Since CTX Team's earlier coverage of this operation, six new files have surfaced that materially deepen the picture of how the Godzilla Loader and PonyStealer campaign targeting Pakistan actually functions — not just what it delivers, but how it gets there. The new components introduce a second build cluster absent from prior analysis: a batch-script orchestrator, an invalid-signed SOCKS5 proxy tool, a PEiD-packed .NET spreader, and a delivery archive built around a keygen lure that has been…

Thirty-nine days. That is the total operational window separating the moment a Sectigo Extended Validation certificate was issued to an entity called QUANTIS LOGIK LTD and the moment the two PE32 installers it signed first appeared on VirusTotal. The certificate — serial number 00 86 51 B4 B7 A5 AF 08 DF 82 E5 FE 4E 5B 99 A8 18, thumbprint 1080D4CCFE6E5EE372CB3DB8686C37923A932AF5, issued 2026-04-22, used to sign both payloads on 2026-05-19, with the files submitted on 2026-06-01 — was not a…

Three command-and-control domains registered within five weeks of each other, scoring zero detections across 91 antivirus engines, with WHOIS identity fields uniformly padded with the same 16-character hex string — this is the operational signature CTX Team has mapped to a TA505-attributed rockloader campaign currently targeting financial-services organisations in Cambodia and Singapore.

A Windows executable branded as a system-cleaning utility — product name "YCleanner," internal name YC.exe, version 1.3.2.5 — has been circulating as the delivery vehicle for a dual-purpose attack chain combining LummaStealer credential theft with XMRig cryptomining, targeting Romania.

Pirated creative software has long been a reliable vector for commodity malware, but a campaign CTX Team has been tracking shows how far that distribution model has matured. Two oversized Windows executables — both named FireflyAI.exe, one weighing 45 MB and the other 53 MB — are circulating as trojanised installers for Adobe's Firefly AI tool, with one sample's embedded path string explicitly referencing "Firefly AI 25.0.0.2265 beta for Adobe Photoshop 24.7 (x64)."

Four German-hosted websites — three of them registered between 2000 and 2009, all of them delegating DNS through the same Cronon/Strato nameserver infrastructure — are serving as the distribution backbone for an active Emotet campaign targeting the hospitality sector in Papua New Guinea.

A 56-kilobyte Windows executable first submitted to VirusTotal in February 2013 is still being resubmitted and tracked as an active threat as recently as March 2025 — and the infrastructure supporting it has grown fresher, not older. The implant at the centre of this campaign is Nemim, a multi-role trojan attributed by CTX Team to DarkHotel and directed at espionage targets in India.

A PE32 dropper bearing a self-signed "FileZilla FTP Client" code-signing certificate — its validity start date of 2025-12-24 matching, to the day, the registration date of the campaign's C2 domain filezilla.cc — sits at the centre of a multi-stage XMRig cryptominer delivery chain that CTX Team has tracked from January through June 2026.

Three unsigned Win32 loaders — the oldest first appearing in December 2020, the newest surfacing in November 2023 — share one imphash, an identical PE section layout down to the byte, and a forged compile timestamp of 1992-06-19 that predates Windows 95. All three carry the same fake product string, "Synaptics Pointing Device Driver," version 1.0.0.4, and two of them drop to the identical path, C:\ProgramData\Synaptics\Synaptics.exe.

Fifteen signed Windows executables. Five distinct Chinese company identities. One commercial certificate authority. A single cert serial binding nine of those payloads to a three-year production window that is still running. The operation CTX Team has been tracking targets the telecom sector and exploits a structural weakness that most enterprise endpoint stacks have not solved: when a binary carries a valid, trusted code-signing certificate, a significant fraction of the detection stack simply…

Three Windows executables are circulating through software download channels carrying code-signing certificates that, by any standard enforcement logic, should stop them cold. One bears a DigiCert leaf certificate for an entity called VOICEFIVE, INC that expired on 3 April 2026. The other carries a Certum Extended Validation certificate for "AN Soft" that has been explicitly revoked.

Sixteen malicious Windows executables and DLLs are currently circulating under valid DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1 certificates — each certificate issued to a distinct Chinese-registered legal entity, each carrying a three-year validity window, and each actively suppressing the dynamic analysis environments that defenders rely on to catch what static signatures miss. The operation is not a single rogue certificate.

A single domain registered in October 2017 — idyllicdownload.com, acquired through Silver Domain Names LLC and abandoned within a year — has emerged as the confirmed network checkin endpoint for a pair of NSIS-packaged OutBrowse adware installers that masquerade as the KMSPico Windows activation crack. The domain's addition to the indicator catalog closes the delivery-to-C2 loop on a campaign attributed to Red Apollo, the China-aligned threat actor also tracked under the aliases APT10,…

When a user downloads what appears to be a Windows client for ChatGPT from chatgpt-windows.top — a domain registered on 2025-06-03 and already flagging 13 of 91 engines on VirusTotal — they receive something considerably more complex than a VPN application. CTX Team's analysis of this campaign reveals a layered abuse chain in which trojanized VPN installers branded as WireVPN and VPNMaster silently co-install a Dotfuscator-obfuscated .NET component signed by Bright Data Ltd that two independent…

Eleven distinct PE files — DLLs and installer EXEs alike — all bearing the same unrevoked leaf certificate issued to a single Beijing-registered technology company. A second Chinese entity in Chengdu holding its own valid DigiCert credential, and a third Chengdu firm with a third.
