Tel Aviv, Israel – Recently unsealed court documents have exposed significant details about the operations of Israeli spyware vendor NSO Group and its controversial tool, Pegasus. These revelations came to light during the intensifying legal battle between Meta’s WhatsApp and NSO Group, providing an in-depth look at the ethical and security complexities surrounding the use of spyware.
The case against NSO Group escalated after it emerged that the company had leveraged multiple vulnerabilities in WhatsApp to deploy its Pegasus spyware, a practice that persisted even after WhatsApp initiated a lawsuit in October 2019. Notably, one attack, exploiting a critical flaw in the app’s video calling feature, successfully compromised user devices by bypassing WhatsApp’s enhanced security measures implemented post-2018.
NSO Group developed a series of installation vectors, named collectively as Hummingbird, including ‘Erised’ which exploited the aforementioned vulnerability and was active even following the lawsuit. According to the documents, NSO’s malware exploited WhatsApp’s messaging infrastructure to deliver manipulated messages, forcing target devices to connect to an NSO-controlled server, facilitating the unauthorized installation of spyware.
The documents further unravel how Pegasus operates by illustrating that NSO, not its clients, manages the installation and operation of the spyware. This contradicts NSO Group’s previous claims stating that their clients, concerned with combating serious crimes and terrorism, solely operate the gathered intelligence. NSO admits the spyware has been forcibly installed on numerous devices without user interaction, ranging from hundreds to tens of thousands.
Meta’s legal filings expose the severe extent of this covert surveillance, highlighting that NSO engineered these cyberattacks by decoding and re-engineering WhatsApp’s code to execute unauthorized commands from their servers, breaching both U.S. laws and WhatsApp’s terms of service. This manipulative method bypasses telecommunication authentications and significantly compromises user privacy.
Meanwhile, tech giant Apple recently decided to withdraw its lawsuit against NSO Group. The decision, made in September 2024, was influenced by risks of publicizing sensitive threat intelligence that could jeopardize user security. In parallel, Apple has been enhancing its device’s defenses against such intrusions, introducing new features like the Lockdown Mode to mitigate risks from mercenary spyware attacks.
As companies continuously adapt with robust security measures, reports have surfaced on a security feature in upcoming iOS 18.2 versions. This feature aims to further secure devices by automatically requiring a password re-entry if the device hasn’t been unlocked within 72 hours. Expert forensic firms acknowledge the criticality of this feature in ensuring data integrity during legal examinations.
This scenario underscores the ongoing tension between maintaining national security and protecting individual privacy rights in the digital age, attracting global scrutiny and demands for stringent regulatory oversight on spyware products.
