2016-08-23 I fell for a malware mail, thankfully aimed at Windows users1 year ago
Today I saw an incoming e-mail about a voicemail message, while I was expecting a voicemail message. The format was quite similar to the format used by my telephone provider so I tried opening it in thunderbird under Linux. That saved me, it was aimed at opening in Windows, probably only working in Microsoft Outlook. This is what it looked like in mutt:Dear koos : There is a message for you from 01427157659, on 2016/08/23 15:52:17 . You might want to check it when you get a chance.Thanks! [-- Attachment #2: Voicemail sound attachment. --] [-- Type: audio/x-wav, Encoding: base64, Size: 10K --] [-- audio/x-wav is unsupported (use 'v' to view this part) --]The attachment is Message_from_01427157659.wav.zip but with mimetype audio/x-wav. The zip file contains:Archive: Message_from_01427157659.wav.zip Length Date Time Name --------- ---------- ----- ---- 30764 2016-08-23 12:18 614007286106.wsf --------- ------- 30764 1 fileWith a lot of obfuscated scripting. What saved me this time was opening it in a mailreader/environment which tries to play an audio/x-wav file with a mediaplayer which complained about something being invalid in it.
