![]() ![]() "For example, they believed a scanner operator would be able to detect a block of C-4 plastic explosive material under a person's clothes because it would cast an X-ray shadow. "I was not surprised that there were security vulnerabilities in the system because they made a lot of faulty assumptions," Checkoway says. By figuring out how the software worked, he says, the team could see how a criminal might tamper with the programming or find blind spots that would make it possible for weapons and other unwanted items to go undetected. The eight authors of the paper include faculty members, graduate students, and other scholars from the University of California, San Diego the University of Michigan and Stephen Checkoway, an assistant research professor in the Department of Computer Science in Johns Hopkins' Whiting School of Engineering.Īlso see: Researchers Easily Slipped Weapons Past TSA's X-Ray Body Scanners ( Wired)Ĭheckoway reverse-engineered the software that ran the operator console for the scanning equipment. Secure 1000 scanners were removed from airports in 2013 due to privacy concerns, but they are now being repurposed for use in jails, courthouses, and other government facilities. "We find that the system provides weak protection against adaptive adversaries: It is possible to conceal knives, guns, and explosives from detection by exploiting properties of the device's backscatter X-ray technology," the scientists write. The results of their evaluation are described in a paper scheduled for public presentation Thursday at the USENIX Security conference in San Diego. They were also able to modify the scanner's operating software so it presented an "all-clear" message to the operator even when contraband was detected. In laboratory tests, the team was able to conceal firearms and plastic explosive simulants from the Rapiscan Secure 1000 scanner. What the researchers found was not particularly reassuring. ![]() They bought a surplus unit on eBay in 2012. The team members conducted the first independent security evaluation of the Rapiscan Secure 1000 full-body scanner, which was widely deployed at U.S. 380 ACP pistol taped above the subject’s knee. w00tw00t.at. caption: Carefully placed metallic objects can be invisible against the dark background to the Secure 1000 scanner.Even more importantly, only use safe scripts that have a good reputation for security on the Internet, and be sure that you always check the parent sites for your scripts at least once a month for updates and bug fixes. Be sure you have your file and directory permissions set properly. Your best defense is to learn what you can do to keep your files, directories, and scripts safe from hackers. Keep your code clean! Most web sites are attacked in one way or another almost every day. These entries can be followed by other brute-force entries (the actual hack attempts). It only means that someone has been scanning your server for potential vulnerabilities using a web vulnerability scanner. ![]() ![]() In my MYSQl log I see these lines - how does that realte to what has happened?

No data's missing, but I'm really not feeling well over the spook of those weird entries - how can I check if someone's been inside my system? I restarted it, and everything LOOKS normal. OK - on further investigation - for some reason the mysql service was shut down. I'm seeing these entries in my access log as the last two before a series of 500 error messages, It's related to the DB but I haven't found out the exact error yet. ![]()
