Is Your Online Bank Vulnerable To Currency Rounding Attacks?
- mcherm 15y agoTricks like this are why the bank that I work for does monitoring of transaction behavior. Although we don't have this particular vulnerability, imagine that we did. For the first day (or at least the first few hours) the customer would perform the massive number of 1-cent currency conversions, making some money in the process. Then our security department would investigate the anomalously high number of transactions, would see what the person was doing, and would stop it immediately. Any system (not just a bank) needs computerized processes to handle huge volumes of processing, but also needs human overseers who can recognize anomalous patterns, investigate and correct. Put differently, you can fool some of the computers all of the time, whereas humans can quite easily be fooled some of the time but are rather resistant to being fooled all of the time.
