Cavern C2 Uses DNS and Google Apps Script to Blend Into Legitimate Traffic

Cybersecurity researchers have traced the continued evolution of the Cavern (aka Cav3rn) command-and-control (C2) framework used by Iranian nation-state hackers in attacks targeting entities in Israel. Russian cybersecurity company Kaspersky said its ongoing monitoring of the threat activity cluster since December 2025 has led to the discovery of previously unreported components that expand the toolkit's communication capabilities. "The main finding is a complex C2 module that uses DNS A-record responses to choose between direct HTTPS and a Google Apps Script relay for each transaction," Kaspersky said in an analysis. "The same DNS infrastructure can validate and replace the relay deployment ID, allowing the operator to rotate the Google channel." Cavern, first publicly documented by Check Point Research in early July 2026, consists of multiple moving parts, including an Agent and an assortment of modules, that work in tandem to enable mission-specific...

⚡ Weekly Recap: VMware Exploits, Windows 0-Day, MCP Attacks, Browser Hijacks and More

The expensive attacks are not always the clever ones. This week had plenty of proof. Exposed services got hit, old bugs found fresh use, browser sessions became attack paths, and supply-chain problems kept spreading farther than the original compromise. A lot of it came down to access that was already there and defenses that assumed nobody would look too closely. So, nothing magical. Just a lot of small openings turning into bigger problems. Here’s what stood out. ⚡ Threat of the Week Suspected China APT Behind Exploitation of New VMware Flaw — A suspected China-nexus APT is assessed to be behind the exploitation of a newly patched security flaw in VMware vCenter. The attacks involve the exploitation of CVE-2026-59310 (CVSS score: 9.8), a severe directory-traversal vulnerability in the VMware vCenter server that could be weaponized by a malicious actor to execute arbitrary code. In at least one compromised instance, the attacks led to the deployment of a backdoor and. a rever...

How MCP Servers Can Expose Enterprise Secrets

MCP servers can expose enterprise secrets through plaintext configuration files, over-permissioned access and prompt injection, often before security teams even know the server is running. As more organizations adopt AI agents into their systems, that exposure can silently become a major gap in MCP server security. The Model Context Protocol (MCP) allows AI agents to reach the tools and data, including internal documentation and cloud infrastructure, that form the foundation of enterprise systems. Behind that convenience, the MCP server connecting those tools and data to enterprise systems typically holds the keys to everything it touches: credentials, service account keys, API tokens and other secrets. Every organization should now question what secrets they are handing to AI and how well those secrets are protected once they reach an MCP server. What is Model Context Protocol (MCP)? Model Context Protocol (MCP) is an open standard, originally introduced by Anthropic, that allows...

Unisoc VoLTE Video Call Exploit Chain Can Give Attackers Full Android Kernel Access

Security researchers at SSD Secure Disclosure have published a two-stage exploit chain that achieves full Android kernel access on devices running Unisoc modem firmware through a VoLTE video call, with no fix from the chipset maker. The  advisory , published August 17, 2026, is the second stage of a chain that began in March 2026, when SSD disclosed  remote code execution  in the same firmware through a malformed SIP video call. Completing the full chain requires the attacker to control a private 4G cellular network and the victim to answer the incoming video call. "We have tried to reach out to the vendor through multiple channels (email and LinkedIn) but have not been able to receive any response," SSD Secure Disclosure said in its advisory. The March 2026 disclosure carried the same statement. The research was carried out by an independent security researcher using the handle 0x50594d. The privilege-escalation vulnerability is classified as CWE-1189, Improper ...

Evooo1Bot Linux Botnet Exploits Known Flaws to Turn Edge Devices Into SOCKS5 Proxies

Cybersecurity researchers have flagged a previously undocumented Linux botnet family dubbed Evooo1Bot that derives its core functionality from the Mirai botnet source code and is equipped to turn internet-facing devices into SOCKS proxies. "While the malware reuses the DDoS engine from the publicly leaked Mirai source code, it extends the original framework with numerous capabilities, including encrypted C2 communications, an SSH brute-force scanner, a SOCKS relay module, a credential sniffer, and an integrated exploit arsenal targeting multiple known vulnerabilities," Fortinet FortiGuard Labs said . Evidence indicates that the botnet has been active in the wild since July 2026, exploiting known vulnerabilities in publicly-accessible devices to deliver the malware. Some of the security flaws weaponized by the botnet are below - CVE-2007-3010 - Alcatel OmniPCX Enterprise Remote Code Execution Vulnerability CVE-2016-6277 - NETGEAR Multiple Routers Remote Code Ex...

Suspected China-Nexus Actor Exploits VMware vCenter Flaw, Deploys Babuk-Derived Ransomware

Cybersecurity researchers have attributed the exploitation of a newly patched security flaw in Broadcom VMware vCenter to a suspected China-nexus advanced persistent threat (APT). The attacks involve the exploitation of CVE-2026-59310 (CVSS score: 9.8), a severe directory-traversal vulnerability in the VMware vCenter server that could be weaponized by a malicious actor to execute arbitrary code. A fix for the flaw was released by Broadcom on July 29, 2026. German incident response company QUIRSO assessed with moderate confidence that the exploitation campaign aimed at CVE-2026-59310 is operated by a Chinese-speaking threat actor, likely working in the UTC+08:00 time zone, which is predominantly used in Chinese-speaking regions. "This assessment is based on the convergence of Chinese-language artifacts in attacker-created scripts, apparent reuse of research from a Chinese security publication, repeated operational use of Chinese-language tools and management software, victi...

SAP Commerce Cloud CVE-2026-58231 Targeted in Exploitation Attempts Days After Patch

A maximum-severity security vulnerability impacting SAP Commerce Cloud is witnessing active exploitation efforts. The vulnerability, tracked as CVE-2026-58231 , is rated 10.0 on the CVSS scoring system. It relates to an instance of insufficient authorization checks and input validation. "SAP Commerce Cloud allows an unauthenticated attacker to abuse a default authentication client and submit specially crafted input to certain functions lacking sufficient validation," per CVE.org. "Successful exploitation could enable arbitrary code execution and compromise internal components, resulting in high impact on confidentiality, integrity, and availability of the application." According to Defused Cyber, exploitation attempts against CVE-2026-58231 began to hit its honeypot systems merely three days after the release of the patch. "This vulnerability has no public PoC and is not known to be exploited," the threat intelligence company said in an X post ...

Apple macOS Screen Sharing Flaw Exploited on Internet-Exposed Macs to Install Monero Miner

A recently patched security flaw in Apple macOS has come under active exploitation in the wild to deploy a cryptocurrency miner, the Netherlands National Cyber Security Centre (NCSC-NL) has warned . The vulnerability in question is CVE-2026-65400 (CVSS score: 9.8), a critical authentication issue impacting the Screen Sharing component that could allow an attacker already on the network to authenticate to the built-in remote desktop feature service without valid credentials. The updates released by Apple improve state management mechanisms to enforce correct credential validation and prevent unauthorized authentication attempts. The shortcoming was addressed as part of an emergency update in macOS Tahoe 26.6.1 , macOS Sequoia 15.7.9 , and macOS Sonoma 14.8.9 earlier this month. "An authentication issue was addressed with improved state management," Apple said in an advisory released on August 6, 2026. It credited security researcher Alfredo Pesoli of Bynario for disco...
