As COVID-19 ravaged hospitals’ patient care units last year, opportunistic criminals saw an opportunity to pluck low-hanging fruit: Hacking groups decided to breach and ransom healthcare institutions during a time of global crisis.

Recently, two teens and a young adult infiltrated one of Silicon Valley’s biggest companies in a high-profile hack – and the biggest ever for Twitter. Authorities say the 17-year-old “mastermind” used social engineering tactics to convince a Twitter employee that he also worked in the IT department and gained access to Twitter’s Customer Service Portal. The 130-account takeover proved unique, as it was fundamentally a dramatic manipulation of trust and could have had far more world-changing consequences if the attackers had the aspirations of say, a dangerous fringe group versus that of a teenager. There are a few takeaways to learn here, especially when it comes to considering redefining what we classify as “critical infrastructure” and what must be protected at all costs.
