The DoJ just busted a massive scam involving North Korean IT workers infiltrating major US companies.

They had some help in the US and were posing as remote freelancers to siphon off money and sensitive info.

Holy crap, here's what we know:
How they operated:

North Korean operatives are stationed in countries like China, Russia, and parts of Eastern Europe and Southeast Asia.

They then use fake documents and buy accounts to get remote jobs in the States. Image
On May 16, the DOJ indicted five people connected to this scheme.

One is an Arizona woman who helped North Korean IT workers by validating stolen identities, making them look like US citizens. Image
This woman also hosted laptops from US companies to spoof locations

This bypassed any geofencing making it seem like the North Korean workers were based in the US. Image
The scheme has raked in millions of dollars in wages from over 300 companies.

This money likely supports North Korea's regime, including its nuclear weapons program, according to the FBI. Image
North Korea's government is highly motivated due to heavy international sanctions.

They've been behind major cyber heists like the $81 million stolen from Bangladesh Bank via the SWIFT system in 2016. Image
Facilitators, or "mules," are key players in this operation.

They manage multiple fake identities and handle risky tasks like job interviews and drug tests, then pass the credentials to the actual North Korean workers. Image
These facilitators make big money.

For example, a Ukrainian facilitator managed about 870 identities and hosted 80 computers, earning over $900,000 over six years. Image
The IT workers, often highly skilled, work under harsh conditions with strict oversight.

Their activities include cryptojacking, targeting security researchers(!!!), and other cyber attacks to fund the regime. Image
How does your company verify remote worker identities? Would your process stand up to this threat?

Hackers are using Google Tag Manager (GTM) to inject credit card skimmers into E-commerce sites.

At least 6 compromised sites identified so far. Here's what we're seeing. 👇
Malicious GTM script reference (GTM-MLHK2N68) stored in Magento's cms_block.content table.

Attackers using GTM as delivery mechanism to bypass security controls. Image
Obfuscated JS skimmer activates on checkout pages, exfiltrating card data to C2 domain eurowebmonitortool[.]com.

Additional persistence achieved via PHP backdoor in media/index.php allowing remote code execution through base64-encoded commands.

Gives attackers ongoing access post-cleanup.Image

Hackers claim to have compromised Gravy Analytics, exposing millions of smartphone location records—including data sold to U.S. government agencies.

This could be the first major breach of a location data broker. Here’s what you need to know 👇
Potential impact:
- Precise GPS coordinates + timestamps on millions of people
- User movement classifications ("LIKELY_DRIVING")
- Customer lists (Apple, Uber, Equifax & more)
- Root access to Gravy's servers, control of domains, and Amazon S3 buckets Image
For years, firms like Gravy have sold location data to military, DHS, and even the FBI. Now hackers claim to have access dating back to 2018.

Potential risks:
- De-anonymization of individuals
- Tracking high-risk people
- Exposure of schools, clinics, and more

New series of Palo Alto Networks vulnerabilities, chained together for a bad time.

“We find that a simple request to that exact endpoint over the web service resets the admin password.”

Well, I don’t like the sound of that… 🧵 Image
First up -

CVE-2024-9464 is an OS command injection vulnerability in Palo Alto Networks Expedition

This allows an authenticated attacker to run arbitrary OS commands as rootImage
Next -

CVE-2024-9465 is an SQL injection vulnerability in Palo Alto Networks Expedition

This allows an unauthenticated attacker to reveal Expedition database contents, such as password hashes, usernames, device configurations, and device API keys.Image

So U.S. uses backdoors in it's own Internet providers to spy on it's citizens.

China says "don't mind if we do" and backdoors the backdoors.

They sat for months undetected on the U.S. wiretap system for Verizon, AT&T, and more...
Who watchers the watchers? Turns out China does.

Woah. Millions of cars can be hacked just by knowing the license plate number.

This is done through a simple web app bug too, no complicated car hacking involved.

I also don't think it's fixed yet... 🧵 Image
The bug seems to impact all Kias right now and the researchers didn't disclose a PoC since it isn't fixed but it's been 90 days since disclosure so they're talking about it. Image
With just a license plate number, they found a way to use the web portal that dealers and customers use to setup smart car features to ...do a lot more.

Including unlocking, tracking location, even starting the car. Image
