A new malware threat has been discovered which uses the public excitement around the Webb telescope to deliver a phishing scam.

The first image to be released by the Webb telescope project was entitled SMACS 0723, and its new, stunning view of the galaxy created headlines around the world. However, it’s this level of interest which has led to hackers using it as bait. The image is used as part of an email phishing scam and, unfortunately, fails to highlight the wonders of space. Instead, it compromises a PC and leaves it at risk of further attacks.

Phishing scams are a contemporary irritant in the IT security world, so we’re going to delve deeper into this one and see what we can do to help protect your PC.

The Threat from Outer Space

This latest strain of malware has been given the rather complex name of GO#WEBBFUSCATOR but the way in which it operates is simple. Security experts Securonix have discovered a phishing email – described as one promoting satellite service plans – which contains an infected Microsoft Office document. If this document is downloaded and opened, the malware will – if Word macros are enabled – begin to release its payload.

The malware begins by downloading the SMACS 0723 image, but this image is far from innocent as it contains hidden Base64 code. With this code activated, the infected PC is then systematically tested for vulnerabilities and weaknesses. Once these have been detected and analyzed, the hackers begin a campaign of exploitation to take control of the PC. It’s also interesting to note that the computer language behind this malicious code is constructed from Go, a cross-platform language which highlights the scope of the threat actors behind GO#WEBBFUSCATOR.

Staying Safe on Planet Earth

The number of vulnerabilities this malware targets, along with its deceptive approach, make it a powerful weapon for hackers. Therefore, protecting yourself against its dangers is paramount and you must make sure you:

  • Monitor network activity: once malware such as GO#WEBBFUSCATOR has made its way onto your PC, it’s likely that you will notice a surge in unusual activity on your network e.g. increased traffic and downloads. And this is likely to be one of the only signs you receive, so it pays to keep a close eye on any spikes in network activity.

Using a new remote access trojan, threat actors behind the Cuba ransomware have amassed ransom payments estimated to be close to $44 million.

Over the past five years, countless headlines have been generated by the damage caused by ransomware attacks. Not only do they compromise access to your organization’s data, but they also have the potential to inflict painful financial damage. To make matters worse, these attacks are evolving to become more powerful and harder to prevent. In fact, on many occasions (and as we’ll see with the Cuba ransomware) these evolutions will take place over a matter of months.

Ransomware, therefore, is a very real threat to your organization’s IT network, so it’s important that you understand exactly how the Cuba ransomware operates.

What is the Cuba Ransomware?

Cuba was first detected in late 2019 before disappearing from the frontline and returning two years later in November 2021. Evidence of the Cuba ransomware has been detected in around 60 ransomware attacks, with 40 of these victims revealed to be US-based. Cuba is delivered to PCs through the Hancitor loader, a type of malware which is used to download and execute additional malware e.g. remote access trojans. Hancitor makes its way onto PCs through a variety of means such as phishing emails, stolen login credentials and software vulnerabilities.

Since Cuba first emerged onto the digital landscape, it has undergone a series of significant changes. The most notable changes have seen it terminating more processes before it locks files, widening the range of file types it encrypts and, believe it or not, enhancing its support options for victims wanting to pay. Cuba has also been observed operating a backdoor trojan called ROMCOM RAT, a piece of malware which deletes files and logs data to a remote server.

Protecting Yourself Against the Cuba Ransomware

With Cuba collecting ransom payments of over $40 million, it’s clear to see Cuba is a dangerously effective threat. It’s also important to point out there is currently no known decryption tool available to combat Cuba’s encryption methods. Accordingly, you need to be on your guard against this threat and any similar attacks. Therefore, make sure you practice the following:

  • Install updates: Cuba has the power to exploit software vulnerabilities to gain unauthorized access to computer networks, so it’s crucial that you always install updates as soon as possible. The install process for updates can feel time consuming, but when you have the option to automate these installations, there’s no reason this shouldn’t take place.

The Hello XD ransomware was first spotted in the digital wild back in November 2021, but recent research indicates that it’s becoming more virulent.

There’s no such as ‘good’ ransomware, but it’s not unreasonable to describe Hello XD as ‘disastrous’ due to its enhanced capabilities. Whereas, previously, Hello XD focused its efforts on the standard ransomware practice of encrypting files, its evolved form now includes a backdoor feature. This enhanced functionality allows the transfer of data from infected PCs to external sources. Combined with its ransomware feature, this new form of Hello XD represents a huge security risk.

Ransomware is a highly problematic attack, and it’s one which your organization needs to avoid at all costs. Hello XD is the latest in a long line of ransomware attacks and, as ever, it could save you a fortune by understanding how it operates.

Hello XD Steps Up Its Game

Spread through various phishing techniques, Hello XD operates in the following manner once it arrives on a PC:

  • Hello XD’s first step is to disable shadow copy capabilities, this means that system snapshots cannot be saved or accessed. System recovery, therefore, can’t be used to counter the impact of Hello XD.
  • The infected system’s hard drive is then encrypted by Hello XD, all files are encrypted with a .hello extension and rendered inaccessible.

Clearly, Hello XD packs a powerful punch and has the capability to bring your organizations IT operations to a halt. It is believed that Hello XD has been designed by X4K, a Russian-speaking hacker who has been advertising his wares on various hacking forums. It’s also likely that X4K will enhance Hello XD’s capabilities even further for future attacks, so it’s crucial you remain alert.

How Do You Say Goodbye to Hello XD?

The best way to avoid falling victim to Hello XD is by practicing the following:

  • Understand phishing techniques: Hello XD, and many other forms of ransomware, use phishing strategies such as mass emails to snare their victims. Emails, for example, which instill a sense of urgency over financial matters can be used to encourage users to open malicious attachments. However, if your employees understand the tell-tale signs of social engineering, they will be better placed to avoid falling victim to phishing attacks.

Anti-malware tools provide a firm level of defense against hackers, but what happens when the malware can bypass detection tools?

Around 300,000 new pieces of malware are created daily, so it’s important that we can protect ourselves against this constant threat. Anti-malware tools such as Kaspersky and even in-built Windows security systems are crucial for providing this protection. Accordingly, you should find that your systems remain protected for most of the time. However, hackers are industrious individuals and are constantly looking to evolve their techniques. As a result of this ongoing adaptation, it appears that hackers have found a way around current detection methods.

The threat comes in the form of the OpenSUpdater and is one that you need to take seriously.

What is OpenSUpdater?

Digital signatures are used online to demonstrate that code is legitimate and accepted by Windows security checks. They are an important part of online security, but this has made them a viable target for hackers. In the case of OpenSUpdater, their online code samples are carrying manipulated security certificates which, despite these manipulations, are passed as authentic by Windows. More importantly, security tools which use OpenSSL decoding are unable to detect these malicious changes.

OpenSUpdater is free to bypass security measures and avoid being labelled as malware which is quarantined and deleted. The malware’s main method of attack is through riskware campaigns. This involves injecting malicious ads into the browsers of those infected and downloading further malware. The majority of targets so far have been found in the US and the malware typically bundled in with illegal downloads such as cracked software.

How Can You Protect Against OpenSUpdater?

This latest malware threat was detected by Google’s security researchers and has since been reported to Microsoft. A specific fix has not been announced yet, but hopefully something will be implemented shortly. In the meantime, however, it’s vital that you take steps to protect yourself. In particular, make sure you focus on the following:

  • Educate on Phishing Techniques: Phishing is a dangerous hacking technique which uses email to push social engineering attacks. By instilling a threat of urgency to act upon an email’s call to action – such as ‘click here to download a vital security tool’ – hackers are able to deceive victims into downloading all kinds of malware. Thankfully, through continued training, your employees should be able to recognize phishing emails quickly and hit the delete button even quicker.

Beware of Online Tax Scams

Jan 2021

Many of us will have started preparing our tax returns and hackers are well aware of this. Therefore, it pays to be aware of the numerous online tax scams.

Nobody likes completing tax returns due to the vast amount of data involved. However, they’re essential for organizations to remain operating. And that’s why we spend hours and hours collecting receipts and details for transactions; this is where all the data builds up. Hackers, of course, like nothing more than getting their hands on huge amounts of data. This data can be used for both financial gain and damaging an organization. Accordingly, tax season is their hunting season.

Tax Scams to Look Out For

Countless tax scams are currently circulating in the digital wild, but these are the most common ones you will encounter:

  • Automatic Tax Payment Deduction: A number of emails have been discovered which claim to originate from the Income Tax Department. These emails falsely claim, in order to generate anxiety, that a tax payment has automatically been deducted from their bank account. An attachment is included which masquerades as a receipt for this transaction. Hackers hope that the recipient’s anxiety and confusion will cause them to open this receipt. Unfortunately, contained within this ‘receipt’ is a slice of malware named W32.Golroted. 
  • Fake Government Websites: A popular method for scamming victims out of money is by designing Government websites which look authentic, but are fake. Using information which has usually been stolen through malicious files or social engineering, these fake websites inform victims that they have received a tax fine. The only way to pay this fine is by wiring payment or purchasing general purchase reloadable cards. However, there is no fine to pay and all the victim will be doing is bankrolling the hackers. 
  • IRS Tax Return is Locked: The last few years have seen the emergence of a phishing email which claims that access to the recipient’s tax return has been restricted. The email is designed to look as though it has been sent by the IRS or, sometimes, the manufactures of the popular TurboTax software. The truth is that the email is fake and has been sent by hackers. The email will urge recipients to click on a link which will take them to a malicious website where their personal information will be stolen.

Staying Safe During the Tax Season

Despite the number of online tax scams it’s easy to stay safe during the tax season. All you have to do is follow these best practices:

  • Remember that the IRS will never contact you by email to discuss the nature of your tax return or your personal details.
  • Verify the true identity of any suspicious links by hovering your mouse cursor over the link. A popup will then display where the link will send you.
  • Never send personal documents to unsolicited email requests as it is likely that a hacker is trying to harvest your details
  • Emails that claim to be from official organizations, but do not use your name are to be treated as highly suspicious and should be deleted.
