Every business relies on digital documents, but the threat of data breaches and cyberattacks mean these documents must be correctly secured.

There are many types of documents a business uses daily such as Word, Excel, PDF, and digital images. All of these can contain sensitive information, and it’s no surprise threat actors want to get their hands on them. Not only can a threat actor use these to compromise other accounts, but they can cause real financial damage with them. Accordingly, it makes sense to secure your organization’s digital documents to keep them safe.

Securing Your Digital Documents

Your business may contain numerous files in different locations, but the good news is that securing all of them is straightforward. Just make sure you follow these best practices:

Password Protection: the simplest way to secure your digital documents is by implementing password protection. A common security measure for decades, passwords put a major barrier in the way of unauthorized access. Not all files can be password protected, but common files such as Microsoft 365 documents and Adobe PDF documents can.
Use Strong Passwords: central to good password protection is strong passwords. Never use passwords which are easy to guess e.g. using “password” or “admin”. Instead, always use passwords which combine upper and lower case characters with numbers and symbols. It’s also recommended that passwords are longer than 8 characters and different passwords should be used for different documents.

Restrict Access: it’s important to remember not every employee needs access to every single file within your organization. Your marketing team, for example, doesn’t need access to your finance team’s documents and vice-versa. Accordingly, you need to restrict access to only those who need it. The best way to achieve this is by setting up ‘restricted’ drives for each team to store their department-specific documents.
Use Windows Encryption: compromised devices present a goldmine of data for threat actors, but it’s possible to avoid this disaster by encrypting your devices. Yes, if you’re running Windows 10/11 Pro or Enterprise versions, it’s possible to encrypt data and provide access only to those with authorization. This is easy to put in place and, if Windows encryption is not available on the device, you may still be able to use BitLocker encryption to encrypt it.
Always Create Backups: in the event of a ransomware attack, your organization could find all of its documents encrypted and inaccessible. This is why creating backups is the surest way to enhance the security of your digital documents. The preferred method for executing this is with the 3-2-1 backup method, as this provides you with multiple copies in different locations. Complete loss of your data is minimized and there’s no need to pay any ransom fees.

Final Thoughts

All it takes is for a single file to be compromised by threat actors to cause major damage, so it’s crucial that you prioritize securing your digital documents. Putting the suggestions above into practice is relatively easy, and it ensures your data remains safe. So, don’t delay, secure your digital documents today and benefit from the peace of mind it provides.

Healthcare organizations across the United States and Europe have recently found themselves targeted by Lazarus, the North Korean hacking group.

Lazarus, who are believed to have ties to the North Korean government, are well known in the world of cybersecurity. In 2022, Lazarus were rumored to have stolen a total of $1.7 billion worth of cryptocurrency across the year. So, yes, Lazarus is a force to be reckoned with. As their latest attack targets organizations rich in sensitive data, it’s important to understand their methods and determine the lessons that can be learned.

What Is Lazarus’ Latest Campaign?

At the heart of this new attack by Lazarus is the ManageEngine ServiceDesk. This management suite is used to help organizations manage their entire IT infrastructure. From networks and servers through to mobile devices and applications, ManageEngine helps make life easier for IT teams. It’s a highly popular management suite, with numerous Fortune 100 businesses implementing it. For healthcare organizations, it’s a crucial service which allows them to stay productive and support their IT systems.

However, as with all, applications, ManageEngine is not 100% secure. The CVE-2022-47966 vulnerability, which was discovered in January 2023, was first exploited by threat actors in February of the same year. This vulnerability allowed the deployment of QuiteRAT, a new and complex brand of malware. QuiteRAT let the threat actors steal data relating to the compromised device and, cleverly, allowed QuiteRAT to “sleep” in order to appear dormant and stay off the radars of security professionals.

Another part of the attack also involves a new strain of malware dubbed CollectionRAT, which has the ability to perform typical remote access trojan tasks such as executing commands on a compromised system. As with previous campaigns, this latest strike utilizes many of the trademark Lazarus tactics and innovations. For example, by using open-source tools to create CollectionRAT, the threat actors are able to launch their attacks more quickly and without raising the alarm immediately.

How Do You Protect Your Organization from Lazarus?

Naturally, the most obvious way to protect your IT infrastructure from Lazarus is to be prompt with installing software patches. Lazarus appears to have infiltrated these healthcare organizations due to a known vulnerability, so patching any holes within your IT systems is essential. Luckily, many updates, such as Windows, can be set to automatic and ensures that your applications are as secure as they can be.

Hacking groups, however, don’t rely solely on vulnerabilities to launch their attacks. In fact, they will deploy almost every technique you can think of to launch an attack. The best practices to stay safe from these are:

Create backups: when confronted with any form of malware, there’s a good chance that your business data will be at risk or being compromised or even permanently erased. Therefore, it’s important that your organization creates regular backups to preserve your data and productivity. One of the most comprehensive methods you should use is the 3-2-1 backup method.
Educate your staff on phishing: staff awareness of phishing is crucial due to the rising risk of phishing and social engineering attacks. Recognizing the telltale signs of a phishing email prevents the chances of data breaches and compromised credentials. This will result in a securer IT landscape for your organization and protect your networks and data.

Oct 2023

With cyber-attacks showing no signs of slowing up, it’s more important than ever before to make sure your organization’s IT systems are protected.

Luckily, this doesn’t necessarily involve huge amounts of investment. In fact, some of the most effective ways to protect your IT infrastructure are the simplest. But not ever business realizes this, and this is why so many find themselves falling victim to cybercriminals. Therefore, it’s crucial that you start implementing the best solutions for protecting your organization.

How Do You Keep the Cybercriminals at Bay?

To help you get started with securing your defenses, we’ve put together 5 easy ways to improve your organization’s cybersecurity:

Two-factor authentication: passwords are an amazing method of protection, and this is why they have been used as a security measure for decades. However, a breached password is of little use when it comes to securing your IT systems. Therefore, implementing two-factor authentication should be a major priority. This extra layer of security involves a user receiving a unique code – via registered text or email – to confirm their identity after entering their login credentials. This means that, even if a password is stolen, there is a further security hurdle to overcome.

Training as a team: training sessions are essential when it comes to educating your staff on the dangers of malware and threat actors. However, one-to-one IT induction processes aren’t enough. You also need to develop programs which train your team as a whole. Studies have shown that group learning is more effective and this is exactly what you need when building your IT defenses.

Secure your networks with a VPN: one of the best ways to protect your organization’s data and internet connections is by using a virtual private network (VPN). A VPN establishes secure connections between remote employees and the organization’s network, maximizing data privacy and preventing data breaches. It does this by encrypting data transmissions, shielding sensitive information from hackers, and preventing unauthorized access. Combined with tunneling protocols and authentication mechanisms, a VPN will help you create a secure digital barrier.

Create backups: many cyberattacks, particularly ransomware campaigns, focus on stealing and restricting access to data. This is why backups should form a major part of your IT defenses. By creating multiple backups – see our guide to the 3-2-1 backup method – you are essentially creating a safety net for your business in the event of a data breach. While it may not mitigate every negative impact of a data breach – such as customer data being leaked – it will minimize the risks of data loss.

Secure your Wi-Fi network: there’s absolutely no need for your Wi-Fi network to be publicly visible. By advertising the presence of your Wi-Fi network, you are inviting threat actors to test your defenses. Therefore, you need to not only secure and encrypt your Wi-Fi network, but also hide it from public view. This can be achieved by instructing your router to never broadcast its network name, also known as the Service Set Identifier (SSID).

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.

Apr 2023

The world of malware evolves rapidly, sometimes from one day to another, but one of the most recent surges in popularity has been found in wiper malware.

You may not be familiar with wiper malware, but it’s a form of attack which has been steadily generating headlines over the last year. And the most recent data from FortiGuard Labs shows there was a 53% in wiper malware activity between Q3 to Q4 in 2022. Any increase in malware activity should be a concern, but anything which is over 50% represents a significant threat. This threat becomes magnified further when you consider the impact of wiper malware. Accordingly, there’s never been a more pressing time to learn about wiper malware.

What is Wiper Malware?

Wiper malware gets its name from its purpose of completely erasing all data from hard drives. Although it may seem similar to ransomware, wiper malware typically demands a fee in exchange for data recovery, but in reality, there is no chance of retrieving the data from the attackers. This type of cyber-attack is highly destructive and can cause harm not only to security but also to IT infrastructures.

Why is Wiper Malware Surging?

The initial surge in wiper malware, first observed in the first half of 2022, was attributed to the war in Ukraine. Most of this activity was the result of advanced persistent threat (APT) hacking groups from Russia supporting their governments campaign in Ukraine. And, as this conflict is still ongoing, the wiper malware threat has remained.

However, Fortinet has observed that the range of threat actors implementing wiper malware has now widened. So, as well as APT groups, wiper malware is also being unleashed by threat actors seeking financial gain and hacktivists looking to push political agendas. The research conducted by Fortinet also indicates that this surge currently shows no signs of slowing down, so it’s a threat which appears here to stay.

How Do You Combat Wiper Malware?

You may not feel as though your organization is a typical target for wiper malware, but this could quickly change due to the increased adoption of wiper malware. Therefore, you need to make sure you’re prepared for this type of attack:

Act promptly: In the event of a wiper malware attack, it’s crucial to begin segmenting your network to minimize the malware’s spread. This approach may not protect all your data, but it can help salvage significant portions. Additionally, keep a constant eye on your network for any unusual activities to prompt you into launching contingency efforts in such situations.

Ensure Careful Backups: one of the best ways to reduce the impact of a wiper malware attack is by taking proper backup measures. As malware can easily spread through networks, it’s essential to keep backups on isolated networks. Furthermore, it’s important to have multiple backups stored on different mediums to safeguard your data.

Beware of Email Threats: Malware distribution through email is a common method, and it’s easy to become a victim of such attacks. Even a momentary lapse in attention, such as not verifying a link correctly, can lead to an infection. Therefore, always hover over links to confirm their destination and, if in doubt, seek assistance from an IT professional.
