Packet Sniffing solutions - Help needed

#1SetzeraPosted 9/1/2014 7:12:52 AM
I've got a friend here who believes she is being packet sniffed and data logged. But, there's a twist to this problem, which is why I've come for help.

She's got a roommate that seems to be logging her private chat Facebook conversations, and later editing them to say inappropriate things (locally, not actually on Facebook's server). They share the same internet and router, so changing wifi password won't help.

What are the options here for stopping data logging?

That's not possible. Data is sent over networks encrypted.

The odds of them doing that via packet sniffing are pretty small. The reason why is all facebook traffic is HTTPS, so they can sniff the hell out of that traffic, but they're not going to be able to actually see the messages unless they're doing a much much more elaborate man in the middle attack.

I'm willing to bet it's something much much more basic/easier/simplier. Since facebook shares chat screens across all logged in accounts. I'd put some money down they're just logging in as them and watching the conversations

Not all data. If you're already on the network, like the roommate is, you can sniff a crapton of unencrypted data. Facebook just isn't one of those since they force HTTPS

Hmm, well if it's not data logging because of Facebook's HTTPS encryption, what other ways could they theoretically gain access to private chats?

They have the facebook password obviously.

Log into Facebook and you will find something like this:

It tells you every computer that is logged into your facebook account.

I answered that :)

Just logging into facebook as them. Facebook shares the chat across the screens/logged in account. So they could either be logging in and watching when she chats, or logging in latter and just looking at the chat history. If she's deleting stuff but they're still doing it I'm betting the former.

I completely forgot about that, thank you. I'll get her to do that now, and see what she finds.

Welp, she didn't find anything, so she thinks it might've been an empty threat. All they really said was they'd get her information by "data phishing her packets". Which I know, makes literally no sense.

She's going to do some "recon" and find out the knowledge level of this person, to see if they are even capable. I have a feeling she'll be fine >_>

Sorry for wasting everyone's time, but thank you for the responses. If I had known nothing had actually happened yet, I wouldn't have made a topic.
