Google is utilizing optical character recognition (OCR) strategies to crawl URLs present in YouTube movies—together with personal movies—in response to programmer Austin Burk, first reported by Bare Safety. Burk discovered an XSS vulnerability in a unique web site, which he was reproducing utilizing display seize software program as a part of a accountable disclosure package deal. After importing the video to YouTube, he discovered proof of crawling exercise with the person agent “Google-Youtube-Hyperlinks” in server logs on a system he controls.
In response to Burk, the URLs had been seen within the deal with bar through the video, which was uploaded to YouTube, however saved unlisted. Burk then made a non-public video to check the conduct, which occurred in the very same style because the unlisted video created for accountable disclosure.
Contemplating Google’s core product is search, it is smart that the corporate is at all times scanning the online. Google’s use of customers’ private exercise, together with searching historical past and placement, to focus on promoting and search outcomes is well-known. However YouTube’s assist article for video privateness settings makes no point out of this conduct, and Google’s assist article itemizing person agent tokens for his or her search crawlers additionally makes no point out of this crawler present.

Even when Google’s intentions are innocuous, that is probably very damaging. Burk proposes a state of affairs just like the XSS difficulty he was disclosing:
A safety researcher has discovered a important vulnerability in a web site, and has crafted a URL that can set off it, inflicting dangerous results to the web site. (e.g a SQL injection vulnerability that can drop the database tables).
Through the video, s/he makes point out that they won’t go to the URL as it might trigger hassle, however it’s displayed in order that the corporate they’re responsibly disclosing to can treatment it. They add it as unlisted to YouTube and submit their report. 5 minutes later, Google-Youtube-Hyperlinks comes alongside and sends two requests to the URL, triggering the SQL injection and rendering the location damaged.
Because of this, utilizing YouTube to host even personal movies for safety disclosures shouldn’t be advisable, because the integrity of the disclosure can’t be assured with Google’s search crawler probing inspected web sites. It’s tough to utterly fault Google for this exercise, as malicious actors may use YouTube to instruct unwitting victims into manually typing hyperlinks into their deal with bar, main them to viruses or illicit content material.
That mentioned, the abject lack of documentation or acknowledgement from Google about this in public documentation ought to make customers uneasy about how Google is utilizing knowledge uploaded to their companies.
TechRepublic contacted Google, however didn’t obtain a response by press time. We’ll replace this story if Google supplies a press release.
The massive takeaways for tech leaders:
- Google is utilizing optical character recognition (OCR) strategies to crawl URLs present in YouTube movies, together with unlisted and personal movies.
- Google’s assist pages for YouTube and Search Console make no point out of this conduct.
