Scammers Use New Phishing Strategy To Steal Your Passwords

by | September 8, 2021 | Cybersecurity News

Pay close attention to email links, because they might not send you where you expect. Attackers found a new phishing strategy to steal your credentials.

New Phishing Strategy Renders Known Security Practice Obsolete

A classic and almost famous internet security practice just bit the dust. For decades, email users were advised to hover their mouse over a URL to see where it led. You were good to go if you saw the link to a legitimate website.

However, on Tuesday, Microsoft disclosed details on a new phishing strategy: phishing emails containing malicious links disguised as URLs to reputable sites. The links redirect victims to a credential-stealing page.

How It Works

This approach relies on a type of link used by marketers to gather information about who clicks on a URL in a newsletter or on social media. Known as open redirector links, the structure of the link begins with a primary domain, followed by a string of analytics data and a destination website.

Microsoft has been actively tracking a widespread credential phishing campaign using open redirector links. Attackers combine these links with social engineering baits that impersonate well-known productivity tools and services to lure users into clicking. Doing so leads to a series of redirections—including a CAPTCHA verification page that adds a sense of legitimacy and attempts to evade some automated analysis systems—before taking the user to a fake sign-in page. This ultimately leads to credential compromise, which opens the user and their organization to other attacks,” according to a post on its security blog.

According to Microsoft, this phishing strategy uses open redirects to take advantage of an average user’s security awareness training.

Adding to its complexity, the new campaign uses captchas to inspire a sense of authenticity to its targets. Unsuspecting users who believe they’re on a legitimate site will enter their login credentials thinking they’re accessing a notification, report, or even a Zoom meeting. Unfortunately, they could not be more wrong, as the fake error page displayed prompts a second entry of login credentials only to steal them.

After the phishing attempt has successfully stolen the user’s credentials, they will be redirected to another genuine website.

“This phishing campaign is also notable for its use of a wide variety of domains for its sender infrastructure—another attempt to evade detection. These include free email domains from numerous country code top-level domains (ccTLDs), compromised legitimate domains, and attacker-owned domain generated algorithm (DGA) domains. As of this writing, we have observed at least 350 unique phishing domains used for this campaign. This not only shows the scale with which this attack is being conducted, but it also demonstrates how much the attackers are investing in it, indicating potentially significant payoffs,” Microsoft said.

Microsoft warned about a new credential-stealing phishing strategy.
