Nazdar.

Uz asi tyzden je moj server na blackliste. Zatial bol iba na mailspike bl. Ale od dnesneho rana je aj na spamhause.org. Tam som sa docital toto:

This IP address is infected with, or is NATting for a machine infected with the ZeroAccess botnet, also known as Sirefef. More information can be found from Wikipedia. It is most often used for bitcoin mining or click fraud, but as it contains a downloader portion, it can do anything.

If this IP address is a NAT gateway, it should be possible to find which computer on your internal network is infected by implementing a filter on your firewall to detect and log attempts to send UDP packets to the Internet with a destination port number of 16470.

REMEMBER: ZeroAccess is NOT an Email spamming tool. This detection was NOT because of spam.


Urobil som toto:
iptables -I OUTPUT -p udp --dport 16471 -j DROP
iptables -I OUTPUT -p udp --dport 16470 -j DROP
iptables -I OUTPUT -p udp --dport 16465 -j DROP
iptables -I OUTPUT -p udp --dport 16464 -j DROP

Staci? Neriesili ste niekto uz toto? Chodia aj mne maily napr. od abcd@mojafirma.sk na moj mail ale ja meno "abcd" na serveri nemam.

Dakujem ze kazdu radu. Port 25 mam na forwarde aj na outpute blokovany.

Vyzera ze je to zatial OK. Obavam sa skor ze niekto kto ma tento jeden spam moze mat aj viac. Cize moze sa stat ze zachvilu budem zase v BL. Blokujete nejako OUTPUT? Ja blokujem iba Incoming a povolujem na nom iba 25 SMTP,80web a 53 tcp + udp na DNS. Na forwarde blokujem 25 + tie co som pisal hore. A na OUTPUT iba tie co som pisal hore. Zatial cca 2 roky nebol problem.

Toto by mi pomohlo na vystopovanie SPAMera?

iptables -N LOGGING
iptables -A OUTPUT -j LOGGING
iptables -A LOGGING -m limit --limit 2/min -j LOG --log-prefix "IPTables-Dropped: " --log-level 4
iptables -A LOGGING -j DROP

OUTPUT je traffic ktory vznika na tom konkretnom stroji, a odchadza cez siet von. takze si si tym zablokoval spojenia z toho konkretneho routera (od loklanych aplikacii), nie spojenia ktore cez router prechadzaju. RTFM.

nie je lepsie konkretneho vinnika najst a odstranit, ako dropovat pakety?
iptables -I FORWARD -p udp --dport 16470 -j LOG --log-prefix "kamarat co posiela udp na port 16470"
a potom dropnut

asi poriesene? logy najdes vo /var/log
ak prevadzkujes server na linuxe, nebolo by odveci si nieco nastudovat, alebo nechat s linuxom pracovat niekoho kto aspon trochu vie co robi

Nazdar.

Log som vedel ze sa uklada do /var/log akurat ze som tam nemal nastavene vytvaranie Logov pre iptables. Dopisal som to do rsyslog.conf kedze ja mam redhat a hladal som syslog.conf. Ale tak ako hovorim este najst dalsieho SPAMera je tazsie kedze neviem port. Cez iptraf som pozeral ake porty sa vyuzivaju. 25 SMTP som nenasiel ziaden. Su tam bezne porty. Inak ako odhalit napr. port 53. Ved aj cez UDP 53 ci TCP funguje napr. Bonk (DoS) trojan horse also uses port 53(TCP).A je ich viac takych. Netstat -tapn aj to som skusal.
