| Scenario | Description | Likelihood | Impact | |----------|-------------|------------|--------| | – an attacker hijacks old-mobile.bet9ja.com and points it to a malicious server. | Users who click on an old bookmark or a phishing email could be served a fake login page collecting credentials. | Low–Medium (Bet9ja likely monitors DNS changes, but no DNSSEC). | High (credential theft, brand damage). | | Re‑activation of Legacy ASPX Pages – old code containing insecure components (e.g., outdated .NET libraries, hard‑coded credentials) is unintentionally re‑enabled. | Could lead to server‑side injection or information disclosure. | Low (no active pages). | Medium–High (if triggered). | | Search Engine Indexing of 404 Page – despite robots.txt, some crawlers may index the 404 page, creating a “dead link” that could be repurposed for SEO spam. | Minor SEO impact; could be used for link farms. | Low | Low. | | Social‑Engineering Use – attackers reference the “old‑mobile” URL in emails to convince victims they are using a “legacy” version of the service. | Phishing attempts that redirect to a malicious site. | Medium | Medium–High (depends on user awareness). | | Supply‑Chain Attack – attacker compromises a third‑party script that is still loaded on the redirect page (e.g., an ad network). | Could inject malicious JS into users who are redirected. | Low | Medium. |
