SN815: Homogeneity Attacks 21.04.2021

This week we touch on the Vivaldi browser project's take on Google's FLoC. We look at Chrome's vulnerability-driven update to v89, and then its feature-embellished move to Chrome 90. We consider the surprising move by the FBI to remove web shells from U.S. Exchange Servers without their owners' knowledge or permission, and WordPress's consideration of FLoC Blocking. We also have an interesting-loo...

SN814: PwnIt and OwnIt 14.04.2021

This week we start with some needed revisiting of previous major topics. We look at an additional remote port that Chrome will soon be blocking, and the need to change server ports if you're using it. We look again at Google's forthcoming FLoC non-tracking technology and a new test page put up by the EFF. We revisit the PHP GIT server hack now that it's been fully understood. We look at Cisco's ey...

SN813: A Spy in Our Pocket 07.04.2021

This week, by popular demand, we examine the big cover-up at Ubiquiti. We look at the consequences of the personal data of 533-plus million Facebook users appearing on the 'Net and how to tell if you're represented there. We look at another water treatment plant break-in with a very different outcome. We look at a new move by Google to further lock down Android against abuses of its permissive-by-...

SN812: GIT Me Some PHP! 31.03.2021

This week we begin by checking in on the patching progress, or lack therefore, of the ProxyLogon Exchange Server mess. We examine a new Spectre vulnerability in Linux, a handful of high-severity flaws affecting OpenSSL, still more problems surfacing with SolarWinds code, an intriguing new offering from our friends at Cloudflare, and the encouraging recognition of the need for increasing vigilance...

SN811: What the FLoC? 24.03.2021

This week we briefly, I promise, catch up with ProxyLogon news regarding Windows Defender and the Black Kingdom. We look at Firefox's next release which will be changing its Referer header policy for the better. We look at this week's most recent RCE disaster, a critical vulnerability in the open source MyBB forum software, and China's new CAID (China Anonymization ID). We then conclude by taking...

SN810: ProxyLogon 17.03.2021

This week we start off with a bunch of interesting browser-related news, zero-days, updates, a browser-based PoC for Spectre, a zero-script tracking kludge, and a look at last Tuesday's Patch Tuesday, what it fixed and what it broke. Some wonderful news for the Open Source community, a bit of miscellany, some listener feedback, and a screenshot of the final replacement for SpinRite's "Discovering...

SN809: Hafnium 10.03.2021

This week we look into last week's critical Chrome update and also cover the wackiest-but-true Chrome extension of all time. We look at Google's new funding of Linux security development; a surprisingly undead, long-unheard-from media player that just received a massive collection of updates; and, yes, still another way of abusing Intel's latest processor microarchitecture. We need to update every...

SN808: CNAME Collusion 03.03.2021

This week we discuss a welcome change coming soon to the Chrome browser, and a welcome evolution in last week's just released Firefox 86. We're going to look at questions surrounding the source of the original intrusion into SolarWinds servers, and at a new severity-10 vulnerability affecting Rockwell Automation PLC controllers. We'll touch on VMware's current trouble with exploitation of their vC...

SN807: Dependency Confusion 24.02.2021

This week we'll follow-up on the Android SHAREit app sale. We look at a clever new means of web browser identification and tracking and at a little mistake the Brave browser made that had big effect. I want to remind our listeners about the ubiquitous presence of tracking and viewing beacons in virtually all commercial eMail today. We'll look at Microsoft's final SolarWinds Solorigate report and a...

SN806: C.O.M.B. 17.02.2021

This week we'll begin by following up on last week's headline-making attack on the Oldsmar, Florida water treatment plant with new details that have since come to light. We'll then take a look into last week's Patch Tuesday event and at some of the sadly broken things that have once again been fixed. Also, anyone using Adobe's PDF tools, Acrobat or Reader, needs to update. We're going to look at a...

SN805: SCADA Scandal 10.02.2021

This week we begin with a collection of interesting and engaging news surrounding Google's Chrome browser. We look at a high-profile Windows Defender misfire, and at new WordPress plugin nightmares. We check in on the world of DDoS attacks and cover the meaning of three new critical vulnerabilities in SolarWinds software. We have a bit of closing-the-loop feedback from our listeners, an update on...

SN804: NAT Slipstreaming 2.0 03.02.2021

This week we examine another instance of a misbehaving certificate authority losing Chrome's trust. We cover a number of serious new vulnerabilities including an urgent update need for the just-released Gnu Privacy Guard; another supply chain attack against end users; a disastrous 10-year-old flaw in Linux's SUDO command; and, thanks to Google, some details of Apple's quietly redesigned sandboxing...

SN803: Comparative Smartphone Security 27.01.2021

This week we look at the updates in release 88 of both Chrome and Edge with their evolving password manager features. We also look at two recent headshaking consequences of the hard end of life for Adobe's Flash. Ransomware gangs have added another new incentive for payment, and additional details continue emerging about last year's SolarWinds attacks. We have newly disclosed discoveries from a Go...

SN802: Where the Plaintext Is 20.01.2021

This week we look at one aspect in which Chrome and Chromium differ, and then at a bit of growth news from the DuckDuckGo folks. Google's Project Zero reports on some terrific detective work, and we look at last week's Patch Tuesday. There's also Microsoft's pending change to the flaws which enabled last year's Zerologon debacle, and the NSA's interesting statement about enterprises and the DoH pr...

SN801: Out With the Old 13.01.2021

This week we address critical updates for Firefox and all Chromium-based browsers and a potentially unwelcome, but reversible, change coming to Firefox. We look at another new tactic being employed by ransomware gangs; an update on ransomware's profitability; a bogus-seeming announcement from Intel during yesterday's CES; and the first use, on this podcast, of the term "teledildonics." Following t...

SN800: SolarBlizzard 06.01.2021

This week we open the New Year taking a longer look at fewer topics since the bad guys were apparently enjoying their New Year holiday, too. So we look at an interesting kludge that's been forced upon Chrome by ill-mannered antiviral scanners. We need to warn all enterprise users of Zyxel network border security products of another recently discovered built-in backdoor. We look at the rise in IoT...

SN799: SunBurst & SuperNova 30.12.2020

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 announc...

SN798: The Best of 2020 23.12.2020

This week is our annual holiday best of the year wrap up.

SN797: SolarWinds 16.12.2020

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 net...

SN796: Amazon Sidewalk 09.12.2020

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 linge...

SN795: DNS Consolidation 02.12.2020

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 instance...

SN794: Cicada 26.11.2020

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 An...

SN793: SAD DNS 18.11.2020

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 sha...

SN792: "Slipstream" NAT Firewall Bypass 11.11.2020

This week we look at the dilemma of Let's Encrypt's coming root expiration, new Chrome and Apple zero-day vulnerabilities, some new high-profile ransomware victims, China's Tianfu Cup pwning competition, the retirement of a PC industry insider, the continuing Great Encryption Dilemma, police monitoring of consumers' video, more ongoing pain for WordPress, a note about a sci-fi book event one week...

SN791: Chrome's Root Program 04.11.2020

This week we examine a serious newly revealed Windows zero-day flaw, a public service reminder from Microsoft, Google's newly announced plan to get into the VPN service business, CERT's unappealing plan for automatic vulnerability naming, and a real mess that WordPress just made of an incremental security update to 455 million sites. Then we'll close a loop, I'll update about SpinRite, and we'll f...
