Hey,

For those who are interrested, i made two types of Gaara (the calculator virus) disinfectors. The first one patches the virus body, which causes to return the control to the host just when the EPO injection travels the control to the virus. So the virus will not get executed at all. And the second one is trying to find an EPO injection by searching for BRA opcodes, and testing them for suitable conditions.


Here are the codes:

Dis2:

Binary:

i hope you will find them somehow interresting.

best regards,
pb
