Yahoo laid off around 25% of its cybersecurity team — known as The Paranoids — over the last year, TechCrunch has learned. From the report: Overall, the company has laid off or lost through attrition 40 to 50 people from a total of 200 employees in the cybersecurity team since the start of 2024, according to multiple current and former Yahoo employees who spoke to TechCrunch on condition of anonymity. (Yahoo is TechCrunch’s parent company.)

The Paranoids are not the only team affected by the layoffs. Valeri Liborski, who was appointed Yahoo’s chief technology officer in September, sent an email this week to employees announcing changes across the broader technology unit, including enterprise productivity and core services. The email to staff, which was obtained by TechCrunch, said: “This was a very difficult decision and one I have not taken lightly.”

The Paranoids’ so-called red team, or offensive security team — which conducts cyberattack simulations to identify weaknesses in the company’s network before external hackers can — was eliminated entirely this week, and there have been at least three rounds of layoffs impacting the cybersecurity team this year, according to the sources.
