"Do you know what it means to ask for anything? Vain seeking is wanting to get something for nothing, praying for a windfall from heaven, marrying a rich man, everything going well, and so on. Many times, people always have a misunderstanding, and they want to avoid evil and evil through faith, and when they can't ask for it, they will be discouraged and disappointed when they can't ask for it, and when the situation is not good. Such disappointment is inevitable, because these are all vain requests......" Xu Jingjia said in a serious voice.

Listening to the content of this audio echo in the huge conference room, the message he heard at lunch a few days ago suddenly jumped into Fu Liangtao's mind. Fu Liangtao only felt that the conversation between Xu Jingjia and his friend in the message had a different concept from what Xu Jingjia said in this audio.

Hearing a man who wanted to go to the church to weave a boy say such a thing, Fu Liangtao only felt a little ridiculous.

I saw Luo Mengning press a few times on the tablet, and slowly explained, "These audios were all found in Zhou Muqing's mobile phone backup file. As with the usual procedure, after extracting electronic evidence, the hash value is calculated for each file and then compared with the hash value of the existing electronic evidence.

Just as I told you in advance, after comparison, I found that there were several audio files and image files in Zhou Muqing's mobile phone backup file, which were the same files that were rescued from Li Bingde's laptop."

The hash value is like the ID number of the file, in order to ensure that the electronic evidence has not been modified in the process of analyzing the evidence, the calculation of the hash value for the electronic evidence is basically a specified action before and after the analysis. By comparing the hash values of the electronic evidence before and after it is analyzed, it is possible to know whether the electronic evidence has been altered or destroyed during the analysis.

In addition, since the hash value is equivalent to the ID number of the file, it can also be used to compare whether the electronic evidence from different sources is the same, even if the name and establishment date of the two files are different, the same file can also be found out with the hash value.

"In addition, according to the format of the mobile phone file backup, the model used by Li Bingde before was not a crazy product. This time, I found a Trojan program in Li Bingde's past mobile phone backup file. And the hash value of this Trojan program is exactly the same as the last time I found it in Zhou Muqing's mobile phone. Based on this alone, it can already be determined that the two Trojans are from the same source."

At the same time as Luo Mengning spoke, Fu Liangtao's corner of his eye saw Pang Jitong nodding smugly while listening to this explanation, and glanced at Fu Liangtao provocatively during the period.

The scene yesterday afternoon, Fu Liangtao still remembers it vividly. However, Pang Jitong's strength was only three seconds, and when Pang Jitong felt Fu Liangtao's inaction, Pang Jitong had no confidence. At this moment, Pang Jitong's complacency obviously stemmed from the fact that Luo Mengning's explanation confirmed what he thought.

Fu Liangtao didn't bother to bother with Pang Ji, so he took Luo Mengning's words and said, "Malicious software such as Trojan horse programs will be backed up together with file data and so on when they are backed up. Before and after Li Bingde converted his mobile phone, the system used by the two mobile phones was different, and the Trojan program in the mobile phone had similar functions but also changed.

This shows that Li Bingde's new mobile phone was not infected through the backup files of the mobile phone. It is very likely that Lee Bingde has installed this Trojan horse shell in the old and new mobile phones, and the Trojan horse has become different due to the different mobile phone platforms."

"In this case, the infection process should be related to Li Bingde's habit of using the Internet, or Li Bingde and Zhou Muqing have installed apps that are not from trusted sources." Pang Jitong said.

Fu Liangtao nodded and agreed with Pang Jitong's words, and then turned to Luo Mengning and said, "Is there anything else worth noting in this analysis? If not, I'll talk about the next steps."

"There are two more pieces of audio that I think you want to hear. These two clips may affect the direction of your investigation." Luo Mengning said, seeing that Fu Liangtao and Pang Jitong did not object, she clicked on the audio file she mentioned on the tablet.

Pang Jitong looked at the file names that slid quickly across the tablet screen, and couldn't help but sigh: "There are really a lot of files found in Zhou Muqing's mobile phone backup file this time."

Fu Liangtao could hear that Pang Jitong was speechless, and Zhou Muqing loved to take selfies and use voice messages, which was expected.

"And that's only part of it." Luo Mengning said. "I found quite a lot of files this time, and I filtered them all a little and divided them into folders. And the files in this folder are all related to Xu Jingjia."

Hearing Luo Mengning's words, Fu Liangtao's eyes narrowed.

After a while, I heard Luo Mengning add, "You can believe the details of the file, and after extracting the file, I have done a comparison." Then he said, "All right! Let's get started."

"Zhou Muqing!" Xu Jingjia, who was only listening to the news, screamed with a crying voice. "I've been a friend for so many years, and I only know how to block me with Xu Ningzhi. I'm the only one who is different, am I? …… You two are powerful, the three of us are talking, you two have to discuss it in advance, and then find another messenger after unifying the voice."

After hearing this, Fu Liangtao raised his eyebrows, understanding that it was naturally impossible to say this in front of the parties. This news reminded Fu Liangtao of the calls and messages he had received before.

I only heard Luo Mengning say again, "There is also this paragraph."

"Do you know what books are popular now? The popular one now is "The Theory of Justice", come and see, this is it. You haven't seen it, have you? It's a pity that it's hard to find the original English version now, so if you have the chance, you can look for it." A male voice spoke.

Fu Liangtao and Pang Jitong both recognized this male voice as the male voice who talked about "The Unbearable Lightness of Life".

Next, the two heard Xu Jingjia faintly reply, "I don't understand English." Then the news came to an abrupt end.

Fu Liangtao originally thought that the talk of "The Unbearable Lightness of Life" was just a recording of Li Bingde's lecture on a certain philosophy course, because Xu Jingjia's reaction to Fu Liangtao's temptation was indifferent, and Fu Liangtao was not sure whether that audio was related to Xu Jingjia.

"I didn't find the audio of the philosophical concept in Zhou Muqing's mobile phone file. However, this message seems to have a lot to do with that philosophical message. At the very least, through this recording, we can be sure that the audio of analytic philosophical concepts is also related to Xu Jingjia." Luo Mengning explained.
