What methods can attackers use to deliver malware into a target’s system?

In the context of cyberwar and cyberattacks, attackers employ various methods to deliver malware into a target’s system. These delivery mechanisms often exploit human behavior or technical vulnerabilities to gain unauthorized access.12

Common delivery methods include:

• Email and Phishing: Attackers frequently use phishing emails that impersonate trusted contacts or legitimate organizations. These emails often contain malicious attachments or links that, when opened or clicked, install malware on the user's device.23
• Infected Hardware: Physical media, such as USB flash drives, can be used to deliver malware. In a technique known as baiting, an infected drive might be left in a public place, hoping a target will find and insert it into a computer.12
• Websites and Downloads: Attackers may create fake websites or compromise existing ones to host malicious software. Users may be tricked into downloading malware disguised as legitimate applications or electronic games.2
• Social Engineering: This involves manipulating human users to divulge information or perform actions that compromise security. Beyond phishing, this can include deceptive tactics to lure users into accessing malicious sites.12

It is a fundamental ethical principle that the use of such deceptive and destructive methods to harm individuals, organizations, or critical infrastructure is wrong and violates the security and privacy of others.
