Kaspersky experts have provided valuable information on identifying deepfake audio, the term “deepfake” is a combination of “deep learning” and “fake,” which refers to a type of artificial intelligence that has rapidly evolved over recent years.
Artificial intelligence can be utilized to create convincing fake images, videos, and audio content, to distinguish between authentic and manipulated audio clips, several characteristics need to be examined, such as the tone, manner, and intonation of the voice.
Deepfake audio often exhibits an unnatural monotony in speech, another critical aspect to consider is the sound quality, hence, attention should be given to any distorted speech or unusual noises when listening to a message or voice call.
While deepfake technology itself is not harmful, it can become a dangerous tool in the hands of fraudsters who might exploit it for deception, defamation, or misinformation.
However, there have been no widespread cases of voice-changing deception so far, although some notable instances involved deepfake voice forgery.
In 2019, scammers used this technology to steal from an energy company in the United Kingdom, they published a phone conversation where the scammer pretended to be the CEO of a major German company and urgently requested a transfer of 220,000 euros to a supplier’s account, one year later, in 2020, scammers employed deepfake technology to steal up to 35 million dollars from a Japanese company.
Dmitry Anikan, Kaspersky’s Chief Data Scientist, expressed his views, saying, “At present, there is no widely available high-quality deepfake technology, but its potential future availability could lead to an increase in fraudulent activities in this field.
Attackers might generate momentary voices to impersonate someone close to a person to seize funds, this scenario seems unrealistic at the moment, as developing high-quality deepfake technology requires substantial resources.
If the goal is to produce low-quality fake audio, fraudsters would require fewer resources, which is something they can resort to at present. As a result, there are signs that can be used to detect such fraud.”
Kaspersky’s Recommendations:
To protect yourself from deepfake deception, Kaspersky experts suggest the following:
1. Be cautious of suspicious calls: Pay attention to poor voice quality, unnatural speech patterns, unclear speech, and unusual background noises.
2. Avoid making emotional decisions and refrain from sharing personal data or transferring money, even if the conversation seems convincing, instead, hang up and verify the information through multiple channels.
3. Rely on reliable security solutions, such as Kaspersky Premium, and install them on your devices to enhance the security of your tools.
