SUEZ, EGYPT - MARCH 29: The container ship 'Ever Given' is refloated, unblocking the Suez Canal on March 29, 2021 in Suez, Egypt. This morning the container ship came partly unstuck from the shoreline, where it ran aground in the canal last Tuesday, and later resumed its course shortly after 3pm local time. The Suez Canal is one of the world's busiest shipping lanes and the blockage had created a backlog of vessels at either end, raising concerns over the impact on global shipping and supply chains.

(CNN Business) —  

The cybersecurity company CrowdStrike, which has been at the center of false conspiracy theories since 2016, is once again in focus after a White House transcript published on Wednesday revealed President Donald Trump brought it up in his July call with Ukrainian President Volodymyr Zelensky.

In a complaint released on Thursday by the intelligence community, a whistleblower expressed confusion about Trump’s references to the company.

What is Crowdstrike?

Founded in 2011, Crowdstrike sells its “Falcon” cybersecurity software to big corporations and government clients, including major global banks, healthcare and energy companies, according to the company. Among its customers are Goldman Sachs, Amazon Web Services, MIT and various US states and cities. Crowdstrike says Falcon protects files saved in the cloud.

The company also helps run cybersecurity investigations for the US government. For example, Crowdstrike has tracked North Korean hackers for more than a decade, the company says. It also was tasked with tracking the hacking groups that carried out the 2014 hack on Sony Pictures.
