🚨$70M GONE IN 41 MINUTES - no hack, no phishing, no physical access.
Nearly 1,200 COLDCARDS wallets drained. The attacker never touched a device or stole a seed phrase. The reverse-engineered predictable randomness in flawed firmware (Mk2-Mk5, Q) to recreate private keys offline. Pure math, zero contact.
This is your reminder: NEVER hold 100% of your stack in one wallet or one brand. Hardware wallets aren't infallible, diversify across devices, use multi-sig, split your cold storage. One flaw = total loss.
If you're on affected Coldcard firmware, migrate NOW.
Not your keys, not your coins. But also: not your diversification, not your safety.🔐

🚨 LATEST UPDATE 🚨
The scope of the Coldcard wallet security incident has expanded significantly. New analysis from Galaxy Research indicates that approximately 1,082.65 Bitcoin—valued at roughly $70.2 million—was moved through 1,196 different addresses during a brief 41-minute window on July 30.
This scale of loss is much higher than earlier estimates of $38 million. The attack followed a specific pattern of identical transaction fees and no change outputs. Coinkite co-founder Rodolfo Novak has acknowledged a firmware bug and released a hotfix, but warned that users with seeds generated on the vulnerable firmware should move their funds to a new seed immediately to ensure safety. 🛡️
This development highlights the critical importance of hardware wallet security and firmware integrity for self-custody. 🔐

A critical firmware vulnerability in Coldcard Mk3 hardware wallets (and potentially later models) allowed attackers to exploit weak entropy in seed generation. The exploit drained 1,082 BTC worth around $70 million from 1,196 addresses in just 41 minutes — 30 hours before Coinkite issued a public warning.
This marks the third-largest crypto hack of 2026 and has raised fresh concerns over self-custody security, while also adding selling pressure on Bitcoin. Users with affected devices should take immediate precautions. DYOR.

🚨 CZ Calls for Wallet Diversification After $70M Coldcard Exploit 🚨
Binance founder Changpeng Zhao (CZ) is urging crypto users to spread their funds across multiple wallets following a major $70 million security failure impacting Coldcard hardware devices.
CZ emphasized that even hardware wallets are not immune to bugs and vulnerabilities. To mitigate risks, he suggests a diversification strategy rather than relying on a single security solution.
Key Takeaways:
🔒 Hardware wallets can still have software flaws.
💸 Spreading funds reduces single-point-of-failure risks.
🛡️ Diversification is vital for long-term asset security.
So what is actually happened and what we need to do with it?
Do not worry, if you are not using Coldcard wallet, you are worry free.
The reported COLDCARD vulnerability stems from a critical firmware bug that disabled the hardware random number generator. This flaw allows attackers to replicate recovery seeds generated on affected devices and steal funds.
Crucially, a simple firmware update will not secure vulnerable accounts. Affected users must immediately generate an entirely new recovery seed on patched firmware and transfer their BTC to the new address.
🚨 Critical Security Steps Required
1) Update firmware to the latest patched version immediately.
2) Generate a new seed phrase directly on the secure firmware.
3) Transfer all BTC from the compromised setup to the new wallet.
4) Never reuse the old, vulnerable recovery seed phrase.

"HOLD UP, Bitcoin fam, looks like the Coldcard thief was basically "funding their habits" with the top blockchain service provider's help. #Coldcard #BlockchainSecurity
THE ALPHA
It turns out, the Coldcard thief didn't even need to "hodl" the secret to their success - they used a top blockchain service to facilitate the hack. Bitcoin holders with Coldcards are advised to move funds ASAP. #BlockchainServices
THE PUNCHLINE INSIGHT
Guess who's got a hot new wallet on their Christmas list? That's right, Bitcoin holders who want to keep their coins safe from rogue 'services' should probably consider a hardware wallet that doesn't rely on being online 24/7.
ENGAGEMENT BAIT
Are you still HODLing on a Coldcard? Better start thinking about an exit strategy..."

Guys...... big news.
Coldcard had a bug.
It made some wallet keys easy to guess.
Hackers took about 594 BTC fast.
Maybe more, close to 1,080 BTC total now.
That's real money gone.
From wallets people thought were 100% safe.
BTC price barely moved though.
Market did not care.
But u should care.
If u use Coldcard, update ur firmware now.
Don't wait.
Move to a new seed after update.
Old one might not be safe anymore.
Lesson here...... "cold wallet" does not mean "no risk" wallet.
Always double check. Always update.
what do u think, does this scare u or not really?

Coinkite is advising Coldcard Mk3 users to migrate funds following a potential seed-generation risk. Additionally, security experts are investigating a massive $38 million Bitcoin wallet drain.
#CryptoSecurity #Coldcard
#CryptoSecurity #Coldcard
This firmware vulnerability from Coldcard is indeed a rare and serious incident in the hardware wallet field.
On July 30, attackers exploited a flaw in the random number generation process during seed creation and swept away a large amount of $BTC within about 40 minutes.
Initial confirmation put the amount at approximately 594 BTC (about $38 million at the time), coming from about 500 addresses; subsequent on-chain analysis by Galaxy Research expanded the scale to 1,082.65 BTC (about $70 million), involving 1,196 addresses.
The root cause lies in certain firmware versions after March 2021: when the device generated the seed, it failed to correctly call the hardware true random number generator, causing the entropy to drop significantly (about 40 bits on Mk3), allowing the private key to be reconstructed offline. The entire attack required no interaction with a physical device.
The official side has released a fixed firmware, but already-generated weak seeds cannot be repaired via an update. Affected users must regenerate new seeds and migrate funds as soon as possible.
CZ also publicly reminded: even hardware wallets may have vulnerabilities—risk has always existed, and there is no 100% security on-chain.
Based on the scope of impact and the technical nature, this is the largest known hardware wallet firmware vulnerability attack to date, and it has dealt a significant blow to trust in self-custody security. In normal times, it’s still recommended to pay close attention to official security advisories and avoid concentrating all assets in a single device.
