Darktrace, a global leader in cyber security AI, today reported that its security researchers discovered a 30% increase in the average number of attempted ransomware attacks globally over the holiday season in every consecutive year from 2018 to 2020 compared to the monthly average.
The researchers also observed a 70% average increase in attempted ransomware attacks in November and December compared to January and February. Following a record number of ransomware attacks this year, the company expects the spike to be higher over the 2021 holiday period.
During the nascent 2021 holiday season, Darktrace’s AI detected and autonomously stopped an in-progress, early-stage ransomware attack on a U.S. city before any data exfiltration or encryption could occur. The city’s security team had the foresight to deploy an AI solution to combat multi-stage ransomware attacks, enabling them to stop the attackers at the earliest stage.
Ransomware is often falsely considered an encryption problem. This misconception masks and undermines attackers’ determination and creativity to initially break into and then move around within an organization’s digital environment first to discover, then steal and encrypt data. The break-in is often through email, but that quickly evolves to targeting servers where the data lives. Therefore, a combination of email and network security is crucial to stop these attacks.
Powered by Self-Learning AI, Darktrace technology develops an understanding of normal business operations for each organization. It autonomously interrupts in-progress attacks at every stage from the initial entry with sophisticated spearphishing emails to brute-forced remote desktop protocol (RDP), command-and-control, and lateral movement, all without business disruption.
