The Orthodoxy of Password Managers

The cybersecurity orthodoxy has a sacred cow: password managers are unquestionably good, and everyone should use one.
We’ve preached this gospel for years, dismissing skeptics as Luddites who don’t understand basic security hygiene.

But the ongoing cryptocurrency thefts from the 2022 LastPass breach, still happening in late 2025—three years after the initial compromise—should force us to confront an uncomfortable truth:

our credential security architecture is fundamentally broken, and password managers as currently implemented may be making some attack scenarios worse, not better.

Recent Findings

TRM Labs’ recent analysis reveals that Russian cyber‑criminals have stolen over $35 million in cryptocurrency from LastPass vault backups, with attacks continuing well into 2025.

This isn’t just another breach story. It’s evidence that we’ve built a credential‑management system that:

creates honey pots for attackers, and
extends the blast radius of security incidents across years, not days.

The time has come to question whether centralized password management, as currently practiced, is actually the solution we thought it was.

Conventional Wisdom (and Its Limits)

Humans are terrible at passwords → we need tools to generate and store strong, unique passwords for every account.
Password managers encrypt everything with a master password, creating a secure vault that only you can access.
Use a strong master password, enable two‑factor authentication, and you’re protected against the chaos of credential reuse and weak passwords.

This narrative has become so dominant that questioning it feels heretical. Yet the LastPass cryptocurrency thefts expose the dangerous assumptions baked into this model.

The 2022 LastPass Breach – What Happened?

Attackers gained access to encrypted vault backups containing users’ most sensitive credentials, cryptocurrency private keys, seed phrases, and other high‑value secrets.
The company warned that weak master passwords could be cracked through brute force, but the security community largely treated this as a theoretical concern.
After all, users should have strong master passwords, right?

Three years later, we’re seeing the brutal reality:

Attackers have been systematically cracking weak master passwords and draining cryptocurrency wallets.
Blockchain evidence shows a methodical, multi‑year campaign that has netted tens of millions of dollars.
Russian exchanges like Cryptex and Audia6 have served as off‑ramps for laundered Bitcoin, creating a thriving ecosystem around LastPass vault exploitation.

Why Password Managers Can Be Dangerous

“Password managers create incredibly valuable targets.”

By design, they aggregate your most sensitive credentials into a single encrypted database.
When that database is compromised, every secret you’ve ever stored becomes vulnerable to a single cryptographic attack.

Traditional security advice assumes that compromise means immediate detection and response: you get breached, you rotate credentials, you move on. Password managers break this model in two critical ways.

1. Enormous Blast Radius

A single compromised vault can contain hundreds or thousands of credentials spanning years of digital activity.
The LastPass victims didn’t just lose access to one account—they lost cryptocurrency private keys, potentially exposing their entire digital wealth.

2. Indefinite Attack Window

Unlike a traditional breach where attackers need to act quickly before detection, stolen password‑manager vaults can be attacked offline for years.
The LastPass cryptocurrency thefts are still happening in 2025 because the encrypted vaults stolen in 2022 remain vulnerable to brute‑force attacks against weak master passwords.

This creates a perverse incentive structure: attackers can invest significant computational resources in cracking vaults because the potential payoff—access to hundreds of high‑value credentials—justifies the effort. We’ve accidentally created a business model for sustained, patient cryptographic attacks.

Industry Response (and Its Shortcomings)

The security industry’s typical response:

“Users should choose stronger master passwords. If people would just follow basic security hygiene, password managers would be perfectly safe.”

This response fundamentally misunderstands human behavior and organizational reality:

The LastPass breach affected over 30 million users.
Expecting all of them to choose cryptographically strong master passwords that can withstand years of offline brute‑force attacks is fantasy, not security planning.

More importantly, the master‑password model creates a single point of failure by design. Every password‑manager security model ultimately depends on users choosing and protecting a single secret that unlocks their entire digital life—violating basic principles of defense in depth and fault tolerance.

Real‑World Impact: Crypto Theft

Users who followed conventional password‑manager advice—storing crypto private keys and seed phrases in their vaults—found themselves maximally vulnerable when those vaults were compromised.
The very tool meant to protect their most sensitive secrets became the attack vector for losing them.

TRM Labs’ Blockchain Analysis – An Uncomfortable Truth

The attackers are sophisticated, well‑organized, and operating with apparent impunity:

Use of Russian exchanges, consistent money‑laundering patterns, and operational security measures suggest this isn’t opportunistic crime but an organized cyber‑criminal enterprise.
They routed $28 million through Wasabi Wallet’s CoinJoin mixing service and used sanctioned exchanges like Cryptex as off‑ramps.
Despite these obfuscation techniques, TRM Labs was able to track the flow of funds through “demixing” analysis, identifying patterns that revealed the underlying criminal infrastructure.

Takeaway

The LastPass cryptocurrency thefts illustrate a fundamental flaw in the current password‑manager paradigm:

Centralized vaults create high‑value, long‑lived targets.
Weak master passwords turn those targets into practically inexhaustible sources of profit for patient attackers.
The industry’s focus on “just pick a stronger master password” ignores the human factor and the structural risk of a single point of failure.

It’s time to re‑evaluate our reliance on centralized password managers and explore alternative models that distribute trust, reduce blast radius, and limit the attack window.

It suggests that password manager breaches aren't just creating opportunities for individual bad actors but funding organized cybercrime operations. The LastPass vaults have become a revenue stream for Russian cybercriminal groups, potentially financing other attacks across the ecosystem.

Before dismissing this analysis entirely, security professionals should acknowledge the strongest counterargument: password managers, despite their flaws, are still better than the alternative for most users. Without password managers, people reuse weak passwords across dozens of accounts, creating even worse security outcomes.

This argument has merit. The average user who chooses **"password123"** for every online account is certainly more vulnerable than someone using a password manager with a moderately strong master password. For routine account access, password managers provide meaningful security improvements over common user behavior.

But this misses the deeper point about risk management and appropriate tooling. We've been recommending a consumer tool designed for convenience passwords to secure high‑value assets like cryptocurrency private keys. This is like using a residential door lock to secure a bank vault.

The LastPass victims who lost cryptocurrency weren't making irrational security choices; they were following expert advice. The security community told them to store their most sensitive credentials in password managers. When those recommendations led to tens of millions in losses, we can't simply blame user error.

The LastPass cryptocurrency thefts should force us to reconsider our fundamental approach to credential security. Instead of debating whether **LastPass**, **1Password**, or **Bitwarden** is better, we need to question whether centralized credential management is the right model at all.

For high‑value assets like cryptocurrency, we need purpose‑built security architectures that assume breach and design for containment. This might mean:

- Hardware security modules for private‑key storage  
- Multi‑signature wallets that require multiple authorization factors  
- Air‑gapped systems that never touch networked computers  

For routine password management, we might need federated approaches that distribute risk instead of concentrating it. Instead of one encrypted vault containing everything, users might maintain separate credential stores for different risk categories, reducing the blast radius of any single compromise.

The goal isn't to eliminate password managers but to **right‑size** their role in our security architecture. They're useful tools for managing routine website passwords, but treating them as universal solutions for all credential management needs has created the exact attack scenarios we're seeing play out in the LastPass case.

The cybersecurity industry has spent decades optimizing for user convenience over security resilience. Password managers represent the apex of this philosophy; they make security easier by hiding complexity behind a single master password.

But the LastPass cryptocurrency thefts reveal the hidden costs of this convenience‑first approach. By aggregating credentials and extending attack windows, password managers can amplify the impact of security breaches rather than containing them.

The Russian cybercriminals systematically exploiting LastPass vaults understand this better than most security professionals. They've built a business model around the architectural vulnerabilities we've ignored in our rush to make security more convenient.

Three years after the breach, LastPass users are still losing cryptocurrency because we designed a system that prioritizes ease of use over resilience to persistent attacks. The **$35 million** stolen so far represents not just individual losses but a systemic failure of our credential security model.

The question isn't whether password managers are good or bad; it's whether we're ready to acknowledge their limitations and design better alternatives for the assets that matter most.
