users to access files and control a computer through a Web browser. Although investigators said the indicted hacker used the nickname "Solo" when online, according to Christie there was "no evidence" to show that he was the same hacker who took credit for defacing several high-profile sites in the late 1990s, including an Air Force site. Chris McNab, a security analyst who uses the online handle "So1o" and is currently technical director for Matta Security, a London-based consulting firm, said in a telephone interview that he was not aware someone else was using his nickname until McKinnon's indictment. "This guy is able to use whatever alias he wants. But the fun and games I used to have under that handle was almost four years ago," said McNab. Authorities are seeking the extradition of McKinnon, who is not currently in police custody, Christie said. McKinnon faces on each count a maximum sentence of 10 years in prison and a $250,000 fine. Szopinski said U.K. authorities told him that McKinnon did not appear to be linked to terrorists. Instead, investigators characterized the hacker as "a conspiracy theorist" who "seemed to think that the government was controlling all sorts of things," Szopinski said.
