(A long time ago I made such a LiveCD that ran Aliqueit and all its factoring programs. This should be similar.)

I have been playing around to see what I can and can't do with a live linux DVD against an infected Windows system. I've found lots of "challenges," but this approach may be workable. At this point, I am pursuing this mostly as an educational tool, but would like to know if there is perceived to be any practical interest. I plan on following this project for a while, but if there is no interest, I may not proceed past any real sticking points. My basic scheme presently, is to build a Live-DVD with Xubuntu OS which works in the following manner: Code: 1. Boot infected machine from DVD (Xubuntu) 2. Follow script file throughout the procedure, which a. creates a temporary drive under C:\Users, possibly called teslatemp b. finds a .pdf.vvv file as an example infection and copies that file into teslatemp c. runs TeslaCrypt to extract pre-key composites d. translates composite(s) from hexadecimal to decimal e. checks composite(s) against factordb.com by treating it as an aliquot sequence (1) if factored, returns all factors and branches to 3, below (2) if unfactored proceeds with f, below f. uses installed Aliqueit/ecm/msieve/ggnfs/+ packages to factor composite(s) (working files and relations would be stored in C:/Users/teslatemp) g. submits factors to factordb.com for retention 3. presents factors for use by TeslaCrack ** It is also possible, I will develop this into a GUI application, but that might be a ways off ** Beyond the obvious (always present) possibility of trashing the Windows system, is there anything that I can't stumble into a way of doing, due to my ignorance of an in-built block? Thank you for any and all comments, pro or con...

Ironically, some people may see this as even more complicated than running factoring programs manually ("Linux DVD? That sounds scary!") But for educational purposes then there is really no problem.
