What is Buhti ransomware?

Buhti ransomware is an advanced form of malware that has the ability to encrypt your files, making them inaccessible.

Once your data is encrypted, the attackers demand a ransom, often in cryptocurrency, for the decryption key.

This new variant was identified in February 2023 by Unit 42, which informed users via its Twitter profile.

What is Buhti ransomware HelpRansomware

As you can read, this type of ransomware prefers attacks against the Linux and Windows operating systems.

Moreover, experts have presented the Buhti ransomware as a particularly insidious form of malicious software, as it poses a serious threat to companies, professionals and individuals.

Once opened, the ransomware activates by encrypting files and rendering them unusable.

How does it work?

As written in the HivePro report, the Blacktail group responsible for the ransomware demonstrates a quick response to exploit vulnerabilities.

Their attacks specifically targeted a recently discovered vulnerability in PaperCut NG and MF (CVE-2023-27350).

This ransomware is unique in three ways:

  • Instead of developing its own malicious payload, Buhti chose to use variants of the leaked LockBit and Babuk ransomware families to target both Windows and Linux systems;
  • Buhti created a custom data exfiltration tool coded in Golang;
  • Hackers run ransomware remotely and use exploits to steal data and distribute the payload to computers on the same network.

Many antivirus and firewall software have difficulty detecting it because of its ability to disguise itself as a legitimate application or use rootkit techniques to hide in the operating system.

This makes it extremely difficult to detect and remove, increasing the risk and potential consequences of infection.

Often, the victim does not realize they have been attacked until the ransom demand appears on their screen, which looks like the image below.

Key features of Buhti ransomware

Buhti ransomware is known for a number of characteristics that make it a particularly fearsome adversary in the cybercrime landscape, such as:

  • Advanced encryption: its algorithms are designed to be resistant to decryption efforts, making it nearly impossible for victims to access their data without the specific key provided by the attackers;
  • Cryptocurrency payment: this payment method provides a level of anonymity that makes it extremely difficult for authorities to trace attackers;
  • Security evasion: Buhti uses masquerading and rootkit techniques to hide in the operating system, making it difficult for antivirus software to detect.

This means that even if you have the latest anti ransomware, there is a chance that Buhti could slip through the net;

  • Speed of action: Buhti executes a rapid, automated attack that can cripple an entire organization in minutes, leaving no time to respond.

As noted in the Sophos report, in the first half of 2023, the average dwell time for ransomware incidents dropped dramatically from 9 days to 5 days;

Key features of Buhti ransomware HelpRansomware
  • Selective targeting: while many ransomware take a blanket approach, Buhti is known to pick and choose its targets, focusing its efforts on companies or individuals that are more likely to pay the ransom.

For all of these reasons, if you suspect or experience a Buhti ransomware attack, it is important to act quickly and contact a specialized company like HelpRansomware for an immediate assessment and action plan.

Consequences of Buhti ransomware

The consequences of a Buhti ransomware attack go far beyond simply losing access to data.

Here are some of the more serious consequences:

  • Operational disruption: from accessing customer databases to managing human resources and finances, the loss of critical data can cripple a business;
  • Reputational damage: ransomware attacks can lead to a loss of trust among customers and business partners, which can have a long-term impact on a corporate reputation;
  • Financial costs: in addition to the ransom demanded, which can run into the thousands of dollars, there are costs associated with recovering from the attack and the loss of business during the downtime.

Consider that, according to IBM, the average cost of a data breach in 2022 was $4.35 million;

Consequences of Buhti ransomware HelpRansomware
  • Legal implications: data protection laws, such as the GDPR in the European Union, impose severe penalties for data breaches, which can add another layer of cost and complexity to recovering from an attack;
  • Emotional and psychological impact: the anxiety and stress associated with having one’s privacy breached through attacks such as doxing and the loss of critical data can have long-term mental health implications;
  • Risk of future attacks: Paying the ransom not only does not guarantee data recovery, but may also make you an easy target for future attacks.

Given the severity of these consequences, it is crucial to take every precaution to prevent an attack and have a plan of action in case one occurs.

Consulting with a specialized company like HelpRansomware can provide invaluable assistance in navigating the complex challenges posed by a Buhti ransomware attack.

Why be prepared?

Preparedness isn’t just a preventative measure, it’s an absolute necessity in a digital environment where threats like Buhti ransomware are becoming increasingly prevalent and sophisticated.

In fact, preparation is essential to minimize risk and loss.

It’s not just about installing antivirus software or having a robust firewall; it’s also about training and awareness.

You need to be able to recognize the social engineering tactics used and train yourself and your team to protect yourself from ransomware.

As reported by Thales, only 49% of organizations surveyed have a formal ransomware response plan, while 67% continue to experience data loss after attacks.

Why be prepared ransomware Buhti HelpRansomware

Being prepared not only helps you deal with attacks when they happen, but it can also serve as a deterrent to potential attackers.

Key Measures to Prevent the Buhti Ransomware Attack

Prevention is the first line of defense against any form of cyberattack, including ransomware.

Being proactive, rather than reactive, can mean the difference between maintaining data security and managing a crisis.

Here are some key steps every business and individual should consider to mitigate the risk of an attack.

Backup files 

Backup your important data regularly and ensure that it is stored in a separate environment that is protected from unauthorized access.

Use both local and cloud backup solutions, and regularly test the recovery process to ensure it works as expected.

It’s also important to regularly test your backups to ensure they can be successfully restored.

As reported by Unitrends, 73% of all ransomware attacks were successful in encrypting files.

Backup files ransomware Buhti HelpRansomware

Having up-to-date backups means you won’t have to resort to other measures to restore encrypted files.

Update your software

Keeping your software and operating systems up to date is critical for security and ransomware protection.

Developers frequently release security updates that patch vulnerabilities that could be exploited by malware like Buhti.

In addition to security updates, it’s important to keep all business and personal software up to date with the latest versions, which often include performance improvements and new security features.

It is also important to update security patches, which fix known vulnerabilities.

Cybersecurity training

Every team member should be trained to recognize red flags such as suspicious email addresses and unsafe URLs, which are often used in phishing attacks to deliver ransomware.

Investing in cybersecurity training programs for employees can provide a deeper understanding of emerging threats and best practices for mitigating them.

One mistake can compromise the entire network, so it’s important that everyone is aware of the risks.

Strong passwords 

Using strong, unique passwords for each service or application is another critical step in preventing ransomware.

Use a combination of letters, numbers and symbols to create strong passwords, and consider using a password manager to keep them safe.

According to Sophos analysis for the first half of 2023, 50% of hacking attacks were carried out thanks to compromised credentials.

Strong passwords ransomware Buhti HelpRansomware

To understand the importance of using strong passwords, consider that only 23% of attacks come from exploiting vulnerabilities.

Also consider using two-factor authentication, which adds an extra layer of security and makes it harder for attackers to gain access to systems.

Recommended tools and software to protect against Buhti ransomware HelpRansomware

Try to choose one with anti-ransomware features, a robust firewall, and backup software with quick recovery options.

However, no software is 100% effective, so it is important to use a combination of ransomware solutions.

Some security tools also offer real-time monitoring capabilities that can detect and block suspicious activity before it can cause damage.

On the other hand, you can increase the level of security with password management software or tools that support two-factor authentication.

For comprehensive protection, consider an integrated security suite that combines antivirus, firewall, and other security features such as ransomware decryption.

To complete the security system, use a VPN for secure web browsing.

Why is it a threat to your business?

A ransomware attack negatively affects several aspects of a business.

In terms of operational damage, it can be the loss of critical data or the leakage of confidential information.

In the first case, the impact is a technical problem: employees are unable to do their jobs and the business is paralyzed.

In the second case, the legal ramifications are greater and the damage potentially more dangerous, as not only the company’s confidential data is exposed, but also that of its customers and suppliers.

In both cases, however, we see damage to the online reputation and image of the brand it represents.

The company’s credibility is called into question, and at that point, the way the crisis is handled makes all the difference.

In fact, in an increasingly digital world, data security has become an absolute priority for companies of all sizes.
