Sun shared the analysis on his Twitter account, revealing how simple it is to be hacked and how attackers are stealing info like wallet data and Discord session tokens to gain access to users’ cryptocurrencies. In the case of Sun, a malicious actor sent a message with a link to arouse his curiosity.
The message read,
I am sorry to disappoint you.
You are being sued.
You can read a copy of the lawsuit here (Malicious link)
No copyright has been claimed.
You can also write a statement in response, good evening John.
Sun revealed that messages accompanied by malicious links are compelling hooks and when placed under pressure, even trained security professionals might act irrationally and click on the link.
Clicking the link downloads a file to the target’s computer. This is the first step, opening the downloaded file takes the target another step closer to getting hacked. Once the file is opened, the attacker has access to wallet data, browser extensions or Discord session tokens of the target. This gives the malicious actor direct access to your cryptocurrency.
“Hybrid Analysis”, an automated malware analysis service provider, helped Sun identify that the two downloaded files on his device were malicious. Running the files through a malware analysis detector helped him determine that the attacker attempted to steal his cryptocurrency. Therefore, Sun warns his followers against running downloaded programs, files without running them through malware analysis detector.

Attacks are therefore not limited to the DeFi ecosystem, and cryptocurrency holders are simply three clicks away from losing access to their holdings.
