Enlarge (credit: JAVS) A software maker serving more than 10,000 courtrooms throughout the world hosted an application update containing a hidden backdoor that maintained persistent communication with a malicious website, researchers reported Thursday, in the latest episode of a supply-chain attack. The software, known as the JAVS Viewer 8, is a component of the JAVS Suite 8, an application package courtrooms use to record, play back, and manage audio and video from proceedings. Its maker, Louisville, Kentucky-based Justice AV Solutions, says its products are used in more than 10,000 courtrooms throughout the US and 11 other countries. The company has been in business for 35 years. JAVS Viewer users at high risk Researchers from security firm Rapid7 reported that a version of the JAVS Viewer 8 available for download on javs.com contained a backdoor that gave an unknown threat actor persistent access to infected devices. The malicious download, planted inside an executable file that installs the JAVS Viewer version 8.3.7, was available no later than April 1, when a post on X (formerly Twitter) reported it. It’s unclear when the backdoored version was removed from the company’s download page. JAVS representatives didn’t immediately respond to questions sent by email.Read 10 remaining paragraphs | Comments

Enlarge (credit: Getty Images) Bing, Microsoft's search engine platform, went down in the very early morning today. That meant that searches from Microsoft's Edge browsers that had yet to change their default providers didn't work. It also meant that services relying on Bing's search API—Microsoft's own Copilot, ChatGPT search, Yahoo, Ecosia, and DuckDuckGo—similarly failed. Services were largely restored by the morning Eastern work hours, but the timing feels apt, concerning, or some combination of the two. Google, the consistently dominating search platform, just last week announced and debuted AI Overviews as a default addition to all searches. If you don't want an AI response but still want to use Google, you can hunt down the new "Web" option in a menu, or you can, per Ernie Smith, tack "&udm=14" onto your search or use Smith's own "Konami code" shortcut page. If dismay about AI's hallucinations, power draw, or pizza recipes concern you—along with perhaps broader Google issues involving privacy, tracking, news, SEO, or monopoly power—most of your other major options were brought down by a single API outage this morning. Moving past that kind of single point of vulnerability will take some work, both by the industry and by you, the person wondering if there's a real alternative.Read 11 remaining paragraphs | Comments

Enlarge For more than four days, a server at the very core of the Internet’s domain name system was out of sync with its 12 root server peers due to an unexplained glitch that could have caused stability and security problems worldwide. This server, maintained by Internet carrier Cogent Communications, is one of the 13 root servers that provision the Internet’s root zone, which sits at the top of the hierarchical distributed database known as the domain name system, or DNS. Here's a simplified recap of the way the domain name system works and how root servers fit in: When someone enters wikipedia.org in their browser, the servers handling the request first must translate the human-friendly domain name into an IP address. This is where the domain name system comes in. The first step in the DNS process is the browser queries the local stub resolver in the local operating system. The stub resolver forwards the query to a recursive resolver, which may be provided by the user's ISP or a service such as 1.1.1.1 or 8.8.8.8 from Cloudflare and Google, respectively.Read 15 remaining paragraphs | Comments

(credit: Benj Edwards) CAMBRIDGE, Massachusetts—On Wednesday, AI enthusiasts and experts gathered to hear a series of presentations about the state of AI at EmTech Digital 2024 on the Massachusetts Institute of Technology's campus. The event was hosted by the publication MIT Technology Review. The overall consensus is that generative AI is still in its very early stages—with policy, regulations, and social norms still being established—and its growth is likely to continue into the future. I was there to check the event out. MIT is the birthplace of many tech innovations—including the first action-oriented computer video game—among others, so it felt fitting to hear talks about the latest tech craze in the same building that hosts MIT's Media Lab on its sprawling and lush campus. EmTech's speakers included AI researchers, policy experts, critics, and company spokespeople. A corporate feel pervaded the event due to strategic sponsorships, but it was handled in a low-key way that matches the level-headed tech coverage coming out of MIT Technology Review. After each presentation, MIT Technology Review staff—such as Editor-in-Chief Mat Honan and Senior Reporter Melissa Heikkilä—did a brief sit-down interview with the speaker, pushing back on some points and emphasizing others. Then the speaker took a few audience questions if time allowed.Read 10 remaining paragraphs | Comments

Enlarge (credit: Getty Images) Malware recently spotted in the wild uses sophisticated measures to disable antivirus protections, destroy evidence of infection, and permanently infect machines with cryptocurrency-mining software, researchers said Tuesday. Key to making the unusually complex system of malware operate is a function in the main payload, named GhostEngine, that disables Microsoft Defender or any other antivirus or endpoint-protection software that may be running on the targeted computer. It also hides any evidence of compromise. “The first objective of the GhostEngine malware is to incapacitate endpoint security solutions and disable specific Windows event logs, such as Security and System logs, which record process creation and service registration,” said researchers from Elastic Security Labs, who discovered the attacks. When it first executes, GhostEngine scans machines for any EDR, or endpoint protection and response, software that may be running. If it finds any, it loads drivers known to contain vulnerabilities that allow attackers to gain access to the kernel, the core of all operating systems that’s heavily restricted to prevent tampering. One of the vulnerable drivers is an anti-rootkit file from Avast named aswArPots.sys. GhostEngine uses it to terminate the EDR security agent. A malicious file named smartscreen.exe then uses a driver from IObit named iobitunlockers.sys to delete the security agent binary.Read 10 remaining paragraphs | Comments

(credit: Microsoft) At a Build conference event on Monday, Microsoft revealed a new AI-powered feature called "Recall" for Copilot+ PCs that will allow Windows 11 users to search and retrieve their past activities on their PC. To make it work, Recall records everything users do on their PC, including activities in apps, communications in live meetings, and websites visited for research. Despite encryption and local storage, the new feature raises privacy concerns for certain Windows users. "Recall uses Copilot+ PC advanced processing capabilities to take images of your active screen every few seconds," Microsoft says on its website. "The snapshots are encrypted and saved on your PC’s hard drive. You can use Recall to locate the content you have viewed on your PC using search or on a timeline bar that allows you to scroll through your snapshots." By performing a Recall action, users can access a snapshot from a specific time period, providing context for the event or moment they are searching for. It also allows users to search through teleconference meetings they've participated in and videos watched using an AI-powered feature that transcribes and translates speech.Read 6 remaining paragraphs | Comments

Enlarge (credit: Benj Edwards | Getty Images) Since the launch of its latest AI language model, GPT-4o, OpenAI has found itself on the defensive over the past week due to a string of bad news, rumors, and ridicule circulating on traditional and social media. The negative attention is potentially a sign that OpenAI has entered a new level of public visibility—and is more prominently receiving pushback to its AI approach beyond tech pundits and government regulators. OpenAI's rough week started last Monday when the company previewed a flirty AI assistant with a voice seemingly inspired by Scarlett Johansson from the 2013 film Her. OpenAI CEO Sam Altman alluded to the film himself on X just before the event, and we had previously made that comparison with an earlier voice interface for ChatGPT that launched in September 2023. While that September update included a voice called "Sky" that some have said sounds like Johansson, it was GPT-4o's seemingly lifelike new conversational interface, complete with laughing and emotionally charged tonal shifts, that led to a widely circulated Daily Show segment ridiculing the demo for its perceived flirty nature. Next, a Saturday Night Live joke reinforced an implied connection to Johansson's voice.Read 11 remaining paragraphs | Comments

On Wednesday, the SEC adopted changes to Regulation S-P, which governs the treatment of the personal information of consumers. Under the amendments, institutions must notify individuals whose personal information was compromised “as soon as practicable, but not later than 30 days” after learning of unauthorized network access or use of customer data. The new requirements will be binding on broker-dealers (including funding portals), investment companies, registered investment advisers, and transfer agents. "Over the last 24 years, the nature, scale, and impact of data breaches has transformed substantially," SEC Chair Gary Gensler said. "These amendments to Regulation S-P will make critical updates to a rule first adopted in 2000 and help protect the privacy of customers’ financial data.

Nearly, that is, because the dogged researchers and enthusiasts at The Serial Port channel on YouTube have found what is likely the last existing copy of Archie. Archie, first crafted by Alan Emtage while a student at McGill University in Montreal, Quebec, allowed for the searching of various "anonymous" FTP servers around what was then a very small web of universities, researchers, and government and military nodes. It was groundbreaking; it was the first echo of the "anything, anywhere" Internet to come. And when The Serial Port went looking, it very much did not exist. The Serial Port's journey from wondering where the last Archie server was to hosting its own. While Archie would eventually be supplanted by Gopher, web portals, and search engines, it remains a useful way to index FTP sites and certainly should be preserved. The Serial Port did this, and the road to get there is remarkable and intriguing. You are best off watching the video of their rescue, along with its explanatory preamble. But I present here some notable bits of the tale, perhaps to tempt you into digging further.Read 4 remaining paragraphs | Comments

The site has operated for years as an online trading post where criminals could buy and sell all kinds of compromised data, including passwords, customer records, and other often-times sensitive data. Last week, a site user advertised the sale of Dell customer data that was obtained from a support portal, forcing the computer maker to issue a vague warning to those affected. Also last week, Europol confirmed to Bleeping Computer that some of its data had been exposed in a breach of one of its portals. The data was put up for sale on BreachForums, Bleeping Computer reported. On Wednesday, the normal BreachForums front page was replaced with one that proclaimed: “This website has been taken down by the FBI and DOJ with assistance from international partners.” It went on to say agents are analyzing the backend data and invited those with information about the site to contact them.

The unknown attackers behind the compromise infected at least four servers inside kernel.org, the Internet domain underpinning the sprawling Linux development and distribution network, the researchers from security firm ESET said. After obtaining the cryptographic hashes for 551 user accounts on the network, the attackers were able to convert half into plaintext passwords, likely through password-cracking techniques and the use of an advanced credential-stealing feature built into the malware. From there, the attackers used the servers to send spam and carry out other nefarious activities. The four servers were likely infected and disinfected at different times, with the last two being remediated at some point in 2011. Stealing kernel.org’s keys to the kingdom An infection of kernel.org came to light in 2011, when kernel maintainers revealed that 448 accounts had been compromised after attackers had somehow managed to gain unfettered, or “root,” system access to servers connected to the domain. Maintainers reneged on a promise to provide an autopsy of the hack, a decision that has limited the public’s understanding of the incident.Read 19 remaining paragraphs | Comments

(credit: Google) Just one day after OpenAI revealed GPT-4o, which it bills as being able to understand what's taking place in a video feed and converse about it, Google announced Project Astra, a research prototype that features similar video comprehension capabilities. It was announced by Google DeepMind CEO Demis Hassabis on Tuesday at the Google I/O conference keynote in Mountain View, California. Hassabis called Astra "a universal agent helpful in everyday life." During a demonstration, the research model showcased its capabilities by identifying sound-producing objects, providing creative alliterations, explaining code on a monitor, and locating misplaced items. The AI assistant also exhibited its potential in wearable devices, such as smart glasses, where it could analyze diagrams, suggest improvements, and generate witty responses to visual prompts. Google says that Astra uses the camera and microphone on a user's device to provide assistance in everyday life. By continuously processing and encoding video frames and speech input, Astra creates a timeline of events and caches the information for quick recall. The company says that this enables the AI to identify objects, answer questions, and remember things it has seen that are no longer in the camera's frame.Read 14 remaining paragraphs | Comments

The study (PDF), published this month by University of Chicago and University of Michigan researchers and reported by The Washington Post on Sunday, says: In this paper, we provide causal evidence that RTO mandates at three large tech companies—Microsoft, SpaceX, and Apple—had a negative effect on the tenure and seniority of their respective workforce. In particular, we find the strongest negative effects at the top of the respective distributions, implying a more pronounced exodus of relatively senior personnel. The study looked at résumé data from People Data Labs and used "260 million résumés matched to company data." It only examined three companies, but the report's authors noted that Apple, Microsoft, and SpaceX represent 30 percent of the tech industry's revenue and over 2 percent of the technology industry's workforce. The three companies have also been influential in setting RTO standards beyond their own companies. Robert Ployhart, a professor of business administration and management at the University of South Carolina and scholar at the Academy of Management, told the Post that despite the study being limited to three companies, its conclusions are a broader reflection of the effects of RTO policies in the US.Read 8 remaining paragraphs | Comments

Enlarge (credit: Getty Images) Google has updated its Chrome browser to patch a high-severity zero-day vulnerability that allows attackers to execute malicious code on end user devices. The fix marks the fifth time this year the company has updated the browser to protect users from an existing malicious exploit. The vulnerability, tracked as CVE-2024-4671, is a “use after free,” a class of bug that occurs in C-based programming languages. In these languages, developers must allocate memory space needed to run certain applications or operations. They do this by using “pointers” that store the memory addresses where the required data will reside. Because this space is finite, memory locations should be deallocated once the application or operation no longer needs it. Use-after-free bugs occur when the app or process fails to clear the pointer after freeing the memory location. In some cases, the pointer to the freed memory is used again and points to a new memory location storing malicious shellcode planted by an attacker’s exploit, a condition that will result in the execution of this code.Read 5 remaining paragraphs | Comments
