UPDATED Advisory: Data leakage of multiple 0-days and tools

Stay updated on our security analysts’ findings and recommended actions.

Update 16.04.2017: Added new tools and 0-days against Solaris, Redhat, Avaya Call Server and Samba.

Update 17.04.2017: Confirmed observations of ransomware distribution leveraging the leaked NSA exploits.

Update 20.04.2017: Added CVE details to exploits (where available), new exploits, updated descriptions, updated summary, added references.

Update 21.04.2017: Added update to summary that as of 20.04.2017, approximately 15 000 systems have been observed to be compromised with "DoublePulsar".

Update 25.04.2017: Added update that the number of compromised hosts with “DoublePulsar” installed is now reported to be more than 200 000 machines. Updated summary to reflect that Argus Continuous Vulnerability Monitoring (part of the Argus Managed Defence suite) customers will now receive notifications if any of their internal or external systems have “DoublePulsar” installed.

Update 15.05.2017: Added update to summary regarding the WannaCry ransomworm that spread across the Internet on Friday May 12th by leveraging the EternalBlue exploit.

Update 27.06.2017: Added update to summary regarding the Petya/ NotPetya/ GoldenEye ransomware spreading. For more information about this, please visit our latest advisory here.

Last year a group named “The Shadow Brokers” attempted to auction a data dump allegedly claimed to come from the NSA. The dump consisted of multiple tools and information about vulnerabilities for a wide range of applications and operating systems. At the time, the group was not able to sell the dumps at their desired price. The actor behind the tools and exploits has also been called “Equation Group”.

On April 8th, 2017 The Shadow Brokers published the password for one of the encrypted dumps that was made public last year. This dump included several tools and vulnerabilities for attacking Linux and other Unix based operating systems and applications.

On the 14th of April the group made available three more data dumps. These dumps include vulnerabilities, tools, operative notes from (allegedly) the NSA and a framework for running exploits and building malware. Amongst the dump are several vulnerabilities that can be used to target various Windows operating systems ranging from Windows XP to Windows 2016.

Most of the vulnerabilities in the published dumps were patched by Microsoft in March 2017. Argus Managed Defence – mnemonic’s Managed Detection and Response (MDR) service - detects most of the disclosed attacks and has contained signatures both in log analysis and network detection services for quite some time. The Argus Continuous Vulnerability Monitoring service (part of the Argus Managed Defence suite) also detects systems compromised by “DoublePulsar”.

The data from the dumps seem to be from 2013 and earlier and therefore does not appear to include any ready to use exploits against Windows 10 or Windows 2016.

While the exploits and attack tools are important to build detection capabilities and mitigation strategies for reducing the attack surface, of even more concern may be the additional data and tools in the dump.

The data includes a playbook on how an advanced attacker can comprise networks, maintain persistence and remain undetected. The tools include advanced capabilities for hiding backdoors, control channels and installed utilities, along with deleting single records within log files and changing timestamps. Although some of the techniques are not new, they are now gathered together and include documentation to enable any threat agents to attack with advanced capabilities. 

Update 21.04.2017: Multiple reports are confirming that the leaked tools are being used to exploit and compromise machines and networks. Initial scanning with Shodan showed on Thursday April 20th around 15 000 systems compromised with "DoublePulsar".

Update 25.04.2017: The number of compromised hosts with “DoublePulsar” installed is now reported to be more than 200 000 machines. Note that customers of mnemonic's Argus Continuous Vulnerability Monitoring service (part of the Argus Managed Defence suite) will receive notifications if any of their internal or external systems have “DoublePulsar” installed.

Update 15.05.2017: On Friday May 12th, the WannaCry ransomware was distributed using a worm leveraging the EternalBlue SMB exploit. The worm exploits the SMB vulnerability patched by Microsoft in March 2017 (MS17-010) and spreads itself both on the local network and over the Internet on port 445. After successful exploitation, it installs the DoublePulsar backdoor and then proceeds to load the ransomware component. Numerous technical articles about this attack have been published, and the attack has been covered extensively by the mass media. The WannaCry attack also has a dedicated Wikipedia page. The only confirmed distribution vector is through the EternalBlue SMB exploit.

What is it?

“The Shadow Brokers” have released three data dumps:

  • Windows: A dump with tools and exploits for exploiting Windows operating systems and third-party applications running on Windows.
  • Oddjob: A framework for building and controlling malware running on compromised Windows machines.
  • SWIFT: Operative notes and data dumps from attacks against providers and financial institutions connected to the economic transactions in the Middle East.

How does this affect me/us?

The vulnerabilities and tools grant anyone the capabilities of an advanced attacker. While these capabilities already exist through Metasploit, the difference is now there are multiple vulnerabilities in widely distributed applications and operating systems affiliated with the tools. Several of the published exploits can also be used in Worms and other wide spread attacks.

It is expected that ransomware and other malware types from cybercriminals leveraging these vulnerabilities and tools will arise within days. Most of the vulnerabilities can be mitigated by updating the software with the latest patches. The actual malicious code currently has low to no detection. Some of the malicious code also run in the kernel of the operating system and once installed is difficult to detect both within the network and on the system itself.

Update: On April 16th we observed exploits from the Shadow Brokers dump being repurposed for the distribution of ransomware. 

Technical details

Unfortunately for defenders this was published on the Friday during the Easter holidays, and the data dumps are large. There is currently limited information about the extent of the dump, but our initial investigations point towards this dump causing substantial damage towards multiple organizations. 

We have added CVE details for the exploits where we have matched the vulnerabilities to existing vulnerabilities (or newly assigned CVE). The CVE descriptions can be helpful to identify if your organization has any of the vulnerable applications (and versions) installed and how to mitigate the vulnerabilities. Most of the exploits in the dumps are against old applications and versions. Most of these are no longer supported by the vendors or the vendors have patched the vulnerabilities. Some of them are within the 0-day category.

Some of the details we currently have available:

  • Zippybeer:

SHA256/MD5: Descriptions on how to exploit. Hash not usable.

CVE: Unknown/Currently not assigned

Description: Python framework for exploiting a authenticated Windows Domain Controller.

 

Although none of the exploits work against Windows 10 and Windows 2016, Microsoft update MS17-010 also includes patches for these platforms with impact of remote code execution. This means that you should make sure that all systems are running with the latest patches.

The dumps also include old exploits against SSH, Netscape Enterprise, dtscpdx (Solaris), Linux Xorg, Exim MTA, iPlanet and more. 

Tools/Utilities

The dump from “the Shadow Brokers” contains multiple tools and utilities for exploiting, controlling, exfiltration of data and conducting post-exploitation tasks. This part of the release perhaps represent the elements that will have the most severe impact in the long-run.

It contains detailed documentation on how an advanced attacker avoids detection, removes deployed tools and protect their control over the compromised environment. The tools show advanced encryptions tools used, how to create hidden channels in/out of compromised networks and how to work with environments in various operating systems. 

List of codenames for tools and malware installed at compromised machines.

  • DanderSpritz

GUI-based framework for conducting post-exploitation tasks. The frontend interacts with an exploited machine and can perform multiple tasks related to post-exploitation and controlling of the host. Supports retrieving data, cleaning logs, changing timestamps and more. 

  • Doublepulsar

Kernel based backdoor, which can be reached by “portknocking” RDP/SMB. Since the backdoor is installed in kernel level it is difficult to detect. Some tools have been released which can scan machines from the network to detect installed DoublePulsar. 

  • FuzzBunch

Python based framework for running exploits and tools against target machines and applications. The framework is built for running on Windows machines. The version within the data dump from “the Shadow Brokers” contains 13 exploits and various additional tools for running on compromised machines. The framework is similar to the open source project Metasploit. 

  • GROK

Framework for keylogging first described in the Snowden release. Now released as part of the Windows-dump by Shadow Brokers.

  • Oddjob

Tool for building and controlling backdoors/Trojans/malware on Windows platform. The command and control for controlling compromised machines uses HTTP for communication.

  • Ripper

Tool for extracting data from Google Chrome, Skype and Firefox.

  • Scanner

A handy network scanner tool for reconnaissance.
