"People who applied for a US visa in Switzerland complained about
receiving malware from an unknown person via Skype, posing as a US
government official guiding applications through the said process.
The victims said the person sent them a file named "US Travel Docs
Information.jar," but what rose suspicion was the fact that the Skype
account contained a spelling mistake (ustravelidocs-switzerland, notice
the extra "i"), and that made them realize it was not the official account.
Researchers from F-Secure investigated the case and announced they found
multiple such accounts, with misspelled names, targeting visa applicants
in several other countries as well."
