In 2017, we saw digital extortion increasingly become cybercriminals’ first and foremost money-making modus operandi. It’s mostly due to ransomware — cybercriminals’ currently most popular weapon of choice, helping them in extorting cash from users all over the world and in hitting big businesses and organizations.

By infecting business-critical systems through their shotgun-style ransomware attacks and thus crippling enterprise day-to-day operations, cybercriminals managed to force big companies to bend to their will. Digital extortion has become the most successful moneymaking venture for cybercriminals, and the most effective in terms of the scale of their victims. Big or small, everyone gets hit, and everyone has to pay.

Trend Micro researchers detected a new SLocker variant that mimics the GUI of the WannaCry crypto-ransomware on the Android platform. Detected as ANDROIDOS_SLOCKER.OPSCB, this new SLocker mobile ransomware variant features new routines that utilize features of the Chinese social network QQ, along with persistent screen-locking capabilities.

SLocker, an Android file-encrypting ransomware first detected and analyzed in July, was found mimicking WannaCry’s GUI. Although Chinese police already arrested the ransomware’s alleged creator, other SLocker operators clearly remained unfazed.

Early this 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.

Over the course of 2016, ransomware operators trailed their sights on bigger targets—companies and organizations, both large and small—and raked in US$1 billion for their efforts.

Even before WannaCry reared its ugly head, companies and individuals worldwide have already been suffering the threat’s dire consequences—all documented in our report, “Ransomware: Past, Present, and Future.” After just one year, we saw a staggering 752% increase in the number of ransomware families.
