Spear Phishing – SEC Campaign

1 minute read
Speak With A Security Expert Now

The Threat

The eSentire Security Operations Center has observed a spear phishing campaign targeting customers in the financial industry. The email claims to originate from the Securities and Exchange Commission and arrives bundled with a malicious Microsoft Word Document. The document uses the Dynamic Data Exchange (DDE) protocol to execute malicious PowerShell code which downloads and executes DNSMessenger malware. If successful, this attack allows the threat actor to interact with the victim’s system.
