RE: response to tax software not encrypting tax info Mar 14 2003 08:47PM

Hi,

I have read both of the original advisories, and all of the replies

on this subject, and nobody yet has properly assessed AND

emphasized the actual risk associated with this tax software.

Lots of software programs do not encrypt sensitive data, but what

makes this tax software different, and what increases the

associated risk *substantially*, is that so much of your sensitive

personal and financial information is contained, unencrypted, IN

ONE PLACE. Your full name, address, date of birth, phone number,

social security number, bank account numbers, employment

information, income information, credit card numbers (if making tax

payment with CC), stocks, bonds, other investments, business

information, etc - ALL IN ONE PLACE. If you are married filing

jointly, or have children or dependants on your tax return, then

the personal and financial info for even more people is exposed.

All of the information is guaranteed to be current and correct too.

This is a gold mine for identity thieves. Identity theft is one of

the fastest growing crimes in the US right now too.

Reference: http://www.consumer.gov/idtheft/

Vendors of tax software should not allow users to leave all of this

data in one place unencrypted; the risk is too great.

Note also that other tax software programs not mentioned in the

original advisories are also vulnerable to this issue (thanks for

noting those issues, kjk). I'm not at liberty to discuss those

other tax software packages though.
