Understanding Malware
Malware, also known as malicious software, refers to harmful programs used by cybercriminals to gain unauthorized access to and compromise computers, networks, or servers.

These programs serve as effective tools for attackers to steal sensitive information or disrupt systems.
Malware can be categorized into nine different types, with viruses, worms, and trojans being the most common.
Among them, computer viruses are widespread and can infect and alter important files on a device.
The Proliferation of Worms in the Age of Email Systems
Worms have gained prominence with the rise of email systems and are particularly destructive due to their ability to self-replicate, making them difficult to eliminate.
They can take control of entire computer systems or networks without requiring any action from end-users.
Trojans are often favored by hackers, who strategically plant them on websites or distribute them through malicious emails.
Once a device is infected, trojans can compromise data or spy on the user’s activities.
Defense Against Malicious Attacks
Unlike traditional networks, blockchain systems are highly resistant, if not immune, to malware infections due to their decentralized nature.
However, malicious individuals target users’ devices to steal private keys or credentials for cryptocurrency exchanges, rather than directly attacking the blockchain itself.
Therefore, it is important for cryptocurrency users to install reputable antivirus software and keep it updated.
Additionally, avoiding suspicious websites and avoiding clicking on attachments or links in unfamiliar emails is advisable.
