Every business relies on digital documents, but the threat of data breaches and cyberattacks mean these documents must be correctly secured.

There are many types of documents a business uses daily such as Word, Excel, PDF, and digital images. All of these can contain sensitive information, and it’s no surprise threat actors want to get their hands on them. Not only can a threat actor use these to compromise other accounts, but they can cause real financial damage with them. Accordingly, it makes sense to secure your organization’s digital documents to keep them safe.

Securing Your Digital Documents

Your business may contain numerous files in different locations, but the good news is that securing all of them is straightforward. Just make sure you follow these best practices:

  • Password Protection: the simplest way to secure your digital documents is by implementing password protection. A common security measure for decades, passwords put a major barrier in the way of unauthorized access. Not all files can be password protected, but common files such as Microsoft 365 documents and Adobe PDF documents can.
  • Use Strong Passwords: central to good password protection is strong passwords. Never use passwords which are easy to guess e.g. using “password” or “admin”. Instead, always use passwords which combine upper and lower case characters with numbers and symbols. It’s also recommended that passwords are longer than 8 characters and different passwords should be used for different documents.
  • Restrict Access: it’s important to remember not every employee needs access to every single file within your organization. Your marketing team, for example, doesn’t need access to your finance team’s documents and vice-versa. Accordingly, you need to restrict access to only those who need it. The best way to achieve this is by setting up ‘restricted’ drives for each team to store their department-specific documents.
  • Use Windows Encryption: compromised devices present a goldmine of data for threat actors, but it’s possible to avoid this disaster by encrypting your devices. Yes, if you’re running Windows 10/11 Pro or Enterprise versions, it’s possible to encrypt data and provide access only to those with authorization. This is easy to put in place and, if Windows encryption is not available on the device, you may still be able to use BitLocker encryption to encrypt it.
  • Always Create Backups: in the event of a ransomware attack, your organization could find all of its documents encrypted and inaccessible. This is why creating backups is the surest way to enhance the security of your digital documents. The preferred method for executing this is with the 3-2-1 backup method, as this provides you with multiple copies in different locations. Complete loss of your data is minimized and there’s no need to pay any ransom fees.

Final Thoughts

All it takes is for a single file to be compromised by threat actors to cause major damage, so it’s crucial that you prioritize securing your digital documents. Putting the suggestions above into practice is relatively easy, and it ensures your data remains safe. So, don’t delay, secure your digital documents today and benefit from the peace of mind it provides.

Malware and flies share one thing in common: they’re pesky. However, while flies help the ecosystem, the Striped Fly malware is nothing but trouble. 

Striped Fly has recently hit the headlines, but Kaspersky has revealed they’ve found evidence of its malicious activity dating back to 2017. Unfortunately, no one had been aware of its true identity until now. This means Striped Fly has enjoyed a five-year campaign where not even a single security researcher knew of its existence. And Kaspersky estimate that this invisibility has allowed it to infect over one million Windows and Linux hosts.  

In 2017, Striped Fly was mistakenly labelled as a cryptocurrency miner, falling under the Monero trojan family. Subsequent findings, however, have revealed that Striped Fly is much more sophisticated. 

What is Striped Fly?

Striped Fly’s exact mechanism is not fully understood at present, but researchers believe they know how it operates. It’s suspected that the threat actors exploited an EternalBlue SMBv1 exploit to gain a foothold in internet facing PCs. After discovering evidence of Striped Fly within the WININIT.exe application – used to help load subsystems within Windows – Kaspersky determined that it then downloads further files. 

These files typically come from online software depositories such as GitHub and BitBucket. These are used to build the final Striped Fly payload. Cleverly, Striped Fly comes with Tor network capabilities to encrypt its communications. Tor, of course, is an internet router service used to encrypt data transferred over its network. And this is part of the reason why Striped Fly remained hidden for so long. 

The main talking point about Striped Fly is its sophistication and wide range of functions. Striped Fly is capable of harvesting login credentials, taking unauthorized screenshots of infected devices, stealing Wi-Fi network configuration details, transferring files to remote sources, and recording microphone output. Clearly, it poses a significant threat to all PC users. 

Swatting Striped Fly Away 

Striped Fly’s half-decade long campaign has proved to be highly successful. Accordingly, your organization needs to be on its guard against Striped Fly and any similar threats. Kaspersky hasn’t revealed a specific fix for Striped Fly but, as ever, vigilance and good security practices are key. So, make sure the following is part of your established cybersecurity strategy:

Healthcare organizations across the United States and Europe have recently found themselves targeted by Lazarus, the North Korean hacking group. 

Lazarus, who are believed to have ties to the North Korean government, are well known in the world of cybersecurity. In 2022, Lazarus were rumored to have stolen a total of $1.7 billion worth of cryptocurrency across the year. So, yes, Lazarus is a force to be reckoned with. As their latest attack targets organizations rich in sensitive data, it’s important to understand their methods and determine the lessons that can be learned. 

What Is Lazarus’ Latest Campaign? 

At the heart of this new attack by Lazarus is the ManageEngine ServiceDesk. This management suite is used to help organizations manage their entire IT infrastructure. From networks and servers through to mobile devices and applications, ManageEngine helps make life easier for IT teams. It’s a highly popular management suite, with numerous Fortune 100 businesses implementing it. For healthcare organizations, it’s a crucial service which allows them to stay productive and support their IT systems. 

However, as with all, applications, ManageEngine is not 100% secure. The CVE-2022-47966 vulnerability, which was discovered in January 2023, was first exploited by threat actors in February of the same year. This vulnerability allowed the deployment of QuiteRAT, a new and complex brand of malware. QuiteRAT let the threat actors steal data relating to the compromised device and, cleverly, allowed QuiteRAT to “sleep” in order to appear dormant and stay off the radars of security professionals. 

Another part of the attack also involves a new strain of malware dubbed CollectionRAT, which has the ability to perform typical remote access trojan tasks such as executing commands on a compromised system. As with previous campaigns, this latest strike utilizes many of the trademark Lazarus tactics and innovations. For example, by using open-source tools to create CollectionRAT, the threat actors are able to launch their attacks more quickly and without raising the alarm immediately. 

How Do You Protect Your Organization from Lazarus?

Naturally, the most obvious way to protect your IT infrastructure from Lazarus is to be prompt with installing software patches. Lazarus appears to have infiltrated these healthcare organizations due to a known vulnerability, so patching any holes within your IT systems is essential. Luckily, many updates, such as Windows, can be set to automatic and ensures that your applications are as secure as they can be. 

Hacking groups, however, don’t rely solely on vulnerabilities to launch their attacks. In fact, they will deploy almost every technique you can think of to launch an attack. The best practices to stay safe from these are:

The HiatusRAT malware has re-emerged from its slumber to prove how resilient it is by targeting multiple organizations in Taiwan and the US. 

As with most malware which is deemed successful in terms of its longevity, the threat actors launching HiatusRAT have ensured that it’s more powerful than ever. And, to strengthen its attack, they have redesigned it to escape detection. So far, the majority of the organizations targeted by this latest version of HiatusRAT have been based in Taiwan, but at least one US-based military system has also been attacked. And, with HiatusRAT seemingly operating at full throttle, it’s likely to spread even further. 

Due to the potential danger contained within HiatusRAT, we’re going to take you through how it operates and how you can protect your organization. 

The Lowdown on the Latest HiatusRAT Campaign 

HiatusRAT was first detected back in March 2023, when it was discovered infecting the routers of various organizations in Europe and North and South America. This attack involved stealing data by hijacking email channels as well as installing a remote-access Trojan (RAT) on infected routers. It was an attack which led to significant data loss, but the malware’s activity soon dropped off. However, during this downtime, HiatusRAT has been refined and reconfigured. 

Again, HiatusRAT appears to be targeting routers and similar networking devices. By redesigning HiatusRAT to target ARM and Intel hardware, the threat actors – who are currently unknown – have managed to enhance the potency of their malware. Operating with two types of servers – Tier 1 and Tier 2 – they have been able to use multiple IP addresses to transmit data to remote sources. As the attack has targeted at least one military system, it’s suspected that there may be a nation-state involved with the attack. However, as of now, security researchers have been unable to pinpoint the true motives outside of data theft. 

Protecting Your Organization from HiatusRAT

You may not run an organization in the military industry, but RAT-based malware doesn’t tend to discriminate. Therefore, you need to be on your guard against HiatusRAT and other similar attacks. Remaining vigilant is crucial, and you can strengthen this vigilance by practicing the following:

As the popularity of AI apps soars, the latest being Google’s Bard, it’s becoming clearer that threat actors are taking advantage of this popularity.

The latest attack to be launched revolves around BundleBot, a new brand of malware which is as stealthy as it is dangerous. Bundlebot is typically found lurking within Facebook ads that promise to take you to websites containing AI utilities and games. These websites, however, are malicious. Users report that these malicious websites are similar, in terms of design, to Bard, but their main objective is to encourage users to download malicious files, most typically hosted on an external storage site such as Dropbox.

As we become more and more interested in AI, it’s important that we remain on guard against threats such as BundleBox, so let’s take a more in-depth look at what it is.

The Lowdown on BundleBox

Once the malicious file – an RAR archive file often named Google_AI.rar – is downloaded and executed, the BundleBox campaign begins. Within this archive file, is an executable file called GoogleAI.exe which, once activated, retrieves a ZIP file (ADSNEW-1.0.0.3.zip). Once opened, this ZIP file contains a further application by the name of RiotClientServices.exe. This executable is used to fully launch, through the use of a .dll file, the BundleBox attack.

Thanks to junk code being built into Bundlebox’s design, it is able to operate stealthily and away from the attentions of anti-malware software. While it remains hidden, BundleBox utilizes a ‘command and control’ function to steal sensitive data and transmit it to a remote location. The perpetrators behind BundleBox, currently, remain a mystery, but it’s believed they are from Vietnam, due to similar Vietnamese-based attacks being launched through Facebook in recent months.

Staying Safe from BundleBox and Similar Threats

There is no definitive solution to a BundleBox infection at present, but there are plenty of ways you can protect your PCs from falling victim. Make sure that your organization enforces the following:
