How organisations should react to zero-day threats

Cyber resilience is critical in today’s omni-connected world, we are all being attacked all of the time and if you don’t think you are, you’re simply not looking hard enough. That being the case it is essential that we ensure our knowledge and awareness to the risks and solutions remains both current and informed. Cybercriminals are constantly looking at new ways of exploiting vulnerabilities in an organisation’s defences and one of the more difficult to protect against are Zero-day threats.

 

What is a zero day threat?

A zero-day threat (also known as zero-hour threat or a zero-hour attack) is an attack by a cybercriminal that exploits a potentially serious software security weakness that the vendor or software developer may be unaware of.  The problem is that these are new vulnerabilities which have not occurred before thus don’t match any recognised malware signatures in antivirus solutions which make them very difficult to identify.

 

These attacks often take place through web browsers or via emails containing malicious attachments. The reason for the name zero days is because the developer has zero days to fix the vulnerability (as it has already been exploited) so they need to race to release a patch before hackers exploit the weakness further.

 

What problems do Zero-day threats cause for organisations?

Zero-day threats are particularly dangerous as there is either no known security fix for the vulnerability because it has not been identified previously, or a patch/fix has yet to be released that addresses the vulnerability and developers are still working on a patch.  If successful the malware can steal your data, corrupt your files, install spyware to access sensitive information, access your contacts, compromising your organisation.

 

A well know example of a zero-day attack was a few years ago when Sony Pictures were targeted, hackers managed to access their network and released sensitive information from Sony, including copies of new movies awaiting release, business dealings, top management email communications and business plans.

 

How organisations can react to these vulnerabilities

By definition zero-day attacks are hard to defend against. The main thing an organisation can do is to keep their software up to date, ensure any patches, fixes and updates are applied as soon as they are released. When zero-day threats are announced, check for a solution, most software vendors are quick to release patches. Use enhanced next generation antivirus, solutions like Sophos intercept X include advanced threat detection powered by artificial intelligence and exploit prevention to help protect against hackers exploiting new vulnerabilities.

 

If you think you have been infiltrated by a zero-day attack, take your network offline so it can be investigated and the source found, this then enables appropriate patching of your end-points.

 

Finally have a cyber incident response plan in place (GDPR requires all organisations do this) so if your organisation does suffer from a breach you have a up to date (well tested plan ) that details how the organisation should respond to minimise the impact of a cyber-attack, (this is like the ‘in-case of fire’ instructions found on hotel bedroom doors but dealing with the response steps in case of a cybersecurity incident), wasted time and/or panic in the event of an incident will cost you money!

 

Every business needs to have an adequate CyberSecurity detection, mitigation, and prevention strategy in place. ramsac can help you with all aspects of cyber resilience, if you have questions or need help please contact us and we can organise a consultation.

Changing IT support providers, like changing lawyers, is not a decision any business takes lightly or frequently. The decision is fraught with numerous questions such as whether the new team will understand my business needs, will it cause teething problems, and more importantly, will the reality match the sales pitch! We took that decision to move to Ramsac in January after ten years with another provider and we have not regretted that choice for a moment. Ramsac are simply great! From the get go we have been very well supported from the front line very helpful telephone support team right up to our relationship manager. We feel that the Ramsac team are very much an integral part of us . What however has driven us to write this review is the fabulous support we have received following a cyber attack this week. Something no business wants to happen but is increasingly a sad factor of modern cyber life. The Ramsac cyber support team were superb and really gave us first class support and guidance through what was frankly a horrible experience. Thank you Dan! Denise Herrington

We have worked with Ramsac since 2015. They offer a truly winning formula. We have been delighted by their support at all three levels: our network consultant (Colin) understands our set up and is great when we need to upgrade our infrastructure; we have ready access to our account manager who has been great with supporting our growth; and the helpdesk is always so patient for the day-to-day glitches. Very professional and supportive – thank you team ramsac!

I have known Dan May and Ramsac for 5 or 6 years now. Dan is such a great guy and really helpful with strategic advice and input on all things IT. He's so approachable and doesn't baffle you with IT jargon. If you are looking to outsource your IT or you have a problem you need help with Dan is definitely the one to ask.
