ACA Aponix Guidance
ACA Aponix recommends taking the following steps to prevent malware infections via OLE objects:
- Alert and train staff on phishing and spear-phishing attacks and the dangers of email attachments;
- Consider using EMET and/or application whitelisting; and
- Disable OLE functionality in Microsoft Office by changing the value of the registry key HKCU/Software/Microsoft/Office/< Office Version >/< Office application>/SecurityPackagerPrompt to 2. More details can be found in here. This change should be tested as it could affect add-ins such as Bloomberg.
