Editor’s brief: According to the research arm of cybersecurity vendor Check Point Software, the takedown of the Emotet botnet by international police teams in January 2021, threat actors have gone back to using Trickbot trojan as a tool for attempting to infiltrate and exploit networks and devices. The vendor’s release is below.
February 2021’s Most Wanted Malware: Trickbot Takes Over Following Emotet Shutdown
Check Point Research reports that following the international police operation that took control of Emotet in January, cybercriminals have turned to Trickbot to maintain their malicious activities
SINGAPORE, @mcgallen #microwireinfo, March 12, 2021 – Check Point Research, the Threat Intelligence arm of Check Point® Software Technologies Ltd. (NASDAQ: CHKP), a leading provider of cyber security solutions globally, has published its latest Global Threat Index for February 2021. Researchers reported that the Trickbot trojan has topped the Index for the first time, rising from third position in January.
Trickbot was the 4th most prevalent malware globally during 2020, impacting 8% of organisations. It played a key role in one of the highest-profile and expensive cyberattacks of 2020, which hit Universal Health Services (UHS), a leading healthcare provider in the U.S. UHS was hit by Ryuk ransomware, and stated the attack cost it US$67 million in lost revenues and costs. Trickbot was used by the attackers to detect and harvest data from UHS’ systems, and then to deliver the ransomware payload.
“Criminals will continue using the existing threats and tools they have available, and Trickbot is popular because of its versatility and its track record of success in previous attacks,” said Maya Horowitz, Director, Threat Intelligence & Research, Products at Check Point. “As we suspected, even when a major threat is removed, there are many others that continue to pose a high risk on networks worldwide, so organisations must ensure they have robust security systems in place to prevent their networks being compromised and minimise risks. Comprehensive training for all employees is crucial, so they are equipped with the skills needed to identify the types of malicious emails which spread Trickbot and other malware.”
Check Point Research also warns that “Web Server Exposed Git Repository Information Disclosure” is the most common exploited vulnerability, impacting 48% of organisations globally, followed by “HTTP Headers Remote Code Execution (CVE-2020-13756)” which impact 46% of organisations worldwide. “MVPower DVR Remote Code Execution” is third place in the top exploited vulnerabilities list, with a global impact of 45%.
