Businesses should always be trying to optimize their IT infrastructure. A fter all, not only will this improve efficiency, but it will also cut costs.

In the dynamic and competitive landscape of business, a highly tuned IT infrastructure can be the difference between success and mediocrity. T herefore, if you truly want an infrastructure which fosters both smooth daily operations and capacity for growth, you need to start optimizing your operations. This may sound like a monumental task, but luckily Ophtek are here to help make this job easier with 5 ways to optimize your business IT infrastructure.

1. Strengthen Your Cybersecurity

In a world of ever evolving cyber thre ats, it’s crucial that your IT infrastructure is secure. Therefore, you need to start by strengthening your existing cybersecurity protocols. Begin by conducting regular security audits to ensure that you can monitor your defenses in real time. This means that, for example, if your firewall is no longer adequate against contemporary threats, you will know that it needs replacing with a more suitable solution. Additionally, never underestimate the impact of employee training programs to teach them the best security practices.

2. Calibrate Your Network Configuration

M aintaining a smooth flow of data acros s an organ ization’s network is essential. Accordingly, you should be mindful of fine tuning your network settings to achieve this. Optimizing your bandwidth usage and reducing latency are two of the most important steps you can take to improve performance. Sometimes, this will be as simple as simply adjusting network settings to cope with demand, but if a prolonged and heavy demand is forecast, investing in more sophisticated hardware may be required.

3. Be Energy Efficient

IT infrastructures use a lot of energy, and this can lead to significant outgoings in energy costs. Therefore, researching and investing in energy efficient hardware is one of the best practices you can implement. So, for example, i f you invest in more energy efficient data centers, not only will you benefit from lower running costs, you will also be spending less on cooling the data centers. And, best of all, as well as helping your finances, it also enhances your green credentials and benefits the environment.

4. Automate Routine Tasks

One of the best ways to optimize your IT operations is by automating repetitive and routine tasks. This approach can be applied to numerous tasks such as software updates, network monitoring and security tasks. As well as saving time, automation eliminates the risk of human error. This means that your IT demands are completed more efficiently and your human resources can be allocated to more complex activities which cannot be automated.

5. Never Forget Scalability

F inally, it’s vital that you design your IT infrastructure with scalability in mind. Business requirements can change rapidly, and your IT operations need to keep pace with them. This can cover increased demand for user numbers, application changes, or data volume. Whatever the requirements, your IT architecture needs to be able to adapt to these changes if you want your business to grow. So, make sure you thoroughly assess your existing and future needs, embrace cloud computing, and monitor your infrastructure’s performance.

Nov 2023

Back in 2020, a new banking trojan by the name of BBTok emerged into the digital landscape and was responsible for numerous attacks. And now it’s back.

Banks in Brazil and Mexico appear to be the main targets of BBTok’s new campaign, and it’s a variant which is far more powerful than any of its previous incarnations. Its main deceptive threat is that it is able to spoof the interfaces of 40 different banks in Brazil and Mexico. This means that it’s perfectly placed to harvest sensitive data. In particular, this new strain of BBTok is deceiving victims into disclosing their credit card details and authentication codes. This gives the campaign a financial angle and highlights the serious threat it poses.

How Does BBTok Launch Its Attacks?

BBTok’s latest strategy begins with a phishing email, one that contains a malicious link which kickstarts the attack by launching the malware alongside a dummy document. BBTok is particularly successful as it has been coded to deal with multiple versions of Windows, and it also tailors the content of the attack to both the victim’s country and operating system. BBTok also allows the threat actors behind it to execute remote commands and steal data without the victim being aware.

Most notably, however, is the way in which BBTok replicates the interface of numerous banking websites – such as Citibank and HSBC – to truly deceive the victim. Appearing to be genuine at first glance, these interfaces are used to trick victims into entering security codes and passwords associated with their accounts. This gives the threat actors full access to their financial data and, more disturbingly, full control over their finances. This means that unauthorized payments and bank transfers can quickly land the victim in severe financial trouble.

How to Stay Safe from Banking Malware

In an increasingly digital world, where we all make numerous financial transactions online every week, it’s important to remain guarded against banking malware. As well as the financial damage that malware such as BBTok can cause, it can also create a foothold for threat actors to delve deep into your networks. And this represents a major threat to the security of both your data and your customer’s data. Accordingly, you need to stay safe, and here are some crucial tips to help you:

Beware of phishing emails: your employees should always be cautious when opening emails or clicking on links from unknown sources. As with BBTok, many banking trojans spread through phishing emails which trick you in to visiting fake banking websites. This provides threat actors with the perfect opportunity to harvest your credentials. Therefore, make sure that your employees know how to quickly identify a phishing email and what to do with them.
Install a firewall: putting a firewall in front of your network is a vital step in strengthening your digital defenses. Firewalls act as keen-eyed gatekeepers who scrutinize incoming and outgoing traffic, this allows them to determine whether traffic is trusted and whether any alarms need to be raised. Banking trojans, of course, often transmit stolen data out of your network, so a firewall is the perfect way to identify and prevent this activity.
Strong endpoint security: to protect your network against malware, it’s essential that you employ robust cybersecurity measures throughout your business. In particular, employee workstations and mobile devices are most at risk, so installing advanced antivirus and anti-malware software here should be a priority.

Nov 2023

A major ransomware attack on the MGM brand of casinos has led to the firm’s IT systems having to be shut down.

The ransomware-as-a-service hacking group BlackCat has taken responsibility for the attack, and it’s an attack which has caused major issues for MGM. IT systems responsible for processing electronic payments, digital key cards, parking systems and ATMs have all been impacted by this attack. While the attack is considered major, it was executed by the simplest of means. As ever, this attack on MGM contains some important lessons for organizations to learn and enforce.

How Were the MGM Casinos Hacked?

The MGM attack was made possible by the use of social engineering techniques. In particular, BlackCat identified an MGM employee by scouring related profiles on LinkedIn. With this information at their disposal, the threat actors contacted the MGM help desk and used this employee’s details as their way into the system. The exact nature of the breach, for security reasons, has not been disclosed, but it’s believed that it only took 10 minutes for BlackCat’s strategy to be successful.

BlackCat, with full access to MGM’s IT infrastructure, set about issuing demands to MGM through a secure communication channel they had put in place. However, MGM refused to pay any of the ransom fees demanded by BlackCat. Instead, on the recommendations of their security team, MGM began shutting their Okta servers – used for authorization processes – down.

However, BlackCat were able to remain active on the network due to the administrator privileges that they had gained during the attack. And, in response, BlackCat set about compromising over 100 hypervisors – applications which are used to manage virtual machines located on a PC – and encrypting the data contained on them.

BlackCat, again, brought their ransom demand to the table and also threatened to launch further attacks if this was not met.

How Could MGM Have Protected Their IT Systems?

As a thriving, world-famous organization, MGM could have done without the headlines relating to the attack by BlackCat. And, as with all social engineering attacks, this could have easily been avoided if MGM had practiced the following:

Be skeptical: unsolicited requests for information should always be treated with caution. If personal information is being requested, then always question the person, even if they appear to be legitimate, asking for the information. More importantly, take steps to verify their identity through official channels to confirm their authenticity.
Educate your team: it’s important that you familiarize your team with the most common social engineering tactics such as phishing emails and baiting. Awareness of these techniques will allow your staff to recognize these manipulative techniques before they can execute their malicious payloads.
Protect personal information: it’s crucial that you always protect sensitive data such as passwords, financial details, and personal identification. Avoid sharing such information with strangers or unverified individuals, such as on social media sites – as social engineers often harvest these channels to discover vulnerabilities.

A Remote Access Trojan (RAT) is one of the most common forms of malware you are likely to encounter, and it’s crucial you understand what they are.

It’s important for all organizations to be aware of the danger posed by a RAT in terms of cybersecurity. After all, a RAT could easily take down your entire IT infrastructure or compromise your business data. And all it takes is one mistake for your team to fall victim to a RAT. Due to the severity posed by RATs, we’re going to define what a RAT is, how they work, and the best way to defend and protect against this threat.

The Basics of a RAT

A RAT is a strain of malware which is designed to give threat actors unauthorized access and control over a victim’s PC from a remote location. This is always completed without the victim’s consent, a fact made possible by the stealthy nature of a RAT.

For a RAT to succeed, it first needs to infect the victim’s PC, and this can be achieved in the following ways:

Phishing emails may be used to send malicious attachments which, once opened, activate the RAT and allow it to access the PC it is on.
Malicious downloads may be activated by unsuspecting users who are downloading them from illegal file sharing websites.
If hardware and software is not updated regularly, there is a chance that vulnerabilities may be discovered which a RAT can exploit.

RATs are stealthy types of malware and this cloak of invisibility is put in place by changes that the RAT makes to system settings and registry entries. With this deception in place, a RAT is then able to communicate to a command and control (C&C) server located in a remote location. This C&C server allows the RAT to transmit stolen data and, at the same time, gives the threat actor the opportunity to send commands directly to the RAT.

Some notable examples of RATs are ZuroRat from 2022, NginRAT from 2021 and, more recently, the QwixxRAT attack. All of these examples share one key thing in common: their main objective is to cause digital chaos for all those who fall victim. Accordingly, your organization needs to understand how to defend themselves against these threats.

Detecting and Protecting Against RATs

Protecting your IT infrastructure is far from difficult. In fact, as long as you implement the following measures, it’s relatively easy:

Always update your antivirus and anti-malware software. These security suites have the potential to put a strong barrier in place and detect any incoming malware. However, they also rely on regular updates to keep up to date on the latest threats. Therefore, you need to make sure these are put in place to maximize your defenses.
Make sure that network monitoring solutions are implemented to combat unauthorized network access. This means that your IT team will be able to identify unusual network traffic patterns and take actions to shut this down.

Email and web filtering can seriously reduce your risk of falling victim to a RAT. These excellent pieces of software will analyze and block any malicious attachments before they have a chance to reach your email inbox.
