I don't see how it is possible to tell a fraudulent paypal payment from a legitimate one, unless the IP address used to make the purchase is all ready known as a source of fraudulent transactions. Obviously if "John Smith" made a payment from an IP address originating from China, Japan or other non-English/American IP address range then something is suspect, but this is still not definitive. How could this system stop a fraudulent payment from a source with an IP address the system has never seen before originating from a corporate address block or respected ISP, or unlikely but not impossible an IP address that has previously made a valid transaction? Any smart fraudster would use a device purchased with cash using a spoofed MAC address from a wifi hotspot out of sight of CCTV. Please enlighten me, or would that let the cat out of the bag? regards mx -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEVAwUBTfDu6bIvn8UFHWSmAQLG1gf9Gv9cpFERJWbxzY05U4Wd6vYxLQb2N4Oy eb8HWYsVALjDO2M3Od9FdXRFCtkF7VHx4hsL67fe69UAqRq3+7yUJEpj+vPMGhow lrb9Nn93R5r14i/dCYJTKQkzQ8zdvkYv3uyvu9A7MP+ME4mukBUTFUyCN2oekr6R fHa7YcjUkB43+IocUjr0EqnVZLtGMbJsFzGXoUNTVpIwPrj5kvTOo4rK8upwaE9g 1V3TRUM815v2hq7IH9IUdu2mAKB9UDNEp8K6Vi6RL0ZMGNWXsf9BL8kmDD/dcOlf 9e2MSN6QQOYeAMYNaZSgOPOjX0sVqhd/fVKEeBMs+OZaOJOfG1Chow== =ytkT -----END PGP SIGNATURE----- _______________________________________________ Full-Disclosure - We believe in it.
