Following reports of a ransomware attack, Taiwanese PC vendor MSI (short for Micro-Star International) confirmed today that its network was breached in a cyberattack.

Earlier this week, the Money Message ransomware gang claimed to infiltrate some of MSI’s systems and stolen files that will be leaked online next week if the company refuses to pay a $4 million ransom.

In a Friday filing with Taiwan’s Stock Exchange (TWSE), first spotted by PCMag, MSI revealed that some of its information service systems had been affected by a cyberattack reported to the relevant authorities.

“After detecting some information systems being attacked by hackers, MSI’s IT department has initiated information security defense mechanism and recovery procedures. The Company also has been reported [sic] the anomaly to the relevant government authorities,” MSI said.

The company did not share any details on the timing of the attack, about if any of the affected systems were encrypted, or if the attackers exfiltrated business and customer information during the incident.

However, MSI did say that the cyberattack has had no “significant” operational and financial impact, with security enhancements implemented to ensure that data stored on affected systems is secure.

“No significant impact our business in terms of financial and operational currently. The Company is also enhancing the information security control measures of its network and infrastructure to ensure data security.”

MSI also published a statement on Friday warning customers to ensure that they get their BIOS and firmware updates from official sources.

“MSI urges users to obtain firmware/BIOS updates only from its official website, and not to use files from sources other than the official website,” the company said.
