I write message on whatsapp to stranger

I wrote few messages with girl on fotka.com (something like tinder and badoo). Girl is from Nigeria. She gave me her whatsapp’s number (with localization based in Nigeria). I downloaded whatsapp and wrote 1 message. Now I think it was silly and very,very irresponsible! And know my question is: what can be done with my number? Does someone can use it for something? Please answer me.

External IP address in router UPnP settings Whatsapp – UK Ministry of Defence IP Address?

I was fiddling with my router’s UPnP settings and found this

enter image description here

Why is an external IP address showing here?

I also did a reverse IP search and to my surprise the IP showed "UK Ministry of Defence". I am not in the UK military or on a military base.

Something fishy going on? I have already disabled Upnp.

How can an Android app like Whatslog detect user online status from Whatsapp?

Whatslog on Android allows you to check the online status of whatsapp users. You don’t need to scan a whatsapp qrcode, you just have to enter a phone number and it works pretty well.

I don’t understand how they do it.

  • I’m pretty sure they don’t use web.whatsapp.com because they don’t ask any QR code furthermore I have reverse-engineered the apk to java with jadx and I don’t see any trace of them using any “hidden” whatsapp api or anything like that.

  • I don’t see any communication between Whatslog and Whatsapp through Android Intents or the like.

There is this question which discusses the same thing but the answers talk about web.whatsapp but I’m pretty sure it’s not what they use : How can application like Whatsdog detect user online status from Whatsapp?

Locate WhatsApp message destination

I’ve been interested in message tracing, so I played a bit with Cisco’s Packet Tracer and Wireshark.

Is it possible to locate the destination of a message (packages) been sent via WhatsApp? I am not trying to read data out of the packages, I just wonder if it is possible to trace the destination location of the message which has been received.

Is WhatsApp end-to-end encryption applied to images?

I know that for text, WhatsApp messages are encrypted in a way no “man in the middle” could read them. But what about images?

Imagine you received some private image on your smartphone. Then you open WhatsApp Web on your PC, which uses an employer VPN.

Would the employer be able to “download” the image your Whatsapp Web just loaded?

Is Signal still more secure when compared to WhatsApp and Telegram?

I have recently been reading several articles about Signal and (suposedly) how secure it is next to other well-known apps like WhatsApp and Telegram, both of which are claimed to be less private due to both using external servers. I saw here that Signal apparently uses the same protocols as WhatsApp, which does not fill me with confidence due to it’s use in WhatsApp, and only blurs the picture more for me.

Is Signal still more secure compared to WhatsApp?

EDIT: It has been highlighted to me that there is a very similar question about WhatsApp and Signal from 2016, but it has not been updated since 2016, So unless the information in that answer is still accurate (which I’m not sure is the case) I’m going to keep my question open.

What’s the scam? Unknown users joining and leaving WhatsApp groups

I’m on a few WhatsApp groups that have signup links. Lately (last few months) I’ve noticed some very odd activity on a few of these groups: every few days I notice a number (often from a country with a poor reputation for scamming) joining, and then leaving the group, like this:

enter image description here

And I’m wondering, what is the scam being cooked up here? Have they got some kind of brute force bot that signs up for whatever WhatsApp groups it can find? And then does…what? Scrolls through the group member list and harvests their phone numbers? To do…exactly what with them? Send SMS spam, telling people they’ve won the $ 16.4m Bill Gates Philanthropic Award For Owning a Phone?

If that’s the extent of the threat, then I can live with it. But is there anything else these bots could be doing that is more sinister?

Can someone hack my phone by sending me a file (e.g. PDF) via Whatsapp?

My work requires (and depends on) Whatsapp for daily sharing of files with many people (PDF, PowerPoint, Word, Images, Web links…), and I was wondering if it is possible that someone can hack our phones by sending us malware via Whatsapp.

For example, let’s say they send me a virus that pretends to be a legitimate PDF. Is it okay to “just install it” on Whatsapp? What happens if I installed it but never opened it? Can that affect my phone or I have to open/view it?

This is extremely important to me and my team, and I will share your answers with them because we seriously need more awareness on this. Thanks!
