A package gets installed. A login prompt opens. A box sits exposed to the internet. Nothing looks unusual yet.
That’s roughly the mood this week. Trusted tools turn hostile, old weak spots get fresh attention, AI makes exploit work cheaper, and researchers keep finding attacks that sound harder than they actually are.
Plenty to clean up. Here’s the short version.

Cybersecurity researchers have flagged two new malware families called WordlistLoader and SynkLoader that's used to deliver next-stage payloads and likely sell access to ransomware groups.
According to findings from Gen Digital, WordlistLoader is being used to deliver Amatera Stealer (aka ACR Stealer or AcridRain Stealer) via ClearFake campaigns, which employ the ClickFix (aka FakeCaptcha)
Developer Matt Callaghan claims he caught Alibaba trying to track web users by playing sounds through browsers vulnerable to audio fingerprinting. The software engineer drew attention to the issue late last week after investigating why his Bluetooth headphones stopped playing music whenever he visited Alibaba's website. “Recently I ran into a strange problem with my Bluetooth headphones,” Callaghan wrote. “They support multipoint Bluetooth audio, so they can be connected to my PC and phone at the same time. Normally, the PC takes priority playing audio, with my phone being able to play audio when nothing is playing on the PC. “Usually I listen to music on my phone but with notifications or YouTube playing through the PC, this works reliably until I open an AliExpress page in Firefox or Chrome. “Shortly after loading the AliExpress homepage, audio from my phone would stop playing. Closing the AliExpress tab fixes it immediately. Muting the tab/Firefox/Windows does not help, and there is no visible video, music, or other media playing on the page.” Callaghan tried to find any hidden conventional media elements but found nothing. Further digging revealed two audio scripts that he said were “extremely obfuscated” within Alibaba’s browser security and anti-abuse tooling. He said the scripts built a WebAudio graph that introduced a sawtooth oscillator to generate a waveform, an analyzer to measure the result after the waveform passes through a browser’s audio implementation, and a script to read the associated frequency data. The scripts set the audio’s gain to zero, meaning the end user won’t hear anything, but the WebAudio graph will still be processed by the browser. “This is very different from an autoplaying video,” said Callaghan. “There is no media element for the browser's normal tab mute control to stop. As far as the page is concerned, it is performing live audio processing. “In my case, that appears to have been enough for Firefox or Windows to keep the Bluetooth audio path active, preventing my multipoint headphones from switching cleanly back to the phone.” Callaghan found further evidence in the code of Alibaba looking for data related to screen dimensions, device memory, browser plugins, WebGL rendering, mouse events, and more. As well as signs that Alibaba is encrypting data and sending it to its telemetry services, the developer said all of it amounts to “a fairly comprehensive browser and device fingerprint.” The Register has asked Alibaba to comment. Despite Callaghan saying he could reliably reproduce this issue on both Firefox and Chrome, Firefox issued a Xtatement saying its anti-fingerprinting technology thwarts Alibaba’s tracking tricks. It pointed to a blog post from Tom Ritter, a security engineer on the Firefox team, who explained that as of version 118 (September 2023), the protections it introduced eliminated the efficacy of WebAudio-based fingerprinting. These protections are not designed to stifle fingerprinting efforts at the source. Instead, they work to group all users together, making it look like all fingerprinted users are the same, effectively nullifying the tracking attempts. For 99.24 percent of users, they fall into one of three “buckets” – user categories delineated by types of hardware. The vast majority fall into buckets one and two: Bucket one: x86/x64 CPUs lacking FMA (Fused Multiply-Add) instructions Bucket 2: x64 CPUs with FMA instructions And for the remaining 0.76 percent, the fingerprinting script failed entirely, according to Firefox’s data. However, Ritter said there are 48 users worldwide who do not fall into the three buckets, or the 0.76 percent whose machines did not allow the scripts to run. These 48 users fell into 23 other minuscule buckets, which means they are not grouped into the masses like the rest, and so fingerprinting is more effective on this vast minority of users. “This is very unfortunate, as it makes these users completely unique, but it is also not terribly unusual - computers are weird and these results could have been caused by bad RAM, a CPU bug, or possibly some crazy architecture (LoongArch??),” said Ritter. “But at the end of the day, WebAudio fingerprinting is nearly useless. I don't expect browser fingerprinting to disappear from websites entirely (unless some regulatory action occurs, fingers crossed) - it's still going to be effective against a majority of users on the web, but at least for privacy-focused browsers, it should be wildly less effective.” Brave, maker of the eponymous privacy-centric browser, also Xeeted a response to Calalghan’s findings, saying it has protected users from fingerprinting for six years. “Brave injects random data into the browser's output so you show a different fingerprint to different sites. This fingerprint also resets across sessions. “For added protection, we also block the specific scripts used by AliExpress for the tracking method mentioned above. Again, this is done by default for all Brave users. You don't have to change any settings to be shielded from this audio fingerprinting.” Ritter said Chrome and Safari “probably have defenses against this [brand of fingerprinting].” Safari deploys Advanced Tracking and Fingerprinting Protection to prevent WebAudio-based tracking and other methods of fingerprinting. It works differently to Firefox, though, injecting audio errors into an audio buffer, instead of trying to lump all users into an identical bucket. Chrome, on the other hand, does not aggressively protect users from fingerprinting, as privacy consultant Alexander Hanff said earlier in the year. "There are at least thirty distinct fingerprinting techniques that work in Chrome right now, today, as you read this," he wrote. "Not theoretical attacks from academic papers that might work under laboratory conditions – real, production techniques deployed on millions of websites to identify and track you without your knowledge or consent." ®
If your developers are using AI coding tools, you are probably already seeing the upside: faster development, more code, and less time spent on routine work.
The harder part is what comes after. AI can also introduce open-source packages at a pace your security team was never built to handle. More dependencies mean more vulnerabilities to review, more remediation work, and a backlog that can
Red Hat and the Keycloak project have released patches to address a critical security flaw in the open-source identity and access management server that could allow an unauthenticated remote attacker to take over any user account by forcing a password reset.

Are you sick and tired of maintaining a password manager? Struggling with choosing the right one for you? Well, readers who live Down Under can get themselves down to their local AusPost branch where they can pick up an old-school alternative for just AU$4.90 (US$3.51). Password books are something of a historical relic, phased out largely because of the scrutiny associated with using one and the now-gray-haired elders who once scoffed at the mere notion of such an opsec crime. They might not be able to suggest a strong password for each of your many online accounts, and they won’t do you much good if your house is burgled, but you could argue that there is still value to be found in a pen-and-paper password vault. That’s exactly the conclusion drawn by the thousands of social media users who flocked to a post this week from one Australian who found stacks of password books for sale in their local post office. Small books are priced at AU$4.90 (US$3.51), while larger options will set you back a dollar extra. Granted, there are myriad issues associated with relying on a physical document for digital account security. For one, it’s a single point of failure. Lose the book or have it stolen, and it’s a painful road to restoring access to all your accounts. One could argue that if it’s kept inside the home and it’s stolen, then you’ve got bigger problems on your hands, but perhaps that’s not as true nowadays, when so many of our valuables are either stored or primarily accessed online. That said, it might bring a quick end to a hostage scenario – the type that is becoming all the more common as crypto wealth becomes increasingly common. Password books are also not as easily manageable as a modern password manager. The technological equivalent can auto-fill credentials, auto-update them if they’re found in public breaches, and suggest unique, strong strings to minimize the risk of compromise. You can’t store a passkey in a password book, either – a major issue now that the world is transitioning toward the new authentication standard. But using a password book no longer carries the same stigma as it once did among infosec types. The general consensus, gleaned from the hundreds of social media comments on the post, now seems to be that there's little wrong with storing passwords on paper at home. It’s certainly more secure than reusing the same weak password across multiple accounts, provided the book contains strong strings unique to each website. With the prevalence of infostealers nowadays, it's far more likely that crims will use a weak, reused, seldom-changed password to break into an online account than burgle a house to gain access to someone’s online banking. Plus, as many pointed out, it’s a much better route than writing passwords in a cloud document, which can be accessed by any device that has access to it – think Apple Notes, Google Docs, etc. At work, though, it’s probably best to stick to the password manager, the IT guys say. Mistakes by staff working at even the lowest rungs of the corporate ladder could lead to multimillion-dollar cyberattacks should that password book fall into the wrong hands. Pentesting consultants often send hired white hats to breach a company’s office and extract whatever value they can, sometimes through piss corridors. Such access can lead to malicious USB sticks dropping malware, bugs planted near the water fountain, and even someone stealing the password book from your desk drawer. Don’t believe it’s real? Security consultant Alethe Denis told us two years ago that’s exactly how her pentest team was able to surreptitiously extract corporate data over a company’s own Wi-Fi for over a week. They went dumpster diving, got the Wi-Fi creds, walked straight into a conference room, and deployed a data-stealing implant. In and out, all using physically stolen secrets. Helpful in the worst of times So, yes, password books contain plenty of potential pitfalls, Poignantly, however, they often prove invaluable in the event of a loved one’s passing. Having access to a password book, or at least some sort of plan to share passwords in the event of a death, is vital to ensuring family and friends have space to grieve without going through the arduous process of recovering an account through a platform provider, or via the courts. A slew of Redditors agreed, saying it made the whole process so much easier. One shared the tale of how their mother’s own special way of storing passwords resulted in a treasured family investigation. After password books spent years as outcasts of the cybersecurity world, they’re now having a second moment in the sun. And while the leading minds in cybersecurity are busy working on ways to stop phisherfolk from hacking into your accounts, or rogue AI agents from doing the same, there’s still something to celebrate in the safeguards of yesteryear, both in life and death. ®
