Every second counts when it comes to IT support, as unresolved issues can quickly become costly. And speed is something which Ophtek prides itself on.

The digital business landscape of the 21^st century is wide-reaching and informs countless business decisions throughout the day. From emails through to data storage and on to cybersecurity defenses, your IT infrastructure is crucial. Therefore, when there’s an issue with your IT systems, you need these to be resolved quickly, otherwise the financial impact – especially with cybercrime – can be significant.

The Impact of Downtime

Anything which creates an issue for your operational processes is going to have a financial impact. Say, for example, your data storage solutions fail, this is going to restrict the amount of data you have available. This could easily impact your operations by disrupting the way in which you retrieve customer data. Deliveries, which require customer details such as delivery addresses, could be put on hold. This scenario would instantly compromise your ability to invoice, with customers unlikely to pay for goods not received on time.

Likewise, if your email server were to become compromised by threat actors, you risk not only exposing your customers’ data, but also losing a major communication channel. This is a double-edged threat and, again, represents a major financial risk. Aside from your customers taking legal action against you for data violations, there’s the fact you could miss key communications from your customers and suppliers.

Every minute of downtime has the potential to push your business backwards, and it’s vital you can counter this effectively.

Minimize The Impact with a Speedy Response

It’s clear that IT is important for organizations to conduct their day-to-day operations, and any disruption to this will have major ramifications. The best way to minimize this is by ensuring you can launch a quick response. This will reduce your downtime and allow your organization to get its business operations back on track. Furthermore, it will minimize any financial risk e.g. allow you to resume order processing and any billing processes. And in today’s competitive business landscape, this is essential.

The best way to plan and execute quick IT support response claims is by partnering yourself with an established IT support provider, such as Ophtek. With a long track record of providing speedy and professional support, we can ensure that any IT downtime is kept to a minimum. Nonetheless, you can still put measures in place to help minimize your IT issues and facilitate our response:

Regular training: IT issues need to be reported, but you need to make sure that your team members know when to identify issues which require an IT professional. A malware threat, for example, always needs reporting, but something minor such as selecting a default printer in Word can probably be dealt with in-house.
Provide contact numbers: the members of your organization need to know who to contact in the case of an IT emergency, so these contact details need to be made available to every member of staff. A simple way of achieving this is by creating a contact in your phone systems, but it’s also a good idea to display a contact number on every user’s desktop.

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.

Limit data access: it’s important you only allow data to be available to those who need it. After all, there’s no reason why your marketing team, for example, need access to your clients’ financial data. Therefore, you need to identify the data you hold and the individuals who need access to it. By restricting access, you’re safeguarding this data against being mishandled unnecessarily.

Internal audits: to ensure you’re adhering with data governance, it’s a good idea to carry out regular data audits. These are crucial for ensuring data accuracy, compliance, and security. Also, an internal audit is the best way to identify vulnerabilities in your data systems and put procedures in place to mitigate these.

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.

Threat actors have compromised 70,000 previously legitimate websites and created a powerful network capable of distributing malware.

Named VexTrio, this network of compromised websites appears to have started in 2017, but it’s only more recently that details around its activity have emerged. As well as distributing malware, the VexTrio network also utilizes phishing pages, and allows the VexTrio hackers to harvest login credentials. The campaign is a significant one, and one which is powerful enough to cause harm to anyone who gets caught up in its operations. Therefore, it’s time to take a look at the VexTrio campaign to see what we can learn.

Understanding the VexTrio Network

The VexTrio campaign relies on a malicious traffic distribution system (TDS) to lead unsuspecting internet users to compromised websites. A TDS is, in simple terms, a web application used to analyze and filter incoming traffic and, following the analysis, redirect it to a specific page. Typically, the activities of a TDS are facilitated by malvertising activities or malicious websites. VexTrio favors using malicious websites.

Working with a number of affiliates, many of whom offer access to hijacked websites, VexTrio has managed to amass a sizeable network over the last seven years. And VexTrio are very much the middle-man in the operation. For a fee, VexTrio will feed incoming traffic through their TDS and forward innocent victims towards the websites they’re mostly likely to be interested in. It’s very similar to legitimate advertising networks, but with a vicious sting in its tale.

The malicious websites which comprise the VexTrio network contain a wide range of threats. For example, one of the affiliates, known as ClearFake, tricks users into downloading what is claimed to be a browser update, but is little more than malware. SocGholish, another well-known malware threat, is part of the VexTrio network and uses it to push unauthorized access to corporate websites.

Don’t Fall Victim to VexTrio

The threat of VexTrio is a substantial one, and organizations need to be aware of the damage it can cause. Luckily, you can protect yourself and your IT systems by implementing the following best practices:

Use an adblocker: you can minimize the risk of being lured to a malicious website by installing an adblocker on your systems. Not only will this block annoying popups, but it will also block any malvertising threats from being activated. These adblockers are usually available as browser extensions e.g. Ghostery and AdBlock for Chrome.
Disable JavaScript: attacks launched through VexTrio often rely on JavaScript to execute their malicious tasks. Accordingly, disabling JavaScript will eliminate the chances of such an attack taking place on your system. However, JavaScript is essential for many legitimate websites, so it’s recommended that you allow it to run only on trusted sites.
Install anti-malware tools: if you install an anti-malware app, such as AVG, you benefit from tools which block malicious websites. These tools are connected to databases which are constantly updated to identify and block malicious websites, such as those featured in the VexTrio network.

HeadCrab Attacks Servers with Advanced Malware

Mar 2024

A new strain of malware, which contains several different attack methods and is considered a severe threat, has been discovered and named HeadCrab.

The attack focuses its efforts on Redis servers, an open source, in-memory data structure store. In simpler terms, Redis acts as a database, cache, and message broker application which can store data, cookies, and authentication tokens. This means it contains confidential and personal data, which is a currency valued highly by threat actors. Redis is incredibly popular and used by many high-level clients, some of whom include Amazon, Adobe, OpenAI, and Airbnb. Therefore, it’s likely you and your team will visit websites using Redis servers, and you need to stay safe.

Unpacking the HeadCrab Attack

Redis servers appear to have been targeted by HeadCrab due to the fact they’re often exposed to the internet, without any solid authentication in place to protect them. This makes them highly vulnerable and puts any data stored on them at high risk. Using advanced coding techniques, the threat actor starts by taking control of a Redis server. This allows them to then download HeadCrab onto the infected server. This, as the command logs reveal, is a complex process, and one which leaves no stone unturned, highlighting the advanced skills of the threat actor.

With HeadCrab now active on the Redis server, it can get to work. Security researchers, who have reverse engineered HeadCrab, have discovered eight custom commands contained within its module. These allow HeadCrab to set up encrypted communication channels, reconfigure Redis servers, run exclusively in memory to avoid detection, and even run its own blog detailing its current activities and news.

Staying Safe from HeadCrab

Currently, HeadCrab has been detected in over 1200 servers and represents a serious threat. It doesn’t launch its attack using files, instead relying on advanced hacking techniques, so it’s a difficult threat to combat. However, by staying vigilant, your organization can stay safe against the threat of HeadCrab and similar attacks. The best ways to achieve this are:

Run security scans: using scanning tools contained within software, such as AVG and McAfee, gives your organization the opportunity to discover and nullify malware threats. These scans can be automated and provide you with real-time updates of the scan results. Many of these applications are available in freeware versions, with paid subscriptions allowing you to access more powerful security options.
Use authentication: you may not operate Redis servers, but the HeadCrab attack serves as a cautionary tale for failing to install strict authentication protocols on your servers. This extra layer of security ensures that only those users who are known to your organization can directly access your servers. This minimizes the chances of rogue commands being received by your IT infrastructure by threat actors.
Employ runtime monitoring: it’s important to use runtime monitoring to constantly analyze your IT system’s behavior and performance. This gives you real-time visibility into the operations of your infrastructure, and you can use these metrics to identify suspicious behaviors – such as data packets being sent to unknown addresses – and take actions.

Russian hackers are using a fake PDF decryption tool to trick innocent PC users into downloading Spica, a new strain of malware.

Discovered by Google’s Threat Analysis Group (TAG), Spica is a backdoor malware which has not been identified previously. It’s believed that the malware is the result of ColdRiver, a Russian hacking team with a proven track record in deploying malware. The attack, as with so many contemporary threats, is delivered by email and relies on malicious PDF files. Now, with close to 350 billion emails sent per day in 2023, it’s clear that email is hugely popular. And it’s estimated there are 2.5 trillion PDF files currently in circulation. Therefore, the chances of your business running into a similar attack is high.

The Threat of Spica

The Spica attack begins when the threat actors send a series of PDF files to their targets. Using phishing email techniques, they attempt to trick the targets into believing that these have been sent by legitimate contacts. These files appear encrypted and, if the target bites, they will email back to say they can’t open the files. This is where the threat actors are able to launch their payload.

By sending a malicious link back to the target, the threat actors can trick them into downloading what they claim is a decryption tool. However, this executable tool – going under the name of Proton-decryptor.exe – is far from helpful. Instead, it will provide backdoor access to the target’s PC. With this access in place, the malware can communicate with a control-and-command server to receive further instructions.

And Spica comes loaded with a wide range of weaponry. As well as being capable of launching internal shell commands on the infected PC, it’s also programmed to steal browser cookies, send and receive files, and create a persistent presence on the machine. Google believes that there are multiple variants of Spica, and the current targets of the malware seem to be high ranking officials in non-governmental organizations and former members of NATO governments.

Shielding Yourself from the Threat of Spica

While your organization may not be listed high on ColdRiver’s target list, the attack methods are familiar and could easily be launched against you at some point in the future. Therefore, it’s in your best interests to integrate the following advice into your cybersecurity measures:

Always double check attachments: with email attachments representing one of the surest ways to transmit malware, it’s vital you remain vigilant. If you have even the slightest inkling that something seems suspicious with an email from a known contact, don’t email them back. Instead, contact them by phone to confirm the email is genuine, as it may be that their email account has been hacked.

Check for spelling/grammar errors: phishing emails are prone to poor grammar and spelling, especially when they originate from non-English speakers. Accordingly, poorly composed emails should be scrutinized closely. Also, watch out for generic and unusual greetings such as “Dear customer” as these may indicate that the email is part of a mass-campaign against unknown targets.

Use email filters: by using email filters, often included with anti-malware software such as McAfee, you can provide your organization with an extra layer of security. Connected to databases which are regularly updated, these email filters can identify malicious files before they’re downloaded to your PC.
