The most common types of malware that Netskope users attempted to download from the web or cloud were Trojans, which are commonly used by attackers to gain an initial foothold and deliver other types of malware, such as infostealers, remote access Trojans, backdoors, and ransomware. Detecting and blocking Trojans can prevent malware infections that would result in other malicious payloads being installed. All other types of malware make up a comparatively small percentage of the total, which is the same as in other regions.
