Half of all Phishing Sites Now Have the Padlock

Maybe you were once advised to “look for the padlock” as a means of telling legitimate e-commerce sites from phishing or malware traps. Unfortunately, this has never been more useless advice. New research indicates that half of all phishing scams are now hosted on Web sites whose Internet address includes the padlock and begins with “https://”.

Recent data from anti-phishing company PhishLabs shows that 49 percent of all phishing sites in the third quarter of 2018 bore the padlock security icon next to the phishing site domain name as displayed in a browser address bar. That’s up from 25 percent just one year ago, and from 35 percent in the second quarter of 2018.

This alarming shift is notable because a majority of Internet users have taken the age-old “look for the lock” advice to heart, and still associate the lock icon with legitimate sites. A PhishLabs survey conducted last year found more than 80% of respondents believed the green lock indicated a website was either legitimate and/or safe.

In reality, the https:// part of the address (also called “Secure Sockets Layer” or SSL) merely signifies the data being transmitted back and forth between your browser and the site is encrypted and can’t be read by third parties. The presence of the padlock does not mean the site is legitimate, nor is it any proof the site has been security-hardened against intrusion from hackers.

Most of the battle to combat cybercrime involves defenders responding to offensive moves made by attackers. But the rapidly increasing adoption of SSL by phishers is a good example in which fraudsters are taking their cue from legitimate sites.

“PhishLabs believes that this can be attributed to both the continued use of SSL certificates by phishers who register their own domain names and create certificates for them, as well as a general increase in SSL due to the Google Chrome browser now displaying ‘Not secure’ for web sites that do not use SSL,” said John LaCour, chief technology officer for the company. “The bottom line is that the presence or lack of SSL doesn’t tell you anything about a site’s legitimacy.”

The major Web browser makers work with a number of security organizations to index and block new phishing sites, often serving bright red warning pages that flag the page of a phishing scam and seek to discourage people from visiting the sites. But not all phishing scams get flagged so quickly.

I spent a few minutes browsing phishtank.com for phishing sites that use SSL, and found this cleverly crafted page that attempts to phish credentials from users of Bibox, a cryptocurrency exchange. Click the image below and see if you can spot what’s going on with this Web address:

Teach a Man to Phish…

Phishing may not be the most sophisticated form of cyber crime, but it can be a lucrative trade for those who decide to make it their day jobs. Indeed, data secretly collected from an international phishing operation over  18 months suggests that criminals who pursue a career in phishing can reap millions of dollars a year, even if they only manage to snag just a few victims per scam.

Phishers often set up their fraudulent sites using ready-made “phish kits” — collections of HTML, text and images that mimic the content found at major banks and e-commerce sites. Typically, phishers stitch the kits into the fabric of hacked, legitimate sites, which they then outfit with a “backdoor” that allows them to get back into the site at any time.

About a year and a half ago, investigators at Charleston, S.C. based PhishLabs found that one particular backdoor that showed up time and again in phishing attacks referenced an image at a domain name that was about to expire. When that domain finally came up for grabs, PhishLabs registered it, hoping that they could use it to keep tabs on new phishing sites being set up with the same kit.

The trick worked: PhishLabs collected data on visits to the site for roughly 15 months, and tracked some 1,767 Web sites that were hacked and seeded with the phishing kit that tried to pull content from the domain that PhishLabs had scooped up.

PhishLabs  determined that most of the phishing sites were likely set up by a single person — a man in Lagos, Nigeria that PhishLabs estimates was responsible for about 1,100 of the phishing sites the company tracked over the 15 month experiment.
