Threat LevelModerate threat
DistributionNot widespread


Proxy.O allows hackers to get into and carry out dangerous actions in affected computers, such as capturing screenshots, stealing personal data, etc.


It uses the following techniques to impede detection by antivirus companies:
  • It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.


It captures certain information entered or saved by the user, with the corresponding threat to privacy:

  • Keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information.
It then sends the gathered information to a remote user by any available means: email, FTP, etc.


It causes a loss of productivity in the local network to which the compromised computer belongs:

  • It generates a large amount of network activity and consumes bandwidth.


It reduces the security level of the computer:

  • It opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality.
  • It notifies the attacker that the computer has been compromised and is ready to be used maliciously.


Means of transmission 

Proxy.O does not spread automatically using its own means. It needs the attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.

Further Details  

Proxy.O has the following additional characteristics:
