Ever need a few extra ports for your network and didn’t want to spend more then a few dollars? Well dw5304 did, so he found a bunch of shit laying around his crib, made a little trip to radio shack and a few hours later he gives us the DIY 3 port powerless hub 😀 He was even nice enough to provide us with a easy follow along tut “complete with a list of tools/materials needed”, and some pics. Heres a few pics to start off with:
Download the tutorial HERE and make your own!! More pics inside. Many thanxs to dw5304 for all his hard work, dc414 wouldn’t be the same with out ya 😛
PHP Shadow obsfiacates a php script for you making it harder to detect on a system. One possible use would be to hide a php shell from IDS/IPS and other systems as well. So how does it work? Well you start with some php code like so:
function go()
{
$txt="hello world";
echo $txt;
}
go();
Then you submit it to PHP Shadow and you should get this back:
< ?
eval(str_rot13(base64_decode('c2hhcGd2YmEgazM0cTFzOTFzbzJyNTE0bzg1NzZzbm8xbjc1bjg5bjZvKCl7JGtwNzgyNHMzcTRxNXM3bzJzMjJxMDM0NzU4cDFyOTQ1ND0idXJ5eWIgamJleXEiO3JwdWIgJGtwNzgyNHMzcTRxNXM3bzJzMjJxMDM0NzU4cDFyOTQ1NDt9azM0cTFzOTFzbzJyNTE0bzg1NzZzbm8xbjc1bjg5bjZvKCk7IHJwdWIgIjxwcmFncmU+PG92dD5HdXZmIGZwZXZjZyBqbmYgcmFwYnFycSBvbCA8biB1ZXJzPVwidWdnY2Y6Ly9xcDQxNC5iZXRcIj5xcDQxNDwvbj5mIENVQyBGdW5xYmo8L292dD48L3ByYWdyZT4iOw==')));

Now paste that code into a blank php file and it will run as normal. So we can see that PHP Shadow base64 encodes and rot13s your code and adds another layer of protection that cant be seen until you decode it. So here is what our code looks like after we rot13 and base64 decode it:
function x34d1f91fb2e514b8576fab1a75a89a6b(){$xc7824f3d4d5f7b2f22d034758c1e9454="hello world";echo $xc7824f3d4d5f7b2f22d034758c1e9454;}x34d1f91fb2e514b8576fab1a75a89a6b(); echo "< center >< big >This script was encoded by < a href=\"https://new.dc414.org\" >dc414< /a >s PHP Shadow< /big >< /center >";
We see that all vars and functions are MD5 hashed to make it harder to follow and see whats going on. The code in italics is added by PHP Shadow to help spread the word 🙂 Thats all i got, enjoy.
I got a sweet arduino for my bday and it kind of just sat around till i got a few things together to start work on my first project. Well i finally got off my ass, got all the shit i needed and got to work! I am about half way done and i thought i would share my progress so far. heres a little video of my toy in action and i go over the operation and components.
Here is a better view of how its put together:
And here is my uber 1337 code 😛
#include < IRremote.h >
int IRRECV = 11;
int READYLED = 9;
int PLAYBUTTON = 5;
int IRLED = 3;
int RESETBUTTON = 7;
int PLAYLED = 2;
decode_results results;
IRrecv irrecv(IRRECV);
IRsend irsend;
void setup()
{
Serial.begin(9600);
irrecv.enableIRIn();
pinMode(READYLED, OUTPUT);
pinMode(PLAYBUTTON, INPUT);
pinMode(RESETBUTTON, INPUT);
pinMode(PLAYLED, OUTPUT);
}
int codeType = -1;
unsigned int rawCodes[RAWBUF];
int codeLen;
void rec(decode_results *results)
{
int count = results->rawlen;
codeLen = results->rawlen - 1;
for (int i = 1; i <= codeLen; i++) {
if (i % 2) {
rawCodes[i - 1] = results->rawbuf[i]*USECPERTICK - MARK_EXCESS;
Serial.print(" m");
}
else {
rawCodes[i - 1] = results->rawbuf[i]*USECPERTICK + MARK_EXCESS;
Serial.print(" s");
}
Serial.print(rawCodes[i - 1], DEC);
}
Serial.println("");
digitalWrite(READYLED, HIGH);
}
