An industrial group has fallen victim to a ransomware attack, paralyzing its IT systems and preventing all activity. The attack encrypted critical data and blocked access to production tools, directly impacting the supply chain and order management. Faced with this critical situation, management called on SEMKEL to manage the crisis, identify the attackers, limit the impact and restore the security of the information system.
To contain and remedy the attack, SEMKEL mobilized several experts in addition to its team and deployed a three-phase approach:
Isolate infected systems to prevent the ransomware from spreading
Set up a crisis bastion to coordinate response actions safely
Analyze ransomware signatures to identify the malware family and evaluate decryption options.
Identify the entry point of the attack (phishing, vulnerability exploitation, insecure RDP access, etc.)
Search for a decryption key and assess the risks involved in paying the ransom
Restore systems securely from uncompromised backups.
Correction of vulnerabilities exploited by attackers and reinforcement of sensitive accesses
Implementation of an incident response plan and cyber-resilience strategy
Communication with various stakeholders
Thanks to SEMKEL'srapid, structured intervention, the company was able to contain the ransomware attack and limit its impact on its operations.
Firstly, the threat was identified and neutralized before it compromised the entire information system, thus avoiding wider propagation and irreversible damage.
The experts commissioned by SEMKEL then succeeded in decrypting part of the encrypted data using specialized tools, enabling the company to recover essential information and limit the paralysis of its activities.
At the same time, critical systems were restored using unaltered backups. This approach enabled a gradual resumption of operations without having to give in to the attackers' blackmail.
To prevent any recurrence, the company strengthened its security by implementing advanced protection measures. This significantly reduced the risk of new attacks and improved the overall resilience of the IT infrastructure.
Finally, a training and awareness-raising component was deployed for in-house teams. Employees were trained to identify and react to phishing attempts and other cyber threats, reducing the human factor as an attack vector.
Thanks to these actions, the company was able to quickly return to normal activity, while consolidating its cyber-resilience and enhancing its ability to respond to future threats.
