New York, USA.- Warning customers that bad actors were trying to take advantage of the event, CrowdStrike said it had identified a malicious file sent by hackers posing as a “quick fix” to the problem, The Wall Street Journal noted.
In a blog post, the company said a file called “crowdstrike-hotfix.zip” was being distributed that included malware that allowed hackers to remotely control or monitor a user’s device.
The paper noted that the CrowdStrike flaw that caused disruptions to millions of Microsoft Windows device users last week continued to shake industries and hamper global air travel.
Around 8.5 million devices were affected by the outage, CrowdStrike said in a statement, adding that it had brought a significant number back online.
Microsoft reported that it has resolved the failure in the 365 applications and services, which affected the systems of airports, banks and media outlets, among others. However, it noted that certain problems continue for some customers and that delays and cancellations are still being reported at many airports.
Travelers faced a fourth day of flight disruptions and long waits at U.S. airports as airlines struggled to overcome disruptions caused by the outage.
Delta Air Lines, one of the hardest hit over the weekend, had canceled more than 600 flights by 7 a.m. Eastern time, according to flight tracking website FlightAware.
In the UK, health services were working to fix disruptions to the appointment and patient registration system used by most GP surgeries.
Doctors’ surgeries and pharmacies across the UK have returned to using pen and paper to fill prescriptions and schedule appointments.
Windows computers and tablets crashed Friday in countries from the United States to China to Australia, shutting down business and service operations across nearly every industry.
The problems arose from an update to one of CrowdStrike’s main services, Falcon, which monitors a company’s machines for hacking attempts, viruses and other threats. CrowdStrike told customers in a status update that the problem was in a software change it had pushed through Falcon to customers’ computers.
