How to get root on Ubuntu 20.04 by pretending nobody's /home
By Kevin Backhouse
...
This blog post is about an astonishingly straightforward way to
escalate privileges on Ubuntu. With a few simple commands in the
terminal, and a few mouse clicks, a standard user can create an
administrator account for themselves. I have made a short demo video,
to show how easy it is.
It's unusual for a vulnerability on a modern operating system to be
this easy to exploit. I have, on some occasions, written thousands of
lines of code to exploit a vulnerability. Most modern exploits involve
complicated trickery, like using a memory corruption vulnerability to
forge fake objects in the heap, or replacing a file with a symlink
with microsecond accuracy to exploit a TOCTOU vulnerability. So these
days it's relatively rare to find a vulnerability that doesn't require
coding skills to exploit. I also think the vulnerability is easy to
understand, even if you have no prior knowledge of how Ubuntu works or
any security research experience.

Subject: Zoom lied to users about end-to-end encryption for years,
FTC says
Democrats blast FTC/Zoom settlement because users won't get compensation.
By Jon Brodkin
Zoom has agreed to upgrade its security practices in a tentative
settlement with the Federal Trade Commission, which alleges that Zoom
lied to users for years by claiming it offered end-to-end encryption.

TCPA Regulatory Update - FCC Releases Public Notice on Filing for
Voluntary STIR/SHAKEN Implementation Exemptions for Early Implementers
& Reviews Comments on Section 8 of the TRACED Act
Saturday, November 14, 2020
On October 1, 2020 the FCC adopted the Second Report and Order
implementing Caller ID Authentication. As described in our October
TCPA Digest, the Report and Order took a number of steps implementing
the TRACED Act, including, among others, requiring voice service
providers to either upgrade their non-IP networks to IP and implement
STIR/SHAKEN, or work to develop a non-IP caller ID authentication
solution; and providing a framework to file for extensions to the
implementation deadline for certain categories of providers, including
small voice service providers.

Phone and email scammers have pivoted during the pandemic. Here's how
to protect yourself.
After a dip in the spring, phishing attempts are back. Complaints about spam
text messages are up.

I hung up on my best friend.
I had received three robocalls in a row from what looked like
legitimate numbers, including one that started with that super-
annoying, high-pitched, childlike, "Hi there! How are you doing?" My
pal Lyn was call number four. Without noting the caller ID, I an-
swered, snapped, "Stop calling me!" and hung up. (She called back a
few minutes later, confused, but was completely understanding. She's
Canadian, so she's exceedingly polite.)
