Singapore sting: How spies listened in on German general

Berlin said human error was to blame for the intercept of conversations between top military officers.

Four German military officials discussed what targets German-made Taurus missiles could potentially hit if Chancellor Olaf Scholz ever allowed them to be sent to Kyiv, and the call had been intercepted by Russian intelligence.

According to German authorities, the “data leak” was down to just one participant dialling in on an insecure line, either via his mobile or the hotel wi-fi.

The exact mode of dial-in is “still being clarified”, Germany has said.

“I think that’s a good lesson for everybody: never use hotel internet if you want to do a secure call,” Germany’s ambassador to the UK, Miguel Berger, told the BBC this week. Some may feel the advice came a little too late.

Eyebrows were raised when it emerged the call happened on the widely-used WebEx platform - but Berlin has insisted the officials used an especially secure, certified version.

Professor Alan Woodward from the Surrey Centre for Cyber Security says that WebEx does provide end-to-end encryption “if you use the app itself”.

But using a landline or open hotel wi-fi could mean security was no longer guaranteed - and Russian spies, it’s now supposed, were ready to pounce.

      In this case shit software. For a secure conference software there should be no possibility for the user to accept invalid certificates.

      The developer always has to plan with what we call a DAU in germany (Dümmster anzunehmender User = dumbest user possible), and even that user should have no possibility to accidentally share a secure conference. So as a developer I would: Lock the user to certificates and encryption keys I deem secure and hook into the low level OS functions to grab the screen and disable them to prevent accidental sharing via software like Anydesk and the like which the user forgot to close. This would even interrupt the functions of a simple trojan on the PC.

      Of course a dedicated attacker with physical or admin access to the device could always break these. But then you have another big security breach.
