do you happen to know which facial expression is the “autizm” one from classic hd? i cannot stop thinking about this lately of all things they could have called it they went for “autizm”. thanks in advance! :)

Thanks for sending me on this quest! It's been a few years since the discovery of Autizm, and in this time the Pathologic community has developed advanced tools for its analysis. Namely, Gorkhon Script Editor allows the viewing of bytecode scripts, which are where LifeStudio:HEAD facial animations are controlled. With GSE, pathologicdialogue, and somevideoguy's string unpacker, I was at last able to find dialogue lines that, with 100% certainty, cause the Autizm facial expression for each character.

For Grace and Murky, Autizm is a pretty similar expression: they look directly forward. Grace stays still, while Murky raises and lowers her head slightly. However, Grace's Autizm is distinguished by being on a 15-second loop (Murky's and Peter's both last 10 seconds.)

On the other hand, Peter's Autizm expression has almost no eye contact - he looks away and up, occasionally glancing at the player.

There's more to discuss about the process of tracking these down... I'm tempted to do a quick video about it in the near future, schedule permitting. (Look under the cut for the example dialogue lines that you can find to see Autizm for yourself.) In conclusion,

Grace: bachelor day 2 - I don't know. The dead told me to remind you that you will be spoken for by those whom you save, that's all. Is it true that you're going to leave us soon? (509475) [no requirements]

Murky: bachelor day 6 - The mara's hiding today. Everyone's hunting her. And she's hunting you. She thinks that if she kills you, everyone will just let her go. Tee-hee... (512811) [requires that Grace has told you to ask Murky where Clara is to draw her blood]

Peter: bachelor day 2 - Can't you see what I've managed to build here? Where else would I be allowed to do something like this? Everything that I have ever called my purpose has been brought to life in this town. For now, I have no reason to leave it. I haven't finished my observations yet. I'm this close to figuring it out... (507443) [requires Andrey to have agreed to flee the town]

Introduction to JavaScript Compilers

JavaScript is one of the most widely used programming languages, powering web applications, servers, and even mobile apps. But how does JavaScript code transform from human-readable text into executable instructions? The answer lies in the JavaScript compiler.

A JavaScript compiler translates high-level JavaScript code into optimized machine code or bytecode, improving performance and efficiency. In this article, we’ll explore how JavaScript compilers work, their key components, and their role in modern web development.

What Is a JavaScript Compiler?

A compiler is a software tool that converts source code written in a high-level programming language (like JavaScript) into a lower-level representation (such as machine code or bytecode). Unlike interpreters, which execute code line by line, compilers process the entire codebase at once, optimizing it for better performance.

JavaScript engines like V8 (Chrome), SpiderMonkey (Firefox), and JavaScriptCore (Safari) use Just-In-Time (JIT) compilation to execute JavaScript efficiently.

How Does a JavaScript Compiler Work?

The JavaScript compilation process involves several stages:

1. Parsing (Lexical Analysis & Syntax Tree Generation)

The compiler first breaks down the code into tokens (keywords, variables, operators).

It then constructs an Abstract Syntax Tree (AST), a structured representation of the code’s logic.

2. Compilation (Bytecode or Machine Code Generation)

Modern JavaScript engines use JIT compilation, which combines interpretation and compilation.

The engine converts the AST into bytecode (an intermediate low-level code) or directly into machine code for execution.

3. Optimization (Inlining, Dead Code Elimination, etc.)

The compiler applies optimizations like:

Inline Caching: Speeds up property access.

Hidden Classes: Optimizes object property access.

Dead Code Elimination: Removes unused code.

4. Execution

The optimized code runs in the browser or Node.js environment.

R Compiler vs. Interpreter

In programming languages, a compiler translates the entire source code into machine code before execution, making programs run faster, while an interpreter executes code line by line, allowing real-time feedback but often at the cost of speed.

Understanding Compilation and Interpretation

Compiler:

Interpreter:

How R Works: Interpreter vs. Compiler

R is primarily an interpreted language, meaning that when a command is entered, it is executed immediately without requiring prior compilation. This makes it highly suitable for data analysis, statistical computing, and visualization, where real-time feedback is essential.

However, R also has Just-In-Time (JIT) Compilation, which allows parts of the code (such as functions and loops) to be compiled into bytecode before execution. This improves performance while retaining the flexibility of an interpreted language.

Conclusion

While R remains an interpreted language in most cases, its support for JIT compilation through the compiler package helps optimize performance where needed. This hybrid approach allows R to maintain its interactivity while benefiting from compilation efficiency in performance-intensive applications.

In It has become commonplace in software engineering to refer to testing in a shift-left fashion in recent years. How does that work? This refers to conducting more software testing during the software development phase to reduce defects and save the business money.

The term shift-left testing refers to increased involvement by quality assurance (QA) engineers during the development phase to detect bugs as early as possible, before software engineers have handed the code over to QA for further testing. The most common method is to develop and execute more automated testing of the UIs and APIs.

A software developer should, however, perform a few basic and essential software testing steps before showing someone else their work, whether it is for shift-left testing, formal testing, ad hoc testing, code merging and integration, or just calling a colleague over for a quick look. Its goal is to detect obvious errors that jump out immediately during this basic testing. You would otherwise have to describe the problem to the developer, who would then have to reproduce, debug, and solve it before trying again.

Each software engineer should perform these essential software testing steps before showing their work to others.

1. Basic functionality testing Begin by making sure that every button on every screen works. You also need to ensure that you can enter simple text into each field without crashing the software. You don't have to try out all the different combinations of clicks and characters, or edge conditions, because that's what your testers do—and they're really good at that. The goal here is this: don't let other people touch your work if it's going to crash as soon as they enter their own name into the username field. If the feature is designed to be accessed by way of an API, you need to run tests to make sure that the basic API functionality works before submitting it for more intensive testing. If your basic functionality testing detects something that doesn't work, that's fine. Just tell them that it doesn't work, that you're aware of it, and that they shouldn't bother trying it. You can fix it later, just don't leave any surprises in there.

2. Code review One more sets of eyes taking a gander at the source code can reveal a great deal of issues. Assuming that your coding system requires peer audit, play out this step before you hand the code over for testing. However, make sure to do your essential usefulness testing before the code survey.

3. Static code analysis There are devices that can perform investigation on source code or bytecode without executing it. These static code examination apparatuses can search for some shortcomings in the source code, for example, security weaknesses and potential simultaneousness issues. Utilize static code examination apparatuses to implement coding guidelines, and arrange those devices to run naturally as a feature of the form.

4. Unit testing Engineers will compose unit tests to ensure that the unit (be it a technique, class, or part) is filling in true to form and test across a scope of substantial and invalid data sources. In a consistent reconciliation climate, unit tests ought to run each time you commit a change to the source code store, and you ought to run them on your improvement machine too. A few groups have inclusion objectives for their unit tests and will bomb a form on the off chance that the unit tests aren't sufficiently broad.

Engineers likewise work with mock articles and virtualized administrations to ensure their units can be tried freely. Assuming your unit tests fall flat, fix them prior to letting another person utilize your code. If under any circumstance you can't fix them at this moment, let the other individual in on what has fizzled, so it won't come as a shock when they run over the issue.

5. Single-client execution testing A few groups have burden and execution testing heated into their ceaseless mix cycle and run load tests when code is checked in. This is especially valid for back-end code. In any case, designers ought to likewise be taking a gander at single-client execution toward the front and ensuring the product is responsive when they are just utilizing the framework. On the off chance that it requires in excess of a couple of moments to show a site page taken from a neighborhood or copied (and in this manner responsive) web server, figure out what client-side code is pumping the brakes and fix it before you let another person see it.

UNC5812: Russian Group “Civil Defense” Malware Campaign

Russian Hybrid Espionage and Influence Campaign Seek to Deliver Anti-Mobilization Narratives and Compromised Ukrainian Military Recruits

In September 2024, the Google Threat Intelligence Group which is made up of Mandiant and Google’s Threat Analysis Group (TAG) discovered UNC5812, a suspected Russian hybrid espionage and influence campaign that used the Telegram persona “Civil Defense” to distribute malware for Windows and Android. According to their claims, “Civil Defense” offers free software applications that let prospective conscripts see and share crowdsourced locations of Ukrainian military recruiters.

These apps provide the victim with a decoy mapping application it track as SUNSPINNER combined with an OS system-specific commodity malware version if they are installed with Google Play Protect turned off. UNC5812 is actively involved in influence activity, disseminating narratives, and requesting content aimed at undermining support for Ukraine’s mobilization efforts, in addition to using its website and Telegram channel to distribute malware.

Targeting Telegram Users

Both the website civildefense[.]com.ua and the actor-controlled Telegram channel @civildefense_com_ua are used by UNC5812 to distribute malware. In April 2024, the related website was registered; however, the Telegram channel was not established until early September 2024, which it believes marks the full operationalization of UNC5812’s campaign. It estimates that UNC5812 is probably buying promoted posts in reputable, well-established Ukrainian-language Telegram channels to direct potential victims to these actor-controlled sites.

A reputable missile alerts Telegram channel with over 80,000 followers was seen advertising the “Civil Defense” website and channel to its members on September 18, 2024.

As recently as October 8th, another Ukrainian-language news outlet promoted Civil Defense’s articles, suggesting the campaign is likely still actively looking for new Ukrainian-language groups for focused interaction.

Channels that have pushed “Civil Defense” posts highlight the opportunity to contact their administrations about sponsorship opportunities. It believes that to expand the operation’s scope, UNC5812 is most likely approaching the appropriate legal channels through this vector.

The campaign’s ultimate goal is to direct victims to the “Civil Defense” website, which is under UNC5812’s control and promotes a number of software applications for various operating systems. These apps download different commodity malware families when they are installed.

The website provides a PHP downloader for Windows users called Pronsis Loader, which is publicly recorded and compiled into Java Virtual Machine (JVM) bytecode using the open source JPHP project. When Prosnis Loader is run, it starts a complicated malware delivery chain that eventually delivers SUNSPINNER and PURESTEALER, a commodity information stealer.

The malicious APK file aims to install a version of the commercially available Android backdoor CRAXSRAT on Android users. This payload was seen in a variety of forms, including one that had SUNSPINNER in addition to the CRAXSRAT payload.

Although support for macOS and iPhones is also advertised on the Civil Defense website, at the time of study, only Windows and Android payloads were accessible.

Notably, the Civil Defense website also uses an unusual kind of social engineering to allay user concerns about APK delivery outside of the App Store and provide justification for the high level of permissions needed to install CRAXSRAT.

In an attempt to “protect the anonymity and security” of its users, the website’s FAQ offers a strained defense for the Android application‘s hosting outside of the App Store, pointing users to a set of video instructions that go along with it.

After the malware is successfully installed, the Ukrainian-language video instructions show victims how to manually allow all permissions and disable Google Play Protect, a program that checks apps for malicious functionality when they are installed on Android devices.

Operation of Anti-Mobilization Influence

UNC5812 is participating in influence operations to thwart Ukraine’s broader mobilization and military recruitment initiatives in addition to its attempts to spread malware and obtain access to the devices of possible military recruits. Videos of “unfair actions from territorial recruitment centers,” which it believes likely to be meant for follow-on exposure to support UNC5812’s anti-mobilization narratives and disparage the Ukrainian military, are actively sought out on the group’s Telegram channel by users and subscribers. An attacker-controlled https://t[.]me/UAcivildefenseUA account is used to establish a chat thread when the “Send Material” (Ukrainian: Нaдіслати матеріал) button is clicked.

Additionally, there are anti-mobilization images and content in Ukrainian on the Civil Defense website, including a news section highlighting alleged instances of unfair mobilization tactics.

Cross-posted anti-mobilization propaganda on the group’s Telegram channel and website seems to come from larger pro-Russian social media networks. In at least one case, the Russian Embassy posted a video on South Africa’s X account a day after UNC5812 shared it.

Malware Analysis

From the group’s website, civildefense[.]com[.]ua, UNC5812 runs two distinct malware delivery chains for Android and Windows devices. The parallel release of a decoy mapping program known as SUNSPINNER, which shows users a map that represents the alleged locations of Ukrainian military recruits from an actor-controlled command-and-control (C2) server, is a commonality among these several delivery chains.

SUNSPINNER

The fake graphical user interface (GUI) program SUNSPINNER (MD5: 4ca65a7efe2e4502e2031548ae588cb8) was created with the Flutter framework and compiled for both the Windows and Android operating systems. The application’s GUI renders the map markers that SUNSPINNER requests fromhttp://h315225216.nichost[.]ru/itmo2020/Student/map_markers/mainurl.json, followed by a request for map markers from https://fu-laravel.onrender[.]com/api/markers that are then rendered on the app’s GUI.

According to the features listed on the Civil Defense website, SUNSPINNER can show crowdsourced markers that include the locations of Ukrainian military recruiters, and users can even add their own markers. Nevertheless, the presented map does not seem to contain any authentic user inputs, even though it has the minimal functionality needed for people to register and add markers. The same user added every marker found in the JSON file extracted from SUNSPINNER’s C2 infrastructure on the same day.

Pronsis Loader to PURESTEALER in Windows

CivilDefense.exe (MD5: 7ef871a86d076dac67c2036d1bb24c39), the Windows payload obtained from the Civil Defense website, is a customized version of Pronsis Loader, a newly identified commodity malware that is largely being used by threat actors with financial motivations.

The second-stage downloader “civildefensestarter.exe” (MD5: d36d303d2954cb4309d34c613747ce58) and the decoy SUNSPINNER binary are both retrieved by Pronsis Loader. This starts a multi-stage delivery chain that uses a series of self-extracting archives and finally runs PURESTEALER on the victim device. The open-source JPHP project is used to compile the PHP-written second-stage downloader into Java Virtual Machine (JVM) bytecode, which is subsequently created as a Windows executable file. The CivilDefense installer runs this file automatically.

PURESTEALER is the last payload (MD5: b3cf993d918c2c61c7138b4b8a98b6bf), a highly disguised commodity infostealer built in.NET, is intended to steal cryptocurrency wallets, chat apps, email clients, and browser data like passwords and cookies. “Pure Coder Team” is the company that sells PURESTEALER. Monthly subscriptions cost $150, while lifetime licenses cost $699.

CraxsRAT Android

A variation of the commercially available Android backdoor CRAXSRAT is the Android Package (APK) file “CivilDefensse.apk” (MD5: 31cdae71f21e1fad7581b5f305a9d185) that was downloaded from the Civil Defense website. File management, SMS management, contact and credential harvesting, and a number of location, audio, and keystroke monitoring features are all features that CRAXSRAT offers that are common to a conventional Android backdoor. It is also sold on underground forums, just like PURESTEALER.

At the time of investigation, the Android sample that was being circulated merely showed a splash screen with the “Civil Defense” logo. Nevertheless, it was discovered that the identical SUNSPINNER decoy application was present in another identified sample (MD5: aab597cdc5bc02f6c9d0d36ddeb7e624) as it was in the Windows delivery chain. This version downloads the CRAXSRAT payload from http://h315225216.nichost[.]ru/itmo2020/Student/map_markers/CivilDefense.apk after requesting the user’s Android REQUEST_INSTALL_PACKAGES permission.

Safeguarding Users

Google also keeps an eye out for Android spyware, and it implements and maintains Google Play Protect’s safeguards both inside and outside of Google Play, scanning devices for potentially dangerous apps from any source. Notably, the Civil Defense website of UNC5812 had social engineering content and comprehensive video instructions that directly instructed the intended user to disable Google Play Protect and manually activate the Android permissions needed for CRAXSRAT to operate. By alerting users before they access risky websites, Safe Browsing also protects Chrome users on Android. Google Play is protected by app scanning infrastructure, which also enables Verify Apps to further secure consumers who install apps from sources other than Google Play.

The national authorities of Ukraine have also been informed of its discoveries, and they have taken steps to limit the campaign’s reach by preventing the actor-controlled “Civil Defense” website from being resolved nationwide.

In brief

Following modifications to Ukraine’s national mobilization rules in 2024, Russian threat actors have increased their operational involvement in Ukraine, as seen by UNC5812’s hybrid espionage and information operation targeting prospective Ukrainian military recruits. The introduction of Ukraine’s national digital military ID, which is designed to handle the information of people due for military duty and increase recruitment, has specifically led to an increase in the targeting of prospective military recruits. It also continues to see consistent efforts by pro-Russian influence actors to spread messaging that undermines Ukraine’s mobilization drive and sows popular mistrust in the officials conducting it, in line with studies from EUvsDisinfo.

From a tradecraft standpoint, UNC5812‘s campaign exemplifies Russia’s focus on using its cyber capabilities to achieve cognitive effect and emphasizes the significant role messaging apps continue to play in the spread of malware and other cyber aspects of Russia’s war in Ukraine. It concludes that Telegram will very certainly continue to be a major conduit for cyber-enabled activity for a variety of Russian-affiliated espionage and influence operations as long as it remains a vital information source during the conflict.

Spring Boot vs Quarkus: A Comparative Analysis for Modern Java Development

Liberating industry with Java 

Java has been a great asset for developers in elevating the industry to higher standards. Java has a lot of built-in libraries and frameworks, which makes it easy for developers to build an application and website. It  is a set of built-in codes used by developers for building applications on the web. These frameworks possess functions and classes that control hardware, input processes, and communication with the system applications. The main purpose of preferring Java frameworks in development is that they provide a consistent design pattern and structure for creating applications. Moreover, this improves the code maintainability. This code consistency makes it easy for the developers to understand and change the code, neglecting bugs and errors. In Java, multiple frameworks are used, such as SpringBoot, Quarkus, MicroNaut, etc. In this blog, we will learn more about the differences between SpringBoot and Quarkus. Also, we will drive through the advantages of using it in the development process. 

Boosting development with SpringBoot and Quarkus:

SpringBoot is an open-source framework that supports Java, Groovy, Kotlin, and JIT compilation, which makes it very much easier to create, configure, and run microservice web applications. It is a part of the Spring framework that allows developers to utilize the Spring framework features. This makes it easy for the developers to expand and construct spring applications. It reduces the code length and also increases the production speed. This is possible due to the automated configuration of the application built on the Java annotations.

Quarkus is also an open-source Java framework that supports Scala, Java, and Kotlin. The major purpose of preferring Quarkus is to simplify the development and deployment process of Java applications in containers like Kubernetes and Docker. It is also used for developing microservice Java applications with a minimal consumption of resources. It is very easy to use and necessarily less demanding on hardware resources to run applications. 

Unbinding the differences between SpringBoot and Quarkus

Quarkus will be performing better because of its Kubernetes native framework, which is designed particularly to run in a containerized environment. Moreover, it uses an Ahead-of-time (AOT) compiler for pre-compiling the Java bytecode into native code. This results in faster start-up time and lower usage of memory. But, on the other hand, SpringBoot is a traditional Java framework that uses the Java Virtual Machine (JVM) to run applications. SpringBoot can also run on the containerized environment but it doesn’t have the same performance level optimization as Quarkus. 

The greatest difference between Quarkus and SpringBoot is the size of the frameworks. SpringBoot is a well-established and feature-rich framework, but it comes with vast dependencies, which increases the application size. On the other hand, Quarkus is a new framework that has a much smaller runtime footprint when compared with SpringBoot. It also has a feature for optimizing the size of the application. SpringBoot has been in the industry for a long period of time, it has a larger community and a vast ecosystem of libraries and plugins. Quarkus is a relatively new framework in the industry, but it is attracting a lot of developers to its side. The community of Quarkus is small when it is compared with SpringBoot. 

Conclusion 

From this blog, we can understand the impact of Java and its crucial role in the development of applications. SpringBoot and Quarkus has made quite an impact in developing applications and websites in an unique way. Both of these frameworks have been a great asset for most developers to create an interactive application. Preferring the perfect Java application development company also plays an important role in a company’s growth.
