- Start a fresh harvest on AReS
## 2021-12-29
- Looking at the top IPs and user agents on CGSpace's Solr statistics I see a strange user agent:
```console
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.{random.randint(0, 9999)} Safari/537.{random.randint(0, 99)}
```
- I found two IPs using user agents with the "randint" bug:
- 47.252.80.214 (AliCloud in the US)
- 61.143.40.50 (ChinaNet in China)
- I wonder what other requests have been made from those hosts where the randint spoofer was working... ugh.
- I found some IPs from the Russian SELECTEL network making thousands of requests with SQL injection attempts...
- 45.134.26.171
- 45.146.166.173
- 3.225.28.105 is on Amazon and making thousands of requests for the same URL:
```console
/rest/collections/1118/items?expand=all&limit=1
```
- Most of the time it has a real-looking user agent, but sometimes it uses `Apache-HttpClient/4.3.4 (java 1.5)`
- Another 82.65.26.228 is doing SQL injection attempts from France
- 216.213.28.138 is some scrape-as-a-service bot from Sprious
- I used my `resolve-addresses-geoip2.py` script to get the ASNs for all the IPs in Solr stats this month, then extracted the ASNs that were responsible for more than one IP:
```console
$ ./ilri/resolve-addresses-geoip2.py -i /tmp/ips.txt -o /tmp/2021-12-29-ips.csv
$ csvcut -c asn /tmp/2021-12-29-ips.csv | sed 1d | sort | uniq -c | sort -h | awk '$1 > 1'

3 3269
5 16509
5 49505
9 24757
9 24940
9 64267
```
- AS 64267 is Sprious, and it has used these IPs this month:
- 216.213.28.136
- 207.182.27.191
- 216.41.235.187
- 216.41.232.169
- 216.41.235.186
- 52.124.19.190
- 216.213.28.138
- 216.41.234.163
- To be honest I want to ban all their networks but I'm afraid it's too many IPs... hmmm
- AS 24940 is Hetzner, but I don't feel like going through all the IPs to see... they always pretend to be normal users and make semi-sane requests so it might be a proxy or something
- AS 24757 is Ethiopian Telecom
- I'm going to purge all these for sure, as they are a scraping-as-a-service company and don't use proper user agents or request robots.txt
- AS 49505 is the Russian Selectel, and it has used these IPs this month:
- 45.146.166.173
- 45.134.26.171
- 45.146.164.123
- 45.155.205.231
- 195.54.167.122
- I will purge them all too because they are up to no good, as I already saw earlier today (SQL injections)
- AS 16509 is Amazon, and it has used these IPs this month:
- 18.135.23.223 (made requests using the `Mozilla/5.0 (compatible; U; Koha checkurl)` user agent, so I will purge it and add it to our DSpace user agent override and [submit to COUNTER-Robots](https://github.com/atmire/COUNTER-Robots/pull/51))
- 54.76.137.83 (made hundreds of requests to "/" with a normal user agent)
- 34.253.119.85 (made hundreds of requests to "/" with a normal user agent)
- 34.216.201.131 (made hundreds of requests to "/" with a normal user agent)
- 54.203.193.46 (made hundreds of requests to "/" with a normal user agent)
- I ran the script to purge spider agents with the latest updates:
```console
$ ./ilri/check-spider-hits.sh -f dspace/config/spiders/agents/ilri -p
Purging 2530 hits from HeadlessChrome in statistics
Purging 10676 hits from randint in statistics
Purging 3579 hits from Koha in statistics
Total number of bot hits purged: 16785
```
- Then the IPs:
```console
$ ./ilri/check-spider-ip-hits.sh -f /tmp/ips-to-purge.txt -p
Purging 1190 hits from 216.213.28.136 in statistics
