Spam Is Way Down Here…

I was getting 10 spams for every “legitmate” comment recently so I did some digging and found a domain from which most of the spam was coming. A little firewalling took the lot of them out.

DROP all — anywhere
DROP all — anywhere

Now the spam bin is not filling up. I can page through it quickly to get the odd verbose/linky comment to retrieve. Too bad about the rest of the Chinese, however.

  1. There was an interesting research published by a bot-net-creator. He found ~100K routers totally insecure on the web running GNU/Linux (no passwords or weak/obvious/default passwords). He put them to work nmapping the Internet. He planted nmap software on many routers within a day and in several days found about a billion IP addresses in use. Unfortunately he did not report the prevalence of GNU/Linux… He did meet other bots in the process. 😯

    Other goodies he found, a gazillion networked printers on the web with no security.

    That project demonstrates the awesome power of GNU/Linux and how it can be abused. Of course, he could have done the work with that other OS if it were used in routers but…

    Ted, ignores the facts and provides a link whereby insinuating that Android botnets are responsible for worldwide spam. In in fact, infected M$ Windows computers are the true culprit.

    In reality,

    Creating malware for Android, really wouldn’t be any more challenging than creating malware for a PC.

    “I wouldn’t think it would be hugely different if the purpose is to disseminate spam or launch a DoS attack,” Charles King, principal analyst at Pund-It, told LinuxInsider. “The main thing would be to keep the malicious code lightweight enough that it wouldn’t impact the system too severely — and thus alert the user that something hinky is going on.”

    Despite this fact, Android isn’t really any more susceptible than any other OS at this point, King added.

    “Earlier on, Google came in for numerous complaints about the company not thoroughly policing apps in the Android Market, but the company seems to have cleaned up its act,” he noted. “From what I’ve read, the assumption is that the botnet is being disseminated by people who are downloading hacked or cracked apps to avoid user fees.

    So long as you stay withing Google play market, you are safe.

    Further study, shows that 4/5th’s of spam now emanates from computers contaminated with Trojan horse infections.Trojans and worms with backdoor components, have turned infected Windows PCs into drones in vast networks of compromised zombie PCs.

    Point worth mentioning, trojan malware with an .exe extension, does not work on Linux.

    “The culprit behind the spam phenomena is, care to guess?

    Window computers running malware!! Imagine that…”

    It’s been ten years and the problem will never go away. The culprit behind the spam phenomena is, care to guess?

    Window computers running malware!! Imagine that…
