 Executive Summary

• BaoLoader is a modern malware loader being leveraged by multiple ransomware gangs and infostealer operators.
• Similar to HijackLoader, BaoLoader’s role is initial infection and payload delivery.
• Campaigns in 2025 show active distribution via malspam, cracked software, and SEO poisoning.

---

 Technical Deep Dive

• Loader Functionality:
  • Deploys payloads like ransomware, banking trojans, and stealers.
  • Uses obfuscated PowerShell, DLL sideloading, and API calls.
• Infection Vectors:
  • Spam campaigns with ZIP/OneNote attachments.
  • Malicious ISO and MSI installers.
  • Weaponized cracked apps (games, productivity software).
• Persistence & Evasion:
  • Registry run keys, scheduled tasks.
  • Anti-VM and sandbox evasion.
  • Encrypted config & randomized C2 traffic.

 Vulnerabilities & CVEs Exploited

• BaoLoader doesn’t rely on a single exploit but often chains with CVEs in Office, Windows SMB, and browser engines.
• Examples:
  • CVE-2025-55234 (Windows SMB Relay)
  • CVE-2025-8088 (WinRAR zero-day)
  • Old macros/ActiveX flaws exploited for loader delivery.

---

 Global Impact

• Ransomware operators (KillSec, DarkCloud) increasingly using BaoLoader.
• Crypto theft campaigns — loaders drop Maranhão Stealer or Agent Tesla.
• Geopolitical risks — loader infrastructure traced to East European groups.

---

 Indicators of Compromise (IOCs)

• Hashes of BaoLoader samples.
• Typical file names (invoice_2025.docx, voicemail.zip).
• C2 domains over HTTPS & Telegram bots.
• Registry entries for persistence.

---

 Mitigation & Defense

• Block common file extensions in email (.one, .iso, .msi).
• Disable macros & legacy ActiveX.
• Deploy EDR with behavioral detection rules for loader patterns.
• Monitor for anomalous PowerShell execution.

---

 Case Studies

• Finance firm hit by ransomware after BaoLoader delivered KillSec payload.
• Healthcare organization — credentials stolen by Maranhão Stealer dropped via BaoLoader.

---

 CyberDudeBivash Recommendations

• Patch all CVEs in the loader’s exploit chain.
• Segment networks to contain ransomware spread.
• Run SOAR playbooks for suspicious file execution.
• Conduct red team phishing simulations with voicemail/loader lures.
