So after having a laptop stolen, and finding really no help to recover it, I had to come up with an idea of my own, or maybe it exists, and I don't know. I want to exploit my own laptop by soldering a USB to the motherboard. This USB, once the computer is turned on and logged into, and detects a network, will do one, or all of three things: 1) Will drop a specific remote access file matching one that is pre-saved in a cloud server, allowing the original owner to remotely access their stolen computer. This file will be dropped every single time on startup, and if the file already exists, will write over the existing one, instead of dropping a new one. 2) Email the owner the IP address of the computer when internet is detected. 3) Email the owner GPS coordinates if available. This would be extremely discreet, and, except the motherboard in which it's soldered to, even if the hard drive was swapped out, or the BIOS or OS was wiped and reinstalled, the drive itself would be present, and persistent, allowing the device to be recovered, remotely wiped, etc. at any given time. An added Idea I was given, was to have this soldered USB contain personal information, and proof of purchase, so the rightful owner can't be contested. Would anyone want to help make this possible? I feel I'm in the right place for this, and I also feel that this would be a product that a LOT of people would really want.

Hello hak5! My name is Danny and im 20 years old. I come from Denmark and at this point I'm writing my final project. My subject is "DDoS" - "How can the British authorities tackle DDoS-attacks" Therefor I have to explain how a DDoS attack actually works. Also I have to involve technical, legal and ethical issues that may arise in connection with DDoS-attacks. I hope you can help me with some of these questions. Appreciated. Regards from Kappa!

/etc/sysctl.conf ##############################################################3 # Functions previously found in netbase # # Uncomment the next two lines to enable Spoof protection (reverse-path filter) # Turn on Source Address Verification in all interfaces to # prevent some spoofing attacks #net.ipv4.conf.default.rp_filter=1 #net.ipv4.conf.all.rp_filter=1 This is in the backtrack "/etc/sysctl.conf" So why this option give to us? what is the reverse-path filter? Are you think This option is most important to hide my ID? Help me...
