Run the automated removal tool to eliminate Conficker/Downadup.

Using an IP address instead of the hostname will bypass the worm's blocking routines, so that tool could be downloaded by infected systems at this URL:

Or, F-Secure also has a removal tool available, however the domain is in the blocked list of domain names above.

Since this is a third party hosting company, their domain name is not on the blocked list, so one can substitute 'mscom-dlcecn.vo.' for '' in the MSRT URL. One can use a direct link to the MSRT on Microsoft's content delivery network server.

Or, if no proxy is available, a workaround is needed.

Use a proxy server to download Microsoft's Malicious Software Removal Tool (MSRT) from the following URL:.However, the worm does not prevent use of a proxy server to reach the same websites, so in organizations where a proxy server is already in use for web traffic, removal may be easier. Obviously not being able to reach any of these domains makes it difficult for an infected party to find information on or cleanup tools for the worm. The complete list of strings blocked in DNS requests is below: cert. It does this by hooking the system DNS and networking APIs and blocking DNS lookups where certain strings are present in the domain name. The problem of Conficker/Downadup cleanup is exacerbated by the fact that the worm blocks the download of potential removal tools, including Microsoft's own Malicious Software Removal Tool (MSRT) which has been updated to remove Conficker/Downadup. Workstations no longer able to access or other security/AV related websites.Network logins being locked out for too many failed attempts.

Network drives/USB drives with hidden autorun.inf files, especially ones that are larger than 512 bytes.Whatever the real number of infected machines, it is certainly possible that it has infected millions of machines around the world based on the sheer number of IP addresses hitting sinkhole servers that have been set up for observation. Estimates are currently around 10M infected machines, although it is possible that machines are being counted multiple times by some entities.

To date SecureWorks has not witnessed any successful downloads of second-stage code, however, it is believed the intention of the worm may be to install rogue anti-virus software in an attempt to scare payment out of infected users.ĭespite using fairly old and well-known spreading vectors, and a patch being available for MS08-067 for months now, the worm is having fairly good success at spreading to networks worldwide. Each day a new set of 250 domain names will be generated.

Waits three hours, then attempts to download additional code by generating 250 different domain names and connecting to each via HTTP.

Adjusts the Windows TCP/IP settings to allow a greater number of simultaneous connections in order to facilitate the spread of the wrom.

Adds itself to any removable/network drives using an autorun.inf file.

#PHOTOMINER WORM SPREADS VIA INSECURE FTP SERVERS PASSWORD#

Spreads through the local Microsoft network using password brute-forcing or MS08-067 exploit.

Disables access to multiple websites related to antivirus and security, most notably Microsoft and Windows Update.

Disables certain Windows services that might aid in cleanup or detection of the worm.

Adds itself as a randomly-named system service for persistence after reboot.

Copies itself to the system directory as a randomly-named DLL file.

Once installed, the worm does the following things:

The reason is they are infected by the Downadup worm.ĭownadup (also called Downad, Kido, Conficker or Conflicker) is a Windows worm that spreads by exploiting weak administrator passwords, use of autorun on removable and network drives, and the MS08-067 exploit. Millions of other people are also finding that they can't reach or can't load antivirus websites. If you've been seeing this message in your web browser lately, you are not alone:
