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.

(This was not our idea. It was created by a fan of the podcast using GIMP (similar to
Photoshop). But as a work of extreme image manipulation, it came out surprisingly well.)

Episode #741 | 19 Nov 2019 | 114 min.

This week we look back at November's Patch Tuesday while we count down to the impending end of patches for Windows 7 and Server 2008. We check in with CheckM8 and Checkra.in as the iOS bootrom exploit continues to mature. We look at GitHub's announcement launch of "GitHub Security Lab" to bring bounties and much stronger security focus to the open source community. We discuss a recent court ruling regarding U.S. border entry device searches. We cover yet another bad WhatsApp remote code execution vulnerability. We examine the impact of version 2 of ZombieLoad, the formation of the Bytecode Alliance, and a bit of media miscellany. Then we examine the impact of two Trusted Platform Module (TPM) failings, one which allows local key extraction, and a second that can be exploited remotely over a network.

Credential Delegation

This week we check in on the developments of the long-term, now working, full consumer jailbreak of iOS devices from the iPhone 4S through the iPhone X. We examine the strange case of the misbehaving transducer, catch up on the rapidly evolving exploitation of the BlueKeep vulnerability, check out Mozilla's rebuttal to Comcast's attack on DoH, examine the surprising state of web browser support for DoH, and remind Linux and BSD users to refresh their distros after an important flaw was disclosed in a widely used archive library. Then we take a deep dive into the operation of a newly announced forthcoming solution and standard for significantly improving TLS website certificate security known as "TLS Credential Delegation."

DoH & BlueKeep

This week we examine a widespread Windows breakage introduced by last month's patch Tuesday. We look at several things Google changed in their just-released Chrome 78, news from the Edge, the status of attacks on Intel chips, a new attack on publicly-exposed QNAP NAS devices, the significant risk of trusting managed service providers, the downside of apps for autos, and worries over Chinese made drones. We then finish by coming back to look at news on two other fronts: The escalating controversy over DNS-over-HTTPS (DoH) and the commencement of the long-awaited BlueKeep vulnerability attacks.

A Foregone Conclusion

This week we look at another collision created by third-party AV; a powerful new Windows Defender feature that's easy to have missed; a public database breach by someone who should know better; what's worse than having all your files encrypted?; a VERY nice-looking, fully encrypted and free email service engineered in privacy-respecting Germany; stats coming back from Firefox's newly enhanced tracking privacy protection; a new and very bad remote code execution vulnerability affecting Nginx web servers; and the planned introduction of RCS to replace SMS next year. We also have a piece of SQRL news and some miscellany. Then we look at the outcome of a recent appellate court decision which complicates the decision about whether using a password or a biometric is more "judgment proof."

Biometric Mess

This week we check in on the frenzy to turn CheckM8 into a consumer-friendly iOS jailbreak, on another instance of stealth steganography, on a number of changes to Firefox's URL display, and on the state of Microsoft's ElectionGuard open source voting system. We also look at a very serious flaw that was just found in Linux's Realtek WiFi driver and some welcome news from Yubico. We touch on a couple of miscellaneous media tidbits, then take a look at the ramifications of two recent biometric authentication failures and consider the challenges and inherent tradeoffs of biometric authentication.

This week we take a look at a sobering supply chain proof-of-concept attack, an update on the ongoing encryption debate, a blast-from-the-past password decryption, an intriguing security and privacy consequence of today's high-resolution consumer cameras, and the sad state of consumer security knowledge. OpenPGP gets a nice boost, Windows Defender gets Tamper Protection, and SQRL gets a very nice mention by Google's Cloud Security architects. We'll share a bit of sci-fi and fun miscellany, then conclude by examining the crucially important, widely available, and completely unpatchable Apple Boot ROM exploit known as "CheckM8."

The Joy of Sync

With this week's "The Joy of Sync" podcast, we focus upon the latest state-of-the-art secure solutions for cross-device, cross-location device synchronization. But before we delve into that abyss, we'll update on Mozilla's recently announced plans to gradually and carefully bring DNS-over-HTTPS to all Firefox users in the U.S. It turns out it's not quite the slam dunk that we might imagine. We'll also check in with the EFF to see what they think, and remind our listeners about the 100% free VPN offering coming from our friends at Cloudflare.

Top 25 Bug Classes

This week we look at the driver behind this summer's comeback in cryptocurrency mining. We also check out a managed security provider's summary of the biggest problems they encounter with their more than 4000 clients. We look at the revised and worrisome update after six years of SOHO router and NAS device security, and we suggest that everyone using Chrome go to Help > About. I found three notes about SpinRite that I'm not sure I ever shared, so I will. Then we conclude with the result of processing the massive CVE vulnerability database which reveals the top 25 most enduring classes of software bug impacting the security of our industry.

This week we continue following the DoH story, which we begin discussing two weeks from now as a result of a rip in the space-time continuum. We also look at recent changes to Chrome 77 and the forthcoming Chrome 78, the already compromised iOS 13.0, and Mozilla Firefox's new browser VPN offering. We take a look back at last Tuesday's Patch Tuesday, take note of Chrome's Remote Desktop feature, cover another serious Exim mail server problem, handle a bit of miscellany, and examine a serious vulnerability affecting essentially ALL smartphone users known as “Simjacker.”

The Ransomware Epidemic

Rather than looking at many small bits of news, this week we take longer looks at a few larger topics. We'll examine several pieces of welcome news from the bug bounty front. We also take a look at Google's Project Zero revelation of a comprehensive multiyear campaign aimed at iOS visitors to specific websites. Then we conclude with a distressingly large array of news from the ransomware front. We figure out how to pronounce Sodinokibi (so-dee'-no-kee-bee) and ponder the future of ransomware.

Next Gen Ad Privacy

This week we check in on Texas, and on the Kazakhstan government's attempt to be their own CA. How did that work out for them? We note a troubling increase in attacks on the open source software supply chain. Google's announced plans to add data breach notification to Chrome. We look at a surprising Apple iOS v12.4 regression (whoops!) and at another Microsoft RDP component in need of updating. I update our listeners on the state of SQRL (another of its documents is completed) and on SQRL presentations past and future. I share some news from my ongoing file sync journey. We conclude by looking at some very interesting and promising moves as browser-based advertising matures from the ad hoc mess it has always been into a privacy-respecting Internet citizen.

The KNOB Is Broken

This week we look at last week's monthly Patch Tuesday and its collision with third-party AV add-ons. We examine four years of Kaspersky unique web user tracking. We look again at Tavis Ormandy's discovery of the secret undocumented CTF protocol, wondering WTF is CTF? We note a new and devastating strategy in the ransomware battle which hit Texas last Friday. We also have the sad demise of Extended Validation certificates, the further removal of FTP support from web browsers, Google's campaign to still further reduce web certificate lifetimes, and Netflix's discovery of eight implementation flaws in the new HTTP/2 protocol. We'll cover a bit of miscellany, update on my file syncing journey, touch on SQRL news and SpinRite, then conclude with a look at the most recent attack on Bluetooth pairing negotiation which renders all Bluetooth associations vulnerable to a trivial attack.

We then look at the changing security indication feedback in browsers; the challenge of keeping browsers compatible with important but non-standards-compliant websites; the failure and repair of incognito browsing mode; the possibility of a forthcoming "super incognito mode" for Firefox; a new super-fast TLS stack written in the Rust programming language; Microsoft's promised open source release of their voting machine election software; and yet another widely deployed, exposed, and exploitable Internet server. We have a quick bit of miscellany and some terrific SQRL news. Then we look at a recent and quite sobering report from Sophos about attacks on exposed RDP servers.

Encrypting DNS

This week we cover a few bullet points from last Tuesday's monthly Windows patches, as well as some annoyance that the patches caused for Windows 7 users. We track some interesting ongoing ransomware news and look at the mixed blessing of fining companies for self-reporting breaches. We check out a survey of enterprise malware headaches, update some Mozilla/Firefox news, and examine yet another (and kind of obvious) way of exfiltrating information from a PC. We address a bit of errata, some miscellany, and closing-the-loop feedback with our listeners. We then conclude with a closer look at all the progress that's been occurring quietly with DNS encryption.

Gem Hack & Ghost Protocol

This week we stumble over a number of instances where technology appears to be colliding with the status quo. In any complex social system, individual and group interests are often complex and may be in opposition. So when new technology comes along to offer new capabilities, not everyone is going to be pleased. So this week we discuss some of the mounting tensions being created by connectivity, storage, and computation which are being combined to create many new capabilities. We look at the surprising backlash to Mozilla's privacy-enhancing DNS-over-HTTPS support, concerns over the use of facial recognition and automobile license plate scanners, and the future of satellite-based Internet services. We present some SQRL news and share a bunch of closing-the-loop feedback from our listeners. We then examine how a Ruby code repository was hacked and look at the U.K. GCHQ's proposal for adding "ghost" participants into private conversations.

Exposed Cloud Databases

This week we track further occurrences of ransomware in Florida and elsewhere. We check in on the state of the "going dark" anti-encryption debate. We look at a stunning new BlueKeep proof-of-concept demo produced by the guys at SophosLabs. We update some miscellany and present some closing-the-loop feedback from our terrific listeners. Then we examine the nature of the continuing problem of massive publicly exposed databases. In the third example of this just this week, we discover a prolific Chinese IoT manufacturer who is logging more than a million of their customers' devices into an exposed database of two-billion-plus records - which returns us to the dilemma we have with the utter lack of oversight and control over our own IoT devices, and the need to soberly reconsider what "IoT" stands for.

This week we check in on the state of last week's Linux TCP SACK kernel panic, examine two Mozilla zero-days which were being used against Coinbase and others, and note that performing a full factory reset of an IoT device may not be sufficient. We look at a very clever and elegant solution to OpenSSH key theft via Rowhammer attacks, share an update on the BlueKeep RDP vulnerability, and examine the cause of a three-hour widespread Internet outage yesterday morning. We discuss NASA's APT, which crawled in via a Raspberry Pi, the cost of paying versus not paying a ransomware ransom, and an update on Microsoft's Chromium-based Edge browser. Lastly, we handle a bit of listener feedback, then take a closer look at the state of the commercial bug bounty business.

Microsoft missed a 90-day Tavis Ormandy deadline. We have a good-news GandCrab wrap-up, Yubico's entropy mistake, a bit of post-announce SQRL news, and a favorite iOS security app. We selected as our title story the attacks on Exim mail servers so that we can talk about the other disasters, which are still pending, next week!

This week we catch up with the continuing antics of SandboxEscaper. We give an update on the status of the still-not-yet-widely-exploited BlueKeep vulnerability, and also look at a new botnet which is pounding on RDP servers (but not yet using BlueKeep). The FBI has issued an interesting advisory about not trusting secure sites just because they're secure, so we'll examine that. The popular VideoLAN player receives an important update thanks to an interesting source, Microsoft's Edge browser takes another step forward, and Mozilla reorganizes a bit. Then I'm going to share my must-have Utility of the Week, a just-released sci-fi movie on Netflix, and a bit of closing-the-loop feedback from the Twitterverse which resulted from my, as planned, first formal full release of SQRL. We'll close with a look at the critical need for anyone running the Exim mail server to update immediately.

This week we check in on the BlueKeep RDP vulnerability. We look at the planned shutdown of one of the, if not THE, most successful, if one can call it that, affiliate-based ransomware systems. We update you on the anti-robocalling problem and then look at the recent announcements by the Russian and Chinese militaries about their plans to move away from the Microsoft Windows OS. We also look at Apple's announcement yesterday of their forthcoming "Sign in with Apple" service, touch on the state of SQRL, and then share a bit of fun feedback from a listener. We finish by examining the interesting details behind a significant old-school persistent campaign, the Nansh0u campaign, apparently sourced from China, which has successfully compromised many tens of thousands of servers exposed to the Internet.

RDP: Really Do Patch

This week we primarily focus upon the almost certainly impending doom of the Internet, as the Windows Remote Desktop Protocol saga finishes out its second week with a great deal of news and new evidence-based expectation for the end of humanity as we have known it. Okay, well, maybe it won't be quite that dramatic, but it already makes last year's Meltdown and Spectre flaws seem quaint. But before we get to that, we take a look at the FIVE new zero-day exploits just dropped by SandboxEscaper, Google's discovery and confession of 14 years of cleartext password storage, Microsoft's just-released Win10 Feature Update 1903, Firefox's release 67, and some interesting new data about the prevalence of validly signed malware.

But before that we look at last Tuesday's patches from Microsoft, Adobe, and Apple. We examine a new big security problem for Cisco that even has stock analysts taking notice. We check in on the ongoing troubles with the cryptocurrency market, see what Johns Hopkins associate professor Matthew Green tweeted about the trouble with Google's Titan Bluetooth dongle, and deal with yet another monthly problem with Windows 10 updates. We touch on a bit of miscellany, then wrap up with a look at the new so-called Microarchitectural Data Sampling vulnerabilities.

We finally know the source of the AV troubles with the April Patch Tuesday updates. We look at the NIST's formal fuzzing development, consider the source of a massive and ongoing database data leak involving more than half of all American households, note that Windows Insiders are already finding that their systems won't update to the May 2019 feature update, and address the concerns of United Airlines passengers who have noticed and been understandably upset by seatback cameras pointing at them. Finally, we have the "Cranky Old Guy Tip of the Week," touch on a bit of miscellany, then take a look at what many in the security industry are watching with concern: the large and emerging threat of website credential stuffing attacks.

We have another early-warned Drupal vulnerability that has immediately come under attack in the wild, and a 19-year-old flaw in an obscure decompress for the "ACE" archive format, which until a few days ago WinRAR was supporting to its detriment. Microsoft reveals an abuse of HTTP/2 protocol which is DoSing its IIS servers. Mozilla faces a dilemma about a wannabe Certificate Authority, and they also send a worried letter to Australia. Microsoft's Edge browser is revealed to be secretly whitelisting 58 web domains which are allowed to bypass its "Click-to-Run" permission for FLASH.

How well does ransomware pay? We have an idea now. We talk about two iOS scam apps, a false positive Bing warning, progress on the DNS over HTTPS front, and rumors that Microsoft is abandoning their EdgeHTML engine in favor of Chromium. We also have a bit of miscellany, news of a cybersecurity-related Humble Book Bundle just in time for Christmas, and a bit of closing-the-loop feedback. Then we discuss some new research that reveals that it's possible to recover pieces of web browser page images that have been previously viewed.

Hackers and attackers apparently enjoyed their Thanksgiving, since this week we have very little news to report. But what we do have to discuss should be entertaining and engaging: Yesterday the U.S. Supreme Court heard Apple's argument about why a class action lawsuit against their monopoly App Store should not be allowed to proceed; Google and Mozilla are looking to remove support for FTP from their browsers; and from our "What could possibly go wrong?" department we have browsers asking for explicit permission to leave their sandboxes. We also have some interesting post-Troy Hunt "Are Passwords Immortal?" listener feedback from last week's topic. Then we will discuss the next step in the evolution of RowHammer attacks, which do, as Bruce Schneier once opined, only get better - or in this case worse.

We offer a very workable solution for unsupported Intel firmware upgrades for hostile environments. We look at a forthcoming Firefox breach alert feature. We cover the expected takeover of exposed Docker-offering servers. We note the recently announced successor to recently ratified HTTP/2. We cover a piece of errata, close the loop with some of our podcast listeners, then finish by considering the future of passwords using a thoughtful article written by Troy Hunt, a well-known Internet security figure and the creator of the popular HaveIBeenPwned web service, among others.

We ask our listeners to check two router ports to protect against a new botnet that's making the rounds. We look at another irresponsibly disclosed zero-day, this time in VirtualBox. We look at CloudFlare's release of a very cool app for iOS and Android. And, in perfect synchrony with this week's main topic, we note Microsoft's caution about the in-RAM vulnerabilities of the BitLocker whole-drive encryption. We also cover a bit of miscellany, we close the loop with our listeners, and then we take a deep dive into last week's worrisome revelation about the lack of true security being offered by today's Self-Encrypting SSD Drives.

This week a widely used embedded OS (FreeRTOS) is in the doghouse, as are at least eight D-Link routers which have serious problems most of which D-Link has stated will never be patched. We look at five new problems in Drupal 7 and 8, two of which are rated critical, trouble with Live Networks RTSP streaming server, still more trouble with the now-infamous Windows 10 Build 1809 feature update, and a long standing 0-day in the widely used and most popular plugin for jQuery. We then look at what can only be described as an embarrassing mistake in the open source libssh library, and we conclude by examining a fun recent hack and pose its solution to our audience as our Security Now! puzzler of the week!

STARTTLS Everywhere

This week we discuss another worrisome trend in malware, another fitness tracking mapping incident and mistake, something to warn our friends and family to ignore, the value of periodically auditing previously granted web app permissions, and when malware gets picky about the machines it infects. Another kind of well-meaning Coinhive service gets abused. What are the implications of D-Link losing control of its code-signing cert? There's some good news about Android apps. iOS v11.4.1 introduces "USB Restricted Mode," but is it? We've got a public service reminder about the need to wipe old thumb drives and memory cards.
