VPNs are pricey snake oil.

Consumers are getting scammed by misleading marketing.

I've never met a user with an accurate understanding of just how modestly, if at all, VPNs address their security & privacy concerns.

Time for the industry to get regulatory scrutiny.
The VPN industry nurtures the impression that they actually do things like:

- Stopping malware (NOPE!)
- Hiding you from tracking (mostly NOPE, remember cookies, etc?)

They soak consumers for millions while creating a false sense of security.
The VPN industry is increasingly consolidated.

Can you trust the big companies with your data?

We don't know.

Some of the biggest players actually have a shady history with... exploiting users traffic.

Oh, and they own a bunch of VPN review sites.
cnet.com/tech/services-… Image
Everybody knows what VPNs work for: watching regionally blocked shows, etc.

Don't forget their starring role in censorship circumvention. (great!)

But the ongoing marketing-driven mass misunderstanding of what they do & don't do for privacy and security is unethical & harmful.
VPNs found a market because of other bad privacy situations salient to consumers:

They don't trust their ISPs. Often with good reason.

They don't trust advertisers & platforms either.

And they feel the tickle of surveillance as targeted ads follow them around the web.
Worried consumers are rightly unsure whom they can trust.

Enter VPN companies, who nurture & monetize the fear.

They have convinced masses of users to pay them to send traffic through servers that *they control.*

And provided rather limited value & transparency in return.
The VPN industry has created a mass of self-servingly biased security advice & guidance. And worse.

And it's leaving consumers worse off.

Try this experiment: google for VPN advice & take note how hard it is to figure out what the conflicts of interest are.
To be clear: this thread is about #BigVPN.

You know the names because you have watched a youtube video or listened to a podcast.

They are inescapable.

[I'm not talking about VPNs used in an enterprise setting, managed by your employer's IT team. Different animal]
High risk users (journalists, dissidents, politicians etc) also see #BigVPN's ads.

Like millions of consumers, they buy VPN services, concluding that this helps protect them.

And then they get hacked.

Sometimes I'm the person delivering the bad news.

It makes my blood boil.
We encountered just how badly #BigVPN had distorted users' security perceptions while focus grouping Security Planner.*

*A free expert-driven personalized online safety advice site.

We recently graduated it to the nonprofit Consumer Reports.
securityplanner.consumerreports.org
Working on @SecurityPlanner also meant getting mails from security advice sites... that refused to answer questions about who backed them.

I have my suspicions.

Did my thread make you want legit security advice? Have more qs about VPNs? Check it out.

securityplanner.consumerreports.org
Forgot to add: there are a handful of *good* commodity VPN players.

They communicate honestly, are transparent, and make an effort to educate their users & be corporate good citizens.

It must be incredibly frustrating for them to watch #BigVPN blast past in revenue & users.
I have a theory for why #BigVPN likes sponsorships & affiliates.

It's not just about audiences, it's about *avoiding liability.*

Creators..creatively pitch.

That may mean doing the dirty work of misinforming consumers.

But of course, it's arms-length from the VPN company.
Issues with #BigVPN's ads are neither anecdotal, nor isolated.

A recent large-sample paper makes the massive scale clear.

-Billions of estimated views.
-Many misleading claims & misinformed consumers.
-Undeclared conflicts.

BREAKING: NSO Group liable for #Pegasus hacking of @WhatsApp users.

Big win for spyware victims.

Big loss for NSO.

Bad time to be a spyware company.

Landmark case. Huge implications. 1/ 🧵Image
Image
Image
Image
2/ In 2019, 1,400 @WhatsApp users were targeted with #Pegasus.

WhatsApp did the right thing & sued NSO Group.

NSO has spent 5 years trying to claim that they are above the law.

And engaged in all sorts of maneuvering.

With this order, the music stopped and NSO is now without a chair.Image
Image
3/ Today, the court decided that enough was enough with NSO's gambits & efforts to hide source code.

Judge Hamilton granted @WhatsApp's motion for summary judgement against the #Pegasus spyware maker.

The judge finds NSO's hacking violated the federal Computer Fraud & Abuse Act (#CFAA), California state anti-fraud law #CDFA, and was a breach of contract.

What happens next? The trial proceeds only on the issue of resolving damages stemming from NSO's hacking.

NEW: US considering ban on @TPLINK routers.

Company has a majority of the US market share for homes & small biz.

Concerns stem from repeated use in cyberattacks from #China & concerns over supply chain security.

Reportedly an office of @CommerceGov has subpoenaed the company. 1/

Story by @heathersomervil @dnvolz & @aviswanathaImage

2/ @TPLINK has quickly grown market share, even as concerns have grown over vulnerabilities in the routers being used in #China-linked hacking operations.

wsj.com/politics/natio…Image
3/ As Microsoft's @MsftSecIntel reported earlier this year, for example, #TPLINK routers make up the bulk of the CovertNetwork-1658 attack infrastructure.

This operator was conducting so-called password spray attacks, and taking steps to be discrete.

The credentials are then used by multiple #China-based threat actors....

Use only end-to-end encrypted communications says @CISAgov.

YES!

End-to-end encryption is critical infrastructure for a safe society.

Plenty of other solid guidance for mobile users at risk here.

Let's look at their #iPhone & #Android-specific recs... 1/Image
Image
Image
2/ @CISAgov's top recommendation for Apple users is to✅ enable #LockdownMode

It's my top guidance for high-risk #iPhone users..

Because as researchers tracking sophisticated threats we see Lockdown Mode blunt advanced attacks...

Other solid guidance:

✅Protect your DNS
✅Disable fallback to SMS
✅Enroll in iCloud Private Relay
✅Trim App permissions.Image
Image
3/ @CISAgov's guidance for #Android starts from the unavoidable fact that many Android manufacturers truly don't respect users security or privacy.

So ✅pick a company that won't leave you insecure after 2-3 years.

Other good guidance here includes...
✅ Only use RCS with end-to-end encryption
✅ Using Android Private DNS
✅ Use Enhanced Protection for Safe Browsing
✅ Google Play Protect
✅ Manage permissions.

NEW: #China #Russia #Iran & #Israel are spying on 🇺🇸Americans using telecom weaknesses says @DHSgov

Deeply concerning on heels of #SaltTyphoon breaches.

All US carriers vulnerable to some extent.

We know this thanks to Sen @RonWyden's tireless work to expose #SS7 & #Diameter vulnerabilities.

Here's how they work...

Story by @josephfcox 1/Image

2/ Here's the thing about the global network for routing calls.

Requests are trusted by default. Whatever operator they come from!

Since requests can let you do things like intercept calls, texts & track phones locations...

...a lot of governments & some shady companies have come running.

All they needed was a "Global Title" which is not hard to get in some jurisdictions.

Result? A tidal wave from around the globe of shady requests for the purpose of spying on people.

Including Americans. In the US.

We @citizenlab exposed Circles, one such player...

Story: 404media.co/dhs-says-china…Image
3/ There's an active global market for companies whose product line revolves around abusing the trusting nature of call routing to conduct surveillance.

We @citizenlab ran scans & mapped deployments of this tech by one such player: Circles.

Circles had previously merged with NSO Group, which makes #Pegasus.

NEW: police in #Serbia caught unlocking activists phones with @Cellebrite's mobile forensic tools & planting spyware on them.

Incredibly troubling investigation by @AmnestyTech delves into how the Serbian authorities mix a toxic brew of repression out of homegrown + foreign mercenary spyware like #Pegasus + $CLBT's forensic tools possibly supplied as part of foreign assistance from #Norway. 1/

Read: amnesty.org/en/documents/e…Image

2/ From Traffic Stop to Spyware Victim...

As costs increase for zero-click spyware, expect to see authorities getting creative...

Rolling their own tech & finding novel ways to plant it on activists' devices with physical access.
3/ A favorite detail: a @Cellebrite exploit got caught & vuln patched.

This is what happens when your tech is abusively used against activists...

🚨NEW INVESTIGATION: Russia's 🇷🇺 FSB beat & detained this programmer.

They demanded he inform on contacts in #Ukraine.

When he was finally released, Kirill Parubets got his phone back.

It was bugged with spyware. 1/

Investigative collab by us @citizenlab w/@DeptFirst.Image
Image
2/ Russian authorities descended on Kirill Parubets & his spouse. Raiding their apartment.

Beating him for his passwords.

Accusation? Money transfers to #Ukraine.

Then they threw the couple into custody.

The #FSB threatened life imprisonment if he didn't agree to become an informant.

citizenlab.ca/2024/12/device…Image
Image
3/ When the couple was eventually released , Parubets was eventually able to pick up his devices from the #FSB at the dreaded Lubyanka building (former KGB HQ, also a prison).

As a programmer, he carefully scrutinized his returned devices & noticed a weird notification on his Android...Image
