Announcements by major companies and Government organizations that they’ve been hacked and have lost millions of private records that we entrusted to them are now as routine as the morning weather forecast on TV news. These announcements are usually followed by an assurance that from now on everything will be just fine, along with an urgent request that everyone change their passwords. Requirements for the passwords are getting more sophisticated – instead of a plain four-letter word they are supposed to be a little longer and include some characters requiring the shift key.

This is totally useless advice for two reasons: one is that these “sophisticated” passwords are in practice just as easy prey for a modern computer as the proverbial four-letter word, and the second is that no real hacker is going after your individual account unless he happens to be your curious next-door teenager or your nosy grandmother. In the real world hackers aren’t dumb. Why would they go after a few million accounts one-by-one if they can simply hack the organization’s server at the root or Administrator level and get all the data in every account with just a single hack? Any hacker worth his salt knows this, and this is exactly what hackers do – they hack the server, and  that makes our individual passwords irrelevant.

These “change-your-password-for-a better-one” announcements likely have some other subliminal agenda. It looks like the real reason for asking you to change your password is to make you feel responsible for your data security. In other words, to blame the victim.

Furthermore, victims are majorly misled in a couple of other ways too. First of all, after a hack all your private personal data are gone, and they’re available to any criminal is cyberspace for a nominal fee. You cannot take them back. You can change your password, but you cannot change your name, date of birth, social security number, address, phone number; even changing your mother’s maiden name is difficult. All these are available to identity thieves.

And there’s another aspect that your favorite bank won’t tell you about: every competent hacker will leave a dormant cyber mole deep inside the hacked system. These are practically impossible to detect despite all political and marketing claims to the contrary. So even if the entire security program of a system is changed the cyber mole will report all the changes to its master. Including your new sophisticated password.

So a hack is forever.
