A security researcher has found it’s possible to reveal a Skype app user’s IP address without the target needing to even click a link. Microsoft said the vulnerability does not need immediate attention.

The attack could pose a serious risk to activists, political dissidents, journalists, those targeted by cybercriminals, and many more people.

Lmao like they're using Skype when trying to hide

[–] Potatos_are_not_friends@lemmy.world 20 points 1 year ago (1 children)

Hello. I am evil hacker cyber criminal.

If you want to discuss terms, find me on Skype at EvilHackerCyberCriminalGuy69.

Do not be fooled by the 69, as while it can be seen as a joke, it is my birth year as the original name was taken.

Thank you.

[–] TurnItOff_OnAgain@lemmy.world 4 points 1 year ago

I use 88 in stuff as well. I didn't realize until way to late that 88 is a nazi thing.

[–] Edgelord_Of_Tomorrow@lemmy.world 12 points 1 year ago (3 children)

Have to be honest, I thought Skype was discontinued years ago.

[–] RedditWanderer@lemmy.world 5 points 1 year ago

It was but we forgot to tell our grandparents, and Microsoft

[–] TonyTonyChopper@mander.xyz 4 points 1 year ago

somehow Emperor Skype returned

no matter how many times you say no it keeps coming back, same with Edge

[–] affiliate@lemmy.world 1 points 1 year ago (1 children)

i did too. i’m genuinely not sure why it exists. microsoft is making teams into its favorite productivity app, and i can’t think of anything skype has that teams doesn’t. why does skype still exist?

[–] lemmyvore@feddit.nl 1 points 1 year ago (2 children)

Because it sucks quite a bit less than Teams. I know I'll be sad to see it go when companies eventually switch to Teams. They're already running side by side in most places now while companies are migrating so it's only a matter of time. Microsoft will probably announce end of life sometime this year.

Skype basically bridged the time it took Microsoft to come up with their own conferencing solution so now that Teams is here to stay they can take Skype out back and shoot it.

[–] vacuumflower@lemmy.sdf.org 1 points 1 year ago (1 children)

Isn't today's Skype just camouflaged Teams?

[–] lemmyvore@feddit.nl 2 points 1 year ago

It's possible it uses the same infrastructure in the background, but the interface is a lot simpler. It's just on-on-one conversations and group conversations period. The equivalent in Teams would be the "Chat" tab – if it didn't have all the added complexity that comes from Teams being so deeply integrated with the Microsoft online office suite (email, calendar, teams, sharepoint, onedrive and a billion other apps).

[–] affiliate@lemmy.world 0 points 1 year ago

that makes a lot of sense. it is quite hard to make an app worse than teams, and it seems like the more time microsoft spends on their productivity apps the worse they get (ie word, which was pretty much finished in 2004). i haven’t used skype since finding out about mumble around 2013, but can definitely see why it might be nice to have an office meeting app that is (relatively) free from microsoft’s meddling.

On a serious note, most of those people (activists, journalists, etc.) aren't exactly the computer savvy types, nor have the time or resource to spend learning about matters they seldom know about, and yet they are the ones that desperately need this knowledge. They might have an important message to be sent. What would you use to spread the message in their shoes?

Sure, we the tech guys, especially subscribed to privacy related communities, can talk about Tor browser or threat modeling all day. But have you tried bring that up in social circles, if any?

Non tech minded activists will simply use the tools at their disposal: messaging apps? sure; social media apps, if looking for message amplification, whatever it runs on their cheap android phone. Metadata? IP? Profiling? Browser fingerprinting? Some are aware of it, as they also had to endure internet censorship growing up. It's a trade they make knowingly or unknowingly between the cause and their physical and mental health.

We can laugh at their ignorance all we want, but this is how we become the Ivory tower that fuels resentment.

[–] havokdj@lemmy.world 44 points 1 year ago (2 children)

Is this even news? Literally an exploit as old as time.

[–] Bearigator@ttrpg.network 9 points 1 year ago

I remember my friends and I doing this in 2008. This really is super old

[–] BradleyUffner@lemmy.world 44 points 1 year ago (2 children)

Ohh no, someone on the Internet might have my IP address! The horror! What if they try to ping me?!

[–] RheingoldRiver@kbin.social 8 points 1 year ago* (last edited 1 year ago)

People used to use this attack in League of Legends a decade ago. If they're losing, they guess someone might have Skype open; and moreover, that their Skype is the same as their summoner name. Then they get an ip address and ddos the entire lobby, causing the game to crash (I think it happened in one of my games maybe once, but I didn't really play ranked other than team ranked).

Also, since all pro & semipro players had each other added, this was possible to do at any time during online tournaments (which was most tournaments - TSM invitational etc). So there were always rules that ddossing was disallowed. But it did happen.

Known ddossers were more hated in the community than known flamers, but a few people who did it "reformed" and went on to be pro players anyway.

[–] sugartits@lemmy.world 4 points 1 year ago (1 children)

What if they leave an anonymous tip that you're distributing CSAM?

[–] SkyeStarfall@lemmy.blahaj.zone 24 points 1 year ago* (last edited 1 year ago) (1 children)

With just an IP? Then the system is broken. Because an IP is often easy to get, and everything that directly connects to you needs your IP, unless you use a VPN I guess.

Every website knows your IP. Every internet application knows your IP. Everyone in a peer-to-to-peer network knows your IP. It's not a secret, it's just your internet address. It is designed to be known.

[–] Sethayy@sh.itjust.works 6 points 1 year ago

Yk I was on the others side of this til this comment, like I was gonna say there's a difference between corporations and malicious individual actors, but nowadays I'd trust some random individual 1000x before a company.

God I hope veilied becomes popular

[–] jrest18n@lemm.ee 31 points 1 year ago

When Skype was still in common use, this was a very known issue. I’m in lots of gaming communities, and you had to be careful about who knew your username because you could have your IP exposed then get DDoS.

Possibly they patched it and this is a new instance of this, but it was like this for years and years before.

[–] Cheems@lemmy.world 20 points 1 year ago

Now, that's a name I've not heard in a long time.

[–] howrar@lemmy.ca 19 points 1 year ago (2 children)

If you connect to anything on the internet, you're giving out your IP address. Why would this be any more of a concern?

[–] TORFdot0@lemmy.world 14 points 1 year ago

Users may consent to giving Microsoft their IP address but not to everyone who sends them a link

[–] brianorca@lemmy.world 3 points 1 year ago (1 children)

Because this can happen without you connecting to any suspicious server.

[–] Sethayy@sh.itjust.works 3 points 1 year ago

At this point Microsoft is a suspicious server, and any data they could get from this they could just like... pay for from one of our overlords

[–] dyc3@lemmy.world 14 points 1 year ago (1 children)

This is not new. It's literally always been like this.

[–] Redditiscancer789@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

Lol I love how behind the times academics can be. This literally was a big thing used to ddos streamers back in the day like 2010s-2015s. All that needed to happen was they accepted a call and since Skypes peer to peer the hacker instantly got their IP. I remember Destiny being targeted for a while by it.

[–] Franzia@lemmy.blahaj.zone 14 points 1 year ago

What the fuck. What percentage of people uses skype? I'd really rather see coverage of the exploits found in discord, zoom, slack, etc.

[–] Swim@lemmy.ca 13 points 1 year ago

This is soo old that's how they would ddos clan leaders and shot callers back in the acheage days

[–] artvabas@lemmy.world 8 points 1 year ago (2 children)

Who is using Skype these days!

[–] LinusSexTips@lemmy.world 3 points 1 year ago

Was common practice in procurement for me and my team, still have contacts at ASRock / Keychron / Logitech / SteelSeries / Beacn / HYTE / Maxsun and many more.

Was a platform that was used early on and has carried through. Factories in China will commonly use WeChat but many of the more mainstream western brands will default to Skype.

[–] Redderthanmisty@lemmygrad.ml 1 points 1 year ago

Still a thing for some enterprise users... and the elderly.

[–] Raptor_007@lemmy.world 7 points 1 year ago

Silently? They don’t even tell you they’re doing it? 😕

[–] HawlSera@lemm.ee 7 points 1 year ago

There ia Very Probably No solution to this

[–] jet@hackertalks.com 7 points 1 year ago

Always on VPN is a good idea, or a VPN just for apps you don't trust (like skype). https://github.com/Safing/portmaster is a nice visual firewall configurator that can do things like, this app, must use the firewall. (easy to configure split firewall)

[–] GustavoM@lemmy.world 6 points 1 year ago

Man, Justin Bieber is such a fa-- wait. We aren't in the 00's anymore?

[–] ShittyRedditWasBetter@lemmy.world 4 points 1 year ago (1 children)

Because nobody cares. At all. The only people who might are streamers and over zealous nerds.

[–] Kolanaki@yiffit.net 4 points 1 year ago (1 children)

Even an overzealous nerd would understand knowing an IP address is pretty much worthless.

You underestimate how much privacy advocates bitch over the dumbest shit ensuring that nobody ever actually listens when it's important.

[–] AnonTwo@kbin.social 3 points 1 year ago

Pretty sure this was already known. Just even back when Skype was relevant it wasn't fixed.

[–] canis_majoris@lemmy.ca 2 points 1 year ago

Huh, the time machine must be off. This was news from a decade ago.

It's actually one of the main reasons we switched off Skype to Discord for most gaming socialization.

[–] silvercove@lemdro.id 2 points 1 year ago

Is anyone still using Skype? Or is this a danger just to the last 10 people using it?

[–] Treczoks@lemmy.world 2 points 1 year ago

They only fix bugs that otherwise would impact their earnings.

[–] skymtf@lemmy.blahaj.zone 1 points 1 year ago

How exactly would you stop this on a peer to peer app exactly, wouldn't you have to route traffic through a centralized proxy?
