In the early hours, the Origin Awakening World resembled an abandoned electronic city. The bustling virtual marketplace that thrived during the day was now deserted, with towering digital buildings casting a cold glow in the night. Occasionally, a few players who had been online for hours drifted by, their heads adorned with the tag [Online 72 Hours], wandering like ghosts.
I logged in from a secluded corner of a server node, a habit ingrained from my profession as a Security Engineer. Pulling up Li Wei's account data, familiar code flowed before my eyes. The hacker cases I had dealt with before were either phishing trojans or brute-force attacks. But this time was different; the opponent had achieved a Perfect Clone within the blockchain's "immutable" system, a technique unsettlingly sophisticated.
As I analyzed the anomalous code, a private message notification suddenly lit up.
A stranger ID: "Phantom," noted that this account had only been registered for three days.
"I heard that DCT's Engineer Gao is investigating recent theft cases?" they got straight to the point.
Interesting—was this a hacker's probe or a hint from someone in the know? Clearly, my investigation had caught someone's attention. I cautiously replied, "You seem well-informed about this matter?"
"8 PM the day after tomorrow, at the Paradise Space club." The other party sent a string of coordinates. "Maybe you'll find the answers you seek. Remember, don't bring any tracking devices."
Just as the message was sent, Phantom's avatar went dark. I tried to trace back the history but found it completely blank; even the login IP showed as "unknown." This ability to erase all traces was something I had only seen in internal training at the Cybersecurity Bureau. Phantom's background was likely significant.
I pulled up the map of Origin Awakening World and searched for Paradise Space. This club had only gone live two days ago and was extravagantly decorated; just getting in required 50,000 virtual coins. More intriguingly, the developer, Future Vision Technology, had registered exactly when the press conference took place three months ago.
Just as I was about to delve deeper into my search, Li Wei's WeChat message popped up:
"Fei Ge, I found something. It seems that all those victims received an airdrop gift from Future Vision Technology." He sent over several screenshots. "It's a limited edition NFT skin, said to be a commemorative item from the press conference. At that time, everyone thought they struck gold; but once installed, it automatically integrated into their systems."
A cold sweat broke out on my back. On the surface, an NFT skin seemed like a simple decoration; however, if it contained a Backdoor Program and was combined with user information collected during the press conference, it could easily bypass the blockchain's security mechanisms. The hacker's methods were more sophisticated than I had imagined; they had laid their traps deep within the system's foundation.
I pulled up the code analyzer and began to inspect the NFT's program line by line. The characters on the screen blurred, straining my eyes, but experience told me there had to be something wrong. Ordinary NFTs have a small amount of code, mainly for decorative functions. However, this skin's code was absurdly lengthy, totaling over 500 lines, with extensive obfuscation added. A typical Security Scan would never uncover the hidden tricks within.
As dawn approached, I finally found a breakthrough. Line 389 concealed a cleverly disguised function call, masked by multiple layers of encryption. This piece of code would automatically activate at a specific time, silently altering the user's authentication information.
"Impressive," I muttered, rubbing my aching eyes. Such a covert backdoor technique was not something an ordinary hacker could design. The other party was a well-trained team; they had used the launch event to deploy a Trojan and were now ready to reel in their catch.
Suddenly, I recalled the announcement about the upcoming update for Origin Awakening World—the timing perfectly aligned with the trigger for this Backdoor Program. It seemed that a meticulously planned digital storm was about to unfold.
