Join NetWars: Capture The Flag Cyber Challenge for Hackers

Like computers themselves, the Cyber Challenge is simple on the outside and complicated on the inside. The first round of the game began in June, and winners of the earlier games were brought to Washington to compete in NetWars.. In its simplest form, NetWars is an online version of Capture the Flag, with competitors vying to penetrate and take control of target computer systems and then protect them from other intruders. The game begins when a player downloads an image and must find a hidden key within the image. They use that key to enter an online environment and use their knowledge of security vulnerabilities to exploit its system, leaving their name or "handle" in various areas. A moderator threw a series of computer hurdles and roadblocks to further challenge the hackers and test their knowledge about computer vulnerabilities. NetWars differs from other Capture the Flag competitions in that it also rewards hackers for defending computers, said Josh Gimer, 22, a graduate student at Colorado Tech. He likens it more to King of the Hill. The link for this article located at CNN is no longer available. . CyberQuest is an exciting virtual Escape Room adventure that evaluates participants on their skills in breaching systems and protection strategies..

New Hacker Tools Target Network Weaknesses for Unauthorized Access

Well, thanks to lax security by vendors and network administrators, not to mention an underground network of devious and talented souls churning out user-friendly cracking tools, it's never been easier. The latest such tool to hit the Internet is called SMBRelay, . . . . Well, thanks to lax security by vendors and network administrators, not to mention an underground network of devious and talented souls churning out user-friendly cracking tools, it's never been easier. The latest such tool to hit the Internet is called SMBRelay, and it exploits a well-known flaw in Microsoft Corp.'s Windows NT and Windows 2000 software that enables an attacker to hijack NetBIOS connections. Gaining unauthorized access to networks used to be a game that only a small handful of gifted crackers with a lot of time on their hands could play. They would laboriously comb the Internet for vulnerable machines, poke and prod until they found a way in, and then execute whatever attack they had in mind. The link for this article located at ZDNet / eWeek is no longer available. . The proliferation of sophisticated hacking tools has made it simpler for cybercriminals to take advantage of vulnerabilities in security systems..
