Life
Armin first came into the public eye in 2007 from his exposure of the
RBN (Russian Business Network). Throughout 2007, via a dedicated blog entitled RBNExploit, he provided reports and analysis on the undercover operations of the RBN criminal gang, despite constant DDoS attempts and artificially-created mirror websites.
It was via the RBN blog that Armin provided the first reports of cyber attacks, used in conjunction with the invasion of Georgia by Russian troops, three days in advance of the attack in August 2008.

The Reports
In August 2008, Jart Armin, via HostExploit, published a report "

website hosting provider deliberately allowed cyber criminals to use its services. This brought about the shutdown of Atrivo with a related 10% drop in botnet and spam activity worldwide.
In November 2008, Armin published a further report, "

McColo by revealing the web hosting service provider to be deliberately funding criminal activities and illegal child sexual abuse content.
The cybercriminal activities of
EstDomains were tracked by Armin and his allies in RBN blog postings and HostExploit reports.
Exposing the link between the RBN and EstDomains in the October 2008 report entitled "RBN – Farewell to EstDomains" lead to the operational closure of the
EstDomains business and to its customer base moving to the Asian registrar Directi.
In a joint venture with Andrew Martin of MartinSecurity.net, Armin issued the report "Real Host Latvia – RBN Resurgence or Clone?" in August 2009, providing further evidence of continuing RBN involvement in internet fraud.
Telia, the hosting registrar, suspended all involvement with Real Host when provided with the evidence contained within the report.
In November 2009, in another joint venture with Andrew Martin and Scott Logan, Jart Armin and HostExploit released a report called "MALfi, A Cybercrime International Report - A Silent Threat". The report describes how hackers and cybercriminals use blended attacks - a combination of
RFI (remote file inclusion),
LFI (local file inclusion), cross-server attack, and
RCE (remote code execution) - to compromise websites and servers.
In August 2010, Armin and the HostExploit team released a report providing an analysis of
Demand Media's persistent position as "No 1 Bad Host" in HostExploit’s Top 50 Bad Hosts list.
