Security and finance leaders think they're aligned. Our new research with 300 of them says otherwise. 54% of finance leaders need strategic alignment metrics. Security's giving them maturity metrics instead. The language barrier is real—and fixable. expel.com/blog/new-res...

We just dropped a new AI upgrade 🫳 Now you get plain-English explanations for every detection rule. See exactly which rules are firing, how your coverage evolves, and what's actually protecting you. Transparency isn't a feature, it's how MDR should work. expel.com/blog/new-exp...

We're seeing XMRig cryptominers popping up everywhere recently. Threat actors love them because they’re a simple way to make money, and they can go unnoticed. Here's how to spot them and shut them down before threat actors start monetizing: expel.com/blog/on-the-...

Our security leaders made their (brutally honest) 2026 predictions. The one thing they agree on? AI isn’t going anywhere, and it’s bringing new capabilities and threats into the new year. Read all of their unfiltered takes: expel.com/blog/cyberse...

Your analysts are drowning. You can't hire fast enough. And even if you could, the math doesn't work. The economics of running a 24×7 SOC have changed. Use our free calculator that shows you what your team needs whether that's building, buying, or augmenting: expel.com/blog/buildin...

In the SOC, you get used to the noise. But a couple weeks ago, a single string cut through the noise: SHA1HULUD. It felt like seeing a ghost. We traced the activity to a public GitHub repository where the customer's private cloud keys and secrets were exposed for anyone to grab.

Expel MDR now supports Panther. We integrate with your cloud-native SIEM, bringing our detections, 24x7 monitoring, and incident response to work alongside what you've already built. Use the tools that work for you. We'll make them work harder. expel.com/blog/more-si...

⚠️ Attackers are buying Google Ads that appear when looking up how to troubleshoot your Mac. The ad takes you to a shared ChatGPT chat that tells you to copy-paste some code. You've just executed malware. Kroll has a solid write-up on the mechanics: www.kroll.com/en/publicati...

Part two of our QTR, Q3 2025 just dropped: malware disguised as apps that actually work. BaoLoader hides backdoors in PDF editors and browsers. TamperedChef is a recipe app with hidden command codes. These apps function as promised, which is why users don't suspect anything.

Imagine searching for Microsoft Teams, visiting the link at the top of the results, & getting hit with malware. That's the malvertising campaign that the Rhysida ransomware gang has been running. Expel Intel is tracking this campaign. Here's what we've uncovered: www.theregister.com/2025/10/31/r...

Q3 2025 Threat Report is out. We analyzed thousands of real incidents across customer environments. Here’s what stood out: 73.9% of all incidents were identity-based attacks. Up from 67.6% last quarter. Let’s dive into the Q3 numbers 🧵

The Rhysida ransomware gang (formerly Vice Society) is running the same playbook as last year—buying Bing ads to deliver fake Microsoft Teams, PuTTy, and Zoom downloads. Click the wrong sponsored result? You’ve just installed OysterLoader, their initial access malware.

⚠️Attackers are actively exploiting CVE-2025-59287, a recently identified vulnerability in WSUS. Successful exploitation allows an attacker to run code using SYSTEM privileges. Expel caught & contained incidents related to this in two customer environments this AM. Details: expel.com/blog/wsus-re...

Attackers found a clever way to abuse legitimate, digitally signed software to load malware and it's working. Expel Intel’s Marcus Hutchins (@malwaretech.com) breaks down a campaign that weaponizes Greenshot, a legit screenshot tool, to evade detection at multiple layers. 🧵

Halloween might be the spookiest day in October but this month's Patch Tuesday is a close second. 175 new CVEs from Microsoft, 8 marked critical, 6 zero-days, 2 already exploited in the wild. But not to fear, our threat intel team breaks down the 3 you should patch first. expel.com/blog/patch-t...

⚠️ Our threat intel team just caught attackers using a clever new trick to bypass security tools: cache smuggling. Instead of downloading malware, they hide it in fake images that browsers automatically cache. Then PowerShell extracts and runs it—no web requests needed.

The security industry is drowning in threat feeds that don't actually help you stop attacks. We've been working to fix that for years. Today, we’re taking the wraps off our expanded threat intel program: Expel Intel. (1/7)

50k events/day. 0.1% true positive rate. 50 real threats buried. That's what happens when you optimize for integration count, not detection quality. Vendors brag about "300+ integrations" while analysts burn out investigating false positives. Start counting what matters: expel.com/blog/stop-co...

Your email security quarantined the malicious email. 🚨📧 Victory, right? Not quite so. Several employees already clicked the link and installed attacker-controlled tools.

Chinese threat actors were building a network of SOHO routers and marking their territory with TLS certs that spoofed the LAPD. Our threat hunters found them anyway. 🕵️

⚠️ We’ve recently witnessed new activity in the realm of potentially unwanted programs (PUPs), which are dropping malware, executing commands, and turning your machine into someone else's proxy network. Read our ongoing investigation here: expel.com/blog/you-don...

🚨 A NEW trojan on the block spotted by our threat intel team 👀 We saw files with the code-signing signature “GLINT SOFTWARE SDN. BHD.” due to a JavaScript dropping “ManualFinder” One of their signed files, a PDF editor, turns your device into a residential proxy—ew. 🧵👇

⚠️ We’ve noticed a campaign leveraging SEO poisoning to drop a small loader. If you’ve seen the lure in the watering hole, we’d love to know. A copy of the malware can be found on VirusTotal as MD5 hash 6af56c606b4ece68b4d38752e7501457. Here’s what we’re seeing 🧵

⚠️ We’ve been keeping a close eye on the US-Israel-Iran geopolitical situation. Many resources are providing a ton of information and data but not a lot of analysis. Our take: things are not likely to intensify in the cyber realm. Here's what to do and what Expel is doing:

📂💥 When a malicious file hits your environment, every second counts. Expel's “delete malicious file” response action enables our SOC to permanently remove a confirmed malicious file directly from an affected host, using the EDRs and security tools you already have. expel.com/blog/explore...

⚠️🕷️ Scattered Spider is acting with a heightened amount of activity. We're seeing them pivot from credential harvesting to directly targeting IT help desks, using social engineering to reset passwords and bypass MFA. Get the full 411 on Scattered Spider's heightened activity:

It’s Patch Tuesday! 🩹 This month, Microsoft released 66 CVEs including CVE-2025-33053 and CVE-2025-33070. Of the vulnerabilities, here are the three that caught our eye as the highest priority due to the vulnerability exploitation risk factors 👀🚨 expel.com/blog/patch-t...

Identity has become the new frontline in cybersecurity. 🪪 🎥 In this interview with ISMG at #RSAC 2025, our CEO Dave Merkel shares why threat actors are prioritizing identity-based attacks and what security leaders should ask when evaluating AI-enabled tools. www.databreachtoday.com/identity-new...

If you're one of the many orgs that consolidated their security tools around @microsoft.com to keep costs down and now need an MDR provider to protect these new investments, you're in the right place. 🍀 Learn how Expel MDR works seamlessly with your Microsoft environment: expel.com/blog/simplif...

When it comes to any kind of addition to your tech stack, there’s always a lingering question: to build or to buy? 🤔 Do you challenge yourself to find and build it in-house or look for an MDR service provider to partner with?

In previous Quarterly Threat Reports, we focused on trends in malware & what our SOC is seeing. For our latest QTR, we focused on attack surface types to create a more tactical approach. However, we still have great data on malware trends we want to share—so here’s the 411: expel.com/blog/mdr-ins...
