Yung earned his Ph.D. from Columbia University in 1988 under the supervision of Zvi Galil. In the past, he worked at the IBM Thomas J. Watson Research Center, was a vice president and chief scientist at CertCo  and was director of Advanced Authentication Research at RSA Laboratories. He has also held adjunct and visiting faculty appointments at Columbia through which he advised several Ph.D. students including Gödel Prize winner Matthew K. Franklin and Jonathan Katz.
In a 1996 publication with Adam L. Young, Yung coined the term cryptovirology to denote the use of cryptography by computer viruses and other malware and discovered the secure attack (from the attacker's perspective) for kidnapping data known as ransomware.  Young and Yung authored the book Malicious Cryptography: Exposing Cryptovirology (John Wiley & Sons, 2004). (See also ) In 1996 Yung and Young introduced the notion of kleptography to show how to use cryptography to attack host cryptosystems where the malicious embedded cryptologic resists reverse-engineering. The first such attack against a real system is believed to have been mounted by NIST against an American Federal Information Processing Standard detailing the Dual_EC_DRBG (essentially exploiting the repeated discrete logarithm based "kleptogram" introduced in 1997 by Young and Yung).
Yung has contributed extensively to the foundations of basic cryptographic systems and protocols (such as to innovating the notion of public key cryptosystems secure against chosen-ciphertext attack, which is currently a major requirement from public-key encryption schemes operating on the Internet), as well as to numerous new cryptographic ideas and techniques. He also contributed to various constructions, leading to practical implementations and use in actual systems and networks.
Awards: Moti Yung was the annual Distinguished Lecturer of the International Association for Cryptologic Research at Eurocrypt 2010. In 2013 he became a fellow of the Association for Computing Machinery (See also ). In 2014 he became a fellow of the International Association for Cryptologic Research, and in 2015 he became an IEEE fellow. In 2014 he received the ESORICS (European Symposium on Research in Computer Security) Outstanding Research Award  and he received the ACM's SIGSAC Outstanding Innovation Award.
