French Chip Firm Semco Hacked During IPO

The French technology company Semco Technologies has reported that it suffered a significant and damaging cyberattack. Semco Technologies is a French technology company that specializes in the production of advanced semiconductor components. The company was hit by the cyberattack at the worst possible time, as it was carrying out its IPO. The initial public offering was being carried out on the Euronext stock exchange at the time of the attack. A Russian-speaking hacker group called Qilin Ransomware has now claimed responsibility for this intrusion.

The hackers have stolen several of the company’s employees’ sensitive personal data, including their passports and invoices.

These stolen files were published on a site on the dark web, which is an alternative and anonymous internet. A reporter from the French newspaper La Tribune was able to consult this dark web site and view the files. The hackers’ strategy is usually to discreetly extract sensitive documents before they demand a ransom from the company. The publication of the data suggests that Semco Technologies may have refused to pay the ransom demand.

Semco Technologies has officially confirmed the attack in a statement to the French newspaper La Tribune. The company said that it has put in place all the necessary measures to contain the attack’s impact. These measures were taken as soon as the security intrusion was detected by the company’s information technology staff. The company stated that this cyberattack did not call into question the operation of its production equipment.

More broadly, the operation of the company Semco was not significantly impacted by this particular security incident.

This incident highlights the significant and growing threat that ransomware poses to technology companies around the world. The timing of the attack during the company’s IPO seems to have been a deliberate strategic choice. This was likely intended to maximize pressure on the company to pay the ransom demand very quickly. The attack on a company specializing in semiconductor components underscores the vulnerability of the technology supply chain. This incident serves as a stark reminder for all companies to maintain robust cybersecurity defenses at all times.
