Responsibility:- Developing services in C/C++,for the purposes of network analysis.- Working with map service «GIS Panorama» in AstraLinus (SE), creating and supporting services in Python for editing layers of map in automatic mode.Network analisys.The software being developed carries out network analysis and extracts maximum information from the hosts. The input is a range of IP addresses that are monitored by the kernel (which was used from Zabbix), extracting information such as accessibility (online/offline), device type. If possible (PC, router, switch, printer, etc.), if the OS is extracted, its version, available general technical data about the object (GPS, car type, speed, etc.). Development in C, build with autotools.A separate remote-control module that sends commands via SNMP to remote PCs or routers (node reboot, on/off). Development in C++, build with cmake.Map service.All objects have their own GPS coordinates and the GIS Panorama map service is used for drawing on the map. Since the read information is regularly updated when the position of the object changes, or when going online/offline, the corresponding changes are reflected on the map. Development in Python.These and other modules of the system communicate with the backend and information is transmitted for display on the frontend (project site).

I worked with different tasks.· A poker helper that gives suggestions to players. Player sets necessary condition of game (player’s cards, number of players, stage of game, etc.) in the application by using buttons on one side of the window and the program shows help by representing colored zones on the “card matrix” with weights on the other side. Math info for counting was imported from xlsx file from the cloud. An auth functions was added by checking the hardware of the used computer system which was compared with list of hashes of validated users who were listed in special file in internet.· Deep learning of network protocols. A sniffer of raw packets in C was developed for packet analysis. Captured packets are parsed by created program and represented on the user screen with marking of defined of the most important parts like headers, flags and packet payload of protocol.· Creation of cryptographic plugin for browser on the framework Firebreath 2.0. Plugin was based on existed library that included different cryptographic functions, interface of class with describing what methods should do. By using these functions was created plugin for browser that provide encryption, data signature, checking of signature for data in browser. Build with cmake.· Research of executable PE/ELF files. There was realized injection in executable file for Windows OS using functions from library. Original executable file (.exe) was modified in hex editor (used HIEW). There was changed import table: added new record with new library description and functions specification of it - 20 bytes structure. And, as a result in start of the file the function from library started automatically. Library injection changed binary file functionality without recompiling of it.

Projects:· Factory production monitoring system. A complex system was developed to monitor all components mounted into products in the factory to provide support for accounting and provide traceability of products and their sub-components.· Searching vulnerabilities of SCADA systems. During researching of vulnerabilities SCADA systems there were created packets what send on aim host to make some influence for system.
