The Axios npm package is a component of many popular applications. Its compromise in turn impacted a lot of systems and software that relied on it. The package was actively serving a remote access trojan to Windows, macOS, and Linux systems. 1/3

Iran's cyber capabilities — ransomware, data wipers, stated intent to target Western infrastructure — aren't theoretical. Expel's James Shank and Iran intel expert Steph Shample give security teams the straight picture: what's real, what it means, and what to do about it. expel.com/resource/ira...

We continue to see high volumes of targeted phishing via Microsoft Teams. The following are malicious senders just from this past week: Corporat[@]HelpDeskFoundation[.]onmicrosoft[.]com service[@]helpdeskfoundation[.]onmicrosoft[.]com helpdesk[@]omkarcis[.]online 1/5

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 🧵
