Google takes aim at imposter websites with new Chrome
warning
Because most people don't notice when they're at the
wrong website.

Now, Google
wants to call them out.
To do that, the company is developing a new warning in
its Chrome browser that appears when you're visiting a site that's mimicking a
well-known web page. The warning could ask you, for example, if you actually
meant to go to "paypal.com" when you were headed to a lookalike scam
site called "paypa1.com" instead.
The warning is intended to take the pressure off you
to notice when something's wrong with the URL. That's important because most
people don't notice when they're headed off to a scam site, Google Chrome
engineer Emily Stark said in a talk on Tuesday at the Enigma Conference, a
security and privacy event.
"What people are seeing in the URL bar really
just isn't helpful to them as a security mechanism," Stark said.
The warning could help make it harder to carry out on
one of the most pervasive and effective hacking attacks out there -- phishing.
If users heed Chrome warnings, it could save them from entering usernames,
passwords or credit card informationinto websites controlled by criminals. It could also
keep them from downloading malicious software at scam websites that could do
things like encrypt
their data and demand a ransom.
Scammy websites use a number of tricks to look legitimate
in that URL field at the top of your web browser. They might use a slight
misspelling, or swap out the number one for a lowercase letter L to look like a
legitimate website. The latter is called a homograph attack, and it's powerful
because it usually involves characters that the untrained eye will miss.
The new warning, which is still being tested, alerts
users to the fact that they aren't heading to a popular website or a website
they've engaged with in the past. If the user wants to keep going in that
direction, they can click "ignore." Stark said her team wanted to
throw up a flag for users without overselling the danger.
"We designed this warning to be informational
rather than scary," she said.
The talk follows comments
Chrome security experts made in September about security problems involving URLs. At the
time, Google said its engineers were researching how to make changes to the way
Chrome handles URLs in order to improve safety.
On Tuesday, Stark said changes Google and other
software developers propose should be "incremental." Still, no idea
is too crazy to at least consider, she said.
"Website identity is so, so broken that all ideas
should be on the table," Stark said.
