Passkey-themed phishing attacks lead to Microsoft 365 data theft

Microsoft links ShinyHunters- and Helix-affiliated actors to passkey-themed vishing and device-code phishing that compromises Microsoft 365 accounts and steals cloud data.

Microsoft attributes passkey- and SSO-themed social engineering activity, observed since May 2026, to Storm-3121 (linked to ShinyHunters and Falcon) and Storm-3032 (tied to BlackFile members now operating as Helix). Attackers impersonate corporate IT help desks by phone or SMS, urging fake passkey, MFA, or SSO updates and directing victims to adversary-in-the-middle phishing pages or device-code authentication flows that yield credentials, session tokens, and OAuth tokens. Post-compromise behavior includes Microsoft Graph enumeration of users, SharePoint, and OAuth grants, plus persistence via attacker-controlled MFA methods. Google Threat Intelligence tracks related activity as UNC6671, linked to the BlackFile, Helix, Falcon, Pink, and Redact extortion gangs.

Spark RAT Targets Cambodia, Abuses Vulnerable OPSWAT Driver to Disable Security Tools

Acronis details a Spark RAT campaign against Cambodia abusing the vulnerable OPSWAT ardrv.sys driver (CVE-2026-36425) to disable Microsoft Defender and other security tools.

Acronis TRU analyzed a multi-stage Spark RAT campaign targeting Cambodian individuals and organizations with lures spanning government notices, public health materials, and real estate documents. Attack chains use phishing emails with Inno Setup archives, DLL side-loading via a signed Tencent executable, and BYOVD abuse of the vulnerable OPSWAT ardrv.sys driver (CVE-2026-36425) to terminate security software. Shellcode hidden in PNG files patches AMSI and ETW, establishes scheduled task and service persistence, and injects into vssvc.exe and ctfmon.exe to run the open-source Go-based Spark RAT. Tactics resemble the Silver Fox actor, but Acronis tracks the cluster as unattributed with low confidence.

Aggah Campaign: Bit.ly, BlogSpot, and Pastebin Used for C2 in Large Scale Campaign

Aggah campaign abuses Bit.ly, BlogSpot, and Pastebin as multi-hop C2 to deliver RevengeRAT across the Middle East, US, Europe, and Asia.

Unit 42 details the Aggah campaign, which began with spearphishing emails in March 2019 spoofing a large financial institution and targeting education, media/marketing, and government organizations in the Middle East, later expanding to the US, Europe, and Asia. Delivery documents use Template Injection to load a remote OLE file whose macro runs mshta against a Bit.ly link redirecting to a BlogSpot post, which then uses Pastebin pastes to download RevengeRAT configured with a duckdns[.]org C2 domain. The embedded script also deletes Microsoft Defender signatures and kills Defender and Office processes, and modifies registry keys to enable macros. High-level TTPs resemble the Gorgon Group, but Unit 42 could not confirm attribution.

Smishing Triad Hackers Use JWR Phishing Kit to Steal Cards, OTPs and Bank Credentials

Group-IB attributes large-scale smishing using the JWR real-time phishing kit to the Smishing Triad's Outsider cluster, harvesting card data, OTPs, and bank credentials.

Group-IB attributes a large-scale SMS phishing campaign to Outsider, an operator sub-cluster within the Smishing Triad phishing-as-a-service ecosystem, using a kit dubbed JWR. The Vue 2-based platform maintains real-time WebSocket communication with operators, enabling them to adapt pages live and harvest roughly 70 PII fields, card data, PINs, OTPs, identity document images, and digital wallet credentials via a dedicated PayPal sub-funnel. Unit 42 previously tied 194,345 malicious domains across 136,933 root domains to the broader operation since January 2024. Defenders can hunt for /api/open/ endpoints, /webSocket/QT/ paths, JWR-prefixed storage artifacts, and a hard-coded WebSocket token.

Phishing Campaign Sends Millions of Emails Using Invisible Unicode to Evade Filters

Microsoft warns of a high-volume phishing campaign using invisible Unicode characters to split keywords like 'funding' and evade filters, peaking at 2.37 million daily messages.

Microsoft's Security Research team documented a high-volume phishing operation inserting deprecated Unicode Tags characters (U+E0000-U+E007F) inside financial keywords such as 'funding' so literal-string and regex email filters stop matching them. The campaign ran on a weekly cadence with 1-2.37 million weekday messages between February and May 15, 2026, peaking on February 26, 2026. It used hundreds of disposable finance-themed sender domains and relayed mail through ActiveCampaign's click-tracking infrastructure (acemlnd[.]com, activehosted[.]com), lending legitimate platform reputation. Microsoft ties the activity to an AI-assisted SBA loan phishing campaign that Fortra's FIRE team disclosed in September 2025.

New Chaos Variant Targets Misconfigured Cloud Deployments, Adds SOCKS Proxy

Darktrace says the Chaos botnet now targets misconfigured cloud deployments like Hadoop and added a SOCKS proxy for traffic relaying.

Darktrace identified a new 64-bit ELF variant of the Chaos botnet targeting misconfigured cloud deployments, expanding beyond the malware's traditional focus on routers and edge devices. Captured in a deliberately misconfigured Hadoop honeypot instance, the intrusion began with an HTTP request creating an application that ran embedded shell commands to fetch the Chaos agent binary from pan.tenire[.]com, set chmod 777 permissions, execute it, and delete the artifact to reduce forensic traces. The restructured variant adds a SOCKS proxy feature letting compromised systems ferry attacker traffic, while removing SSH-based spread and router-exploit functions, suggesting monetization beyond crypto mining and DDoS-for-hire. Possible Chinese origin is suggested by language artifacts and infrastructure; the delivery domain was previously used in Silver Fox's Operation Silk Lure phishing campaign delivering ValleyRAT.
