Android ransomware threats on the rise

According to McAfee Labs, there is an increasing number of ransomware attacks on Android.

There are almost 10 million known samples of ransomware. Last year, the number was roughly six million, which is a 59% increase. One of the reasons why these numbers have increased so much is that cybercriminals are targeting Android devices more than they used to.

The Congur ransomware is one of the most noteworthy ransomware families, amounting to 90% of mobile attacks.

One of the fraudulent apps responsible for the increase of infections is Android/SMSreg, a false battery improvement app. Without the knowledge or consent of the user, this app stealthily collects data from the infected mobile device, making it a data security risk.

McAfee’s report predicts that ransomware attacks are likely to become even more widespread in the future. The reason behind this is that ransomware campaigns are very effective, since enough organisations are willing to pay the ransom to restore access to their files.

Other types of malware are also aiding the cybercriminal cause, the ones using sophisticated evasion techniques like the Dridex banking trojan, to name one example.

Vincent Weafer, vice president at McAfee Labs, says there are hundreds, if not thousands, of anti-security techniques used by hackers, and you can obtain many of them on the dark web. He added the evasion techniques used by certain malware can even be used to circumvent machine learning based protection.
