Millions of spam messages are sent every day, and while the majority are harmless advertisements, a malicious file is eventually hidden in one of them. To get the recipient to open the file that downloads the malware, cybercriminals disguise it as a working document, a reasonable offer, a gift card with a well-known company's logo, and so on. Cybercriminals have their preferred file formats. Below are the most common types of files and antivirus used to hide malware. Top cyber security courses online assist in implementing technical strategies, tools, and techniques to secure data and information for your organization.
1. ZIP and RAR Files
Malware is frequently hidden in files by cybercriminals. They used ZIP files, for example. You can set a series of commands while creating a file to unzip the content in the system folder. The files could be copied to the boot folder and run when the computer was restarted. To avoid malware, we recommend enrolling in information security courses and updating the program right away.
2. Microsoft Office Documents
Top cyber security courses online are usually intended for employees who work in offices or people interested in this field. Cybercriminals prefer Microsoft Office files. They're disguised as contracts, invoices, tax notices, and messages from the management team. These files may include embedded macros, which are small programs that run within the file and are used by cybercriminals as scripts to download malware.
3. PDF Documents
4. ISO Disk Images and IMG Disk Images
Although cyber developers have recently focused their attention on IMG and ISO files, they are not used as frequently as previous formats for malware attacks. Disk images are essentially virtual copies of CDs, DVDs, and other types of discs.
What are the best practices for dealing with potentially dangerous attachments?
To protect your team from malware and scams, you don't have to send all messages with attachments or DOCX / PDF documents to the spam folder. Instead, enroll in Top cyber security courses online and keep these simple guidelines in mind:
- Open suspicious emails from unknown senders with caution. You probably don't need a message with a specific theme if you don't know why it ended up in your inbox.
- Allow macros to run on documents received via email only if it is necessary.
- If you have to deal with unknown senders for work, double-check the attached file's address and name. Do not open anything that seems strange to you; instead, consult a cyber developer.
- Take care when clicking on the links in the files. Ignore them if they don't explain why you need access to them. If you want to check, type the website's address into your browser manually.
- Use a security solution or cyber security training courses you can trust to warn you about dangerous files and block and warn you when you try to open a suspicious website.
