Recently, “Prevx” published a report stating that Microsoft released a Security Patch in November that should LockDown and tighten the security of the Registry, but that had a side effect of falsely locking down valid registry key permissions, to leave the user with a Black Screen after he/she logs into the system.
 
Update (2009/12/01): Microsoft Security Response Center has analyzed the issue and confirms that the Black Screen bug is not due to any of the November Security/Non-Security Updates. But, in fact it is related to a Malware/Trojan known as “Win32/Daonol“!

 

 
So, you probably own an iPhone, and you jailbroke it to support your carrier. You should lock-down your iPhone to keep the recent iPhone-Targeted Worms out of your device and to keep your information safe.
 
One of these solutions will keep you safe:

• Change your “root” and “mobile” user passwords
• Uninstall “OpenSSH” from Cydia/Icy

 
An immediate update of “Citrix OnLine Plug-In” is required in order to be safe from the recent Man-In-The-Middle Attack exploiting the newly discovered SSL/TLS Renegotiation Vulnerability.
 
If you are connecting to a Citrix Gateway, we recommend you update your plug-in as soon as possible from here:
