Criminals willing to travel thousands of miles are ensnaring hundreds of victims as they bring credit and debit card cloning schemes to the Twin Cities.
It's evidence, police and cyber security consultants said, of the ongoing fallout from major retail data breaches.
Suburban police are alerting residents to a rise in such cases while businesses and law enforcement alike try to figure out why the area has seen so many unwelcome visitors lately — and how to stop them.
"They are kind of like ghosts. They're in and they're out," said Eagan Police detective Desiree Schroepfer.
Police in Eagan have been able to arrest at least four pairs of suspects since April, tracing the cards they carried to more than 300 victims, according to charges. Investigators linked the biggest single case, with 180 suspected victims, to Home Depot's 2014 breach.
Though this summer's warnings have come from the south metro, authorities said that the area isn't alone. Many Minnesotans are beginning to notice — through bank statements or calls from police — that they are among the millions whose financial card information can be bought online with a username and about $20.
"Everyone has this," said Mark Lanterman, chief technology officer at Computer Forensic Services in Minnetonka. "Either law enforcement doesn't realize it or they're just beginning to understand the severity."
'Hackers are winning'
People using cloned cards often travel in pairs, flying in or driving rental cars and staying at hotels as they shuttle between cities, authorities said. Many go undetected because they use the duplicate cards near victims' hometowns to avoid raising banks' suspicions.
