Lazarus Group Attack Vulnerability Calculator
How Vulnerable Are You to Lazarus Group Attacks?
The Lazarus Group doesn't break cryptography—they trick humans into approving fraudulent transactions. This calculator estimates your vulnerability based on security measures against frontend manipulation and social engineering.
Security Measures Implemented
Select security measures you have in place to protect against Lazarus Group attacks:
Prevents UI manipulation by showing exact transaction details
Physical confirmation required for high-value transactions
Requires multiple authorized users to approve transactions
Physical separation of signing keys to prevent manipulation
Protects against social engineering tactics like fake job offers
Prevents malware installation through fake trading apps
Offline storage for majority of funds
On February 21, 2025, a single digital transaction stole $1.5 billion from Bybit-one of the largest cryptocurrency exchanges in the world. It wasn’t a glitch. It wasn’t a hack from some anonymous script kiddie. It was a precision strike by the Lazarus Group, North Korea’s most dangerous cyberwarfare unit, and it marked the biggest cryptocurrency heist in history.
This wasn’t their first time. And it won’t be their last.
Lazarus Group doesn’t break into systems with brute force. They don’t flood networks with malware. They wait. They watch. They build trust. Then they make you authorize the theft yourself.
How Lazarus Group Steals Billions Without Breaking a Single Lock
Most people think of hackers as people typing fast in dark rooms, bypassing firewalls with complex code. Lazarus Group operates like spies in a heist movie. They don’t crack the vault-they convince the guard to hand over the key.
The Bybit heist followed a four-step playbook:
- Spear phishing: Attackers targeted employees with fake job offers, fake security alerts, and LinkedIn messages that looked like they came from trusted colleagues. One employee clicked a link. Another opened a PDF. That was all it took.
- Frontend manipulation: Once inside, they didn’t touch the cold wallets-those are offline and locked down. Instead, they injected malicious code into Bybit’s own user interface. When CEO Ben Zhou approved what he thought was a routine transfer of Ethereum, the software quietly changed the destination address. The transaction looked legitimate. It even showed the right amount. But the money went to Lazarus.
- Multi-signature bypass: Bybit used a 3-of-5 multi-signature system, meaning five people had to sign off on large transfers. Lazarus didn’t crack the keys. They tricked three signers into approving the same fraudulent transaction by making the interface show false confirmation screens.
- Fund laundering: They moved the stolen Ethereum through decentralized exchanges, converted parts into Bitcoin and Dai, and mixed it with funds from other heists. Some coins were held for months, waiting for heat to die down.
This isn’t just clever. It’s terrifying. Multi-signature wallets were designed to prevent exactly this kind of attack. Yet Lazarus didn’t need to break them. They just needed to fool the people using them.
The Pattern: Five Major Heists in 104 Days
After Bybit, the attacks didn’t stop. They accelerated.
Between June and September 2025, Lazarus Group pulled off at least five confirmed attacks:
- $100 million from Atomic Wallet
- $37.3 million from CoinsPaid
- $60 million from Alphapo
- $41 million from Stake.com
- $54 million from CoinEx (suspected)
That’s over $290 million stolen in less than four months. And that’s just what we know about.
What’s even more disturbing is how they link these attacks. Blockchain analysts from Elliptic found that funds from Stake.com were mixed with money from Atomic Wallet. CoinEx thefts used wallet addresses previously tied to Stake.com. They’re not just stealing-they’re building a criminal supply chain, blending stolen coins across platforms to erase their trail.
This isn’t random. It’s strategic. Every theft feeds into a larger laundering operation designed to avoid detection by U.S. Treasury sanctions trackers and blockchain forensics firms.
How They Get Inside: Beyond Phishing Emails
Lazarus Group doesn’t rely on old-school spam. They’ve upgraded.
One of their subgroups, called TraderTraitor, creates fake cryptocurrency trading apps-apps that look like legitimate tools used by traders. You download them. You use them. They even work well. Then, during a routine software update, they silently install MANUSCRYPT, a remote access trojan that scans your device for wallet keys, seed phrases, and login credentials.
They also target security researchers on LinkedIn. They send connection requests. They chat about blockchain security. They share papers. They build rapport. Then, months later, they send a link to a "research collaboration tool"-a poisoned PDF or web app that gives them full access to the victim’s system.
This isn’t hacking. It’s social engineering at a state-sponsored level. They don’t need to outsmart your firewall. They just need to outsmart you.
History of Blood: From Ronin to AppleJeus
The Bybit heist was record-breaking, but it wasn’t their first big win.
In 2022, they stole $620 million from Ronin Network, the blockchain behind the popular game Axie Infinity. How? A fake job offer PDF. A single employee opened it. The malware installed itself. The attackers accessed the validator keys. Done.
Back in 2017-2018, they targeted Bitcoin and Monero users in South Korea with malware that disguised itself as a crypto wallet app. They called it AppleJeus. It looked like a real wallet. It even synced with real blockchains. But every time you signed a transaction, it sent a copy to their servers.
Each attack got smarter. Each one used new tricks. Each one stole more.
What’s consistent? They always go for the weakest link: the human.
Why Cryptocurrency Exchanges Keep Getting Hit
Exchanges spend millions on security. They use cold storage. They have multi-sig. They hire ex-CIA analysts. Yet Lazarus still wins.
Here’s why:
- Cold wallets aren’t invincible: They’re only safe when untouched. Every time you move funds from cold to hot storage, you create a window of vulnerability. Lazarus waits for those moments.
- Multi-sig is broken by UI: If the interface shows you the wrong address, you’ll approve it. No amount of cryptography can fix bad user experience.
- Employees are the target: No system is stronger than its weakest employee. And Lazarus spends months grooming targets.
- Law enforcement can’t keep up: North Korea doesn’t have extradition treaties. The hackers operate from servers in China, Russia, and Southeast Asia. Even when funds are traced, no one gets arrested.
After the Bybit hack, the exchange recovered $40 million by working with blockchain analysts. They restored all user funds. But that’s not a victory. It’s damage control. The attackers still got $1.46 billion. And they’re already planning the next one.
What Can You Do? (If You’re an Exchange, Trader, or Just Caring)
If you run an exchange: upgrade your UI security. Add real-time transaction verification. Require secondary confirmation via hardware tokens-not just email or SMS. Train staff like they’re in a warzone. Assume every message is a trap.
If you’re a trader: never use browser extensions from unknown sources. Never download wallet apps from third-party sites. Use hardware wallets. Never enter your seed phrase on any website-even if it looks real.
If you’re just trying to understand the threat: realize this isn’t about crypto being insecure. It’s about humans being vulnerable. And Lazarus Group has turned that vulnerability into a national revenue stream.
North Korea’s nuclear program is estimated to cost $1 billion per year. Lazarus Group stole $1.5 billion from Bybit in one day. That’s not crime. It’s economic warfare.
The Bigger Picture: Is Crypto Safe From Nation-States?
The crypto world was built on the idea that it could be immune to government control. But now, governments are using crypto to control the world.
Lazarus Group proves that decentralized systems can be weaponized by centralized powers. They exploit the very openness that makes crypto valuable-the lack of central oversight, the global reach, the pseudonymity-to fund a regime under international sanctions.
There’s no technical fix. No algorithm can stop a human from being tricked. No smart contract can prevent a CEO from approving a fake transaction.
The only defense is awareness. Training. Skepticism. And the hard truth: if you’re handling crypto, you’re not just managing money. You’re managing national security.
Lazarus Group isn’t going away. Their funding depends on it. And until exchanges, regulators, and users treat social engineering like the existential threat it is, these heists will keep happening.
Next time you hear about a crypto hack, don’t ask: "How did they break in?"
Ask: "Who did they convince?"
Is the Lazarus Group still active in 2025?
Yes. The Lazarus Group is more active than ever. Between June and September 2025 alone, they carried out at least five confirmed cryptocurrency heists totaling over $290 million, including the $1.5 billion Bybit breach in February. Their operational tempo has increased significantly, with attacks targeting exchanges, wallets, and DeFi platforms worldwide.
How does Lazarus Group bypass multi-signature wallets?
They don’t bypass the cryptography. They bypass the people. Multi-signature systems require multiple authorized users to approve a transaction. Lazarus manipulates the user interface to show false transaction details-like a different recipient address or incorrect amount. When users approve what looks like a legitimate transfer, they’re actually signing off on a malicious one. The system works perfectly; the human doesn’t.
What is the connection between Lazarus Group and North Korea’s nuclear program?
The Lazarus Group operates under North Korea’s Reconnaissance General Bureau, the country’s main intelligence agency. Their sole mission is to generate revenue to fund Pyongyang’s banned nuclear weapons and ballistic missile programs. Cyber theft is their preferred method because it’s low-risk, high-reward, and nearly impossible to trace back to the state. The $1.5 billion Bybit heist alone could fund North Korea’s nuclear budget for over a year.
Can cryptocurrency exchanges protect themselves from Lazarus Group attacks?
Yes, but not with technology alone. Exchanges need to overhaul their human security protocols. This includes mandatory security training for all staff, real-time transaction verification with hardware tokens, limiting access to signing keys, and using air-gapped confirmation systems. Frontend security-how the interface displays transactions-must be hardened to prevent manipulation. Even the most advanced multi-sig systems fail if users are tricked into approving fake transactions.
Why do Lazarus Group hackers target LinkedIn and fake job offers?
Because cybersecurity awareness has made traditional phishing less effective. Lazarus has shifted to long-term social engineering. By posing as recruiters on LinkedIn, they build trust with security professionals, researchers, and exchange employees over weeks or months. Once trust is established, they send a seemingly legitimate file or link-like a job application or research tool-that installs malware. This method is far more successful than mass email spam.
Are Bitcoin and Ethereum equally vulnerable to Lazarus Group attacks?
Yes. Lazarus targets any cryptocurrency that can be easily converted into cash or used in laundering. They stole $1.46 billion in Ethereum from Bybit, but they also convert stolen assets into Bitcoin and stablecoins like Dai to avoid detection. Bitcoin’s liquidity and global acceptance make it ideal for laundering. Ethereum’s smart contract ecosystem allows for complex DeFi mixing. Both are equally useful to Lazarus-they just use them differently.
Has any member of the Lazarus Group been arrested?
No. Not a single member has been publicly arrested or extradited. The group operates from North Korea and uses proxy servers in China, Russia, and Southeast Asia. International law enforcement lacks jurisdiction, and North Korea refuses to cooperate. Even when blockchain analysts trace stolen funds to specific addresses, no legal action can be taken against the perpetrators.
What’s the difference between Lazarus Group and regular cybercriminals?
Regular cybercriminals want quick cash-ransomware, card theft, phishing scams. Lazarus Group is a state-sponsored unit with unlimited resources, long-term planning, and a mission: fund North Korea’s nuclear program. They spend months researching targets, use custom malware, avoid high-profile media attention, and launder funds across multiple blockchains. Their attacks are surgical, patient, and politically motivated-not financially opportunistic.

November 6, 2025 AT 07:45 AMIt’s wild how much we trust interfaces without questioning them. I’ve seen demo videos where even seasoned devs get fooled by fake transaction screens. The real vulnerability isn’t in the code-it’s in the muscle memory of clicking ‘Confirm’ without looking twice.
Robert Bailey
November 6, 2025 AT 23:14 PMYeah this is why I only use hardware wallets now. No phone, no browser, no luck for these guys. Simple as that.
Colin Byrne
November 7, 2025 AT 00:38 AMOh wow so the whole crypto world is just one big con game and we’re all the suckers? Of course the government is behind this-why else would they let it keep happening? They’re using it to control us. You think they care about your money? Nah. They want you dependent. This is just step one.
Chloe Walsh
November 8, 2025 AT 15:01 PMThey’re not even trying anymore. They just wait for someone to be tired enough to click ‘yes’ and boom 1.5 billion gone. I swear we’re all just one bad day away from losing everything
Whitney Fleras
November 9, 2025 AT 13:46 PMIt’s heartbreaking how much effort goes into security while the human element stays ignored. I’ve trained teams at my company to treat every link like a live wire. It’s not paranoia-it’s practice. And honestly? It’s the only thing keeping us alive.
Stephanie Tolson
November 10, 2025 AT 19:47 PMLook we can keep building better firewalls and multi-sig systems but until we teach people to pause before they click, nothing changes. This isn’t a tech problem-it’s a culture problem. We’ve trained ourselves to move fast and trust the system. That’s the trap.

November 11, 2025 AT 03:51 AMLet’s be real this is all a psyop. The real theft is happening through the Fed and central banks. Lazarus is just a distraction. They want you scared of crypto so you go back to fiat. This is how they control you. The whole thing is designed to make you give up your freedom for false security.

November 13, 2025 AT 02:36 AMWhy are you all acting surprised? Every exchange is a joke. They hire interns to manage keys and call it security. They think they're safe because they have 'cold storage' like that means anything. The real issue is incompetence dressed up as innovation
Jacque Hustead
November 13, 2025 AT 13:45 PMIt’s scary but also a wake-up call. Maybe this is what we needed to finally take human security seriously. No more rushing through approvals. No more skipping training. No more ‘it won’t happen to me’. We owe it to ourselves to slow down.
Angie McRoberts
November 15, 2025 AT 03:40 AMSo the CEO approved a transfer that looked legit… and we’re supposed to be shocked? Welcome to 2025. The only thing more dangerous than a hacker is a tired human with a good UI.
Chris Hollis
November 15, 2025 AT 13:06 PMLet’s not romanticize this. This isn’t a spy movie. It’s corporate negligence wrapped in a narrative. Exchanges knew the risks. They didn’t fix the UI. They didn’t train staff properly. Now they’re crying about state actors. The real villain is profit over safety.
Diana Smarandache
November 16, 2025 AT 21:34 PMWhat’s truly disturbing is that this was predictable. Every single detail here was outlined in white papers from 2021. The fact that no exchange acted means they prioritized growth over survival. This isn’t an attack-it’s a failure of leadership.
Wendy Pickard
November 17, 2025 AT 20:07 PMI work in fintech. We run monthly social engineering drills now. Employees get fake LinkedIn messages, fake job offers, fake updates. We track who clicks. The numbers are horrifying. If this is what happens in a controlled environment… imagine the real world.
Natalie Nanee
November 18, 2025 AT 09:16 AMThey’re not stealing from exchanges. They’re stealing from our trust. And once that’s gone, nothing else matters. Crypto was supposed to be free. Now it’s just another weapon in someone’s war.
Colin Byrne
November 19, 2025 AT 08:13 AMWait so you’re telling me the entire crypto industry is just a house of cards built on people who don’t read the fine print? And now you’re surprised when the wind blows? I told you all this would happen. You didn’t listen. You wanted to believe. You wanted the dream. Now the dream is dead. And it wasn’t the hackers who killed it. It was you. You kept clicking. You kept trusting. You kept pretending the system was safe. And now we’re all paying for it.
