Smelling #Korean technical bullshit when I see it!

The recent cyber attacks on South Korea’s banks has made quite a stir in the media.  3 banks services were unavailable  for many hours with lingering effects still.  Yet when I see a line that supposedly explains the origins, and that line is total and utter bullshit….well, I’m gonna call it.


See,  they track who is attacking by IP address.  Sure it probably will not be a North Korea IP address and like many other types of attacks, such methods use systems in other places, countries.  So they originally blamed the attacked coming from a Chinese IP address.  Not surprising really, happens all the time.  In fact, there are certain services that blanket-block any/all Asian IPs because of things like this.  What really got me is the line where they played on people’s absolute ignorance of how networking works.


The IP address was used only for the company’s internal network and was identical to a public Chinese address.


There is a severe problem with this statement.  This situation is completely and utterly impossible to happen.  Out of all the original IP(version 4) addresses, 3 ranges are used exclusively to internal networking.  These 3 ranges are not ‘routable’, meaning you cannot use them to access the internet.


However, they cannot have IP connectivity to any host outside of the enterprise.
source - RFC1918


So, tell me. How can an internet network IP address possibly be the same as an IP address on some external network in China?  That’s right, it can’t.  Thus I call bullshit.


Still want to believe everything you read in your newspapers?

Having a love of travel has lead me to move to South Korea in 2010. Moving to an Eastern culture from a Western culture is a wild experience and there is never a dull day!

    1. Like any other ‘attack’ you have to look at who stands the gain the most from such events. Sure it is easy to blame North Korea, especially given all the media hype and amusing propaganda videos that have surfaced as of late but this also is a great time for some unknown force to take advantage of the situation to easily deflect any suspicion from them. Take the Chaebol( that operates here. If someone needed some sort of financial leverage then staging an attack would be a good way to cover their ass. Sadly, I am not in an inner-circle of confidents and thus only have the information fed to the public like anyone else. Who actually did it? We’ll probably never know.
