weird malware

Russell Standish-2
One for the technorati:

For the past few months I've been seeing the following message appear
in my logs fairly frequently:

Jul 29 08:45:54 SamsungBlue postfix/smtpd[28632]: warning: Illegal address syntax from localhost[::1] in MAIL command: <SRS0=KqpXd=PB=ninus.ocn.ne.jp="toki214."@hpcoders.com.au>
Jul 29 08:45:54 SamsungBlue postfix/smtpd[28632]: warning: Illegal address syntax from localhost[::1] in MAIL command: <SRS0=kc6Up=RN=globe.ocn.ne.jp="bello."@hpcoders.com.au>

What is is saying is that something on my localhost (a laptop) is
attempting to send email to an invalid email address, the rather
bizarre globe.ocn.ne.jp="bello."@hpcoders.com.au

I'm guessing this is some sort of attempted mail relay, but I can't
see a rogue process on the system, and the SMTP port is blocked
externally, so its not coming from outside AFICT. Also, cannot see any
suspicious files hanging around in the postfix staging directory
/var/spool/postfix.

The problem persists through booting.

Has anyone seen anything like this before? Nothing turns up on Google.

Cheers

If you search on ninus.ocn.ne.jp, you get lots of spam warnings.  If coerced, I'd guess that you have a program on your machine or in your network that's trying to send out those spam emails.  Perhaps you're part of a botnet?

Frankly I can't wait until our systems all are as fluxed with
symbiotic-ware (what is the benign form of malware) as our own personal
biomes...   maybe we are already on our way down that road?

Does anyone track Stephanie Forrest's computer immune systems?

I'm betting  we have some evolutionary biologists here as well?

Re: weird malware

For the analogy to work, we'd have to use corewars or tierra or somesuch.  The ben-ware, in competing for the available resources, prevent the mal-ware population from exploding.  And we'd have some who had to take regular ben-ware supplements in order to mitigate irritable-output-syndrome and cpu-overgrowth-syndrome.

Personally, I use the analog of frequent, broad-spectrum, antibiotic treatments ... on my phone, at least.  Nothing beats a ROM wipe every week or two to keep your system clean!

That's what bothers me. But I can't seem to find anything about
it.

BTW - this is an openSUSE linux system.

Re: weird malware

Gillian Densmore
Russ,  if it's a browser thing Chrome has a known issue where even on linux extensions (try to) hijack put in malware etc. Quite a few threads about this issue. I don't know what kind of malware and addware gets to linux


Did you  forums to see if it's (relatively)normal, or how your log files get formated etc?

This may help:
http://security.stackexchange.com/questions/11558/how-can-i-find-the-process-that-is-trying-to-use-smtp-to-send-email

The postfix option debug_peer_level may help, though the man page says it's for remote clients.

Re: weird malware

Russell Standish-2
Mystery solved!

It was all a bit more innocuous than it first appeared. There were two
messages stuck in the inbox of my POP server, which because they had
malformed return address could not be downloaded nor deleted from the
pop server, so there they stayed, unread by anyone. Postfix was
writing a message to the log complaining about the malformed address.

I was able to web mail into the pop server directly, and after a bit
of fiddling with the unfamiliar interface, managed to delete them

They were just the usual run-of-the-mill Nigerian-style scam letters,
nothing to be too worried about.

Cheers
