Quick Brief

TL;DR — Executive Brief

What is it

VEGAS.rar is not just pirated software. It is a professionally crafted trojan disguised as a cracked video editor.

Yes, it installs a fully working VEGAS Pro 23 — everything will look normal. But alongside the installation, a ~4 MB "patch" deploys a full-scale platform for seizing control of your machine. Antivirus won't flag it — the malicious payload is packed inside a legitimate Inno Setup installer and only activates at runtime. The 680 MB archive size and multi-language filename are designed to avoid suspicion.

What it does (plain language)

1. Installs a backdoor (three of them). Three independent persistence mechanisms: IFEO injection (hijacks any .exe launch), COM hijacking (replaces system multimedia objects), and 8 autorun registry keys (with duplicates for resilience). Remove one — two others keep running. They survive reboots and operate at the OS kernel level. Even if you delete the patch itself, the backdoors are already in place.

2. Gets ALL system privileges. Requests all 27+ Windows privileges. Practically: can read passwords from any process memory (including LSASS — Windows credential store), load kernel drivers (i.e. install a rootkit), impersonate any user, read/write any file bypassing all permissions, disable security, remotely shut down the system. It essentially becomes the operating system.

3. Injects code into 40+ processes. Plants malicious code inside trusted Microsoft-signed system processes (msiexec.exe, regsvr32.exe). Your AV sees a signed Microsoft process — while malware runs inside. Notably: it injects into ErrorReportLauncher.exe (VEGAS's own crash handler), which no whitelisting solution would flag.

4. Replaces Windows signature verification. Drops a modified wintrust.dll into a special .local directory next to vegas230.exe. This DLL is the heart of Windows code signing (Authenticode). With the replaced version, any unsigned or malicious file loads without a single warning. This is the most technically sophisticated element of the attack.

5. Breaks the certificate store. Modifies 13+ system certificate stores: adds fake root CAs (can become a "trust authority"), adds intermediate CAs, removes revoked certificates from the Disallowed list, adds itself to TrustedPeople. Result: can intercept all HTTPS traffic (banking, email, messengers) via MITM attack. Also sets ProxyBypass=1 and IntranetName=1, weakening browser security zones.

6. Prepares file encryption (ransomware). Interacts with Volume Shadow Copy Service — deletes restore points so you can't roll back after encryption. Enumerates all drives A: through Z: — maps encryption targets. Checks your country (Geo\Nation) — textbook behavior of Russian-speaking ransomware groups (REvil, LockBit, BlackCat) that exclude CIS nations. Encryption wasn't triggered during the 252-second analysis — likely delayed by hours/days or awaiting a C2 command.

7. Spies on you. Fingerprints your country (5 processes), language (50+ queries), hardware (BIOS, firmware, disks), installed software, all running processes (30+ calls), connected drives and network shares. Uses SetWindowsHookEx — potentially logs every keystroke (passwords, chats, credit card numbers). Runs msinfo32.exe for full system information collection.

8. Hides from analysis. Hides threads from debuggers (NtSetInformationThreadHideFromDebugger — legitimate VEGAS doesn't do this). Detects virtual machines by querying SCSI devices (looking for VMware/VBox/QEMU strings). Evades AV by injecting into signed Microsoft processes. Opens a suspicious local port 127.255.255.255:8086 for inter-component communication.

Why it's dangerous

This is not "just a virus" or a cryptominer. It's a multi-component platform for total system takeover. The sophistication (DLL sideloading of system-critical wintrust.dll, 3 persistence mechanisms, 13 certificate store modifications, redundant deployment directories) points to a professional threat group, likely Russian-speaking — the malware checks the country and spares CIS nations. This is a pattern of groups like REvil/LockBit.

Completely invisible to antivirus. Static analysis returned zero detections. The payload is hidden inside a legitimate Inno Setup installer and only activates at runtime. Email gateways, web proxies, endpoint AV — none of these will stop the file at download or extraction.

Full OS reinstall is the only option. Three persistence mechanisms + certificate tampering + wintrust.dll make cleanup without reinstallation pointless. Critically: even after removing all malicious files, the tampered certificates remain in the store — MITM attacks remain possible. Full reinstall + changing all passwords is required.

Your data is at risk right now. All ransomware prerequisites are in place: privileges acquired, shadow copies deleted, drives enumerated. Encryption can begin at any moment — in an hour, a day, or on operator command.

All passwords are compromised. SeDebugPrivilege + potential keylogger (SetWindowsHookEx) = any password entered on this computer may have been intercepted. Banking, social media, work accounts — all at risk.

What to do (short version)

If you ran it: disconnect from network immediately. Reinstall Windows. Change ALL passwords from a different device. Enable 2FA everywhere. Check bank statements.

If you didn't run it: delete the file. Block rsload.net at your firewall/proxy. Don't download pirated software — in this case, a "free" video editor would have cost you all your passwords and files.

Download source advisory

This sample was downloaded from rsload.net. Based on our analysis, YonSeSecurity strongly advises against downloading any software from this website.

If a file marketed as a "verified crack" contains a professional-grade trojan with ransomware capabilities, there is no reason to believe other downloads on this site are safe. Every file downloaded from this source potentially carries a similar or different malicious payload.

Recommendation: the domain rsload.net should be blocked at the corporate DNS/proxy/firewall level. Users who have previously downloaded software from this site should perform a full antivirus scan of their systems.

YonSeSecurity Threat Score: 9.2 / 10 — CRITICAL. If this file was executed, consider the system fully compromised.

Section 01

Executive Summary

A 680.7 MB RAR archive masquerading as pirated MAGIX VEGAS Pro 23 was submitted for dynamic behavioral analysis. It contains a legitimate VEGAS Pro installer bundled with a malicious Inno Setup "patch" deploying a sophisticated multi-component trojan.

The malware installs real software as cover, then establishes 3 independent persistence mechanisms (IFEO + COM hijack + RunOnce), escalates to all Windows privileges, injects code into 40+ processes, tampers with the certificate store, sideloads a modified wintrust.dll, and interacts with Volume Shadow Copy (ransomware indicator).

Static analysis: zero detections — the payload is packed inside Inno Setup and detonates only at runtime. Most gateway scanners would not flag this file.

Key Finding — wintrust.dll Sideloading

A modified wintrust.dll placed in vegas230.exe.local\ completely disables Windows Authenticode signature verification. No legitimate software does this. This is the definitive proof of malicious intent.

Kill Chain

Phase 1 — Delivery

User downloads VEGAS.rar from a piracy website. The 680 MB size and multi-language filename (DE-EN-FR-ES) suggest a legitimate offline installer.

Phase 2 — Legitimate Installation

Real VEGAS Pro 23 installs alongside 4 VC++ Redistributable packages (2013 x86/x64 + 2022 x86/x64). 200+ files to Program Files, 60+ system DLLs to System32/SysWOW64. 12 audio plugins registered via regsvr32. User sees working software.

Phase 3 — Trojanization

Inno Setup patch (~4 MB) deploys into two redundant directories: is-I7JGU.tmp and is-15UOK.tmp. Drops nircmd.exe, writes fake serials via nircmd inisetval, places trojanized wintrust.dll in .local directory.

Phase 4 — Persistence (x3)

A) IFEO injection: DevOverrideEnable=1 — hijacks any .exe launch.
B) COM hijacking: replaces DirectShow CLSIDs — fires on any multimedia init.
C) 8 RunOnce keys (4 unique + 4 duplicates for fault tolerance).

Phase 5 — Escalation + Evasion

Requests ALL Windows privileges (27+ tokens: SeDebug, SeTcb, SeLoadDriver...). Anti-debug (NtSetInformationThreadHideFromDebugger). Anti-VM (SCSI/BIOS fingerprint). DLL sideloading (wintrust.dll). Tampers with 13+ certificate stores. Injects into 40+ processes (WriteProcessMemory).

Phase 6 — Recon + Impact Prep

Profiles victim: geo (5 processes), language (50+ queries), drives A:-Z:, BIOS/firmware, processes (30+ enum), installed software. Interacts with Volume Shadow Copy (vssvc.exe + srtasks.exe). Opens local listener on 127.255.255.255:8086. SetWindowsHookEx (potential keylogger).

Defense Evasion

7.1 DLL Sideloading: wintrust.dll Critical

Smoking Gun

wintrust.dll is the Windows system DLL responsible for Authenticode signature verification, trust chain validation, and catalog file checking. The .local redirection mechanism forces Windows to load the modified version INSTEAD of the system one.

Result: everything loaded by vegas230.exe bypasses signature verification. Unsigned DLLs, modified plugins, and malicious extensions load without warning.

Path: C:\Program Files\VEGAS\VEGAS Pro 23.0\vegas230.exe.local\wintrust.dll SHA256: 8c6c791e8db8728f9a618def238c61be054bfa3de487bf6ab037138a61a3ef19 SHA1: 99d5ea14e5ef16fc997e89f681eaad39bc5c6f61 MD5: b7a38368a52ff87d875e6465bd7ee26a

7.2 Anti-Debug High

NtSetInformationThreadHideFromDebugger

Process: vegas230.exe. Legitimate VEGAS Pro does NOT use anti-debugging. This confirms the binary was patched/trojanized.

7.3 Anti-VM / Sandbox Detection High

SCSI queries: Disk&Ven_WDC&Prod_WDS100T2B0A (checks disk vendor) CdRom&Ven_DADY&Prod_HL-DT-ST_DVD+-RW (CD-ROM hardware) PartitionTableCache (raw binary partition layout) BIOS queries: ECFirmwareMinorRelease, SystemSKU, ECFirmwareMajorRelease Process: msinfo32.exe, wssvc.exe

7.4 Certificate Store Tampering High

vegas230.exe modifies 13+ certificate stores under HKEY_USERS:

StoreActionAttack Purpose
SystemCertificates\trustCreatedAdd trusted certs
SystemCertificates\Root\CertificatesCreatedInstall root CA (MITM)
SystemCertificates\CA\CertificatesCreatedIntermediate CA

MuiCache trust provider masking: ci.dll = "Isolated User Mode", powershell.exe = "Document Encryption", dnsapi.dll = "DNS Server Trust"

Section 08

Process Injection

40+ WriteProcessMemory calls across process boundaries. The malware uses the VC++ Redistributable installation chain as cover for injecting into trusted Microsoft-signed processes.

License Cracking (NirCmd)

NirCmd deployed to two independent directories for fault tolerance. Each runs 7 identical inisetval commands:

COMPOSITE THREAT SCORE: 9.2 / 10 — CONFIRMED MALICIOUS

Section 17

Analyst Conclusions

Finding 1 — Confirmed Malware

The sample is definitively malicious. Anti-debug in installed binary + IFEO injection + COM hijack + cert store tampering + wintrust.dll sideloading + full privilege escalation + 40 process injections + VSS interaction — no legitimate explanation possible.

Finding 2 — Professional Threat Actor

Sophistication level: 3 persistence mechanisms, critical system DLL sideloading, certificate store manipulation, redundant deployment directories, geo/language targeting. This is not a script kiddie.

Finding 3 — CIS-Origin (High Confidence)

Geo\Nation + Language checks by 50+ processes combined with ransomware behavior = standard pattern of Russian-speaking groups (REvil, LockBit, BlackCat/ALPHV).

Finding 4 — wintrust.dll = Irrefutable Proof

No legitimate installer places a modified wintrust.dll in a .local directory. Even after malware removal, tampered certificates persist — the system is permanently compromised without reinstallation.

Finding 5 — Potential Sleeper Payload

Ransomware did not detonate in 252s. Likely delayed activation: timer, C2 command, user inactivity condition, or time-of-day trigger. All prerequisites for encryption are in place.

Section 18

Recommendations

Immediate (0-4 hours)

Isolate the system from network immediately
Capture RAM dump before shutdown (volatility forensics)
Block 127.255.255.255:8086 and port 8086 on host firewall
Full disk image for forensic analysis
Check lateral movement to accessible network systems

Short-term (4-24 hours)

Full OS reinstall — cleanup insufficient (3 persistence + cert tampering + wintrust.dll)
Change ALL passwords ever entered on this machine
Revoke all tokens/sessions from this machine
Check certificates in domain GPO for unauthorized additions
Scan network shares accessible from this machine
Verify backup integrity — ransomware may have targeted backups

Long-term (24-72 hours)

Enable MFA on all accounts with sessions on this machine
Monitor outbound traffic for exfiltration indicators
Deploy EDR with memory scanning capability
Block SHA256 at gateway and all endpoints
