It blocks access to websites that contain certain strings, which are mostly related to antivirus programs. It modifies registry entries to disable various system services. This action prevents most of the system functions to be used. It drops copies of itself into all the removable drives connected to an affected system. It drops copies of itself into network drives.

INF file to automatically execute the copies it drops when a user accesses the drives of an affected system. It exploits software vulnerabilities to propagate to other computers across a network.

It modifies certain registry entries to hide Hidden files. It prevents users from visiting antivirus-related websites that contain specific strings. The said. INF file contains the following strings:. It exploits the following software vulnerabilities to propagate to other computers across a network: Vulnerability in Microsoft's Server service.

It connects to the following time servers to determine the current date: myspace. SYS in a certain memory location. SYS in memory. It then sends the control code patch code to the linked device object. If it does, this worm assumes it is running as a scheduled task. Exports functions used by other malware. DLL , which is also located in the Windows system folder. It does this to prevent early detection as a newly added file on the affected system.

Checks the operating system version of the affected system. Propagates by taking advantage of a vulnerability discovered in certain Microsoft operating systems that could allow remote code execution if an affected system received a specially crafted RPC request, which also contains a shellcode. More information on the said vulnerability can be found in this Microsoft Web page: Microsoft Security Bulletin MS Once this specially crafted RPC request reaches its target vulnerable system, the shellcode is decrypted, and then retrieves certain APIs capable of downloading a copy of the worm from the affected system, which is already converted into an HTTP server.

It first broadcasts the opened random port that serves as an HTTP server so that it is accessible over the Internet. Any more feedback? The more you tell us the more we can help. Can you help us improve? Resolved my issue. Clear instructions.

Easy to follow. No jargon. Pictures helped. Didn't match my screen. Incorrect instructions. This fix addresses an issue that intermittently misdirects AD Authority requests to the wrong Identity Provider because of incorrect caching behavior.

This can effect authentication features like Multi Factor Authentication. Fixed a problem where during upgrade of R2 AD FS farm to AD FS , the powershell cmdlet to raise the farm behavior level fails with a timeout when there are many relying party trusts. This will allow "Kiosk Scenarios" where multiple users might be serially logged into a single device where there is federation with an LDP.

Scopes and IdentityServerPolicy. Clients tables due to a foreign key constraint. Such sync failures can cause different claim, claim provider and application experiences between primary to secondary AD FS servers. This update fixes an issues where Multi Factor Authentication does not work correctly with Mobile devices that use custom culture definitions. Addressed an issue where the PkeyAuth token handler could fail an authentication if the pkeyauth request contains incorrect data. The authentication should still continue without performing device authentication.

A "Disabled" option was added to restore scenarios where non-password authentication is used. The vulnerability could allow information disclosure if an attacker sends a specially crafted request to an AD FS server, allowing the attacker to read sensitive information about the target system. Hotfix for update password feature so that users are not required to use registered device in Windows Server R2.

You are not prompted for username again when you use an incorrect username to log on to Windows Server R2. Authentication through proxy fails in Windows Server this is the general release of hotfix Authentication through proxy fails in Windows Server R2 SP1 this is the general release of hotfix AD FS 2. MS Vulnerability in Active Directory federation services could allow elevation of privilege.

Memory usage of AD FS federation server keeps increasing when many users log on a web application in Windows Server Update is available to fix several issues after you install security update on an AD FS server. A comma in the subject name of an encryption certificate causes an exception in Windows Server R2 SP1.
