No. You should be alright as long as you have some antivirus running.  (most have)

Our internet provider has many systems in place to protect us & as a result we seem to have little or no trouble. It was very bad a few years ago & they were loosing customers left/right & centre. Needless to say when it started to hurt their bottom line they made a large effort to stop most of it & it certainly works, Mick B.

It is a pity that the Internet Providers are not doing much more about these pain in the
 posterior pests, there must be a lots more that they could do to block them.

Agree fully, O0 O0 even here in Oz an ISP will only take action if and when you complain. <:( <:( It then becomes clear they, the Provider, was aware but did nothing until complaints are received.
Bottom line, they seem to only do what they have too, as all else costs them time and money >>:-( >>:-( <*< <*<

And my isp is protecting me from being tempted to break the law by locking out those naughty(cle) privateers. So it can be done quite easily but only at THEIR discretion. It seriously affects the profits by banning spam etc.

Just to shed a bit of light on this:

My wife and I own HyperGold.com, a web development and hosting company in California. All day,every day and every night, our server is under attack by hackers. It has nothing to do with vandalism, as some people think (although Internet vandals do exist, and do target specific websites for bragging rights). Aside from those few, highly-publicized ANONYMOUS-style hacks, where the hackers are trying to make a point of some sort (as if the rest of us care about their opinions), these non-stop hacking attacks have one purpose: to take command of our server. Why? To use it to make money. This is true even of the Chinese state-sponsored hackers.

What is the easiest path into a hosting server? Through a public forum or other variety of membership-based, open source website (JOOMLA, Drupal, WordPress, etc.). This is because (a) the code that these sites are built on is open source, meaning the hackers can reverse-engineer it to find security flaws, and (b) in order to have a membership-based website, the restrictions normally in place for a static, private site are necessarily looser. Without those looser restrictions, members would not be able to log in, post, edit their profiles, forget their passwords and have new ones emailed to them, etc.

The only way to guard against these !*^R&^*&*hole hackers is to have the website maintenance folks (often a single individual such as Martin) stay constantly on guard, always on the lookout for new versions of hacker crap prybars trying to break in. The hackers are always one step ahead of the open source development community, because they find these vulnerabilities and exploit them, and then it takes a while for the administrators to find out that it's been going on in a new and exciting manner than last time. Then the development community scrambles to close those doors, releases a security update, and then the poor administrators (who just want to, say, build model boats) have to drop what they're doing, clean the glue off their hands, and apply the updates.

Meanwhile, the hackers have been using the server as a conduit for porn, spam and gods know what else, and guess what? The website - or even the entire server - gets blacklisted across the Internet, and that means that email sent to, from and through that server or website stop getting delivered. At the same time, the website administrator gets a warning from his/her ISP to fix the problem immediately, or get shut down. This warning comes, often, from the ISP's ISP (everybody has one.), and it's a chain reaction, all he way up to Mount Olympus, where the Internet gods bowl with our heads.

Finally, the bonus question: What's the easiest way for hackers to gain entry to a server through a website like Model Boat Mayhem? [drum roll, please]

Give up?

The answer to the question is: by hacking the members' computers. How? By relying on the fact that we're a bunch of lazy "xxxxx" who just want to play with toy boats, and who can't be bothered with keeping our anti-virus and anti-malware software up-to-date - that, and the fact that we get taken in by offers too good to be true, click on links to websites we've never heard of, and can't resist opening attachments - especially when it's something wrapped in patriotism, our particular religious dogma, political causes we espouse, hobby-related offers and deals, and so on. Some of those wonderful opportunities are pathways into your operating system, where you have all of that nice information on your accounts, usernames, passwords, and address books.

If this sounds like you, take some steps to help Martin out (and yourselves, too) by following these simple steps:
  • Use a program like Norton 360 to scan your computer regularly for viruses. Keep the software up-to-date by checking it regularly for missed updates.
  • Use a program like Malwarebytes to scan your computer nightly for malware, which are small programs that install themselves on your computer, and may do nothing more than steal your address book, or record your keystrokes, so that every time you log on to a website like this one, it sends your username and password to somebody in the Ukraine. Keep the software up-to-date by checking it regularly for missed updates.
  • Never click on a link to a website you've never heard of, even if the link is in an email from a friend. Instead, copy the link, and Google it by pasting the address into the Google search window.
  • Never open attachments that come with an email, even if it's from a friend, unless you know absolutely 100% for sure that it's legitimate, and virus and malware-free.
  • Never respond to spam, even if you think you have something devastatingly witty to say. He will simply add your email to his "confirmed" list, and sell it.
  • Never, ever, "pass along" emails that urge you to pass them along to all of your friends and family. Chances are that you are passing along viruses and malware to your friends and family.
  • Never, ever, click on a link to update your information on any financially-related website. No legitimate company will send out such an email, so you can be certain that it's not your bank, eBay, Amazon, or Model Boat Mayhem asking you to do it - even if it looks like it is.
  • Finally: No friend or family member is going to email you with a request for money, because he/she has been robbed and is stuck in a train station in Istanbul or Athens. Friends or family members who get robbed and are stuck somewhere are going to call you, charges reversed, because they have no money, no computer, no smart phone, etc.
Sorry for the epic length of this post, but I hope it helps someone.

I'm glad you folks appreciate the effort. It's a fairly arcane subject, but these crooks affect all of us.

Here's a true story that illustrates just how difficult it is for ISPs and web hosting companies to prevent this sort of damage...

One of our new clients has a WordPress site. Now, WordPress is a very popular, open source (free) canned website maker: just press a button, fill in a few fields on a form, pick a theme, and presto! Instant website. I have nothing against WordPress, but I do have a problem with so-called web developers who will make one of these for an unsuspecting small business owner, charge what is ridiculously lower than any legitimate web developer would need to charge for a business website, take the money, and disappear. The business owner is OK, because he thought he wanted to have a website he could change day-to-day himself, and that's just what he got.

Only problem is that hackers have targeted WordPress in a big way, and the business owner has no idea that his website requires constant updates, because his "web guy" is long gone. So, his little website becomes increasingly vulnerable to invasion, but he's blissfully unaware, working on running his business and living a normal life.

Why and how would some hacker in China or Brazil or Nigeria bother to hack such a tiny little website with an equally tiny amount of traffic? How would he even find it? But I digress. Back to my story...

One day, as I was writing up a contract for a project for this new client, I browsed to her website's home page to get her mailing address and contact info, and found this warning from Google:



Being the curious sort, I investigated. What had happened was that our new client's WordPress site was woefully out of date - at least 3 security updates behind - and hackers had exploited a known security vulnerability. Once they gained access to the hosting account, they created hidden directories and uploaded huge amounts of porn, and began to use the accounts Sendmail function to launch hundreds of thousands of spam emails, each with links to what appeared to be legitimate commercial websites, but were in fact Phishing sites (sites designed to gain personal information for the purpose of identity theft). Also, some of the links on some of the pages built on our client's site redirected visitors to sites containing viruses intended to take over the users' computers, and it was these redirects to known Phishing sites that tipped off Google's web crawler. (A web crawler is a program that wanders the Internet, recording (indexing) all of the pages on websites across the web. That's how Google is able to find sites that match your search words.)

At any rate - and this is the most important part of the story - until Google's web crawler discovered this problem and intervened, no one knew anything was amiss with our client's site. These insidious a-holes don't touch the web pages on the accounts they take over, so to everyone visiting, it all seemed OK - maybe a bit slow - but OK.

Back to the question I asked earlier:
 
Why/how would somebody find and take over such a tiny little website with almost no traffic?

The answer is that "somebody" didn't. Just as the search engines send out automated web crawlers for legitimate purposes, hackers send out web crawlers of their own that look for vulnerabilities in commonly used code that have been identified and successfully exploited, and when these "bots" discover a site that has not been updated, they take over and automatically set up all of these directories and malicious programs. No human intervention required. In this way, one hacker can take over hundreds of thousands of servers - at least temporarily - without anyone knowing.

Food for thought, hey? It takes constant vigilance and timely maintenance to keep all of this under control.

That was very enlightening Rob. Can hosting companies recognise unusual behaviours from a site like Mayhem?

Just a quick home question; Do tablets need protection and if they do then what? My wife has one and my son uses it.

Hi Dave,

You posed two questions. I'll try to answer both.

First question: Can hosting companies recognise unusual behaviours from a site like Mayhem?

Answer: Yes, but it depends on the definition of "unusual." Martin can confirm this, but there is always "unusual behavior" on a site like this one. "Bots", short for 'robots', are increasingly adept at mimicking human beings. There is going to come a day in the not-to-distant future when it will become impossible to distinguish  between an AI (artificial intelligence) - based program and a human being - at least on the Internet. It's already happening in tech support and customer service, where you might decide to engage in "live chat" on a site that offers warranty support for an appliance you purchased. You think you're chatting with a human being named "John," when in fact, you are engaging with a computer program that is programmed to look for key words and key phrases in your questions, and reply with sentences that incorporate your key words and phrases. As in, "Dave, I'm sorry you're having problems with your [insert appliance make and model]. I'm going to ask some questions that will help me understand your specific problem, and - maybe - suggest some solutions. OK?"

Keep in mind that hosting companies typically have thousands - or even millions - of clients, and they tend to automatically scan for anomalies. For example, let's say www.modelboatmayhem.co.uk typically sends out x number of emails per day. But suddenly, the site is sending out three times or ten times the average number of emails per day. That would raise a flag, and a technician would investigate. Same with a scan that ISPs regularly perform that does the same thing that hacker bots do: Look for code that has been exploited and reported, and if it finds it, warn the customer to either fix it or have the ISP disable it.

Your second question: Do tablets need protection, and if they do then what?

Answer: A tablet is a computer. If it's connected to the Internet, it has the same vulnerabilities as a desktop computer. You still need to follow the same common sense maintenance, and proactive safeguards as anyone else. The simplest way to look at it is that if you open the window in your house to get some air, and you go to bed, that window is still open. Who is going to guard it from home invaders while you sleep?

Dave


It all depends on the tablet


Ipad
No.  Due to the way the ipad operating system and the App store are locked down it is extremely unlikely that you could pick up a virus or malware.... I'm not saying it's impossible but it highly unlikely.  (there has been one reported incident from an app on the russian app store)


Android
Yes, there have been problems with viruses and malware, so some sort of protection is reccomended.  I don't know enough about the android OS to make any recommendations


Windows based
Absolutely, the same applies for a windows based tablet as does a windows desktop PC or Laptop

  • 'Never click on a link to a website you've never heard of, even if the link is in an email from a friend. Instead, copy the link, and Google it by pasting the address into the Google search window.
Although I'd never describe myself as 'Tech-Savvy', in the 15 or so years I've been using the www's I've only once had a detected virus - it was in the very early days when I didn't understand the need for updating my security software (did I mention my lack of tech-savvy ness!!) I thought it all happened through some form of background magic. Needless to say, the PC slowed to ridiculous proportions rendering it utterly useless. Took some more advice and installed 'Kapersky', which had been supplied with one of SWMBO open university courses. Once installed & running I was totally horrified at what it found and subsequently cleaned up. My all singing all dancing pentium 4 system was back.  The initial 'attack' was found to have come from an email attachment (a friend had sent an email with attachments from his work computer & it was subsequently discovered that their IT guy was a low functioning alcoholic who didn't have a clue what he was doing).

Getting to the point, I think my attitude to web security is now slightly over the top but hey, I've never had a security breach that has caused untold damage.  I highly recommend Rob's advice above, especially that in quotes at the beginning of this post.

Please, please take note and keep your security up to date. I've always found the likes of Norton etc, while doing an excellent job are somewhat resource hungry and are invariably the culprits when I notice a slow down. On each occasion I've eventually managed to remove the preloaded anti virus software & have usually replaced it with Avast - I'm nothing to do with them, just a satisfied user of their basic (& free) web security system.

An earlier post alluded to the idea of not needing anti-virus software on apple tablets because of its iOS. As far as I know both the iMac & MacBooks do now need a-v software but the jury's definitely out on whether or not things like iPads need them - I'd be grateful for the current thinking from those in the know.

Final point (promise !!), the reason apps for apple are safe is that nothing goes on the store without being checked by apple. GooglePlay on the other hand allows any 'app for android' to appear, so yes, following current convention Android really does need protection whereas Apple doesn't but surely this only applies in the app world. Don't we also use our iPads to browse the web? Can we really be sure that any website we visit is totally clean? Therefore does an iPad need a-v software for web browsing? I'd certainly welcome some expert advice on that one.

In the meantime, I firmly believe that we all owe a huge debt of gratitude to Martin for all that he does quietly in the background and keeping MBH available to us without that many interruptions..

There does appear to be a good selection of security options for apple products, which suggests that the policy of "one shop only" does have ways around it in the real world that industrious black hats are eager to exploit.

Not long ago, all apple products were thought to be malware proof, mostly because they were rare birds and thus a small target.  Bearing in mind the demographic of apple users, like nice looking items, don't want to know what goes on inside, are prepared to pay extra for not thinking and thus have something worth stealing, its only a matter of time for the rest.

Apple "i products" simply haven't been heavily targeted by hackers - yet.

Just to be clear: any technology made by human beings can be "unmade" by other human beings, and any security system - whether it's a firewall or a stone wall - can be breached by a persistent siege engine.
