The video demonstrates a cyberattack technique where a hacker exploits both system vulnerabilities and human behavior to commit financial fraud.

Instead of stealing large amounts at once, the attacker uses a method where tiny amounts are deducted from a large number of accounts — small enough to go unnoticed individually, but massive when combined.

To gain access, the attack begins with a simple trick: sending a disguised file that appears harmless. Once opened, it allows unauthorized entry into the system.

From there, the attacker moves deeper into the network, eventually gaining control over critical systems and automating the process.

What makes this approach effective isn’t just the technology — it’s the reliance on human error.

One small action can open the door to something much bigger.

00:00The man working at a bank discovered something strange.
00:02He noticed that almost none of the customers withdrawing money ever cared about a one cent
00:05deduction from their accounts.
00:06It was this insignificant service charge that showed Jack the opportunity to get rich.
00:10Because if it worked, he could become wealthy in a single night.
00:13Even though Jack was a humble clerk.
00:14But the bank he worked for had nine, five million customers worldwide.
00:18Depending on the account type, the bank charged service fees almost daily.
00:21If he could take just one cent from each account and keep it, he would quickly become a millionaire.
00:25And no customer would suspect a thing.
00:26But the problem was, Jack was just a regular employee with no system access.
00:30However, he was skilled with computers.
00:32That night, Jack wrote a Trojan program, disguised it as a normal file, and sent it to the bank
00:36president.
00:37Then he quietly waited for the bait to be taken.
00:39Sure enough, the next day, when the president came to work, he habitually turned on his computer.
00:43Seeing what looked like a routine business email, he clicked it without hesitation.
00:47Jack successfully hacked into his computer, and even accidentally discovered his secret
00:51with his young assistant.
00:52But Jack didn't care about that.
00:53He began remote operations, and the Trojan quickly spread through the office, soon infecting
00:58the entire bank system.
00:59His real goal was to locate the administrator's computer, because only that machine had access
01:03to the bank servers.
01:04Soon, employees noticed the system had been compromised, which was part of Jack's plan.
01:08When the cybersecurity staff arrived, the first thing they needed to do was reboot the system,
01:12but that required entering a password.
01:14Jack easily captured the login password and successfully connected to the bank server.
01:17Next, he began deducting one cent from each of the nine, five million customer accounts
01:21under the name of service fees.
01:23In just one minute, he made $95,000 but the money wasn't safe yet.
01:26To avoid leaving evidence, he needed to find a dormant
