Antisec and Anonymous are the hacker groups that involve in hacktivism activities and they are playing with law enforcement agencies from a long time. Previously they have released different dumps that are related with the high profile companies and organization including government agencies and military information. Anonymous claim Syrian MOD web site defacement before.
This time they have released another dump 7.4 GB of US law enforcement web sites on Bittorrent that contains email, personal details, training videos and other data from around 70 law enforcement agencies in the US. The data has been stolen from 76 websites of 11 states and they are hosting on the same server that is compromised.
These hackers use their own exploits for the vulnerabilities which allow them to root the server of law enforcement web sites. Brooks-Jeffrey Marketing (BJM) is a server hosting company that closed the sites down while it took action. That action appears to have been to install a new server and move the web hosting software with, said Anonymous, its backdoors, over to the new server. “In less than an hour, we rooted the new server and defaced all 70+ domains” said an Antisec statement.
