Figure 1. Screenshot of archives. Four days after this activity began, on Oct. In the days that followed, we observed similar activity across six other organizations, with exploitation against one U. In continuing to track this actor's activities, we believe it is also important to note that on Nov. This domain is associated with another ManageEngine product that provides Managed Service Providers MSPs with the ability to manage passwords across multiple customers in a single instance.

Earlier this year, Zoho released a patch for CVE affecting this product. Two days later, Zoho released a security advisory alerting customers of active exploitation against an unauthenticated remote code execution RCE vulnerability affecting ServiceDesk Plus versions up to With a severity rating of critical, this vulnerability can allow an adversary to execute arbitrary code and carry out subsequent attacks.

However, it is also worth noting that Zoho released an update on Sept. We are not currently aware of any publicly available proof of concept code for how to exploit this vulnerability. Additionally, given that the vulnerability was only disclosed after attacks began, we assess that the actor independently developed exploit code for their attacks. The first is to upload an executable specifically named msiexec.

Both of these requests are required for successful exploitation, and both are initiated remotely via the REST API without requiring authentication to the ServiceDesk server. With our understanding of this vulnerability, we created the threat prevention signature Zoho ManageEngine ServiceDesk Plus File Upload Vulnerability to block inbound exploitation attempts.

After successfully exploiting an internet-facing instance of ServiceDesk Plus, on Nov. Static analysis of this file shows that it was compiled a few days earlier on Oct. Additionally, as seen in malware in previous campaigns, the author of this payload did not remove debug symbols when compiling this sample, which provided two interesting analytical leads. The debug symbol path was as follows:. Secondly, the filename of sd As mentioned above, the actor would execute this payload during the exploitation of CVE by issuing a second request to the REST API, which instructs the ServiceDesk application to run the following command:.

Therefore, the actor uploads the malicious msiexec. We confirmed that the malicious msiexec. Upon successful execution, this sample starts by creating the following generic mutex, which can be found in many code examples freely available on the internet. The tomcat-postgres. In order to load the webshell into memory, the dropper searches for and kills the java.

After killing the Java process, the process is automatically restarted by ServiceDesk Plus, which effectively loads the webshell filter into Tomcat. T he dropper finishes by moving itself to RunAsManager. While the threat actor used the same webshell secret key — ebd1f8f3f — that was previously seen in the attacks on ADSelfService Plus, the Godzilla webshell used in this attack was not a single Java Server Pages JSP file as seen before.

In this particular case, this allows the actor to filter inbound requests to determine which requests are meant for the webshell. The fact that this Godzilla webshell is installed as a filter means that there is no specific URL that the actor will send their requests to when interacting with the webshell, and the Godzilla webshell filter can also bypass a security filter that is present in ServiceDesk Plus to stop access to webshell files.

It appears that the threat actor leveraged publicly available code called tomcat-backdoor to build the filter and then added a modified Godzilla webshell to it. The publicly available tomcat-backdoor source code provided the actors a codebase which they then modified by removing the default code that would run commands from inbound requests with custom code that used the Godzilla webshell.

In order to make the Godzilla webshell work under the filter environment, the threat actor made a few changes to the webshell code as well as, we believe, the webshell controller. For example, the Tomcat filter does not support the HttpSession object. Also, to identify requests to interact with Godzilla, the tomcat-postgres. Recent scans by the Palo Alto Networks Cortex Xpanse platform identified over 4, internet-exposed systems running the ServiceDesk Plus software globally.

The largest population of vulnerable systems was found in the U. Table 1. Global dispersion of vulnerable ServiceDesk Plus systems. As of publication, within the U. In characterizing this vulnerable population, we found systems falling across all industry segments, including 23 universities, 14 state or local governments, and 10 healthcare organizations.

Over the course of three months, a persistent and determined APT actor has launched multiple campaigns which have resulted in compromises to at least 13 organizations. Several of the impacted organizations fall across U. In late October, the actor launched its most recent campaign, which shifted focus toward a previously undisclosed vulnerability in Zoho ManageEngine ServiceDesk Plus software CVE Upon exploiting this vulnerability, the actor uploaded a new dropper that deployed a Godzilla webshell on victim networks with capability to bypass a security filter on ADSelfService and ServiceDesk Plus products.

Given the actor's success to date and continued reconnaissance activities against a variety of industries including infrastructure associated with five US states , we anticipate the number of victims will continue to climb. The best defense against this evolving campaign is a security posture that favors prevention. We recommend that organizations implement the following:.

For Palo Alto Networks customers, our products and services provide the following coverage associated with this campaign:. Threat Prevention provides protection against the Godzilla webshells.
