Palo Alto Networks put out fixes for six vulnerabilities across several of its security products, InfoSecurity Magazine reported. Separately, rival Trend Micro also issued a handful of security patches. Both vendors said they hadn't seen their respective bugs exploited in the wild. 

Deepfakes are surpassing deepfake detection. Fake voices, images and video are getting so realistic as AI advances that tools for picking out the imposters are falling behind, cyber and AI experts say. A study from cyber company Pindrop found that big banks received an average of two deepfake fraud attempts per day in early 2024. By the end of the year, that had grown to more than five daily, Pindrop said. (SecurityWeek)
