Hackers use malware files for attack device. They creta malwares and share on Telegram and when anyone download it then hacker got all information about device and then he control device easily and hack wallets and personal information.
Participants in such cryptocurrency forums are primarily the target of such hacker attacks, because if we use such forums and participate in bounty campaigns that are located in them, then we have cryptocurrency wallets on our devices. If earlier hackers hunted for various information, then during the period of growth of cryptocurrency, they also got a good material incentive for their activities. Therefore, we need to be especially careful with our privacy.
