Source Code of Iran-Linked Hacking Tools Posted Online

What appears to be the source code of hacking tools used by an Iranian cyber-espionage group has been posted online along with information apparently stolen from victims. 

The data, posted online by a group of alleged Iranian hackers called "Lab Dookhtegan," is supposedly related to the infamous OilRig hackers. Also known as APT34 and active since at least 2014, the OilRig group is believed to be backed by the Iranian government. 

Over the years, OilRig has been targeting organizations in the financial, government, energy, telecoms, and chemical sectors in the Middle East, and has been heavily reliant on DNS tunneling for communication with the command and control (C&C) server. 

Starting in late March, information on the tools used by the hackers in their attacks started to emerge on a Telegram channel called Read My Lips, but the leak did not gain much attention until late last week, when several blogs and news articles on the data started to emerge. 

The leaked data also included IP addresses and domains that the cyber-espionage group has been employing in their campaigns, evidence of intrusion at tens of organizations worldwide, and even the identities and photographs of individuals allegedly working for the group. 

Hacking tools exposed in the leak include Glimpse, an updated version of the BONDUPDATER PowerShell-based Trojan, PoisonFrog (an older version of BONDUPDATER), HyperShell (also known as TwoFace), HighShell/HyperShell (web shell), Fox Panel (a phishing kit), and Webmask (a tool for DNS tunneling). Relevant passwords were apparently removed from the tools.

Some of those who analyzed the leaked data say that the dump also includes information apparently stolen from victims, such as private keys and credentials (including Domain Admin credentials for various domains). 

The data suggests OilRig managed to compromise a broad range of organizations, most of which are located in the Middle East. 

The Lab Dookhtegan hackers claim to be focused on destroying OilRig and their actions appear meant to embarrass the group. They also claimed to have wiped the servers of the Iranian hackers and even posted screenshots supposedly showing the message they left for the cyber-spies to find.

The identity of the leakers, however, remains unclear. It is also unclear whether the individuals mentioned in the leak are indeed connected to the OilRig group or not, as the entire move might be nothing more than a disinformation campaign.

The leak is reminiscent of Shadow Brokers, who posted online a great deal of tools they claimed to had stolen from the U.S. National Security Agency-linked Equation group.
