An anonymous reader quotes a report from 404 Media: Doublespeed, a startup backed by Andreessen Horowitz (a16z) that uses a phone farm to manage at least hundreds of AI-generated social media accounts and promote products has been hacked. The hack reveals what products the AI-generated accounts are promoting, often without the required disclosure that these are advertisements, and allowed the hacker to take control of more than 1,000 smartphones that power the company. The hacker, who asked for anonymity because he feared retaliation from the company, said he reported the vulnerability to Doublespeed on October 31. At the time of writing, the hacker said he still has access to the company's backend, including the phone farm itself.

"I could see the phones in use, which manager (the PCs controlling the phones) they had, which TikTok accounts they were assigned, proxies in use (and their passwords), and pending tasks. As well as the link to control devices for each manager," the hacker told me. "I could have used their phones for compute resources, or maybe spam. Even if they're just phones, there are around 1100 of them, with proxy access, for free. I think I could have used the linked accounts by puppeting the phones or adding tasks, but haven't tried."

As I reported in October, Doublespeed raised $1 million from a16z as part of its "Speedrun" accelerator program, "a fastpaced, 12-week startup program that guides founders through every critical stage of their growth." Doublespeed uses generative AI to flood social media with accounts and posts to promote certain products on behalf of its clients. Social media companies attempt to detect and remove this type of astroturfing for violating their inauthentic behavior policies, which is why Doublespeed uses a bank of phones to emulate the behavior of real users. So-called "click farms" or "phone farms" often use hundreds of mobile phones to fake online engagement of reviews for the same reason. [...] I've seen TikTok accounts operated by Doublespeed promote language learning apps, dating apps, a Bible app, supplements, and a massager.

An anonymous reader shares a report: Browser extensions with more than 8 million installs are harvesting complete and extended conversations from users' AI conversations and selling them for marketing purposes, according to data collected from the Google and Microsoft pages hosting them.

Security firm Koi discovered the eight extensions, which as of late Tuesday night remained available in both Google's and Microsoft's extension stores. Seven of them carry "Featured" badges, which are endorsements meant to signal that the companies have determined the extensions meet their quality standards. The free extensions provide functions such as VPN routing to safeguard online privacy and ad blocking for ad-free browsing. All provide assurances that user data remains anonymous and isnâ(TM)t shared for purposes other than their described use.

The conventional wisdom that English prose has gotten easier to read because sentences have gotten shorter is wrong, according to a new analysis published in Works in Progress by writer and Mercatus Center research fellow Henry Oliver. The real transformation happened centuries ago in the 1500s and 1600s when Bible translators like William Tyndale and Thomas Cranmer developed a "plain style" built on logical syntax rather than the older rhythmic, periodic structures inherited from medieval prose.

Oliver argues that much of what modern datasets measure as declining sentence length is actually just changing punctuation habits. Writers now use periods where earlier generations used colons and semicolons. One dataset shows semicolon usage dropped from one every 90 words in 1781 to one every 390 words today. The cognitive complexity of a paragraph often remains the same regardless of how it's punctuated. Even wildly popular modern books don't follow the "short sentences equal readable" formula. Oliver points to Onyx Storm, the 2025 fantasy novel that has sold tens of millions of copies, which opens with sentences of 24 and 30 words. The 30-word sentence has a subordinate clause twice as long as its main clause. The book reads easily not because sentences are short but because the language is plain and the syntax is logical.

Cisco's stock price touched $80.25 on Wednesday, finally eclipsing its dotcom-era peak of $80.06 set on March 27, 2000 -- when the networking giant briefly surpassed Microsoft to become the world's most valuable company. The journey back took 25 years, eight months and 13 days. The company's fundamentals improved dramatically over that period, of course. Revenues have nearly quintupled since 1999, profits have quadrupled, earnings per share have grown eightfold, and margins have remained healthy throughout. Investors who bought at the peak still lost money to inflation for a generation.

Cisco's trajectory draws obvious comparisons to Nvidia, today's dominant "picks and shovels" supplier for the AI boom. Nvidia trades at a price-to-earnings ratio above 45 and an enterprise value-to-sales ratio near 24. At its 2000 peak, Cisco traded at a P/E above 200 and EV/sales of 31.

As the battle over Warner Bros. Discovery grows, two Democratic lawmakers are warning that their party may try to block or unravel any acquisition by Paramount when it returns to power. Semafor: In a letter to the WBD board and Treasury Secretary Scott Bessent first shared with Semafor, Reps. Sam Liccardo (D-Calif.) and Ayanna Pressley (D-Mass.) said they were concerned about the national security risk of letting foreign entities control a large portion of the US entertainment and media industry.

They also hinted that a future Democratic Congress and administration could try to unravel any Paramount-WBD deal. "Future Congresses ... will review many of the decisions of the current Administration, and may recommend that regulators push for divestitures, which would undermine the strategic logic of this merger," they wrote. "We urge the Board to weigh these national security and regulatory liabilities in evaluating a transaction burdened by uncertain but potentially extensive mitigation obligations, foreign influence risks, or adverse regulatory action."
