Ex-Meta Security Head Sues Over Alleged WhatsApp Vulnerabilities, Claims Retaliation
September 8, 2025
Meta reported a 21.1% revenue growth over the past year, reaching $178.8 billion, with high profitability margins and solid financial health, including low debt and high liquidity.
The lawsuit underscores the ongoing tension between technological innovation and security, with potential implications for user trust and regulatory oversight.
Attaullah Baig, a former security head at Meta, has filed a lawsuit against the company, alleging that it ignored security warnings and retaliated against him after he raised concerns about WhatsApp's vulnerabilities and privacy violations.
While Meta's financials are strong, recent insider selling suggests some internal concerns about the company's future prospects.
This case exemplifies the growing influence of whistleblowers in holding tech giants accountable and could lead to broader reforms in transparency and security practices.
The lawsuit follows Meta's 2020 settlement related to the Cambridge Analytica scandal, highlighting ongoing issues with data privacy and security.
Baig claims that approximately 1,500 engineers had unrestricted access to user data, including personal information and profile photos, which could be moved or stolen without detection, raising serious security concerns.
Despite these issues, analyst sentiment remains positive, with a target stock price of around $850 and a recommendation score indicating neutral market sentiment.
Despite legal and regulatory challenges, Meta's financial strength and competitive advantages position it for continued growth and resilience.
Meta's market capitalization stands at approximately $1.89 trillion, with a stock price of $752.3, reflecting its dominant position in the market.
As the case unfolds, it may reveal internal communications that shed light on Meta's operations, with privacy advocates emphasizing the importance of maintaining trust in encryption.
The lawsuit could attract regulatory scrutiny and potentially impact Meta's legal and reputational standing if security vulnerabilities are confirmed.
