The attackers schedule meetings through Calendly, send seemingly normal "Zoom links," trick victims into installing fake Trojans, and even gain remote control of the computer during the meeting. Overnight, wallets and Telegram accounts were completely seized. This article will comprehensively analyze the operation chain and defense points of such attacks, and attach complete reference materials for community forwarding, internal training, or self-inspection. The dual goal of attackers Stealing digital assets: Using malicious programs such as Lumma Stealer, RedLine or IcedID, directly stealing private keys and mnemonics in browsers or desktop wallets, and quickly transferring cryptocurrencies such as TON and BTC. Stealing identity credentials: Stealing Telegram, Google's Session cookies, pretending to be victims to continue to contact more objects, forming a snowball spread. Four Steps to the Attack Chain (1) Build trust Impersonate investors, media, or podcast hosts and send official meeting invitations through Calendly. For example, in the case of "ELUSIVE COMET", the attacker disguised the Bloomberg Crypto page for phishing. (2) Dropping Trojans Fake Zoom links (not .zoom.us endings) to direct users to download a malicious version of the ZoomInstaller.exe. Several incidents in 2023–2025 were planted in this way with IcedID or Lumma Trojans. (3) Power seizure in the meeting The hacker changed the nickname to "Zoom" in the Zoom meeting, asked the victim to "test the shared screen", and transmitted the remote control request at the same time. Once "Allow" is clicked, the unit is completely taken over. (4) Proliferation and cash-out The malicious program will immediately withdraw coins after uploading the private key, or lurk for several days and then pretend to be Telegram identity to continue phishing others. RedLine develops targeting features specifically for Telegram's tdata directory. Three steps to first aid immediately isolate the device: unplug the network cable, turn off the Wi-Fi, boot the device with a clean USB and scan it completely; If RedLine/Lumma is found, it is recommended to format the reirrigation system completely. Undo all Sessions: transfer crypto assets to a new hardware wallet; Telegram logs out all devices and enables two-step verification; Change all passwords such as email address, exchange, etc. Synchronous monitoring of on-chain and exchange dynamics: When suspicious transfers are found, contact the exchange immediately to request the freezing of relevant addresses. The Six Iron Laws of Long-term Defense Independent conference device: Strange meetings only use a spare laptop or mobile phone without a private key. Download software only from the official website: Tools such as Zoom and AnyDesk must be downloaded from the official website macOS It is recommended to turn off the "automatically open after downloading" function. Strictly check the URL: the meeting link must end in .zoom.us; The Zoom Vanity URL must also conform to the specification. Three no's principle: do not install plug-ins, do not give remote, do not display mnemonics or private keys. Hot and cold wallet separation: the main asset uses a cold wallet and sets a PIN and Passphrase; Hot wallets only keep small amounts of funds. Enable 2FA for all accounts: Telegram, email, GitHub, exchanges, etc. all enable two-factor authentication. Conclusion: The Real Risk of Fake Meetings Modern hackers don't rely on 0-day vulnerabilities, but are good at acting. They design Zoom meetings that "look normal" and wait for you to make a mistake. As long as you develop good habits: isolation devices, downloading only from the official website, multi-factor authentication, this type of attack is very difficult to succeed. May every on-chain user stay away from the trap of social engineering and keep their own vault and identity.
