Many thanks for the info!
That's a serious issue which should not get overlooked.
I just realized I donloaded Unix Electrum-Ltc on July 22nd.
Version 2.8.3.5 was supposedly released one day later. Is there any definite information to narrow down the exact timeframe of that infection?
You just wrote
the shell scriptproceeds to collect various files (wallet data for various wallets and ssh-keys)
Would that mean my sensitive data from other clients, such as Bitcoin Electrum or Jaxx wallet could be endangered?
