Reference a known malicious CSV list of I.P Addresses

(Ayoola Ayooluwa) #1

Hi, is it possible to reference a list on graylog. what i want to do is to compare my source addresses with a list of known malicious addresses i already have on a CSV file. In short, what i want to do is check if my source addresses are accessing any of the malicious addresses.

What’s the actual content of the file?

suspected malicious i.p addresses and i have close to 2000 rows.

For the Quote Character field, i used a space. whereas, the next i.p to check is on the next line. hope it isnt wrong?

Please provide examples. And a screenshot of Excel is not an example.

Just leave the default value (double quote).

Maybe for clarification:

The Lookup is a Key-Value lookup. In your case could be the value a second column that just contains “true” or what ever indicate. Then you can lookup the IP in the ipaddr column and the value need to be read from a second column. Having the key and the value in the same is currently not supported by the csv lookup adapter.
