Decrypt VIB Files

Preventing a Ransomhub ransomware attack requires a comprehensive cybersecurity framework. Below, we outline key points that should be considered:

Organisation – Documenting your IT infrastructure is highly beneficial for prevention, along with maintaining proper organisation of networks and devices. It’s also essential to establish rules so that new employees understand the company’s policy regarding software installation and usage on workstations.

Strong Passwords – Passwords should contain more than 8 characters, including letters, numbers, and special symbols. It’s also important not to reuse the same password across multiple accounts.

Security Solutions – A reliable antivirus must be installed and kept up to date, as well as the operating system. A firewall and endpoint protection are also essential to keep the system secure.

Beware of Suspicious Emails – One of the most common intrusion methods used by hacker groups is through spam email campaigns. That’s why it is vital to implement a strong security policy and raise employee awareness to avoid downloading attachments from unknown senders.

Effective Backup Policies – Backups are one of the most important measures for protecting company data. Nevertheless, many organisations neglect this or implement ineffective backup schedules. We’ve seen cases where both the data and the backups were encrypted. It’s crucial to establish a consistent backup update routine and not rely solely on online backups. The recommended backup structure is the 3-2-1 rule: 3 copies, 2 stored online, and 1 offline — along with a consistent update schedule.

Be Cautious with Unofficial Software – Many paid programs are available online for free, such as Windows, Office, and others. Although they may appear to be free, such programs can act as a gateway for future hacker attacks. Official software may require investment, but it offers a significantly higher level of security compared to free alternatives.

To carry out ransomware attacks, criminals use various strategies such as downloading infected files, malicious links, RDP attacks, spam email campaigns, and others.

All of these methods have the same goal: to access the victim’s system without them noticing. To achieve this, ransomware disguises itself within the system to avoid detection by security tools. In tactics that rely on user action, phishing techniques are used to trick the victim into unknowingly downloading the ransomware onto their system.

It is important to be alert to certain signs that may indicate a ransomware attack is in progress.

Among them are increased usage of processing resources, memory, and disk access, which may suggest that the malware is encrypting files or exfiltrating data.

Another way to detect the attack is by observing changes in file extensions, which are a direct result of the encryption carried out by the ransomware. However, this method of detection can be more difficult in attacks that attempt to mask their activity in order to avoid being detected.

Once data has been encrypted by ransomware, the only way to recover it is by paying the ransom demanded by the criminal group. However, there is no guarantee that the data will be released, and payment may encourage the group to continue their attacks.

In cases where the attackers use the double extortion tactic — which involves copying and extracting all files in addition to encrypting the original data — the situation is even more serious. Beyond encryption, the stolen files will be publicly leaked if the ransom is not paid. In such scenarios, formatting the affected device often becomes unavoidable.
