Because it is sold as a service, even less technical criminals can purchase and deploy it, increasing the number of active campaigns. Protection and Mitigation Strategies Related search suggestions: Versions 6 and 7 introduced
Perhaps its most dangerous feature from a defender's perspective is its ability to download and execute secondary payloads. This turns an initial XLoader infection into a potential launchpad for ransomware (like LockBit or REvil), banking trojans, or remote access trojans (RATs).
What truly sets XLoader apart is its . While originating on Windows, the malware has expanded its capabilities to target other operating systems, a rarity in the commodity malware space.
