DoS vs DDoS – why “D” make difference here

2012.09.25

It’s all started from my Granma (R.I.P.)

Anyway, since Brian Krebs make those mistakes, I have to write this ๐Ÿ™‚ At least, for my lovely Granny (both of them)

Well – DoS is denial of service attack – it’s not just end-up with massive packet flood, even if Wiki say so in first sentence. It require tech skills and knowledge to by one computer cause local or remote Denial of Service to service\daemon. If You doubt it – have a look at http://www.exploit-db.com/dos/ – all this DoS exploits. If Yor Granma can do this, I want to read her blog – she is fabulous lady then! ๐Ÿ™‚

And Yes, for now causing DDoS is usually pressing F5 in browser or sending huge ping-s to server. Or LOIC\HOIC – as press-one-button solution for less sophisticated Granmas, in case there are many of them You can aggregate ๐Ÿ™‚

Sorry for being bit sarcastic – but it cold outside and late ๐Ÿ™‚

See Ya

Do You need a laptop to be a hacker?

2012.06.20

Hacker is more way of life than IT knowledge and tech skills. ๐Ÿ™‚
Obvious? Sure, all truth is obvious. But this is not what I was talking about.

There is an oldย  Russian joke about how to hack an ATM:

– To hack an ATM, You need a sledgehammer, black mask and laptop. You wear mask, and smash ATM with sledgehammer till it totally broken, than take money and leave.

– And what laptop for?

– What kind of hacker You are without laptop?!!

Well, actually You are ๐Ÿ™‚ And here is morning story:

We have few building with complicated system of elevators. Each buildingย  have separate “smart management” system for elevators management, there at least 2 different systems present, and each of them make a noticeable mistakes for frequent elevator users.

So, I am standing in lobby, no going up elevators, all of them up, only one is empty and going down. “What the hell” – I think, – “lets go down and then up”. I am getting in and prepare to wait. At last second man jump-in the elevator, about 50, says:ย  “Hi! Up or down?”. “Up” – I say, – “but elevator goes down first”.

So, he step on the way of the elevator closing door, and begin to rapidly press button of upper level he needs. Elevator make a try to close door, then again, then short “beep” and arrow “Down” change with arrow “Up” and we going up…

“Don’t forget to press a button”- he said.

“Nice trick, good knowledge of computers, some system bag?” – I am sure guy is somehow related to elevator systems.
“What? No! Just with this stupid elevators You have to take an control in Your hands, otherwise You will never arrive in time” – he said. – “In the [other building] this trick not working, but there is a way too…”, – and he explains me how to stop elevator in other building…

“See You around! come to visit us at [salesmen company name]!” and he left on his level.

And now I am typing this, because apparently joke should be rewritten – You don’t need a laptop to be a hacker ๐Ÿ™‚
