Figure 1 is a snapshot of what the prep application looks like, complete with the general Help screen that the application provides. To make this preparation process more streamlined and less stressful, I also created an HTML Application (HTA) called CyberScanPrep.hta that ties these preparation requirements together. Create a hash list file that lists the 32-character strings of the intrusive files.Create a list of computers to be scanned.Define regular expressions of the intrusive filenames.This is an extremely sensitive and important process, and with that comes a good bit of preparation before running the main VBScript file. This secondary script is what actually performs the search activity against multiple servers-and because all the secondary scripts run simultaneously, it’s loosely considered to be multithreaded. This is not a true multithreaded application by definition but rather a pseudo-multithreaded application that calls a secondary script multiple times. To actually make this application function quickly and scan many systems at the same time it was necessary to make it a multithreaded application. #Express zip threat downloadYou can download Agent Ransack at The second utility is a public domain utility called MD5deep, which can produce MD5 hashes of files and can perform hash comparisons of the files against a list of known intrusive file hashes. The first utility is a freeware package from Mythicsoft called Agent Ransack, which is the search engine beneath the Cyber Threat Scanner application's hood that scans for the files you'e looking for. I made the choice to use these utilities instead of pure VBScript simply to overcome the lengthy processing time that would be involved if the application were written purely in VBScript. I created the Cyber Threat Scanner, which wraps two third-party utilities within a VBScript. #Express zip threat manualAside from a very resource-intensive effort to have the IT staff frantically perform manual scans of all systems, not much is available with the major Windows systems that allow you to run these scans easily and effectively across an entire domain. In many businesses nowadays, there is also the need to comply with security initiatives that require us to scan for specific files on occasion even if we have not necessarily experienced problems. In any event, there is a vital need to have a system in place that can scan your computer systems at a moment’s notice for intrusive files that might have entered your systems via virus attack, worms, hackers, malware, or other means. Of course we administrators are ever mindful of such events and help keep our systems safe by avoiding being logged on as administrators when performing non-administrative tasks such as opening our mail and accessing the Internet. I'm sure that most of us have very secure systems and might have never had an intrusion beyond the occasional desktop virus triggered by a user opening an enticing email or downloading questionable files over the Internet. So someone is bound to be the unwitting recipient of an attack or intrusion. Unfortunately, fixes are not available until shortly after a new intrusion has been discovered. In general, antivirus updates are only as current as known viruses. Even with the best maintained and accurate antivirus applications running, there is always a possibility of something getting through. For added protection, this revolutionary non-permeable membrane is laminated to a 4.5 ounce NOMEX IIIA outer shell, which provides excellent static dissipative performance and resists melting, dripping, and burning when exposed to high heat and fl ame.You never know when you’ll be called upon to do an immediate scan of your systems for known intrusive files.
