IN THE WEEKS since Elon Musk was forced to complete his acquisition of Twitter for $44 billion, the social network has been in a state of dramatic upheaval. Musk laid off more than half its workforce and fired more via public tweets. Digital infrastructure went on the fritz. And today, a reported 75 percent of staff refused to sign a pledge to work "long hours at high intensity," ostensibly triggering their resignations. It's now unclear who still works at Twitter. In short, all hell is breaking loose at the bird site. As the chaos mounts, one consequence inside the company could be less attention on digital security monitoring and fewer dedicated staffers working to defend Twitter from cyberattacks. And that could put the company and its users at increased risk of a massive data breach or another security incident.
