Transmigrated into Conan, his ability is Rhodes Island

"Oh my, senior!" The cheerful and outgoing college student, Akihara Kazuhiro, put down the documents he was organizing and greeted the passing senior with a smile.

The other person greeted him politely and then scurried away. Watching the other person's departing figure, Akihara Kazumitsu sighed inwardly and continued with his work.

After returning from Shinjuku, he had run out of money and was now struggling to even afford food. Akihara then tactfully explained his situation to his advisor, Professor Hirota, who expressed great sympathy and recommended him for book and document organization work at the library.

In the end, I still ended up living the life of a high-earning employee... My heart aches so much, I want to go back to Rhodes Island... I want to cry but I can't, but I still have to smile on my face.

In a fit of anger, she shoved the last book she needed to organize onto the bookshelf, but as she looked up, she caught a glimpse of Akemi Miyano walking by with a book in her hand.

"Ah, good morning, Miyano-senpai!" It wasn't even nine o'clock yet, and the library hadn't officially opened to the public, so there was almost no one inside. Akihara felt at ease and greeted Miyano Akemi in a normal voice.

Miyano Akemi was walking briskly forward, looking preoccupied, and hadn't noticed Akihara Kazuhiro, who looked like a librarian, until Akihara greeted her. Suddenly, she was startled by someone calling her name and instinctively turned around to look around. When she saw that the person who called her was Akihara Kazuhiro, a junior she had just met last week, the worry on her face faded and was quickly replaced by a smile.

"Good morning, Akihara-kun. So you've been helping out here."

Akihara responded with a slightly embarrassed smile, "Ah... that's right, my family isn't well-off, but thankfully Professor Hirota introduced me to a work-study program."

System: How can someone lie without even thinking it through!

Akemi Miyano looked surprised. "Oh, is that so? I didn't know... By the way, my friend opened a coffee shop and is hiring temporary workers. You can give it a try if you need any."

A coffee shop... Will I have a similar character to Amuro Tooru? He thought to himself, but remained outwardly calm. "Okay, okay, thank you, senpai."

Akemi Miyano tore off a piece of paper, wrote down the exact location of the café, and handed it to Akihara, who thanked her and accepted it.

After carefully putting the note into his pocket, Akihara seemed to only then notice it, and he asked hesitantly, "By the way, Miyano-senpai, I noticed you weren't very happy just now. Is there anything I can do to help you?"

This time, Miyano Akemi was genuinely taken aback. "Was I that obvious...?" she instinctively tried to brush it off. Miyano Akemi lowered her head, avoiding eye contact, and after a moment, she looked back at Akihara with an apologetic smile. "Thank you for your concern, Akihara-kun. It's like this, a friend of mine—ah, not the one who owns the coffee shop—Katsuya Mitsue, is organizing a mixer, but they don't have enough people, so they require me to invite one person..."

"Oh, I see." Akihara Kazumitsu pretended to believe her, but inwardly he thought this girl really couldn't lie. Akihara was just guessing whether Miyano Akemi's troubles stemmed from Akai Shuichi trying to extort money from her. But there was no way to verify it at the moment.

"Ah." At this point, Miyano Akemi looked at Akihara Kazumitsu, a sudden realization dawning on her face. "Akihara-kun, could I invite you to a mixer?"

Wow, a chance to earn points! Great!

"Oh, really? Thank you, senior." Akihara looked pleasantly surprised, then added self-deprecatingly, "The professor always complains that I don't know how to socialize, now I have something to say back to him."

Akemi Miyano was amused. Afterwards, Akemi Miyano told Kazuhiro Akihara the address and time of the matchmaking event. The two said goodbye to each other, and as Akemi Miyano's figure gradually disappeared into the distance, Kazuhiro Akihara pushed the library's book-organizing cart back to report.

The system spoke softly in his mind: "No way, you're not planning to go on a blind date like this, are you? You're penniless right now, you don't want the girls to pay for your share, do you?"

Akihara:……

He would never admit that he had completely forgotten about this in order to get closer to Akemi Miyano.

"Ahem, I have a brilliant plan," Akihara Kazumitsu replied, feigning mystery.

……

"What are you doing?! (ノ=Д=)ノ┻━┻ Why are you starting to act recklessly again without warning?" the system lamented. "I knew you were reckless, but I didn't expect you to be this reckless!"

"Quiet down, I had no choice but to do this, just to make quick money," Akihara Kazumitsu replied, his hands continuing to type on the keyboard.

He also remembered that in the original work, the email address of the Black Organization boss was a syllable of a children's song. He used WHOIS to look up the registered domain of the email address, and then used some social engineering methods to determine the Black Organization's internal network domain. After some effort, he used an internal network penetration tool to enter the organization's internal network with a virtual IP address.

Of course, since we're accessing the client side now, we can't retrieve information from the organization's servers. However, Akihara found that current cybersecurity awareness is really lacking; he casually tested a few common web security vulnerabilities, and it seemed there were no corresponding defenses.

What kind of organization's internal network is this? It's practically the perfect training ground for web penetration testers.

The personnel login interface lacked a security verification code; there was no judgment or restriction on login attempts, and multiple failed login attempts did not lock the account or IP address; the data from the front end was not strictly judged when it was sent to the back end for processing... Qiu Yuan's face twitched more and more as he looked at it. How could the organization outwit the Red Team with such a low level of security? Although the main storyline had not yet started, there was still plenty of time to upgrade the internal network. It didn't matter who made the money, so he might as well keep it for himself.

He opened a document and began writing improvement suggestions while taking screenshots. For example, the current SQL injection vulnerability, as a common and extremely dangerous cybersecurity vulnerability, is a top priority for improvement. Without proper validation of user input, malicious users can inject malicious SQL code into input fields, leading to data tampering or leakage in the database.

For example now——

On the website's login page, Akihara Kazumitsu clicked on the username input box and wrote down a line of SQL code.

A normal SQL query might look like this: "SELECT * FROM users WHERE username='entered username' AND password='entered password';"

However, Akihara Kazuhiro entered "OR 1=1 --" in the username field. The logic is easy to understand: the login process can be viewed as a system checking if the username and password are correct. Now, the field has become an arbitrary password or "1=1". Since "1=1" is always true, this statement will be correct regardless of how it's checked, and the system will allow it. Here, "--" is a comment symbol in SQL; everything after it will be ignored.

This allowed Akihara Kazumitsu to bypass authentication and log into the organization's intranet. He could also modify the injection statements to obtain more information about the organization. Akihara Kazumitsu had no immediate intention of antagonizing Gin, so he did not launch any further attacks.

In the document, Akihara Kazumitsu briefly explained the principle of the vulnerability, and then added the following:

"To prevent SQL injection vulnerabilities, developers should effectively validate and filter user input. The most common defense method is to use parameterized queries or prepared queries to avoid including user input as part of the SQL query."

After listing dozens of vulnerabilities, Akihara finally breathed a sigh of relief and packed the document into a disk.

Stretching, Akihara took out his phone and dialed Gin's number.
