In February 2023, C.S.E, a subsidiary of Aker Solutions, fell victim to a cyber attack where threat actors infiltrated its IT infrastructure. The attackers successfully encrypted digital files and locked access to critical data, effectively disrupting operations. While the breach was contained to C.S.E’s systems, there was no evidence suggesting lateral movement into Aker Solutions’ broader IT environment. The incident aligns with a ransomware-style attack, where data was rendered inaccessible, likely for extortion purposes. The company did not disclose whether a ransom was demanded or paid, nor the extent of operational downtime. However, the attack’s focus on data encryption and system lockdown indicates a deliberate attempt to cripple business continuity, posing significant financial and reputational risks. The isolation of the incident to C.S.E mitigated broader corporate exposure, but the localized impact remained severe, particularly if critical project files or proprietary data were compromised.
