Let’s face it, hackers do whatever they can to get you to click on their link. And they have a lot of tools in their toolbox to get you to click. Everything from social engineering to display name spoofing to domain name spoofing. It’s all to get you to do one thing: click the link.

Now, they’ve come up with something that may be harder to defend yourself against: invisible text. To be sure, hackers have been using techniques similar to this for a while. According to an article on Dark Reading, “Attackers are continuously testing enterprise security systems and exploring new ways to get through. Some rely on hidden text and zero-font attacks, in which they put invisible characters between the letters of an email so it doesn’t trigger email defenses with phrases like “password expired” or “Office 365.” These malicious emails appear legitimate to any unsuspecting user.”

In response to this hidden text tactic, Secure Email Gateways (SEG) started looking for it so it could reject emails with these obviously hidden letters. And that worked for a while. But it wasn’t long before hackers had their own counter move: the soft hyphen.

Continuing from the article, “To get around that, the attackers have used the Unicode Soft Hyphen. To the user, it is all invisible. In a text editor, the soft hyphen appears as you’d expect, a hyphen. However, the text editor also shows that every letter is separated by a soft hyphen. What is important here is that the SEG also sees the soft hyphen. As such, the phrases are not flagged at all. It is this that is defeating the SEG and failing to mark the email as malicious.”

From Security Boulevard, “This type of phishing scam is nasty because the average person has no idea the capability to sneak in this type of code existed.”In other words, all the security awareness training in the world will not protect you from an exploit this sophisticated.
