The Nature of the Threat

Proofpoint has reported an increase in social engineering attacks that trick users into copying and pasting malicious PowerShell scripts. These scripts are designed to infect computers with malware. Multiple threat actors are using this method, which, although requiring significant user interaction, can be highly deceptive. The malicious code is often delivered through pop-up messages that seem to indicate an error or issue with a document or webpage.

How the Attack Works

While browsing on Chrome, a user might encounter a pop-up box that suggests an error has occurred. This pop-up will then provide instructions to copy and paste a piece of text into a PowerShell terminal or the Windows Run dialog box. This might seem suspicious at first glance, but the message is crafted to look like a legitimate solution to a common problem, making it easy for users to fall for the trick.

Why This Is Dangerous

Despite the seemingly straightforward nature of the attack, its social engineering aspect is sophisticated enough to deceive even cautious users. Once the malicious script is executed, it checks whether the device is in a virtual or sandboxed environment to avoid detection. If the device passes these checks, the script proceeds to download and install malware, often in the background, making it harder to notice.
