Preventing a Ransomhub ransomware attack requires a comprehensive cybersecurity structure. Below are key points that should be considered:

Organization – Proper documentation of the IT infrastructure plays a critical role in prevention, along with organizing networks and devices. It’s also essential to establish clear rules so that new employees understand the company’s policy on installing and using software on corporate computers.

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

Security solutions – A reliable antivirus program should be installed and kept up to date, along with the operating system. It’s also essential to have a firewall and endpoint protection in place to safeguard the system.

Beware of suspicious emails – One of the most common attack vectors used by hacker groups is spam email campaigns. Therefore, it’s crucial to implement a security policy and raise employee awareness to avoid downloading attachments from unknown sources.

Effective backup policies – Backups are one of the most important measures for protecting a company’s data. However, many organizations either neglect them or use ineffective backup schedules. We’ve handled cases where both the data and backups were encrypted. It’s important to have a consistent backup routine and to avoid relying solely on online storage. The recommended structure is the 3-2-1 model: 3 backups, 2 stored online and 1 offline, with regular updates.

Beware of unofficial software – Many paid programs like Windows, Office, and others are available for free online. Although they may appear legitimate, these programs can serve as a gateway for future hacker attacks. Official software may require investment, but it offers significantly higher security than free or pirated alternatives.

To carry out ransomware attacks, cybercriminals use a variety of strategies, such as downloading infected files, malicious links, RDP (Remote Desktop Protocol) attacks, spam email campaigns, and more.

All of these techniques share the same goal: to access the victim’s system without being detected. Ransomware typically disguises itself within the system to evade detection by security tools. In methods that rely on user interaction, phishing tactics are commonly used to trick the victim into unknowingly downloading the ransomware onto their system.

It’s important to watch for certain signs that may indicate a ransomware attack is underway.

Among them are increased usage of processing power, memory, and disk access—these could suggest that the malware is actively encrypting or exfiltrating data.

Another way to detect an attack is by monitoring changes in file extensions, which is a direct result of the encryption process carried out by the ransomware. However, this method can be more challenging in cases where the attack is designed to mask its activity and avoid detection by security systems.

Once data has been encrypted by ransomware, the only apparent way to recover it is by paying the ransom demanded by the criminal group. However, there’s no guarantee the data will actually be released—moreover, paying the ransom can encourage the attackers to continue targeting other victims.

In cases where the group uses a double extortion tactic—copying and exfiltrating all files in addition to encrypting the original data—the situation becomes even more serious. Not only is the data encrypted, but the stolen files may be publicly exposed if the ransom isn’t paid. In such scenarios, formatting the affected device is often unavoidable.
