Piracy isn’t the only illegal activity taking place on file lockers. Recent research has demonstrated that hackers are using file lockers and streaming sites to exfiltrate stolen credit card numbers and other stolen data from their targets.
In a recent article published at Dark Reading, the methods used by hackers to exfiltrate data via video streaming sites were examined in detail. However this activity also takes place on file lockers.
Hackers who have stolen credit card, financial or other data need a way to exfiltrate that data without revealing their final destination for the data. So in a clever manoeuvre the hackers will embed stolen data into regular movie files and then upload them onto file locker services. Then once the data is in place, the hackers will then exfiltrate that data just as a normal file locker user would download files. Once the data has been retrieved the original files are deleted from the file locker.
