Research into the global cyber security threat landscape shows a marked increase in threats to business services, an evolution in ransomware attacks and confirmation that emails are being used to send malicious documents and executables like infostealers and Trojans. Any business connected to the internet has no option but to have cyber security in place.
This is according to findings of cybersecurity company Trellix’ Threat Report: Summer 2022 and input from its Threat Labs (connected to healthcare and access control systems), which together reflect email security trends.
It also details the evolution of Russian cybercrime related to the conflict in Ukraine where new malware or methods have yet to be observed.
Among the key findings:
• 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 US 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 virtualization services with varied success. Leaked chats from the quarter’s 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.
