Facebook among tech firms to sign 'digital Geneva convention'

Signatories including Microsoft, Arm and Trend Micro agree not to take part in cyber-attacks

More than 30 global technology firms have signed up to a "digital Geneva convention", committing never to partake in cyber-attacks against individuals or businesses.

The signatories to the "cybersecurity tech accord", which include Facebook, Microsoft, Arm and Trend Micro, are largely from the US and western Europe, and do not include companies from the countries seen as most responsible for the recent escalation of digital hostilities, such as Russia, North Korea and Iran.
