Re: DDoS attack with blackmail

Jim,

While I don't envy those who put in long hours to mitigate DDoSes at the
11th hour, the security industry as a whole, DDoS mitigation included,
doesn't have a perfectly clean track record. Public court records offer
plenty of evidence, and convictions from foul play while trying to win bids.

An individual I worked with previously personally handled a long, drawn out
DDoS event that was ultimately perpetrated by a security contractor bidding
for a job (I didn't work it personally, but it was a frequent topic of
discussion while it was ongoing). Fortunately, after subsequent months of
law enforcement investigation, the contractor was brought up on charges.

It's definitely not "crap" , it's a fact, albeit not necessarily common.

While I have no design to engage in over email argument over how much
latency people can actually tolerate, I will simply state that most people
have a very poor understanding of it and how much additional latency is
really introduced by DDoS mitigation.

As for implying that DDoS mitigation companies are complicit or involved
in attacks, while not the first time i heard that crap it's pretty
offensive to those that work long hours for years dealing with the
garbage.  If you honestly believe anyone your dealing with is involved with
launching attacks you clearly have not done your research into potential
partners.

Some industries can’t afford that extra delay by DDoS mitigation vendors.



The video game industry is one of them and there might be others that
can’t tolerate these extra ms. Telemedicine, video-conference, fintech, etc.



As a side note, my former employer in video game was bidding for these
vendors offering DDoS protection. While bidding, we were hit with abnormal
patterns. As soon as we chose one vendors those very tricky DDoS patterns
stopped.

I am not saying they are working on both side, but still the coincidence
was interesting. In the end, we never used them because they were not able
to perfectly block the threat without impacting all the others projects.



I think these mitigators are nice to have as a very last resort. I
believe what is more important for Network Operators is: to be aware of
this, to be able to detect it, mitigate it and/or minimize the impact. It’s
like magic, where did that rabbit go?



The art of war taught me everything there is to know about DDoS attacks
even if it was written some 2500 years ago.



I suspect that the attack that impacted Baldur’s assets was a very easy
DDoS to detect and block, but can’t confirm.



@Baldur: do you care to share some metrics?

I also recommend book Art of War from Sun Tzu.



All the answers to your questions are in that book.

20 years ago I wrote an automatic teardrop attack.  If your IP spammed us
5 times, then a script would run, knocking the remote host off the internet
entirely.



Later I modified it to launch 1000 teardrop attacks/second…



Today,  contact the FBI.



And get a mitigation service above your borders if you can.

Hello



We got attacked by a group that calls themselves "Fancy Lazarus". They
want payment in BC to not attack us again. The attack was a volume attack
to our DNS and URL fetch from our webserver.



I am interested in any experience in fighting back against these guys.



Thanks,



Baldur
