Zero-Day Spear Phishing Attack Targeting Covid-19 Pharmaceuticals—Likely Nation-State Threat Actors

Today, SlashNext Threat Labs observed a flurry of spear-phishing attacks targeting companies at the forefront of Covid-19 vaccines and therapeutics development. These attacks are active, and as of this writing, there are more than 800 spear phishing domains over 60 days that belong to the same threat actors. There is nothing more critical in the age of Covid-19 than finding a cure, and hostile nation-states who cannot develop their own cure would rather steal it.

In all cases, these attacks point to Office 365 log-in pages. These spear-phishing attacks are designed to appear trustworthy. They are targeting specific individuals, in this case, companies that are working on Covid-19 vaccines or therapeutics in an attempt to steal sensitive account credentials. This threat actor chose to launch a flurry of spear-phishing attacks because it’s the most successful form of acquiring confidential information. The impersonated page is virtually identical to the legitimate page and is hosted on a spear-phishing domain.
