This undated screenshot taken by researchers at the London-based Certfa Lab shows a bogus, Farsi-language interview request purportedly sent by journalist Farnaz Fassihi. The message was one of several malicious emails sent in the name of real life journalists working for CNN, Deutsche Welle, and other publications. The reporters had nothing to do with the messages, which Certfa believes were sent by an Iran-linked hacking group often nicknamed Charming Kitten. Certfa/Handout via REUTERS
