Barclays Bank Using Internet Archive as CDN for JavaScript Files?
It's cute but probably just a consequence of a content editor at Barclays who has copy-pasted some old content.A technical solution could be to add a strict CSP policy but in general the problem is broader and applies to a lot of banks.The real issue is that banks (and it's not specific to Barclays) are loading JavaScript code from third-parties.The fact that it is InternetArchive (yet another Internet cache) is not more worrying than GoogleUserContent.com for example.Otherwise, the "asking money for redemption/forgiveness" part to Barclays is a bit borderline in my opinion.
