In cybersecurity, 'riders' refer to malicious code or software components that are covertly attached to legitimate files or applications. These riders are designed to execute alongside the host program, often without the user's knowledge, enabling attackers to perform unauthorized actions such as stealing data, installing additional malware, or gaining remote access. Riders are commonly distributed through software bundles, email attachments, or compromised downloads. Because riders piggyback on trusted files, they can evade basic security checks, making detection and removal challenging. Effective cybersecurity practices, such as using updated antivirus software and avoiding suspicious downloads, are essential to defend against rider-based threats.
