- Call with Abdullah from CodeObia to discuss community and collection statistics reporting
## 2021-02-16
- Linode emailed me to say that CGSpace (linode18) had a high CPU usage this afternoon
- I looked in the nginx logs and found a few heavy users:
- 45.146.165.203 in Russia with user agent `Opera/9.80 (Windows NT 6.1; U; cs) Presto/2.2.15 Version/10.00`
- 130.255.161.231 in Sweden with user agent `Mozilla/5.0 (Macintosh; Intel Mac OS X 11.1; rv:84.0) Gecko/20100101 Firefox/84.0`
- They are definitely bots posing as users, as I see they have created six thousand DSpace sessions today:
```console
$ cat dspace.log.2021-02-16 | grep -E 'session_id=[A-Z0-9]{32}:ip_addr=45.146.165.203' | sort | uniq | wc -l
4007
$ cat dspace.log.2021-02-16 | grep -E 'session_id=[A-Z0-9]{32}:ip_addr=130.255.161.231' | sort | uniq | wc -l
2128
```
- Ah, actually 45.146.165.203 is making requests like this:
```console
"http://cgspace.cgiar.org:80/bitstream/handle/10568/238/Res_report_no3.pdf;jsessionid=7311DD88B30EEF9A8F526FF89378C2C5%' AND 4313=CONCAT(CHAR(113)+CHAR(98)+CHAR(106)+CHAR(112)+CHAR(113),(SELECT (CASE WHEN (4313=4313) THEN CHAR(49) ELSE CHAR(48) END)),CHAR(113)+CHAR(106)+CHAR(98)+CHAR(112)+CHAR(113)) AND 'XzQO%'='XzQO"
```
- I purged the hits from these two using my `check-spider-ip-hits.sh`:
```console
$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips -p
Purging 4005 hits from 45.146.165.203 in statistics
Purging 3493 hits from 130.255.161.231 in statistics
Total number of bot hits purged: 7498
```
- Ugh, I looked in Solr for the top IPs in 2021-01 and found a few more of these Russian IPs so I purged them too:
```console
$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips -p
Purging 27163 hits from 45.146.164.176 in statistics
Purging 19556 hits from 45.146.165.105 in statistics
Purging 15927 hits from 45.146.165.83 in statistics
Purging 8085 hits from 45.146.165.104 in statistics
Total number of bot hits purged: 70731
```
- My god, and 64.39.99.15 is from Qualys, the domain scanning security people, who are making queries trying to see if we are vulnerable or something (?)
- Looking in Solr I see a few different IPs with DNS like `sn003.s02.iad01.qualys.com.` so I will purge their requests too:
```console
$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips -p
Purging 3 hits from 130.255.161.231 in statistics
Purging 16773 hits from 64.39.99.15 in statistics
Purging 6976 hits from 64.39.99.13 in statistics
Purging 13 hits from 64.39.99.63 in statistics
Purging 12 hits from 64.39.99.65 in statistics
Purging 12 hits from 64.39.99.94 in statistics
Total number of bot hits purged: 23789
```
