I called my ISP and apparently I have a "dynamic IP" because they only give out static IPs on demand, but my IP hasn't changed in months and that's how they keep ddosing me.

if it got compromised months ago and, you were on the same IP since, you have a dynamic, then WTF IS THE PROBLEM.
1. You have a dynamic IP which for sure within that time, you would have a new ip allocated to you. (If it doesn't change, then the ISP is fucking with you)
2. No way you should be getting ddosed. Could be possibly your connection within the ISP. Have you ask your ISP if any faults are occurring on there side because, that could be the case or, get a technician out.
3. and who wants to ddos a person that chills on SL forums. They have no reason to so, looks like you aren't getting ddosed. It has to be your ISP.

As I said many times, I know I'm getting ddosd, I'm 100% sure of this. Just because I'm on the SL forum means I can't get ddosed? I don't see how that has anything to do with each other while I'm obviously active in many other communities. As for my IP, my ISP told me it's dynamic, if they tell me it's a dynamic IP, I don't know what else to say.

Don't forget, people can "bullsh*t". Have you noticed your computer going slow, is it part of a botnet or...?

I would do a fucking clean wipe on all machine and router and, if you're still getting troubles, it's your ISP that you will need to contact. you need to eliminated options till you get your answer. being part of a tech, that's what we had to do to find the issue.

If multiple router reboots and a factory reset doesn't allocate a new dynamic IP (I don't see why It shouldn't), purchase another router and start from scratch- with the Intention of assigning a new IP.

I have a modem with a built in router, so I have no idea how/if to reset that.

Generally speaking, there's a hole at the back of the unit and upon Inserting a paperclip for 5-10 seconds, It will reset the modem/router.

Once you see lights flashing, It will reboot & reset back to It's factory state.

Just did the reset and it didn't change my IP.

It's not a virus and I'm not part of a botnet, I'm getting ddosed and I'm sure of this. my ISP is of no help.

I cannot just purchase a router, I'd have to purchase an entire new modem which would set me back €200, something I'd rather avoid.


RE: getting DDoSed - l33t - 08-05-2018

I can't seem to find the log file Bish0pQ mentioned, I'm looking in my internet administration stuff and I see something "block fragmented ip packets", would this help block the attack possibly?

That's what I meant, your AP- modem/router whatever gateway you access the net.

I'm at a loss as to why your ISP cannot handle It on their end. The traffic (DDoS) Is obviously going through them, yet they're refusing to take responsibility and provide you the service that you signed up for. I'm sure you didn't agree to a DDoS as part of your monthly quota. I'd be speaking to senior management and "demand" they wake up to themselves and get their act together.

@l33t Download Wireshark, look for packets coming in at an unrealistic rate, SOMETIMES they will have a message including but not limited to "A cat is fine too", click one of the packets and look for the IP it's coming from. Then report it to the Cable Company or something.


RE: getting DDoSed - Cryogenica - 08-05-2018

Also, if you can put a linux system (DD-WRT or similar, maybe?) as your router (just behind your modem, nothing in between) you can either set all inbound connections to DROP or limit them to 3 connections per 60 second interval. UFW if good for this if you can get it on your router. Set all outbound connections with UFW to LIMIT (or plain DENY, not REJECT since REJECT rules still send a response), and you should be pretty well off. I did this on my home network and withstood a 40 Gbit/s DDoS attack.

I will demand to speak to a manager the next time I call them, last time I asked to speak to a higher up the lady hung up on me so I hope it'll go better the next time around.

Don't most booters have thousands of different bots that send packets, if 1 gets blocked I'm sure it won't achieve a lot.

Yes, most use many different bots. That's actually the difference between DDoS and DoS (DDoS uses multiple bots, while DoS uses only one).
If, though, you limit them to 3 connections / munite (like I said above), you will notice an initial drop in network speed (assuming the bots come online at exactly the same time, but after a sizable amount of bots get blocked, all you need to do is hold off any new ones that come online to replace the old ones. No bot will send more than 3 connections worth of data, which isn't actually much even for a large botnet, since they get disconnected almost immediately. This basically reduces it from at any given moment a large DDoS attack to maybe a few DoS attacks. And DoS attacks are pretty easy to block.

Yes sadly my ISP doesn't allow for that much customisation with my modem.
