(*): ISC rating
  • We use 4 levels:
    • PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
    • Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
    • Important: Things where more testing and other measures can help.
    • Less Urt practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
    • The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threatatches.

Odd POST Request To Web Honeypot

I just saw this odd POST request to our honeypot's index page. Has anybody seen something like this? No idea what they are trying to accomplish.

Content-Type: application/x-www-form-urlencoded
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0; EIE10;ENUSMSN)\r\n
Host: [IP Address of Honeypot]
Content-Length: 364
Cache-Control: no-cache


The payload looks Base64 encoded, but decoding doesn't help much either. The payload also looks like the "+" (which would be a space if URL encoded) marks a deliminator.
