What are some common techniques used in malware propagation?
Malware propagation techniques often exploit vulnerabilities in operating systems or software applications. Some common techniques include social engineering, where users are tricked into clicking on malicious links or downloading infected files, as well as drive-by downloads, where malware is automatically downloaded without the user's knowledge or consent. Another technique is the use of email attachments or malicious websites that exploit browser vulnerabilities to install malware on the victim's system.
One effective technique for malware propagation is to exploit zero-day vulnerabilities in popular software applications. These vulnerabilities are unknown to the software developer, giving the attacker an advantage. By using a sophisticated exploit kit, the attacker can create malware that can bypass antivirus software and firewalls, allowing it to spread undetected. This technique has been successfully used in several high-profile cyberattacks, such as the Stuxnet worm.
