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...

#PegasusProject
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?
#PegasusProject
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.
#PegasusProject
rsf.org/en/news/after-… ImageImageImage
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.

Statement: US Gov must impose consequences in light of latest revelations of spyware misuse.

Reps @Malinowski @RepKatiePorter @JoaquinCastrotx @RepAnnaEshoo ImageImageImage

NEW: @USTreasury just de-sanctioned 3 foreign mercenary spyware execs.

Puzzling.

Just 2 years ago Predator spyware was pointed at🇺🇸American congresspeople @RepMcCaul & @SenJohnHoeven.

And recent research suggests Predator is still active around the globe. 1/Image
Image
Image
Image
2/ NSO Group has bigger name recognition, but Intellexa's reputation for reckless proliferation of cyber capabilities is unmatched.

The pile of Predator abuses is enormous.

And they got repeatedly caught used against Americans by foreign govs.

3/ Ultimately Intellexa flew very close to the sun.

Their CEO Tal Dilian regularly boasted of their activities.

And then? Just last year they got sanctioned for their pattern of conduct.

Comprehensively.

Including key reported enablers of their activities like Sarah Hamou... Image

WHOA: Predator spyware discovered in 🇵🇰#Pakistan.

+ a leak shows zero-click infections via... ads.

Yikes.

Here are some more damming revelations as Intellexa, the shady, sanctioned spyware supplier gets exposed by @AmnestyTech & partners.. /1Image
Image
2/ First, a mercenary spyware myth has just been busted.

Because the leak shows an Intellexa employee directly accessing a customer deployment.

Prior to the #PredatorFiles leak, spyware companies basically always claimed they couldn't access customer deployments & didn't know what was going on there.

They used this to avoid responsibility & claim ignorance when faced with abuses.Image
3/ And it gets crazier. The leak shows Intellexa casually accessing a core backbone of Predator deployment of a government customer.

Seemingly without the gov's knowledge.

Suggests that Intellexa can look over their shoulder & watch their sensitive targeting.

Huge counterintelligence nightmare for customers.

And a giant liability red-flag for intellexa.Image

NEW: 🇨🇳Chinese hackers ran massive campaign by tricking Claude's agentic AI.

Vibe hacking ran 80-90% of the operation without humans.

Massive scale (1000s of reqs/sec).

Agents ran complex multi-step tasks, shepherded by a human.

Long predicted. Welcome to the new world.

Fascinating report by @AnthropicAI 1/Image
2/ The old cybersecurity pitch: unpatched systems are the threat.

The next generation concern might be unpatched cognition.

The attacker jailbroke the cognitive layer of @anthropic's Claude code, successfully convincing the system of false intent (that it was a security exercise)Image
Image
3/ One of the key points in @AnthropicAI's report is just how limited the human time required was to run such a large automated campaign.

Obviously powerful stuff, highlighting the impact of orchestration.

And concerning for the #cybersecurity world for all sorts of reasons, ranging from attack scale, adaptability & cost reductions...

But I keep thinking of the next step in this..

Putin has 3 identical offices his residences to hide where he is when he goes on TV.

But a cascade of tiny details gives the whole thing away.

Light switches, door handles, wood patterns & wall seams.

Truly epic OSINT.

h/t @alburovImage
Image
Image
Image
2. First, Putin had one office in his Novo-Ogarevo residence.

Then, paranoia kicked in. After he invaded Crimea it intensified.

Time for new digs, and elaborate deceptions to make him feel safe & project the image to Russians that he's an engaged Moscow-based leader. Image
Image
Image
Image
3/ For something that cost so much, the number of substantial differences & subtle tells is overwhelming.

Undoing the entirety of the enterprise of deception.

You have to assume that Intelligence services have known these tells for a long time.

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
