The dangers of opening email attachments

Most email users have been warned time and time again about the dangers of opening email attachments from unknown sources. However, many people continue to do so, putting themselves and their computers at risk in the process. Here are just a few of the dangers of opening email attachments from unknown sources:

1. You could be opening yourself up to malware.

One of the most common ways that malware is spread is through email attachments. If you open an attachment from an unknown source, you could be unknowingly downloading and installing malware onto your computer. This malware can then be used to wreak all sorts of havoc, from stealing your personal information to holding your files hostage until you pay a ransom.

2. The attachment could be a virus.

In addition to malware, email attachments can also contain viruses. These are programs that are specifically designed to harm your computer, and can do anything from deleting your files to corrupting your hard drive. Some viruses are even designed to spread themselves by emailing themselves to everyone in your address book.

3. You could be giving the sender access to your computer.

When you open an attachment, you’re not just opening the file itself, you’re also giving the sender access to your computer. This is because many types of attachments can actually be used to execute commands on your computer, meaning the sender could theoretically do anything they want with your machine. This is a serious security risk that should not be taken lightly.

4. The attachment could be a phishing attempt.

Phishing is a type of online scam where criminals try to trick you into giving them personal information, such as your login credentials or credit card number. One of the most common ways that phishers try to trick you is by sending you an email with an attachment that appears to be harmless, but is actually a malicious program that will steal your information once you open it.

5. The attachment could contain harmful macros.

Certain types of attachments, such as those in Microsoft Office documents, can contain macros. These are small programs that can automate tasks, but can also be used to execute malicious code. If you open an attachment that contains harmful macros, you could be allowing the attacker to run whatever code they want on your machine.

As you can see, there are many dangers associated with opening email attachments from unknown sources. The best way to protect yourself is to simply exercise caution when handling email attachments. If you’re not sure whether or not an attachment is safe, err on the side of caution and don’t open it..Published here

How do computer viruses work?

A computer virus is a malicious code that propagates by inserting itself into legitimate programs or files and then replicating itself. The term “virus” is derived from the Latin “virus” which means “poison”.

A virus can only spread if there is a vulnerable program or file to infect. When a virus infects a program or file, it modifies the code to include a copy of itself. When the infected program or file is executed, the virus code is executed as well, causing the virus to spread.

Most viruses are designed to harm the infected computer by deleting files, corrupting data, or causing the machine to malfunction. However, some viruses are designed simply to replicate themselves and do not cause any direct damage.

Viruses can be spread in a number of ways, including email attachments, file sharing, and infected websites. It is important to note that a virus cannot spread without a human action, such as clicking on an email attachment or downloading a file from an infected site.

There are a number of antivirus programs available that can detect and remove viruses from your computer. It is important to keep your antivirus software up to date in order to protect your machine from the latest threats.
