This includes the large, organised criminal groups you read about bringing down large companies in the press on a weekly basis nowadays. A consistent theme I see is companies overestimating the skills of their attackers.

NSA Malware DoublePulsar: How To Test If Your Computer Has Been Infected

The good news is there is significant value in being able to spot commonalities between attacks, and provide top down protection through the stack.

This is something Microsoft Threat Protection is leading the way on, and this is fundamentally why I started looking at this job. I made this tweet in the early hours after Christmas Day because who needs a life? It is high time I put my career where my mouth is, on that front. Security is hard. Microsoft are collecting literally trillions of signals each day across their cloud infrastructure in Azure, services like Office and Hotmail, and across endpoint tools such as Microsoft Defender.

These signals are fed into the Microsoft Security Graph, and essentially you have a database growing petabytes in volume each day around real time attacker activity and global threats:. Back inon this site I made a post around how endpoints and by proxy end users are the new DMZ. The reason at the time was Office macros, which continues to be a huge challenge.

My frustration back then was I could see a clear signal that intrusions were going to move to devices inside the enterprise using pretty simple and cheap techniques — layers of traditional security controls were crumbling. On the endpoint side you have Microsoft Defender — an antivirus tool which a decade ago was the laughing point of the security industry, but now sits well regarded as a tool across millions of organisations and home PCs. In software, but mostly, people to build said software — and look at the outputs, i.

This view, from Azure, to Defender for Windows, to Defender for Linux, allows a real world, global view of emerging attacks. Let me tell you — SIEM monitoring solutions suck.

Organisations spend big on SIEM solutions because they want to know when hackers break into their network. Quite often SIEM integration projects descend into chucking data into a hole, the hole filling, then everybody ignoring the ugly hole as nobody wants to stare into the abyss of Too Much Suck.

That honeypot, which had almost no customisation and was just real Windows endpoints reporting into Sentinel, detected BlueKeep exploitation in the wild. I would like to spend the final 20 years of my career shouting back from the cloud, helping distribute a rain of real time detection and intelligence. Kevin Delivering stretched metaphors. Sign in.

In the last months there have been various groups of attackers as well as script kiddies that have been using the FuzzBunch Framework to compromise systems. In a recent incident while I was analyzing a memory dump It took me some time to identify that the infection vector was EternalBlue.

Once I found the ring 0 shellcode related to DoublePulsar I was able to approach the analysis more easily. To expedite this process for future analysis I have developed a dummy plugin to make easy to find this implant.

The plugin is not based on Yara rules. It just dumps the array of functions pointers SrvTransaction2DispatchTable from the srv. Note that although the plugin dumps the whole table it would really only be necessary to verify that the SrvTransactionNotImplemented symbol points to the correct place. The plugin resolves SrvTransaction2DispatchTable by getting the.

Once it gets the symbol offset it just dumps the array of pointers. It that case volshell and dis will clear up any doubts. Let see an example. Note the operation opcodes 0x23 ping0xc8 exec0x77 kill. In the previous case the symbol file has been downloaded from Microsoft. I usually use Radare to get this. Labels: doublepulsarNSAvolatility.

Author: Luke Jennings luke. Supports both single IP checking and a list of IPs in a file with multi-threading support. The SMB version also supports the remote uninstall of the implant for remediation, which was helped by knowledge of the opcode mechanism reversed by zerosum0x0. This is an early release in the interests of allowing people to find compromises on their network now that these exploits are in the wild and no doubt being used to target organizations.

It re-implements the ping command of the implant, which can be used remotely without authentication, in order to determine if a system is infected or not. Not all OS versions have been tested and some currently fail. Therefore, it is possible that errors against certain windows versions may be indicative that the system is not compromised.

While we do not condone the reliance on signatures for effective attack detection, due to how easily they are bypassed, these rules are highly specific and should provide some detection capability against new threat groups reusing these exploits and implants without modification.

It is believed to have originated with the NSA. Also to be noted, it is a RAM-resident implantthat is the attack lives in memory. DoublePulsar is a very sophisticated, multi-architecture memory-based kernel payload that hooks onto x86 and bit systems and allows an attacker to execute any raw shellcode payload.

It is a full kernel payload giving full control over the system. It does not open new ports but make use of the same port as the one the SMB service runs on. This malware infects computers running Windows and it opens a backdoor through which other malware can be loaded onto infected computers. As per Dan Tentler CEO and founder of Phobos Croup once the DoublePulsar is present, it can do any of the four following things: 1 either it responds to a specific ping request such as a heartbeat2 it can uninstall itself, 3 load shellcode, or 4 run a DLL on the host.

These are the only purpose of this malware. It means there is a loading dock ready and waiting for whatever malware anyone wants to give it. A free tool that can be used to test whether the computer is infected with the DoublePulsar backdoor is available here. Based on the response of port to a particular ping, the test results were obtained. The intent of this request is to check if the system is already compromised.

If a system is infected, then SMB can be used as a covert channel to exfiltrate data or launch remote commands. Below image show response of DoublePulsar infected system:.

Initial reports highlighted attacks impacting healthcare organizations—especially the National Health Service NHS in the United Kingdom—preventing the ability to treat patients across much of their healthcare network.

Since then, the attack has also been reported in Chinese universities, German train station monitors, parking meters, and digital billboards. The initial point of infection and attack vector specifics are still developing, but once a host is infected it is loaded with WannaCry and the DoublePulsar backdoor payload; then, the host starts scanning for other vulnerable hosts for propagation via EternalBlue Microsoft published a patch for EternalBlue in MS in March Once infected, system users will be greeted with the following screens.

WanaCrypt0r has actually been around for months, with limited infections reported. The attack uses WanaCrypt0r 2. This new bundle enables it to propagate through a network and infect additional systems running Microsoft Windows without any intervention from users to open an email, click on a link, or open an attachment.

EternalBlue and DoublePulsar were two of several potent exploits published in the most recent Shadow Brokers release in mid-April. The attack was halted on Saturday, May 14, when a cybersecurity researcher activated a kill-switch by registering the single domain used in the ransomware virus.

What can users and organizations do to protect themselves from WannaCry and possible variants? Regarding patching and upgrades: I know this is not always so simple, especially for large organizations or for application owners that work with layers of third-party add-ons and custom software that sit on top of Windows operating systems. Upgrades, or even patches, require testing for stability, regression testing for features, internal security testing etc.

If you were having problems getting resources approved in your company for testing, patching or upgrades, WannaCry should present a strong argument next time around. There are already numerous claims citing new variants of WannaCry identified in the wild within social media circles.
