Decrypt TOHJ ransomware files

Have your files been locked by TOHJ ransomware? Act fast to safely restore your data.

Ransomware has become a critical threat to companies of all sizes and industries due to the significant increase in attacks in recent years. Studies indicate that in over 70% of cases, data is completely encrypted, leading about 56% of victims to pay criminals the ransom. Fortunately, there are effective technical alternatives to recover data without making any payment to attackers.

TOHJ ransomware is an advanced form of malware specifically designed to encrypt essential files on business and personal systems, making them completely inaccessible to their owners. This ransomware has become widely known for its ability to cause significant disruptions to critical operations, particularly affecting sectors such as healthcare, manufacturing, education, and finance.

Unlike traditional threats, TOHJ ransomware is managed by highly organised criminal groups that employ powerful encryption (AES-256 or RSA) to render data inaccessible except through a unique key held by the attackers.

It is also quite common for ransomware to employ double extortion strategies, where criminals copy important files before encrypting them, using the threat of public exposure of stolen data as an additional pressure tactic on victims.

Ransomware attacks have shown accelerated growth, increasing approximately 5% in the past year alone, with the average ransom demanded by criminals reaching millions of dollars. Many organisations, due to lack of effective recovery methods, end up yielding to the demands and funding further attacks.

Answers from our experts

How does the TOHJ ransomware attack work?

The TOHJ ransomware attack typically occurs in several well-defined stages:

  • Silent infiltration: The first stage of the attack involves phishing techniques, where criminals send emails with malicious links or attachments to victims. Another common strategy includes exploiting technical vulnerabilities in outdated systems, such as flaws in old programs or insecure remote access (RDP).
  • Backup mapping and neutralisation: After initial infiltration, the ransomware performs detailed mapping of the internal network, targeting strategic files and available or online-connected backups, aiming to neutralise these backups to prevent rapid recovery.
  • Mass encryption of files: Once the mapping of important files is complete, ransomware promptly initiates its encryption. Vital files including databases, ERP systems, virtual machines, and RAID systems are generally impacted, resulting in complete data inaccessibility.
  • Financial extortion: Once files are encrypted, attackers leave a ransom note with detailed payment instructions. Instructions frequently suggest contacting via anonymous platforms or the dark web, demanding cryptocurrency payments to make tracing virtually impossible.

How much does it cost to decrypt TOHJ ransomware?

The precise cost for recovering files encrypted by TOHJ ransomware varies depending on the severity and specific technical characteristics of the attack.

The total cost of the process is directly linked to the amount of affected information, the category of impacted systems (servers, virtual machines, storages, or databases), and the availability of usable backups.

To expedite the process and obtain a precise and personalised assessment, we recommend contacting our specialists directly for an initial diagnosis. Request specialised support right away.

How long does the data recovery take?

The timeline for data recovery varies according to the specific circumstances of each attack. Generally, the process can range from a few days to several weeks, mainly depending on the volume of affected files, the extent of the impacted infrastructure, the complexity of the ransomware involved, and the condition of available backups.

Once we perform the initial diagnosis, which occurs within the first 24 business hours after your contact, we will provide a precise and detailed estimate of the timeframe necessary to successfully complete your data recovery.

Is there any guarantee for data recovery?

Considering the technical complexity of ransomware attacks, no responsible company can guarantee in advance the complete recovery of files. Each incident presents unique technical aspects, such as different cryptographic algorithms and specific methods employed by criminals.

Nonetheless, Digital Recovery has specialized and exclusive technologies, such as the proprietary TRACER solution, achieving a high rate of success in recovering files encrypted by ransomware.

What you need to know

To prevent TOHJ ransomware attacks, it is important to have a comprehensive cybersecurity framework in place. However, there are some additional key points that you should keep in mind:

  • Organisation: Keep documentation of your IT systems and maintain an inventory of all networks and computers. Establish clear rules for new employees on the installation and use of software programmes on company computers.
  • Strong Passwords: Use strong passwords with at least 8 characters, including special characters, and avoid using the same password for multiple accounts.
  • Security Solutions: Install a reliable antivirus software and ensure that all software programmes, especially the operating system, are kept up to date. In addition to antivirus software, also consider installing a firewall and endpoint protection to provide comprehensive security.
  • Beware of Suspicious Emails: Email is a common method used by hackers to infiltrate systems. Train employees to recognise and avoid downloading attachments from unknown senders.
  • Efficient Backup Policies: Backups are crucial in the event of a ransomware attack, but many companies fail to create an effective backup plan. The recommended backup structure is 3x2x1, which means having 3 backups, 2 online and 1 offline, and regularly updating them.
  • Beware of Unofficial Programmes: Avoid downloading unofficial, free versions of software programmes like Windows or Office, as they may be infected with malware. Invest in official software programmes, as they are a good long-term investment and are also more secure.

The most common means of access used by TOHJ hackers to break into environments is through exploiting vulnerabilities in software, hardware, or human behaviour. This can include:

  1. Phishing attacks: Hackers use fraudulent emails, social media messages, or phone calls to trick individuals into revealing their login credentials or other sensitive information.
  2. Password attacks: Hackers use various techniques, such as brute force or dictionary attacks, to guess or crack passwords.
  3. Malware: Hackers use malicious software, such as viruses, worms, or Trojans, to infect computers or other devices and gain access to sensitive data.
  4. Software vulnerabilities: Hackers use known vulnerabilities in software, such as operating systems, web servers, or applications, to gain unauthorised access to a system.
  5. Misconfigured or unpatched systems: Hackers exploit weaknesses in system configurations or outdated software that has not been patched or updated to gain access.
  6. Social engineering: Hackers use social engineering techniques, such as pretexting or baiting, to manipulate individuals into divulging sensitive information or granting access to secure systems.

To reduce the risk of a successful attack, it’s important to implement security best practises, such as strong passwords, two-factor authentication, regular software updates and patches, employee security awareness training, and the use of security tools like firewalls, intrusion detection systems, and antivirus software.

Suspicious behaviour such as high usage of processing, memory, and disk access should be thoroughly investigated to determine if a ransomware attack is in progress. TOHJ Ransomware typically exploits a machine’s own resources to carry out the encryption process and exfiltration of data. Detecting the attack can also be done by observing changes in file extensions, although this method is more complicated as the encryption process may have already started.

If your machine is affected by TOHJ ransomware, your data will be inaccessible until the encryption is removed. Unfortunately, removing the encryption typically requires formatting the affected machine, which will result in the loss of all stored data.

However, some ransomware attackers also use the double extortion tactic, which involves copying and extracting all files from the affected machine and then encrypting the original data. In such cases, the attackers may post the stolen files on their website or Dark Web forums while keeping the original data encrypted on the affected machine. In such scenarios, formatting the device will not recover the original data, and the only way to retrieve the stolen files may be to pay the ransom or seek professional help.
