Crypto phishing apps on the Play Store

Over 20 malicious cryptocurrency phishing applications were identified on the Google Play Store, targeting users by impersonating popular wallets like SushiSwap and PancakeSwap. These apps steal users' mnemonic phrases, allowing attackers to access and drain cryptocurrency funds. They were distributed through compromised developer accounts and utilized phishing URLs embedded in privacy policies. The threat actors employed frameworks for rapid app deployment and operated a coordinated campaign linked to over 50 phishing domains. Some apps directly loaded phishing sites in WebView, further deceiving users into providing sensitive information.

Mirai exploits Wazuh vulnerability

Akamai detected active exploitation of the critical RCE vulnerability CVE-2025-24016 in Wazuh servers, with a CVSS score of 9.9. This vulnerability allows attackers to execute arbitrary code via unsanitized API requests. Two botnets, including a Mirai variant and the Resbot botnet, exploit this vulnerability to spread malware targeting IoT devices. CVE-2025-24016 affects Wazuh versions 4.4.0 to 4.9.0, with a fix available in version 4.9.1. The first botnet uses shell scripts to download and execute Mirai malware payloads named "morte," targeting various architectures. The second botnet, Resbot, uses Italian-themed domains and targets IoT devices with its payload named "resgod."

SoraAI branding used for malware distribution

Malicious actors are exploiting the popularity of OpenAI's SoraAI and using GitHub to distribute malware disguised as a shortcut file named SoraAI.lnk. This multi-stage attack chain employs social engineering tactics to steal sensitive data, leveraging trusted platforms and tools to evade detection. The malware extracts browser cookies, passwords, system information, and more, with exfiltrated data sent via Telegram and GoFile[.]io.

Fog ransomware operators are blurring the line between admin tools and attack chains. In a recent incident, they deployed a mix of open-source and legitimate software to gain persistence and exfiltrate data undetected. The attack combined tools like Stowaway, Impacket, and 7-Zip to move laterally and quietly siphon off sensitive information. A flaw in Secure Boot could let attackers hijack your system before the OS even loads. It affects the UEFI firmware layer and allows unsigned code execution during boot, leading to persistent malware installation. The issue stems from a vulnerable BIOS flashing utility signed by Microsoft, raising concerns about trusted bootchain integrity. Legitimate testing tools are being twisted into powerful attack platforms. A campaign, dubbed UNK_SneakyStrike, has been using the TeamFiltration tool to compromise Microsoft Entra ID accounts and exploit services like OneDrive and Teams. Over 80,000 accounts have been targeted since late 2024, with activity tied to AWS-hosted infrastructure.

Hidden behind obfuscated code and automated workflows, the campaign deploys backdoors while using Telegram bots and paste sites to manage infections behind the scenes. Destruction masquerading as maintenance tools is hitting Ukraine’s infrastructure. Researchers attributed a new wiper malware called PathWiper to a Russia-linked APT group, targeting critical systems by leveraging legitimate administrative frameworks. The malware erases storage media and key file system data. Though reminiscent of HermeticWiper, PathWiper shows a more advanced method of drive targeting and destruction. Cisco is closing two critical gaps before attackers can exploit them further. A patch has been issued for CVE-2025-20129 in Cisco’s CCP chat interface, a flaw that could let attackers intercept sensitive data through manipulated HTTP requests.

Cybercriminals are turning CAPTCHA prompts into malware gateways. A recent multi-stage malware campaign is using spoofed sites like fake Git repositories and bogus Docusign pages to lure users into executing PowerShell scripts that drop NetSupport RAT. By layering downloaders that each fetch the next stage, the attackers dodge detection and prolong infection. In a similar vein, a free software download could end up costing your entire crypto wallet. ViperSoftX is back in circulation, targeting crypto users with malicious PowerShell scripts bundled into cracked apps, keygens, and torrent packages. Beyond wallet theft, it pulls in additional payloads like Quasar RAT and PureHVNC, while using scheduled tasks and registry tricks to quietly maintain persistence. Meanwhile, Google’s June 2025 Android security update fixed a slate of high-severity issues, including a critical privilege escalation vulnerability in the System component affecting Android 13, 14, and 15. While most bugs haven't been exploited in the wild, three Qualcomm-related flaws made it to CISA’s KEV Catalog. For detailed Cyber Threat Intel, click ‘Read More’.

A casual scroll through gaming forums or social media might land users in a trap they didn’t see coming. Cybercriminals are hijacking web traffic to lure users onto fake Booking[.]com sites with malicious CAPTCHA prompts that silently trigger harmful commands. The URLs shift constantly, and any site asking users to paste clipboard commands should raise serious red flags. A few swapped letters could be all it takes to get owned. A new supply chain attack targets Python and npm developers through typo-squatting and name confusion. The campaign spans both ecosystems, dropping platform-specific payloads that harvest environment data, evade antivirus tools, and create persistence. What began as one bug unraveled into a deeper security mess. Researchers uncovered multiple privilege escalation flaws in SonicWall’s NetExtender VPN client, letting local users achieve SYSTEM-level access or sabotage services. The discovery of CVE-2025-23007 led to a deeper dive, exposing two more high-risk vulnerabilities now patched in version 10.3.2.

Fake CAPTCHA prompts are now doing more than testing if you're human—they're installing malware. EDDIESTEALER, a new Rust-based infostealer, spreads through deceptive CAPTCHA pages that trigger malicious PowerShell scripts. The malware downloads obfuscated JavaScript and executable payloads designed to harvest credentials, browser data, and cryptocurrency wallets. A quiet but relentless campaign has been unfolding across multiple industries. The Chinese group Earth Lamia is targeting finance, government, logistics, and more by exploiting known web app vulnerabilities, including flaws in Apache Struts, GitLab, and WordPress. After gaining access, they deploy webshells, create admin accounts, and move laterally using a plethora of tools. Even Google's trusted ecosystem isn’t off-limits anymore. Attackers are misusing Google Apps Script to host phishing pages that convincingly imitate real login portals. The method allows them to slip through email filters by operating under Google's domain, tricking victims into handing over credentials before redirecting them to legitimate sites to avoid suspicion.

APT41 hides malware commands where no one’s looking: your calendar. In a creative twist on C2 infrastructure, China-backed APT41 embedded encrypted instructions inside Google Calendar events. Targets received ZIPs masquerading as PDFs, which deployed a multistage malware suite. The result: stealthy, long-term access across governments and industries. AyySSHush doesn’t make noise, it builds armies. More than 9,000 ASUS routers have been compromised by this botnet, which quietly slips in through a CVE-2023-39780 exploit. Attackers install persistent SSH backdoors, disable logging, and remain invisible through firmware updates. The campaign’s low network footprint hides a growing infrastructure of hijacked devices ready for future use. OneDrive’s permissions flaw lets apps peek at everything. A design issue in Microsoft’s OneDrive File Picker lets apps access more data than intended. Vague consent prompts and overly broad OAuth scopes mean entire OneDrive contents could be exposed. Microsoft hasn’t patched it yet, so users should tread carefully.
