The impact of the Covid-19 can still be felt, with high numbers of employees continuing to work remotely. But how does this affect your cybersecurity?

The shift towards remote work was essential at the start of the pandemic, and it has now become a permanent aspect of many employees’ lives. However, while it represents a flexible approach to work, which helps achieve a healthy work/life balance, it also comes with challenges in terms of cybersecurity. With employees working from different locations and connecting to your IT infrastructure from different networks, it’s a complex scenario to manage.

Staying Secure in the Remote Work Era

It’s important your organization takes the necessary steps to strengthen their defenses when it comes to remote working practices. Many of these are simple and can be implemented easily. Therefore, you need to make sure you follow these best practices:

  • Avoid Public Wi-Fi: remote working allows your employees to work from anywhere, but this can open them and your servers up to significant risk. In particular, the risk of public Wi-Fi networks – such as those found in coffee shops and public places – should never be underestimated. With little protection in place, these Wi-Fi networks can easily be compromised and risk your organization’s data being harvested. Therefore, your remote employees should be discouraged from using these, instead using secure networks at home.
  • Use Multi-Factor Authentication: For remote workers, extra layers of security are everything when it comes to protecting your networks. And this is why multifactor authentication can be a real game-changer in terms of your security. Furthermore, biometric authentication such as Windows Hello allows your business to enhance its security and prevent unauthorized access.
  • Use Secure Collaboration Tools: You have to think a little differently when working with remote employees, especially when it comes to collaborating. It’s not as simple as having your entire team in the same room, so collaboration software is crucial. However, this needs to be secure. So, make sure you use secure collaboration tools such as Microsoft Teams, Slack, and Basecamp to ensure your communications remain encrypted and safe
  • Monitor Remote Devices: With your remote employees’ devices out of sight, they need to be monitored closely. Endpoint monitoring software allows you to track devices in real time and identify any unusual behaviors. Automatic alerts and notifications can be put in place to ensure you’re aware of any breaches immediately and allows you to take action to neutralize any threats.
  • Employee Training: As ever, the most important aspect of cybersecurity for businesses involves employee training. Accordingly, your remote employees need specific training to make sure they understand the risks of remote work. Strong and unique passwords, for example, have never been more important, and being able to identify phishing attempts is equally crucial when an employee is unable to call on the immediate support of their colleagues.

Digital data is perhaps the most valuable asset your organization handles, but just how secure, safe, and compliant is it?

Data governance is a crucial element of business IT and one which businesses must comply with. It gives both accountability and responsibility to the data owners, ensuring sensitive data and privacy is correctly handled. This governance can either be internal – such as data policies specific to an organization – or external, such as government or regulatory bodies. The objective of data governance is to secure data and make sure it’s not misused.

Naturally, with cyber crime showing no signs of slowing up in 2024, it’s vital you have a firm understanding of data governance for business IT.

What is Data Governance?

Data governance is a complex set of procedures and policies which can be difficult to get to grips with. However, the basics are simple to understand. A simple explanation for data governance is that it focuses on the strategic management of all the data you hold. By monitoring your data and the way in which it is used, you build defenses around that data. This allows you to minimize the risks associated with data breaches, build trust among your stakeholders, and assist with informed decision making around your data.

The Importance of Compliance

Many industries are governed by strict regulatory requirements e.g. the healthcare industry needs to adhere to the strict framework put in place by HIPAA regulations. Regardless of the industry or regulatory framework, the aim of compliance remains the same. By demonstrating adherence to compliance, you’re underlining the fact that any sensitive data you hold is protected and handled correctly. If your organization fails to hit the benchmarks laid out by external bodies, then you run the risk of some eyewatering financial penalties.

Improving Your Data Security

The best way to maximize your compliance and governance is to enhance your data security. You can achieve this in the following ways:

  • Employee training: one of the most common causes of data breaches is your employees. These are the individuals who are most at risk of falling victim to social engineering, phishing emails, and malvertising threats. Accordingly, you need to implement a robust training schedule for new starters and, for all staff, follow up with refresher courses.

Final Thoughts

With the rise of big data in business, it’s clear that good data governance practices should be a priority for any business. This will allow you to build a strong foundation of data governance to protect both your organization and your customers.

Healthcare data is some of the most sensitive and confidential data to exist in IT systems, so the ransomware attack at Norton Healthcare is a big deal. 

Based in Kentucky, Norton Healthcare is a provider who delivers health services to adults and children in over 40 clinics. Their objective, as with all healthcare providers, is to improve the lives of their patients. However, a recent data breach has done little to inspire a sense of wellness in their patients. The breach, which occurred in May this year but is only just being reported, was part of a ransomware attack. Norton Healthcare’s network was breached for two days, but there appeared to be no evidence that their medical record system had been accessed. 

Nonetheless, healthcare data should always be secure, and breaches in local networks represent a major cause for concern. 

The Norton Healthcare Attack 

The exact nature of the attack has, at present, not been released. But we do know what the impact of the breach was. After discovering that an attack was taking place, Norton was forced into turning its network off, the last thing a healthcare provider wants to do. As the attack was unfolding, Norton received, in a novel twist, a faxed ransom note featuring threats and demands. Later that month, a ransomware group known as ALPHV claimed responsibility for the attack. 

ALPHV released a statement to the dark web which claimed that they had managed to compromise 4.7TB worth of data from Norton Healthcare’s servers. As proof, ALPHV uploaded numerous files – containing patients’ bank statements and Social Security numbers – to backup their claims. Norton’s official line is that only some network storage devices were breached, and these only contained identifying information rather than any medical data. 

How Can Healthcare Providers Protect Themselves?

With more and more healthcare providers coming under attack from threat actors, it’s important that they understand how to minimize their risk. In fact, these lessons are valuable for any business running an IT network, so it’s time to find out how. So, to stay safe from ransomware attacks, make sure you follow this best guidance: 

  • Regular backups: it’s vital that you perform regular backups of your data to ensure, if it becomes encrypted by ransomware, you still have access to it. Ideally, these backups should be completed daily at the very least, and they should always be saved to secure locations. It’s important to keep copies of your backups offline as well, this will allow you to access your data even if you need to take your network down. 
     
  • Partition your hard drives: to minimize the impact of a breach, it’s a good idea to partition you hard drives and data storage. By separating these from your main network, and from each other, you’re limiting the files and data that malware can access. This minimizes the risk of data loss and allows you to keep important systems online. 
     
  • Employee training: educating your staff about the dangers of social engineering and phishing emails is one of the most important steps you can take. Ransomware, such as the strain encountered by Norton Healthcare, is often spread through emails and your employees need to be able to identify these threats before clicking on them.

Social engineering is one of the modern menaces of online life, and this has been demonstrated by a recent malware attack on a Swedish camera firm.

Axis Communications, who manufacture network and security cameras, are the company at the centre of this recent attack. The organization announced that they had been the victims of what they described as an “IT-related intrusion” and advised that, as a result, they had temporarily closed their public-facing services online. Naturally, the attack caused great disruption to Axis; it also brought to light a number of shortfalls in cyber-security, namely the impact of social engineering.

What is Social Engineering?

Social engineering is a form of hacking which involves using various methods of deception to glean information from the victims. So, for example, an employee who receives an email, from what appears to the organization’s IT department but is from a fake email address, asking for confirmation of their login credentials is a form of social engineering. And these incidents of social engineering don’t have to take place online, simply telling someone your mother’s maiden name – a popular choice for password recovery questions – is another example.

How The Axis Attack Happened

The exact details of the Axis attack are yet to be released as the company are conducting a forensic investigation intoexactly what happened. Nonetheless, they have revealed the following details:

  • Several methods of social engineering were used in order to gain access to the Axis network, these were successful despite the presence of security procedures such as multi-factor authentication.
  • Advanced hacking techniques were used by the hackers – once they had breached the network – to enhance their credentials and gain high-level access to restricted areas.
  • Internal directory services were compromised by this unauthorized access.
  • While no ransomware was detected, there was evidence that malware had been downloaded to the Axis network.

Following concerns of suspicious network activity, and the employment of IT security experts, all external connectivity to the Axis network was closed down.

How to Protect Yourself from Social Engineering

It can be difficult to tackle the highly polished social engineering methods employed by hackers, but following the practices below can make a real difference:

  • Always Think: slowing down and assessing the situation is crucial when it comes to social engineering. If someone has asked you for sensitive information, such as password details, ask yourself why the need this and what could they do with it? Internal sources – such as managers and IT departments – will never ask for this, so guard your password carefully and, to clarify the situation, speak face-to face with the person who has apparently asked for it.

Feb 2022

British shoppers have been warned to expect some of their favorite snacks to be in short supply following a ransomware attack on a major manufacturer.

KP Snacks has been producing snacks in Britain since the 1850s, but this production has recently run into a major obstacle: ransomware. Cyber criminals have successfully launched a ransomware attack on KP Snacks, and its effects are running deep. Due to the impact of the ransomware on their IT infrastructures, KP Snacks has had to advise stores that delays in production are expected. As a result, British shoppers are likely to be facing empty shelves when they head out to pick up their favorite snacks.

Snack food may not be crucial to society, but the impacts of this hack demonstrate why organizations need to remain vigilant.

The Story Behind the Snack Attack

Following an unexplained outage of their IT systems, KP Snacks investigated and discovered that they had fallen victim to a strain of ransomware. The exact details of the ransomware in question has not, as of yet, been disclosed. However, rumors are circulating that the attack was launched by the WizardSpider group, a gang of hackers who attacked the Irish health service in 2021. It’s alleged, according to leaked sources, that KP Snacks was given five days to pay a ransom fee, but clarification on this is lacking.

The response of KP Snacks has been to launch a defensive strike against the attack. Being a major organization, the snack makers had a cybersecurity response plan which was quickly put into action. Third-party security experts have also been drafted in to complete a forensic analysis of the firm’s IT infrastructure. Nonetheless, the disruption to productivity has hit KP Snacks hard. As well as their IT systems being compromised, their communications systems have been hit equally hard. In modern business, these two elements are essential for operating and, as a result, supply shortages are expected.

Protecting Yourself Against Ransomware

While a shortage of snacks may sound like a mild inconvenience, this is only the tip of the iceberg. Not only is there a financial risk for KP Snacks, but the company’s employees can also expect financial ramifications e.g. delayed payments due to compromised IT systems and even the threat of redundancy. Naturally, this is a situation that no organization wants to find itself in, so make sure you always follow this advice:

  • Always Backup: the main impact of ransomware is that it encrypts files before demanding a ransom fee to decrypt them. However, you can minimize the impact of this effect by ensuring you have a strong backup strategy in place. This will provide you with access to your data and provide you with business continuity.
  • User Training: ransomware can be activated in a number of different ways such as infected emails, malicious links and running outdated software. Thankfully, shutting these attack routes down is relatively easy with the correct training. Therefore, regular staff training is vital when it comes to securing your IT defenses.
