Common Delivery Methods of Malware 01 02 03 Email Attachments Malicious Links Infected Software Downloads Malware is frequently delivered through malicious email attachments, where unsuspecting users are tricked into opening files that execute harmful code upon download. Cybercriminals often use deceptive links in emails or on websites, leading users to compromised sites that automatically download malware onto their devices without consent. Downloading software from untrusted sources can introduce malware, as these programs may be bundled with harmful payloads designed to exploit system vulnerabilities. digitdefence.com
- 4. Impact of Malware on Devices Device Performance Degradation Data Loss and Corruption Unauthorized Access and Control Malware can significantly slow down device performance by consuming system resources, leading to increased load times and reduced efficiency in executing tasks. Infections can result in the loss or corruption of critical data, as malware may delete files or encrypt them, making them inaccessible without a decryption key. Certain malware types enable attackers to gain unauthorized access to devices, allowing them to control systems remotely, steal sensitive information, or launch further attacks. digitdefence.com
