How to prevent Brute Force Cyberattacks
Malware is getting harder and harder to battle. One of the most notorious types is Ransomware.
Ransomware typically encrypts data stored on an infected system and demands a ransom be paid for the release of a decryption key.
This type of cyber-attack is normally hidden in malicious executable files – so you can understand Anti-Virus companies being so caught up in threat protection. The majority of the big hitters in AV have developed new ways of intercepting ransomware.
But there’s one thing they haven’t thought enough about.
What is a Brute force attack?
It’s so simple yet so effective for cyber-criminals.
Essentially, it’s just trial-and-error. They’ll use automated software to generate a large number of guesses as to the value of things such as administrator login credentials.
The benefit for the criminals, is that once they’re in, they don’t need to run any malicous executables. As a result, they can make any changes they want to without being noticed by any sort of anti-virus software. This means they can access sensitive data, or even worse, encrypt it and hold it to ransom.
What can be done to prevent brute force cyberattacks?
Firstly, it’s important to realise that Anti-virus is not the be-all and end-all. It’s useful, but just as a burglar alarm won’t keep your belongings safe if you leave the front door open – other precautions need to be put in place.
And that’s why a more robust approach to keeping your data safe is important:
- FSRM, a script that monitors strange behaviour on your server.
- A strong password policy, strictly enforced via group policy.
- Targeted threat protection for emails containing malware that appear legitimate.
- A security certified gateway for remote sessions.

Why are we still vulnerable to cyberattacks?
Some of the world’s greatest minds have been working for decades to improve cyber security. So why are we are still under threat from cyber attacks?
The answer is quite simple.
Most cyber criminals are reliant on their attacks for income. When they realise that their current income stream has been blocked, they of course will look intensively for ways to improve the effectiveness of their methods. And of course, the more complex our tech becomes, the more vulnerabilities there are to exploit.
Whereas by nature, security updates and patches are reactionary.
This is why it’s very possible that for every 5 examples of malware that are rendered useless, another 10 can easily burst onto the scene.
