The storm of electronic fraud, the day I was deceived into northern Myanmar

Facing Zhou Yang's problem, I figured it out when I came here.

How to use programming in the park?

Of course it's a scam...

Although this fact is cruel, it is true.

I told him my answer. After listening to it, Zhou Yang said, "You mean, you want to improve your performance through some technical means?"

"almost."

He smiled: "This is simple, social engineering suits your purpose very well."

“What is engineering?”

"Social engineering," Zhou Yang explained, "refers to using some simple technical means to defraud or steal the information you want."

I was a little confused and looked at him with confusion.

He shook his head helplessly, took a laptop from the side, and said: "Programs are made by people. As long as they are made by people, there is no absolute safety, because the biggest weakness is people."

As he spoke, he opened the park's chat software, and then sent a message to someone. The content was: Give me the password for the backend management.

Soon the other party sent a series of numbers.

Zhou Yang looked at me: "Understood?"

I was stunned for a moment, not knowing what he was doing.

He sighed helplessly, pointed to the laptop and said: "Look, this is my account. If you can use my account to send him a message, he can give you the background password. To give a simple example, If you want to get the backend password now, you can't crack it through technical means, but you only need to use my account without me paying attention to get the password. Do you understand now?"

I seemed to understand, so I said, "Does that mean that as long as I get your account, I can get the password?"

"Almost. To put it bluntly, social engineering is not about attacking machines, but about attacking people. Do you understand?"

I thought about it and reacted instantly: "I understand! In other words, if I want to steal information, I just need to find the person who has the information and start with him?"

"clever!"

I asked with some confusion: "Does this have anything to do with computers?"

"It depends on how you understand it."

Zhou Yang opened the QQ software on his computer, and then asked me: "What is your QQ number?"

I told him, and he said, "Okay, you go sit over there and light a cigarette."

I went to the sofa not far away and sat down. I didn't know what he wanted to do.

He took out a cigarette and lit it, then saw him tapping the keyboard continuously.

I smoked slowly, and in about five or six minutes, I finished one cigarette.

It was at this time that he waved me over.

I walked over curiously and found that he had logged into my QQ!

"How do you know my password?"

He grinned: "You guess."

I blinked my eyes and pursed my lips, not knowing what to say.

"Not only do I know your QQ password, I also know that you went to Qingxi Primary School in your hometown for elementary school, and you went to No. [-] Middle School for high school..."

Soon, he revealed a lot of personal information about me!

I swear, I have never told anyone in the park this information. How did he know?

"Are you curious how I know so much about you?"

I nodded.

He said: "It's actually very simple. You only need to learn to use a search engine to find these. I search for your name through the search engine, delete the selections, and then find some relevant information that matches you, and then use the information you left online. Traces, I got your account on the social platform..."

"Through these accounts, I have mastered all your information. After mastering your information, I sorted out all the information related to numbers, and finally came up with your password."

At this point, he paused: "Your password is your initials and birthday plus your student number, right?"

I gasped and nodded.

I have used this password for many years. I always thought it was very safe, but unexpectedly, it took just one cigarette to crack it!

The problem is, he didn't use any so-called hacking techniques.

I thought about it and said, "I have a question..."

"You ask."

"You said you got my information through a search engine, but there are so many people named Yang Lei, and I rarely reveal my real name online, how could you possibly find it?"

He smiled and gave me his laptop: "How do you usually use search engines?"

I took the computer and put it on the table, then typed my name in the search box and clicked the Enter key: "This is how I usually use it..."

“That’s the difference between ordinary people and professionals.”

As he spoke, he turned the computer over, entered a string of characters into the search box, and finally entered my name.

After pressing the Enter key, the message that I quickly pinned to the top was exactly what I posted on the campus website back then.

The content of the post was that I asked for the contact information of the guitar club, and I left my class and real name in it!

"What is that string of things you entered?" I couldn't help but ask.

"This is called a signature. As long as you learn to use these signatures, you can find anything you want through the search engine."

He said: "Anyone who frequently surfs the Internet will leave traces of himself on the Internet, and these traces will accumulate more and more. Through these traces, you can quickly collect all the information about him."

"The simplest way is that when searching for something, if there are more than two keywords, you use the plus sign to concatenate them, and the minus sign is to exclude filtered keywords, and double quotes are to search for complete sentences..."

He gave me many examples about the use of search engines, such as the use of "OR".

For example, if I want to search for one of the keywords "Yang Lei" and "Zhou Yang", I can use "OR" to connect them in series, and finally it becomes: Yang Lei OR Zhou Yang.

He also told me that the key word he used to find my school was: filetype:xlsinurl:gov student list.

He also told me that if I want to find something like a table, I just need to enter: filetypexls to search for content.

For example: filetypexls ID number.

……

"I will compile some information on how to use search engines and send it to you later. You can study it carefully later." Zhou Yang said with a smile.

I nodded: "Thank you very much."

"No need to thank you. I've answered more than ten of your questions today, right?" He smiled and said, "Forget it, I'll just give you a discount and charge you [-]. The information you want is five thousand."

Without saying anything, I took out the [-] yuan in chips and handed them over: "These are all for you."

He raised his eyebrows and took it directly without being polite to me.
