As the new year kicks off, it’s time to take a retrospective look at the past year’s malware landscape. Let’s see what the top malware families, Types, Tactics, Techniques, and Procedures (TTPs) used by attackers in 2023 can tell us about what to expect in 2024.
Data source and methodology
We utilized data from ANY to gain insights into the cybersecurity threats of 2023. ANY.RUN, a malware analysis sandbox. This service analyzes thousands of files and links users submit worldwide, providing valuable information on emerging and persistent threats.
In Q4 2023 alone, ANY.RUN analyzed over 748,000 files and links, identifying over 210 million indicators of compromise (IOCs).
Top Malware Types in 2023
Loaders, the gateway for more sophisticated malware, remained a significant threat throughout the year.
Their primary function is to download and install malicious payloads onto infected systems, often opening the door for further attacks. The increasing accessibility of loaders and the decreasing price tag will likely make them a persistent threat in 2024.
In a notable development, stealers, which focus on stealing financial information and personal data, became the second most prevalent malware type in 2023 despite significantly surging in Q4 with 6,662 detections.
