If you believe you may have been affected by WAPDropper malware, you should first uninstall any suspicious applications and inspect your billing records to identify any unusual patterns.
We’ve come across our fair share of malware in the past that fraudulently subscribes users to in-app purchases on smartphones and other services. In the latest, researchers from Checkpoint have discovered a similar malware named WAPDropper.
