Exactly why there is no such thing as fool proof security when it comes to cyber.
The real problem with security is TIME, plenty of hackers out there harvest and archive data that was transmitted though the net, of course they are encrypted but the encrypted life cycle is much shorter than many would thought.
The secret to hack in data is collecting data and wait for security flaws announcement, the hacker would downgraded their OS or application version to the one with security flaw, then used it to crack in encrypted data file BAM! Clear as whistle, all data showed up and that includes your SSN with address and because it has history so history questionnaire from creditor can be answered right there thinking its legitimate where it is really a crooked.
Best security is NEVER transmit over the net, unplug Ethernet cable and disable WiFi and other wireless shyt. But because of today technology, it seems impossible.
