TEAM GHOSTSHELL
Project WestWind

Target: 100 top universities across the world

Purpose: To bring attention to the decaying
status of higher education around the world

Outcome: A massive dump of over 120k
student/faculty/staff records pulled from
university servers

The Data: Usernames, passwords, phone
numbers, class numbers, and more
WHO IS TEAM GHOSTSHELL?
Project WestWind
“Hactivists”
focused on
hacking to bring
awareness for
what they
consider to be
the greater good
Team
GhostShell has
made successful
dumps prior to
Project West
Wind
IT Wall Street:
Dumped 50,000
accounts to
support the occupy
Wall Street
movement
Project Dragonfly:
Dumped
200,000 accounts
to support freedom
of speech in
communist
countries


GhostShell was able to take
advantage of vulnerabilities in the
web applications of the targeted
universities to gain access to their
servers
The vulnerabilities were most likely
exploited using SQL injection
The attack took up to four months to
prepare according to Aaron Titus of
Identity Finder (Chief Privacy
Officer)
THE ATTACK!

SQL Injection:
A code injection
technique that
exploits a
security
vulnerability in
a website's
software.

The Damage



Reputation: Anytime
there is a data leak, the
reputation of the
institution is affected
Reputation: GhostShell
also found many of the
machines were already
exploited existing
exploits. Some of these
stored credit card
information.
Cost: Notification and
credit monitoring for
those whose information
was leaked

HOW NOTRE DAME AVOIDED
THE INCIDENT
 Vigilantly
scanning all web
applications using tools such as HP
Webinspect
 Limited
the exposure of public facing
servers with the zone network project
and other efforts across the university
 Luck?
WILL GHOSTSHELL GET CAUGHT?
 It
is unlikely that anyone from team
GhostShell will get caught.
 The
team used TOR (anonymity network) to
extract and dump the data. This allowed
them to mask their location through a
network of anonymous proxies around the
world.

QUESTIONS WE DIDN’T ANSWER

1. List all of the security software the University
licenses


There’s a lot: check the software downloads page for
many approved software packages. If you have a
specific need, drop us a line.
2. Common ePO troubleshooting steps

Rather than talk to the entire room about these, we’ll
schedule an ePO users group meeting.
