Study reveals no platform is immune from ransomware

Monday 13 November 2017 09:44 CET | News

While ransomware predominately attacked Windows systems in the last six months, Android, Linux and MacOS platforms were not immune, according to SophosLabs 2018 Malware Forecast.

The report also tracks ransomware growth patterns, indicating that WannaCry, unleashed in May 2017, was the number one ransomware intercepted from customer computers, dethroning longtime ransomware leader Cerber, which first appeared in early 2016. WannaCry accounted for 45.3% of all ransomware tracked through SophosLabs with Cerber accounting for 44.2%.

The SophosLabs 2018 Malware Forecast reports on the acute rise and fall of NotPetya, ransomware that wreaked havoc in June 2017. NotPetya was initially distributed through an Ukranian accounting software package, limiting its geographic impact. It was able to spread via the EternalBlue exploit, just like WannaCry, but because WannaCry had already infected most exposed machines there were few left unpatched and vulnerable.

Android ransomware is also attracting cyber criminals. According to SophosLabs analysis, the number of attacks on Sophos customers using Android devices increased almost every month in 2017.

The SophosLabs report further indicates two types of Android attack methods emerged: locking the phone without encrypting data, and locking the phone while encrypting the data. Most ransomware on Android doesn’t encrypt user data, but the sheer act of locking a screen in exchange for money is enough to cause people grief, especially considering how many times in a single day information is accessed on a personal device.

The SophosLabs 2018 Malware Forecast is based on data collected from Sophos customer computers worldwide during April 1 to Oct. 3, 2017.
