Your weekly cyber security news round-up includes accidental sharing of sensitive data and a big cyber war game....
It has emerged that the Microsoft Office 365 document sharing tool has caused some organisations using it to share sensitive information accidently.
The information, found by security researchers is likely to have been shared globally by mistake, instead of with colleagues internally.
“It (Office 365) defaults to publicly accessible, which is the problem” wrote Kevin Beaumont, a security researcher. “People clearly don’t understand how it works.”
Information found included passwords, national insurance numbers and access codes.
Microsoft said in a statement: "As part of our commitment to protect customers, we're taking steps to help those who may have inadvertently published documents with sensitive information." They went on to say, "customers can review and update their settings by logging into their account at www.docs.com."
If you use Office 365, be sure to check your settings immediately.
The Royal Navy is holding its first big cyber war game, which will test how well protected warships and submarines are to cyber attacks.
The exercise, Information Warrior 17 will “set the foundations” as technology advances to help the Royal Navy combat cyber threats and attacks.
The training, which is part of Joint warrior, a NATO exercise that occurs twice a year which this spring will include naval units from Denmark, Belgium, Estonia, France, Germany, Netherlands, Norway, Spain, Sweden and the US, and involves thousands of personnel from the army, navy and air force.
The exercise will use AI technology, open source intelligence and satellite imagery and will test defences on ships and submarines.
