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.

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.

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.

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.

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.

A Decade of Hacks

This week we stumble into Microsoft's own confusion about whether or not Microsoft's Security Essentials will continue receiving updates after January 14th. We look briefly at the year when Ransomware happened, we revisit the Avast and AVG Mozilla extensions to see how they're doing, we look at the just-announced big news for Apple's and Google's bug bounty programs for 2020, and also at Mozilla's addition of another very appealing DoH provider (which Leo apparently likes). We provide a nudge to Drupal site masters to update their Drupal Cores RIGHT NOW... And then we conclude by revisiting this past decade -- spanning 2010 to 2019 -- and the many hacks we've explored during these previous ten years.

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.

Hide Your RDP Now!

This week we start off with something bad that we unfortunately saw coming. 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.

Bug Bounty Business

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.

Exim Under Siege

There were several significant stories this week. We have a new DRAM problem called "RAMBleed," news of a Linux server kernel-crashing flaw in TCP, and the occurrence of the expected attacks on Exim email servers - not to mention last week's Patch Tuesday, a Bluetooth surprise, and another useless warning about the BlueKeep vulnerability. 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!

Update Exim Now!

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.

The Nansh0u Campaign

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.

CPU.fail

As expected after last week's Tuesday morning end-of-embargo on details of the next round of Intel processor information leakage problems, we will take a closer look at the new challenges they create and the impact of their remediation on system performance and stability. 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.

Credential Stuffing Attacks

This week we look at more privacy fallout from our recent coverage of Facebook and Google. We examine the uptake rate of recent Windows 10 feature releases. 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 also look at Russia's newly approved legislation moving toward an Internet "off switch," a reminder that "USB Killers" are a real thing, the news of Marcus Hutchins's plea deal, an actively exploited Windows zero-day, a bunch of Microsoft Edge news, the Win7 end-of-life notices, something from the "I did say this was bound to happen" department, and some miscellaneous news. Then we examine the latest detailed threat research from Cisco's Talos Group about the leveraging of DNSpionage.

We touch on a bit of miscellany, answer a SpinRite upgrade question, and share some closing-the-loop feedback from our listeners. We close with a look at Dragonblood, the first effective attack on the new WPA3 protocol (which didn't take long).
