We all just need to agree that ad blockers are good
YouTube’s new rules may not be around for long anyway, because they might run afoul of European Union regulations

I don’t think this is a particularly bold take — but I’m not afraid to say that ad blockers are good!
Ever since I started using one sometime in 2016, my experience of using the internet has improved exponentially. I can finally easily find a recipe for dinner on a random influencer’s blog, get a faster answer to “how to replace my car’s headlights” and likely avoid hundreds of pieces of malvertising.
But their use has increasingly come into question with YouTube’s new policies on preventing users from using ad blockers on its site, with new warnings saying the user has a certain number of videos they can watch before they must allowlist youtube.com in their ad blocker, thus allowing the site to display ads before YouTube videos.
The second this popped up for me two weeks ago, I immediately started researching workarounds and quickly found a secure solution that works for my browsing habits. The easy explanation for why Google (YouTube’s parent company) wants to get rid of ad blockers is, simply, money. They run the Google Ads service that provides the stereotypical ads everyone has been used to seeing on websites since the early aughts. Unfortunately, bad actors will often use enticing headlines, fake images or sales pitches to trick people into clicking on links that lead to malicious sites, attacker-run scams or downloads that are malware.
Ad blockers are a major tool users can deploy to block this type of threat, so the explanation for why everyone should be using one is also clear.
Google isn’t the only major company looking to bypass ad blockers, either. Spotify’s terms of service explicitly outlaws “circumventing or blocking advertisements or creating or distributing tools designed to block advertisements” on its platforms, and many news websites like CNBC have warnings about turning off your ad blocker before you can proceed to read an article.
I am all for publishers charging for their content or putting it behind a paywall, or even “premium” subscriptions to disable ads from podcasts or videos. But we all need to universally agree that ad blockers (at least legitimate ones) are good for the internet at large and keep users safer. The FBI and CIA agree with me on this and have both advised that users enable ad blockers in web browsers before.
The argument that ads benefit the creators, and therefore we’re robbing them of money, is largely off-base from these corporations.
Creators who are part of the YouTube Partner program, which means they have filled out an application and meet a minimum standard for views and subscribers, make between $1.61 and $29.30 for every 1,000 views on their videos through YouTube’s ads. So Mr. Beast might make a decent payday out of that every month, but I’m sure Mr. Beast would also be doing just fine without the extra few thousand dollars in his pocket currently.
The people who are just trying to be helpful by showing me how to fix my washing machine or install a car seat properly are likely not missing my singular ad view when I use an ad blocker.
Thankfully, YouTube’s new rules may not be around for long anyway, because they might run afoul of European Union regulations, and privacy advocates have already filed a formal challenge to the EU’s independent data regulator.
**The one big thing **
Microsoft disclosed three zero-day vulnerabilities as part of its monthly security update this week, and all three have already been added to CISA’s Known Exploited Vulnerabilities catalog. However, Patch Tuesday only included three critical vulnerabilities, an unusually small number based on previous months’ Patch Tuesdays. CVE-2023-36033 is an elevation of privilege vulnerability in the Windows DWM Core Library that could allow an attacker to gain SYSTEM-level privileges. According to Microsoft, this vulnerability has already been exploited in the wild and there is proof-of-concept code available. Another zero-day elevation of privilege vulnerability, CVE-2023-36036, exists in the Windows Cloud Files mini-filter driver that could also allow an attacker to gain SYSTEM privileges.
**Why do I care? **
Unfortunately, zero-days have become commonplace for Patch Tuesdays this year, and it seems like a few more pop up each month. In these cases, attackers were able to discover the exploits before Microsoft had a chance to patch them, and CISA already acknowledged that attackers are exploiting these vulnerabilities in the wild.
**So now what? **
All Microsoft users should ensure their updates are installed correctly if you have auto-update on, or make sure to manually download the patches as soon as possible otherwise. The Talos blog also has a rundown of Snort rules that can detect the exploitation of many of the vulnerabilities Microsoft disclosed this week.
**Top security headlines of the week **
U.S. intelligence agencies are warning that the Royal ransomware group could soon be headed for a rebrand and may already be operating under the name “BlackSuit.” Government sanctions have previously limited Royal’s ability to make money off their ransomware attacks, but new research from private firms and government agencies indicate that Royal may be connected to BlackSuit, another threat actor that uses similar open-source tools. Royal is a prolific ransomware group that the FBI says is responsible for infecting more than 350 companies, generating revenue in excess of $275 million. Security researchers are also speculating that Royal may have formed from the splintering of the former Conti ransomware gang, which was also the victim of sanctions and government takedown efforts. The U.S. and U.K. announced sanctions against 11 individuals believed to be a part of Conti in September. (TechCrunch, The Register)
Fighting election misinformation has only gotten more difficult since the 2020 presidential election. New reporting and testimony indicate that many key programs and partnerships dedicated to fighting fake news and disinformation online have eroded over the past few years after political attacks from right-wing leaders and organizations. FBI Director Chris Wray told a Senate committee last week that an alliance of federal agencies, tech companies, election officials and security researchers dedicated to fighting foreign propaganda has fallen apart recently, with little to no communication between the various parties involved. Other officials in charge of fighting election disinformation say its been months since they heard from the FBI after once connecting with the agency regularly about fighting fake news on social media platforms. Additionally, many poll workers and election officials are afraid to discuss the topic after years of online pushback from right-wing voters who view the word “misinformation” as a synonym for censorship.

Chip makers Intel and AMD disclosed new vulnerabilities this week that could lead to privilege escalation. Some Intel CPUs are vulnerable to the newly discovered “Reptar” vulnerability (CVE-2023-23583) that was disclosed on Tuesday. Adversaries can exploit this high-severity flaw if they already have access to the targeted system, eventually causing a crash on the machine leading to privilege escalation or the disclosure of sensitive system information. Another attack on AMD CPUs called “CacheWarp” could allow an attacker to infiltrate encrypted virtual machines and perform privilege escalation. This vulnerability, identified as CVE-2023-20592, affects AMD’s Secure Encrypted Virtualization (SEV) technology. Users do not need to take any additional actions to address these vulnerabilities other than ensuring drivers and operating systems are up-to-date and patched. (SecurityWeek, The Hacker News)
**Can’t get enough Talos? **
Rather than putting a bunch of links here this week, I instead encourage you to watch this whole segment from Fox 11 in Los Angeles, featuring Nick Biasini from Talos Outreach. The story covers online scams, but features Nick discussing Talos’ recent research into various scams in the online video game “Roblox.”
