Layer7 Attack - WordPress Pingback

Today we had another Layer7 attack, we'd like to apologize for the downtime as that's never fun for anyone.
Our front-end was down for about an hour.

For those wanting more info about the attack, read below.

The attacker used a vulnerability in WordPress's XML-RPC Pingback that allows the attacker to use this functionality to initiate a "pingback" request from a WordPress installation to a target, in this case it was our website.
Incapsula has an interesting article on this matter and I suggest you read through it if you're interested.

We had a total of 30,769 IP addresses (WordPress installations) constantly sending requests to our front-end for an hour.
The database couldn't handle the amount of requests it was getting (over 2,000 requests per second) so we had to simply turn the web server off until the attack stopped.

Here's a visualization of the web server log when it was under attack:

What's more interesting is what WordPress versions each WordPress installation was running.

Here's an example of a line in our web server log, we can extract the WordPress version and the URL of the WordPress installation from this: - - [15/Apr/2014:13:56:46 -0400] "GET / HTTP/1.0" 200 49190 "-" "WordPress/3.4.2; http://affinitiitv.com" "-"

Top 10 WordPress Versions
  1. 3.8.3: 6,608 requests
  2. 3.5.1: 3,743 requests
  3. 3.6.1: 1,915 requests
  4. 3.8.1: 1,738 requests
  5. 3.4.2: 1,540 requests
  6. 3.6: 1,520 requests
  7. 3.7.3: 1,460 requests
  8. 3.5.2: 1,377 requests
  9. 3.7.1: 1,160 requests
  10. 3.8: 1,148 requests

We compiled together a list of the WordPress installations, so feel free to look through the list to check if your WordPress installation was used.

Pool Bonuses have ended

We have set the Bonus back to 0% and will be running 0% Fees for 3 more days.

UPDATE: Fees have been set back to 1%

Pool Bonus and Lost Balances Update

We have set the Pool Bonus (Negative-Fee) back to 2% as our dogecoin wallets are running thin.
We want to thank everyone that joined us in the past week and also everyone that's been with us this whole time. 
We will be running this 2% bonus until April 10th 0:00 MST, there will be no Fees for 3 days and afterwards our Regular Fee of 1% will be in effect.

As for the lost balances, we have finished calculating one of the stratum servers and have found an efficient way to scrape the logs on the other two, we expect payments to be credited today!


We have finished the calculation of the missing dogecoins and shares and here are the results:
  • Total amount of missing shares: 990,638
  • Total amount of unpaid DOGE: 119226.58625649

Formal Apology to our miners

I'm sure most of you shibes have seen a lot dogecoin pool get DDOS and DoS attacks recently. An example is when teamdoge got attacked for over 12 hours

Rapidhash also received several attacks. We had an attack on our Stratum Servers which we were easily able to mitigate and an attack on our Frontend which produced a very undesirable effect.

When our Frontend got attacked it disconnected one of our Stratum Servers. That Stratum Server was unable to insert submitted shares on our database, therefore not giving credit to some shibes that were mining.

We have logs of the Shares submitted and we are compiling a list of how many shares did not get inserted for our workers.

In order to make up for this we have increased our Negative Fee to 5% and are compiling the missed Payouts to our users which we will send out hopefully by the end of today.

We at RapidHash hold ourselves to a high standard and with that would like to sincerely apologize to the shibes that were affected by this.

DDOS Attacks

We had a Layer7 attack on our Frontend Web Server, the attack has been mitigated. We apologize for the inconvenience.

Restart your miner if your dashboard hashrate shows up as 0 KH/s.

EU Stratum is up and running!

Being the most popular request we have finally provisioned a stratum server in France for you French and European Shibes. This new server is unlike the one in the US as it uses new software, so we recommend that you set a failover in cgminer/sgminer just in case.

The details for the new server are eu.rapidhash.net with port 3333

Pool Wallet Upgrades Completed

We have finished upgrading our pool to the Dogecoin 1.6 Wallet. We suggest you upgrade as soon as possible.

Here is the link to download the new wallet: https://github.com/dogecoin/dogecoin/releases/tag/1.6

Update highlights:

  • No longer a random block reward - we now only have static blocks. The current reward will be 250,000 Doge per block, with the halvening dropping us to 125,000 Doge per block, etc etc. This will prevent block cherry-picking; as we're seeing at the moment, with our community pools only seeing 100-200k blocks, while the multi's gaming the system are enjoying 300-500k blocks. From the 1.6 update, all blocks will be completely even.
  • The DigiShield difficulty algorithm: again, developed and contributed by the very clever folks at reddit.com/r/DigiByte , this allows for rapid block retarget times, and rapid recovery from multipools suddenly hitting the network; meaning that our miners will no longer suffer from extremely long block times if a Multipool does decide to jump on board. This new algorithm will retarget our block times much faster - ensuring the hard-mining shibe is not left holding the bag after the multipool ransack.
  • Coins mined must mature for 4 hours (previously 30 minutes) before being spent. This is a precautionary measure, to give everyone more time to communicate following any future fork of the network.

Negative Fees Have officially ended

For those of you that recently joined us we would like to thank you! With that said we are ending the Negative Fees Promotion. Pool fee will be be 0% until 3/10/2014. After that the Pool Fee will be set back to 1%

Negative Fees Update

We have set the fees to negative 1% in order to run this promotion longer! Tell all your friends about us!

Negative Fees Have been Turned on Once Again

Since we've had a bit of downtime recently We thought that we should reward our loyal miners with a Negative 2% Fee for a couple of days. That's right, you will earn 100% without fees and then we will add 2% from our pocket. We are literally PAYING YOU out of our pocket to mine with us!

Here's how it will work, in the past for your payouts we have inserted a "Credit" and a "Fee" Transaction like this:

The method we'll be using for Negative Fees will be by making the "Fee" a "Bonus" Transaction like this:

This way you'll be able to see how much extra doge you doge you earned by mining on our pool :D

Frontend Theme Changes

We've updated the Pool Website Theme. Tell us if you have any recommendations via the Live Chat!

Negative Fees have ended.

We have run out of funds for the Negative Fee promotion and unfortunately have to end it. We'd like to thanks everyone that is mining on our pool along with every single shibe that joined us in the past few days.

Fees have been set back to the regular 1%, this fee helps us cover the expenses of our servers, DDOS Protection and CDN service.

Negative Fees have been turned on!

We have have turned on a negative 2% fee for everyone on the pool. During the duration of this you will be paid an extra 2% of whatever you mine on top of your block reward.

This is obviously very costly. If any of you could donate for the duration of this that would be great!


Front-end has been updated!

We have updated the pool, username logins will no longer work due to security reasons. Use your email address to login.

Also, any changes to your account will now require you to unlock your account via email and click the link inside.

EDIT: You can now enable login notification emails in the notification area as well.


I want to thank each and every one of you for mining on our pool. You've helped us reach 300MH/s and have helped build an amazing IRC community.

To redeem your prize please pm rog1121 on reddit with your pool API key and an address he can send your prize to.

Infastructure Updates

We've added a failover stratum Server, anyone in the EU should use stratum2.rapidhash.net. Its located in Amsterdam.

Here is a new and updated cgminer command you should use for optimal settings.

cgminer --scrypt -I 13 --no-submit-stale -o stratum+tcp://stratum.rapidhash.net:3333 -u Weblogin.Worker -p Worker-password --failover-only -o stratum+tcp://stratum2.rapidhash.net:3333 -u Weblogin.Worker -p Worker-password

Wow such Dashboard

We've done an overhaul on the dashboard interface and widgets, enjoy!

Wallet v1.4 released

Make sure you upgrade your dogewallet to v1.4. Not doing so can cause you not to see your latest transactions.

Such Growth, Many Blocks, Very Rapid

The Rapid-hash team wants to thanks everyone who is mining on our pool. You've exceeded our expectations and have generated quite a lot of doge for the dogewallet.com victims. As everyone knows pool growth is important for it to stay alive, so please try to tell everyone you can about the pool. It will benefit everyone in the end and if we continue to grow we could get about half of the doge back to the dogewallet.com users.

Happy Holidays everyone!

Congrats On The First BLOCK!!

The first block had an error and we will sending payouts manually. Make sure you have an address listed on your account.

EDIT: We added the doge on here. Everything has been fixed. Enjoy!

Thank you,

RapidHash team
