New crypto wallet clipper targets Portuguese speakers
There are various techniques for crypto theft, and one approach involves detecting when a Bitcoin address is copied to a clipboard and quickly replaced with a different address belonging to the threat actor. This is to trick users into sending Bitcoins to the wrong address. This method is highly effective because Bitcoin transactions are irreversible.
A malware campaign using the above technique has been observed in the wild targeting victims from multiple industries, including IT, real estate, and manufacturing.

New malvertising campaign spreads Atomic Stealer (AMOS) to macOS users
Atomic macOS Stealer (aka AMOS) has been discovered around April 2023. The malware steals a wide range of sensitive data from infected machines, including system information, keychain passwords, user documents, cookies, browser data, credit card details, cryptocurrency wallets, and others. A new malvertising campaign spreading this malware variant has been recently observed in the wild. The attackers have been masquerading their malicious download website as TradingView which is a popular charting platform and social network used by traders and investors. The malicious page offers downloads of a fake TrandingView desktop app for multiple platforms. While the Windows and Linux variants app would lead to download of NetSupport RAT, the macOS version results in Atomic Stealer installation on the victim machine.
