Keeping Track of the Bad Guys
When I took some Russian classes at Purdue, I was one of the few non-ROTC students in the room. In that same spirit of "know your adversary"....
There are sites where "carding" or selling stolen credit card information goes on openly. Also counterfeit currency, stolen smart phones, etc. OmertaHack is one example.
Hackers in the Classic Sense of the Term
Magazines and web sites catering to the community of bad guys, or at least security researchers plus some wannabe bad guys and posers, include 2600 and Phrack.
Hacker hangouts and groups providing information exchange and tools include the Chaos Computer Club Berlin.
There are lots and lots of ready-to-compile programs for testing your systems with the same weapons the hackers will use. Start looking at Packet Storm Security and AntiOnline
Stack smashing refers to a specific form of attack on poorly coded memory management code. There was a great paper on how to exploit poor coding via buffer overflow and related attacks in Phrack volume 49, "Smashing The Stack For Fun And Profit". Get the original paper at insecure.org Packet Storm.
There's a nice follow-up paper on writing advanced buffer overflow exploits.
Spamming and Stolen Accounts
Criminal organizations openly sell access to hacked systems and spamming software. I received the following email. "WebMails" will mean stolen webmail accounts, "Shells" mean access to hacked Linux/UNIX systems, "RDP" mean access to hacked Windows systems.

Let's look at the headers to see where this came from:

They're not trying to hide! This seems to have come right out of mail.visko-td.ru, and the IP block 220.127.116.11/21 is allocated to InterTelecom ISP in Ryazan, Russia.
Software keys, serial numbers, patches
There are large searchable databases of the keys and other bits needed to unlock "warez", pirated copies of Cisco certification exams, etc., at Crack Spider and CrackWay.
This category includes license key generators for embedded engine control systems for large trucks, construction equipment, and generator sets. The illicit license key generators are sold online by operations like EPC Software.
You can see in the below that the seller uses Turkish, which isn't the dominant language at John Deere headquarters. "12 Mayıs 2011 Perşembe" means "Thursday, 12 May 2011".
Of course, many of these are scams. They either take your money and give you nothing, or they've sold you a link to download something that doesn't do what it promises, or something that's infested with malware. The epcsoftware.com operation used to be epcdvd.com, and has also operated as tukkor.com and several other URLs, according to this forum of angry people calling it out as an illegal scam. The second page of that thread lists several other URLs where heavy equipment keygens (and malware masquerading as such) is sold.
Remember that Trojan Horse construction hasn't changed since ancient Greece — make it look innocent, simultaneously doing the expected thing and some bad thing. When someone tries to get the system administrator to run some program, remember Virgil's Aenid, "Timeo Danaos et dona ferentis," or "I am wary of Greeks, even bearing gifts." Some "security scanners" may just be Trojan Horse software.Back to the main Security Page
