A recent fact-checking analysis has scrutinized the methodology of Forbidden Stories' investigation into the Pegasus spyware, which alleged widespread surveillance by governments using NSO Group's tool. The analysis, published on July 19, 2026, highlights potential weaknesses in the evidence chain, particularly regarding the verification of phone numbers and the reliability of the data sources.
The original investigation, coordinated by Forbidden Stories and involving multiple media partners, claimed to have identified over 50,000 phone numbers linked to potential targets of Pegasus surveillance. However, the fact-checking report notes that many of these numbers could not be independently verified, and some may have been obtained through unconfirmed leaks or unverified databases.
NSO Group has consistently denied the allegations, stating that its technology is only used for legitimate law enforcement and counterterrorism purposes. The company has also challenged the methodology of the investigation, arguing that the data does not prove actual surveillance occurred. As of July 2026, no court has validated the claims made by Forbidden Stories.
The fact-checking analysis concludes that while the investigation raises important questions about surveillance, its findings should be treated with caution due to the lack of independent verification. It recommends that future investigations adopt more rigorous standards to ensure the reliability of their evidence.
