Intruder 202.176.209.3, of SingTel, Singapore, Uses DNS To Map LAN

Bear in mind, when reading this, that there is absolutely no other traffic on this LAN. The LAN is effectively in honeypot mode.

202.176.209.3 seems to be using DNS to map the network. I've seen this before where the attacker floods the outer router with unsolicited DNS replies. When an inner Router realizes it has no ability to make DNS requests via DNS relay, it is referred by the next router on the outbound side to it's DNS providers...and the hacker is outside watching.

Sender Policy Framework: Protect Your Domain Reputation From SPAM

Sender Policy Framework
One of the more correct responses to hackers (computer people) devaluating your assigned IP's, your domain names and your email addresses by sending SPAM in your name, is called Sender Policy Framework (RFC 4408).<< MORE >>

Free IOS Script: Attempting To Use Cisco 861 To Mitigate Hacking.

While attempting to compete in the job market, I found I was getting killed on the Internet.  At its peak, the intrusions attempts amounted to about 82 unique IP's in a little more than 60 minutes, which disregards the possibility there were also other non-IP protocols and disregards the multiplicity of attempts at attacking concurrently.  Obviously, when I realized I couldn't keep pace with the hackers, I pulled the plug.

Hacking: Updated Script To Remove Hidden Shares.

The Sources Of Hacking.



It seems I've experienced more hacking in the last several months than in all my time on the Internet before.  Consequently, I've spent a more time than I have to spare writing firewalls and scripts to protect my computers from intrusion.

Vulnerabilities in Firefox, Thunderbird and SeaMonkey.

My previous post, with regard to a script to protect your hard drives from exploitation of the Microsofts default "administrative" (hidden) shares, was in no way intended to suggest that would completely protect your system, only that it might help close up one specific vulnerability.

So apparently, some hacker (or hackers) thought they'd teach me a hard lesson in exploits and loose sourch-end routing. All you need is a computer, nmap, metaspoit, the ...

Remove Windows' Administrative (Hidden) Shares.

What this means to you, as a user, is that if you check to see if C: is shared, in the Graphical User Interface, it will tell you that it is not, hence the "hidden" nature of these shares. The problem is that every technician, administrator, hacker, enthusiast, etc. knows about these "hidden" shares. So where's the "hidden" part really? It's only hidden to the unsuspecting user who thinks that he or she is protected by their software firewall and antivirus, and that Windows' resources are protected by their password, assuming they actually implemented any passwords. Nothing could be further from the truth (there will be a lot more on this later). One of the things I can help the average home user out with, with minimal effort, is how they can get their Windows 7 Home Edition to not share their hard drives' contents with the entire world. << MORE >>

The SPAM Scam: Resume' Blocked By Barracuda.


I wanted to share this with people who are blasting their resume's out to potential employers because they may not realize that they're setting themselves up to have their email address flagged as a SPAM.

A former recruiter, who is also seeking computer certifications at a school I'm attending, recommended that, in these times of high unemployment, I should be sending my resume' to businesses other than just those who are actively advertising positions available. After about ...
