🔹 Fake Zoom meeting invites and update links deceive Web3 teams

🔹 New NimDoor malware infiltrates macOS with advanced evasion techniques

🔹 Attackers steal browser data, passwords, and Telegram chats

Web3 and Crypto Companies Under Siege by NimDoor Malware
Security experts at SentinelLabs have uncovered a sophisticated malware campaign targeting Web3 startups and cryptocurrency firms. The attacks, linked to North Korean groups, use a combination of social engineering and technical stealth to deploy NimDoor malware, written in the rarely used Nim programming language to bypass antivirus detection.

The Setup: Fake Zoom Meetings Through Telegram
Hackers initiate contact via Telegram, posing as known contacts. They invite victims to schedule meetings via Calendly, then send them links to what appear to be Zoom software updates. These links lead to fake domains like support.us05web-zoom.cloud, mimicking Zoom's legitimate URLs and hosting malicious installation files.
These files contain thousands of lines of whitespace, making them appear "legitimately large." Hidden within are only three crucial lines of code, which download and execute the real attack payload.

NimDoor Malware: Spyware Specifically Targeting macOS
Once executed, the NimDoor malware operates in two main phases:
🔹 Data extraction – stealing saved passwords, browsing histories, and login credentials from popular browsers like Chrome, Firefox, Brave, Edge, and Arc.

🔹 System persistence – maintaining long-term access through stealth background processes and disguised system files.
A key component specifically targets Telegram, stealing encrypted chat databases and decryption keys, giving attackers access to private conversations offline.

Built to Survive: Evasion and Reinstallation Techniques
NimDoor employs a range of advanced persistence mechanisms:
🔹 Automatically reinstalls itself if users try to terminate or delete it

🔹 Creates hidden files and folders that look like legitimate macOS system components

🔹 Connects to the attacker’s server every 30 seconds for instructions, disguised as normal internet traffic

🔹 Delays execution for 10 minutes to avoid early detection by security software

Difficult to Remove Without Professional Tools
Because of these techniques, NimDoor is extremely hard to remove with standard tools. Specialized security software or professional intervention is often required to clean infected systems completely.

Conclusion: Modern Cyberattacks Now Look Like Calendar Invites
Attacks like NimDoor prove how cleverly North Korean groups mimic daily workflows to penetrate even cautious targets. Fake Zoom links and innocent-looking updates can lead to full system compromise.
Users should never download updates from unofficial sources, always verify domain names, and stay vigilant against unexpected software prompts or invitations.

On February 21, 2025. Bybit Exchange, a prominent cryptocurrency exchange, experienced a significant security breach resulting in the unauthorized transfer of approximately $1.46 billion worth of assets. The incident involved the compromise of Bybit's Ethereum (ETH) cold wallet, leading to the loss of 401,346 ETH (approximately $1.1 billion) and various staked Ether (stETH) tokens. The perpetrator has been liquidating these assets on decentralized exchanges.
Bybit's CEO, Ben Zhou, confirmed the breach, explaining that a planned transfer was manipulated, allowing the attacker to gain control over the specific ETH cold wallet. Zhou assured users that all other cold wallets remain secure and that withdrawals are functioning normally.
This event marks one of the largest cryptocurrency hacks to date, surpassing previous incidents such as the Mt. Gox hack ($470 million), the CoinCheck hack in 2018 ($530 million), and the Ronin Bridge exploit ($650 million).
In response to the breach, major cryptocurrencies experienced price declines. Ethereum's price fell nearly 3% to approximately $2,727, while Bitcoin dipped by nearly 1% to around $98,091.
Users are advised to monitor their accounts closely and exercise caution with their assets during this period.
