Anti-DOS script? (Python)

[Killervolt]

Hey people

So some of my mates made an imessage spam script that spams you a lot, and yeah I know it's just for fun, but also I was wondering how I would be able to create my own DOS protection script in python. I don't have a vast amount of knowledge of DDOS/DOS, Python, Scripts etc., so I'm looking for some help to creating a script to filter out all these spam messages. Also it would give me a sense of achievement, so any help would be appreciated. Thanks

Doesn't sound like a DOS attack... more like a flood of messages in skype, or hangouts, or something?  What is it?  That's going to matter

No maybe not, but it's imessage spam. (read the first sentence)

1. Wrong section

2. DoS is when you actually incur a loss of services (ie. phone/computer stops working)

Yeah, not really a DoS in any form of the word.

Honestly I'm not even sure how you'd prevent that on an Apple device...

"Block number"

I've never owned an iOS device, so I didn't know that feature existed on iOS.

It didn't exist in the past, until iOS 6 if I remember correctly - so the only thing you could really do was to turn off iMessage altogether. Nowadays you can just block a number from sending you messages. Thankfully.

I'd imagine he's refering to iMessage on OSX.

Yes ^

The solution seems obvious: if a message is received within 1 second of having received another message from that same user, do not show it, and every time a new message is received, reset the timer.  That would allow all normal messages through but would block messages sent in rapid succession.  It would be fairly easy to program assuming the right tools and controls were available, but it may be difficult or even impossible to actually implement.

This is a denial of service attack.

I think that's just slightly more sophisticated.  Typically is means hitting their network with so much traffic/requests that no legitimate traffic can get in or out.  It sounds to me like OP was just getting spammed with chat messages

Python can't do anything for you here mate.

During a real DOS attack, there is really no script that will help stop it. the most you can hope for is something that will help avoid your own hardware from amplifying the attack. e.g., many web servers will now automatically detect and mitigate many SYN and other low bandwidth attacks. Many consumer levels routers also carry these forms of DOS protection, they do 100% nothing for a packet flood, but they work for more of the low bandwidth stuff, where you can specify limits in packets per second, and various other parameters.

 

For the most basic form of DOS (packet flood), there is not much you can do, as your WAN connection is being saturated.

spamming someone with so many messages that their phone becomes unusable is indeed denial of service.

In computing, a denial-of-service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.

By the very definition you posted you're confirming what I said; it is a term used to refer to when a server is hit with so much traffic it cannot do its job as a server anymore.  I suppose the wording provided could be stretched to include a phone getting lagged out by spam texts, but it's one hell of a stretch imo.

Now those are DOS attacks!   They seem to be talking about sending so many messages in a given area that it completely clogs the network and makes all other texts and even phone calls impossible; a true DOS attack, that just happens to be using SMS messages as the method.  I still feel like the only similarity shared is the fact they and the OP's problem are both texts, but again, are these not a little different than the OP's issue?  It sounds to me like he is just being sent lots of messages.  As in, 1) it's only affecting him, and 2) his phone is still receiving messages, so it's not been completely overloaded - it's just a little annoying.
