Credit Card Visa Hack Ucam
Hi Guys.In My previous post i give you Hacker's Black Book: Important Hacking and Security Free Download.Now Today i give you intrusting and most helpful in credit card hacking ebook.With the help of this ebook you can secure your credit card banks accounts and security.Automatic Teller Machines (A TMs) are used by
millions of customers every day to make
cash withdrawals from their accounts. However, the wide deployment and
sometimes
secluded locations of ATMs make them ideal tools for criminals to turn
traceable electronic
money into clean cash.
The customer PIN is the primary security measure against fraud; forgery
of the magnetic stripe on cards is trivial in comparison to PIN
acquisition. A street criminal can
easily steal a cash card, but unless he observes the customer enter the
PIN at an ATM,
he can only have three guesses to match against a possible 10,000 PINs
and would rarely
strike it lucky.
Even when successful, his theft still cannot exceed the daily withdrawal limit of around $300 . However, bank programmers have access to the computer systems tasked with the secure storage of PINs, which normally consist of a mainframe connected to a \Hardware Security Module" (HSM) which is tamper-resistant and has a restricted API such that it will only respond to with a YES/NO answer to a customer's guess. A crude method of attack is for a corrupt bank programmer to write a program that tries all PINs for a particular account, and with average luck this would require about 5000 transactions to discover each PIN. A typical HSM can check maybe 60 trial PINs per second in addition to its normal load, thus a corrupt employee executing the program during a 30 minute lunch break could only make o with about 25 PINs
