A cluster of Pi offers new hope in decrypting Ransomware. A cluster of 4, Raspberry Pi 4's with 4 Gb of DDR4 memory each !on 15 Sep 2019 Posted by Administrator Category: Security News
Ransomware has become an annoying problem here in Florida and the Southeastern United States. Many small companies and government agencies are not prepared and have no defense against the attacks. They also have no money to get new computers or repair the security problems that let the Ransomware in.
Below are some of the things we are looking at in addition to Decryption Projects as well as how we plan to setup the cluster for maximum efficiency.
1) Already making mods to the original configuration. We found a Windows Utility that will Format an SDCard in FAT 32 up to 2 Tb. (far past the Microsoft limitation of 32Gb) We used the fastest Camera Grade SDCards we could find with 64 Gb each.so a 4 Pi cluster has 256 Gb of Solid State Camera Grade SDCards as its primary Hard Drive.
4) The WiFi and Bluetooth are great but for pure computing strength we will shut them both down and use the Gigabit Ethernet Port. Every un-needed driver, program, or function shut down and removed increases the computing power of the Raspberry Pi 3 and 4.
5) Next we will be shut down devices and functions not used to save computing and electric power. More on that here: https://learn.pi-supply.com/make/how-to-save-power-on-your-raspberry-pi/
6) Then we will setup a RAMdrive and set the software to load the RAMdrive from the SDcard and then booting from the RAMdrive. (Because it is much faster) https://www.domoticz.com/wiki/Setting_up_a_RAM_drive_on_Raspberry_Pi?
7) When the cluster is complete it can be used as a high speed webserver. In fact, the Raspberry Pi manufacturer uses a cluster of Pi's to host their website and support sites. Very heavy, interactive websites with all sorts of multimedia too. https://www.techrepublic.com/article/low-cost-raspberry-pi-4-cluster-hosts-official-pi-website-handles-record-traffic-for-pi-4-launch/
Update for Monday, September 16, 2019
Today we reviewed memory device speed for the Raspberry 4B.
USB 3.0 vs MicroSD Storage
Since Raspberry Pi 4 now comes with two USB 3.0 ports, which support ~100MB/s read/write speed, Connecting a SSD USB 3.0 Drive gets even better speed..
But before you settle on one of those devices check out the transfer speed of the DDR4 on the Raspberry Pi 4.
DDR4 data transfer rate:

The Computer Dudes, Inc. fight Ransomware, Spyware, and Viruses using Virtualization and Advanced Network Designon 08 Sep 2019 Posted by Administrator Category: Security News
Ransomware and other viruses are hitting corporations, government and schools all over Florida and the United States.
Today we had a breakthrough on "Brute Force" password cracking. Our new hardware/software solution can process in less than 15 minutes what use to take it more than 8 hours. The tech can be used for testing passwords or decrypting locked files like "Ransomware."
Coming Soon: A basic guide to dealing with Ransomware.
