This investigation by the Agari Cyber Intelligence Division into the cybercriminal group we’ve named Scattered Canary offers unprecedented visibility into eleven years of fraud and criminal activities , and the growth of a 419 startup into a fully operational BEC business . While this criminal organization’s activities now center around BEC , and extend to romance scams , credit card fraud , check fraud , fake job listings , credential harvesting , tax schemes , and more , these actors came from much humbler beginnings , starting with basic Craigslist scams in 2008 .

Many feel that they have a home team advantage living in Nigeria , where they are free to pay off law enforcement to look the other ACT . Scattered Canary’s fraudulent history can be traced as far back as October 2008 , when the group first arrived on the cybercriminal circuit . By March 2016 , one of Scattered Canary’s members had built enough trust with a romance victim—who we’ll call Jane—that she became a frequent source of new mule accounts for the group . Alpha’s early role was fairly simple: engage with individuals , who he chose based on the goods they were selling , and then provide personal shipping addresses back to Omega . By all accounts , late 2015 was the beginning of BEC for Scattered Canary . The first type of attack Scattered Canary pivoted to was credential phishing . Between July 2015 and February 2016 , Scattered Canary’s primary focus seemed to be mass harvesting general credentials using a Google Docs phishing page . In the first few months of their credential phishing ventures , Scattered Canary’s sights were mostly set on Asian targets—Malaysia and Japan , in particular . In November 2015 , the group started to focus on North American users , mostly in the United States . This activity ceased in February 2016 , likely because the men who made up Scattered Canary began to focus on honing their BEC skills .
