TRINITY CYBER // THREAT LAB
Explore real-world threat scenarios that demonstrate Trinity Cyber's Full Content Inspection capabilities. Includes SHA256 hashes, MITRE ATT&CK mappings, and detailed analysis of how each threat is neutralized inline.
TrustConnect Campaign: EV-Signed RMM Backdoor (March 2026)
Threat actors distributed phishing emails with PDF attachments directing victims to download malicious executables masquerading as Microsoft Teams, Zoom, Adobe Reader, and Google Meet installers. The executables were digitally signed with a stolen Extended Validation (EV) certificate issued to 'TrustConnect Software PTY LTD,' bypassing Windows SmartScreen and most endpoint detection.
Deep binary inspection of signed executables during download; detection of malicious behavior signatures inside EV-signed binaries that endpoint tools trust
XWorm Campaign: Steganography via Cloudinary-Hosted Image (February 2026)
Attackers sent phishing emails with malicious Excel attachments exploiting CVE-2018-0802. The exploit chain downloaded an HTA file, which executed PowerShell that fetched a JPEG from Cloudinary. Hidden inside the JPEG, between 'BaseStart' and 'BaseEnd' markers, was a Base64-encoded .NET module that performed process hollowing to inject XWorm RAT.
Deep content inspection of image files to detect embedded payloads hidden via steganography; detection of encoded executables appended to legitimate image data
TrustConnect Campaign: PDF Lure Redirecting to Malware Download (March 2026)
A phishing email included a PDF attachment displaying a blurred document with a red 'Open in Adobe' button. Clicking redirected to a spoofed Adobe download page serving the malicious signed executable. The PDF is the initial attack vector that Trinity Cyber can inspect and neutralize inline.
Deep inspection of PDF document structure to detect and neutralize embedded malicious URLs and JavaScript actions; replacement of weaponized PDFs with sanitized versions
Residential Proxy Botnet via Lookalike Domain (February 2026)
A convincing lookalike of the 7-Zip website (7zip.com instead of 7-zip.org) served a trojanized installer that silently converted victims' machines into residential proxy nodes. The installer was functional — it actually installed 7-Zip — but included a hidden proxy agent running as a background service.
Detection of trojanized executables that bundle legitimate software with hidden malicious components; binary-level inspection that identifies proxy/botnet agents embedded within otherwise functional installers
Malicious OLE Object Exploiting CVE-2018-0802 (February 2026)
The initial delivery document from the XWorm campaign. The Excel file (.xlam) contains a malformed OLE object exploiting CVE-2018-0802 in the Microsoft Equation Editor. When opened, it triggers shellcode that downloads the next stage of the attack.
Deep inspection of Office document internals to detect and remove malformed OLE objects and embedded shellcode; neutralization of exploit payloads within document streams
DLL Side-Loading via Fake GitHub Downloads (March 2026)
Attackers created fake GitHub repositories with SEO-optimized pages offering free software tools. The download was a ZIP containing a legitimate executable and a malicious libcurl.dll that gets side-loaded. The DLL downloads BoryptGrab stealer, Vidar stealer variants, and a reverse SSH backdoor.
Inspection of files within compressed archives (ZIP) during transit; detection of malicious DLLs packaged alongside legitimate executables for side-loading attacks
XWorm Campaign: Multi-Stage Loader Chain (February 2026)
After the initial Excel exploit, the XWorm attack chain downloads an HTA file containing obfuscated JScript with a Base64-encoded PowerShell payload. The PowerShell then downloads the steganographic JPEG. This tests Trinity Cyber's ability to detect and block malicious HTA files during download.
Detection of obfuscated script content within HTA files; identification of encoded PowerShell payloads embedded in JScript; blocking of multi-stage loader chains at the earliest possible point
Use of CertUtil to Evade Network Detection
Attackers hide malicious code inside files that look like security certificates using CertUtil encoding.
Binary content replacement
OLE File with Embedded Equation Object (CVE-2017-11882)
A vulnerability in Microsoft Office's old Equation Editor allows attackers to run code via embedded OLE objects.
OLE object removal
DarkSide Ransomware Evades Detection with Packing
DarkSide ransomware, famous for the Colonial Pipeline attack, uses packing to evade simple signature-based detection.
Packed executable detection
Spoofed Google Analytics Delivers Card Skimming Payload
MageCart attackers compromise e-commerce sites with malicious JavaScript disguised as Google Analytics to steal credit card data.
Script content removal
PNG Files with Embedded Payloads
Steganography hides malicious data within image files. This PNG contains a payload appended after the legitimate image data.
Image payload stripping
Spoofed ECC Certificates within TLS Sessions
The CurveBall vulnerability (CVE-2020-0601) allows attackers to create fake website security certificates that Windows trusts.
TLS session termination
RTF with Embedded RCE Vulnerability (CVE-2012-0158)
An RTF file exploiting CVE-2012-0158, a remote code execution vulnerability in Microsoft Office that remains actively exploited.
Document content replacement
Spoofed ECC Certificates Within Binary Executables
An executable signed with a fake CurveBall certificate to appear legitimate and bypass security controls.
Binary removal
