The Internet's Bad Neighborhoods 77

An anonymous reader writes "Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the spamming IP addresses — and some ISPs have more than 60% of compromised hosts, mostly in Asia. Phishing Bad Neighborhoods, on the other hand, are mostly in the U.S. Also, there is a silent ticking 'spam' bomb in BRIC countries: if India would have the same Internet penetration rate as the United States while keeping its current ratio of malicious IP addresses, we would observe 200% more spamming IP addresses worldwide. These are just few of the striking results of an extensive study from the University of Twente, in The Netherlands, which scrutinizes the Internet Bad Neighborhoods to develop next-generation algorithms and solutions to better secure networks."

    Anybody who's worked at a datacenter has known this for years and years. And comparing them to bad neighbors is correct... if we didn't consider scope and the medium. It's a lot harder to police something that's not in physical form and is transitional, and A LOT harder when it's in a country you don't have jurisdiction over. Sure you could block these ISPs and in a lot of cases it makes sense, if your website is national, then it can save a lot of pain, but it's not the end all solution to spam.

    • I wasn't aware of the India issue, were you?
      • India was called Eastern Europe a few years back in regards to spam. The locations may change, the concept of a botnet remains the same. Obviously, spammers will find the least regulated, easily available ISP around.

          Tracking sources of spam seems to be the best way to see where growth is happening in internet connectivity. Remember when South Korea was the source of all our spam? For no other reason that there were a lot of very fast internet connections popping up faster than they were being secured.

      • I was. India easily has the potential to quickly transform into the next "Nigeria" once their internet penetration gets large enough.

        Combine millions of people in poverty with easy and less than honest ways to quickly swipe money from some "rich" foreigner?

      Most of us don't work in datacenters.

      I think this could easily become a huge issue. We are lucky that most phishing emails are of a very low standard and it's easy to spot the fakes.

      I'm guessing that these developing countries don't take cyber crime to seriously at the moment, perhaps instead of governments pushing SOPA and and ACTA they could come up with agreements which will encourage BRIC nations to start cracking down on spammers before the problem gets out of hand.

      • And with enough resources they would... that's why the spammers pick them. But the problem is mobile, it moves from country to country, simply blocking IP blocks is a band aid solution.

        • And with enough resources they would...

          China most defiantly has the resources, it just needs to put them in good use, instead of trying to block freedom of speech. Start putting pressure on ISPs that allow their networks to be abused. The spam might move between countries, but I assume the spammers themselves must be located somewhere.

          Follow the money trail and start closing bank accounts.

          • Defiantly...?

            I had the solution for virus/malware/spammers years ago: 6-12 of them each day hanging by their ankles naked in Times Square (or some other central location), on international tv for the duration; crowd can go to town on them from a short distance with verbal & organic 'substance' abuse of choice (just no serious/major physical damage allowed). I think within 6 months the problem would be down to 5-10% of the volumes it is now. :)

            I'm pretty sure that China's government doesn't care about the amount of spam being generated from their networks because the target of the spam is not their citizens, but rather people in other countries.

        • Yeah, they move around as they get blocked/lose their accounts. More than half the spam *I* see nowadays seems to come from Ukraine or Spain. There used to be mostly spam originating from Brazil a while back, and a few years ago it was almost exclusively coming from Bulgaria. But the contents were the usual top 10. Most of the activity in general from Ukraine and Russia is people trying to get into Wordpress sites I run. Fail2ban and plugins take care of them, but I don't get why anyone would want to spend

    Those aren't the phishers you're really worried about. There seem to be about ten "usual suspects" we keep seeing on our phishing reports. The low-end ones are trolling for Habbo Hotel accounts. A few notches up are phony logins for bank accounts (PayPal and HSBC are popular targets. New this week: Swedish tax refunds. And, for some reason, several new phish sites for AOL 9.0 accounts.) We track these, but they're more of a nuisance than a real threat.

    The ones to worry about are better targeted and are of better quality. Those are aimed at corporate login info. Those won't be seen by broad-based phishing detection services because they're only sent to people who might have those logins. So they tend not to be blacklisted.

    Brazil: 196,655,014 people (World Bank)
    Russia: 141,930,000 people
    India: 1,241,491,960 people
    China: 1,344,130,000 people

    that's 2,924,206,974 people total.
    world population: 6,973,738,433 people, so BRIC countries are 41% of the total in population.

    FTFA:

    Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the internet addresses that send spam.

    so I take it "nearly half" is between 40% and 50%, but less than 50%. If it's over 41%, then what we are looking here is some form of distribution of 'nuisance' that is related to the actual population and it probably shows normal distribution.

    Is this really a surprise?

    • by AK Marc ( 707885 )
      Yes, and when "China hacks US companies" we never see how many hacks on that company came from non-China addresses. If 1/100th of the attacks are Chinese in origin, why aren't we invading the US to stop the other 99/100, or wherever they are coming from? It seems to be an irrational nationalistic play, not an evaluation of risk and reasoned response to a threat.

        Hacking attempts have different severity levels associated with them. Putting them all in the same bucket as if they were all equivalent would be disingenuous. Besides, no one rational is saying that we should be invading China over this. Also currently, if a hack is severe enough, and coming from the US, the police/FBI goes after them.

        It seems to be an irrational nationalistic play, not an evaluation of risk and reasoned response to a threat.

        That could be true. I'm not saying that it is, or that it is not. Personally, I just don't know.

        Do you know? How do you know? Is this your field?

          It is my field. I've never been "attacked" with a coordinated intrusion attempt. I've worked on systems that were hacked by script kiddies with no agenda (it was used only for warez, when they compromised a web server). But scans I get, and I've seen port scans referred to by the US government as "attacks" because that helps generate fear and hate in the population, which allows for money and power grabs. And those seem to be distributed more on the level of compromised machines, than concentration in areas where we have "enemies" (real or perceived).

          As such, I would take the official numbers to be lies, until proven otherwise. Why? Because I have enough personal real-world experience in security to validate the implied raw numbers and invalidate the conclusions. That's why they'll never tell us enough to make up our own minds. Someone like me could prove in 5 minutes that all the conclusions are lies. So we only get false generalizations and, for all we know, 99.44% of Chinese attacks are false flag. Much like the claims that "an IP doesn't identify a person" in the copyright cases, the US is asserting that an IP from China is the government or an agent thereof. It could be a private Chinese citizen, or, more likely, someone from Russia or the US that runs a botnet.

        First, it's because China is currently a main economic "enemy" to a lot of western economies when it comes to "jobs" and "quality".

          Yes, if it's a military attack, we might ignore it. If profits are threatened, we must stir the populous into a frenzy. It doesn't even have to be true, the effect of the propaganda campaign will still help secure profits.

          The second reason is that China is hardly trying to disguise that it's a large, government organized and funded group of hackers that is doing this.

          How would China conceal something they aren't involved in? And are they really tracing them back to the Chinese military? I've not seen documentation of that, usually they end up tracking it down to some guy in his home, they assert him to be a military operation, or something like tha

Spamcop seems to become more and more pointless as more and more abuse@ addresses bounce. Furthermore, in my experience, more and more ISPs start using their own forms for reporting... Handling abuse costs time, time = money; it's a whining geek versus a paying customer. And as long as they can get away with it, they prefer the latter (and hence make it very hard for the former to contact them).
