Report: 2.5 million people fell victim to ransomware last year, up 11% from 2016

istock-645374756.jpgThe number of people who reported encounters with ransomware worldwide in the past year rose from 2.3 million to nearly 2.6 million—an 11.4% increase, according to a report released Monday from Kaspersky Lab.

Mobile ransomware, in particular, continues to be a concern, with 218,625 mobile Trojan-Ransomware installation packages detected in the first quarter of 2017 alone—3.5 times more than the previous quarter, the report found. However, the total number of users targeted by mobile ransomware fell by 4.6% between this year and last year, the report noted.

Kaspersky Lab examined security data from April 2016 to March 2017 and compared it with data gathered the previous year. And these attacks are most common in wealthy countries, with the US experiencing the highest percentage of mobile users attacked with mobile ransomware, followed by Canada, Germany, and the UK.

“Despite a small reprieve, the mobile threat landscape is still arousing anxiety, as criminals target nations with developed financial and payment infrastructures,” according to a press release announcing the report. “Developed markets not only have a higher level of income, but also more advanced and widely used mobile and e-payment systems that can be easily compromised.”

In the US, the rise of mobile attacks came primarily from the Svpeng and Fusob malware families, the report noted. Germany was the country with the highest percentage of mobile users attacked the year before, but the US shifted from fourth to first position this year, with almost 19% of users attacked.

“These geographical changes in the mobile ransomware landscape could be a sign of the trend to spread attacks to rich, unprepared, vulnerable or yet unreached regions,” said Roman Unuchek, security expert at Kaspersky Lab, in a press release. “This obviously means that users, especially in these countries, should be extremely cautious when surfing the web.”
