Atascadero City, CA


A hacker used a phishing ploy to compromise the computer
system
of
Atascadero, California, and draw $83,000 from city
accounts, the San Luis Obispo Tribune reports.


According to the Tribune, an Atascadero worker
compromised the city's computer security by opening an
email supposedly from the National Automated Clearing
House Association (NACHA) but actually sent by a hacker.
On July 1, three transfers
totaling $83,000 were
sent from the
City's account.

prevent data from being stolen it took 6 days to remove
infections the cost to the City was expected to be in the tens
of thousands. However some monetary costs would be tough
to calculate for the lost productivity.
