CompTIA A+ Certification Exam Notes: What are Blended Threats?

Woman working on a computerPeople who take security+ practice tests know that there’s a chance blended threats could be part of their exam. To start, what does it mean?

A blended threat is a malicious software that combines the functionalities of various worms, viruses, and Trojans to start, send, and propagate an attack. As it’s capable of using different techniques and methods, it could spread and cause significant damage to compromised systems.

How Do Blended Threats Work?

Taking a security+ practice test to prepare for the CompTIA A+ Certification exam? To understand how blended threats wreak havoc, CertBlaster and other experts say that you need to know their functionalities. These include:

• Causing Harm – Blended threats are capable of launching a Denial of Service (DoS) attack to a target system, defacing its web servers or planting a Trojan horse that would remain hidden from the user and could be executed remotely.

• Spreading via Different Means – This malicious software is capable of scanning a target system for vulnerabilities. It could then embed malicious code on a server’s HTML files, infect systems through infected websites, and send email messages with an attachment that contains a worm from infected servers.

• Attacking from Various Points Insert malicious code in an affected system’s .EXE files, increase privilege levels for guest accounts, modify the registry, create network shares that are writeable, and inject scripts in HTML files.

• Propagating Automatically and Remotely – Blended threats continuously scours the Internet to look for vulnerable systems it could access.

• Exploiting Vulnerabilities – To access a target system, they exploit known vulnerabilities including weak HTTP input validation, buffer overflows, and weak passwords.

How to Protect Against Blended Threats

For one, you’ll need a robust antivirus solution that uses various layers of response and defense mechanisms. You also need to update your software solutions regularly, use a comprehensive firewall solution, and make certain that users practice safe online behavior and email handling.

Put simply, because there’s really no way to know how blended threats evolve, you need to remain vigilant and protect your system from various possible scenarios.
