  • Upstream proxy configuration only passes URI and not domain/host

    Hi, I have spent some time trying to configure an upstream squid proxy server in order to have a known source IP address for testing engagements, without relying on a VPN (unfortunately in my specific circumstances a VPN is not usable).

  • Burp Mobile Assistant - empty Source repo on Cydia

    Hi Burp team, I am very grateful for the new Mobile Assistant feature. I downloaded it today (with Free Edition v1.7.21). I can get my jailbroken, ios 9.3.3 device to add my Cydia source: http://localhost:8080 but the package is always empty, after successfully adding the source. I am updated on Cydia Substrate (version 0.9.6301). Any ideas?
