McAfee Labs Threats Report: September 2018

It’s no surprise that in Q2 2018, we continue to see bad actors go where the money is—from coin mining to billing fraud campaigns—and evolve and refine their tactics to defraud unsuspecting victims.

Our latest findings include:

  • Coin miner malware continues to outpace ransomware: Total coin miner malware almost doubled (up 86%) in Q2 with more than 2.5 million new samples, compared with 990,000 for ransomware.
  • New billing fraud campaign on Google Play: The McAfee Mobile Research team found 15 new apps—including a ringtone of the hit song “Despacito”—that contained a fake installer app aimed at subscribing users to premium-rate services without their knowledge.
  • JavaScript malware surges in Q2: After decreasing significantly during the last three quarters, JavaScript malware increased by 204% in Q2, with more than 7 million new samples.
