The GreedyBear attack group has launched a massive crypto theft operation, utilizing 150 weaponized Firefox extensions, nearly 500 malicious executables, and numerous phishing websites. Their tactics include Extension Hollowing to bypass marketplace security, distributing various malware families, and creating scam sites masquerading as crypto products. The campaign's infrastructure is consolidated to a single IP address, suggesting a centralized backend. The group has expanded from its earlier Foxy Wallet campaign and shows signs of potential growth beyond Firefox. The attackers are leveraging AI to scale their operations, making it challenging for traditional security measures to keep up. The campaign has reportedly stolen over $1 million from victims.
A new DarkCloud campaign was observed in July 2025, targeting Windows users with a sophisticated infection chain. The attack begins with a phishing email containing a RAR archive, which leads to the execution of obfuscated JavaScript and PowerShell code. This code downloads and deploys a fileless .NET DLL, which in turn downloads and injects the DarkCloud payload into a legitimate Windows process. The DarkCloud variant, written in Visual Basic 6, employs anti-analysis techniques and collects sensitive information from various sources, including web browsers, email clients, and FTP clients. The stolen data is exfiltrated via SMTP. The campaign demonstrates advanced evasion techniques and targets a wide range of user credentials and personal information.
Akira affiliates have been observed exploiting two common drivers as part of a suspected AV/EDR evasion effort following initial access involving SonicWall abuse. The drivers, rwdrv.sys and hlpdrv.sys, are being used to facilitate AV/EDR evasion or disablement through a Bring Your Own Vulnerable Driver (BYOVD) exploitation chain. This behavior has been prevalent in recent Akira ransomware incident response cases. The campaign may be driven by an unreported zero-day vulnerability in SonicWall VPNs. Defenders are advised to harden SonicWall VPNs, implement recommended mitigations, and use provided YARA rules for detection and response to pre-ransomware activity.
A phishing campaign targeting macOS users employs a ClickFix technique to deliver the Odyssey Stealer malware. The attack uses a fake CAPTCHA verification page that executes without dropping a binary on the system. When users follow the instructions, they unknowingly execute a malicious AppleScript that collects sensitive data, including crypto wallet information, browser extensions, cookies, saved keychains, usernames, and passwords. The script creates a ZIP archive of the stolen data and exfiltrates it to a command and control server. This sophisticated attack blends phishing and social engineering to bypass traditional detection methods, making it challenging to detect and analyze.
These indicators of compromise (IOCs) were identified through LevelBlue Labs' proprietary collection and threat hunting processes, leveraging AI-driven heuristics to detect anomalous patterns, behavioral analysis of malicious activity, and cross-referenced intelligence from endpoint telemetry and external sources. The IOCs included in this pulse are associated with command and control (C2) infrastructure, facilitating malware communication, data exfiltration, and persistent threat actor operations. Use this data to enhance detection rules, block malicious infrastructure, or correlate with existing incident investigations.
A series of cryptocurrency scams have been uncovered where threat actors distribute malicious smart contracts disguised as trading bots to drain user wallets. The campaign has stolen over $900,000 US and employs multiple obfuscation techniques to conceal the attacker's wallet address. Leveraging aged YouTube accounts and curated comment sections, the scams create a false sense of legitimacy. The smart contracts, written in Solidity, use various methods to hide the attacker's Externally Owned Account. Distribution occurs through YouTube videos explaining the contracts as trading arbitrage bots, with some videos showing signs of being AI-generated. The most successful scam yielded approximately $902,000 US from a single attacker address.
A potential zero-day vulnerability in SonicWall VPNs is being actively exploited to bypass MFA and deploy ransomware. The attack chain begins with a breach of the SonicWall appliance, followed by post-exploitation techniques including enumeration, detection evasion, lateral movement, and credential theft. Attackers quickly gain administrative access, establish command and control, move laterally, disable defenses, and deploy Akira ransomware. The threat actors use a mix of automated scripts and manual activity, abusing privileged accounts and utilizing various tools for persistence and data exfiltration. Immediate action is advised, including disabling SonicWall VPN access or severely restricting it, auditing service accounts, and hunting for malicious activity using provided indicators of compromise.
This analysis explores the sophisticated tactics employed by LockBit ransomware attackers, focusing on DLL sideloading and masquerading techniques. These methods allow attackers to evade detection and maximize impact. DLL sideloading involves tricking legitimate applications into loading malicious DLLs, exploiting trusted programs. Masquerading tactics include renaming malicious files, spoofing process names, and using legitimate icons to blend in with system processes. Recent attacks have utilized trusted applications like Jarsigner.exe, MpCmdRun.exe, and Clink_x86.exe alongside malicious DLLs. The attack chain encompasses initial access, privilege escalation, discovery, credential theft, lateral movement, and impact stages. Attackers employ various tools and techniques, including remote desktop access, NSSM, PsExec, and PowerShell scripts for file encryption.
NOVABLIGHT is a NodeJS-based Malware-as-a-Service (MaaS) information stealer developed by a French-speaking threat group. It's sold as an educational tool but used for credential theft and cryptowallet compromise. The malware features heavy obfuscation, multiple anti-analysis techniques, and various data exfiltration methods. It can disable Windows Defender, sabotage system recovery, and inject malicious code into popular Electron-based applications. NOVABLIGHT employs comprehensive system enumeration, captures screenshots and webcam footage, and steals passwords from various sources. The threat actors use Telegram and Discord for sales and support, with licenses valid for up to a year.

A sophisticated malware campaign called JSCEAL is targeting cryptocurrency users through fake apps impersonating popular trading platforms. The attackers use malicious ads to lure victims into downloading installers that deploy a multi-stage infection chain. This includes PowerShell scripts for profiling and a final payload of compiled JavaScript (JSC) files executed via Node.js. The JSCEAL malware steals crypto-related data and credentials while employing advanced evasion techniques. The campaign has potentially reached millions of users across multiple countries, primarily targeting the cryptocurrency and financial sectors.
