There is a very alarming problem in the WhatsApp conversation between individuals investigating President Trump’s impeachment case. these conversations were between Ukrainian official so most likely they did not cooperate themselves to provide their phone to the US official.
The logs print of messages is not the format you can extract from the message phone.
the time-stamp and send and receive has a URI of an email format that is common in EMAIL, XMPP or SIP messages. (firstname.lastname@example.org)
When you extract logs from your phone, meaning:
If you copy/paste from WhatsApp message from What or chat history, the result is this. of course the screenshot is also not in blue and green format
[14:38, 1/29/2020] Person A: How are you?
[14:39, 1/29/2020] Person B: I’m Good and you.
The log format suggests these were most likely captured by access on WhatsApp server given they are passed through SSL/TLS tunnel the likely hood of them being intercepted by the US government is not possible. that is why I believe the WhatsApp security claim for end-to-end is false.
These logs also have UTC0+ which is timezone usually set on Linux servers, neither Ukraine or US are in UTC, aka GMT Timezone.
It also indicates that Platform is Mobile, this information is not available through WhatsApp client on Android, iOS or Web or desktop version. you can only see that message is delivered or has been seen by a grey check a sign that message was received by Whatsapp server, or double grey check to indicate the message is received by the receiver phone but pending to be seen by the person. or blue check as for seen.
