Federal prosecutors in California have filed criminal charges against four employees of Adconion Direct, an email advertising firm, alleging they unlawfully hijacked vast swaths of Internet addresses and used them in large-scale spam campaigns. KrebsOnSecurity has learned that the charges are likely just the opening salvo in a much larger, ongoing federal investigation into the company’s commercial email practices.
A story published here last week warned readers about a vast network of potentially malicious Web sites ending in “.cm” that mimic some of the world’s most popular Internet destinations (e.g. espn[dot]cm, aol[dot]cm and itunes[dot].cm) in a bid to bombard hapless visitors with fake security alerts that can lock up one’s computer. If that piece lacked one key detail it was insight into just how many people were mistyping .com and ending up at one of these so-called “typosquatting” domains.
On March 30, an eagle-eyed reader noted that four years of access logs for the entire network of more than 1,000 dot-cm typosquatting domains were available for download directly from the typosquatting network’s own hosting provider. The logs — which include detailed records of how many people visited the sites over the past three years and from where — were deleted shortly after that comment was posted here, but not before KrebsOnSecurity managed to grab a copy of the entire archive for analysis.
