The incredibly talented folks over at Bishop Fox were quite generous this week, providing a scanner for figuring out PAN-OS GlobalProtect versions. I’ve been using their decoding technique and date-based fingerprint table to keep an eye on patch status (over at $DAYJOB we help customers, organizations, and national cybersecurity centers get ahead of issues as… Continue reading

BIMI Up, Scotty! A look at Brand Indicators for Message Identification (BIMI) Adoption with R and the Alexa Top 1m
It seems that the need for MX, DKIM, SPF, and DMARC records for modern email setups were just not enough acronyms (and setup tasks) for some folks, resulting in the creation of yet-another-acronym — BIMI, or, Brand Indicators for Message Identification.

Acquisitions and Supply Chains: The Achilles’ heel of Product/Organizational Security
(A reminder to folks expecting “R”/”data science” content: the feed for that is at https://rud.is/b/category/r/feed/ if you don’t want to see the occasional non-R/datasci posts.) Over at the $WORK blog we posted some research into the fairly horrible Cisco RV320/RV325 router vulnerability. The work blog is the work blog and this blog is my blog… Continue reading

Phishing is [still] the primary way attackers either commit a primary criminal act (i.e. phish a target to, say, install ransomware) or is the initial vehicle used to gain a foothold in an organization so they can perform other criminal operations to achieve some goal. As such, security teams, vendors and active members of the… Continue reading
