The fraudulent prompt claimed users were eligible for a $5,500 token giveaway and asked them to connect their crypto wallets.
🔎 Security update:
Cointelegraph’s banner publishing system was briefly compromised on June 21, resulting in a malicious advertisement promoting a fake token airdrop on our website.
The team identified and resolved the issue by removing unauthorized code that briefly affected

The site warned users not to click the pop-up or share personal information.
On June 20, 2025, our security team identified a vulnerability related to a doodle image displayed on our homepage. This doodle image contained a link that triggered malicious code through an API call, resulting in an unexpected pop-up for some users when visited our homepage.

Cybersecurity firm Hacken faced a $5.5 million loss after a private key leak allowed an attacker to mint nearly 900 million $HAI tokens.
A private key of an account with a minter role (ETH & BNB) was compromised, leading to unauthorized HAI minting and a dump on BSC DEXs.
One big misconception: the deployer wallet was NOT compromised. That’s exactly what let us revoke the compromised minters from the $HAI
— Hacken🇺🇦 (@hackenclub)
6:12 PM • Jun 21, 2025
This overflow in supply caused the token’s value to drop by over 97% on decentralized exchanges.
This incident is a pivotal moment for $HAI.
Our long-term goal: transform $HAI into a regulated financial tool that merges token utility with equity rights.
We are preparing for a big merge between $HAI and Hacken equity shareholders, valued at over $100M.
— Hacken🇺🇦 (@hackenclub)
6:12 PM • Jun 21, 2025
Hacken attributed the breach to "human error" and stated the compromised key came from an account with minting privileges on both Ethereum and BNB networks.
1. Responsibility is on me. I didn't implement multisig bridge ifra 5 years ago. I understood the risk, but delayed bridge restructuring due to not unimportant reasons
2. This incident has nothing to do with the main business. Our experts are the best in the field
3. The most— Dyma Budorin 🇺🇦 (@buda_kyiv)

The attacker only made off with about $250,000, but the market impact was far greater.
Its bridge private key compromise. Worst day
$HAI solo chain design at CEXs allows us to make a snapshot of other chains and make fair compensation
Price drop is the biggest hit in the short term
Not an issue long term

Trezor issued a warning after scammers exploited its website’s support contact form to send phishing emails.
Important Update
We have identified a security issue where attackers abused our contact form to send scam emails appearing as legitimate Trezor support replies.
These scam emails appear legitimate but are a phishing attempt.
Remember, NEVER share your wallet backup — it must
— Trezor (@Trezor)
9:50 AM • Jun 23, 2025
Attackers used the form to generate auto-replies that appeared to be legitimate Trezor support messages.
Here’s what happened
There was no email breach.
Attackers contacted our support on behalf of affected addresses, triggering an auto-reply as a legitimate Trezor support message.
Our contact form remains safe and secure.
We're actively researching ways to prevent future
— Trezor (@Trezor)
10:17 AM • Jun 23, 2025
These emails encouraged users to share sensitive wallet backup information.
Hi, ignore it. Never share your wallet backup (seed) with anyone. No one from Trezor will ever ask for it.
Only enter it into your Trezor device. Never on websites or forms.
Here are some tips to stay safe👇
— Trezor (@Trezor)
10:07 AM • Jun 23, 2025
Trezor assured users that no actual email breach occurred and the form is secure, though addresses may have come from previous leaks.
💡 Feature of the Day:
Self Chain removed its CEO Ravindra Kumar following allegations of his involvement in a $50 million OTC crypto fraud scheme.
Self Chain Governance Update
Due to recent developments that diverge from the founding vision of Self Chain, we are initiating a decisive leadership transition that reinforces our long-term vision.
This marks an important step in realigning Self Chain with its core principles
— Self Chain (@selfchainxyz)
6:04 AM • Jun 23, 2025
The platform announced a “decisive leadership transition” after reports linked Kumar to a Ponzi-style scam using Telegram to sell discounted tokens like GRT, APT, and SUI.
I've been accused of serious wrongdoing, which is completely false. My legal team and I are working on a statement to address this matter. Stay tuned for updates.
— Ravindra Kumar (@ravidsrk)

The scheme lured investors by paying early participants and defaulting on larger promised payouts over time.
Aza Ventures, which facilitated many of the trades, claimed the broker known as “Source 1” turned fraudulent after initially offering real deals.
Glad to see this nonsense properly being busted.
I tried to contact the supposed middleman (Aza Ventures) directly when people were making false accusations about a nonexistent Bera OTC.
He insisted that his sources were good, and wouldn't cooperate with any investigation.

Reports allege that Kumar was this broker, although he denies any connection.
it’s unfortunate victims lost money but why are they doing OTC with a tier 9 fund no one has heard of (zero mutual followers)
also seems multiple teams gave advance warnings (yours, Sui, multiversx)
hard to feel sympathy if you do zero basic due diligence
