Deepwater Horizon, Siemens PLC and Stuxnet

Stuxnet may have missed its target and may have caused other damage. Read F-Secure's Q&A regarding use of Siemens PLC in Deepwater Horizon.

Simple "Hello World" Using Grand Central Dispatch ( BSD , OS-X )

Simple piece of GCD code:

#include "stdio.h"
#include <dispatch/dispatch.h>
#include <Block.h>

int main()

dispatch_queue_t dq;

dq = dispatch_queue_create("HelloWorld", NULL);

dispatch_block_t block = ^{printf("===========Hello world.\n");};



return 0;

Shtting Down Stuxnet in Infected Systems

A possible approach to remove Stuxnet is to create an anti-body superior in its "resilience" in comparison to the Stuxnet malware itself.

The anti-body should be just as "infective" if not more, i.e. it must be possible to have it installed in all relevant systems on the network, in a manner similar to Stuxnet itself.

Spreading like a manner similar to Stuxnet itself, and possiblly in a more viral manner, the anti-bodies will disable Stuxnet for garbage collection.

This seems like the best approach to me when it comes to super-infections. At least that's how it happens in our bodies.

Iran has made some interesting advances in drug invention and production.

I will not be surprised to see Iran become a leader or a leading partner in the production of cyber anti-bodies that work against malware from cyber criminals.

By the way, my conjecture is that those who created the Stuxnet -- whose operations are essentially akin to biological warfare -- have most probably also created some anti-bodies.

Of course, there's an art in creating anti-bodies and in immunology.

That same art needs to be applied here.
