VERY IMPORTANT

Early last month, a new variant of mobile ransomware SLocker (detected by Trend Micro as ANDROIDOS_SLOCKER.OPST) was detected, copying the GUI of the now-infamous WannaCry. The SLocker family is one of the oldest mobile lock screen and file-encrypting ransomware and used to impersonate law enforcement agencies to convince victims to pay their ransom. After laying low for a few years, it had a sudden resurgence last May. This particular SLocker variant is notable for being one of the first Android file-encrypting ransomware, and the first mobile ransomware to capitalize on the success of the previous WannaCry outbreak.
