Since this was discovered, Microsoft has added the following mitigation to disable previewing of RTF and Word documents:
1. In the Registry Editor (regedit.exe), navigate to the appropriate registry key:
For Word documents, navigate to these keys:
* HKEY_CLASSES_ROOT.docx\ShellEx{8895b1c6-b41f-4c1c-a562-0d564250836f}
* HKEY_CLASSES_ROOT.doc\ShellEx{8895b1c6-b41f-4c1c-a562-0d564250836f}
* HKEY_CLASSES_ROOT.docm\ShellEx{8895b1c6-b41f-4c1c-a562-0d564250836f}
For rich text files (RTF), navigate to this key:
* HKEY_CLASSES_ROOT.rtf\ShellEx{8895b1c6-b41f-4c1c-a562-0d564250836f}
2. Export a copy of the Registry key as a backup.
3. Now double-click Name and in the Edit String dialog box, delete the Value Data.
4. Click OK, See Also: Hacking Stories: Andrian Lamo – The ‘homeless’ HackerWord document and RTF file previews are now disabled in Windows Explorer.
To enable Windows Explorer preview for these documents, double-click on the backup .reg file you created in step 2 above.
While these mitigations will help, as the exploit has been modified not to use ActiveX controls, users are still at risk until an official security update is released.
Until Microsoft releases a security update, everyone should treat all Word and RTF attachments suspiciously and their source manually verified before opening them.

hacking: security in practice
I was forced to download AnyDesk at work.
Hi guys, I was forced to download AnyDesk for my new workplace since they wanted to help me set up. I’ve watched the whole process from start to finish and so far they’ve only downloaded the new version of MS office (mine was really old), LastPass, Outlook, Clickup and setting up my work email basically. They would require me to leave AnyDesk on and they mentioned that they would be tracking my work email, etc. They also mentioned that they won’t be able to track my browsing activities (for personal use) when I disconnect them from my AnyDesk. I just wanted to know if anyone has a similar experience with AnyDesk and is it safe?
PS. Is this procedure/behaviour normal in companies or should I be seriously concerned?

Do I need a monitor mode/packet injection network adapter to use it or does it just not work?
