Ransomware is malware that takes files on a PC or network storage, encrypts them and then by force puts you in ransom for money to unlock the files. It is be becoming widespread and can be damaging to businesses. In order to optimise the security of your business or personal data, AMJ UK has put together a few tips to keep in mind when using emails, the internet or any form of IT Communication tool.
- Backup regularly and keep a recent backup copy off-site
This is a good practice in general where files can be lost or accidentally deleted. Always have a regular backup of your files and encrypt them to prevent access from unauthorised persons. For backup options and solutions, please refer to our article on cloud backup solutions.
- Don’t enable macros in document attachments received via email
Make sure you turn off the auto execution of macros in Microsoft. A lot of infections are used to turn macros back on and executing infections.
- Be cautious about unsolicited attachments
Cyber criminals rely on the dilemma for emails you can’t tell if the file is the one you want until you open it. Google the email address to check otherwise, if in doubt leave it out.
- Don’t give yourself more login power than you need
Staying logged on as an administrator any more than necessary can cause unwanted problems. Avoid browsing or opening documents or other regular work activities while you have administrator rights.
- Stay up-to-date with new software and security features in your business
Microsoft Office 2016 now includes a block feature on macros from running in Office files from the internet control. This helps protect against external malicious content without stopping you using macros internally.
