The latest episode of this podcast explores a range of major cybersecurity and technology developments. Microsoft has officially announced the discontinuation of Skype after 14 years, shifting its focus to Microsoft Teams. Amnesty International has revealed that Cellebrite's software, exploiting a zero-day vulnerability, was used to unlock the Android phone of a Serbian activist, raising concerns over privacy and surveillance. Meanwhile, the Qilin ransomware group has allegedly attacked Lee Enterprises, leaking sensitive data online. Authorities have also dismantled a network distributing AI-generated child sexual abuse material. NHS staff have expressed skepticism about the adequacy of cybersecurity measures protecting the UK’s health service, citing a lack of training. A new Vo1d malware variant has infected nearly 1.6 million Android TV devices worldwide, with a dramatic spike in India. Serbian police's reported use of Cellebrite’s zero-day vulnerability highlights the debate between law enforcement access and digital privacy. Lastly, cybercriminals are using fake Captcha PDFs to spread the Lumma Stealer malware via platforms like Webflow and GoDaddy, demonstrating the evolving nature of malware distribution.
