Sobre 5,000 HPE iLO 4 Interfaces batida por ransomware

Este artigo é sobre uma ameaça ransomware recente que tem milhares de sucesso da Hewlett-Packard Empresa Integrated Lights-Out 4 as interfaces ou HPE iLO 4 abreviado. Estas interfaces fornecem acesso aos servidores HP Enterprise e seu controle remoto. The ransomware threat is encrypting the hard drives of the servers and then demanding Bitcoins as a ransom to restore the files within the drives. A security researcher that goes by the twitter handle @M_Shahpasandi has been the first to make the discovery of the attack.

What Is Hewlett-Packard Enterprise iLO and Related Interface?

iLO is a remote server management processor embedded on the system boards of Hewlett-Packard Enterprise ProLiant servers and Synergy compute modules. The management processor enables the monitoring and controlling of servers from remote locations. HPE iLO management is a powerful tool that provides multiple ways to configure, atualizar, monitor, and repair servers remotely.

The iLO web interface groups similar tasks for easy navigation and workflow. The interface is organized in a navigational tree view. The top-level branches are Information, iLO Federation, Remote Console, Virtual Media, Power Management, Rede, Remote Support, and Administration. Em poucas palavras, these interfaces provide administrative access to all servers which are under the command of the interface.

It seems that for now HPE iLO interfaces that have been hit by the ransomware threat are publicly accessible. Sobre 5,000 iLO-4 have been found to be exposed publicly as Shodan statistics mostrar.

If HPE iLO interface is hit by the ransomware, the security banner will be changed. The altered Login security banner added by attackers states the following:

Security Notice

Here is an image depicting the security banner shared by @M_Shahpasandi on Twitter:

Victims report that the attack indeed encrypts or wipes the hard drives that were targeted. The chronological order of the attack is the following:

  • Access is gained to the Integrated Lights-Out interface
  • The Security Login Banner has been enabled
  • A remote ISO has been mounted
  • Scripts or programs are run from the ISO
  • The server is rebooted

It is speculated that the attackers used to gain access by either executing the CVE-2013-4786 vulnerabilidade, which allows an offline brute force attack for a password hash of a valid iLO user or via the CVE-2017-12542 vulnerabilidade, which allows an authentication bypass, solved by updating to iLO version 2.53.

Many security researchers advise that HPE iLO 4 or any other similar remote control interface for servers should never be connected to the public Internet. Secure VPNs should be used for access and you should have the latest firmware installed which is available at all times.
