Mexico City (AP) - Following a cyber attack on the Mexican oil company Pemex, the company faces a blackmail attempt. Pemex is a serious company and therefore will not pay, according to the Ministry of Energy. According to the media, a hacker had demanded a ransom of 565 Bitcoin, or around 4.5 million euros, to decrypt data encrypted in last Sunday's cyberattack. According to Pemex, cyber attacks had been "neutralized". The operation continues to run normally and the gasoline inventory is secured.
