Or maybe it isn’t entirely clear who should get the report when remote access to an organization’s internal network is being sold in the cybercrime underground.
In a bid to minimize these scenarios, a growing number of major companies are adopting “Security.txt,” a proposed new Internet standard that helps organizations describe their vulnerability disclosure practices and preferences.

The idea behind Security.txt is straightforward: The organization places a file called security.txt in a predictable place — such as example.com/security.txt, or example.com/.well-known/security.txt. What’s in the security.txt file varies somewhat, but most include links to information about the entity’s vulnerability disclosure policies and a contact email address.
The security.txt file made available by USAA, for example, includes links to its bug bounty program; an email address for disclosing security related matters; its public encryption key and vulnerability disclosure policy; and even a link to a page where USAA thanks researchers who have reported important cybersecurity issues.
Other security.txt disclosures are less verbose, as in the case of HCA Healthcare, which lists a contact email address, and a link to HCA’s “responsible disclosure” policies. Like USAA and many other organizations that have published security.txt files, HCA Healthcare also includes a link to inf ..
