I got numerous different strange entries in my log today, for the first time.
ALL of them have the same DNS # 200.162.210.*** which traces back to Brazil.

Here are some samples from my Access_log.
Some were repeated 3 to 10 times.

GET /awstats/awstats.pl?configdir=¦echo%20;echo%20;id;
echo%20;echo¦ 562

PUT /tosh.txt 405 300 Microsoft Data Access
Internet Publishing Provider

WGET /_vti_bin/_vti_aut/author.exe 403 301 MSFrontPage/4.0

PUT /default.htm - Microsoft Data Access...

/awstats/awstats.pl?configdir=¦echo%20;echo%20__comeco__;
ls%20/var/www/;echo%20__fim__;echo%20¦ 592 -

All had identical Brazilian DNS #s.

Does anyone know what this is all about?
Have others seen same/similar entries? - Larry

Checking your server for common vulnerabilities. This is usually the first step for a distributed denial of service (DDOS) attack. Second step - if first one would have been successful - would have been to install a backdoor on your system which would then be used in the actual attack.

Thanks for a fast informative response PMK!

I did a G search for some salient words from the first entry (see above).

There was a lot about AWSTATS (which I don't know anything about)
I use Weblog Expert (lite freebie version) to analyze my logs offline. Nothing server side.
I don't know if my host ISP has AWstats or not.

Given the entries I copied above, does it look like their attempts were all failures?
Many but not all of these also showed up in my Error_log file.

May I presume that somebody was trying to use my site to launch a DOS attack on
somebody else, by co-opting my site?

Thanks much for the info. -Larry

The initial scans always test for a whole lot of vulnerabilities (most of them actually would involve a Microsoft IIS for attack). Make sure you run none of the tools checked for, or be current with patches, hotfixes and security advisories.

No reason to freak out though: these guys know NOTHING special about you. Those attacks are fired off to whole ranges of IP addresses to get the few back which are actually vulnerable. They are not after you personally :-)

Hello again:

I never thought it was personal, I figured it was a random thing.

My host ISP uses Apache instead of MS (if that's what you refer to.)

Does it look like the hack attempt failed to you? - Larry

Yes.
