Akamai Kicked Journalist Brian Krebs' Site Off Its Servers After He Was Hit By a Record Cyberattack (businessinsider.com)
An anonymous reader writes:Cloud hosting giant Akamai Technologies has dumped journalist Brian Krebs from its servers after his website came under a "record" cyberattack. "It's looking likely that KrebsOnSecurity will be offline for a while," Krebs tweeted Thursday. "Akamai's kicking me off their network tonight." Since Tuesday, Krebs' site has been under sustained distributed denial-of-service (DDoS), a crude method of flooding a website with traffic in order to deny legitimate users from being able to access it. The assault has flooded Krebs' site with more than 620 Gbps per second of traffic -- nearly double what Akamai has seen in the past.
Seems to me the attackers win, at least in the short term, because the caching and CDN provider (who I expect was probably contracted and paid, although it's entirely up to Brian how he handles his business affairs, it does seem likely) takes the site off the air anyway. That being the case ... what's the point of having that contracted relationship, if they dump you anyway?
From Kerbs on Security site:"The attack began around 8 p.m. ET on Sept. 20, and initial reports put it at approximately 665 Gigabits of traffic per second." .
Akami were handling it as of yesterday, but it seems that they decided it was too expensive to stand by their client while he is under attack.
Maybe a coincidence, but this started to happen after Kerbs exposed anti-DDoS 'protection' firm BackConnect use of BGP hijacking.
Akamai has a fiduciary responsibility to others on their network to ensure that they are not impacted by a single user. They were providing the service for free to Brian Krebs, he stated this. I do not work for Akamai(one of their competitors actually) but this is very, very common in this space.
So they booted him off because he was costing them a ton of money and wasn't paying anything. (I guess they were providing him service as a charity?)
But does that mean that they'll kick their paying customers off as well if the costs of defending them against attacks exceed the revenue they're getting from that specific customer? If so that would mean you could put Akamai out of business just by targeting one customer at a time, moving on to a new one as each one was evicted from the service.
This Space Intentionally Left Blank
I don't blame Akamai at all and it sounds like Krebs doesn't either. There were a ridiculous amount of resources used on the attack and that shit gets expensive to block.
Yup. Twice the redundancy per second per second.

Akamai is throwing away a great marketing opportunity and turning it into a huge negative. Why would I move to Akamai, knowing that they'll kick me off their network if I ever have trouble? They're throwing away their primary competitive advantage with one stupid decision.
Blocking DDos is bread and butter basics to a content delivery network, so why are they delivering 620Gbps of data on a DDOS attack?
I would consider it to be good practice, for when a more important customer gets attacked. At the very least I would consider it BAD practice to show that DDos can work easily against an Akamai site.
Akamai need to do an about turn, politely tackle the DDos and sack the idiot that decided they'd fold to a simple distributed denial of service attack.
when you're honest. Krebs doesn't pull his punches and the whiners of the world (i.e. those he lambasted for having low quality products or game play) don't like it and now they're being petulant two year olds.
Just goes to show the mentality of supposed adults. Especially the cowards who sit behind a keyboard and try to destroy the work of others because they didn't get their lollipop.
We will bankrupt ourselves in the vain search for absolute security. -- Dwight D. Eisenhower
The reason that this DDos is able to generate so much force is they aren't just using malware-infected PCs. They are also using security cameras and other devices that connect to the internet. Thanks to all the companies who don't give two shits about securing their devices.
Actually, that's not the case, despite a lot of the coverage claiming it is. It's the largest seen by by Akamai, but OVH reported a DDoS peaking at 800Gb/s earlier the same day - although there are no indications of a connection (yet?). What's perhaps more interesting about the DDoS on Krebs isn't the size of it so much that it apparently wasn't a UDP amplification attack, which is the norm for DDoS these days, but TCP/GRE - the botnet used was generating all that traffic on its own Both attacks are far larger than any one group was thought capable of doing (until now) and might be an indication that the number of botnet operators might not be as large as suspected, but instead consists of a smaller number of operators with multiple botnets under their control.

Recently botnets haven't really been the issue, they've mostly been reflection attacks which use DNS, NTP, etc. to amplify the size of the requests. If networks started to drop UDP packets with spoofed addresses that would reduce the problem significantly (so would convincing a huge number of people to fix their DNS or NTP servers, but that is harder).

How is the Riemann zeta function like Trump rallies? Both have an endless number of trivial zeros.
Where's that Slashdotter from the thread last week who posted 5 easy steps to stopping a DDoS! Akamai needs your "expertise"!
On the gripping hand, this is great publicity for the DDOS service behind the attack
From the right up on it, it was peaking at 665 gigabits/sec and was leveraging a massive botnet trying to make direct connections instead of using DNS reflection. They kept his site up during this and numerous other large scale attacks. Claiming that Akamai isn't a "bullet proof" host because they decided their support cost and impact to their customers outweighed the free-marketing/goodwill is just asinine. You're the same entitled person that uses free web services and then b*tches when they start charging or go under aren't you?
At that size I am sending employees on planes with jackhammers and bobcats to start cutting fibre near the source.
Proper egress filtering by consumer ISPs would stop most of the DNS/NTP/etc amplification attacks overnight. There's absolutely no reason any packets should be leaving, say, Comcast's network with an Akamai source IP on them. But this isn't an amplification attack, at least according to the previous article. This is apparently the old style DDoS, think LOIC, many thousands of hosts making "legitimate" (as far as the TCP transaction is concerned) connections, exhausting resources, sending giant requests, etc.

i would pay akamai to kick off freeloaders so i'm protected. win-win for me. not so much for krebs.
nothing to see here - move along
