The virus that is infamous for attacking through email is called a “email virus” or “email worm”. These types of viruses have the ability to spread rapidly through the internet by disguising themselves as a legitimate attachment or link within an email. When the user opens or clicks on the attachment or link, the virus is then activated and begins to spread itself to other individuals who the infected recipient emails.
One specific email virus that caused widespread damage was the “ILOVEYOU” virus in 2000. This virus was emailed to millions of users worldwide as a love letter with an attached file named “LOVE-LETTER-FOR-YOU.txt.vbs”. Once the recipient clicked on the attachment, the virus would then replicate itself by sending the email to all contacts in the user’s address book, ultimately causing damage to their personal and work computers.
Email viruses have become increasingly sophisticated over time and often require specialized anti-virus software to detect and remove them from infected systems. It is important for individuals to exercise caution when opening emails from unknown or suspicious sources and to always keep their anti-virus software up-to-date to prevent future attacks.
What is one of the most common ways through which virus is spread in email?
One of the most common ways through which viruses are spread in email is through the use of email attachments. Email attachments refer to any file that is sent along with an email message. The attachment may contain a malicious code that, once activated, can infect the recipient’s computer with a virus or other forms of malware.
Hackers and cybercriminals often use email attachments to spread viruses because they are easily accessible and can be disguised as legitimate files. For instance, they could send a Word document or a PDF file that appears to be an invoice or a job offer. Once the recipient opens the attachment, the embedded virus starts to execute its code and makes its way into the user’s computer system.
Another common way viruses are spread through email is through phishing scams. These involve fraudulent emails that try to trick recipients into providing sensitive information such as usernames, passwords, and credit card details. The emails may appear to come from legitimate sources, such as banks, credit card companies or social media platforms, and often contain links that if clicked on can direct users to malicious websites.
These websites may then infect the user’s device with malware or ransomware, which can cause a significant amount of damage to their system.
To protect against viruses spread through email, it is essential to be vigilant and avoid opening attachments or clicking on links in emails from unknown or unverified sources. It is also crucial to have up-to-date antivirus software installed on your devices that can detect and block malware before it can cause any damage.
