🚨Alert: New cryptocurrency stealer likely written in Zig 🔬Report: vmray.com/analyses/vidar… We found a multi-stage infection chain delivering what appears to be a new cryptocurrency clipper, likely written in Zig. The infection begins with Vidar, which drops a heavily obfuscated AutoIt script that injects and executes the Zig-based stealer. This stealer resolves its C2 address through a BSC smart contract, a technique known as EtherHiding. Its primary purpose appears to be replacing cryptocurrency addresses in the clipboard with an attacker-controlled wallet. 🔎 In a nutshell: -Vidar → SFX → AutoIt Loader → Zig Crypto Stealer -The AutoIt script is heavily obfuscated, the next-stage payload is RC4-decrypted then LZNT1-decompressed at runtime before injection -Script contains junk code and performs multiple anti-sandbox and anti-AV checks, timing-based evasion, and a DNS request to a non-existing domain -C2 address is resolved via a BSC smart contract (EtherHiding) -Constantly polls clipboard for multiple cryptocurrency address formats: BTC, ETH, etc. -When a match is found: exfiltrates the victim's original address to the C2 and replaces it with attacker wallet -Likely written in Zig as some strings are uniquely associated with that language -Querying the attackers smart contract transactions, one can identify many more C2 addresses -In recent days the sample seems to drop a different payload, no longer the Zig crypto stealer 🧬 IoCs: -Zig sample SHA256: a82d031d99b15f8eb5a1d8cc24e55fec6d393d549edde8da9507f3cf17503ce1 -C2: quartermaster-sec[.]cc -Smart contract address: 0x7CC3cFC1Ac007B8c6566fD2C7419b15a75473468 via API endpoint hxxps[:]//data-seed-prebsc-1-s1[.]binance[.]org:8545 -Vidar sample SHA256: 62338c7764f4e82105ea52fab868e1f04dc2f54bb44c5a47ddac685eacd6ed3c -C2: 65.21.165[.]15 -Steam profile: hxxps[:]//steamcommunity[.]com/profiles/76561198736378968 🧩 More C2's from other smart contracts by the same creator: -artisan-advertising[.]cc -brain-game[.]cc -celebration-internet[.]cc -cmicrosoft1[.]click -devops-offensive[.]cc -ed-security-buff[.]cc -en.hugo-lapp[.]co -evil-toy[.]cc -fast-node[.]com -firewall-sentinel[.]cc -flame-guard[.]cc -kr.hugo-lapp[.]co -lavande-rocket[.]cc -quartermaster-sec[.]cc ⭐ Credits: Likely related sample documented by @0xfluxsec via fluxsec.red/analysing-an-A… (but their AutoIt script does not seem to drop the Zig crypto clipper highlighted here)

User-reported phishing is one of the highest-volume, most time-consuming tasks a SOC team deals with. Most of what gets reported is benign. But the ones that aren't; demand fast and accurate triage. And that's exactly where the process tends to break down. zoom.us/webinar/regist… On March 24, join Serge Haumont from our team, for our March Detection & Intelligence Highlights webinar. The main demo: how VMRay's integration with Microsoft Defender for Office helps SOC teams efficiently investigate and manage user-reported phishing: cutting through the noise without cutting corners. Alongside that, Serge will walk through the latest detection innovations from VMRay Labs: 🔹 DLL injection detection: surfacing malware hiding inside trusted Windows processes 🔹 SyncAppvPublishingServer & ntdll.dll abuse: catching proxy execution used to evade monitoring 🔹 WMI uptime checks: detecting sandbox-aware malware before it goes quiet 🔹 ClickFix & pastejacking: AutoUI updates that automatically uncover social-engineering chains 🔹 New YARA rules & config extractors: expanded coverage across malware families Practical and to the point. Built for SOC analysts, CTI teams, detection engineers, and threat hunters. 🔗 zoom.us/webinar/regist…

🏛️ When you're defending a 100,000+ person organization, scaling security automation requires more than just connecting your tools: it requires reliable data. vmray.com/customer-succe… This major European government department had the orchestration in place: EDR, SOAR, Threat Intelligence Platform. But their automated workflows needed something more precise at the analysis layer. Standard sandboxing wasn't delivering the verdict accuracy, IOC quality, and clarity required to reduce manual review cycles at scale. They integrated @vmray as a specialized analysis component. Not to replace what they had built, but to make it work better. The result: significantly reduced manual triage, cleaner inputs into SOAR playbooks and SIEM, and an automation pipeline that could finally run at the pace the threat landscape demands. __________ The key takeaways from their deployment: 🔹 Evasion resistance is non-negotiable: You cannot automate a response to a threat you cannot fully observe. 🔹 Filter the noise: Standard sandboxes often output raw data dumps. True automation requires filtering out benign activity to produce automation-safe IOCs. 🔹 API-first orchestration: Intelligence must flow directly into existing playbooks to eliminate manual review cycles. __________ Full story → vmray.com/customer-succe…

Next week week, VMRay's CEO & Co-founder Dr. Carsten Willems and VP of Products Uriel Cohen will be at RSAC 2026 in SanFrancisco. 🤝 If you're a security leader or practitioner looking to exchange ideas on where threat intelligence and malware analysis are heading, or if you want to explore how to bridge the gap between deep technical analysis and operational clarity, we'll be there for exactly that. To keep leading innovation in cybersecurity built on community and collaboration. See you in San Francisco! 🌉

SANS Institute provides defenders with the tactical foundation to hunt and respond to threats. But applying those skills in a noisy environment requires the ability to reliably extract high-fidelity Threat Intelligence from evasive malware and phishing threats. Next week, we are heading to SANS 2026 in Orlando to discuss how teams can integrate evasion-resistant sandboxing and precise malware analysis directly into their daily workflows. If you are attending, let’s connect to talk about reducing manual triage, filtering the noise, and extracting the IOCs that actually matter.

🛡️ Malware doesn't announce itself. It blends in, using built-in Windows tools, trusted system components, and everyday traffic like DNS and image downloads to move quietly and stay hidden. Our February 2026 Detection Highlights documents exactly how: vmray.com/february-2026-… DNS lookups used to smuggle stolen data out. Legitimate Windows components like SyncAppvPublishingServer repurposed to launch malicious PowerShell. Security vendor domains silently redirected to nowhere, cutting systems off from the tools meant to protect them. In response, the VMRay Labs team shipped 8 new threat identifiers, expanded config extractors for Telegram-based phishkits and SantaStealer, improved ClickFix coverage in AutoUI, and added 30+ fresh YARA rules — covering stealers, RATs, loaders, packers, and phishing techniques. The full breakdown, with behavioral context on each detection, is in the link below. 🔗 vmray.com/february-2026-…

One of Europe's biggest cybersecurity gatherings is just around the corner. And we'll be there. 🇫🇷 VMRay is heading to InCyber Forum in Lille (31 March – 2 April). Come talk to us about what it actually takes to detect evasive malware and phishing threats, and build Threat Intelligence you can trust, not just collect. Find us at Lille Grand Palais. Let's connect. 🤝

In ThreatIntelligence, analyzing WHO is targeted often reveals the WHY behind a campaign. Our latest collaborative research by independent researcher Pol Thill reveals a highly structured, state-sponsored targeting matrix: Water utilities. Energy grids. Government agencies. Across 8 countries — and reconnaissance reaching 200+ more. This is the footprint of Hydra Saiga (also tracked as YoroTrooper / ShadowSilk) — a state-sponsored threat actor that has been quietly active since 2021, and shows no sign of slowing down. A clear pattern emerges from the victimology: 🔹 Strategic alignment: Heavy targeting of critical water and energy infrastructure in Central Asia. 🔹 Sector footprints: Unique industry focus by region—such as Water infrastructure exclusively in the CIS, and Aviation in the Middle East & Africa. For CTI and SOC teams, mapping these overlaps helps filter noise and prioritize defensive resources based on realistic risk profiles, rather than generic global alerts. Watch the global spread below. The full execution logic, and all extracted IOCs & TTPs (now available within the VMRay UniqueSignal Threat Intelligence Feed), are detailed in our complete analysis: 🔗 vmray.com/hydra-saiga-co…

🚨 Alert: Covert payload delivery through alternative object storage platforms 🔬Report: vmray.com/analyses/cover… 📦 In a newly observed attack chain, threat actors have started exploiting lesser known object storage platforms like cubbit[.]io or ufs[.]sh as disposable payload safehouses. 🥷 The chain starts off with an obfuscated VBScript, unfolding into an obfuscated PowerShell downloader. The PS1 script downloads a seemingly harmless image file, pulled from one of these object storage platform providers. Using simple steganography, a Base64 .NET Injector payload is concealed as appended bytes at the end of the image file. The smuggled .NET Injector is then reflectively loaded into RegAsm.exe and a final Agent Tesla payload is downloaded. This attack chain shows how modern delivery chains are constantly looking for alternative platforms to host and conceal their payload. 🔎 Key takeaways: - VBS → PS1 → GuLoader / Image (steganography) → .NET Assembly → Payload on cubbit[.]eu → RegAsm.exe → Agent Tesla -  Initial VBScript utilized junk code, Base64 obfuscation, word slicing, reverse string, and character substitution - Dropped PowerShell script (Base64 encoded), uses character replacement to thwart static analysis - Downloads a payload (usually GuLoader) from hosting site ufs[.]sh - Pulls an image file from firebasestorage.googleapis[.]com, which has a - Base64 blob at the end (steganography) - PowerShell parses the Base64 blob, decodes it and uses Reflection.Assembly to load the revealed executable (protected with SmartAssembly) - Dynamically locates a method named 'runss' on a type called 'Homees', invokes it with a remote payload hosted on cubbit[.]io - Injects the remote payload (Agent Tesla) into RegAsm.exe 🧬 IoCs: 1c216dc51330c5f56cc37f7e37b3516e57b172bd83f787788f80dcdb88b5545b hxxps://firebasestorage.googleapis[.]com/v0/b/remasd-6c702.firebasestorage.app/o/image.jpg?alt=media&token=b9d8bf3e-b1eb-4c56-9434-d4af570d4a91 hxxps://au72nuxzv2.ufs[.]sh/f/4LhV5B1sDCwIrgzpCwYKXE4gwWVSzU8Dck1rs5tJYqhnmpx6 hxxps://zip1.s3.cubbit[.]eu/SCANNED%20COPIES%20OF%20FINAL%20CONTRACT%20PDFupload.txt

🔥 Alert: New UmbralStealer variant, RahidStealer, spotted in the wild 📄 Report: vmray.com/analyses/rahid… RahidStealer is a newly observed infostealer variant closely related to UmbralStealer, focusing on credential harvesting and session theft from popular browsers, messengers, and gaming platforms, but also incorporating RAT-like features for remote control, and additional capabilities like MBR crippling and ransomware-like behavior achieved through manipulating boot configuration via bcedit. RahidStealer preserves UmbralStealer’s anti‑analysis characteristics such as virtual machine checks and abuse of Defender exclusions: the open-source nature of UmbralStealer allows threat actors to quickly change anything in the source code to alter the infostealer to their needs, allowing minor protocol and configuration changes. The developer - named Raxid - also offers a Downloader, a "BitJoiner", and a Crypter as separate programs. 💡 Key takeaways: - Malware config extracted, internal config is both Base64 obfuscated and AES-GCM encrypted - Sinkholes most AV/EDR vendor websites to 0.0.0.0 in /etc/hosts file - Uses WMI queries for system discovery (Win32_VideoController, Win32_DiskDrive, Win32_Processor, etc.) - Tries to detect sandbox/analysis environment (System Informer, Process Hacker, etc.) - Takes screenshot and disables Windows Task Manager - Changes Windows Defender settings to disable real-time monitoring - Reconfigures boot options via bcdedit.exeSets up scheduled task for persistence and places a hardcoded mutex - Exfiltrates the gathered data via either Telegram API or Discord Webhook IoCs: ee1ed16a95f403719260eaaa0de75e1b5d9210e6dcc8f66af8fb03253cd1ba21 (RahidStealer)13a5f1531e032e9ee4bf247ceff325077908c17eea7096dd6a7138c67eba5f82 (RaxidDownloader)e17bc55b0e5ff597820b1dd4e123dc750981d92d26b432117c707caad3fb9b58 (RaxidCrypter)c25a6eb11eec85b67bd7e253a3a06568fc97e8b3e57bba1b753254261ce31ac8 (BitJoiner)
