Not just deprecated, but deleted: Google finally strips File Transfer Protocol code from Chrome browser

A death by a thousand cuts


The Chromium team has finally done it – File Transfer Protocol (FTP) support is not just deprecated, but stripped from the codebase in the latest stable build of the Chrome browser, version 95.

It has been a while coming. A lack of support for encrypted connections in Chrome's FTP implementation, coupled with a general disinterest from the majority of the browser's users, and more capable third-party alternatives being available has meant that the code has moved from deprecated to gone entirely.

Support for fetching document resources over FTP was stripped from Chrome 72, proxy support for FTP was removed in Chrome 76, and Chrome 86 introduced a flag to turn it off completely.

In between 76 and 86, Google tinkered with deprecation, backing away in the first half of 2020 in response to the pandemic and the workload faced by hardpressed IT crews. However, the writing was on the wall for the venerable protocol.

By version 88 it was disabled for all users, but still could be switched back on. Now the code to support it has at last been removed once and for all, a little later than hoped.

Mozilla dumped the protocol from its Firefox browser back in July, and Apple doesn't really support it in Safari.

As for Microsoft, while its Edge browser might be based on Chromium, there is always Internet Explorer, which should still do the business should you have a need for a bit of browser-based retro file-transfer action. And few browsers deserve the retro tag as much as IE, even if Microsoft is determined to kill it off in most forms next year.

As for why FTP has attracted such ire – well, the protocol is over 50 years old and comes from more innocent times, when authentication was not what it is today. More secure options now exist (such as FTPS and SFTP) and, frankly, Google and pals would rather users opted for a dedicated transfer app than bother maintaining the code in the browser.

There remain a good few FTP sites out there (such as the US Census Bureau), although many now have alternatives for file transfer. The final ejection of the code from Chrome, which lays claim to a huge userbase, means it really is time to move on. ®

  • It's 2022 and there are still malware-laden PDFs in emails exploiting bugs from 2017
    Crafty file names, encrypted malicious code, Office flaws – ah, it's like the Before Times

    HP's cybersecurity folks have uncovered an email campaign that ticks all the boxes: messages with a PDF attached that embeds a Word document that upon opening infects the victim's Windows PC with malware by exploiting a four-year-old code-execution vulnerability in Microsoft Office.

    Booby-trapping a PDF with a malicious Word document goes against the norm of the past 10 years, according to the HP Wolf Security researchers. For a decade, miscreants have preferred Office file formats, such as Word and Excel, to deliver malicious code rather than PDFs, as users are more used to getting and opening .docx and .xlsx files. About 45 percent of malware stopped by HP's threat intelligence team in the first quarter of the year leveraged Office formats.

    "The reasons are clear: users are familiar with these file types, the applications used to open them are ubiquitous, and they are suited to social engineering lures," Patrick Schläpfer, malware analyst at HP, explained in a write-up, adding that in this latest campaign, "the malware arrived in a PDF document – a format attackers less commonly use to infect PCs."

  • New audio server Pipewire coming to next version of Ubuntu
    What does that mean? Better latency and a replacement for PulseAudio

    The next release of Ubuntu, version 22.10 and codenamed Kinetic Kudu, will switch audio servers to the relatively new PipeWire.

    Don't panic. As J M Barrie said: "All of this has happened before, and it will all happen again." Fedora switched to PipeWire in version 34, over a year ago now. Users who aren't pro-level creators or editors of sound and music on Ubuntu may not notice the planned change.

    Currently, most editions of Ubuntu use the PulseAudio server, which it adopted in version 8.04 Hardy Heron, the company's second LTS release. (The Ubuntu Studio edition uses JACK instead.) Fedora 8 also switched to PulseAudio. Before PulseAudio became the standard, many distros used ESD, the Enlightened Sound Daemon, which came out of the Enlightenment project, best known for its desktop.

  • VMware claims 'bare-metal' performance on virtualized GPUs
    Is... is that why Broadcom wants to buy it?

    The future of high-performance computing will be virtualized, VMware's Uday Kurkure has told The Register.

    Kurkure, the lead engineer for VMware's performance engineering team, has spent the past five years working on ways to virtualize machine-learning workloads running on accelerators. Earlier this month his team reported "near or better than bare-metal performance" for Bidirectional Encoder Representations from Transformers (BERT) and Mask R-CNN — two popular machine-learning workloads — running on virtualized GPUs (vGPU) connected using Nvidia's NVLink interconnect.

    NVLink enables compute and memory resources to be shared across up to four GPUs over a high-bandwidth mesh fabric operating at 6.25GB/s per lane compared to PCIe 4.0's 2.5GB/s. The interconnect enabled Kurkure's team to pool 160GB of GPU memory from the Dell PowerEdge system's four 40GB Nvidia A100 SXM GPUs.

  • Nvidia promises annual updates across CPU, GPU, and DPU lines
    Arm one year, x86 the next, and always faster than a certain chip shop that still can't ship even one standalone GPU

    Computex Nvidia's push deeper into enterprise computing will see its practice of introducing a new GPU architecture every two years brought to its CPUs and data processing units (DPUs, aka SmartNICs).

    Speaking on the company's pre-recorded keynote released to coincide with the Computex exhibition in Taiwan this week, senior vice president for hardware engineering Brian Kelleher spoke of the company's "reputation for unmatched execution on silicon." That's language that needs to be considered in the context of Intel, an Nvidia rival, again delaying a planned entry to the discrete GPU market.

    "We will extend our execution excellence and give each of our chip architectures a two-year rhythm," Kelleher added.

  • Amazon puts 'creepy' AI cameras in UK delivery vans
    Big Bezos is watching you

    Amazon is reportedly installing AI-powered cameras in delivery vans to keep tabs on its drivers in the UK.

    The technology was first deployed, with numerous errors that reportedly denied drivers' bonuses after malfunctions, in the US. Last year, the internet giant produced a corporate video detailing how the cameras monitor drivers' driving behavior for safety reasons. The same system is now apparently being rolled out to vehicles in the UK. 

    Multiple camera lenses are placed under the front mirror. One is directed at the person behind the wheel, one is facing the road, and two are located on either side to provide a wider view. The cameras are monitored by software built by Netradyne, a computer-vision startup focused on driver safety. This code uses machine-learning algorithms to figure out what's going on in and around the vehicle.
