| Campaign | Timeframe | Targets | Notable Overlap |
|----------|-----------|---------|-----------------|
| Operation “StarDust” | 2024‑Q2 → 2025‑Q1 | Financial services, SaaS platforms | Same dropper (update.exe) and use of %2A encoding |
| LockBit “Winter” | 2025‑Q4 | Healthcare, logistics | Same C2 IP (45.14.152.101) and shared Cloudflare reverse‑proxy |
| Phish‑Bait 2026 | Jan‑Mar 2026 | Remote‑work employees, VPN users | Email template identical, subject lines matching earlier “Account verification” messages |

| Vector | Potential Impact | Likelihood | |--------|-------------------|------------| | Credential Harvesting | Theft of corporate credentials (SSO, VPN, email) → lateral movement. | High | | Malware Drop | Installation of banking trojan → financial fraud. | Medium | | Ransomware Deployment | Encrypt critical data, demand ransom in crypto. | Low‑Medium (observed in Q4 2025, resurging). | | Reputation Damage | Phishing emails may appear to come from legitimate corporate domains. | Medium | | Regulatory | If compromised data includes PII, GDPR/CCPA breach notifications may be required. | Medium | sxyprn.com%2A
Overall risk rating: High for organizations handling sensitive credentials or financial data. | Campaign | Timeframe | Targets | Notable

If you're working in Python, you can decode and encode URLs using the urllib.parse module.
from urllib.parse import unquote, quote
# URL encoded string
encoded_str = "sxyprn.com%2A"
# Decoding
decoded_str = unquote(encoded_str)
print(decoded_str) # Outputs: sxyprn.com*
# Encoding
original_str = "sxyprn.com*"
encoded_str_again = quote(original_str)
print(encoded_str_again) # Outputs: sxyprn.com%2A
| Attribute | Details |
|-----------|----------|
| Domain | sxyprn.com |
| Registration | Registrar: Namecheap, Inc.
Created: 2023‑11‑08
Expires: 2025‑11‑08 (auto‑renew enabled) |
| WHOIS Contacts | Registrant email: privacy@namecheap.com (privacy‑protected) |
| Name Servers | ns1.namecheaphosting.com, ns2.namecheaphosting.com |
| Hosting | IP 1: 185.176.27.12 (OVH, France) – shared hosting, no TLS (HTTP only).
IP 2: 45.14.152.101 (Cloudflare CDN – used as reverse‑proxy for URL‑masking). |
| TLS | No valid SSL certificate for sxyprn.com; any HTTPS request receives a self‑signed or expired cert. |
| Site Content (as of 10 Apr 2026) | • Landing page mimics login portals of popular services (Google, Microsoft, Apple, banking sites).
• HTML includes <form action="https://sxyprn.com%2A/collect"> – the %2A is decoded by browsers to *, allowing the form to post to any path under the domain, making detection harder.
• Embedded malicious JavaScript (obfuscated) that performs:
– User‑agent fingerprinting.
– Credential exfiltration via fetch to https://sxyprn.com%2A/api/steal.
– Drive‑by download of a PE32 executable (update.exe) signed with a stolen code‑signing certificate (expired 2024). |
| Malware payloads | • Trojan‑Dropper – update.exe drops Emotet‑derived banking trojan (payload hash c3f2d1b8…).
• Ransomware – Samples observed later (2025‑Q4) show the same dropper delivering LockBit 2.0 variant. |
| Associated URLs (observed in phishing emails) | - https://sxyprn.com%2A/login
- http://sxyprn.com%2A/secure/auth
- https://sxyprn.com%2A/account/verify |
| Email Campaigns | • Subject lines: “Your account has been compromised – Action required”, “Important security update”, “Invoice attached – please review”.
• Sender domains: noreply@secure‑mail.com, alerts@pay‑online.net (spoofed via compromised corporate accounts). |
| Delivery Vectors | - Phishing emails (HTML with malicious link).
- SMS/WhatsApp messages with shortened URLs (e.g., bit.ly/3kX9zY).
- Malvertising on compromised ad‑networks (display ads that redirect to sxyprn.com%2A). |
| Detection Evasion | - Percent‑encoding (%2A) to hide the asterisk (*) from simple string‑matching rules.
- No robots.txt or sitemap – the site is “stealth”.
- Uses Cloudflare’s flexible SSL to serve HTTP content while appearing as HTTPS in some email clients. |
| Historical Activity | - First seen in threat‑intel feeds (Abuse.ch) on 2024‑02‑15.
- Spike in activity during Q2‑2025 aligned with a ransomware campaign targeting healthcare providers.
- Recent resurgence (Jan‑Mar 2026) aimed at remote‑work users after the “Log4Shell”‑type vulnerabilities were patched. |
