Understanding these distinctions is crucial to strengthening your IT security.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>A brief history of computer viruses<\/strong><br\/>Originally, computer viruses were less a tool for fraud and more a field of experimentation for programming students and university researchers. Those days are gone, and today, viruses are often the work of &#8220;black-hat hackers&#8221; &#8211; digital criminals, as opposed to the &#8220;white-hat hackers&#8221; who fight to defend our systems.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Threat typology<\/strong><\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Virus<\/strong>: A malicious program that attaches itself to legitimate software. It requires human intervention to spread, such as opening an infected attachment.<\/li>\n\n\n\n<li><strong>Worm<\/strong>: Spreads automatically between computers, exploiting information transfer systems. A single infected workstation can quickly spread the worm to a multitude of other systems.<\/li>\n\n\n\n<li><strong>Trojan<\/strong>: Inspired by the famous Trojan horse, this type of malware creates a backdoor in your system, allowing attackers to access your personal data or install malware.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><strong>A case in history: the &#8220;I Love You&#8221; worm<\/strong><br\/>In 2004, the &#8220;I Love You&#8221; worm tapped into our desire for affection. It spread via an e-mail entitled &#8220;ILOVEYOU&#8221;, sending itself to all Outlook contacts once opened. It has infected over 10 million Windows systems, causing millions of dollars in damage.<\/p>\n\n<p class=\"wp-block-paragraph\">The best defense against these threats is a combination of vigilance and regular updates of your system and security software.<\/p>\n\n<p class=\"wp-block-paragraph\">At Mofco, we understand the importance of IT security. <\/p>\n\n<p class=\"wp-block-paragraph\">Our managed and cloud-based IT services are designed to ensure a secure, collaborative working environment.
