Proofpoint threat researchers identified a new malware-as-a-service named #TrustConnect. Notably, it masquerades as a legitimate remote monitoring and management tool, marking an evolution in how attackers weaponize trust around enterprise tooling. brnw.ch/21x05Vh

Thanks to the proofpoint team for highlighting "TrustConnect Software PTY LTD". The actor got the cert hoping to look like a legitimate RMM—but in collaboration with Proofpoint—we didn't let them maintain the illusion. See Proofpoint's blog for all the details.
Would you run AdobeReader.exe from a days-old company called "TrustConnect Software PTY LTD" just because they managed to purchase an Extended Validation certificate? New blog out together with @proofpoint @threatinsight proofpoint.com/us/blog/threa…

As the security landscape evolves and expands, Proofpoint observed many threat actors disappear from email threat data in 2025. But TA584 maintained operational consistency, w/ recent shifts demonstrating its attempt to infect a broader range of targets. brnw.ch/21wZsWU

BTW looked at this thing back in September that likely is related: virustotal.com/gui/domain/fe… which then goes back to at least January last year.

Nice writeup, but Smokest might not be a good name, its likely just a campaign indicator. Example virustotal.com/gui/file/0bd1… Fake OBS > Donut > Amadey > Various MSI > PowerShell that I have seen lead to either this or CastleRAT via Python loader, Smokest120[.]zip.

Proofpoint is proud to have assisted law enforcement in the #OperationEndgame investigation that led to the Nov. 13, 2025 disruption of #Rhadamanthys and #VenomRAT—#malware used by multiple cybercriminals. Rhadamanthys: brnw.ch/21wXsCc VenomRAT: brnw.ch/21wXsCd

Since 14 Oct., we’ve tracked a high volume XWorm campaign targeting Germany. The activity is attributed to TA584, a sophisticated #cybercrime group tracked since 2020. Messages are sent from hundreds of compromised sender accounts impersonating ELSTER and contain malicious URLs.

Threat actors continue to abuse GitHub to deliver malware, this time: #LummaStealer. We identified GitHub notification emails that kick off the attack chain. Messages are sent when the threat actor, using an actor-controlled account, comments on existing GitHub issues. 🧵

The notifications contain shortened URLs that will lead to an actor-controlled website. The website will perform filtering functions, and if those checks are passed, the visitor will be redirected to a website that presents a fake GitHub-branded CAPTCHA instructing users to verify they are human.

We identified GitHub notification emails that kick off the attack chain. The emails are likely generated by the threat actor creating an issue in an actor-controlled repository with a fake security warning, and then tagging legitimate accounts who receive notifications that they have been tagged, with the text from the issue.

Proofpoint @threatinsight identified a unique attack chain leveraging GitHub notifications to deliver #Rhadamanthys. We first spotted this post by @anyrun_app about ClickFix delivering Rhadamanthys and began investigating. 🔍
🚨 How #Rhadamanthys Stealer Slips Past Defenses using ClickFix ⚠️ Rhadamanthys is now delivered via ClickFix, combining technical methods and social engineering to bypass automated security solutions, making detection and response especially challenging. 👾 While earlier ClickFix campaigns mainly deployed #NetSupport RAT or #AsyncRAT, this C++ infostealer ranks in the upper tier for advanced evasion techniques and extensive data theft capabilities. #ANYRUN Sandbox lets SOC teams observe and execute complex chains, revealing evasive behavior and providing intelligence that can be directly applied to detection rules, playbooks, and proactive hunting. 🔗 Execution Chain: ClickFix ➡️ msiexec ➡️ exe-file ➡️ infected system file ➡️ PNG-stego payload In a recent campaign, the phishing domain initiates a ClickFix flow (#MITRE T1566), prompting the user to execute a malicious MSI payload hosted on a remote server. 🥷 The installer is silently executed in memory (#MITRE T1218.007), deploying a stealer component into a disguised software directory under the user profile. The dropped binary performs anti-VM checks (T1497.001) to avoid analysis. In later stages, a compromised system file is used to initiate a TLS connection directly to an IP address, bypassing DNS monitoring. 📌 For encryption, attackers use self-signed TLS certificates with mismatched fields (e.g., Issuer or Subject), creating distinctive indicators for threat hunting and expanding an organization’s visibility into its threat landscape. 🖼️ The C2 delivers an obfuscated PNG containing additional payloads via steganography (T1027.003), extending dwell time and complicating detection. 🎯 See execution on a live system and download actionable report: app.any.run/tasks/a101654d-7… 🔍 Use these #ANYRUN TI Lookup search queries to track similar campaigns and enrich #IOCs with live attack data from threat investigations across 15K SOCs: intelligence.any.run/analysi… intelligence.any.run/analysi… intelligence.any.run/analysi… intelligence.any.run/analysi… 👾 IOCs: 84.200[.]80.8 179.43[.]141.35 194.87[.]29.253 flaxergaurds[.]com temopix[.]com zerontwoposh[.]live loanauto[.]cloud wetotal[.]net Find more indicators in the comments 💬 Protect critical assets with faster, deeper visibility into complex threats using #ANYRUN 🚀 #ExploreWithANYRUN

New e-crime insights: TA4557, known for distributing More_eggs malware, notably expanded to an int'l audience in recent campaigns. Per our data, the recruiter-focused TA was seen targeting orgs in France, England & Ireland, in addition to typical North America-targeted threats.

Proofpoint also recently observed this activity delivering #GootLoader. Google Ads for a fake document creation app (lawliner[.]com) led to a malicious document creation website, on which users are directed to enter their email address.

Proofpoint has tracked this technique since August 2024, and call it “brooxml”. Our researchers do not consider this a zero-day or vulnerability in general. We’ve released Emerging Threats and YARA signatures at the end of this thread.
🚨ALERT: Potential ZERO-DAY, Attackers Use Corrupted Files to Evade Detection 🧵 (1/3) ⚠️ The ongoing attack evades #antivirus software, prevents uploads to sandboxes, and bypasses Outlook's spam filters, allowing the malicious emails to reach your inbox The #ANYRUN team discovered that as part of this #zeroday attack, threat actors attempt to conceal the file type by deliberately corrupting it, making it difficult for certain security tools to detect 📌 Our sandbox solves this problem thanks to interactivity. It launches these broken files in their corresponding programs, which allows it to identify #malicious behavior See example: app.any.run/tasks/6839e806-5… 🚫 Although these files operate successfully within the OS, they remain undetected by most security solutions due to the failure to apply proper procedures for their file types They were uploaded to VirusTotal, but all antivirus solutions returned "clean" or “Item Not Found” as they couldn't analyze the file properly

Proofpoint researchers have identified an increase in the #socialengineering technique called #ClickFix. The technique is being used by financially motivated threat actors and reportedly by suspected espionage-focused groups. Read the security brief: ow.ly/WYXX50U9eZq.

Threat actors are impersonating the British postal carrier Royal Mail in an attempt to deliver Prince #ransomware. In the small campaign, most messages appear to come from contact forms posted on the target organizations’ websites. Details in our blog: ow.ly/XLY150TAZFF.
