In the digital age, it’s crucial for your business to have a robust IT infrastructure if you want to achieve long-term success and sustainability.

An IT infrastructure, however, is a complex combination of services and components. Accordingly, building and maintaining one is far from straightforward. But if you want to support your day-to-day operations and build for future growth, it’s essential you prioritize your IT infrastructure. To help you get started, or evaluate your existing system, we’re going to take a closer look and how you can build and maintain it.

What are the Key Components?

A well-designed IT infrastructure will ensure your daily operations run smoothly, but what are the components supporting this success? The core elements comprising an IT infrastructure include:

  • Hardware: central to any IT system is the hardware, without which you wouldn’t have any IT capabilities. This hardware typically includes major resources such as servers for managing network activity, storage solutions for data management and backup, as well as networking equipment to support connectivity and security e.g. routers and firewalls.
  • Software: the backbone of your hardware will be software, which your team can use to process, store, and analyze data. This software can include operating systems such as Windows and Linux, or business applications which support core functions e.g. using Microsoft Excel to store data.
  • Network Infrastructure: depending on the size of your business, you may rely on Local Area Network (LAN) or a Wide Area Network (WAN). Generally, a smaller business will only need to work with a LAN, but larger businesses may work with several LANs connected to a main WAN. Both of these networks ensure there is a seamless data flow across your network.

Building and Maintaining an IT Infrastructure

Before you start operating across an IT infrastructure, you need to first build one and then establish a maintenance schedule. It’s an important process and one which requires great planning. So, to do this successfully, make sure you cover the following:

  • Carry Out a Needs Assessment: before investing in an IT infrastructure, perform a thorough assessment of your business needs. This involves understanding current and future requirements, identifying gaps, and setting clear objectives. It’s important to involve multiple stakeholders from your business in this activity, as well as working with IT experts to determine what’s viable.
  • Scalability: It’s difficult to predict future growth, but designing your IT infrastructure to be scalable is vital. This means selecting hardware and software that can grow with your business, allowing for easy upgrades and expansions when your business activity demands it.
  • Regular Maintenance: you should regularly update software and hardware to ensure optimal performance and security. Implement a maintenance schedule and keep up with the latest patches and upgrades. Remember, failing to implement security patches promptly can have catastrophic results for your IT security.
  • Monitor Performance: once your IT infrastructure is up and running, it’s important to monitor its performance. It’s very easy for small issues to escalate into major IT issues, so being proactive can help identify issues before they become critical.

Snowflake Passwords Leaked Online Due to Malware

Snowflake, a cloud data analysis company, has found itself under attack from malware, with the result that its customers passwords have been leaked online.

A leading cloud data platform, Snowflake was founded in 2012 and has experienced a rapid rise in the industry, with its current revenue estimated at $2.8 billion. This success has been founded upon innovative data analytics solutions and a number of leading clients such as Santander, Dropbox, and Comcast. For threat actors, Snowflake represents a tempting target, both in terms of the sheer amount of data they hold and financial value. And this is clearly why Snowflake has been attacked.

With threat actors claiming to have stolen hundreds of millions of customer records from Snowflake environments, the attack is clearly a significant one. Perhaps the most interesting aspect of the attack is that it appears to result from a lack of multi-factor authentication.

Cracking the Snowflake Infrastructure

Live Nation, a popular ticket sales service, was the first company to announce that their stolen data had been hosted on the Snowflake platform. Other Snowflake customers have come forwards to acknowledge a breach but are yet to name Snowflake as the hosts for this data. The attack appears to have been fueled by info-stealing malware, with the attack targeting PCs which had access to their organization’s Snowflake network.

How the initial attack was instigated remains unclear, but Snowflake has revealed that a demo account, protected with nothing more than a username/password combination, had been recently compromised. Whether this gave the threat actors direct access to Snowflake customer accounts is unknown, although it does point towards the threat actors establishing an early foothold. Snowflake has also disclosed that each customer is put in charge of their own security, and multi-factor authentication isn’t automatically enabled. This, Snowflake states, is how threat actors succeeded in hacking the compromised accounts.

Snowflake has advised all of its customers to switch on multi-factor authentication, but it appears to be too late for many. Whole lists of Snowflake customer credentials can be found available on illegal websites, with this data including email addresses alongside username/password combinations. Ticketmaster, another ticket sales platform, has been reported of having close to 560 million customer records compromised. This is a huge data breach, and one which has deservedly earned headlines.

The Importance of Multi-Factor Authentication

For Snowflake to have selected multi-factor authentication as an optional function, rather than a default security measure, is negligent. Regardless of this negligence, it’s also the responsibility of the compromised accounts to double check the available security measures. Therefore, to stay safe in the future, always carry out the following when working with external hosting providers for your data:

Malicious Microsoft Office Torrents Laced with Malware

Threat actors have been discovered to be using cracked versions of Microsoft Office to distribute a dangerous malware cocktail through illegal torrents.

Detected by the AhnLab Security Intelligence Center (ASEC), this malware campaign bundles together a collection of powerful malware strains – such as malware downloaders, cryptocurrency miners, and remote access trojans – to unleash a devastating attack. The malware is disguised as a cracked Microsoft Office installer, which would usually allow users to illegally download paid applications for free. However, those downloading this ‘cracked’ software are getting much more than they bargained for.

The Dangers of Malicious Torrents

Torrent sites, the use of which is generally illegal, have a long history of containing malware due to the unregulated nature of these sites. However, the promise of expensive software for nothing more than a few clicks is highly tempting to many internet users. Therefore, risks are taken and, occasionally, the consequences can be severe.

In this most recent example, torrents for Microsoft Office – as well as torrents for Windows and the Hangul word processor – are using professionally crafted interfaces to pass themselves off as legitimate software cracks. But despite the numerous options available, to apparently assist the user, these cracks have a nasty sting in their tail. Once the installer has been executed, a background process launches a hidden piece of malware which communicates with either a Mastodon or Telegram channel to download further malware.

This malware is downloaded from a URL linked to either GitHub and Google Drive, two platforms which are both legitimate and unlikely to ring any alarm bells. Unfortunately, there’s plenty to be alarmed about. A series of dangerous malware types are downloaded to the user’s computer, and these include Orcus Rat, 3Proxy, XMRig, and PureCrypter. These all combine to harvest data, convert PCs into proxy servers, download further malware, and use PC resources to mine cryptocurrency.

All of these malware strains run in the background, but even if they’re detected, removing them has little impact. This is because an ‘updater’ component of the malware is registered in the Windows Task Scheduler and, if the malware strains have been removed, they are re-downloaded on the next system reboot. This makes it a persistent threat, and one which is difficult to fully remove from your system.

Shield Yourself: Avoiding Harmful Torrents

Clearly, it’s crucial you need to protect your business from malicious torrents, but how do you do this? Well, it’s relatively simple if you implement the following strategies:

In today’s digital age, data is everywhere, and businesses are generating more of it than ever before. Therefore, it’s crucial you know how to handle it.

Businesses collect large volumes of data every day, and it’s this data which can be used to develop insights and analyze business operations. For a small business, however, the sheer magnitude of the data involved can be overwhelming. But it doesn’t have to be like this. Instead, you can manage big data simply and effectively, an approach which will help boost your efficiency and competitiveness. And Ophtek is here to show you how.

Demystifying Big Data

Big data encompasses all the data your business logs, processes and handles through the course of its daily operations. So, for example, sales records, customer details, social media interactions, and quotations can all be considered part of big data. The three main aspects of big data include the amount of data generated, the speed at which this is produced and processed, and all the different types of data which comprise your unique collection of big data.

How Can Big Data Help Small Businesses?

The main impact of harvesting big data is that it allows you to uncover patterns and trends within your business activities. In the past, this data would likely have been kept of paper records, and analyzing this would have been a painstaking process. Luckily, advances in technology mean this data can now be stored and automatically analyzed with much more ease. By analyzing big data, you can reap the following benefits:

How Should You Use Big Data to Succeed?

If you want to leverage big data to make a noticeable impact on your business, make sure you practice the following:

  • Start with Clear Goals: it’s crucial you identify what you want to achieve with your data. You may, for example, want to improve customer satisfaction, or you could be looking to maximize your sales. Either way, by setting specific goals, you’ll be able to identify what you need from your data.
  • Use Accessible Tools: analyzing big data can be complex, but it doesn’t have to be difficult. By utilizing tools such as Google Analytics, for website data, or HubSpot, for customer experience data, you can easily gain access to almost endless insights relating to your data.
  • Act on Insights: the most important process in analyzing big data is making sure you follow through on the results. These changes won’t implement themselves, it’s down to you and your team to take these insights and put them into action. And always monitor the impact of these changes, this will reveal whether they’re successful or require further tinkering.

A North Korean hacking group has targeted two South Korean cryptocurrency companies with a new strain of malware dubbed Durian.

The relationship between North and South Korea has always been troubled, and this latest cyber-attack will do little to resolve these tensions. The attack itself uses a previously unseen malware variant known as Durian, which is coded in the Golang programming language. Both attacks occurred in the second half of 2023, with Kaspersky recently announcing them in their Q1 APT trends report.

While you may not run a cryptocurrency firm, or be a target of North Korea, it’s important to understand contemporary threats, so we’re going to look at Durian.

How Does Durian Work?

The exact attack method which Durian uses is currently unknown, but it appears to target software which is exclusively used in South Korea. It’s likely, therefore, that a vulnerability has been discovered, although no specific vulnerability has been identified yet. Regardless of the entry method, what is known is that Durian sets up backdoor functionality. This allows the threat actor to download further files, harvest data and files to external servers, and execute commands on the compromised servers.

Once Durian has a foothold within a target’s system, it starts downloading further malware such as Appleseed and LazyLoad, alongside genuine apps such as Chrome Remote Desktop. This makes Durian a particularly persistent threat and makes it a difficult piece of malware to combat.

It’s believed that the threat actor behind Durian is Kimsuky, a North Korean group who has been active since 2012. Kimsuky has been busy in recent times and appear focused on stealing data on behalf on North Korea. Notably, the usage of LazyLoad indicates that Kimsuky may also be partnering with another North Korean group known as Lazarus. LazyLoad has previously been deployed by Andariel, a splinter group with connections to the Lazarus Group.

Staying One Step Ahead of Durian

A specific fix against Durian hasn’t been announced, but this doesn’t mean your defenses are under immediate threat. Instead, by following the basic principles of cybersecurity, you can keep your IT infrastructure safe:

  • Always Install Updates: it’s suspected Durian is targeting specific software to establish itself on targeted systems, and this indicates that a vulnerability is being exploited with this software. Therefore, this acts as a worthy reminder on the importance of installing updates promptly. These updates can instantly plug security holes and keep your IT systems secure.
  • Be Aware of Spear-Phishing: Kimsuky is known for employing spear-phishing techniques so it’s vital your employees are educated on this threat. Typically, spear-phishing targets specific individuals within a company and attempts to deceive them into providing confidential information or direct access to internal systems.
  • Use Multi-Factor Authentication: if you want to add extra locks to your IT systems, then multi-factor authentication is the way forwards. Password breaches are common, but the use of multi-factor authentication minimizes the risk this poses. After entering a password, a unique code will be sent via SMS or through an authentication app which only the end user will have access to. Without this code, a threat actor will be unable to get any further with your password.
