Of the descriptions I read, the most interesting to me was the blurb provided by Facebook: Some provide information on the purpose of the crawler, while others just load the main page of the company in question. I manually reviewed the pages provided by each user-agent string above. This one has the dubious honor of being the first one that my ad blockers block at the domain level

SemrushBot - Another analytics company.

I didn’t realize how many of these there were these days

Qwantify - Another wannabe search engine.

MJ12bot - A business-focused data analytics service.

Facebook - We all know and (should) hate this big boy.

Exensa - Self-described as “…a very small French company specialized in large scale text data analysis.” that is creating a new search engine.

Among friendlies, we see various search engines and data analytics sources: Nine of these strings are “friendly” in that they identify the origin, while the other five do not.

Mozilla/4.0 (compatible MSIE 7.0 Windows NT 6.1 WOW64 Trident/6.0 ).Among these visits, there were 14 unique user-agent strings: In total, there were 39 visits to the hidden href token over the course of about five months. With this discovery, I’ll be splitting my analysis up into the analysis of the hidden href token visits (the smaller data set) and the retired token visits. These are not mutually exclusive, and there might be other reasons. Web crawlers scour prior versions/commit histories of Github content and visit links found there.Web crawlers cache versions of content (a la ) and periodically visit links present in older cached content.Web crawlers re-visit links that they visited in the past, regardless of whether the links exist in any current content.I can’t know exactly why the token is still being crawled, but a few possible reasons come to mind: This fact surprised me, since I removed the reference to the “” token from the page source back in March when I made the last post on this subject. There are more instances of the retired “” token than the active “ hidden ref” token. AnalysisĪs soon as I threw together a pivot table for the output and started looking from different perspectives, I learned something surprising: Since there were only a few I didn’t bother updating the script to handle these edge cases. I had to manually clean up some user-agent strings that contained commas (if you insert commas in your user-agent strings, you are an evil monster). Not efficient, but it got the job mostly done. O.write(re.findall('Memo : (.*)', element) + ',')Įlif re.findall('Source IP. # Loop through scanlist and drop values into CSV format O = open('/path/to/your/output.csv', 'w')

eml files in directory and store the interesting lines into scanlistįor file in os.listdir('/path/to/your/emails/'): # Create a list to store results of parsing emails

The CodeĪs Eric Conrad is fond of saying: if I typed it twice I should have scripted it once, so step two resulted in the below quick and dirty script: Step one should be self explanatory (if not, let me google that for you). eml file and pull out the interesting data

Write a Python 3 script to parse each.

That necessitated a few steps to get the data in a parsable format: I never got around to setting up a proper webhook receiver for the tokens, so I’ve just been slowly collecting them via emails that land in a mail folder I set up. I assumed that all the hits that have come in since March were for that remaining token… but as we will see in the analysis, that assumption was incorrect. I have played with a few canary tokens but since my prior post (March of 2019), I have only had one that is out in the wild in active content: the previously mentioned hidden href token.
