My iPhones and several smart-home devices have almost certainly been compromised. Unexplained behaviour, network slow-downs and repeated password lockouts suggest an active intrusion that I have not been able to stop remotely.

I am conducting an authorised security assessment on a website that currently sits behind Cloudflare. The owner has given me written permission to verify how well the service hides the origin server, and my first objective is simple: locate the true, routable IP address of that server. What I need from you • Discover the origin IP without disrupting production traffic or triggering any Cloudflare security events. • Confirm that browsing directly to the uncovered IP renders the site identically to the public domain (same content, layout, and functionality). • Provide a concise report describing the exact approach—whether you relied on passive DNS enumeration (dig, SecurityTrails, Shodan etc.), historical records, sub-domain leakage, server misconfiguration, or ...

I’m preparing to replace our legacy MPLS links with the SD-WAN service we’ve already contracted and need an on-site engineer in Hyderabad, Telangana to drive the entire cut-over. The environment is small—fewer than 50 routers, switches, firewalls, and edge devices—but the migration still has to be planned and executed with zero-downtime goals. Here’s what I expect: • Audit the current MPLS topology and document every dependency. • Translate existing QoS, security and routing policies into the new SD-WAN orchestrator. • Build and stage configs on the vendor-supplied edge appliances. • Coordinate with our carrier and internal teams to schedule and perform the live switchover. • Validate traffic flow, fail-over behavior, and app...

I need a seasoned PHP security specialist to comb through an existing application, locate and remove every hidden backdoor, then harden the code so it stands up to malicious probing—SQL Injection is my top worry. Once the cleanup is finished, you’ll redeploy the patched build to my live PHP stack and confirm that all features operate normally under real traffic. A successful engagement means: • a brief, private report pinpointing each issue you discovered and how you neutralised it • a fully patched source tree returned to me, ready for version control • the application running stably on my server, with verification that the fixes prevent the SQL Injection vectors you identified Please come prepared with practical exploitation knowledge, the usual security ...
