A deepfake is a video or audio clip generated using artificial intelligence (AI) that mimics a person’s likeness or voice to depict events or statements that never actually happened. These AI-forged creations can seem incredibly realistic and are often used in scams, misinformation campaigns, and other forms of digital manipulation, sparking significant cybersecurity concerns.
The word "deepfake" is a mash-up of “deep learning” (a type of AI) and “fake,” describing how this technology uses advanced machine learning to create realistic imitations.
At the core of deepfake technology is the Generative Adversarial Network (GAN), where two AI systems work together. One creates the fake content, while the other critiques it, improving its believability over time in a repetitive cycle. By processing massive datasets of images, videos, and audio clips of a person, the system learns to simulate their likeness and mannerisms convincingly.
Modern tools allow even those with no technical expertise to create deepfakes, thanks to user-friendly apps and software making this technology more accessible. While powerful in the right hands, its misuse elevates cybersecurity challenges globally.
Deepfakes represent serious cybersecurity risks, including:
Fraud Attacks: Deepfake audio or video can impersonate company executives, authorizing fake wire transfers or giving false instructions, a tactic known as “CEO fraud.” Scammers have successfully stolen millions with this technique.
Misinformation and Propaganda: Deepfake videos can spread false information online, undermining trust in news and fueling confusion during critical events like elections or crises.
Privacy Violations: Malicious actors can use deepfakes to damage personal reputations, often by creating fake explicit content or using them for blackmail.
Erosion of Trust: By making it harder to distinguish real content from fake, deepfakes undermine public trust in genuine media, heightening uncertainty and skepticism about truth online.
These threats aren’t hypothetical; they’ve already been seen in real-world incidents targeting both individuals and organizations. Staying vigilant and adopting countermeasures is essential to mitigate their impact.
"We can no longer trust voice authentication over the phone,” said Ben Bernstein, technical account manager at Huntress. “I could effortlessly feed an interview or podcast into a deepfake AI solution, effectively training it to mimic a target's voice. Imagine that AI then calling a helpdesk to reset a password or impersonating an executive to extract sensitive financial data. MSPs especially need to recognize this escalating threat and implement stronger verification methods.”
Detecting a deepfake can be tricky, but some telltale signs include:
Unnatural Movements: Look for overly rigid or unnatural facial expressions, body language, or eye blinks.
Visual Artifacts: Blurry edges, mismatched lighting, or flickering in the video may hint at manipulation.
Audio Irregularities: Pay attention to speech patterns, tone mismatches, or any noticeable syncing issues between lip movement and sound.
Cross-Check the Context: If the message or video seems unusually controversial or odd, verify it against other credible sources.
Emerging tools and AI-based detection systems are being developed to help identify deepfakes more reliably.
In this episode, the mayor of Sludge Springs, cooks up a deepfake to trick Curriculaville’s sanitation worker, Jacob, in hopes of sabotaging their clean town record.
This episode dives into how deepfakes are created, the risks they pose in daily life, and steps you can take to spot and protect against them. Will Jacob see through the scheme, or will AI win the day?
Train Your Team: Provide security awareness training to employees on deepfakes and how they might be used in phishing attempts or executive impersonation schemes.
Verify Requests: Always confirm instructions or financial transactions through a secondary communication channel before acting.
Leverage Detection Tools: Use AI-based tools designed to analyze video and audio metadata for potential tampering.
Strengthen Security: Secure your organization’s infrastructure with comprehensive cybersecurity measures, including multi-factor authentication (MFA) and endpoint protection to defend against associated threats like phishing or malware.
Be Skeptical: Foster critical thinking habits when consuming media, teaching employees and the general public to question and verify suspicious content.
Deepfakes can surface in numerous scenarios - both good and bad. Here are some notable examples:
Entertainment: Recreating deceased actors in films or editing scenes for creative storytelling.
Satire and Humor: Swapping faces of public figures in viral meme videos.
Cybercrime: Using deepfake voice calls to impersonate executives and authorize fraudulent transfers.
Political Misinformation: Spreading fake speeches or doctored videos to discredit politicians or manipulate opinions. Read more in our blog post, Protect Yourself from Political Donation Scams.
In another unique example, a deepfake of a murder victim was was used in court. Check out our Tradecraft Tuesday clip with Truman Kain and Chris Henderson discussing this unique AI deepfake use case where a judge allowed an impact statement by the deceased individual.
Deepfakes blur the line between reality and fiction, creating unprecedented risks. From financial fraud to undermining democracy, their misuse could harm individuals, organizations, and society as a whole. Malicious use erodes trust in legitimate content while increasing the effort and resources required to verify authenticity.
On the flip side, deepfakes can be a force for good when used responsibly, enabling creative projects, preserving cultural heritage, and advancing education. The key lies in using this technology ethically while addressing its potential harms head-on.
Deepfakes are the perfect example of how emerging tech can be twisted into a cybersecurity nightmare. Their role in phishing, misinformation, and privacy violations makes them a growing cybersecurity concern. But here’s the good news: Huntress is built to combat these evolving threats.
