The server that is serving view.php appears to be filtering on the user-agent string, as visiting the site with a browser displays a standard image for the webpage. Note this domain appears to be a legitimate domain, which has been compromised and is being used by these operators.
Figure 6. HTTP GET request to view.php on quickwaysignstx[.]comIf the user-agent string in the request is Windows Installer, an MSI file is returned. This user-agent string is part of the msiexec command, further supporting that the payload will only be downloaded when using msiexec. The MSI payload (SHA256: 41D27D53C5D41003BC9913476A3AFD3961B561B120EE8BFDE327A5F0D22A040A) was built using an unregistered version from www.exemsi[.]com with the title of MPZMZQYVXO patch version 5.1.
The PowerShell script appears to have been generated using the open-source script Out-EncryptedScript.ps1 from the PowerSploit framework. It contains a blob of data that is obfuscated via base64 and is TripleDES encrypted with a cipher mode of Cipher Block Chain (CBC).
Once the main NetSupport Manager executable (presentationhost.exe) is started, it beacons to the domain geo.netsupportsoftware[.]com to retrieve geolocation of the host followed by an HTTP POST to [.]182/fakeurl.htm
Throughout the first half of November, all related activities used email attachments containing the name of an individual publicly associated with the target company or utilizing the name of a public figure. Most public figures referenced belonged in the film or print industry. All emails were also sent using a random protonmail[.]com email address and contained email subjects related to refund status or unauthorized credit card transactions. Beginning at the end of November and continuing into January 2020, the mail attachments changed and were instead named as .doc and sent from email addresses using domains that were registered within one day of the observed activity. The email subjects contained the same trend reusing themes associated with refunds, as well as transaction and order inquiries. While it is unclear what the overall motivations of this activity is, these changes may increase the likelihood of a recipient opening the email attachment and indicate a desire to gain access to the target network.
Palo Alto Networks customers are protected from this threat via multiple services. Our threat prevention platform detects both the NetSupport Manager file along with the related payloads, including URL retrieval. Cortex XDR customers are further protected by behavioral indicator signatures. AutoFocus users can track related activities using the NetSupport Manager tag.
Palo Alto Networks has shared our findings, including file samples and indicators of compromise, in this report with our fellow Cyber Threat Alliance members. CTA members use this intelligence to rapidly deploy protections to their customers and to systematically disrupt malicious cyber actors. For more information on the Cyber Threat Alliance, visit www.cyberthreatalliance.org. (This is added to blogs pre-shared with the CTA, when loaded into WordPress it will be added when appropriate).
I can replicate it on a brand new project with a single component placed on a window and left at default. It can be caused by conditions within the client PC. The number of faults triggered corresponds with the number of components on the window.
I can confirm what Tim is writing. After a lot of investigation and support from Inductive we found that it was when we connected remote to the clients using SSCM we got this error. So, there must be something in the java provided with I8 that really dislikes remote connections that shadows the client. Remote desktop works fine for us.
Adversaries occasionally leverage scheduled tasks to reach out to external domains and download arbitrary binaries on a set or recurring schedule. Like most of the adversary actions described in this section, this is a way of establishing persistence. Keep an eye out for scheduled tasks running with the /create command and a reference to a URL in the command line.
I have a VB project (part of a Visual Studio 2013 solution) which targets .NET 4. The remote server to which the app sends a web request has stopped supporting TLS 1.0 (which is the default in .NET 4) so the app stopped working, with exactly the same error message expressed at the top of this article. Rather than change the .NET target, I added the line of code as follows:-System.Net.ServicePointManager.SecurityProtocol = DirectCast(3072, System.Net.SecurityProtocolType)This appears to have done the trick.Huge thanks!
As per the Microsoft site -us/dotnet/api/system.net.servicepointmanager.securityprotocol?view=netframework-4.7#System_Net_ServicePointManager_SecurityProtocol:Starting with the .NET Framework 4.7, the default value of this property is SecurityProtocolType.SystemDefault. This allows .NET Framework networking APIs based on SslStream (such as FTP, HTTP, and SMTP) to inherit the default security protocols from the operating system or from any custom configurations performed by a system administrator. For information about which SSL/TLS protocols are enabled by default on each version of the Windows operating system, see Protocols in TLS/SSL (Schannel SSP).For versions of the .NET Framework through the .NET Framework 4.6.2, no default value is listed for this property. This suggests that for .Net 4.6.2 and earlier, you would need to set the TLs version in code using ServicePointManager, etc.
During this review, the Falcon Complete analysts expanded their investigation to analyze similar activity in another customer environment. In this case the NetSupport remote admin tool had attempted to spawn under a different tool that a user had also downloaded from GitHub. The process tree was virtually the same as the one shown in Figure 1, except with a different administrative tool.
The Falcon Complete team had successfully remediated the victim environment and identified the problem but remained curious about how these GitHub wikis had been tampered with. How could GitHub accounts that had been created only recently edit wikis for highly popular GitHub accounts? To find out, Falcon Complete analysts went to the source, logging in to GitHub to see what the threat actors were seeing, and noticed the buttons shown in Figure 8.
MaaS makes it easy for threat actors to leverage well-developed and fully functioning remote access tools without needing to know how to program. This highlights the malicious benefits of MaaS tooling and services, enabling less technically capable actors to conduct multiple campaigns.
In this intrusion, a threat actor abused the CVE-2022-30190 (Follina) vulnerability, where exploit code was embedded inside a malicious Word document to gain initial access. We assess with medium to high confidence that the documents likely arrived by the means of thread-hijacked emails from distribution channels used by TA570.
After this activity, the threat actor proceeded with the remote creation of Qbot DLLs over SMB on multiple hosts throughout the environment. They then added multiple folders to the Windows Defender exclusions list on each of the infected machines to evade defenses, as we have seen before with Qbot. Remote services were then used to execute the DLLs.
Ever since the disclosure of the Follina vulnerability (CVE-2022-30190) earlier this year, threat actors have been known to leverage the flaw in various phishing campaigns. Delivery of this intrusion was linked to TA570, using hijacked email threads to deliver the initial payload. This intrusion started after a Word document, weaponized with Follina exploit code, was used to deliver and infect the host with Qbot malware.
When dealing with a Word document based on the OOXML format, associated files and folders are stored within a compressed ZIP archive. These items can be easily extracted by using an arbitrary zip utility like unzip . One of the embedded files that requires inspection during the analysis of a Follina maldoc, is named document.xml.rels
On one of the targeted systems, the injected explorer process opened a handle with suspicious access rights to a thread in the LSASS process. Credential dumping tools like Mimikatz often request this level of access and corresponds to the following access rights:
