Trend Micro solutions for Ransomware in Mobile

Trend Micro’s Mobile Protection products contain key technologies to protect against ransomware.

MARS is a cloud-based technology that automatically identifies mobile threats based on app behaviour. Any newly installed application will be scanned by MARS to check if it is a Ransomware. MARS can also perform the following:

  • Crawls and collects a huge number of Android and iOS apps from various markets
  • Identifies existing and brand new mobile malware
  • Identifies apps that may abuse privacy and device resources
  • App repack and vulnerability assessment

WRS and URL Filtering are services that checks the URLs being accessed and blocks those that are unsafe. These services also do the following:

  • URL Categorizations grant URL Category type to each URL, identifying Ransomware
  • Block malicious URL before virus patterns release
  • URL Reputation Scoring grants WRS Score to each URL
  • Stop users from visiting or downloading from malicious URLs
