From abuse report I understand your server is DDOS-ing other computers. Can login and check/fix what is wrong. Will need a few hours to completely clean it.

Having witnessed the perilous consequences of a compromised VPS firsthand, I understand the urgency of reinstating your Ubuntu system swiftly and fortifying it against future threats. As an esteemed US-based penetration tester with 7+ years of experience, 5/5 rating, and a proven track record, I am primed to revamp your severely vulnerable Ubuntu VPS. My skillset includes an extensive repertoire of ethical hacking which would be useful in identifying the entry point, purging any malevolent code or files, and reinforcing the infrastructural security. I am proficient with tools like fail2ban, UFW/iptables, ClamAV, rkhunter and ModSecurity - capable of imposing comprehensive health-checks onto your server. In terms of tangible results, you can expect an uncompromised web root and services along with stringent hardening measures that significantly reduce the chances of recurrences. My detailed security report will enumerate the steps involved in eliminating vulnerabilities and provide an informative overview for hosting abuse team. Additionally, to ensure residual protection down the line, I will deliver recommendations that you can promptly implement.

With extensive experience in securing Linux environments, I can swiftly identify the entry point used by the attacker, remove any malicious code, and close the vulnerabilities. Restoring your server using best practices in firewall setup, SSL installation, and overall hardening is my top priority. I will ensure that all necessary tools such as fail2ban, UFW/iptables, and ClamAV are utilized for optimal security. Upon completion, I will deliver a clean web root, detailed hardening steps, a post-cleanup security report for the hosting team, and preventive recommendations for ongoing security. I anticipate that the job will be completed in 3 days, and I am ready to start as soon as we agree to proceed.

Hi, I can help you clean up your compromised Ubuntu VPS and get it back online. I have dealt with similar incidents before — identifying the entry point through log analysis, removing malicious code/backdoors, and then hardening the server properly. Here is my approach: 1. Forensic analysis — review access logs, check for unauthorized SSH keys, inspect web root for injected files/shells, check cron jobs and running processes 2. Clean up — remove all malicious code, backdoors, and unauthorized accounts 3. Harden — configure UFW firewall rules, set up fail2ban, enforce SSH key-only auth, install and configure SSL/TLS, update all packages, set up ModSecurity if Apache/Nginx 4. Document everything — provide a detailed security report you can forward to your hosting provider abuse team, plus prevention recommendations Since you have a full backup, we have a safety net to work with. I can start immediately once you share the incident report and root access. - Usama

@kunalmaharUK

Hi, I went through the attached Abuse report file and this looks like an attempt to port scan, this could be a potential proof of compromised system. I can trace back to the original process, and find the exact source of this behavior and eradicate the same. I will further enhance the security by cleaning the system and implementing the security measures and documenting the same. Please feel free to check out my profile in the cybersec domain

@souravsasmal14

Hi, I can help you clean and secure your Ubuntu VPS properly so your hosting provider can lift the suspension. I’ll review the abuse report, identify how the attacker got in, remove any malicious files or backdoors, and close the vulnerability. Then I’ll fully harden the server — configure firewall rules, secure SSH, install fail2ban, update packages, set up SSL, and ensure the web server is properly protected. You’ll receive a clear security report explaining what happened, what was fixed, and what steps were taken, along with simple prevention guidelines for the future. Once you share root access and the backup, I can start immediately and work toward getting the VPS reinstated safely.

@Sbwinwin6000

Hello, I’ll take a careful, low-risk approach to patching your Ubuntu VPS and restore service securely so the abuse team can see a clean, hardened system. With your recent backup, I’ll start by validating the incident report, isolating the compromised components, and then removing any malicious code while preserving legitimate data. I’ll reinstall and harden: firewall rules (UFW/iptables), SSL/TLS certificates, updated packages, secure SSH settings, and proactive monitoring (fail2ban, ModSecurity, ClamAV/rkhunter as needed). I’ll clean the web root for Apache/Nginx, verify config integrity, and ensure the chosen stack is hardened end-to-end. Deliverables include a post-cleanup security report you can share, a documented hardening checklist, and actionable prevention recommendations. I’ll work with your backup to verify a safe rollback path if needed and will proceed only with your authorization. Best regards!
