New York City
Family: ***Information Purposely Withheld***
AIM: Encryption (last publicly known sn)
Twitter: @anonymouSabu
Notes: Python, php, perl. Politically motivated even in years past. Active in AOL ‘hacking’ scene during 90s. Searches reveal several published vulnerablities, exploits and code from 90s and on, including AOL. Intelligent writer when publicly speaking but when in private conversations and non-public forums frequently uses slang normally associated with African-Americans and Puerto Ricans. Consistent dialect and word usage throughout old and new writings. Associated with other hackers from same era, many references to Nullbyte aka Haris Tahir. Nullbyte’s personal blog links to XavSec’s blog under the category ‘Lost Souls.’ Tahir’s blog makes direct reference to Anonymous & LulzSec, obviously a supporter (specifically of OpMalaysia among others). Pure-elite is seen in websites, mailing list posts and IRC. Gamer referenced by #ps3test chat logs linked to prvt.org. Prvt.org appears in several places. New York Giants fan, which coincides with NYCPug, NY perl/python lists, etc. Operated several websites and maintained personal blogs.  Several talks with insiders and self-proclaimed friends have described him as Puerto Rican and have provided the first name ‘Hector’. References to Hamas, Palestine and Middle East. Quote usages in Twitter feed have direct word-for-word correlation with older forum and mailing list posts.
