security - Why do I get these 404-Errors? -

-

i have website , check 404 errors quite often. of them, have quite explanation why them. appear quite often, although sure have never posted link this.

here list of strange 404 errors:

  • js/swiff.callbacks
  • //phpscheduleit/ or //sched/ or //scheduler/
  • /%b0z2%b5%b5a
  • js/+this.options.encoding:
  • js/).match(/\d+/g);return{version:parseint(a[0]||0+
  • js/application/json
  • js/text/xml
  • js/;this.headers.set(

i jused mootools javascript part, use google closure. hacking attempt? how attempt successfull?

should change because of this?

  • //phpscheduleit/ checking software has vulnerability.

  • /%b0z2%b5%b5a name 1 might use install malicious script keep obscure, since google search doesn't turn it's not standard name.
    (it might testing unicode decoding vulnerability, make more sense check particular vulnerable url involving %c0%af directly.)

  • js/;this.headers.set( , bits of javascript code web crawler might pick out possible urls. these string appear on website? not malicous, don't think there's legitimate reason either.

delphi - TJvHidDeviceController "DevicePath" always showing "\" -

i'm using tjvhiddevicecontroller class retrive hid device information. have plugged 2 hid devices, i'm trying ge "devicepath" of sp_device_interface_detail_data_a structure getting device path '\'. ican't open createfile function. please me solve issue. os win7. all. this guessing! the 1 thing can think of is: tjvhiddevicecontroller calls windows api call without using or w suffix. structure used sp_device_interface_detail_data_a, ansi version. now, if use delphi 2009 or higher, routine expect sp_device_interface_detail_data_w. size same looks ok. strings stored usc2 encoded (widechars) instead of ansi encoded -> after every ansi character there null byte. tjvhiddevicecontroller converts character array pascal string using function strpas , hence, see first character. check: set breakpoint after function call fills structure , use cpu window view content memory dump. if see ansi characters every other byte , null bytes in between, ca...
