TR-069 & Security / Swisscom Router
by Nico Schottelius 27 Mar '16

27 Mar '16

Hello Swinog, we've recently audited a small network and found that the customer configured devices were relatively secure configured. However the Swisscom Router/WiFi device (Zylex P-870HN-53b) seems to have the old uPNP exploit with a firmware that is not being updated anymore (upnp was disabled though - so this is hopefully not a big issue). However, when scanning the router from outside, the port 7547 is openly reachable from the internet, which turns out to be TR 069 [0]. My question to the list is, if anyone can comment on the security of TR-069? And if it is a potential or real security problem to have the port open world wide? We have never used TR-069 it so far, but my assumption would be that this port should only be reachable from a Swisscom admin network, however it is open world wide. As far as I can see the communication on port 7547 is plain http with http auth, which doesn't look very safe to me. Does anyone here use TR-069 and if so, what is your the default policy for accessing the port? Thanks a lot for your help and greetings from the last snow!

Swisscom now peering with Netflix
by Fredy Kuenzler 25 Mar '16

25 Mar '16

In case you missed it: Swisscom now peering with Netflix after big shitstorm in social media and general media yesterday and today. http://pastebin.com/sgwD3qfh I suppose the peering policy of Swisscom is now obsolete, as well as their monetizing OTT strategy. It's a good day for real netneutrality, not the crippled version of some larger Swiss operators. -- Fredy Kuenzler --------------------- Fiber7.

Re: [swinog] Reject von hotmail.com -- also Swiss providers do this nonsense
by Charles Buckley 22 Mar '16

22 Mar '16

I have also been having trouble with my Swiss provider (hosttech) making such insane spam rejections. 1. Recently I travelled to Germany, and stayed at a hotel using Deutsche Telekom as broadband provider. Apparently the entire DT DSL pool appears on two blacklists, so Hosttech just ignore them. No error message is returned, just a timeout -- a behavior so typical of Swiss bureaucracy. I got around this by using Google or GMX to send my mails. Hosttech first tried to tell me my settings were wrong (not likely), but finally had to confess that they were the problem. 2. Some time ago, I sent an email message containing the name of a Rumanian colleague in the body. That time I got an error message saying 'This server doesn't like spam.' I took the Rumanian name out, left everything else the same (except the recipient address, as the mail no longer made sense to the original recipient) and the mail went through fine. Concerning the first problem, Hosttech claim they fear getting on blacklists themselves, or that evil scripts might get uploaded to the SMTP server. I've never heard of such a thing, but even if it were true, since they use SMTP-Auth, isn't it enough to insist that the SMTP-Auth credentials are restricted to users who don't send spam, and to block the credentials of those who do? Why make something simple so bureaucratically difficult and obnoxious? To expect a user travelling on business to drop everything in their busy schedule to get IP addresses out of a DSL pool removed from blacklists by contacting a local broadband administration with whom they are not customers strikes me as completely unreasonable.

Registriere bei postmaster.live.com ... (yep, und auch bei google etc, die grossen haben kein lust um spam zu empfangen, so schieben sie das auf der ISPs die gerne mail wollen schicken) Richtige WHOIS, reverse DNS, SPF + DKIM und naturlich funktionierende abuse@ und abuse mail auch richtig behandeln. abuse-c oben ist abuse(a)contabo.de und wann dort sage 50 /24s hin gehen und aus der 50, 1 /24 viel spam geschickt werde und abuse@ das nicht losst, dan werd gleich die andere 50 auch als 'reagiert nicht' markiert, also.. rufe deine ISP an und frage mal nach ob die abuse behandeln...

Reject von hotmail.com
by Klaus Ethgen 20 Mar '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hallo folks, zur Zeit bekomme ich meine Mails an hotmail.com-Adressen mit der Meldung "550 SC-001 (COL004-MC2F18) Unfortunately, messages from 5.9.7.51 weren't +sent. Please contact your Internet service provider since part of their network is on our block list. You can +also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors." abgelehnt. Auch mails an postmaster werden, entgegen jeglichen gültigen Standards mit der selben Meldung quitiert. Die IP 5.9.7.51 ist meine Outgoing-Adresse und ist seit Jahren der valide Mailserver meiner Domains. Ich kann auch ausschließen, daß über die Domain auch nur die geringste Spam oder andere Malware versendet wird. Haben noch andere diese Probleme mit hotmail.com bzw. hat wer eine Kontaktmöglichkeit zu denen? Irgendwie habe ich das Gefühl, das die ihre Server nicht im Griff haben.

Bei den einschlaegig bekannten blacklists ist das Netz auf jeden Fall nicht gelistet. In der Tat hatte ich selbst innerhalb der letzten 3 Monate 1x ein Spam-Mail aus diesem Netz erhalten. Eigentlich nichts Aussergewoehnliches, hin und wieder flutscht halt mal was durch bei diesen grossen Providern.

Mein privater Server bei Hetzner wird auch schon seit einigen Monaten von hotmail.com, live.com, etc. blockiert. Ich glaube, dass ganze Netblocks von Hetzner auf automatische Blacklisten gelandet sind. Meine Vermutung ist, dass Hetzner ein spammer-hosting Problem hat. Google hat uebrigens auf "mailop" (eine Mailing-Liste fuer Mail Hoster) gesagt, dass es bei ihnen auch passieren kann, dass ganze netblocks blockiert werden: https://www.mail-archive.com/mailop@mailop.org/msg01042.html Vielleicht koenntest du mit IPv6 versuchen. Oder auch ein Versuchswert ist DMARC. Oder die Mails ueber eine andere IP routen...
