This site is an attempt at creating an online searchable repository of security related lists. What kind of lists? Well, pretty much any list that can be stored in a manner similar to “[type], [value]”. So for example, it is fairly easy to store a list of common passwords… “[passwords], [123456]” or a list of common Unix usernames… “[usernames], [root]”. The site can also store lists of other items such as common browser user agent strings, reverse shells which can be written on one line, one line back doors, known malicious IPs, and so on. There really is no limit to the types of data that can store and provide out as needed. latest exploits Search secunia’s vulnerability database
