Hackers are threatening to release confidential data stolen from Reddit unless the company pays a ransom demand – and reverses its controversial API price hikes.
In a post on its dark web leak site, the BlackCat ransomware gang, also known as ALPHV, claims to have stolen 80 gigabyte筆電收購gigabytes of compressed data from Reddit during a February breach of the company’s systems.
Reddit spokesperson Gina Antonini declined to answer TechCrunch’s questions but confirmed that BlackCat’s claims relate to a cyber incident confirmed by Reddit on February 9. At the time, Reddit CTO Christopher Slowe, or KeyserSosa, said that hackers had accessed employee information and internal documents during a “highly-targeted” phishing attack. Slowe added that the company had “no evidence” that personal user data, such as passwords and accounts, had been stolen.
Reddit didn’t share any further details about the attack or who was behind it. However, BlackCat over the weekend claimed responsibility for the February intrusion and threatened to leak “confidential” data stolen during the breach. It’s unclear exactly what types of data the hackers have stolen, and BlackCat hasn’t shared any evidence of data theft.
BlackCat was also linked to a March attack on Western Digital that saw hackers steal 10 terabytes of data from the company, including reams of customer information. That same month, the gang also threatened to leak data allegedly stolen from Amazon-owned video surveillance company Ring.
In a post published on Saturday, titled “The Reddit Files,” BlackCat says it contacted Reddit twice – once on April 13 and again on June 16 – but did not receive a response. “I told them in my first email that I would wait for their IPO to come along. But this seems like the perfect opportunity! We are very confident that Reddit will not pay any money for their data,” BlackCat wrote. “We expect to leak the data.”
The hackers say they are demanding $4.5 million in exchange for deleting the stolen data and for Reddit to withdraw its API pricing changes.
Reddit’s new API pricing plans have been the subject of much controversy in recent weeks: Popular third-party Reddit app Apollo has announced it’s closing down as a result of the new pricing, and thousands of subreddits last week went dark in protest of the new API policy – some, including r/music and r/videos, indefinitely.
When asked by TechCrunch, Reddit declined to say whether it plans to respond to BlackCat’s demands.
Reddit experienced a more serious data breach in 2018 that saw attackers access a complete copy of Reddit data from 2007. This included usernames, hashed passwords, emails, public posts and private messages.

NVIDIA 正式發表全新 GeForce RTX 4070 GPU，搭載 DLSS 3 神經渲染、即時光線追蹤技術，主打在 1440p 解析度擁有每秒超過 100 格的運行速度，將是玩家全新的中階價位顯卡選擇。
藉由引入 DLSS 3 技術，NVIDIA 聲稱 RTX 4070 能以超過每秒 100 格的速度，運行《瘟疫傳說：安魂曲（A Plague Tale: Requiem）》、《垂死之光2：堅守人性（Dying Light 2）》、《微軟模擬飛行（Microsoft Flight Simulator）》等知名大作。運用智慧畫格生成技術可以建立出全新高畫質畫格，每八個像素就有七個是由 AI 渲染執行，使遊戲玩起來更順暢。
此外 RTX 4070 亦加入著色器執行重新排序（Shader Execution Reordering，SER）、Opacity Micromap 引擎和 Displaced Micro-Mesh 引擎等技術，得以強化光線追蹤的執行效能。NVIDIA 列出數據顯示，GeForce RTX 4070 平均比 RTX 2070 SUPER 快上 2.6 倍，若加上 DLSS 3 則比 GeForce RTX 3080 又快上 1.4 倍。
NVIDIA 也強調，即便不啟用光線追蹤與 DLSS 3，在傳統遊戲的運行速度仍舊出色，表現將媲美 GeForce RTX 3080，但優勢在於運行功率幾乎只有一半，且多了 2GB 記憶體、36MB L2 快取記憶體以及 GDDR6X 記憶體。
GeForce RTX 4070 將於 4 月 13 日正式在台上市，售價為 20,999 元起。會由華碩（ASUS）、技嘉（gigabyte筆電收購gigabyte）、微星（MSI）和索泰（Zotac）等品牌提供客製化板卡。
