Redis, a tremendously popular tool for storing data in-memory rather than in a database, recently switched its licensing from an open source BSD license to both a Source Available License and a Server Side Public License (SSPL).

The software project and company supporting it were fairly clear in why they did this. Redis CEO Rowan Trollope wrote on March 20 that while Redis and volunteers sponsored the bulk of the project’s code development, “the majority of Redis’ commercial sales are channeled through the largest cloud service providers, who commoditize Redis’ investments and its open source community.” Clarifying a bit, “cloud service providers hosting Redis offerings will no longer be permitted to use the source code of Redis free of charge.”

Clarifying even further: Amazon Web Services (and lesser cloud giants), you cannot continue reselling Redis as a service as part of your $90 billion business without some kind of licensed contribution back.

Months after unbundling the apps in the European Union, Microsoft is taking the Office and Teams breakup worldwide. Reuters reports that Microsoft will begin selling Teams and the other Microsoft 365 apps to new commercial customers as separate products with separate price tags beginning today.

This is a win for other team communication apps like Slack and videoconferencing apps like Zoom, both of which predate Teams but haven’t had the benefits of the Office apps’ huge established user base.

The separation follows an EU regulatory investigation that started in July of 2023, almost exactly three years after Slack initially filed a complaint alleging that Microsoft was “abusing its market dominance to extinguish competition in breach of European Union competition law.”

On Friday, researchers revealed the discovery of a backdoor that was intentionally planted in xz Utils, an open-source data compression utility available on almost all installations of Linux and other Unix-like operating systems. The person or people behind this project likely spent years on it. They were likely very close to seeing the backdoor update merged into Debian and Red Hat, the two biggest distributions of Linux when an eagle-eyed software developer spotted something fishy.

“This might be the best executed supply chain attack we’ve seen described in the open, and it’s a nightmare scenario: malicious, competent, authorized upstream in a widely used library,” software and cryptography engineer Filippo Valsorda said of the effort, which came frightfully close to succeeding.

Researchers have spent the weekend gathering clues. Here’s what we know so far.

On Wednesday, the IEEE Computer Society announced to members that, after April 1, it would no longer accept papers that include a frequently used image of a 1972 Playboy model named Lena Forsén. The so-called “Lenna image,” (Forsén added an extra “n” to her name in her Playboy appearance to aid pronunciation) has been used in image processing research since 1973 and has attracted criticism for making some women feel unwelcome in the field.

In an email from the IEEE Computer Society sent to members on Wednesday, Technical & Conference Activities Vice President Terry Benzel wrote, “IEEE’s diversity statement and supporting policies such as the IEEE Code of Ethics speak to IEEE’s commitment to promoting an including and equitable culture that welcomes all. In alignment with this culture and with respect to the wishes of the subject of the image, Lena Forsén, IEEE will no longer accept submitted papers which include the ‘Lena image.'”

An uncropped version of the 512×512-pixel test image originally appeared as the centerfold picture for the December 1972 issue of Playboy Magazine. Usage of the Lenna image in image processing began in June or July 1973 when an assistant professor named Alexander Sawchuck and a graduate student at the University of Southern California Signal and Image Processing Institute scanned a square portion of the centerfold image with a primitive drum scanner, omitting nudity present in the original image. They scanned it for a colleague’s conference paper, and after that, others began to use the image as well.

Researchers have found a malicious backdoor in a compression tool that made its way into widely used Linux distributions, including those from Red Hat and Debian.

The compression utility, known as xz Utils, introduced the malicious code in versions ​​5.6.0 and 5.6.1, according to Andres Freund, the developer who discovered it. There are no confirmed reports of those versions being incorporated into any production releases for major Linux distributions, but both Red Hat and Debian reported that recently published beta releases used at least one of the backdoored versions—specifically, in Fedora 40 and Fedora Rawhide and Debian testing, unstable and experimental distributions.

Because the backdoor was discovered before the malicious versions of xz Utils were added to production versions of Linux, “it’s not really affecting anyone in the real world,” Will Dormann, a senior vulnerability analyst at security firm ANALYGENCE, said in an online interview. “BUT that’s only because it was discovered early due to bad actor sloppiness. Had it not been discovered, it would have been catastrophic to the world.”

Voice synthesis has come a long way since 1978’s Speak & Spell toy, which once wowed people with its state-of-the-art ability to read words aloud using an electronic voice. Now, using deep-learning AI models, software can create not only realistic-sounding voices, but also convincingly imitate existing voices using small samples of audio.

Along those lines, OpenAI just announced Voice Engine, a text-to-speech AI model for creating synthetic voices based on a 15-second segment of recorded audio. It has provided audio samples of the Voice Engine in action on its website.

Once a voice is cloned, a user can input text into the Voice Engine and get an AI-generated voice result. But OpenAI is not ready to widely release its technology yet. The company initially planned to launch a pilot program for developers to sign up for the Voice Engine API earlier this month. But after more consideration about ethical implications, the company decided to scale back its ambitions for now.

PyPI, a vital repository for open source developers, temporarily halted new project creation and new user registration following an onslaught of package uploads that executed malicious code on any device that installed them. Ten hours later, it lifted the suspension.

Short for the Python Package Index, PyPI is the go-to source for apps and code libraries written in the Python programming language. Fortune 500 corporations and independent developers alike rely on the repository for obtaining the latest versions of code needed to make their projects run. At a little after 7 pm Wednesday, California time, the site started displaying a banner message informing visitors that the site was temporarily suspending new project creation and new user registration. The message didn’t explain why or provide an estimate of when the suspension would be lifted.

About 10 hours later, PyPI restored new project creation and new user registration. Once again, the site provided no reason for the 10-hour halt.

The Snap Store, where containerized Snap apps are distributed for Ubuntu’s Linux distribution, has been attacked for months by fake crypto wallet uploads that seek to steal users’ currencies. As a result, engineers at Ubuntu’s parent firm are now manually reviewing apps uploaded to the store before they are available.

The move follows weeks of reporting by Alan Pope, a former Canonical/Ubuntu staffer on the Snapcraft team, who is still very active in the ecosystem. In February, Pope blogged about how one bitcoin investor lost nine bitcoins (about $490,000 at the time) by using an “Exodus Wallet” app from the Snap store. Exodus is a known cryptocurrency wallet, but this wallet was not from that entity. As detailed by one user wondering what happened on the Snapcraft forums, the wallet immediately transferred his entire balance to an unknown address after a 12-word recovery phrase was entered (which Exodus tells you on support pages never to do).

Pope takes pains to note that cryptocurrency is inherently fraught with loss risk. Still, Ubuntu’s App Center, which presents the Snap Store for desktop users, tagged the “Exodus” app as “Safe,” and the web version of the Snap Store describes Snaps as “safe to run.” While Ubuntu is describing apps as “Safe” in the sense of being an auto-updating container with runtime confinement (or “sandboxed”), a green checkmark with “Safe” next to it could be misread, especially by a newcomer to Ubuntu, Snaps, and Linux generally.

Broadcom has made sweeping changes to VMware’s business since acquiring the company in November 2023, killing off the perpetually licensed versions of VMware’s software and instituting large-scale layoffs. Broadcom executives have acknowledged the “unease” that all of these changes have created among VMware’s customers and partners but so far haven’t been interested in backtracking.

Among the casualties of the acquisition is the free version of VMware’s vSphere Hypervisor, also known as ESXi. ESXi is “bare-metal hypervisor” software, meaning that it allows users to run multiple operating systems on a single piece of hardware while still allowing those operating systems direct access to disks, GPUs, and other system resources.

One alternative to ESXi for home users and small organizations is Proxmox Virtual Environment, a Debian-based Linux operating system that provides broadly similar functionality and has the benefit of still being an actively developed product. To help jilted ESXi users, the Proxmox team has just added a new “integrated import wizard” to Proxmox that supports importing of ESXi VMs, easing the pain of migrating between platforms.

Thousands of servers storing AI workloads and network credentials have been hacked in an ongoing attack campaign targeting a reported vulnerability in Ray, a computing framework used by OpenAI, Uber, and Amazon.

The attacks, which have been active for at least seven months, have led to the tampering of AI models. They have also resulted in the compromise of network credentials, allowing access to internal networks and databases and tokens for accessing accounts on platforms including OpenAI, Hugging Face, Stripe, and Azure. Besides corrupting models and stealing credentials, attackers behind the campaign have installed cryptocurrency miners on compromised infrastructure, which typically provides massive amounts of computing power. Attackers have also installed reverse shells, which are text-based interfaces for remotely controlling servers.

Hitting the jackpot

“When attackers get their hands on a Ray production cluster, it is a jackpot,” researchers from Oligo, the security firm that spotted the attacks, wrote in a post. “Valuable company data plus remote code execution makes it easy to monetize attacks—all while remaining in the shadows, totally undetected (and, with static security tools, undetectable).”
