``Despite Jeremy Corbyn's assurances that Labour had seen off a DDOS attack, party sources have confirmed a second cyber attack is ongoing.
The Labour website has been working intermittently today, but hackers are using a "bot net" of computers to flood its computers with traffic, trying to take the site offline.``

They're with cloudflare so they'll be fine

Downtime will me minimal

Atlanticism for the win @PureEvilPie

that's what i thought..

Don't you love American styles being injected here?

It's it so great?

Really though, I despise how Americanised we have been

how do you overwhelm cloudflare?

We have our own mini trump actively hiding potential corruption

And no one cares

Amplified DDOS attacks @Crafty

They have many server farms around the world, which they use to load balance, meaning you need to hit them all for the website to go down

Since that amount of data is hard to generate even with a botnet, amplification is required

> This DDoS attack is a reflection-based volumetric distributed denial-of-service (DDoS) attack in which an attacker leverages the functionality of open DNS resolvers in order to overwhelm a target server or network with an amplified amount of traffic, rendering the server and its surrounding infrastructure inaccessible.

You spoof the requester IP address of a DNS request you send to a server, which might only be a couple Kb in size, then the server is able to send say Mb to the spoofed address

Meaning, you can use that botnet to contact other servers to DDOS for you

As they're able to output much more data than you ever could

I can't remember which protocol they abuse

I think it's DNS, not sure though

Ah yeah! I was right

yeah cloudflare have a page on it

Does it show their mitigation?

Yes

``How does Cloudflare mitigate DNS amplification attacks?

With a properly configured firewall and sufficient network capacity (which isn't always easy to come by unless you are the size of Cloudflare), it's trivial to block reflection attacks such as DNS amplification attacks. Although the attack will target a single IP address, our Anycast network will scatter all attack traffic to the point where it is no longer disruptive. Cloudflare is able to use our advantage of scale to distribute the weight of the attack across many Data Centers, balancing the load so that service is never interrupted and the attack never overwhelms the targeted server’s infrastructure. During a recent six month window our DDoS mitigation system "Gatebot" detected 6,329 simple reflection attacks (that's one every 40 minutes), and the network successfully mitigated all of them. Learn more about Cloudflare's advanced DDoS Protection.``

Yeah, they just depend on sheer network capacity and load balancing

> With 30 Tbps of capacity, it can handle any modern distributed attack, including those targeting DNS infrastructure.
😍

they must charge a pretty penny for their service

to make it financially viable

right?

For comparision, the cables running from the UK to the USA have around 30-50 Tbps of capacity each.

I'd imagine so yeah @Crafty

OH

No, it comes as standard

they have data centers in china for their enterprise package

> All Cloudflare plans offer unlimited and unmetered mitigation of distributed denial-of-service (DDoS) attacks, regardless of the size of the attack, at no extra cost.

Fucking powerful.

How long before the Russians get the blame
