Preventing a Ransomhub ransomware attack involves a comprehensive cybersecurity framework. Below, we’ve listed essential points to consider.

Organization – Detailed documentation of the IT infrastructure greatly assists in the prevention process, alongside organized management of networks and computers. It is also essential to establish guidelines so new employees understand company policies regarding the installation and use of software on company computers.

Strong Passwords – Passwords should contain more than eight characters, including regular and special characters. Additionally, it’s crucial not to reuse the same password across multiple accounts.

Security Solutions – A reliable antivirus should be installed and kept updated, as should the operating system. It’s crucial to have a Firewall and endpoint protection to keep the system secure.

Caution with Suspicious Emails – One of the most common entry points for hacker groups is spam email campaigns. Therefore, creating a security policy and educating employees about not downloading attachments from unknown emails is essential.

Effective Backup Policies – Backups are among the most critical measures for protecting company data. However, many organizations neglect backups or implement ineffective backup schedules. We’ve handled cases where backups were encrypted along with the original data. Creating a consistent backup update routine and avoiding exclusively online backups is crucial. The best practice is the 3-2-1 backup rule, involving three backup copies—two online and one offline—combined with a regular update routine.

Caution with Unofficial Software – Numerous paid software applications, such as Windows, Office, and others, are offered for free online. Although they appear cost-effective, such software can serve as gateways for future hacker attacks. Official software requires investment but ensures significantly higher security than unofficial free versions.

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

All these tactics have the same goal: gaining unnoticed access to the victim’s system. For this purpose, ransomware often camouflages itself within the system to avoid detection by defense mechanisms. In methods relying on user action, phishing techniques are used to trick victims into unknowingly downloading ransomware onto their systems.

It’s important to keep an eye out for some signs that may indicate the presence of a ransomware attack in progress.

These include an increase in the consumption of processing resources, memory and disk access, which may indicate the execution of encryption or data exfiltration by the malware.

Another way of detecting the attack is by observing changes in file extensions, which are a direct result of the encryption carried out by the ransomware. However, this form of detection can be more complex in attacks that try to mask their activities to avoid detection.

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

But in cases where the attacking group uses the tactic of double extortion, which consists of copying and extracting all the files and encrypting the original data, the situation is even more serious, because in addition to the encryption, the stolen files will be made public if the ransom is not paid. In such cases, formatting the affected device is inevitable.
