Cryptominers Found in Audio Files
Researchers have recently found that both cryptominers and backdoors are being deployed within WAV audio files on targeted systems.

Along with the malicious software, Monero cryptominers were launched simultaneously to begin generating cryptocurrency.

Darknet Child Porn Distribution Site Shutdown
Officials in the U.S. and South Korea collaborated to shut down a darknet site thought to be the largest distribution site of child porn. More than 300 individuals were arrested in connection with the site. By monitoring new Bitcoin addresses created when users made an account, the officials were able to find not only hundreds of users, but also the site’s administrator, who has since been charged in South Korea. Most alarmingly, amongst the 250,000 videos found on the server, nearly half were previously unknown to law enforcement.
