A recent study was carried out showing enterprise is the new target of malware attacks. Although statistics showed a decline in ransomware attacks on individual consumers, attacks on enterprise showed a clear increase. In fact, the research found that there was a 12% rise in targeted attacks on businesses and a steep 33% increase in mobile ransomware. With the workplace steadily becoming a fluid entity rather than a strict office-based environment, this is particularly concerning.
For those unfamiliar, ransomware trojans encrypt data stored on the device disk, blocking the user from accessing any information. A payment is then demanded and if the extortion is not satisfied, the data is gone for good. Within minutes an entire network can be brought down if the ransomware spreads. This is potentially disastrous for those with no protection or counter measures in place.
Nybble currently protect many large organisations in the UK against this threat and if you are vulnerable, please consider giving us a call. We can assess your business and offer solutions tailored individually to need. But, in the meantime here are 5 ways to protect yourself, at least on a basic level:
If you are running an old version of Windows, you must update your system to Windows 10 or consider new computers. Believe it or not, some businesses still use XP or Vista making them extremely vulnerable to attack. If using Windows 7, ensure you have automatic updates enabled and take note that support will be withdrawn from this operating system soon. The updates are specifically designed to protect against ransomware attacks. Make sure you are using the latest version of your browser and that any plugins are current versions.
Not sure what you have and what you need? Call us, we will guide you through it.
Trojans are often spread by email attachments. The people behind them, the attack groups, are getting very sophisticated and it is easy to be fooled if you don’t know what to look for. Their numbers have grown 25% over 2018. Once the file is unzipped, your files are infected and suddenly all your data is locked down. Make sure staff are made aware of the deception and that to leave unopened, anything they are unsure of or that is unknown. It is important to teach them that sender names can be spoofed, if uncertain a quick telephone call can authenticate before the file is opened. The study showed that 48% of malicious attachments were office files, an upward trend from the 5% of 2017.
Symantec found 1 in 10 URL s posed a risk. Again, it is important that before opening anything, you know who the sender is and what they are sending. Having your company files locked and encrypted can spell disaster for a company and with the highly regulated data protection laws it is just not worth the risk to turn a blind eye. If you think it will never happen to you, you are leaving yourself open to the attack groups. Nybble will advise you on the best anti malware products in the marketplace and monitor your systems remotely for any signs of a breach. In the video below you will hear how the city of Atlanta was held to ransom.
The internet of things, range of devices, varied routers and network set ups all need to be checked and overseen. Even then, infection can occur. Attack group numbers rose 25% in 2018 and many are now attacking via other means than downloadable malware. It is well worth the investment to get your entire system checked for vulnerabilities. Our team are experienced enough to spot where you have weaknesses and can run through a range of solutions.
Probably THE most important piece of advice. Nybble will work with you to ensure you have backed up data to ensure that if the worse happens you will not have to pay an extortionate fee due to blackmail because we can get you back up and running in a matter of hours. We have one of the fastest response times in the industry and treat your business like ours.
