“81% of large businesses have suffered malicious data breaches”

UK Government 2014 Information Security Breaches Survey

 

We’ve covered the dangers of cyber hacking and how you can protect yourself in a whole series of posts in the Intelligence Centre and we offer protection services for Chambers IT systems.

But what if you don’t even know that you’ve been hacked in the first place?

Unless the hackers are the types that want to brag about their achievements, it is very difficult to know if your system has been hacked, often until it is too late. You may assume, given that you have anti-virus software in place, you are safe. But malicious malware can change its form at will, so while you sit back and let the software the work, hackers could have already found a way around it.

 

Working out whether you’ve been hacked by cybercriminals is like leaving your diary in your bag while you visit the bathroom. When you get back, everything might still be in your bag, but you can’t be certain that no one sneaked a peek.”

Here are 4 sure signs to look out for that your system may have been hacked:

 

1. Fake Antivirus Messages

 

Fake anti-virus messages are one of the most obvious signs that your system has been compromised. They’ll alert you to a breach, and preying on your panic, will direct you to a website to buy their product, enter your credit card and billing information.

Unfortunately, by the time you receive that message, malware will have already used unpatched software to exploit your system – too little too late. Luckily, cases like this are on the decline, but it is the ‘Holy Grail’ for hackers so be alert. If you receive a fake anti-virus message, power down your computer immediately. Don’t click through!

 

2. Redirected Internet Searches

 

Many hackers will redirect you to a website other than the one you want to visit. They make their money by earning clicks for that alternative website. A sure sign of this is websites in your search results that have no relevance to your search term.

 

3. Random Pop-Ups

 

A sure sign that you’ve been hacked is frequent, random pop-ups from websites that you wouldn’t expect. It is quite amazing how easily websites, across the legitimacy spectrum, can bypass your browser’s anti-pop-up mechanisms. Again, a full antivirus scan will eliminate bogus toolbars and malicious pop-up mechanisms.

 

4. Fake Emails From Your Account

 

Are your contacts, friends and business associates receiving emails from your account that you didn’t send? If one or more of your email contacts alerts you to a bogus email, run a full antivirus scan immediately. These days, bogus emails are rarely a sign of a full-out hack, but are an indicator of some kind of malicious malware.

The best way to avoid unexpected and mysterious malware attacks is to carry out regular, schedules antivirus scans and to install a robust security system in Chambers.
