Emergency SQL Injection Cleanup & Database Recovery

An SQL injection backdoor is a persistent database object—such as a malicious stored procedure, trigger, or rogue administrator account—that allows attackers to regain database access even after the original vulnerability is patched. These backdoors execute attacker code, exfiltrate data, or recreate compromised access on demand. We systematically locate and remove all backdoor mechanisms while closing the original injection vector.

No security service can guarantee zero data exfiltration without comprehensive forensics. However, we provide detailed evidence including log analysis, network traffic review, and attack timeline reconstruction to estimate the exposure window and likely data accessed. This information supports your breach notification decisions and regulatory filings. Our forensic reports document what we can prove was compromised versus what might have been accessed.

No. We only remove identified malicious artifacts like injected spam rows, backdoor stored procedures, rogue accounts, and malicious triggers. All operations are transaction-safe with rollback protection, and we preserve complete snapshots before any changes. Legitimate business data remains intact throughout the remediation process. If data restoration from backups is needed, we carefully reconcile to preserve recent valid transactions.

Emergency triage typically starts within 1-4 hours for urgent cases involving active data exfiltration or critical systems. We prioritize based on threat severity, data sensitivity, and business impact. Initial containment actions (blocking IPs, deploying WAF rules) can begin within the first hour. Complete remediation including code fixes and verification takes 1-7 days depending on database complexity and application architecture.

We remediate SQL injection across all major platforms: MySQL/MariaDB, PostgreSQL, Microsoft SQL Server, Oracle Database, SQLite, and NoSQL systems like MongoDB, Cassandra, Redis, and Elasticsearch that support query-based attacks. Our security engineers have deep expertise in database internals, stored procedure languages, and platform-specific security features for each system.

We include supply chain security review as part of our investigation. If a third-party component is the vulnerability source, we coordinate vendor patching, implement temporary mitigations via WAF virtual patches, or recommend component replacement with secure alternatives. We also assess whether vendor notification triggers coordinated disclosure obligations and assist with that communication.

Our verification process includes: cryptographic hash comparison of critical records against clean backups, relational integrity checks ensuring foreign key consistency, business rule validation (e.g., order totals matching), checksum verification across tables, and QA testing of critical workflows. We document all verification steps and provide attestation of data integrity restoration suitable for audit purposes.

Yes. We provide technical documentation supporting GDPR, CCPA, HIPAA, and state breach notification requirements including attack timelines, scope analysis, exposure estimates, and remediation evidence. We coordinate with your legal counsel to prepare notification content, work with payment card forensic investigators for PCI breaches, and communicate technical details to regulators and third parties as needed.

We replace all vulnerable dynamic SQL with parameterized queries and prepared statements, implement strict input validation using whitelist patterns, deploy secure query builders or ORM frameworks (Entity Framework, Hibernate, Sequelize), enforce least-privilege database accounts, add static analysis security testing (SAST) to development pipelines, and provide code review training ensuring your team maintains secure practices going forward.

Post-remediation monitoring includes: database query pattern analysis detecting anomalies, Web Application Firewall (WAF) tuning and alert review, regular security scanning for new vulnerabilities, audit log review identifying suspicious activity, performance baseline monitoring detecting resource abuse, and periodic penetration testing ensuring injection vectors remain closed. We provide monthly reports showing security posture and any detected threats.
