Our weekly audio security column & podcast by Steve Gibson and Leo Laporte

TechTV's Leo Laporte and I spend somewhat shy of two hours each week to discuss important issues of personal computer security. Sometimes we'll discuss something that just happened. Sometimes we'll talk about long-standing problems, concerns, or solutions. Either way, every week we endeavor to produce something interesting and important for every personal computer user.

Episode #799 | 29 Dec 2020 | 96 min.

SunBurst & SuperNova This week, as we end 2020, we look at Chrome's backing away from a security initiative, Firefox's move to further thwart tracking, all of the browsers once again saying “No!” to Kazakhstan, the formation of a new industry-wide Ransomware Task Force, this week's widespread WordPress security disaster, the return of Treck's insecure embedded TCP/IP stack, and yes... finally, the long awaited announcement of the release of the ReadSpeed benchmark which serves as a testbed and proof-of-operation for the next generation of SpinRite. And then we look at everything more that has come to light three weeks downstream from the first revelations of the SolarWinds-based massively widespread network intrusion and compromise.

SolarWinds This week is crammed with news leading up to our holiday break. Chrome is throttling ads. There's new cross-browser as insertion malware. We have a new term in the ransomware world. We have last week's Patch Tuesday, a jaw-dropping policy leak from Microsoft, trouble for Cisco's Jabber, an embarrassing vulnerability in many D-Link VPN servers, the brief Google outage, more horrific news of IoT network stack vulnerabilities, another WordPress mess, the 2020 Pwnie Awards, the welcome end-of-life of Flash, JavaScript's 25th birthday and free instruction classes, a bit of closing the loop, and SpinRite news. Then we take a full reconnaissance dive into what happened with the monumental and in so many ways horrific SolarWinds supply chain security breach.

Amazon Sidewalk At the beginning of this podcast, you're going to receive some details about another update to Chrome, and news of a few new high-profile ransomware victims. You'll learn about a breathtaking, remotely exploitable zero-click complete iPhone security compromise, as well as another significant big step forward for DNS privacy beyond DoH. We'll explain the nature of another serious and probably lingering problem within many Android apps. I have a few interesting bits of miscellany and SpinRite news to share. And before this is over, you will have obtained a full working sense for exactly what it is that Amazon has created and why, with their Amazon Sidewalk neighborhood IoT network concept, coming soon to all of your Amazon devices.

DNS Consolidation This week we look at a couple of new and forthcoming Chrome features. I'll quickly run though some new and notable ransomware casualties, including a couple of follow-ups. We'll look at a critical flaw in the Drupal content management system, the big trouble with generic smart doorbells, an interesting attack on Tesla Model X key fobs, CA's adaptation to single-year browser certs, several instances of leaked credential archives, a critical RCE in a major MDM server, a bit about the Salvation Trilogy, and some extremely promising news about SpinRite's future. Then we'll wrap up by taking a look at the consequences of the increasing consolidation of DNS service providers. It's not good if staying on the Internet is important to you.

Cicada This week we have a bunch of news on both the Chrome and Firefox fronts with patches, updates, and new features. We have a comical bit of news from the ransomware front, and more troubling ongoing WordPress attack specifics, including a weird eCommerce site spoofing attack. We look at the future consequences of ongoing vulnerability announcements coupled with their very incomplete patching, and Android's bold move right into the middle of the unbreakable end-to-end encryption controversy. And then we'll conclude with a look at a large, multiyear (as in 11-year) advanced very-persistent threat state-based attack perpetrator known as "Cicada."

SAD DNS This week the Chrome zero-days just keep on coming, and we contemplate what it means for the future. We have two interesting bits of ransomware meta news including a new tactic. We update after last week's Super Tuesday patch marathon, and examine new research into the most common source of Android malware to see where most unwanted apps come from and it's not what we would likely guess. We'll share a bit of listener feedback and an update on my work on SpinRite. Then we look at the new "SAD DNS" attack which successfully regresses us 12 years in DNS cache poisoning and spoofing attack prevention.

The 25 Most Attacked Vulnerabilities This week we examine a recently patched zero-day in Chrome and a nice new feature in that browser. We look at the site isolation coming soon to Firefox, and Microsoft's announcement of Edge for Linux. We have some movement in the further deprecation of Internet Explorer, and a potentially massive SQL injection attack that was recently dodged by more than one million WordPress sites, despite the fact that some admins complained. Then we have a bit of miscellany, closing-the-loop feedback, and an update on my work on SpinRite. We end by looking at the NSA's recently published list of the top 25 network vulnerabilities being used by malicious Chinese state actors to attack U.S. assets.

Well-Known URIs This week we catch up with Chrome 86's handful of security-related improvements. We touch on several recent ransomware events and on the consequences of not logging free WiFi users in France. We look at the results of an amazing bit of hacking of Apple, give an update on the enduring Zerologon threat, introduce the revenge of DNT with legislation-enhanced GPC, and describe another renewed attack on undecryptable E2EE now by seven countries. Then, following a bit of SpinRite and GRC forum news, we're going to add the concept of IANA-registered well-known URIs to our bag-of-tricks knowledgebase.

ZeroLogon++ This week we look back at the just-released Chrome 85. We see that an enterprise's choice of VPN gateway really does make a difference. We drop in for an update on what would have to be called the new ransomware gold rush, and we examine the implications of Ring's latest announcement of their flying spy drone I mean webcam. Then we learn how much Vitamin D Dr. Fauci takes, and invite our podcast listeners to lock down their UserID of choice at GRC's new web forums using a non-public URL. Then we conclude with the required big update to the Zerologon story which we began last week.

I Know What You Did Last Summer This week we take some deeper dives into fewer topics. We look at a bunch of the new features offered by Chrome's latest update, we look into the fascinating details of a Russian attempt to co-opt and bribe an employee of Tesla, and at some sobering security research which successfully circumvents VISA's point of sale PIN protection, allowing purchases of any amount. We also have a bunch of closing-the-loop feedback and miscellany. Then we examine the surprising research into just how well knowing where our browser has gone in the past identifies who we are today. Knowing what someone did last summer tells us who they are with surprising accuracy.

We look at a slick new privacy feature coming to iOS 14 and how it is already cleaning up prior behavior. We'll take our annual survey of the rapidly growing success of the HackerOne program, and also note the addition of a major new participant in their bug bounty management program. We briefly note the latest American city to ban the use of facial recognition for law enforcement, but we mostly examine the result of NIST's analysis of demographic bias in facial recognition outcomes. We'll also look at a high-velocity vulnerability and exploitation, and close the loop with a couple of listeners. I'll share an interesting bit of work on SpinRite's AHCI controller benchmarking. Then we'll look at this episode's mysterious title: "123456."

Contact Tracing Apps R.I.P. This week we begin with some browser news to examine a nifty new trick to be offered by the next Firefox 77 and we spend a bunch of time on the many new features -- and how to enable them -- being offered in Chrome's 83rd edition. We also look at Adobe's four emergency out-of-cycle patches, and a surprisingly robust and well designed new Jailbreak for iPhones. We take a look at a surprisingly powerful DNS amplification attack with a packet count multiplier of up to 1620, the sad but true complete collapse of Bluetooth connection security and the odd report of eBay scanning their user's PC's. We'll then share a bit of closing the loop listener feedback and a quick bit of miscellany, then I'm going to editorialize a bit about why I'm very sure that contact tracking apps are dead on arrival.

WiFi 6 We begin this week as we often do on the third Tuesday with a look at the previous week's Patch Tuesday; and, in this case, a troubling new trend is emerging. We look at the DoH support coming soon to Windows 10, and at a little known packet capture utility that was quietly added to Windows 10 with the October 2018 feature update. We'll spend a bit of time on yesterday's DOJ/FBI press conference, and then take a look at a problem that Microsoft appears to be having a surprising time resolving. We'll take a look at face masks thwarting automated public facial recognition, and Utah's decision to roll their own contact tracing and locating app. And we'll wind up with what I hope will be an interesting walk through the history of Ethernet, from the beginning of wired to the evolution of the many confusing wireless protocols.

Virus Contact Tracing This week we follow-up on a bunch of continuing Zoom news, since Zoom appears to be poised to become the teleconferencing platform of choice for the world at large. They've made more changes, have been sued and have been rapidly taking steps to fix their remaining problems. We have some browser news and another worrisome look into Android apps using a novel approach to quickly characterize them. We have an interesting and sad bit of miscellany and a progress report on my SpinRite work, and then we take the sort of full technical deep dive into the joint Apple/Google Contact Tracing system that our listeners have come to expect from this podcast. By the end of this podcast everyone will understand exactly what Apple and Google have done and how the system functions, in detail.

Zoom Go Boom! This week starts off with a bunch of web browser news including Firefox zero-days, Safari's recent scrape, more coronavirus-related feature rollbacks, the status of TLS v1.0 and 1.1, and some interesting developments on the Edge front. We revisit the lingering STIR and SHAKEN telco protocol mess, then look at a new DNS-filtering add-on service from Cloudflare and at the growing influence of an Internet group hoping to tighten up the mess with BGP. After a quick update on my SpinRite project, we take a look at what's been going on with the security of Zoom, the suddenly chosen tool for hosting Internet virtual classrooms and meetings of all kinds.

Folding Proteins This week we examine some consequences of increased telecommuting with the use of RDP and VPNs skyrocketing, along with a new bug in iOS's handling of VPN connections. We look at Google's unrelenting quest to get the "www" out, and note some changes to Firefox and further revisions of browser release schedules. We take a deep dive into a very welcome forthcoming code security feature for Windows 10. We share an action item for users of OpenWRT routers, and the result of an audit of Cloudflare's privacy-enforcing DNS service. We divulge a few interesting bits of feedback and some SQRL and SpinRite miscellany, then finish by examining a new opportunity to donate our unused CPU cycles for help with COVID-19 research.

TRRespass This week we look at a new unpatched zero-day attack affecting billions of Windows users, Mozilla's reversal on TLS 1.0 and 1.1 deprecation due to the coronavirus, a welcome micropatch for Win7 and Server 2008, Chrome's altered release schedule during the coronavirus, Avast's latest screw-up, a new threat affecting Android users, the results from last week's Pwn2Own competition, and a few observations about the coronavirus math and some worthwhile explainer videos. Then we look at where we are with Rowhammer after six years.

The SMBGHOST Fiasco This week we take a deep dive into the many repercussions preceding and following last week's Patch Tuesday. Wouldn't it be nice to have a quiet one for a change? But first, we look at a nice list of free services being maintained by BleepingComputer's Lawrence Abrams. We look at a recent report into the state of open source software vulnerabilities, and at new and truly despicable legislation aimed at forcing social media companies to provide "lawful access" to their customers' encrypted content.

The Fuzzy Bench This week we consider the new time-limited offers being made for free telecommuting tools, the continuing success of the DOD's "please come hack us" program, another take on the dilemma and reality of Android device security, some unwelcome news about AMD processor side-channel vulnerabilities, a new potentially serious and uncorrectable flaw in Intel processors, a 9.8-rated critical vulnerability in Linux system networking, a "stand back and watch the fireworks" forced termination of TLS v1.0 and v1.1, and the evolution of the SETI@home project after 19 years of distributed radio signal number crunching. We then touch on a bit of miscellany, and finish by looking at a new and open initiative launched by Google to uniformly benchmark the performance of security fuzzers.

Apple's Cert Surprise This week we reexamine the Windows 10 lost profiles problem, and also a consequence of the need to roll back (or avoid in the first place) the Patch Tuesday disaster. We look at a new feature to arrive with the next Windows 10 feature release, unfortunately named the 2004 release. We also examine the details of a new attack on the 4G LTE and 5G cellular technology, the full default rollout of Firefox's support for DoH, and also the availability of a powerful new sandboxing technology for Firefox. We also check in with Chrome's fix earlier today of a zero-day that was found being exploited in the wild. And, finally, before turning our attention to the bomb that Apple dropped in the lap of the entire certificate industry last week, I'm going to update our listeners about the things I've learned after returning to the work on SpinRite's next iteration.

The Internet of Troubles This week we continue following the continuing agony surrounding this month's increasingly troubled Window Update. We examine several significant failures which have befallen Windows 10 users after applying the month's "fixes," which have had the tendency of breaking things that weren't broken in the first place. We look at the danger presented by a very popular GDPR-compliance add-in for WordPress sites. We look at an eye-opening report about the stresses that CISOs are being subjected to, and also today's pilot test of Microsoft's new ElectionGuard voting system. We then touch on some SQRL and SpinRite news before taking a close look at two newly revealed IoT - Internet of Troubles - security worries.

Promiscuous Cookies This week we offer some welcome news about Microsoft A/V under Windows 7, we follow even more blow-by-blow consequences of January's final updates for Windows 7, we look at a worrisome exploitable Bluetooth bug Google just fixed in Android and what it means for those not fixed, we update on the ClearView AI face scanning saga, we take a peak into data recovery from physically destroyed phones, we entertain yet another whacky data exfiltration channel, and we conclude by looking at the consequences of the recent changes to make cookies mess promiscuous.

The Little Red Wagon This week we examine the most recent flaw found in Intel's processors and what it means. We look at the continually moving target that is Windows 10. We consider the Free Software Foundation's suggestion that Microsoft open source Windows 7 and the fact that last month's was apparently NOT the last update of Windows 7 for all non-ESU users. We look at the evolution of exploitation of the Remote Desktop Gateway flaw, Google's record breaking vulnerability bounty payouts, the return of Roskomnadzor, the size of fines, the question of who owns our biometrics, an update on Avast/AVG spying, the future of third-party AV, a major milestone for the WireGuard VPN, and the wonderful Little Red Wagon hack of the decade which titled this podcast.

SHAmbles This week we look at some surprising revelations of Apple's cloud storage encryption (or lack thereof). We also cover a Microsoft cloud database mistake, some interesting legislation under consideration in New York, new attacks against a consumer router firmware, a rise of new attacks against our browsers, a welcome new publication from NIST on Privacy, a massive leakage of telnet usernames and passwords, a welcome micropatch for this month's IE zero-day, a bit of miscellany and SpinRite news, and then some coverage of the final nail that was recently pounded into SHA-1's coffin.

Win 7 - R. I. P. This week's Security Now! podcast is titled "Windows 7 - R.I.P.," not because there's much that we haven't already said about the fact, but that it happens TODAY; and that, given the still massive install base of Windows 7, it's significant that all of those machines will now be going without any clearly needed security updates. So the big news for this week WAS to be the event of the first successful preimage attack on the SHA-1 hash. But that news was preempted at the last minute by the much more immediately significant news of the remotely exploitable "Cable Haunt" vulnerability that's present in most of the world's cable modems right now! So we'll be talking about that after we look at the FBI's recent request to have Apple unlock another terrorist's iPhone; update on the Checkrain jailbreak solution; examine the challenge of checking for illegal images while preserving privacy; look at some deeply worrying research into just how easy it is for bad guys to get SIMs swapped; examine the consequences of not patching a bad VPN flaw; deal with a bit of miscellany; and then, finally, look at the new "Cable Haunt" vulnerability.

A Malware Lexicon This first podcast of 2020 we look at a proposed standard for creating machine-readable warrant canaries. We also take a precautionary lesson from a big Xiaomi blunder, examine Microsoft's research into brute-forcing RDP, look at the continuing problem at the Point Of Sale, follow-up on Russia's plan to disconnect from the Internet, consider the end of life of Python 2.7, review the top 20 HackerOne bounty payers, warn of some bad new SQLite security vulnerabilities and cover a bit of Sci-Fi, SQRL and SpinRite miscellany. Then we group all malware into a seven-member Lexicon and quickly run through each one.
