Social engineering continues to be the primary gateway for cyberattacks, responsible for nearly 80% of fraud and ransomware incidents. And notably, 1 in 4 of these social engineering attacks originate via phone calls. Yet many enterprises continue to leave their phone systems exposed. In this episode, Dr. Dave Chatterjee engages Richard Quattrocchi, Vice President of Digital Transformation, Mutare Inc., in a compelling discussion on the often-overlooked threat of voice-based cyberattacks, particularly vishing (voice phishing). Richard shares his professional journey, personal motivation rooted in a family scam incident, and the alarming rise of social engineering via phone calls—especially in the era of AI and deepfakes. The conversation underscores how organizations continue to leave phone systems vulnerable due to siloed ownership and outdated assumptions.Richard presents a layered defense strategy combining people, process, and technology, and introduces Mutare’s voice traffic filtering solution. This technology proactively intercepts malicious calls using metadata analysis before they reach users, drastically reducing exposure to fraud. The discussion also dives into real-world cases, including the MGM breach, and offers actionable guidance for enterprises and individuals to better secure voice channels.To access and download the entire podcast summary with discussion highlights -- https://www.dchatte.com/episode-84-stopping-social-engineered-vishing-attacks-before-they-start/Connect with Host Dr. Dave Chatterjee and Subscribe to the PodcastPlease subscribe to the podcast so you don't miss any new episodes!

In this episode, Aaron Painter, CEO at Nametag, joins me in discussing the Deepfake fraud phenomenon and how organizations and individuals should protect themselves from such scams. A recent study conducted by finance software provider Medius finds that over 53% of businesses in the U.S. and U.K. have been targets of financial scams powered by “deepfake” technology, with 43% falling victim to such attacks. 85% of the finance professionals polled view such scams as an “existential” threat to their organization’s financial security. In the United States, families lose an average of $11,000 in each fake kidnapping scam. According to data from the Federal Trade Commission, Americans lost $2.6 billion last year in imposter scams.To access and download the entire podcast summary with discussion highlights --https://www.dchatte.com/episode-77-stopping-deepfake-threats-protecting-organizations-through-identity-verification/Latest Articles and Press Release on The Cybersecurity Readiness Podcast Series:Cybersecurity Readiness Podcast by Dr. Dave Chatterjee Reaches 10,000 Downloads Globally, Business Insider/Markets Insider, Dec 10, 2024.Dr. Dave Chatterjee Hosts Global Podcast Series on Cyber Readiness, Marketers Media, Dec 12, 2024.Connect with Host Dr. Dave Chatterjee and Subscribe to the PodcastPlease subscribe to the podcast so you don't miss any new episodes!
