Take the case of the false tweet sent from the US’s Associated Press Twitter handle. This resulted in a US$136.5 billion drop in the S&P 500 index’s value in just a few minutes. Cybersecurity best practice for CNI and beyond Government-related social media accounts used for timely or sensitive communications should be treated as CNI, subject to the same cybersecurity best practices adhered to by the energy, transportation and chemical sectors. Government social media accounts – like Twitter, Facebook, YouTube, LinkedIn and more – are typically shared accounts, meaning that teams of people throughout an agency have access and can post information to them. The passwords for these accounts are commonly shared internally among team members. This makes them extremely easy targets for attackers or malicious insiders. The shared nature of these accounts also means there is no record kept of who posted what when – making a deliberate false alert a tangible reality. To add to the headache, passwords used to ‘secure’ these accounts are rarely changed and typically used across multiple accounts. By treating these accounts as privileged, organisations can be safe in the knowledge that a simple forgotten password doesn’t delay communications, while also hardening these platforms against external hacks. 45
