Free Trojan Config

[Galeno Kent]

Thisforward config is for port forwarding through a trojan connection. Everything is the same as the client config, except for target_addr and target_port, which point to the destination endpoint, and udp_timeout, which controls how long (in seconds) a UDP session will last in idle.

Emotet is a Malware using multiple elements to create havoc in an infrastructure. Our Greenbone Security Feed now has a Vulnerability Test that checks for these elements. It strengthens your resilience and finds assets potentially compromised.

The attached scan configuration supports you to detect possible Misconfigurations and Vulnerabilities within your environment and to limit the initial attack vector via Microsoft Office Macros and the spreading of Emotet after the initial infection.

The VT Disabled Macros for Office Applications (Emotet Protection) (OID: 1.3.6.1.4.1.25623.1.0.109713) gives a Log level report entry with a brief overview over the current Office Settings which are compliant and should help protecting you against Emotet. It also includes a list of items which needs to be reconfigured and the info what needs to be configured to be compliant.

At the request of a coworker, I was asked to extract the configuration of a LuminosityLink sample, and while I could have simply executed the malware in a sandboxed environment and pulled the configuration from memory, I chose to see if I could perform the same action against the static binary.

LuminosityLink currently sells for $40 and can be purchased directly from its author. This package allows attackers to host a LuminosityLink server as well as generate customized binaries, which are obfuscated with ConfuserEx 0.4.0. ConfuserEx is an open-source project that obfuscates the underlying .NET code, making it much more difficult for reverse engineers that decompile it. This is important to note for later when we discuss determining how to reverse-engineer the encryption process.

The first step in parsing out the configuration of LuminosityLink is to extract it statically. I initially opened up a clean LuminosityLink sample using a program named dnSpy to search for clues as to where the configuration might be stored. (As a quick aside, I highly recommend dnSpy, as it not only does a great job of decompiling the provided .NET binary, but it also comes equipped with a built-in debugger, which is instrumental in tackling problems such as the one we are facing.)

At this point, I turned to my debugger in an attempt to see how these strings were handled. I set breakpoints on various calls previously mentioned. Specifically, the breakpoint on the RijndaelManaged class yields excellent results.

Using this knowledge, we created a script to parse the configuration of a given sample. The script searches for strings that appear to be base64-encoded with a length greater than 50 and takes a brute-force approach. While not elegant, it does the job quite successfully. The script can be downloaded in the Appendix section of this blog post.

Going through Palo Alto Networks repository of samples, we found roughly 18,000 files tagged as LuminosityLink. For these 18,000 samples, we applied our static configuration extraction and parsing script and successfully retrieved about 4,500 configurations. The remaining samples were packed beyond the built-in ConfuserEx obfuscation routine, and as such, the raw configuration strings were not present.

These samples were run through a local instance of the open-source Cuckoo Sandbox, where the process dumps were extracted. The same script was applied to these process dumps, where we were able to obtain an additional 10,200 configurations, leaving us with a total of 14,700 parsed LuminosityLink configurations.

It appears as though the author of LuminosityLink is not without a sense of humor. Additionally, as we parsed older samples, it was discovered that the configuration made a change sometime between February and June of this year. Fewer options were available in the configuration of older samples. The provided script accounts for these differences and various keys used.

LuminosityLink, while marketed as a systems administration utility, is a formidable keylogger and backdoor used by a large number of criminals. To date, Palo Alto Networks has witnessed over 50,000 attempted infections of LuminosityLink, encompassing 18,000 unique samples. The malware is cheap and readily available to the public, making this a dangerous threat to both organizations and individuals alike.

By reverse-engineering LuminosityLink samples, we were able to statically extract and parse the embedded configuration, which in turn provides valuable information about with what hosts and ports the malware is configured to communicate. It also provides information regarding configured protections configured within the executable, as well as installation information.

One more question. If one of the units fails, and I want to switch to a single unit, re-wiring appropriately, is there a way to bring the units back to factory defaults and program with dip switches or do I have to go into VE-config with my windows laptop?

And you've paralleled up 3x strings. and that's definitely not lab conditions. I'd be inclined to ease-up on the 14.8 Abs because of that. The Float won't really matter much. I use 14.4V Abs (+/- temp comp).

The reason I unplug the cable (it's just a standard RJ45 connection, like ethernet) from the CCGX and use that with the Mk3 is that the instructions for the Mk3 specify to unplug any CCGX/Venus components before using the Mk3 anyway.

As I said (and maybe wasn't clear) as far as I can tell changing settings over the network requires going through the VRM portal which also requires an internet connection I don't believe you could update them just with a local LAN.

I hear ya re the redundancy. A pal of mine recently asked why I have 2x of everything. I replied "Ahh, not the Victron kit, don't need it". Bit of a white-lie there though, I could cover it with a little wire-swinging, but that's what you do in an emergency.

Xray's Trojan has full support for fallbacks, and the configuration is identical. The conditions triggering fallback are similar to VLESS: first packet length "Trojan GFW" and "Trojan GO" refers to a tool that uses multiple protocols over TLS to bypass internet censorship and filtering systems, such as the Great Firewall of China (GFW). By disguising itself as a common service, Trojan GFW/GO aims to avoid detection and Quality of Service limitations imposed by internet service providers. The goal of Trojan GFW/GO is to provide a mechanism for bypassing internet censorship permanently and without being identified

TLS is a cryptographic protocol that provides secure data transmission over a network, most commonly the internet.It works by encrypting data to protect it from eavesdropping and tampering during transit. TLS operates at thetransport layer of the OSI model, ensuring a secure channel between two communicating parties. It employsvarious encryption algorithms and digital certificates to authenticate and establish secure connections.

SSL was the precursor to TLS and served as the foundation for the latter. While TLS is the modern, more secureversion, SSL is still used and recognized. SSL, like TLS, creates secure connections by encrypting data andensuring data integrity. However, it is considered less secure due to known vulnerabilities, and its usage isgenerally discouraged in favor of TLS.

Web Sockets are a different breed of technology, focusing on real-time, bidirectional communication over a single,long-lived connection. Unlike traditional HTTP connections that are stateless, Web Sockets maintain a continuous,low-latency connection that is ideal for applications requiring instant updates and interactions, such as chatapplications and online gaming.

It's essential to note that the security of these technologies heavily depends on proper implementation,configuration, and regular updates to address emerging threats and vulnerabilities. While TLS and SSL arefocused on securing data transmission, Web Sockets add a layer of real-time, bidirectional communication, extendingthe capabilities of web applications. When combined with best practices and vigilant security measures, thesetechnologies contribute significantly to the protection of data and privacy in the digital world.

In our interconnected world, the importance of server geo-location cannot be overstated. The physical location of a server, where data is stored and distributed, has a significant impact on the performance, security, and user experience of online services. Whether you're running a business website, an e-commerce platform, or a content delivery network, understanding the implications of server geo-location is essential for success in the digital age.

In summary, the importance of server geo-location in the digital world cannot be overlooked. It influences website performance, SEO rankings, security measures, content delivery, and marketing strategies. To succeed in the competitive online landscape, consider the geo-location of your servers as a strategic advantage that can enhance user experiences and drive business success.
