Cisco Semiannual IOS Security Advisory http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar14.html
Let's Finally "Nail" This Port 5000 Traffic - Synology owners needed.
We have written a couple diaries about port 5000 traffic, and received plenty of packet captures. But we still need to get all the pieces together to see what the "end game" is with these attacks. Here is what I found so far from our honeypot:
- a lot of the port 5000 traffic is spoofed.
I do receive "SYNs" from an IP, and my honeypot responds with a SYN-ACK, but then I get a reset back with a very different TTL.
- the once that connect, send a couple different requests (a.b.c.d is the address of the honey pot)
GET / HTTP/1.1
Accept-Encoding: identity
Host: a.b.c.d:5000
GET /robots.txt HTTP/1.1
Accept-Encoding: identity
Host: a.b.c.d:5000
GET / HTTP/1.1
Accept-Encoding: identity
Host: a.b.c.d:5000
GET /webman/info.cgi?host= HTTP/1.0
Host: a.b.c.d
User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.107 Safari/537.36
GET /webman/info.cgi?host= HTTP/1.0
Host: a.b.c.d:5000
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Content-Type: application/x-www-form-urlencoded
Content-Length: 0
The last two requests point to a Synology vulnerability. But, just like the others, it appears to be more a "Fingerprinting" request trying to figure out if the system is vulnerable.
If you have a Synology Diskstation, I would very much appreciate if you could send these requests to the disk station, and send me a packet capture of the response. This way, I can improve my honeypot to respond "correctly". Please let me know what software version you are running.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
