BNA Forum and Site Downtime

Postby AUbicycles » Mon Mar 19, 2018 6:39 pm

Thank you for the email and facebook reports.
Unfortunately I was not aware of this earlier and couldn't respond.

It appears that BNA was (again) flooded by unethical bots. Their intention is to scrape the entire site as fast as possible which puts a massive load on the site and beyond preventing access, they also rapidly 'suck' all of the hosting credit so when they finally stop, then this continues to prevent genuine people visiting as the host sees that the entire 'contingent' has been used.

I will try and find out more about this to try and prevent - but thank you for the positive message, support and patience.

+1 to what DD said.

The world didn’t end and the fact that people do this sort of stuff is saddening,but a frustrating part of life.

As usual, many thanks Christopher :-)

What's attracting those bots to this site? What value do they gain?

Stupid bloody search engines...can you identify the bots via IP or name and block them at Server ?

We appreciate your hard work btw.

WW forum has also had problems in logging in. So no idea if it’s the same issue or something else

Sometimes they are scraping the site, then duplicate the site with manipulated content to try and trick genuine search engines.

Sometime there is brute force hacking to try and break in.

Sometimes it is dubious ‘services’ that crawl the site bug do it poorly which affects access and don’t use thd content they gain in any useful way (ie dodgy, unethical or scam).

I have some tools in place to limit the baddies but the bad ones utilise bot nets and attack from many different Ips.

When I consider spam rnails and the non-genuine traffic, it would be fair to say that at least half the traffic on the entire is not genuine.

It's a bloody annoying battle to fight against them. Never ends either. Kudos for trying to keep on top of it all.

Been hit again. Unfortunately I can get log details and have to try and work out how I can get the crucial info on who is flooding BNA.

In short - it has the effect of a DOS - Denial of Service attack although I can't say it it targeted, rather it is more likely simply aggressive (and illegal, unethical etc).

Bruce Schneier had some interesting musings in his latest Cryptogram newsletter. He postulated that machine learning could tip the threat/response balance in cyber security more towards the defence side than it currently is. Not that that helps now...

The CrazyGuyonabike site reported a similar attack a little while back.

Neil who can get a bit paranoid at times immediately blamed a former site member.

Are you aware of any other cycling related sites which have been attacked?

It seems to be a pattern now - has happened again and I think I got it fairly swiftly.

In the meantime I may be able to configure it a bit - but as I am stuck without access to original log files - it is a bit tough. At the moment it appears to be a forum issue - so it is the forum rather than the main site that it being overrun.

As I am travelling - I have limited time but will try and keep an eye on it and at least attempt to get it back online as soon as I can.

Update - I finally found the culprit - a 'service' called Carma who were flooding BNA with their 'ScooperBot'.

They were flooding the site with a massive amount of requests - this put our CPU load to maximum, used all of the CPU credit and knocked the site offline until I could manually replenish the credit. The effect of a DOS attack (Denial of Service) which also lasted longer because all the credit was gone.

Unfortunately, it is not easy to stop but I have taken some measures to try... and hope that they stop it themselves as it is a very destructive bot and is essentially unethical because it floods and requests the same file thousands of times a second. Their website lists some fairly reputable clients such as Emirates, Canon, Nestlé and Mont Blanc so it is unfortunate that with what appears to be an impressive client-list, they need to resort to such unethical activity.

Here is small sample for the techies.

Also, Microsoft Bing is just as bad. While the load is not as heavy, they are permanently crawling the website and the bingbot ignores the rules - these are rules which Microsoft / BingBot confirms on their website - but the delay and even a disallow has no effect and bingbot has a fairly big load - up to 80% of the traffic (load) at times.

Cheers
Christopher

Now knowing the IP address of the main culprit, can you not block the bot using something like .htaccess ? Or are they aggressive enough to get around this ?

Yes - as soon as I found it out I put in the block they can still flood the site. I am tracking surges where up to 80% of all traffic is getting blocked.

A person from Carma did get back and they said they will remove BNA so it just leaves the nasty bingbot.

Correct... I tried and the chat robot said "would you like to speak to a person?" I chose Yes. Then was provided a link to the bing community discussion forum... what a joke.
