This Week In Security: Critical DNS Keys Rotated, Hacking Freezers Isn’t Cool, OpenAI Spies On Itself, And Advanced Hardware Wallet Hacks

October 16, 2026 by 12 Comments

Critical Internet keys changed this week. Did you notice?  The keys behind DNSSEC, the system for cryptographically validating DNS responses, rolled over on October 11 2026. This is the second time the DNSSEC keys have rotated since the system was implemented, and the first time in 2018 didn’t exactly go entirely smoothly.

DNS is what resolves a host name and turns it into an IP address. It underpins web browsing, email, and just about every other connection. It’s also a very early Internet protocol, written in both a simpler, less paranoid era, and an era where encryption was computationally expensive and legally problematic. DNS offers little protection against malicious actors spoofing responses, and the impacts range from phishing to redirecting email to just about any other manipulation of connections you can image.

DNSSEC addresses this by creating a chain of trust between DNS resolvers — the servers that forward the DNS query into the DNS infrastructure and return the results — and the global DNS servers. Part of this chain of trust is the root key that each resolver must have and trust, and this key is what changed this week.  DNSSEC resolvers automatically watch for a new root of trust key, but the key must be signed by the previous root of trust, and is checked for at least 30 days before it is trusted.  If someone were able to issue a bogus certificate, they would have to maintain control of the infrastructure for over a month before DNS resolvers would trust it.

The process of distributing the new key actually began more than a year ago, on January 11, 2025, to give DNSSEC resolvers time to get the new key. DNSSEC services should have had plenty of time to obtain and trust the new key, and unless DNS stopped working for you this week, they did their job.

The next major change for DNSSEC will require more profound changes to deploy a new signing algorithm that will be post-quantum secure.

This Week In Security: New Spectre Attacks, Crushing Quantity Of Linux Vulns, Google Gets Too Much AI, And Hacking Lawnmowers

October 9, 2026 by 11 Comments

Just-in-time, or JIT, compilation could be considered a fundamental backbone of modern computing.  JIT compilation turns scripting languages like JavaScript or intermediary binary forms like Web Assembly into native code on the fly, giving web apps, and things that are web apps under the covers like Electron-based tools, near native speed.  A new paper explores leveraging JIT systems to revive Spectre-v2 attacks against processors.

Most modern processors gain performance by using a trick called “speculative execution”.  The processor guesses the likely result of a compare, and begins executing some of the next instructions before the results are actually known.  If the processor guessed right, things continue and there is a speed gain because it can jump ahead, but if the processor guessed wrong, any instructions that were run and any side effects of running them are discarded and execution resumes on the actual path.  In theory, anyhow.

In practice, the Spectre class of attacks targets branch prediction. It was discovered that when the wrong branch was chosen, not all of the results were truly hidden; Patterns of failures in guessing branches can be used to leak behavior processing encryption keys and other activities. The attacks evolved with the research dubbed Spectre-V2, which showed that non-privileged contexts, like non-root users and virtual machines, could poison the instruction prediction and use it to read arbitrary memory.  Fixes to the Linux kernel and other platforms were required to mitigate the worst of the effects.

The paper shows that by using self-modifying code in the JIT, the processor can be tricked into loading cached versions of the instructions.  The fixes to the kernel to prevent Spectre attacks include identifying malicious code patterns that attack the branch prediction, and stopping or changing them:  By causing the CPU to execute the cached copy of instructions instead of the live copy, the attack ignores the fixed instructions entirely and can attack the branch prediction algorithm.

To prove the attack is feasible in the real world, the researchers targeted several JIT compilers, including the SpiderMonkey JavaScript engine used by Firefox, the eBPF JIT found in the Linux kernel, and GraalVM, the JIT used in Python.  They found success with each, demonstrating that the attack is at least plausible.

Research like this is unlikely to be an instant world-melter, and will help find possible mitigations in the future to prevent these sorts of attacks.  Operating systems that support a high-security “lock-down” mode, like macOS and iOS, often disable JIT entirely, out of concern about these sorts of attacks.  There’s probably no need to start disabling JIT on every system, but attacks like these have a tendency to evolve.

This Week In Security: ShinyHunters Won’t Dox The FBI, Pentagon Data Stolen, And OBS Vulnerable

October 2, 2026 by 7 Comments

404 Media reports that the ShinyHunters group who stole multiple terabytes of FBI employee data say they do not plan to release the data.

Known for ransomware and extortion of innumerable companies and government agencies, ShinyHunters used a zero-day vulnerability in Oracle PeopleSoft to compromise the employment site of the FBI and pivot into scraping the content of FBI AWS instances, claiming to have the full employment and health data of all FBI agents, employees, and spouses.

The hacker group took exception to an FBI press release that claimed that the group over-stated stolen data and that they directly harass victims and victim’s families.  The group publicized the FBI data breach, demanding a retraction of the statements, and it was generally assumed that the group would follow their typical methods of releasing the data publicly if the demands were not met.

The group has told 404 media that they had always agreed internally to not release the stolen data, saying “This was all a marketing campaign to protect our business and actively combat disinformation”.  Meanwhile the FBI continues the investigation, and Shiny Hunters may be hoping to defer some of the ire.

This Week In Security: FBI Gets Hacked, Muse Vulnerable To ClickFix, Popular Rust Developers At Risk, And New Attacks Against RSA

September 25, 2026 by 14 Comments

The prolific ShinyHunters group has announced it used a zero-day vulnerability in Oracle PeopleSoft to exploit the FBI jobs website and gain access to the AWS GovCloud instances and dump 2 TB of employee data. GovCloud being a special, locked-down version of the Amazon Web Services cloud for US government users.

ShinyHunters has previously been involved in dozens of high-profile hacks and ransomware incidents.  Some of the highest-profile incidents include Jaguar-Land Rover, causing a measurable impact on the UK GDP, Grubhub, Carnival Cruise Lines, Rockstar Games, and multiple universities and educational institutions, casinos, and other government agencies.  ShinyHunters has also been credited with the hack of the Canvas educational program in the spring of 2026 where data including test results and chat logs of hundreds of millions of students, teachers, and staff was stolen.  ShinyHunters has generally been identified as an international group of criminals, often teenagers, who will demand a BitCoin ransom of several million US dollars, with the threat of the stolen data being leaked if the victims do not pay.

On May 15, 2026 the FBI released a bulletin on the activities of ShinyHunters, focusing on the Canvas educational hack.  In the report, the FBI said that the group uses “harassment strategies, sending threatening text messages and phone calls to victims and their family members”.  ShinyHunters says that this is not accurate, and that they will release the FBI employee data, including information of employees and their family members, if the agency does not retract the statements, telling The Register “I have been doing my very best to combat these allegations, and this is the best way to do it”.

This Week In Security: Flock Cameras Are Old, Microsoft Patches Patches, And Researchers Attack SSH

September 18, 2026 by 12 Comments

Leak site Distributed Denial of Secrets has released a dump of the filesystems of a Flock camera, and Micah Lee has published a dive into the contents.  Apparently the Flock security model did not include “angry citizens with a hacksaw in the middle of the night” in the physical security category.

The first thing Micah notes is that the Flock hardware runs Android 8.1 (for those not keeping track, the current Android release is Android 17 released in June 2026).  The version of Android running on the Flock camera was last patched in June of 2018, and the Linux kernel (3.18.71) is over nine years out of date, and the 3.18 series went end-of-life in 2019.

You might assume “wouldn’t an operating system this old have known vulnerabilities?”, and you’d be completely right.  Micah calls out two in particular, one in the Qualcomm GPU which allows any program to manipulate kernel memory and gain root (similar, yet simpler, than the spate of kernel vulnerabilities this year that allowed manipulating memory via the disk IO cache), and the “WrongZone” vulnerability which allows a process to escalate to root via socket handling errors.  You might also guess both of these have been patched, and again, you’d be right, in 2021 and 2018 respectively.

Digging deeper, Micah discovers that API keys with access into the Flock infrastructure appear to be hard-coded into the binaries.  Each camera appears to request credentials from an authentication server, using the MAC address of the camera.  After obtaining the credentials from an Okta Auth0 sign-in service, the Flock stores them, in plain text.

Also stored on the camera unencrypted are logs and position data:  The camera dumped to Distributed Denial of Secrets came from a suburb of Milwaukee. Continue reading “This Week In Security: Flock Cameras Are Old, Microsoft Patches Patches, And Researchers Attack SSH” →

This Week In Security: It’s Patch Tuesday Again, TVs Spying, Supply Chain Worms Return, Prolonged Hack Impacts, Stolen IDs

September 11, 2026 by 16 Comments

Several times this summer, Microsoft’s Patch Tuesday, the monthly roundup of major security patches for Microsoft products, has included record-breaking numbers of security fixes. The August 2026 patch set actually seemed to catch up. Was this a sign of the bug apocalypse lessening? Ha, nope!

Brian Krebs at Krebs On Security once again brings his excellent roundup of Patch Tuesday events, with this months patch set absolutely crushing previous numbers with nearly 1,000 security fixes.

Two of the fixes are for zero-day vulnerabilities under active exploitation in the wild, both allowing privilege escalation on Windows. Privilege escalation bugs turn general vulnerabilities in applications and games into full administrator access to gain persistence and deploy ransomware, and generally make any vulnerability significantly worse.

Krebs also calls out a CVSS 9.8 (so close to a perfect 10!) vulnerability that allows remote code execution in the Windows shell with no user interaction and no authentication, a remotely exploitable DNS bug present since Windows Server 2012 and Windows 10 which will likely see exploitation in the wild soon, and over a hundred other bugs are ranked “Critical”.

How the sheer volume of vulnerabilities in this patch will fit with recent Microsoft recommendations that companies should apply the patches immediately remains to be seen. (Likely: not very well, depending on what new behavior and issues the fixes cause!)

Is Your LG TV Spying on You?

Gamers Nexus continues their trend of high-quality investigation, and they have posted another tremendous multi-hour investigatory video. This time Gamers Nexus focuses on the ecosystem of LG televisions and monitors.

It shouldn’t likely surprise many here that “smart” devices are usually more to the benefit of advertisers than consumers. Similarly, it shouldn’t be a surprise that a “smart” device harvests user data to sell to advertises. What may be surprising is the degree to which LG devices appear to collect data, how much data is sent even when collection is turned off, and how overt executives at the company are, with multiple executives making statements in pitches to advertisers that LG “owns the glass”, “owns the living room”, and is designed to correlate devices, inhabitants of the environment, and viewing habits so that ads can be served to the TV and mobile devices in the same room simultaneously.

With tracking enabled, the smart TV captures telemetry of what applications are used, as well as continually capturing the video displayed and reporting fingerprints to LG servers and ad partners. The screen content is tracked not only for TV, but for the HDMI inputs, including if the TV is used as a PC monitor. If voice control is enabled, the TV also records audio and analyzes it. The TV also continually scans the local network and nearby Wi-Fi networks, reporting all the devices it finds on the local network, including host name, MAC address, and sometimes software running depending on the MDNS advertisements. Near-by Wi-Fi networks are sufficient for very precise geolocation, so LG effectively knows the location of every customer, as well.

This Week In Security: Baked-in Malware, Freezers Not Freezing, Zoom Snoops Clipboards, And AI Makes Things Worse, Faster

September 4, 2026 by 18 Comments

The AI platform ServiceNow which offers both hosted and on-premises versions just patched a trifecta of CVSS-10 vulnerabilities.

CVSS rankings are determined by the severity of a flaw, the ease of exploiting the bug, if authentication is required for exploitation, if the vulnerability exposes confidential data, and other criteria. A CVSS of 10 is as bad as it gets, and having three of them at once is certainly attention-getting. Of the three vulnerabilities fixed, one allowed unauthenticated modification of data in the hosted instance, a second allowed arbitrary code execution via the GraphQL interface, and the third allowed arbitrary SQL commands that could modify the database.

ServiceNow claims Adobe, Lenovo, Fedex, and Fujitsu among their high-profile customers. With luck, the vulnerabilities were patched before significant public exploitation could happen.

Router Malware

Previously in 2026 the US Government warned against embedded malware found in consumer routers, which may be linked to the FCC enacting bans against certification and import of foreign-made consumer devices. This week, the NVD (National Vulnerability Database) reported specific embedded malware in the Zbtlink and MoreQuick brands of devices.

Multiple versions of the firmware, for multiple lines of products, contain a backdoor service that uses unencrypted UDP to connect to a command and control (C2) service. The service, or anyone able to intercept the network traffic, since it’s unencrypted, can execute commands as root, allowing them to change configurations, open tunnels, or steal ISP credentials.

The malware is baked into the firmware, so removing it is impossible for most users: a factory reset wouldn’t do. In theory if third-party firmware like OpenWRT supports these devices, the hardware could be made safer with a custom install.

Given how commonly the same device is marketed under dozens of names, likely the same devices and firmware have yet to be identified under other brands. Continue reading “This Week In Security: Baked-in Malware, Freezers Not Freezing, Zoom Snoops Clipboards, And AI Makes Things Worse, Faster” →
