The Downside of Friends: Facebook’s Hacking Problem

The Downside of Friends: Facebooks Hacking Problem

You get a quick message from a friend on Facebook, click on the link and
absentmindedly log in to a website pretending to be Facebook. This is what
happened last week, when scammers unleashed a new attack on Facebook,
collecting users’ log-in information and passwords and pilfering victims’
“friends” lists to target the next dopes. Listen up, people: Although
Facebook has a reputation for Internet security — it identified the scam
within hours, and the ripple effects only lasted for a couple days — at
200 million members and counting, the size and popularity of the social-networking site has made it the object of increasing attention from hackers
and spammers. And if last week is any indication, it’s only going to get

“In the ’90s, scammers used e-mail,” says Michael Argast, a security analyst
at Sophos, an antivirus software company. “Today, it’s social networking.”
Argast explains that although people have been trained not to click on
suspicious e-mails, they don’t operate with the same sense of caution when
presented with a link on Facebook or Twitter. Maybe that’s why the number of
phishing attacks on these kinds of sites — in which people are fishing for
account information, as opposed to infecting your computer with a virus — has
skyrocketed recently, from 4,600 attacks in 2007 to 11,000 in
2008. This year doesn’t look any better, with 6,400 attacks in the first
three months of 2009.

Like anything on the Internet, Facebook has never been completely scam-free,
but its privacy settings may create a false sense of security: most users
can’t interact with one another unless they are “friends” or belong to the
same general network. The site at first glance would also seem less of a
gold mine for swindlers since unlike financial websites, which offer access
to victims’ bank accounts, there is no direct financial gain from hacking
into a Facebook account. But the bad guys know that many of us are lazy or
forgetful and use the same password on multiple sites. In early 2008, Facebook noticed a marked increase in the number of scams. “We’re the most
effective distribution platform on the Internet,” says Ryan McGeehan,
the company’s incidence-response manager. “The level of person-to-person
connection doesn’t exist anywhere else. And as we get bigger, we become a
bigger target.”

Facebook monitors users’ activity, and when someone goes from a few wall
posts a week to hundreds of messages within a few minutes, the security team
can logically assume that the account has been hacked. They’ll notify the
user, reset the password, and the whole issue is usually resolved within a
few hours. But when thousands of users are hacked at once — and then
their friends are hacked, and their friends’ friends are hacked — it can
take a few days for Facebook to fix the problem. That’s what happened on
April 29 and 30, when users found themselves accidentally logging in to a
website called Designed to look exactly like Facebook, the
evil doppelgänger took their info and hacked their accounts.

When MarkMonitor, an outside security company employed by Facebook, shut down
the fake website, the scam popped up again on a different site, “My guess is this was a
pretty organized group of people,” says Fred Felman, MarkMonitor’s chief
marketing officer. Felman says the phishers, whoever they were , were not using the most up-to-date
technology, but their creativity and speed makes him think that they have
experience and will probably do it again.

A similar phishing scam established a toehold on the website in January. And
last year hackers broke into accounts by convincing people to click on links
posted on their profile walls. Another common Facebook scam is to hack
someone’s account and then send messages to friends asking for money .

Facebook won’t say how many accounts were compromised last week, but a rep
notes that the site has never had a scammer hack more than a small fraction
of its accounts, adding that the company’s security team — which has more
than 100 analysts, engineers and programmers — can handle whatever comes
their way. “We’re going to be attacked again in the future,” says McGeehan,
“and my role is to be prepared when it happens.”
