Over 500% Increase in Ransomware Attacks Against Businesses

Published on: May 02nd, 2019

Cybercriminals have started focusing their efforts on businesses during Q1 2019, with consumer threat detections decreasing by roughly 24% year over year while businesses have seen a 235% increase in the number of cyber attacks against their computing systems.

For consumers, the number of detections for Trojans and RiskwareTool malware families has kept going down since Q1 2018 and backdoors, spyware, and MachineLearning/Anomalous malware have seen increases of 85%, 95%, and 221% respectively.

On the other hand, when it comes to the malware families detected in corporate environments, Malwarebytes’ “Cybercrime Tactics and Techniques Q1 2019” report shows skyrocketing detection rate all across the board since Q1 2018, while hijackers were the only malware that continued to show up less and less during the last year.

Out of all malware families impacting commercial entities, ransomware has seen huge comeback with increases of 189% since Q4 2018 and a massive 508% uptick since Q1 2018, while on the consumer side ransomware was “knocked out of the top 10 from its previous steady ranking for several years running.”

As detailed by Malwarebytes, this huge increase in corporate ransomware detections happened “thanks in large part to a massive attack by the Troldesh ransomware against US organizations in early Q1.”

This trend is also backed by FBI’s Internet Crime Complaint Center (IC3) annual Internet Crime Reports (2013, 2014, 2015, 2016, 2017, 2018) which show that while ransomware has definitely seen a decrease in the number of incidents since 2016, the total losses have increased despite a decreasing number of complaints.

A detailed overview of the number of yearly ransomware complaint and total losses as reported by the IC3 is available in the table below.

Even though it might not be immediately obvious, this happened because cybercriminals have switched their targets from home users to commercial organizations which can afford to pay larger ransoms to have their computing systems unlocked and files decrypted.

The 2018 edition of IC3’s Internet Crime Report also underlined that not all ransomware victims report the incident, thus leading to an “artificially low ransomware loss rate.”

The Malwarebytes report conclusions are the result of combining statistics and intel collected between January 1 and March 31, 2019.

They rely on data from the company’s “Intelligence, Research, and Data Science teams” with telemetry added to the mix from both the “consumer and business products on the PC, Mac, and mobile devices.”
