Alphabet, the parent company of Google, reduced its investment in cybersecurity firm Crowdstrike, as disclosed in a regulatory filing last Friday. The stake was decreased from 855,789 shares to 427,895 class A shares, effective as of June 30.

Crowdstrike has not yet responded to a request for comment from Reuters. A worldwide technological disruption on July 19, resulting from a software update by Crowdstrike, led to widespread system failures across various industries such as healthcare, banking, and aviation.

Following the outage, Crowdstrike shares have plummeted by nearly 35%, prompting investors to reassess their security measures and regulators to question the safety of entrusting complex and critical software to large corporations.

Shareholders filed a lawsuit against the company on Wednesday, alleging that misleading information about its software caused the global outage.

Delta CEO stated on CNBC earlier this week that the airline incurred a $500 million loss due to the outage and has enlisted legal assistance to pursue compensation from Microsoft and Crowdstrike.
