Technology advances at a rapid pace, and this means you need to build scalability into your IT infrastructure to maintain future productivity.

Businesses need to future proof their IT infrastructure to ensure long-term success and sustainability. After all, technology is constantly evolving, and failing to adapt can result in outdated systems which hinder growth, productivity, and competitiveness. But if you adopt a culture of future proofing, you can minimize this risk by using new technology to enhance scalability and maximize your productivity. Implementing scalability, however, is easier said than done. And that’s why we’ve decided to give you a head start with some suggestions.

The Best Future Proofing Methods for Success

If you want to make sure that your IT infrastructure remains relevant and keeps one eye on the future, make sure you adopt these best practices for future proofing:

Use the cloud: one of the simplest ways to future proof your IT operations is by adopting cloud-based solutions. With a wide range of providers and plans available, you can use cloud-based platforms to take care of your storage, software, and infrastructure. Best of all, these services can easily be upgraded to cope with future demand, this makes cloud computing the epitome of scalability and reduces the risk of your in-house hardware becoming obsolete.

Invest for the future: while it may make financial sense, in the short term, investing in low quality IT hardware will only ever provide a short term solution. You see, given how fast technology evolves, if you buy IT equipment at the cheaper end of the market, its performance levels will soon be superseded by newer technology. Therefore, while remaining financially sensible, make sure you invest in the best technology you can afford to increase its lifespan and suitability for your needs.
Virtualization: this creates virtual versions of resources and allows your business to optimize your equipment and reduce costs. Virtualization optimizes your resources by consolidating multiple virtual machines onto a single server, this approach will reduce costs and enhance efficiency. It also helps to future proof your IT infrastructure as it allows you to scale resources up or down quickly based on demand. So, not only is your system flexible and scalable, but it also provides a strong foundation for your IT infrastructure going forwards.
Watch technology: if you want to future proof your businesses IT operations, then it’s crucial that you keep an eye on what’s happening in the world of technology. This will ensure that you are aware of innovative opportunities for growth within your business. More importantly, it will give you time to plan and implement these innovations early on compared to your competitors. This will give you not only a competitive edge, but it will also allow you to anticipate changes in customer behavior.
Strengthen your security: cyber criminals are constantly updating their methods of attack, so you need to keep pace with them to secure your IT infrastructure. Accordingly, always make sure that your antivirus software is up to date and that your employees are educated about upcoming, as well as contemporary, threats. These simple steps will help facilitate the future security of your IT systems.

Aug 2023

Microsoft Teams has experienced a surge in popularity among businesses since the pandemic, and this makes it a highly prized target for hackers.

Businesses find Microsoft Teams a powerful tool as it allows employees to work remotely, communicate and be productive. And it’s all through one app. This is why it’s a fantastic business solution and used by 280 million people. Naturally, the size of this audience is going to turn a threat actor’s head. Where there are high numbers of users, there’s an opportunity for malware to be successful. And that’s why the discovery of a vulnerability in Teams has caused so much concern.

The Vulnerability Lying Within Microsoft Teams

One of the main uses of Teams is as a communication tool, a nd this means that the potential for spreading malware via file transfers and linked hard drives is high. But this newly discovered vulnerability is very different. Therefore, it’s important you understand the threat it poses.

Now, Microsoft Teams allows you to communicate with a wide range of people within your organization. It also allows you to communicate with external parties e.g. subcontractors, clients and facility management teams. Usually, these external users are unable to transmit files to other organizations through Teams. And this is a good thing, as it lowers the risk of malware being sent between businesses.

However, the security protocols which are in place to stop unauthorized file sending can, it turns out, be compromised. Once this vulnerability is exploited, a threat actor can start sending malware direct to the Teams inbox of staff within that business. Often, the threat actors are increasing the chances of their attack being successful by setting up similar email addresses to that of their target. All it takes is for one employee to open the malware and it can start to spread.

While the incoming message will still be tagged as “External”, the busy nature of many employees’ days means that it’s likely this message will be ignored. Also, this method of attack is relatively new. Users are well drilled in the telltale signs of a phishing email, but a Teams instant message is very different. Accordingly, the risk of falling victim to this attack is concerning.

Staying Safe on Microsoft Teams

Curiously, Microsoft has advised that this vulnerability doesn’t, at present, warrant fixing. No doubt, at some point, it will be patched, but for now you should remain cautious. To help strengthen your defenses, make sure you practice the following:

Always update: there’s never an excuse for not carrying out software updates once they are available. It’s the quickest and simplest way to plug weak points in your cyber defenses, so, if they are not already in place, setting up automatic updates should be your priority.

Warn your staff: make sure that your staff are aware of this new threat to minimize the risk of your business falling victim. You can achieve this by sending out email updates to your staff and also updating your IT induction process to cover this new form of attack.

Reduce your availability: it’s possible to limit your communication through Teams to specific domains only. Again, this reduces your risk by ensuring that your staff can only communicate with trusted sources and not threat actors operating from similar, yet malicious domains.

Every business wants their IT infrastructure to be secure, so it’s crucial that you understand all your options. And two of the best are an SOC and an NOC.

A Security Operations Center (SOC) and a Network Operations Center (NOC) are exciting options for your defenses, but not everyone knows what they are. The good news is that both of these options, which can be based in-house or outsourced to external contractors, are here to protect your IT operations. And they both do this with a high level of sophistication, which ensures that cybersecurity threats are quickly identified and nullified.

How Does an SOC Protect Your IT Infrastructure?

Integrating an SOC into your cybersecurity strategies is one of the quickest ways to enhance your defenses. In short, an SOC is a dedicated team of professionals who can provide 24/7 monitoring of your IT systems. Their main duties include:

Maintenance: one of the surest ways to keep any system operating effectively is through routine and preventative maintenance. And this is a duty which an SOC will take in its stride. From initiating and installing updates through to updating firewalls and managing backup protocols, a dedicated SOC will ensure that none of these vital tasks are missed.
Creating response plans: in the case of a security incident, your organization needs to have a solid response plan ready to go. This could involve restoring data from backups, partitioning your networks, or even shutting your entire IT infrastructure down. Regardless of the strategy, you need to make sure that the perfect response plan has been formulated. And, thanks to the experience of those employed in an SOC, you can rest assured that your response minimizes disruption.
Monitoring: security incidents can strike your organization at any time of day, so it’s important that you have round-the-clock monitoring to flag up any attacks. An SOC can take care of this by not only monitoring network activity, but also analyzing it to provide a strong determination as to the threat level posed. This allows the SOC team to quickly identify potential threats and react accordingly.

Why Does Your Organization Need an NOC?

IT networks are complex, highly complex. This means that monitoring them effectively is difficult, but crucial when it comes to securing them. It’s difficult for your standard IT team to dedicate themselves to this task, so this is why the emergence of NOCs is so exciting for organizations. With an NOC supporting your IT infrastructure, you can expect 24/7 coverage in the following areas:

Network monitoring: an NOC can provide your organization with constant network monitoring and surveillance. This monitoring will cover all of the most common elements found in a network such as servers, routers, and switches. It’s an approach which is not only comprehensive, but also allows the NOC team to minimize any disruptions to your network.
Enhanced security: the main aim of a threat actor is to bypass the security of your network, and it’s very easy for them to sneak in when a vulnerability is in place. However, the presence of an NOC team means that not only will updates and patches be installed quickly, but their constant monitoring of your network will allow them to identify any unauthorized access.
Performance monitoring: given the level of competition within business in the 21^st century, your organization’s network needs to perform at a high level. Monitoring the complexities of an IT network, though, is a tough ask. But the experience of an NOC team means they can easily analyze your network performance, and then suggest plans for improving and maximizing its output.

Jul 2022

A new piece of malware has been found to be targeting Microsoft Exchange servers operated by both military and government organizations all over the world.

Discovered by security giants Kaspersky, who also gave the malware its name, SessionManager appears to have been at large since March 2021, but its existence has only just been confirmed. It’s believed that SessionManager was created by Gelsemium, a relatively new hacking group who have already conducted a number of serious cyber-attacks.

Naturally, you would expect military and government organizations to have some of the strongest cybersecurity measures in place. And they do. However, there’s not a single IT infrastructure which can be described as 100% secure. And, as SessionManager has proved, where there are vulnerabilities, there’s a way in.

How Does SessionManager Operate?

At the start of 2021, Kaspersky revealed details of ProxyLogon, a series of vulnerabilities discovered in Microsoft Exchange. As a result of these vulnerabilities, threat actors were presented with an opportunity to install malicious modules into web server software for Microsoft’s Internet Information Services (IIS). And this is exactly how the SessionManager module came to be embedded within numerous organization’s servers.

Once installed, the threat actors were able to use SessionManager to carry out the following tasks:

Carry out remote command execution on affected devices
Gain quick and easy access to email accounts within the organization
Install further malware to maximize the way in which servers were compromised
Using infected servers to manipulate traffic moving across the network

As SessionManager has managed to operate without detection for over a year, it has been able to harvest signification amounts of sensitive data and take control of high-level networks. Even after SessionManager’s discovery, security experts have been slow to move, with Kaspersky commenting that a popular file scanning service was still failing to detect SessionManager. Accordingly, SessionManager remains active in the digital wild and maintains its threat.

What If You’re Infected with SessionManager?

Even if you do discover that your network has been infected by the SessionManager module, deleting it is not enough to fully rid yourself of it. Instead, you will need to go through the following:

The most important step to take first is to disable your IIS environment
Use the IIS manager to identify all references to the SessionManager module and ensure that these are fully removed
Update your IIS server to eliminate any known vulnerabilities and leave it fully patched
Restart your IIS environment and run a final check for any traces of SessionManager

If, of course, you want to prevent vulnerability threats such as SessionManager being enabled in the first place, then you need a conscientious approach to updates. The sooner you can install a firmware upgrade or a security patch, the sooner you can plug security holes in your IT infrastructure.

Sure, we live in a fast-paced world and it’s easy to forget minor tasks such as installing upgrades, but with automate installs a viable option, there’s not really an excuse. Therefore, keep your organization’s network safe by automating updates and enjoying the peace of mind this brings.

ZuoRAT Malware: A New Threat to Routers

Jul 2022

Small businesses rely on routers to keep themselves and their customers connected. But this relationship could now be at risk due to the ZuoRAT malware.

For online communication to work, data needs to move from one computer network to another. And this is exactly what a router does. By directing traffic across the internet, a router can be used to deliver emails, transfer files and stream videos between PCs. Without a router, you simply won’t be able to send or receive data. So, as you can see, they’re an essential part of any small organization’s IT network. Unfortunately, this is the type of IT necessity which hackers love to interfere with. And the ZuoRAT malware does this with a disturbingly sophisticated ease.

The Lowdown on ZuoRAT

ZuoRAT is a strain of malware which takes advantage of vulnerabilities in routers produced by the popular manufacturers Cisco, Netgear, DrayTek and Asus. By exploiting these vulnerabilities, ZuoRAT can access local area networks (LAN) and harvest network traffic from the infected devices. This information is then transmitted to a remote ‘command and control’ server, so, for example, any login credentials which pass through your router will be transmitted to the hacker’s server.

However, ZuoRAT doesn’t stop at hijacking LAN traffic; it downloads additional malware in the form of two further remote access trojans (RAT). These RATs are used to infect devices connected to the network and facilitate the spread of the infection even further. This could, in theory, lead to the infected network being converted into a botnet or, worse still, allow the spread of ransomware across the network.

Although ZuoRAT is relatively new, it has been active in the digital wild since April 2020, and this has given it plenty of time to exploit a wide range of routers. It’s also important to point out that ZuoRAT made its debut at the start of the Covid-19 pandemic. Given that it targets SOHO (small office/home office) routers, ZuoRAT was perfectly placed to attack employees who were working at home with limited IT support. As a result, it has been presented with an opportunity to steal sensitive data with relative ease.

Protecting Your Network from ZuoRAT

Due to the way in which it was designed – a custom build through the complex MIPS architecture – ZuoRAT is not detected by conventional anti-malware software. Therefore, if you own a router made by the affected manufacturers, it’s crucial that you make sure the associated software is up-to-date and fully patched. As ever, monitoring network traffic is a smart move as this will allow you to flag up any suspicious activity.

Final Thoughts

Threats such as ZuoRAT present numerous problems to organizations, most notably due to their multi-pronged attack strategy and stealthy nature. However, it also demonstrates a perfect example of why you need to manage updates relating to your IT equipment. Implementing an upgrade strategy which takes advantage of automated processes has never been more important.
