Insurance industry analysts are tallying up the cost of company losses from last week's CrowdStrike outage, with a price tag ranging from less than half a million to over 1 billion dollars. This is as CrowdStrike CEO George Kurtz said on Thursday that more than 97% of Microsoft Windows Falcon sensors are back online.

World-leading cyber risk analytics firm CyberCube came out with its preliminary figures Thursday, estimating that the standalone cyber insurance market could lose anywhere from between $400mn and $1.5 billion.

CyberCube analysts said the “scale of loss could make the ‘CrowdOut’ event the largest single insured loss event in the history of the affirmative cyber insurance industry over the past 20 years.”

Still, the blog post by the CyberCube Cyber Aggregation Event Response Service (CAERS) team said those numbers would be much worse had the incident been the result of an actual cyber or ransomware attack.

The Minnesota-based spyware maker Spytech Software and Design, Inc. has allegedly been breached, and “persons with knowledge” exposed the logs of thousands of remotely monitored phones, tablets, and computers, TechCrunch reports.

The data, verified by TechCrunch as authentic, reveals that Spytech’s products Realtime-Spy and SpyAgent have been used to compromise 10,000 devices worldwide, including Android, Chromebook, Mac, and Windows devices, since 2013.

Some of the exfiltrated logs relate to the company’s CEO, Nathan Polencheck, who installed the spyware on one of his devices. When contacted by reporters, the CEO said he didn't know about the breach.

He told TechCrunch that he hadn't seen the data, and all he could say was “that I am investigating everything and will take the appropriate actions.”

Analysis of location data revealed clusters of monitored devices across Europe and America. Fewer devices were monitored on other continents. The data collected from infected devices was stored unencrypted on the company’s servers.
