Microsoft has revealed details about a new project it has been working on for Linux kernel. From a report: Named Integrity Policy Enforcement -- or IPE -- the project is a Linux security module (LSM). LSMs are optional add-ons for the Linux kernel that enable additional security features. According to a documentation page published on Monday, IPE is Microsoft's attempt to solve the code integrity problem for Linux -- an operating system the company broadly uses in its Azure cloud service. On Linux systems where IPE is enabled, system administrators can create a list of binaries that are allowed to execute and then add the verification attributes the kernel needs to check for each binary before allowing it to run. If binaries have been altered by an attacker, IPE can block the execution of the malicious code.

Firefox 75 includes a revamped address bar with significant search improvements, a few performance tweaks, and a handful of developer features. You can download Firefox 75 for desktop now from Firefox.com, and all existing users should be able to upgrade to it automatically. According to Mozilla, Firefox has about 250 million active users, making it a major platform for web developers to consider.

When the coronavirus crisis took hold, millions found themselves spending more time in their browsers as they learn and work from home. But the crisis is also impacting software developers. Google was forced to pause its Chrome releases, which typically arrive every six weeks. Ultimately, Chrome 81 was delayed, Chrome 82 is being skipped altogether, and Chrome 83 has been moved up a few weeks. Microsoft has followed suit with Edge's release schedule, consistent with Google's open source Chromium project, which both Chrome and Edge are based on. Mozilla wants to make clear it is not in the same boat. The company took an indirect jab at Google and Microsoft today, saying: "We've built empathy into our systems for handling difficult or unexpected circumstances. These strengths are what allow us to continue to make progress where some of our competitors have had to slow down or stop work."

Brian Krebs: In February, KrebsOnSecurity told the story of a private citizen auctioning off the dangerous domain corp.com for the starting price of $1.7 million. Domain experts called corp.com dangerous because years of testing showed whoever wields it would have access to an unending stream of passwords, email and other sensitive data from hundreds of thousands of Microsoft Windows PCs at major companies around the globe. This week, Microsoft agreed to buy the domain in a bid to keep it out of the hands of those who might abuse its awesome power.

Last week, traffic meant for more than 200 of the world's largest content delivery networks (CDNs) and cloud hosting providers was suspiciously redirected through Rostelecom, Russia's state-owned telecommunications provider. From a report: The incident affected more than 8,800 internet traffic routes from 200+ networks, and lasted for about an hour. Impacted companies are a who's who in the cloud and CDN market, including big names such as Google, Amazon, Facebook, Akamai, Cloudflare, GoDaddy, Digital Ocean, Joyent, LeaseWeb, Hetzner, and Linode.

Ernesto, writing for TorrentFreak: With help from iknowwhatyoudownload we looked at over 25 million logged BitTorrent connections on a single day last week. This reveals that more than two-thirds (68.6%) of these were using uTorrent's desktop version. The vast majority of these users were updated to the most recent 3.5.5 release, but dozens of older versions are in use as well. Although no longer officially supported, there are also hundreds of thousands of people who still use uTorrent for Mac.

The most popular Mac client, however, appears to be Transmission. This is a notable change compared to a decade ago when its market share was much lower. Although Transmission also has a beta Windows release, that userbase is believed to be relatively small. Below is an overview of all software with at least 0.1% market share -- which translates to roughly 25,000 logged connections.

After many schools adopted Zoom to conduct online lessons during the coronavirus lockdown, concerns about security and privacy have led to a ban on the video conferencing software across the U.S. BetaNews reports: The chancellor of New York City's Department of Education Richard A Carranza sent an email to school principals telling them to "cease using Zoom as soon as possible." And he is not alone; schools in other parts of the country have taken similar action, and educators are now being trained to use Microsoft Teams as this has been suggested as a suitable alternative, partly because it is compliant with FERPA (Family Educational Rights and Privacy Act).

Documents seen by Chalkbeat show that principals in NYC have been told: "Based on the DOE's review of those documented concerns, the DOE will no longer permit the use of Zoom at this time." The Washington Post quotes Danielle Filson, spokesperson for the NYC Education Department, as saying: "Providing a safe and secure remote learning experience for our students is essential, and upon further review of security concerns, schools should move away from using Zoom as soon as possible. There are many new components to remote learning, and we are making real-time decisions in the best interest of our staff and student. We will support staff and students in transitioning to different platforms such as Microsoft Teams that have the same capabilities with appropriate security measures in place." Clark County Public Schools in Nevada, as well as schools in Utah, Washington State and beyond are looking into Zoom alternatives.

An anonymous reader quotes a report from Motherboard: Several major apps and websites, such as Paypal and Venmo have a flaw that lets hackers easily take over users' accounts once they have taken control of the victim's phone number. Earlier this year, researchers at Princeton University found 17 major companies, among them Amazon, Paypal, Venmo, Blizzard, Adobe, eBay, Snapchat, and Yahoo, allowed users to reset their passwords via text message sent to a phone number associated with their accounts. This means that if a hacker takes control of a victim's cellphone number via a common and tragically easy to perform hack known as SIM swapping, they can then hack into the victim's online accounts with these apps and websites.

Last week, two months after their initial outreach to the companies to report this flaw in their authentication mechanisms, the Princeton researchers checked again to see if the companies had fixed the problem. Some, including Adobe, Blizzard, Ebay, Microsoft, and Snapchat, have plugged the hole. Others have yet to do it. Paypal and Venmo, given that they are apps that allow users to exchange money and are linked to bank accounts or credit cards, may be the most glaring examples. Motherboard verified this week that it's possible to reset passwords on Paypal and Venmo via text message. Fear not, there is a solution. "The easiest way to make it impossible for SIM swappers to take over your accounts after they hijack your number is to unlink your phone number with those accounts, and use a VoIP number -- such as Google Voice, Skype, or another -- instead," reports Motherboard. "Google Voice numbers, given that they're not actually linked to a real SIM card, are much harder to hijack."

A sizeable number of Mac users are experiencing occasional system crashes after updating to macOS Catalina version 10.15.4, released a few weeks ago. From a report: The crashing issue appears to be most prominent when users attempt to make large file transfers. In a forum post, SoftRAID described the issue as a bug and said that it is working with Apple engineers on a fix for macOS 10.15.5, or a workaround. "SoftRAID said the issue extends to Apple-formatted disks: There is a serious issue with 10.15.4. It shows up in different scenarios, even on Apple disks but is more likely when there are lots of IO threads. We think it is a threading issue. So while SoftRAID volumes are hit the hardest (it's now hard to copy more than 30GB of data at a time), all systems are impacted by this. In our bug report to Apple, we used a method to reproduce the problem with ONLY Apple formatted disks. Takes longer to reproduce, but that is more likely to get a faster fix to the user base."

What happens when no one shows up for a tech conference?

Fast Company's technology editor harrymcc writes: From Apple to Microsoft to Google, major tech companies have responded to the coronavirus crisis by either canceling their 2020 conference or making them purely virtual. But one well-established event — Vancouver's CanSecWest — went ahead earlier this month, with streaming as an option but not mandatory. Only three attendees showed up in the flesh. But so did security reporter Seth Rosenblatt, who wrote about the eerie experience for Fast Company.
They were outnumbed by the six staffers at the event -- "there to run the online component" -- but the article notes that the conference's organizer and founder promised all attendees "infrared body temperature checks, on-site coronavirus testing, ample supplies of disposable face masks and hand sanitizer, and restrictions on physical contact and interaction..."

"Empty hallways and escalators echoed with every footstep, and it smelled empty, the ventilation system circulating unused air. At the conference registration desk, I was offered a disposable surgical face mask and gloves."

"In December, security researchers noticed an uptick in brute-force attacks against publicly exposed Microsoft SQL servers," reports CSOnline.

"It turns out the attacks go as far back as May 2018 and infect on average a couple thousand database servers every day with remote access Trojans and cryptominers."

Slashdot reader itwbennett writes: While the primary goal of the attack seems to be cryptocurrency mining, "what makes these database servers appealing for attackers apart from their valuable CPU power is the huge amount of data they hold," say researchers from Guardicore who investigated the attacks. The researchers also note that most machines (60%) stay infected only briefly, but "almost 20% of all breached servers remained infected for more than a week and even longer than two weeks," and 10% become reinfected...

[T]he attackers aggressively remove malware from competitors from targeted machines.
Many of the infected machines are located in America, India, South Korea, and Turkey, according to the article, which adds that the researchers traced the campaign back to China.

"The scans and attacks originate from Chinese IP addresses -- likely associated with infected and hijacked machines -- and the command-and-control servers are also hosted in China and use Chinese language for their web-based management interfaces."

Part of America's Department of Homeland Security, the Cybersecurity and Infrastructure Security Agency (CISA) "has advised users to update Google Chrome as new high-rated security vulnerabilities have been found," reports Forbes: In an April 1 posting, CISA confirmed that Google Chrome version 80.0.3987.162 "addresses vulnerabilities that an attacker could exploit to take control of an affected system," be that Windows, Mac or Linux. It went on to state that it "encourages" users and administrators to apply the update. It's not just CISA that is warning about the need to update Google Chrome. The Center for Internet Security (CIS) is a non-profit entity that works to safeguard both private and public organizations against cyber threats. In a multi-state information sharing and analysis center (MS-ISAC) advisory, it has also warned of multiple vulnerabilities in Google Chrome.

The most severe of these could allow an attacker to achieve arbitrary code execution within the context of the browser... All it would take for an attacker to exploit the vulnerabilities is to get the user to visit, by way of a phishing attack or even redirection from a compromised site, a maliciously crafted web page.
Beside three high-rated vulnerabilities, Forbes reports that "a further five security vulnerabilities were discovered by the Google internal security team using a combination of internal audits and fuzzing."

Last week long-time tech pundit Robert Cringely predicted "the death of IT" in 2020 due to the widespread adoption of SD-WAN and SASE.

Now he's predicting "an even bigger bloodbath as IT employees at all levels are let go forever," including IT consultants and contractors. My IT labor death scenario now extends to process experts (generally consultants) being replaced with automation. In a software-defined network, whether that's SD-WAN or SASE, so much of what used to be getting discreet boxes to talk with one another over the network becomes a simple database adjustment. The objective, in case anyone forgets (as IT, itself, often does) is the improvement of the end-user experience, in this case through an automated process. With SD-WAN, for example, there are over 3,000 available Quality of Service metrics. You can say that Office 365 is a critical metric as just one example. Write a script to that effect into the SD-WAN database, deploy it globally with a keyclick and you are done...

It's slowly dawning on IBM [and its competitors] that they have to get rid of all those process experts and replace them with a few subject matter experts. Here's the big lesson: with SD-WAN and SASE the process no longer matters, so knowing the process (beyond a few silverbacks kept on just in case the world really does end) isn't good for business.
Cringely predicts the downgrading of corporate bonds will also put pressure on IBM and its competitors, perhaps ultimately leading to a sale or spin-off at IBM. "Either they sell the parts that don't make money, which is to say everything except Red Hat and mainframes, or they sell the whole darned thing, which is what I expect to happen."

With that he predicts thousands of layoffs or furloughs — and while the bond market puts IBM in a bigger bind, "this could apply in varying degrees to any IBM competitors."

An anonymous reader quotes a report from Wired: Apple has a well-earned reputation for security, but in recent years its Safari browser has had its share of missteps. This week, a security researcher publicly shared new findings about vulnerabilities that would have allowed an attacker to exploit three Safari bugs in succession and take over a target's webcam and microphone on iOS and macOS devices. Apple patched the vulnerabilities in January and March updates. But before the fixes, all a victim would have needed to do is click one malicious link and an attacker would have been able to spy on them remotely.

The bugs Pickren found all stem from seemingly minor oversights. For example, he discovered that Safari's list of the permissions a user has granted to websites treated all sorts of URL variations as being part of the same site, like https://www.example.com, http://example.com and fake://example.com. By "wiggling around," as Pickren puts it, he was able to generate specially crafted URLs that could work with scripts embedded in a malicious site to launch the bait-and-switch that would trick Safari. A hacker who tricked a victim into clicking their malicious link would be able to quietly launch the target's webcam and microphone to capture video, take photos, or record audio. And the attack would work on iPhones, iPads, and Macs alike. None of the flaws are in Apple's microphone and webcam protections themselves, or even in Safari's defenses that keep malicious sites from accessing the sensors. Instead, the attack surmounts all of these barriers just by generating a convincing disguise.

Zoom is making some much-needed changes to prevent "Zoombombing," a term used to describe when someone successfully invades a public or private meeting over the videoconferencing platform to broadcast shock videos, pornography, or other disruptive content. The act was recently mentioned on the Department of Justice's website, warning that users who engage in this sort of video hacking could face fines and possible imprisonment. TechCrunch reports: Starting April 5th, it will require passwords to enter calls via Meeting ID, as these may be guessed or reused. Meanwhile, it will change virtual waiting rooms to be on by default so hosts have to manually admit attendees. [...] Zoom CEO Eric Yuan apologized for the security failures this week and vowed changes. But at the time, the company merely said it would default to making screensharing host-only and keeping waiting rooms on for its K-12 education users. Clearly it determined that wasn't sufficient, so now waiting rooms are on by default for everyone.

Zoom communicated the changes to users via an email sent this afternoon that explains "we've chosen to enable passwords on your meetings and turn on Waiting Rooms by default as additional security enhancements to protect your privacy." The company also explained that "For meetings scheduled moving forward, the meeting password can be found in the invitation. For instant meetings, the password will be displayed in the Zoom client. The password can also be found in the meeting join URL." Some other precautions users can take include disabling file transfer, screensharing or rejoining by removed attendees.

Apple has brought its hardware microphone disconnect security feature to its latest iPads. From a report: The microphone disconnect security feature aims to make it far more difficult for hackers to use malware or a malicious app to eavesdrop on a device's surroundings. The feature was first introduced to Macs by way of Apple's T2 security chip last year. The security chip ensured that the microphone was physically disconnected from the device when the user shuts their MacBook lid. The idea goes that physically cutting off the microphone from the device prevents malware -- even with the highest level of âoerootâ device permissions -- from listening in to nearby conversations. Apple confirmed in a support guide that its newest iPads have the same feature. Any certified "Made for iPad" case that's attached and closed will trigger the hardware disconnect.

Meetings on Zoom, the increasingly popular video conferencing service, are encrypted using an algorithm with serious, well-known weaknesses, and sometimes using keys issued by servers in China, even when meeting participants are all in North America, according to researchers at the University of Toronto. From a report: The researchers also found that Zoom protects video and audio content using a home-grown encryption scheme, that there is a vulnerability in Zoom's "waiting room" feature, and that Zoom appears to have at least 700 employees in China spread across three subsidiaries. They conclude, in a report for the university's Citizen Lab -- widely followed in information security circles -- that Zoom's service is "not suited for secrets" and that it may be legally obligated to disclose encryption keys to Chinese authorities and "responsive to pressure" from them.

For the past two weeks, a hacker has been breaking into Elasticsearch servers that have been left open on the internet without a password and attempting to wipe their content, while also leaving the name of a cyber-security firm behind, trying to divert blame. From a report: According to security researcher John Wethington, one of the people who saw this campaign unfolding and who aided ZDNet in this report, the first intrusions began around March 24. The attacks appear to be carried with the help of an automated script that scans the internet for ElasticSearch systems left unprotected, connects to the databases, attempts to wipe their content, and then creates a new empty index called nightlionsecurity.com. The attacking script doesn't appear to work in all instances, though, as the nightlionsecurity.com index is also present in databases where the content has been left intact.

Social networking giant Twitter today disclosed a bug on its platform that impacted users who accessed their platform using Firefox browsers. From a report: According to Twitter, its platform stored private files inside the Firefox browser's cache -- a folder where websites store information and files temporarily. Twitter said that once users left their platform or logged off, the files would remain in the browser cache, allowing anyone to retrieve it. The company is now warning users who share workstations or used a public computer that some of their private files may still be present in the Firefox cache. Malware present on a system could also scrape and steal this data, if ever configured to do so.

The internet is rife with online communities where users can go and share Zoom conference codes and request that pranksters connect and hurl insults, play pornographic material, or make death threats against other participants -- in a practice called Zoom-bombing or a Zoom raid. From a report: ZDNet began tracking the tactic since mid-March when the term was first coined following a TechCrunch article. Ever since then, Zoom-bombing incidents have increased, as articles in major news outlets like the New York Times and the BBC have made the practice a favorite pastime for all the teenagers stuck in their homes during the current coronavirus (COVID-19) quarantines. From a niche prank that started on a derelict Discord channel, Zoom-bombing has now spread to enormous proportions -- being so rampant these days that the FBI sent a nationwide alert last week, urging companies, schools, and universities to take steps to secure their Zoom channels. But as Zoom-bombing became more popular, more pranksters wanted to join on the fun, and more users wanted their friends' Zoom meetings disrupted. And as the old saying goes; where there's a demand, there's always a supply. Over the course of the past week, the number of places on the public internet where you can request a zoom raid from a gang of bored teenagers has exploded.

A community effort to improve the internet's routing security has won the backing of some of the web's biggest names. From a report: Amazon, Google, Facebook, Microsoft, Akamai, and Netflix, among others, have signed up to the Mutually Agreed Norms for Routing Security (MANRS) group, in their roles as content delivery networks (CDNs) and cloud providers (CPs). MANRS's goal is to shore up the internet's lax security when it comes to routing people's connections around Earth. It is, essentially, depending on the circumstances, too easy for miscreants to hijack and redirect internet traffic from legit servers to malicious machines so that web browsing and other online activities can be snooped on or meddled with. This widespread issue is something that has become increasingly important in the past few years as the number and size of connectivity breakdowns and attacks on the global system have grown. Criminals and possibly government spies have realized the potential that exists in snatching people's internet traffic for surveillance, disruption, and theft. The MANRS group pushes four main approaches, two technical and two cultural: filtering, anti-spoofing, and then coordination and validation.
