No IT infrastructure is 100% secure, but you can maximize your defenses and reduce your risk. All you need to do is complete an IT vulnerability assessment. 

It’s important to understand exactly what your cybersecurity procedures can and can’t protect against. After all, assuming that your security measures are perfect is a sure-fire way to become complacent. And if there’s one thing that threatens the safety of your IT systems, it’s complacency. Therefore, it’s essential you understand why you need to complete an IT vulnerability assessment. And, more importantly, that you know how to complete one. 

Understanding the Purpose of a Vulnerability Assessment 

A vulnerability assessment looks at your IT infrastructure and reviews each and every security procedure, as well as highlighting any potential weaknesses. This pre-emptive approach is critical for reducing risk and protecting your systems. Its main objective is to evaluate your existing procedures and deliver suggestions for future improvements. 

Preparing an Assessment 

There are several steps when it comes to preparing an IT vulnerability assessment, and these include: 

Analyzing Your Assessment 

Once all your preparation is in place, you can complete your assessment as per your plan and guidelines. You then need to analyze the results of your assessment. As previously stated, no IT system is 100% secure, and your assessment will likely raise several concerns and vulnerabilities. Therefore, you will need to categorize these vulnerabilities both by area and severity e.g. weak firewall defenses (major) and staff writing passwords down (medium). This will allow you to begin planning a mitigation strategy to nullify these threats. 

Implementing a Mitigation Strategy 

With the information gleaned from your vulnerability assessment, it’s vital that you begin communicating this with the stakeholders within your organization. Ensure that your IT staff, department managers and executives are all aware of the vulnerabilities. Most importantly, also communicate how these will be mitigated, this will keep everyone on the same page and generate discussion on any potential implementation problems. 

Finally, you need to put your mitigation strategy into place. These steps will vary, depending on your vulnerabilities, but common examples include additional training sessions for employees, updating software and upgrading legacy equipment. Whatever the plan, speed is of the essence to prevent these vulnerabilities turning into a catastrophe.

May 2023

At the start of March 2023, a new National Cybersecurity Strategy was launched by the Biden administration. And it promises big things. 

The previous National Cybersecurity Strategy was released by the Trump administration in 2018. However, since then, the world and the internet has changed significantly. An updated strategy makes sense. But what exactly does it seek to change about the way in which we access and navigate our way through the internet? Well, for one thing, it starts by stating that the Biden administration will be investing $65 million in order to provide every American with access to high-speed internet. 

In terms of cybersecurity, however, the 2023 strategy tackles a much broader range of problems

The Ins and Outs of the 2023 National Cybersecurity Strategy 

The paper which outlines the 2023 National Cybersecurity Strategy is 35 pages long. It’s also a complex read. But this doesn’t mean the main takeaways are exclusive to high-level IT experts. This is why we’ve decided to help you by breaking down the five pillars that the paper covers: 

  1. One of the major priorities of the 2023 strategy is to secure our critical infrastructures. This means that essential systems and networks – such as energy grids and water supply systems – are at risk from cyberattacks. And, just imagine, if a group of threat actors disrupted power supplies, it would result in a major catastrophe. Therefore, the Biden administration is aiming to foster collaboration between government agencies and other stakeholders to identify and protect against any vulnerabilities. 
  1. Strengthening our cyber defenses and disrupting threat actors has been identified as a major area for the 2023 strategy to cover. This involves developing strong cybersecurity policies, ones which can quickly detect and respond to cyber-attacks. Once developed, these policies need to be implemented as seamlessly as possible to protect our networks. Naturally, investment in technology and skilled staff will feature heavily in the success of this second pillar. 
  1. The third pillar of the new National Cybersecurity Strategy seeks to make market forces drive security and resilience. This means that companies which own personal data will be expected to develop more secure storage systems, and existing laws will be updated to protect users against the risk of software vulnerabilities. The aim of this pillar is to ensure that developers need to foster higher standards of care. The result will be a safer digital landscape. 
  1. Investment is crucial in any area seeking to make improvements, and the internet always needs improvements. Accordingly, the Biden administration is seeking to improve three key areas: computing technology, clean energy technology and biotechnology/biomanufacturing. This pillar is also concerned with strengthening the US cyber workforce through enhanced education and digital awareness. 
  1. The final pillar in the 2023 strategy focusses on the importance of international partnerships to pursue shared goals. After all, the US alone cannot stop the rise of cybercrime. Common threats need to be addressed by sharing resources and pooling knowledge. The end objective is to deliver higher levels of assurance that digital systems and platforms are safe and secure. 

The latest National Cybersecurity Strategy continues the excellent foundations put in place over the last two decades. It’s a responsible step for the Biden administration to take and, at the very least, will provide peace of mind that the internet remains, on the whole, safe to use.

Wiper malware attack on Sony Pictures

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:

Jan 2023

With the end of 2022 fast approaching, it’s time to start looking ahead to the potential security threats that hackers are planning for 2023. 2022 has been another year packed full of ransomware, deceptive malware and unbelievable software vulnerabilities, so it should come as no surprise that more of the same lies ahead. However, threat actors are constantly evolving their techniques and strategies to stay one step ahead of your defenses. Accordingly, you need to make sure you’re keeping pace with their advances and, where possible, putting solutions in place ahead of any attacks being launched.

Preparing for cybersecurity threats in 2023 is vital if you want to keep your IT infrastructure safe for the next 12 months, so let’s look at what we’re likely to be fighting against.

What’s in Store for 2023?

There will be many threats during 2023 to look out for, but the 5 biggest cybersecurity threats you need to be aware of are:

Ransomware will push onwards and upwards: one of the biggest threats to cybersecurity over the last 10 years has been ransomware, and it’s a trend which will continue in 2023. In particular, it’s believed ransomware will move its focus towards cloud providers rather than single organizations, a move which will allow threat actors to target multiple organizations based within one platform. Additionally, due to the speed with which it can be completed, it’s likely ransomware will concentrate on file corruption as opposed to full encryption.

Artificial intelligence will become more important: whilst the potential for AI to help organizations is immense, it also has the capability to fuel cyberattacks. Polymorphic code, for example, uses AI to rapidly change its code, a skill which makes it perfect for malware to avoid being detected. AI learning is also likely to be used to help threat actors to sniff out software vulnerabilities, an opportunity which will allow hackers to focus their real-time activities elsewhere.

Internet of Things attacks to increase: the Internet of Things (IoT) is only going to get bigger during 2023 and, given the historical security issues with IoT devices, this is going to create a small-scale nightmare for your network. As a result, more emphasis is going to be needed when working with IoT devices due to the increased surface area for hackers to target e.g. regular updates and inventory checks. Supply chains to be targeted more and more: supply chain attacks are very dangerous, and 2023 is likely to see a further increase in the number of attacks launched. Much like IoT attacks, supply chain attacks open a large surface area to threat actors, a point underlined by the SolarWinds attack which exposed hundreds of organizations to a single attack. Therefore, it will be crucial that software and hardware being released is thoroughly checked by its manufacturers to avoid any security disasters.

Social engineering to start working with deepfakes: the danger of deepfakes has been well documented in the last five years, but it’s possible these are now going to be integrated into social engineering scams. Deepfakes are all about deception and, at their best, they are highly convincing. Consequently, they are perfect for adding legitimacy to emails and videos which, for example, may be pushing for you to take a call-to-action which is a smokescreen for downloading malware.

US Companies Targeted by Black Basta Ransomware

Dec 2022

Companies in the US have recently found themselves under attack by the Qakbot malware, a campaign leading to numerous infections by Black Basta ransomware.

Black Basta is a ransomware group which first entered the digital waters in April 2022. Positioned as a Ransomware-as-a-Service (RaaS) group, Black Basta have been very busy in the months following their initial detection. Their attack strategy tends to focus on specific targets rather than hitting thousands of targets and hoping that some fall victim. Primarily, Black Basta have been observed to be using malware such as Qakbot and exploits including PrintNightmare to gain an initial point of entry to PC networks. From here, they ratchet up the chaos by installing ransomware.

Due to the financial risk associated with ransomware, it’s crucial your IT infrastructure is on high alert when it comes to the Black Basta attacks.

The Lowdown on Black Basta’s Campaign

At least 10 US-based companies have been attacked by Black Basta’s campaign in the last two weeks, and at the heart of its attack is a double-extortion method. Essentially, this strategy involves taking a standard ransomware attack (encrypting files and demanding a ransom) and adding further weight by threatening to publish the encrypted data on the dark web. Naturally, this is considered a very serious and aggressive threat, but exactly how does Black Basta take control of these networks in the first place? By launching a spear phishing attack, Black Basta is able to deliver a malicious disk image to unsuspecting victims which, if opened, activates Qakbot. This malware is then used to connect to a remote server and distribute Cobalt Strike, a legitimate piece of software which threat actors can use to set up numerous ‘beacons’ on a network. Once these beacons are established, Black Basta begins to steal credentials and launch ransomware attacks on the compromised network. A number of instances have also arisen where users are completely locked out of their network.

How to Protect Against Black Basta

This is far from the first ransomware attack to be launched, but it is considered a significant threat to PC users and the finances of organizations. Therefore, protecting your IT infrastructure against the Black Basta threat actors must be a major priority. As with most ransomware attacks you should be carrying out the following:

  • Be aware of social engineering: spear phishing attacks, such as those deployed by Black Basta, are incredibly deceptive and have the potential to hoodwink even the most vigilant employee. However, if your employees are encouraged to always take time to double check emails – e.g. links, uncharacteristic writing styles and unusual requests – then you will reduce your risk of falling victim to spear phishing.
  • Make multiple backups of your data: many organizations are forced into paying ransomware demands as it’s the only way to retrieve their valuable data. Backing up your data to multiple sources, however, ensures you have a copy of this data preserved. As a result, you can ignore the hackers’ demands and keep your finances looking healthier.
  • Install all updates: attacks similar to Black Basta’s recent campaign are often attributed to software vulnerabilities – such as the PrintNightmare exploit – so it makes sense to make sure all updates are installed as soon as they are available. It may feel like a small step to take, but it provides your IT network with a serious security boost.
