Server compromised? We regain control before the damage is total.
A server invasion is a violation of the heart of your company. Our Linux/Windows infrastructure specialists eliminate the threat and shield your environment to prevent recurrence.
"CPU usage is constantly pinned at 100%, and unapproved users or background scripts appeared in the OS."
Cryptominers and rogue background tasks hijack compute resources, degrading production applications and maintaining covert persistence on your machines.
Forensic Process Audit & Threat Eradication:
- Exhaustive audit of active processes, memory spaces, listening ports, and sockets
- Identification and surgical removal of hidden web shells and background miner scripts
- Restoration of tampered system binaries and deletion of hostile cron jobs
- Forensic integrity verification report with perimeter traffic isolation
"Management suspects persistent backdoors across exposed SSH, RDP, or remote management ports."
Password-based management ports exposed to the open internet are continuously probed by automated brute-force scripts and credential stuffing engines.
Access Hardening & Perimeter Lockdown:
- Enforcement of key-based SSH authentication with immediate disabling of password logins
- Closure of unnecessary service ports and IP whitelisting for administrative access
- Implementation of aggressive iptables/ufw rate-limiting and automated intrusion bans
- System permission tightening to prevent local privilege escalation exploits
"We fear that the only resolution is wiping the server, causing days of catastrophic operational downtime."
Total machine wipes force costly system reconfigurations and lengthy service disruptions. Our engineers focus on surgical in-place remediation with active business continuity.
Surgical In-Place Remediation:
- Precision sanitization of infected modules without requiring a destructive reformat
- Service containment that preserves critical production databases and application assets
- Security patch deployment with graceful service reloads to avoid user disconnects
- Guaranteed rollback snapshot protection established prior to executing system changes
Digital Hygiene Protocol
Rootkit Detection
Deep scanning at the system level to find camouflaged threats that common antiviruses cannot identify.
SSH & RDP Hardening
We eliminate the #1 cause of invasions by configuring access via public key and limiting ports by geolocation and specific IPs.
Log Monitoring
We implement real-time alerts for any suspicious login attempt or modification of critical system files.
Invasion Questions
Server hardening is the deliberate process of securing a server's operating system, network stack, and hosting environment by systematically minimizing its attack surface and closing unneeded vectors. Default server configurations typically leave administrative ports exposed, run unnecessary background services, and employ permissive user privileges that invite automated brute-force attacks and lateral intrusion.
TAVARDT executes rigorous server hardening protocols across Linux and Windows production environments, implementing custom firewall architectures, SSH public-key-only authentication, fail2ban rate-limiting, and strict kernel-level sysctl parameter optimizations.
Yes, attackers often leave 'backdoors' to return later.
Therefore, our first step is total isolation to cut off any external communication from the attacker.
We use low-level recovery tools and system journal analysis.
If the data has not been physically overwritten, the chances of partial or total recovery are high.
It is the shielding process.
After cleanup, we disable unnecessary services, configure aggressive firewalls, implement secure SSH keys, and remove any known OS vulnerabilities.
Not necessarily. Our goal is surgical sanitization.
However, if the compromise is at the kernel level (rootkit), we recommend migration to a clean and secure instance that we configure from scratch.
