Tricks from the Past deployed via signed ChatGPT and Claude binaries
Key Points
- Check Point Research discovered a campaign we track as Yoba where attackers abuse the popularity of AI tools such as ChatGPT and Claude, creating fake GitHub projects that pretend to be desktop applications like GPT-5.6 Sol, GPT-6 Astra, and Claude Opus.
- The malware is placed next to legitimate, signed executables from OpenAI and Anthropic so it can be loaded indirectly, a technique commonly known as DLL sideloading, which is often used to bypass security protections.
- This campaign demonstrates strong operational security (OPSEC) by avoiding dedicated command-and-control (C2) infrastructure and instead relying on Telegram, Tor, Catbox, and DNS over HTTPS (DoH).
- The actor behind the campaign shows indicators that suggest Russian origins and appears to operate primarily in the UTC-4 time zone.
Introduction
Over the past two months, we have been tracking a campaign that abuses the popularity of AI tools such as ChatGPT and Claude to spread a custom malware chain we call Yoba. The attackers use fake GitHub projects that pretend to be AI desktop applications like GPT-5.6 Sol, GPT-6 Astra, and Claude Opus. These projects look convincing and use real GitHub infrastructure, which helps them appear legitimate to potential victims. The website exhibits search-targeted content and suspicious installer-delivery tactics consistent with an SEO-poisoning lure.
Inside the installers, there is a malicious component we refer to as the YobaDropper. This dropper includes another component, the YobaLoader, which is responsible for contacting attacker-controlled infrastructure and fetching the final payload. In this report, we describe how victims are lured to these fake projects, how the YobaDropper and YobaLoader work together, and how the attackers ultimately use this chain to run unwanted software on infected systems.
GitHub Repositories
The initial access occurred via malicious GitHub repositories. The projects were impersonating ChatGPT and Claude related models, more specifically GPT-5.6 Sol, GPT-6 Astra, and Claude Opus. No manipulation of fake engagement (stars/forks) was in place.
Aside from the repositories, GitHub.io pages were used to describe the capabilities of the software, while the malware was hosted as a release.
These phishing landing pages contain download links that point directly to the malicious ZIP releases hosted on GitHub.
While the repositories do not show signs of fake engagement (such as artificially inflated stars or forks) that would promote them within GitHub’s own search, they still appear among the top results on Google. This is most likely due to SEO poisoning, where the attackers optimize titles, descriptions, and hosting domains to make their malicious projects rank highly in external search engines.
Each repository uses a different email address (edwardcarlsonmkym[@]outlook[.]com, daxschneiderdjuu[@]outlook[.]com, and rioprestonlfyx[@]outlook[.]com), and the uploader appears to operate in UTC+4, UTC-4, and UTC+3 respectively. This inconsistency likely reflects a deliberate attempt to obscure the threat actor’s true operational timezone.

Although the first repository was created around July 2026, the first two malicious releases were not uploaded until the end of August, and a third malicious release followed approximately five days later.

Malicious zip files hosted on GitHub and other legitimate platforms are usually password-protected, since this prevents automated tools from unpacking and therefore analyzing them. However, neither of these repositories used password protection, as the binaries already had very low detection rates thanks to their anti-sandbox and other anti-analysis techniques.
While the two ChatGPT-related releases and their repositories were created about five days apart, the ZIP files contain mostly the same files, including the malicious components, and they maintain the same IoCs.

By adding the compilation timestamps to this these time-related operations, we are able to determine which files appear to contain the malicious functionality without performing any initial analysis.
| Filename | Compilation Timestamp (UTC) |
|---|---|
| D3dx9_41.dll | 2076-06-18 21:48:40 |
| Setup.exe | 2026-08-19 20:00:27 |

| vulkan-1.dll | 2026-08-19 20:00:27 |
| winmm.dll | 2026-08-30 19:14:19 |
The file that immediately stands out is winmm.dll, which was compiled the same day it was added to the ZIP archive. This suggests it is the component with the malicious functionality, while the other files serve to make the package appear legitimate. The compilation timestamp also indicates the actor is operating in the UTC-4 timezone.
Furthermore, Setup.exe, a legitimate signed OpenAI executable, is used during execution to sideload the malicious DLL. The Setup-Claude.zip file contains the same structure, though in this case Setup.exe is a legitimate signed Claude executable.
YobaDropper – winmm.dll
The malicious DLL contains multiple export names, suggesting that the legitimate winmm.dll has been spoofed. As in many other cases, these exports exist but their code has been stripped out, leaving them mostly empty and reducing the size of the binary.
All 180 exports contain just a return instruction (C3) followed by NOPs (90), and DllEntryPoint is the only one containing actual code.
Anti-Analysis, Pre-Checks
The first function implements an anti-sandbox technique: the malware hashes the basename of its host executable and checks whether the checksum matches the hardcoded value 0xE6C2F326. The hashing algorithm has been identified as DJB2, which other malware families have also used in the past. The malware expects to run under the name Setup.exe, so this check fails if the DLL is executed on its own inside a sandbox environment.
Although a failed check does not terminate the process, the DLL performs 200,000 iterations of Sleep(5500), amounting to approximately 12.73 days, while repeatedly appending the decoded filler string pddy to a local UTF-16 buffer.
In the second function, the malware checks whether the infected user is located in a CIS country by inspecting the system’s keyboard layout. Ukraine was historically included in such checks, but it is not in the list used by recent malware.
The language check is unusual. Instead of comparing the victim’s keyboard language ID against hardcoded values, the malware checks whether the ID falls within the range 0x19–0x44. For IDs in that range, it tests the corresponding bit in the bitmask 0xEC0400C8401 to determine whether the language belongs to a CIS-region country, with an explicit exception for ID 0x22 (Ukrainian). Bazarloader has used a similar technique in the past, with the bitmask 0xD8080190C03.
Language IDs excluded from the infection:
| Russian | Belarusian | Tajik |
|---|---|---|
| Armenian | Azerbaijani | Georgian |
| Kazakh | Kyrgyz | Turkmen |
| Uzbek | Tatar |
The malware continues to resolve Windows API functions dynamically from kernel32.dll and ntdll.dll by comparing hashes of the exported function names. The hashing algorithm is again DJB2, with the initial value 0x1505.
The last check before the malware unpacks and deploys the embedded payload tests whether the process is running with administrator privileges. If it is not, the malware displays the message “Please run this program as Administrator.” to the victim and terminates itself, requiring the user to rerun it with elevated privileges.
Deploying Phase
The dropper contains multiple XOR-encrypted strings that are decrypted when needed. These strings include the file paths where the embedded binaries are dropped, as well as the decryption keys.
It creates a directory under ProgramData named WMProcess. Then it copies the original WMPDMC.exe from System32 into this newly created folder. Next, it decrypts the embedded payload using the string IRANNUMBERONE as the XOR seed and drops the decrypted payload in the same folder under the name wmpdui.dll.
Using scheduled tasks, the dropper maintains persistence by leveraging the legitimate executable, which will sideload the malicious payload. To make the task appear legitimate, it sets the author to Microsoft Corporation and the description to Collects device metadata for Windows Media Player.. It also sets the boot-trigger delay to PT3M, which corresponds to a 3-minute delay after system startup, and configures the task to run under the Local System account (S-1-5-18).
YobaLoader – wmpdui.dll
The second-stage payload contains the same code as the dropper, which indicates that the same developer is responsible for both components.
The same anti-sandbox technique is used, forcing the malware to be run only by WMPDMC.exe. It again checks the hash of the process basename, and only continues execution if this value matches the hardcoded hash 0x552751E3.
The dropper uses the DJB2 hashing algorithm to hash and verify the process name and to resolve Windows API functions, both with the same seed 0x1505. The loader (YobaLoader) also uses DJB2 for the process name with the same seed as the dropper, but for resolving Windows API functions it uses a different seed, 0x1DEB.
The developer reused the same string-hashing algorithm but changed the seed (0x1505 in the dropper, 0x1DEB in the loader) to separate the hash spaces for each stage, complicating analysis, and reducing the effectiveness of hash-based detection and automated tooling.
Network
The downloader uses an interesting process to obtain the next-stage payload. It first decrypts multiple strings using a simple XOR operation, among these strings is the URL of a Telegram channel, t[.]me/yoba_fanclub. It then visits this channel using the user-agent string Mozilla/5.0 (Windows NT 10.0; Win64;) and parses the HTML source to extract the src URL of the element with the class tgme_page_photo_image. This class refers to the location where the channel’s profile image is hosted.
It downloads the image and uses the last 50 bytes as a seed to generate a domain based on three lists of dictionary words, which are decrypted as part of the DGA algorithm. This DGA algorithm uses three sets of strings:
- Adjectives
- Nouns
- Verbs
Finally, it generates and appends an integer value in the range 0–999. The generated domain has the following format, "$adjective-$noun-$verb-$digit.dedyn[.]io". By changing the image of the Telegram channel, a new domain can be generated.
The following Python snippet represents the DGA algorithm:

print(generate_domain(image_file))
It then queries Google’s DNS-over-HTTPS (DoH) API to obtain an encrypted command from a DNS TXT record, using a URL of the form https://dns[.]google/resolve?name=$DGA&type=TXT.
By relying on a DoH service and common file-hosting platforms, the actor aims to bypass passive DNS monitoring and some gateway-based security protections, making their command-and-control traffic harder to distinguish from regular user activity.
It decodes the Base64-encoded data field from the JSON response and validates it using Ed25519 signature verification with the public key b5c2d20623d4e6647d06a42864edd8629f82c5c384b243fdaeeeca24b3873d64. Once the signature validation succeeds, it decrypts the decoded value using AES in ECB mode with the key 1d0d1368b4d53f3a6322cf40e84e63db.
Decrypted response: 1https://files.catbox[.]moe/z5zpy9.dat
The downloader retrieves the encrypted payload and decrypts it using the same AES key and ECB mode that were previously used for the DNS data.
The malware provides three methods for deploying the downloaded payload. The selected method is indicated by the first character of the decrypted response that follows the URL (1/2/3):
- Injects the downloaded payload into
svchost.exe(NtWriteVirtualMemory/NtCreateThreadEx). It enumerates running processes and, using the hashing algorithm with the seed0x1DEB, searches for the hash value0xC26CDEA5, which corresponds tosvchost.exe. - Saves the payload as a
%TEMP%\$10_rand_char\$10_rand_char.exefile and executes it. Before running the executable, the downloader removes theZone.Identifieralternate data stream, which is hidden metadata used by Windows to track the origin of downloaded files. - Saves the payload as a
%TEMP%\$10_rand_char\$10_rand_char.ps1PowerShell script and invokes it with the following parameters:-WindowStyle Hidden -ExecutionPolicy Bypass -File.
Finally, the injected payload into svchost.exe is an XMRig 6.26.0 miner with a hidden command line targeting a TLS-enabled onion mining endpoint through a local Tor SOCKS5 proxy. It can unpack and start Tor 0.4.9.12 plus lyrebird 0.8.1, monitor user-input activity to pause mining, and conditionally load the WinRing0 driver service for MSR-based mining optimization.

Although we observed an XMRig cryptominer as the final payload in this campaign, the YobaLoader is a generic loader. The operator can supply any PE or PowerShell payload via the signed DNS TXT tasking, so future waves may deliver different malware families.
Past Yoba Versions
Yoba exposes, through the same hashing algorithm it uses for anti-analysis, the specific process name under which it expects to run. Even without having full visibility into the campaign from the very beginning, analysts can still infer which targeted software was used to lure users by correlating this expected process name with the fake AI applications promoted on the associated GitHub repositories and GitHub Pages sites.
| Hash | Process | Product |
|---|---|---|
| 0xE6C2F326 | Setup.exe | ChatGPT & Claude Opus |
| 0x56221573 | Cursor.exe | Cursor AI Coding Agent |
| 0x39DE0DD8 | Unknown | Unknown |
Earlier YobaDropper observed in the wild appeared in early June 2026. In this campaign, the dropper was sideloaded by a process named Cursor.exe (hash: 0x56221573). It remains unclear whether Cursor.exe was a legitimate signed binary. The majority of the functionality in this early variant is consistent with the newer versions of both the dropper and the loader.
YobaDropper shows two main differences between its older and newer versions:
- Unpacking logic: In the oldest version, the buffer is first Base64-decoded and then XOR-decrypted to extract the YobaLoader. In the newer version, the developer removed the Base64-decoding step and performs only XOR decryption, simplifying the unpacking process.
- Execution method: The second change concerns how YobaLoader is triggered. The newer version uses Scheduled Tasks to start the copied legitimate host and sideload the loader, whereas the first discovered version creates the shortcut
msdefender_scheduler{7940-8490-6670-1081}.lnkin the Startup folder. This shortcut executes a copied%APPDATA%\Microsaft Difendir\msdtc.exeand sideloads%APPDATA%\Microsaft Difendir\mswsock.dll.
Earlier version of YobaLoader contains language checks and excludes only Russia from infection. In later versions, these checks were moved to the dropper stage and expanded to exclude additional CIS countries, shifting regional filtering earlier in the infection chain.
While the overall DGA logic remains the same, the early variant uses the extension .aber[.]ir instead of .dedyn[.]io. In addition, instead of injecting into svchost.exe, this variant injects into a different running process identified only by its hashed name 0x21BD94C2.
The initial loader also implements several anti-analysis techniques that have been removed from the newer versions of the malware:
1. Anti-debugging
It enumerates all kernel object types and reads their TypeName values. Each type name is hashed using DJB2 with the seed 0x1DEB until the hash matches 0xCF9EE149, which corresponds to DebugObject. If a DebugObject is found, it indicates that a debugger is or was active, and in that case the malware terminates itself.
2. Anti-VM
The malware uses a VM/sandbox-detection scoring function while running several hardware fingerprinting checks. The maximum score is 6, and the minimum required to continue the infection chain is 3. The checks include:
- Hypervisor-present bit and CPUID timing (via
RDTSCP). - Hypervisor vendor signature string (CPUID leaf
0x40000000). - CPU brand string sanity checks (CPUID leaves
0x80000002–0x80000004). - SMBIOS-based firmware fingerprinting (
GetSystemFirmwareTable–RSMB)
Despite these small differences in early anti-analysis behavior, the Telegram channel and the profile image used as the seed for the DGA remain the same as in the newer variants, indicating that the operator retained the same infrastructure while iterating on the loader’s evasion logic.
Conclusion
The Yoba campaign shows how attackers can use trusted platforms and the current interest in AI tools to distribute malware in a way that looks believable and harmless at first glance. By packaging their code together with well-known software names and hosting it on GitHub, they lower the chances that users or basic security checks will immediately flag the files as suspicious.
Although the underlying techniques are more advanced than typical commodity malware, the main goals remain straightforward: gain a foothold on the victim’s system, avoid easy detection, and then run the attacker’s chosen payload. Organizations should be cautious about installing “AI helpers” or similar tools from unverified repositories and should enforce policies that restrict running software from unknown sources. Combining user awareness with basic technical controls.
