A phishing scheme is currently circulating involving the popular dropbox file sharing solution. Phishing emails containing links to Dropbox started circulating last month, and the emails purport to be “incoming fax reports” and the links do take users to Dropbox, but accessing and running the file results in users being hit by CryptoWall ransomware.
Once infected, the user’s default web browser opens to a page explaining that all files on the system have been locked and encrypted. Users are then urged to visit a site on the Tor network, which demands a $500 Bitcoin ransom that jumps to $1,000 after a few days.
If one of these emails makes it to your system please do not click on the link and contact USF Health IS with questions.
