🔹 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.

The cross-chain bridge of Orbit Chain was compromised by an exploit, which led to the loss of Tether, DAI, USDC, wBTC, and ETH with a combined value of around $81.4 million.
The vulnerability was exploited by the exploiter, who then transferred funds to a new wallet.
A weakness in the bridge or a hack in the centralized server was discovered as the primary reason by the blockchain security company SlowMist which was responsible for the investigation.
It has been revealed that a hack occurred on Orbit Bridge, which is a protocol for interchain communication that is utilized for asset conversion. A total of around $81.4 million worth of cryptocurrency were stolen from the system.
The Orbit Bridge was struck by a number of significant discharges.
An vulnerability that was worth $81.4 million was apparently used by hackers to ring in the New Year with Orbit Bridge. A number of significant outflows were discovered by the blockchain security company SlowMist and the on-chain intelligence service LookOnChain. These outflows were encountered via the cross-chain protocol.
According to the latter, the Orbit Bridge was responsible for the transfer of 30 million Tether (USDT), 10 million DAI, 10 million USDCoin (USDC), 231 wBTC (worth over $10 million), and 9,500 ETH (worth around $21.5 million) in five distinct transactions.

After doing a preliminary examination from the outside, SlowMist came to the conclusion that either the centralized server has been compromised or there is a potential vulnerability in the Orbit Chain bridge. A further in-depth investigation is currently being carried out by the company in order to obtain additional information on the attack.
The hacking of Orbit Chain has been confirmed.
Orbit Chain reported the hack on its protocol in a tweet that was published not too long ago on X. The tweet described the breach as a "unidentified access" to the bridge. A comprehensive investigation into the underlying cause of the assault is currently being carried out by the company, which has said that it is actively collaborating with law enforcement authorities in order to identify the perpetrator of the incident.
