The Year Targeted Phishing Went Mainstream

A story published here on July 12 about a new sextortion-based phishing scheme that invokes a real password used by each recipient has become the most-read piece on KrebsOnSecurity since this site launched in 2009. And with good reason — sex sells (the second most-read piece here was my 2015 scoop about the Ashley Madison hack).

But beneath the lurid allure of both stories lies a more unsettling reality: It has never been easier for scam artists to launch convincing, targeted phishing and extortion scams that are automated on a global scale.

Dot-cm Typosquatting Sites Visited 12M Times So Far in 2018

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.

Omitting the “o” in .com Could Be Costly

Take care when typing a domain name into a browser address bar, because it’s far too easy to fat-finger a key and wind up somewhere you don’t want to go. For example, if you try to visit some of the most popular destinations on the Web but omit the “o”… Continue reading Omitting the “o” in .com Could Be Costly
