Security News > 2022 > August > Cybersecurity agencies reveal last year’s top malware strains
The U.S. Cybersecurity and Infrastructure Security Agency released a list of the topmost detected malware strains last year in a joint advisory with the Australian Cyber Security Centre.
"Most of the top malware strains have been in use for more than five years with their respective code bases evolving into multiple variations," the cybersecurity agencies said.
"The most prolific malware users of the top malware strains are cyber criminals, who use malware to deliver ransomware or facilitate theft of personal and financial information."
"Developers of these top 2021 malware strains continue to support, improve, and distribute their malware over several years. Malware developers benefit from lucrative cyber operations with low risk of negative consequences," the agencies added.
"Many malware developers often operate from locations with few legal prohibitions against malware development and deployment."
The joint advisory includes Snort signatures for all malware in the top to detect payloads by monitoring network traffic and a list of mitigation measures.
