Researchers reported that HijackLoader is being distributed through pirated software download lures, with victims redirected across multiple domains before retrieving MEGA-hosted archives containing a staged loader. The campaign was not limited to a single piracy site; investigators said similar cracked-software promotions also appeared on platforms such as TIDAL, broadening the reach of the infection chain.
The analyzed sample used a hijacked DLL, encrypted configuration files, and layered evasion techniques including module stomping, stack spoofing, syscall indirection, anti-analysis checks, and unhooking routines. After establishing persistence and attempting UAC bypass, the malware used multiple process-injection paths to deploy a final payload, with LummaC2 identified as the most commonly observed payload in recent activity, although HijackLoader has previously delivered other malware families as well.

Trellix published an analysis of a HijackLoader infection chain in which users seeking pirated software were redirected through multiple domains to a MEGA-hosted archive that deployed a staged loader. The report detailed techniques including DLL hijacking, encrypted configuration files, module stomping, stack spoofing, syscall indirection, anti-analysis checks, unhooking, persistence, UAC bypass logic, and delivery of a final payload such as LummaC2.

Threat actors distributed **LummaStealer** through two social-engineering chains that targeted users seeking pirated software or attempting to pass fake verification prompts. One campaign, active since at least December 2024, used GitHub repositories, cracked-software forums, URL shorteners, and posts on platforms including Facebook, Devpost, TikTok, and Chromium issues to push victims toward malicious JavaScript. That script suppressed referrer leakage, captured page-title context, and redirected users through intermediary domains on `.cfd`, `.click`, `.info`, and `.xyz` before serving password-protected archives from **MEGA** that extracted a LummaStealer executable. A separate delivery chain used counterfeit **CAPTCHA** pages to trick users into opening the Windows Run dialog and pasting a PowerShell command that fetched follow-on instructions from a shortened URL, downloaded a ZIP archive from `vultrcdn[.]com`, and launched a disguised `Setup.exe`. The infection sequence relied on legitimate-looking or signed binaries such as a revoked `Mergecap.exe`, a renamed `BtDaemon.exe` as `StrCmp.exe`, `more.com`, and `searchindexer.exe`, indicating DLL sideloading and process injection for evasion. Investigators observed outbound traffic to suspicious domains including `accentypastedw[.]store` and `onefreex.com`, while analysis of the final payload showed infostealer behavior including scheduled task creation, cryptographic API use, timestamp tampering, and file-permission changes.

**Lumma Stealer** continued to expand as a prolific malware-as-a-service infostealer, with researchers reporting sharp growth in detections and increasingly diverse delivery chains. Microsoft attributed the malware and its command-and-control ecosystem to **Storm-2477**, which operates Lumma for affiliates that build payloads and run campaigns through a management panel. ESET reported Lumma detections surged **369%** in late 2024, while additional reporting from Netskope and other researchers highlighted ongoing **fake CAPTCHA/ClickFix** lures and fresh payload variants designed to evade detection. Observed campaigns used multiple infection paths, including phishing, malvertising, compromised websites, trojanized software, abuse of trusted platforms such as GitHub, and delivery by other malware including **DanaBot**. Microsoft described an early-April campaign that combined **EtherHiding** hosted through Binance Smart Chain smart contracts with ClickFix social engineering, and an April 7 campaign targeting Canadian organizations that used **Prometheus TDS** redirection plus `mshta` and PowerShell stages to deploy Lumma alongside **Xworm**. The malware was reported stealing credentials and cryptocurrency wallets, using process injection and hollowing, and relying on layered infrastructure with hardcoded domains and fallback channels through **Steam** and **Telegram** behind Cloudflare; Microsoft said its disruption effort led to the takedown, suspension, or blocking of about **2,300 malicious domains** tied to Lumma operations.

Researchers documented multiple **Lumma Stealer** infection chains that begin with fake CAPTCHA or verification pages and trick Windows users into launching malicious PowerShell from the Run dialog. In one case, victims reached the lure through malicious pop-up ads on a pirated-content site; in another, a page at `you-checked.com` copied a hidden command to the clipboard that fetched follow-on payloads from domains including `ferrydero.com` and `fill-tomap.com`. The malware family, also known as **LummaC2**, is a malware-as-a-service infostealer designed to steal browser data, credentials, cryptocurrency wallets, session tokens, and other sensitive information. The observed chains used `mshta.exe`, obfuscated HTA and JavaScript, layered PowerShell stages, and multiple packed .NET components to retrieve and execute the final payload while evading analysis. Analysts reported AES and XOR decryption, SmartAssembly and .NET Reactor packing, AMSI bypass attempts, anti-sandbox and anti-debugging checks, Windows Defender evasion, and cleanup steps such as deleting downloaded archives after execution. One intrusion created files under `C:\ProgramData`, contacted `iplogger.co`, and launched an infostealer executable named `jegule.exe`, while another sample ultimately communicated through `winhttp.dll` and `ws2_32.dll`; investigators also recovered additional URLs from a Steam Community profile using ROT15 decoding.
