The cybersecurity vendor's "2023 Global Threat Report," which summarizes CrowdStrike's research on cybercrime (or "e-Crime") from the previous year, was released this week. The report's major sections address ongoing geopolitical disputes, cloud-related attacks, and extortion attacks without the use of software.
One of the major findings from the CrowdStrike research is that the number of malicious actors who conducted data theft and extortion attacks without the use of ransomware increased by 20% in 2022 compared to the previous year. Data extortion is the practice of obtaining confidential information from target companies and then threatening to post the information online if the victim does not provide the ransom demanded by the attacker.
Data extortion has frequently been a part of ransomware operations, with the fear of data exposure intended to provide additional incentive for the victim to pay the demanded ransom. However, as per the CrowdStrike findings, more attackers are now inclining toward data extortion, while abandoning the ransomware element altogether.
Adam Meyers, head of intelligence at CrowdStrike says that “We’re seeing more and more threat actors moving away from ransomware[…]Ransomware is noisy. It attracts attention. It’s detectable. Encryption is complex.”
According to Meyers, the rise in extortion addresses the adaptability of cyber adversaries. He further adds that while ransom payments were down slightly in 2022, both extortion and ransomware-as-a-service (RaaS) have witnessed a significant boost.
CrowdStrike observed and noted the overall waning interest in malware. The firm reported that in 2022, up from 62% in 2021, malware-free activity accounted for 71% of its threat detections.
"This was partly related to adversaries' prolific abuse of valid credentials to facilitate access and persistence in victim environments[…]Another contributing factor was the rate at which new vulnerabilities were disclosed and the speed with which adversaries were able to operationalize exploits," the report said.
While also noting the improved resilience of the RaaS network, CrowdStrike stated that affiliated hackers will continue to be a major concern as they move from one network to another despite the move away from conventional ransomware deployment.
