SANS Report On Identity Theft and Attacks On Computer Users

OUCH: The Report On Identity Theft and Attacks On Computer Users
Volume 1, No. 9.                                       September 8, 2004

Major threat this month: Phishing attacks that seem to come from
Citibank, Paypal, Citizens Bank and US Bank

Phishing attacks have been doubling every month. In a phishing attack,
the thieves pretend to be sending you to a reputable site like Citibank
and ask for your private data, so they can steal your money or your
identity. Recent research reports that one in twenty people are fooled
by these types of attacks, which is why the thieves keep at it.  One of
our goals is to make sure you don't get caught in the scams.

Also this month, graphical spam is increasing. Spammers send you a
picture of the offer instead of the text of the offer, so that your
company or internet provider's spam blockers are powerless to stop them
even if they use very bad language.

The attacks discussed here are the tip of the iceberg.

To be safe:
   1. DON'T open email attachments from anyone unless you know the
       sender and you were expecting the attachment.
   2. DON'T click on links in emails or web sites unless you can
       guarantee the email came from someone who is not trying to fool
       you and that the web site is actually the site you think it is.
   3. DON'T disclose private information unless you initiated the need
       to do so.

What To Avoid This Month

I. Emails from people trying to get you to divulge private details.
These are often trying to steal your identity (and your money)
   I.1 Maintenance Update (from Citibank)
   I.2 PayPal account limited
   I.3 Citizens Bank Fraud Verification Process
   I.4 Citibank with various subjects and possibly a time stamp
   I.5 Attn: Citibank Update
   I.6 "notice: US Bank"

II. Opening attachments that have interesting subjects and provocative
text in the body of the email.  Several viruses (Beagle, MyDoom, Netsky)
are still spreading rapidly because they fool you into thinking they
come from a friend and have data you want to see. Remember: do not open
unexpected attachments without checking with the sender to be sure the
attachment is safe. If you break this rule, you will hurt a lot of other
people - people you know - because your infected computer will send
viruses to people in your address book.
