The Facebook Dilemma

November 1, 2018, 14:55(EDT) By Eric (a.k.a. TweakHound)

This topic has been making the rounds for a couple of days. I wanted to watch the entire thing before I passed it along.
The Facebook Dilemma is two, 50+ minute videos of a PBS Frontline special. It is the story of the dangers of Facebook. The first video deals more about the dangers to individuals. The second is about the dangers Facebook presents to society and democracies around the world. It then circles back to the dangers to individuals.
You’ll learn not only about these topics but about the stunning greed, arrogance, tone deafness, and outright deceit on these issues from the highest levels of Facebook.
In the end the only solution is to #DeleteFacebook.

“The promise of Facebook was to create a more open and connected world. But from the company’s failure to protect millions of users’ data, to the proliferation of “fake news” and disinformation, mounting crises have raised the question: Is Facebook more harmful than helpful? On Monday, Oct. 29, and Tuesday, Oct. 30, 2018, FRONTLINE presents The Facebook Dilemma. This major, two-night event investigates a series of warnings to Facebook as the company grew from Mark Zuckerberg’s Harvard dorm room to a global empire. With dozens of original interviews and rare footage, The Facebook Dilemma examines the powerful social media platform’s impact on privacy and democracy in the U.S. and around the world.”

Cold Boot Attack

September 13, 2018, 16:09(EDT) By Eric (a.k.a. TweakHound)

locks

Security flaw in ‘nearly all’ modern PCs and Macs exposes encrypted data
“A firmware bug means existing security measures “aren’t enough to protect data in lost or stolen laptops,” says new security research”
(Thanks Dan!)

Everything you need to know to is in the excellent paper:
F-Secure’s Guide To Evil Maid Attacks

Geeks have always known that once someone has physical access to your PC (or Mac, or phone), given enough time, it will be compromised.
Conduct yourself accordingly, especially on mobile devices. Given that, IMHO it is all about putting hurdles in place to slow an attacker down and frustrate them.
Here is what I tell my friends when they ask about mobile tech device security:
– Use a BIOS/EFI password.
– Use an OS password.
– Use a password manager.
– Encrypt your important docs.
– Cover your webcam. I use these: Laptop Camera Cover Set
– Delete those compromising pics of yourself and/or your significant other (and stop taking them).
– Keep your system up to date. This means both the OS and the firmware.
– Backup, backup, backup

In post-massacre Vegas, security policies clash with privacy values
&
Caesars Palace not-so-Praetorian guards intimidate DEF CON goers with searches [Updated]
“For safety and security, hotel team members will enter rooms and perform a standard wellness check, even if you have opted out of housekeeping services, posted a sign on your door, or otherwise refused team member entry. You may be asked to leave the hotel, if you do not comply with this company policy,”
Blog Post from Marc Rogers “who leads DEF CON’s security team”.
“I do not support or endorse these room searches or how they are executed. I sympathize with the challenge these hotels are facing but believe they need to take a harder look at the efficiency, impact and long term cost of this strategy.
We MUST NOT let our hotels become like our airports. If we do, then the terrorists win.
”
Everything you do outside your room is filmed in Vegas, I get that. But inside your room should be another story. I had money stolen out of my hotel room by the maid 20 plus years ago. I haven’t allowed housekeeping in my room since. You come in my room unannounced and we are going at it.

Blue light from phone screens accelerates blindness, study finds
“Scientists say they have found how blue light from smartphones, laptops and other digital devices damages vision and can speed up blindness. Research by the University of Toledo in the US has revealed that prolonged exposure to blue light triggers poisonous molecules to be generated in the eye’s light-sensitive cells that can cause macular degeneration – an incurable condition that affects the middle part of vision.”
My S7 has a blue light filter and I am experimenting with it. Apple calls their blue light filter Night Shift.

Email Encryption Vulnerable

May 14, 2018, 08:29(EDT) By Eric (a.k.a. TweakHound)

“A group of European security researchers have released a warning about a set of vulnerabilities affecting users of PGP and S/MIME. EFF has been in communication with the research team, and can confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages.“

Attention PGP Users: New Vulnerabilities Require You To Take Action Now

Officially called “EFAIL”: https://efail.de/

A number of platforms are said to be vulnerable.
Quotes include, “Email is no longer a secure communication medium” and “can confirm that these vulnerabilities pose an immediate risk to those using these tools for email communication, including the potential exposure of the contents of past messages.”.
IMHO there seems to be a bit of hysteria going on about this this morning. On the other hand, I’m no security expert so what do I know.

Protonmail has stated,
“ProtonMail is safe against the efail PGP vulnerability. The real vulnerability is implementation errors in various PGP clients. PGP (and OpenPGP) is fine. Any service that uses our @openpgpjs library is also safe as long the default settings aren’t changed.”

I dunno, I never really believed anything on a computer was 100% secure or private and tend to conduct myself accordingly. Of course I’m just an average, boring dude so I’ve no idea why someone would waste the effort to read my email.

There is gonna be a lot more to read on this in the coming days.

AMD Spectre Mitigation Update

April 10, 2018, 14:23(EDT) By Eric (a.k.a. TweakHound)

windows security

“Today, AMD is providing updates regarding our recommended mitigations for Google Project Zero (GPZ) Variant 2 (Spectre) for Microsoft Windows users. These mitigations require a combination of processor microcode updates from our OEM and motherboard partners, as well as running the current and fully up-to-date version of Windows. For Linux users, AMD recommended mitigations for GPZ Variant 2 were made available to our Linux partners and have been released to distribution earlier this year…
Microsoft is releasing an operating system update containing Variant 2 (Spectre) mitigations for AMD users running Windows 10 (version 1709) today. Support for these mitigations for AMD processors in Windows Server 2016 is expected to be available following final validation and testing.
In addition, microcode updates with our recommended mitigations addressing Variant 2 (Spectre) have been released to our customers and ecosystem partners for AMD processors dating back to the first “Bulldozer” core products introduced in 2011.
AMD customers will be able to install the microcode by downloading BIOS updates provided by PC and server manufacturers and motherboard providers. Please check with your provider for the latest updates.
