A worm in cryptocurrency refers to a type of malware designed to spread across networks and devices. Unlike traditional viruses, worms do not require a host file to replicate. They can independently exploit vulnerabilities in software or systems, allowing them to spread automatically.Once a worm gains access to a device, it can perform various malicious activities. This may include stealing private keys, mining cryptocurrencies using the victim’s resources, or even hijacking wallets to transfer funds to the attacker.Worms can cause significant harm by compromising the security of individual users and entire networks. They often spread through phishing emails, malicious downloads, or unsecured internet connections. To protect against such threats, users should adopt good security practices, such as using strong passwords, keeping software updated, and employing robust antivirus solutions. Awareness of the potential risks can also help users avoid falling victim to these harmful programs.
