FakeSpy Uses SMS Phishing Disguised as Postal Service Messages to Spread Malware
Malware is targeting Android users across the globe with a smishing campaign. The malware, called FakeSpy, sends fake SMS text messages that are supposedly delivery updates from the postal service to trick users into clicking on a malicious link. The malware steals information from infected phones including financial account information and contact lists according to cyber security researchers at Cybereason.
FakeSpy malware sends SMS phishing (called “smishing”) text messages to potential victims. The SMS messages are crafted to look like they were sent by a number of postal services and contain delivery update information. Fake smishing messages from The U.S. Postal Service, the U.K. Royal Mail, Germany’s Deutsche Post, Switzerland’s Swiss Post, France’s La Poste, Taiwan’s Chunghwa Post have all been used to trick victims. Private delivery companies such as Japan Post, Yamato Transport, and Deutsche Post DHL Group are also being impersonated in this smishing attack.
The information for the attack most likely was gleaned from social engineering.
“FakeSpy is under active development and is evolving rapidly; new versions are released every week with additional evasion techniques and capabilities, “ says Cybereason.
The malware sends a fake Postal Service package delivery text message to the victim’s phone . The text message contains a link which the user is encouraged to click on. If the user clicks on the link, it sends them to a malicious web page. The landing page prompts them to download an app that is supposedly the local postal service’s app. The app is actually an Android application package (APK) that is loads FakeSpy malware.
“The fake applications are built using WebView, a popular extension of Android’s View class that lets the developer show a webpage. FakeSpy uses this view to redirect users to the original post office carrier webpage on launch of the application, continuing the deception. This allows the application to appear legitimate, especially given these applications icons and user interface,” says Cybereason
