What is Cryptojacking?

Cryptojacking is the use of your computer by a cybercriminal to mine cryptocurrency without you being aware. Cryptocurrency, such as bitcoin, is very valuable and can be mined using the victims process power, without even noticing. This usually occurs when a website runs hidden cryptocurrency mining scripts in the browser of the victim. Why do they do this?

Cryptocurrency can be worth a lot of money if you have the right resources to mine it. This can be used as payment on certain websites with 1 bitcoin currently worth around £5,700. Criminals therefore use your computer to create tokens of value, which get deposited to the hacker whilst the abilities to mine is used by the hacker on the victim’s system (electricity, computer processing power etc). They use you to make money for themselves.

To get around this, the best method to stay safe is to install a cryptojacking blocker. If you don’t feel like this is necessary, adblocker will also help.

Employee sends damaging computer code to old company – could your company cope?

Employee sends damaging computer code to old company – could your company cope?

This may sound far-fetched but it happened recently in the US. A former IT manager of Smart Online, a company creating mobile Apps, left the company and then sent damaging computer code causing $5,000 worth of damage to computers. The code also deleted much of the company’s intellectual property. He will be sentenced in December this year.

Although justice has been done, it doesn’t help the company – they still have to pay for the damage and retrieve lost data.

How safe are your computers?
Have you changed your passwords recently? What do you do when someone leaves your company? Could they sign in and access or delete company files?

What you don’t want is an ex-employee to still have access to your company data. Imagine the damage that could be inflicted. Website content could be changed, email accounts hacked, social media accessed. The entire reputation and security of your company could be jeopardised in two hours from someone’s bedroom.

Changing passwords – is this enough?
The simple answer is no. It is good practice to have new passwords but, at the very least, you should back-up your data every day and install a ‘disgruntled-employee-proof’ security firewall.

Don’t leave it to chance or be spurred into action by someone leaving. Sort it out now. Call Matrix It Solutions, IT support in Fareham on 01329 888444 or email us on moreinfo@mtxit.com and we can talk you through the options to ensure that this never happens to your company.
