Emergency Server Review

When to Request an Emergency Review

An Emergency Server Review is for active or suspected security incidents on your Linux server. If any of the following apply, you should request an emergency review immediately:

• Server sending spam — your mail queue is flooded, your IP is being blacklisted, or your hosting provider has notified you of outbound abuse
• Blacklisted IP — your server’s IP appears on Spamhaus, Barracuda, SORBS or other major blacklists, affecting mail delivery or reputation
• Malware detected — antivirus, hosting provider or a third party has flagged malicious files on your server
• Cryptominer running — unexplained high CPU usage, unknown processes consuming resources
• Web shells found — suspicious PHP, Perl or Python scripts in your web directories providing remote access to attackers
• Brute force success — evidence of successful unauthorized login via SSH, control panel or application
• Unknown processes — processes running under unexpected users, connecting to unknown external hosts
• Data exposure — customer data, credentials, database dumps or configuration files found accessible or leaked
• Defaced website — web content modified by an unauthorized party
• Hosting provider warning — abuse notification, suspension threat or traffic anomaly alert from your provider

What We Do

We treat emergency reviews as priority engagements with a structured, rapid response:

• Immediate triage — assess the scope and severity of the incident, identify the most critical risks, determine if the server is actively being exploited
• Root cause analysis — trace the attack vector, identify how access was gained, determine the timeline of compromise
• Containment guidance — recommend immediate steps to stop active abuse without unnecessary disruption (isolate compromised accounts, block malicious IPs, disable exploited services)
• Log review — examine auth logs, web access logs, mail logs, cron logs and system journals for indicators of compromise, lateral movement and persistence mechanisms
• Malware and backdoor check — scan for web shells, rootkits, cryptominers, modified system binaries, suspicious cron entries, unauthorized SSH keys and hidden processes
• Mail abuse analysis — review mail queue, outbound patterns, authenticated senders, PHP mail usage and blacklist status for spam-related incidents
• Urgent report — deliver findings as quickly as possible with immediate action items

What You Receive

• An emergency incident report with findings, timeline and root cause analysis
• Prioritized remediation steps ordered by urgency
• Containment actions already recommended during the review
• Indicators of compromise (IOCs) identified on your server
• Guidance on blacklist delisting where applicable
• Post-incident recommendations to prevent recurrence
• Follow-up consultation to discuss findings and next steps

Response Time

We aim to begin emergency reviews within hours of engagement, depending on current availability. Once we start, we work on the incident continuously until the initial triage and urgent findings are delivered.

For guaranteed SLA-backed response times, ask about our priority support arrangements.

Pricing

Emergency Server Reviews start from 650 EUR + VAT, depending on incident scope and server complexity. The final price is confirmed after an initial assessment of the situation.

Contact us immediately to start an emergency review.

After the Emergency

Once the immediate incident is resolved, we strongly recommend a full Linux Server Audit to identify and close any remaining security gaps. Compromised servers frequently have multiple weaknesses — the exploited vulnerability is rarely the only one.

We also offer Server Hardening Reviews to bring your server up to a secure baseline after remediation.

For incidents involving broader infrastructure (DNS hijacking, cloud account compromise, multi-server breaches, CDN or domain-level attacks), see YourInfraAudit.com for infrastructure-wide emergency response.
