BREAKING: massive, global leak of the targets of NSO Group's Pegasus spyware. *huge deal.*

Forensic investigation by @AmnestyTech
in collaboration with @FbdnStories reporters.

We @citizenlab conducted peer review.

Here's an explainer THREAD.
washingtonpost.com/investigations… Image
2. Background: the already-notorious NSO Group makes mercenary spyware to silently & remotely hack iPhones & Androids.

Many of their government customers are authoritarians.

Most cannot resist the temptation to target their critics, reporters, human rights groups etc. Image
3. More about leaked numbers & targets in a sec, but first you need to know:

@AmnestyTech just released a report with technical analysis of NSO's infrastructure... & analysis validating w/forensics that some phones were infected with Pegasus.

amnesty.org/en/latest/rese…
4. We @citizenlab independently peer reviewed @AmnestyTech's forensic methodology, including how they identify an infected phone.

Our review, led by my colleague @billmarczak, judged their forensics & research methodology to be SOUND.

citizenlab.ca/2021/07/amnest… Image
5. Now, to the findings: >50k numbers were leaked that are reportedly part of the infection & targeting workflow with Pegasus.

To help validate the relationship between these numbers & infections @AmnestyTech got consent to forensically examine a subset of the devices. Image
6. The @FbdnStories consortium worked w/the leaked phone numbers... what they found reveals 10 of NSO Group's customers insatiable intent to snoop.

And the massive scale of the operation.

- Mexico customer > 15,000
- Morocco > 10,000
- UAE > 10,00

Etc. Image
7. #SaudiArabia 🇸🇦 murdered & dismembered Jamal Khashoggi.

Jamal's wife was targeted with Pegasus spyware before the killing...

Then his fiancee was hacked multiple times just days after.

@citizenlab independently confirmed findings.

#PegasusProject
washingtonpost.com/investigations… ImageImageImageImage
8. #HUNGARY 🇭🇺

Ask the government for comment... get hacked.

Hungary's far-right PM Viktor Orbán is using Pegasus spyware to surveil & attack Hungary's independent media, like @direkt36, @panyiszabolcs, and many more.

Story: @shaunwalker7 theguardian.com/news/2021/jul/… ImageImageImageImage
9. #INDIA🇮🇳 Over 40 reporters, major opposition figures, serving ministers in the #Modi government, members of the security services and beyond are in the list.

Story to watch as the scandal unfolds there.

Story @svaradarajan @thewire_in
thewire.in/government/pro… Image
10. HUNDREDS of journalists around the globe are on the #PegasusProject list.

NSO Group's role in fueling the authoritarian assault on democratic values (like a free press) is coming into sharp focus

theguardian.com/world/2021/jul… ImageImageImageImage
11. NSO Group puts up a facade of caring about human rights, doing due diligence, etc.

This leak exposes the farce of that performance.

When your customers are dictators... they will do bad things. NSO knows this. We know it.

Now everybody knows it. Image
12. Continuing with cases.... in #FRANCE 🇫🇷

#PegasusProject list includes @edwyplenel, founder of independent news site @Mediapart, a reporter from @lemondefr, etc..

Story lemonde.fr/projet-pegasus… Image
13. in #Mexico 🇲🇽 Journalist Cecilio Pineda Birto was getting death threats for reporting on official collusion with a cartel capo...

...then his number showed up on the #PegasusProject list.

Then he was assassinated.
theguardian.com/news/2021/jul/… ImageImageImageImage
14. Bookmark this thread. Things are only getting started.

I'll be updating it with more cases & context as #PegasusProject revelations keep dropping.
15. REASON TO CARE #1

So, you didn't know today's #PegasusProject hacking victims personally.

But tomorrow? Who knows. You don't.

#NSOGROUP is aggressively pitching *local* cops, including in USA 🇺🇸

Pause. Think about the oversight at your local PD.

vice.com/en/article/889… ImageImageImageImage
16. REASON TO CARE #2:

Since all phones are vulnerable, #Pegasus spyware lets its autocrat-users *export fear*

They want want *you* to be afraid to criticize them.

Yes, you. A continent away. In a democracy.

Think about the implications.
7. REASON TO CARE #3:

Think only human rights defenders & journalists get hacked with #Pegasus?

Wrong.

Good chance officials responsible for the national security of YOUR country have been / will be targeted.

Example pic: 2019 #NSOGroup WhatsApp hack.
reuters.com/article/us-fac… Image
18. Know who else is saying #NSOGroup must be stopped?

Big tech.

These days they are hitting back hard against the mercenary spyware industry for hacking their products & users.

E.g. this thread by @wcathcart @WhatsApp's CEO.👇
19. #INDIA🇮🇳 (2/)

She accused the Chief Justice of India’s Supreme Court of sexual harassment.

Just days later:

Her phone. Her husband's phone. Their family members..

11 in total then showed up on the #PegasusProject list.

thewire.in/rights/ranjan-… ImageImageImage
20. #FRANCE 🇫🇷 Claude Mangin is campaigning for the release of her husband, a political activist, from a #moroccan prison.

She's in France.

Last month her iPhone 11 was silently hacked w/#Pegasus spyware. A second iPhone she borrowed? Also infected.
washingtonpost.com/technology/202… ImageImageImage
21. BREAKING: Americans 🇺🇸 including US. Gov. officials are on the #PegasusProject list...

...even the #Biden administration's lead Iran negotiator Robert Malley!

#NSOGroup is an urgent national security problem for the United States.
washingtonpost.com//national-secu… Image
22. #MEXICO 🇲🇽: At least *50 people* close to the president ... are on the #PegasusProject spyware list.

They were put there while he was campaigning.

-His wife
-Family members, drivers, doctor
-Aides, chief of staff
-Doctor...

Story theguardian.com/news/2021/jul/… ImageImage
23. Paul Rusesabagina inspired Hotel #Rwanda 🇷🇼

He's become a critic of the gov., and was recently thrown in jail.

His American 🇺🇸 daughter, while advocating for his release, has been incessantly surveilled w/ #Pegasus.

24. Policies to stop the global spyware catastrophe?

Experts @davidakaye & @MarietjeSchaake say:

- Immediate moratorium on sale & transfer
-Rule-of-law requirements on users
-Victims must be able to sue
-Global principles of conduct

#PegasusProject
washingtonpost.com/opinions/2021/… ImageImageImageImage
25. #INDIA 🇮🇳 (3/) Rahul Gandhi was Prime Minister #Modi's main opponent in the 2019 nat'l elections.

During the campaign, 2 of his phones were put on the #PegasusProject list, and 5 of his friends & fellow Congress party officials.

theguardian.com/news/2021/jul/… Image
26. #NSOGroup & #Pegasus spyware customers are issuing panicky, fairy-tale denials.

Here's my take.

#PegasusProject
27. BREAKING: 10 prime ministers, 3 presidents & a king on the #PegasusProject spyware list.

Included, French president @EmmanuelMacron
🇫🇷

Crystal clear: #NSOGroup is a global national security threat.

Story: washingtonpost.com/world/2021/07/… Image
28. #NSOGroup, after courting a lot of press, is suddenly not interested in talking....

So begins the hope-this-dies-down phase of crisis management?

29. NEW "there's gotta be some accountability for spies-for-hire"

Senator @RonWyden to Senate Intelligence Committee yesterday in light of #PegasusProject revelations about #NSOGroup spyware.
Full:
30. NEW: 1st legal complaint from #Pegasus victims over latest spyware revelations has landed in France 🇫🇷

Brought by 2 journalists, supported by press freedom org @RSF_inter

Their statement says more complaints inbound.

31. NEW: Dalai Lama's inner circle on the #PegasusProject list. (He's not thought to carry a phone)

Happened in period before & after a private meeting with @BarackObama.

#India🇮🇳 suspected as #NSOGroup #spyware client responsible.

Report: theguardian.com/news/2021/jul/… ImageImageImageImage
32. NEW: While #NSOGroup is trying to distract you with a counter narrative...

Here are #Indian 🇮🇳 Police barging into the offices of one of the #PegasusProject media outlets. 👇
35. TODAY: @WhatsApp CEO @wcathcart rubbishes #NSOGroup's denials:

- #PegasusProject reporting consistent w/targeting in #NSOGroup's 2019 attack on WhatsApp users.
- Points out: in *only* 2 weeks 1.4k numbers were confirmed targeted in 2019. Do the math.

theguardian.com/technology/202… ImageImage
36. BIG DEAL: today @WhatsApp CEO @wcathcart *publicly confirmed* that senior national security officials of US allies🇺🇸 were targeted with #Pegasus spyware in 2019.

Clear message: #NSOGroup spyware is a national security threat.

By @skirchy theguardian.com/technology/202… Image
37. Taking #NSOGroup's denials at face value?

CEO: "you won't reach 50,000 #Pegasus targets since the company was founded"

FACT: there were >1,400 *confirmed* targets in just 2 weeks in 2019 per @WhatsApp.

At this rate NSO would have easily reached 50k+
calcalistech.com/ctech/articles… Image
38. Not familiar with the 2019 #NSOGroup attack on @WhatsApp?

#Pegasus spyware was used to target people via WhatsApp in 2019. WhatsApp spotted it, quickly shut it down, notified all targets...and then *sued* NSO.

We @citizenlab helped investigate.
washingtonpost.com/opinions/2019/…
39. "A.Q. Khans of the cyber world"

🇺🇸 US lawmakers just came out swinging against mercenary hacking company #NSOGroup.

NEW: Ex exec at premier private cyber weapons contractor to US accused of selling eight trade secrets to buyer in Russia.

I think this = exploits.

Very bad: at minimum would give adversaries a blueprint for detecting the tip of the spear of US/Allied cyber ops..

Wild story 1/Image
Image
2/ A watch collection studded with fake rolexes...

...is allegedly part of Peter "doogie" Williams haul from selling the hacking labs' secrets.

documentcloud.org/documents/2619…Image
3/ While doogie's watch collection is a joke, the questions couldn't be more serious:

Were cyberweapons paid for by American taxpayers also turned against us?

Were service members, officials, or civilians at physical risk? When was this breach first suspected? Who knew what? When?Image

WARNING: seeing a lot of phishing against @Signal users.

Did you get a message like this?

Don't engage! It's an attempt to steal your account.

Your account is safe & chats are private, but you should use Signal's option to Report Spam & Block. 1/Image
2/ You can make the attackers life harder by clicking Report.

Background: Like any popular secure messaging app, Signal users sometimes get targeted by spam & phishing attempts.

Often, attackers guess large numbers of usernames / phone numbers & send out message requests...Image
3/ Take a minute to remind yourself how message requests & blocking work on @Signal.

A "damaging" leak of tools from a five eyes exploit developer?

Concerning. We need to know what's under this rug.

Big picture: "trusted, vetted" private sector players offensive cyber are not immune to losing control of tooling... with national security consequences 1/
2/ If true, a tooling leak at boutique firm Trenchant wouldn't be the first time that exploits from commercial offensive vendors wind up... in the wrong place.

Many questions.

In the meantime. Remember when Russian APT29..was caught with exploits first used by NSO & Intellexa? Image
Image
3/ There will always be a push for states to turn towards the private sector to meet offensive needs.

It's appealing. For some, it's very lucrative.

But in practice it brings unavoidable counterintelligence & national security downside risk that shouldn't be downplayed.

NOW: US court permanently bans Pegasus spyware maker from hacking WhatsApp.

NSO Group can't help their customers hack @WhatsApp, etc ether. Must delete exploits...

Bad news for NSO. Huge competitive disadvantage for the notorious company.

Big additional win for WhatsApp 1 /Image
Image
Image
Image
2/ Although the massive punitive damages jury award against NSO Group ($167m) got reduced by the court, as is expected in cases where it is so large (to 9x compensatory damages)...

This is likely cold comfort to NSO since I think the injunction is going to have a huge impact on the value of NSO's spyware product.

Comes as NSO Group has been making noises about getting acquired by a US investor & some unnamed backers...Image
Image
3/ NSO also emerges from the @WhatsApp v NSO case with just an absolute TON of their business splashed all over the court records..

E.g. check out the filings from Sept 15th 2025: courtlistener.com/docket/1639534…

WOW: @Apple donating a thousand new #iPhone17 s to civil society at-risk from mercenary spyware.

Good. This will help get Apple's most secure devices to where they need to be..

Truth is: those at the greatest risk from spyware are often least able to afford more secure phones 1/Image
2/ Memory Integrity Enforcement = big deal Radically hardens iPhones from common attack vectors.

So it was a bittersweet to see this announcement and think "yeah it's going to be a long time before highest risk ppl can get them."..
3/ You're reading this on a device that is probably more secure thanks to the vigilance of an activist somewhere...

Seems @Apple recognizes this & also knows how much of a game changer getting their most secure devices into the hands of civil society could be.

NEW: fresh trouble for mercenary spyware companies like NSO Group.

@Apple launching substantial bounties on the zero-click exploits that feed the supply chain behind products like Pegasus & Paragon's Graphite.

With bonuses, exploit developers can hit $5 million payouts. 1/Image
Image
2/ Apple is introducing Target Flags which speeds the process of getting exploits found & submitters rewarded.

This faster tempo is also a strike against the mercenary spyware ecosystem.

And the expanded categories also hit more widely against commercial surveillance vendors. Image
3/ If I contemplating investing in spyware companies I'd want to carefully evaluate whether their exploit pipeline can match what @apple just threw down.
