PCs have transformed the way we do business, but it’s important that we constantly move forward and avoid becoming complacent. There are always better ways to do things, more effective procedures and, often, easier solutions to our problems. And implementing these into your organization’s day-to-day operations will always pay dividends in terms of productivity and competitiveness. T he best way to achieve this is by adopting the most essential tools for business PCs.

The Most Essential Tools You Need for Business PCs

Take a look at any software catalogue and you’re going to struggle to know where to start. The sheer range of available apps and tools is endless. But we’re going to give you a helping hand. So, if you want to raise your business game and get the most out of your PCs, make sure you work with the following tools:

Communication: strong communication and collaboration tools have become crucial in the last decade, most noticeably during and after the Covid-19 pandemic. Thankfully, modern software development allows seamless teamwork to be a reality no matter how scattered your team are. Tools like Slack, Microsoft Teams, or Google Workspace provide real-time messaging, video conferencing and file sharing capabilities. This means your teams can communicate and work together effectively.
Productivity suites: every business needs to arm themselves with a fully functioning productivity suite. The most common examples of these tools are Microsoft Office 365 and Google Workspace. With these suites integrated into your PCs, your employees will be able to access a wide range of applications such as word processing, spreadsheets, presentations, and email.

Routers are an essential part of any modern business which uses IT systems. But what happens when you’re working with a compromised router?

Routers are devices which help to connect different networks together. They receive data packets from one network, analyze the destination address, and then forward the data to the relevant destination network. Essentially, a router is used to facilitate communication between different devices and networks. The internet, of course, is crucial to directing this data and this makes routers highly attractive targets for threat actors.

Therefore, the discovery of a vulnerability within a router presents a significant threat to your cybersecurity. But, when there are five vulnerabilities within the same router, you have a disaster on your hands.

A Quick Guide to the 5 Vulnerabilities

Netgear has had to concede that their Netgear RAX30 routers have been exposed as lacking that seal of quality when it comes to security. A router, after all, is your gateway to the internet, the place where all your communication begins. If this is compromised, then a whole world of trouble is just waiting to take advantage. The five vulnerabilities picked up for the Netgear RAX30 routers are:

CVE-2023-27357: this security flaw allows external attackers to identify and record sensitive information passing through Netgear RAX30 routers.
CVE-2023-27368: an attacker can use this vulnerability to execute malicious code on the compromised routers. And, as user data is not being correctly validated by the Netgear RAX30 router, threat actors are able to avoid having to authenticate their access.
CVE-2023-27369: much like the previous vulnerability, this specific flaw allows attackers to run malicious code, or indeed any code they like, on affected systems.
CVE-2023-27370: unfortunately, for users of the Netgear RAX30 router, sensitive configuration data is stored in plaintext on the router. This allows attackers, who can easily bypass the authentication mechanisms, to steal system credentials with ease.
CVE-2023-27367: the final vulnerability known to be affecting the Netgear RAX30 router is, again, one which allows attackers to exploit it and run malicious code through it.

With all five vulnerabilities scoring highly on the Common Vulnerability Scoring System (CVSS) – with three of them gaining a CVSS of 8 or above – Netgear has a big problem on their hands.

How Do You Safely Secure Your Router?

Netgear has been quick to address the five vulnerabilities, with an updated firmware version released on April 7, 2023. However, it’s important that you always make sure your router is as secure as possible. And you can do that by putting the following into action:

Always change default login credentials: some routers are shipped with default login credentials, but this makes them incredibly easy to guess. In fact, many lists of default credentials can quickly be found online. Accordingly, make sure you always change your router’s login credentials before going online with it.
Enable WPA2 encryption: Another way to protect your router is to enable WPA2 encryption. This will secure the wireless network and prevent unauthorized access. Make sure to use a strong encryption key and avoid using common words or phrases that can be easily guessed.

Always update your router: regular firmware updates and patches ensure that your router remains as safe as possible. However, it’s crucial that you install these as soon as possible. Sometimes it can be time consuming to go through the update process, but it can save you major headaches further down the line.

Jul 2023

The launch of ChatGPT and its accompanying headlines have been heard around the world. And threat actors are leveraging this interest to launch new attacks.

You don’t have to look hard to find a headline relating to ChatGPT, the latest and most intriguing AI service to be released to the public. Everyone has been talking about it and, of course, this also includes hackers. After all, anything which proves popular – such as social media and cryptocurrency – quickly becomes an attractive method of delivering malware. Now, while you and your business may not use ChatGPT daily, this latest campaign utilizes a few attack strategies you need to be aware of.

How Has ChatGPT Got Caught Up in Malware?

The massive interest generated by ChatGPT means that AI related apps are at the forefront of most internet users’ thoughts. As a result, threat actors have decided to turn this interest to their benefit with their most favored technique: deception. The attacks, which were discovered by Meta, the owners of Facebook, have involved 10 different malware families and, on Meta’s platforms alone, 1,000 malicious links relating to ChatGPT.

Two of the most notable strains detected, which appear to have originated from Vietnam hacking groups, are NodeStealer and DuckTail. NodeStealer is a JavaScript-based piece of malware which is used to steal cookies and login credentials. DuckTail, meanwhile, not only steals cookies, but also focuses on hijacking Facebook business accounts to access lucrative ad accounts. Both of these malware strains are typically spread and activated via infected files or links to malicious websites.

How Do You Stay Ahead of AI Malware?

The official and genuine ChatGPT site has already been used by threat actors to develop new malware, so there is already concern about how it can be compromised. And this latest attack, while not directly involving the app, certainly adds fuel to the fire. Deception, of course, is nothing new in the world of hacking. But the number of people who fall for the duplicitous schemes of hackers is astronomical. Therefore, you need to remain on your guard by following these best practices:

Educate yourself: Phishing scams and techniques are constantly evolving, so it’s important to understand the key basics of these attacks. Emails, for example, which include urgent or threatening language, requests for personal information, and suspicious URLs should never be trusted. Regularly educating yourself on these scams can help you avoid falling victim to malicious links and keep your online accounts secure.

Only download from safe sources: downloading files from unknown sources can put your PC at risk of malware, viruses, and other types of cyberattacks. Accordingly, only download files from reputable websites and avoid clicking on links from unknown sources. Also, emails which contain attachments, especially those from unknown senders, should immediately be quarantined. These precautions will help protect your PC and your organization’s wider IT infrastructure.

Use two-factor authentication: many of the malware strains identified in the latest round of ChatGPT-related attacks involve stealing credentials. Therefore, there’s never been a better time to implement a further layer of security in the form of two-factor authentication. While it won’t necessarily protect against session hijacks, two-factor authentication will significantly reduce the risk of unauthorized access to your accounts.

Bumblebee Malware Gives a Nasty Sting Through Google Ads

Jun 2023

It’s difficult to avoid online ads these days. This makes them the perfect target for hackers. And this is what they have done with the Bumblebee malware.

It’s estimated that the average American is exposed to between 4,000 to 10,000 online ads a day. And each one of these ads has the potential to carry malware. Therefore, it’s not surprising that threat actors have started exploiting them. This recent attack, however, has also employed SEO poisoning in its campaign – this is a method by which hackers create malicious websites and tempt visitors there with high-demand keywords.

Bumblebee, then, is a credible threat to your organization and its IT systems. Consequently, it’s important that you know how it operates and, most importantly, how to avoid it.

What Do You Need to Know about Bumblebee?

First discovered in April 2022, the Bumblebee malware is classed as a ‘malware loader’ variant. This means that it is used to connect a remote attacker directly with the infected system. It’s believed that Bumblebee comes from the same hacking group behind BazarLoader. Bumblebee, however, is more powerful and is backed by enhanced stealth capabilities. So, not only is it capable of causing greater damage, it’s also harder to detect. This, as I’m sure you’ll agree, is the last thing any PC owner wants to hear.

The most common approach for Bumblebee is to use Google Ads to lay bait for unsuspecting PC owners. For example, a Google Ad promising a free SQL to NoSQL guide was used to redirect those who clicked it to a fake download page. We say “a fake download page” but it did, in fact, take people to a page where a download occurred. Instead of a free guide, though, it instead downloaded Bumblebee. This malware was then opened and, to reduce detection, loaded Bumblebee into the infected system’s memory.

Typically, Bumblebee has been targeting businesses rather than consumers. Ransomware, therefore, has been at the front of the threat actors’ operations. But this is achieved through highly detailed planning. Upon the initial infection, Bumblebee quickly downloads a series of malicious tools such as remote access services, network scanning apps and keystroke loggers. This strategy allows the attackers to identify weak spots and deploy ransomware where it will be most effective.

How Do You Beat Bumblebee?

All business owners can agree that ransomware is a headache they can do without. So, how do you keep your systems safe from the Bumblebee attack? Well, you may be surprised that the following tips make it very easy:

Use an ad-blocker: if you can block malicious ads, you’re blocking their opportunity to cause damage. The simplest way to achieve this is by installing an ad-blocker. These tools will minimize the number of adverts which can be shown and, instantly, reduce your risk of falling for a malicious ad.

Keep your software up to date: malicious ads often take advantage of vulnerabilities in outdated software. By keeping your web browser, operating system, and other software up to date, you can reduce your risk of falling victim to malvertising attacks.

Educate your staff on malicious ads: it’s very easy for busy employees to experience a momentary distraction, and this is when they are most likely to click on a malicious ad. However, with regular training, which includes examples, you can prime your staff to dismiss malicious ads the moment they see them.

RapperBot Malware Develops New Distribution Tricks

IoT Attacks, malware, Ophtek, RapperBot, Security, strong passwords, UpdatesIoT Attacks, malware, Ophtek, RapperBot, security, strong passwords, updatesOphtek, LLC

Jun 2023

Malware constantly evolves, and that’s why it’s a constant thorn in the side of PC users. The ever-changing RapperBot malware is a perfect example of this.

If malware was boring and lacked innovation, it wouldn’t last very long or infect many computers. It would make our lives a lot easier, but it would defeat the main objective of malware. And that is to cause chaos. Repeatedly. Therefore, malware developers are keen to extend the lifespan of their creations. This is why malware is regularly developed, to keep one step ahead. It’s the digital example of a game of cat and mouse. But the good news is that you don’t have to be the mouse.

The Lowdown on RapperBot and Its Evolution

First discovered in 2022, RapperBot started its malware career in the Internet of Things (IoT) niche. Most notably, RapperBot was observed to be using parts of the Mirai botnet code. However, RapperBot was much more than just another take on Mirai. It was much more sophisticated. Not only had its remote access capabilities been upgraded, but it could now also brute force SSH servers – these allow two PCs to communicate with each other.

This evolution has continued at pace, with security experts Fortinet and Kaspersky detecting the following changes:

After infection, further code was added into RapperBot by the developers to avoid detection. A situation which persisted even after rebooting. A remote binary downloader was later added to allow self-propagation of the malware.

The self-propagation capabilities of RapperBot were later changed to allow the malware to gain constant remote access to SSH servers which had been brute forced.

Finally, RapperBot moved its aim away from SSH servers and targeted telnet servers. Cleverly, RapperBot sidestepped the traditional technique of using huge data lists and, instead, monitored telnet prompts to determine the target device. This allowed the threat actors to identify IoT devices and quickly try their default credentials.

The Best Tips for Tackling RapperBot

IoT devices are plentiful in the modern age, and we certainly couldn’t be without them. Accordingly, we need to protect them from threats such as RapperBot and BotenaGo. You can do this by following these best tips:

Keep devices up to date: it’s crucial that you regularly update the firmware and software which supports your IoT devices. Few, if any, pieces of hardware reach consumers without some form of security flaw present. Once these flaws are detected, the manufacturer will usually release a patch or update to remove this vulnerability. Therefore, you need to install these as soon as possible, a strategy which is made easy by allowing automatic updates.

Change default passwords: Many IoT devices come with default usernames and passwords, these are often the same across every single version of that device. As such, they represent an incredible risk. This means you need to change these default credentials to strong, unique usernames and passwords before they are connected to your IT infrastructure. Additionally, enable two-factor authentication, wherever possible, to add an extra layer of security.

Network segmentation: ideally, separate networks should be created to house your IoT devices and isolate them from your core network. As IoT devices carry a certain amount of risk, it makes sense to keep them away from the majority of your IT infrastructure. This ensures that, if an IoT device does become infected, the malware can only spread so far.
