*Student Worker Position in the Mozilla Firefox Application Security Team*

I'm hiring for a part-time student role in Mozilla's Firefox Application Security team in Berlin/Germany (remote possible). We are trying to reach students from a broad range of backgrounds, not only people who already see themselves as "security people". It is required that applicants are enrolled in a university in Germany.

NEW: Researchers have identified extensive spying campaigns abusing well-known weaknesses in the global cellphone infrastructure to track and locate targets.

Two (unnamed for now) surveillance vendors, whose customers are likely government agencies, were allegedly behind these spy campaigns.

The research exposes an industry that remains still largely in the shadows, armed with tech that can track people without the need to use spyware such as Pegasus.

A pretty significant change in resolver behavior is proceeding:

"[...] BIND 9 is switching to a parent-centric model of delegations. [...] The NS records in the child domain will be treated as normal DNS records and returned as authoritative data, but they will no longer overwrite the delegation data for the domain."

So much of what you may have learned about how #DNS works around the turn of the century is now out of date.

Getting serious ADHD and building software nobody asked.
