SAN FRANCISCO, May 13, 2014 /PRNewswire/ -- Cheetah Mobile
(NYSE: CMCM), the security and utility app developer (formerly KS
Mobile), today issued the free CM CryptoLocker Cleaner app to
protect Android smartphone users from the malware known as
"CryptoLocker," a ransomware known to target Windows PC computers
that has now evolved to also target mobile Android devices.
Android users who have been infected with CryptoLocker Malware
on their mobile devices can use CM CryptoLocker Cleaner to unlock
their devices from the malware. CM CryptoLocker Cleaner is
available for free at Google Play.
Cheetah Mobile's CM Security Research Lab says the
"CryptoLocker" mobile threat (discovered as
"Android-Trojan.Koler.A") to Android users is on the rise in the US
in particular, where over 90% of the infection currently resides -
a 300% increase over the past several days.
How the CryptoLocker Ransomware works:
- Android user unknowingly download an APK file that is infected
(possible when users download apps from unsecure sources, outside
of Google Play)
- The malware takes control of the Android device, preventing you
from using normal functions until it's removed.
- The Android user receives a message claiming to be from a law
enforcement division, accusing the user of illegal act(s). See
screenshot.
- Then, the malware employs a very strong social engineering
element to try to get users to part with ransom money.
- Once the device is infected by the Cryptolocker malware, popups
appear on the home screen page, notifying users that they tried to
access porn. The popup claims that, as a result of their behavior,
the local police will block their device unless users pay a fine of
300 USD via untraceable online
payment systems.
Android users can prevent their mobile devices from future
infections by downloading Cheetah Mobile's CM Security, a free
antivirus and mobile security application that comprehensively
detects viruses, Trojans, malware, spyware, and adware on Android
mobile phones and tablets. CM Security is available for free
at Google Play.
