Business services top target of ransomware attacks | #malware | #ransomware


Business services are the top target of ransomware attacks, according to a new report.

Trellix has released The Threat Report: Summer 2022, analysing cybersecurity trends and attack methods from the first quarter of 2022. 

The report also features research from Trellix Threat Labs into connected healthcare and access control systems. It also includes analysis of email security trends and details the evolution of Russian cybercrime related to the conflict in Ukraine where new malware or methods have yet to be observed. 

Key findings include:

 
Increased Threats to Business Services

Companies providing IT, finance and other types of consulting and contract services were targeted by adversarial actors more often, demonstrating cybercriminals desire to disrupt multiple companies with one attack. Business services accounted for 64% of total U.S. ransomware detections and was the second most targeted sector behind telecom across global ransomware detections, malware detections, and nation-state backed attacks in Q1 2022. 

Ransomware Evolution

Following the January arrests of members of the REvil ransomware gang, payouts to attackers declined. Trellix also observed ransomware groups building lockers targeting virtualisation services with varied success. Leaked chats from the quarters second most active ransomware gang, Conti, which publicly expressed allegiance to the Russian administration, seem to confirm the government is directing cybercriminal enterprises.  

Email Security Trends

Telemetry analysis revealed phishing URLs and malicious document trends in email security. Most malicious emails detected contained a phishing URL used to steal credentials or lure victims to download malware. Trellix also identified emails with malicious documents and executables like infostealers and trojans attached. 

 

“With the merging of our digital and physical worlds, cyberattacks cause more chaos in our daily lives,” says Christiaan Beek, lead scientist and senior principal engineer, Trellix. 

“Adversaries know they are being watched closely; the absence of new tactics observed in the wild during the war in Ukraine tells us tools are being held back. Global threat actors have novel cyber artillery ready to deploy in case of escalation and organisations need to remain vigilant,” he says.

The Threat Report: Summer 2022 leverages proprietary data from Trellix’s network of over one billion sensors, open-source intelligence and Trellix Threat Labs investigations into prevalent threats like ransomware and nation-state activity. Telemetry related to detection of threats is used for the purposes of this report. A detection is when a file, URL, IP-address, suspicious email, network behaviour or other indicator is detected and reported via the Trellix XDR ecosystem.
