Security News > 2021 > March > Nearly 40% of new ransomware families use both data encryption and data theft in attacks

Data-stealing ransomware attacks, information harvesting malware, and supply chain attacks are among the critical threats to organizations, according to F-Secure.

One of the most notable trends highlighted is the evolution of ransomware - attacks that extort organizations by preventing them from accessing their data.

2020 saw an explosion of ransomware that also steals data, giving the attackers more leverage over their victims.

Nearly 40% of ransomware families discovered in 2020, as well as several older families, were known to also steal data from victims by the end of last year.

"Organizations with reliable backups and effective restoration procedures are in a strong position to recover from a ransomware attack without having to pay. However, managing a potential data leak is a dramatically different challenge, especially for organizations that possess confidential information," explained Calvin Gan, a Senior Manager with F-Secure's Tactical Defense Unit.

In a retrospective look at the notable supply chain attacks from the last 10 years, the report highlights that over half of them targeted either utility or application software and expresses hope that the last year's SolarWinds hack draws greater attention to the impact these attacks can have.
