Malware, Cats and Cryptography - Zhassulan Zhussupov

Research in the field of reimplementation of ransomware and the role of cryptography in malware development. Application of classical cryptographic algorithms for payload and ransomware encryption. Practical research has been carried out: the results of using Skipjack, TEA, Madryga, RC5, A5/1, Z85, DES, mmb, Kuznechik, etc. encryption algorithms have been analysed. The application of cryptography based on elliptic curves is also being researched. How does all this affect the VirusTotal detection score and how applicable is it for bypassing AV solutions (AV bypass). In some researched practical cases, we get FUD malware. Bypass AV Kaspersky, Windows Defender. ESET NOD32 in some practical cases. Reverse engineering and code reconstruction with malware development tricks from ransomware and malware like Conti, Snowyamber, Paradise Ransomware, CopyKittens, Hello Kitty etc. Discovered new tricks from Russian APT29 related malware.
