Criminals are using social engineering techniques to target organizations worldwide with malicious PowerShell scripts disguised as fake error messages from Google Chrome, Microsoft Word, and OneDrive. Proofpoint identified at least two criminal groups using this tactic, with the possibility of spreading ransomware. Organizations are advised to train employees to recognize and report such attacks.
Based on the meeting notes, it seems that there is an ongoing threat of social-engineering attacks using fake error messages to trick users into running malicious PowerShell scripts. The attackers are using various techniques such as fake error messages related to Google Chrome, Microsoft Word, and OneDrive to prompt users to click on fix buttons and run PowerShell scripts. These scripts then download and execute various types of malware on victims’ machines, including ransomware.
The attackers are using a variety of tactics, including compromised websites, fake browser updates, and phishing emails, to distribute these malicious scripts and infect users’ machines. Proofpoint has identified at least three criminal gangs using these techniques and has provided indicators of compromise to help organizations identify and respond to these threats.
It is important for organizations to train employees to recognize and report suspicious activity related to these types of social engineering attacks. It may also be beneficial to implement security measures to prevent users from running potentially harmful PowerShell scripts and to keep systems up to date to minimize the risk of exploitation.
Let me know if you need any further assistance or specific action items to address these security concerns.
