doublespeed / a16z / phone farm

A hacker breached an older backend queuing system at Doublespeed, an a16z-backed startup that runs a phone farm to create AI-generated TikTok influencers, and attempted to queue a meme calling Andreessen Horowitz “the antichrist” for publication across customer accounts. Screenshots seen by 404 Media show the intruder claiming to have exfiltrated 47MB, made 573 accounts postable and dumped 413 phones, though Doublespeed says the malicious post was not published and the issue was quickly secured. Doublespeed previously suffered a December 2025 breach exposing hundreds of fake TikTok accounts; the company markets its tools to evade platform authenticity rules. The incident raises questions about security and the ethics of AI-driven inauthentic social media operations.

A hacker claimed responsibility for breaching a phone-farm operation backed by venture firm a16z, defacing signage with the phrase "antichrist" and publicizing the intrusion. The report — circulating via 404 Media and linked on Hacker News — implicates attackers targeting large-scale device farms that provision and manage many smartphones for automation, testing, or ad-fraud. The incident highlights risks around insecure device management, exposed remote-access interfaces, and weak authentication in distributed mobile infrastructure. It matters because phone farms are used by startups, ad-tech operators, and QA teams; compromises can yield data theft, fraud, loss of device integrity, and reputational damage for investors and operators. Security practices for IoT-like mobile fleets need stronger controls and monitoring.

A hacker breached Doublespeed, an a16z-backed startup that operates a phone farm to create AI-generated TikTok influencers, and queued a meme labelling Andreessen Horowitz “the antichrist” for customers’ accounts, according to screenshots obtained by 404 Media. The intruder reportedly exfiltrated 47 MB, flagged 573 postable accounts and dumped 413 phones, though Doublespeed says the compromised legacy post-queuing system was secured and no unauthorized posts went live. This is at least the second breach of Doublespeed (a prior December 2025 compromise exposed hundreds of inauthentic TikTok accounts). The episode spotlights security and ethical risks around commercialized AI-generated influence operations and platform policy evasion, and raises questions for investors and platforms linked to the startup. Key players: Doublespeed, a16z, Marc Andreessen, 404 Media.

A hacker breached Doublespeed, an a16z‑backed startup that runs a phone farm to create AI-generated social accounts, and queued a meme labeling a16z “the antichrist” to be posted from hundreds of compromised accounts, according to screenshots obtained by 404 Media. The attacker claimed 47MB exfiltrated, 573 accounts postable and 413 phones dumped, but the posts do not appear to have been published. Doublespeed co‑founder Zuhair Lakhani said the intrusion targeted an older queuing system that has been secured and that there’s no evidence of broader customer impact. The incident follows a prior December 2025 breach and raises questions about the security and ethics of automated influencer farms and platform policy evasion.
