Threats can be hard to spot. When you’re not on the lookout for what might be the entrypoint for a data breach, you’re more likely to miss it. And oftentimes, threat actors are good at reaching you when you’re vulnerable—and when you’re expecting something.
In this post, I’ll paint you a picture using a recent threat we discovered.
A Normal Day:
So you’re working on closing a large contract with a company, and you expect to hear back from them shortly. Suddenly, you get a ping as a new email enters your inbox. You tab over from the latest and greatest trends in dog-based TikToks to see what should be the email you’ve been expecting. You click the link and are brought to a DocuSign page and are prompted to put in your email.
Now let’s pump the breaks. Could something be wrong here?
Recently, our Data Science Team (DSI) encountered a threat that had embedded itself on a reputable site.
The Case:
This particular phish had breached the web infrastructure of this site, and established a falsified web page.
Our DSI team examined some of the history behind this original site, and was able to see for the most part that it looks benign. However there were some flags that led us to a slew of non-unique .ru domains and the redirect in question.
These domains included hot keywords such as “signup”, “signnow”, “counter”, and “maildrop” among others along with randomized domain names.
This is not the normal DocuSign page. This page essentially looks for unsuspecting emails/login information to get access to proper logins. In addition, it's not typical for a cyrillic redirect to show up in your browser—unless you have that as a default language—and even from there, it’s missing a few components of a typical DocuSign login. A trusted DocuSign login page will have “Powered by DocuSign” in the lower left, an up-to-date Copyright date (this threat was found in 2022, but the date was still 2021), and some of the text in the footer is slightly different.

What Can I Do?
How can you protect yourself? Always verify your links, and always look at who’s sending the email. Sometimes it can be tricky, but when expecting something that has vital information attached, whether it be a bank statement, a document to sign, or something asking for a unique login, it may be worth going to the actual site and entering your information in a fresh browser session. An extra two minutes could save you a world of trouble later.
We are continuing to keep an eye on this particular case, and are also looking for similar cases.
If you have a lead, feel free to reach out! We love making your web experience safer.

The Hire the Stakes, The Greater the Fall
Another late night, exhaustion and sore eyes setting in after sending what felt like the thousandth job application on your list, when yet another reply hits your inbox with the words, “Unfortunately we…”You don’t even need to read the rest; you’re familiar enough with how this goes. Woefully, you sit thinking about the work you’ve put into the job search: The degree, the blood, the sweat, the tears—ping. An email notification graces your frustra...
Risky Apps for Business: Top Malware and Phishing Threats
Not all apps are created equal. Some introduce serious risks for phishing, malware, or data breaches, especially when they’re adopted by employees without IT approval. And while blocking a website at the domain can prevent unauthorized access on your network, many applications have hundreds or thousands of domains—simply blocking the main domain might not be enough to prevent access.
What DNS Needs To Be When It Grows Up: Protective
DNS—short for Domain Name System—has quietly operated behind the scenes as the backbone of how devices find one another on the Internet. But as threats evolve, DNS is no longer just the plumbing: It has to become your first line of defense. That’s the core message from our recent webinar, What DNS Needs to Be When It Grows Up.
