I Am MICHAEL DGREAT..,
I'm a software programmer, in one of my programming, I build a program that generates numbers in sequence.., ,

So I set this program as a side project,.. I believe one day soonest Am gonna get the sequencial order which the network operators prints their recharge cards..... What I needed from anyone willing to help me is that I need a Used recharged cards printed in order or accordingly , of any network,..,
I wanna see If I will be able to get the formula via this used cards you guys are gonna help me find..... I write code all day.., I believe I Can do it....
like three or five cards printed in order.... (INDICATE THE NETWORK TYPE ONLY)

( overlook any misspelled words or Misused words)...
Thanks

Where do you intend getting those. And I don't think network operators will print those cards in sequence: it'd be a big security breach. Then you won't need to buy again. Just get one @ N1,000 and follow the sequence. Since they're sold in pack to the retailers, it follows that every other voucher with the retailer becomes useless. They print it randomly, I think. The can reuse numbers. That's why there's a limit to validity on each of the cards. After that date, the program can regenerate that number for use again.
The hackers/crackers don't know what to go after. They should seek security loopholes in these network operators' systems. Now that's a big work, but it's worth doing. Airtel just reduced the value of their daily blackberry bundles without informing their customers: what a disservice. The unlimited bundle was slashed from 80MB to 40MB, and the rate they charge on data is exorbitant. That's unnecessary profiteering. So attack them.

THE GREAT!

THE GREAT!

THE GREAT!

lol,@ guys mocking the Dud's nick name...

well, @michael the great, wah u saying is valid. it is predictable, no matter how random a number maybe there is a pattern/algorithm from which it originates.

dudes working in some mobile network operators know some loop holes...but it is as u know very unethical.

so, you may keep on searching...av got no help to render in that regard. Thanks.

Thanks So much Sir

YES O

Good luck with getting the algorithm you so much seek after. I tried my own ways too back then but they all just didn't pan out right. You'll outgrow it when you start getting contracts to execute but for now, keep looking to quench that thirst and if you eventually do, pm me

What's the purpose of this? Project eular is available for u to test your skills, use it or innovate on an already existing idea.

My dear great,

Sorry to dissapoint you but you are wasting your time. You will not crack the PIN of those recharge cards. You could potentially get 1 password hit but to get the PIN generation process is simply you wasting your time.

I used to work as an R&D Engineer in 1 of the Telecom Software Vendor that sells the software which generates the PINS for the Telco Operators and I understand a fair bit about the internals of these systems.

The algorithm that generates the PINs are actually quite popular.. A combination of MD5 and pseudo-random Number generation.

Typically this would not be very hard to cause a collision( if you had a super-computer and excellent programming skills, both which I doubt you have), but the telecom network tend to be strong on Network Security and the Software Systems tend to ensure that certain measures( locking you out after 3 failed attempts etc) to ensure that a sheer Brute force attack is simply not feasible.

You can keep trying but I am quite certain that you would be wasting your time.

My apologies

^^^above poster is right.

Nobody in his right sense would generate business-critical public pins/codes without a measure of cryptography


The first line of defense is your key generation. It involves measurable PRNG(Pseudo-Random Number Generator) passes.
There is a whole lot of Ph.D skills required.

This diminishes the likelihood of ever reverse- engineering generated keys to reproduce the generator(s).

The second is to frustrate anyone from doing it. ...limited phone lines... Limited tries.
Even if you have 10,000 lines, 3 tries each = 30,000 tries wouldn't be enough sample space.

Secondly, our PCs aren't suitable for Cracking.
Even a 64GB RAM, Octacore CPU can't even do much in cracking high bit cryptos...

Now, that's one good use of a Super Computer! .... Every country could use one as a defense and cracking machine. They are so powerful enough to break commercial grade cryptographic setup within minutes.

I hope I made little sense....

dudes, no matter how strong a security or firewall may be, hackers look out for loop holes.. Come on, even street boys do lots hacking on these mobile operators servers.. this comes from prediction and studies...for example picking a time when there is gonna be routine maintenance, temporary shut down of servers... just anything can come handy n put the whole shiit in mess...

we have witnessed big systems fail in the past due to hackers crawl.

.. Hackers r invited to come test systems even after the best security dudes av finished works on it..I know of Glo..am sure others would pass through such process too..this is done to tighten loop holes that could only be seen by an external person who wasn't present when the system was designed...

avnt u wondered why some lay guy will just be looking at ur finished work and just type in some funny thing, and that exposed a whole lot of holes that he may not understand., but you r just okay cos ur algorithm is in place...naaah!


it could be as little as guesses, social engineering, psychology etc...and of course insider info..

in conclusion , it is unethical...and I don't associate with it..

You can't write proper English plain and simple, don't excuse your ignorance by making spurious claims. But it'd seem you still have a chance to make amends so I hope you take it. Believe me, unless you are living in a none English speaking country, you desperately need sound English grammar. Job aptitude tests mostly consist of tests of your verbal and quantitative reasoning, and your poor grammar is surely a minus at job interviews.

Back to software development, a thorough understanding of the software requirements document (SRS) is key to designing and implementing a solution that will meet the client's needs. Internal project reviews with other developers, Business Analysts and Project Managers are also a normal part of software development process and all these require a good grasp of the language in which they are undertaken. So, if you desire to be a well rounded professional never take any part of your training for granted.

That was harsh sir...

SRS, you mean software requirement specification..ok, I can relate to that.
