We specialize in OpenCart cleanup — from payment skimmers to backdoors, SEO spam, and admin takeovers across all OpenCart versions.
OpenCart is one of our most-requested cleanup platforms. The typical OpenCart infection involves injected PHP in /catalog/controller/ or /admin/controller/ directories, modified checkout/checkout.php templates with payment skimmer JavaScript, database injection into oc_product_description and oc_setting tables, and backdoor admin users added to oc_user.
Common infection vectors: outdated OpenCart core (versions 2.x and earlier have many known CVEs), vulnerable third-party extensions from the OpenCart Marketplace, weak admin passwords, and compromised admin sessions via XSS. OpenCart 4.x has improved security but older versions running in production are high-risk.
Payment-related infections on OpenCart require urgent response — customer card data exposure has PCI DSS implications and can result in processor account suspension. We prioritize OpenCart skimmer cases for fastest turnaround.
Yes — we clean OpenCart 1.5.x, 2.x, 3.x, and 4.x regularly. Older versions receive no security patches so re-infection is likely without a core upgrade. We'll advise on upgrade paths after cleanup.
Top causes in our experience: (1) outdated OpenCart core with unpatched CVEs, (2) vulnerable marketplace extensions (especially free/old ones), (3) admin password reuse from breached third-party sites, (4) shared hosting cross-contamination from other compromised accounts, and (5) file upload vulnerabilities in custom extensions.
No. We preserve all legitimate extension functionality. If an extension is identified as the infection vector, we'll recommend updating or removing it — but only after confirming with you first. Your storefront layout, products, and features remain intact.
The longer malware stays, the harder recovery becomes.
