Kaspersky reports first known malware infecting Android car head units via firmware updaters, repurposing vehicles as BADBOX proxy nodes for ad fraud.
Kaspersky documented the first known malware infection of Android-based car head units, delivered through the built-in TWCore firmware updater on DoFun devices via an MQTT-driven installation flag. A multi-stage chain installs the JarService dropper and a loader that pulls a clicker and reverse proxy module ('zhima') used for ad fraud and proxy botnet infrastructure. The malware supports nine commands, including clipboard changes, HTTP requests, and JavaScript loading, checking in with C2 every 90 minutes. Kaspersky attributes the campaign with high confidence to MoYu Group, linked to the BADBOX botnet.
Head Mare exploits TrueConf server flaws to install web shells and deliver PhantomCore and PhantomGraph backdoors at Russian organizations.
Kaspersky detected July 2026 attacks by the threat actor Head Mare exploiting a vulnerability chain (KLCERT-26-057 and KLCERT-26-058) in unpatched TrueConf videoconferencing servers. The chain enables arbitrary code execution with SYSTEM privileges, deployment of a web shell at locale.php, and replacement of client installers with versions delivering the PhantomCore backdoor and PhantomGraph, which uses Microsoft OneDrive as C2. Targets span Russian instrumentation, electronics, transport, energy, IT, and software firms. Patches shipped in TrueConf Server 5.3.9, 5.4.9, and 5.5.5 on June 18, 2026.

Kaspersky researchers uncovered Android malware distributed through legitimate software for DoFun automotive head units. The malware displays ads on infotainment screens and enrolls infected devices into a proxy botnet for resale of residential-style proxy traffic. Delivery via trusted vendor software means victims receive it through a legitimate update channel, raising infection likelihood.
Kaspersky details Iranian Cavern Manticore's expanded C2 framework using DNS and Google Apps Script, plus APT42's TAMECAT spyware in nuclear-sector phishing.
Kaspersky reported new components in the Cavern (Cav3rn) C2 framework, used by Iranian MOIS-affiliated Cavern Manticore (with overlaps to MuddyWater and OilRig's Lyceum) against Israeli entities, monitored since December 2025. The new GoogleService.dll module performs DNS A-record queries to choose between direct HTTPS and a Google Apps Script relay per transaction, with the DNS infrastructure able to rotate the Google deployment ID; Kaspersky also found an inter-component broker (rnp.dll) and linked the framework's plugin-based pivot to late April 2026. Separately, Group-IB and Kaspersky detailed HOLLOWGRAPH, a .NET NativeAOT DLL first seen in the wild June 7, 2026, that uses Microsoft 365 calendar events via the Graph API as two-way dead drops dated May 13, 2050, with DNS tunneling refreshing Entra ID credentials. DarkAtlas also reported APT42's TAMECAT modular surveillance framework delivered via LNK masquerading as PDFs in spear-phishing targeting the nuclear energy sector in April-May 2026, with the group using generative AI to accelerate operations.
Mustang Panda's updated CoolClient backdoor deploys a signed kernel driver to hide processes, files and network activity in Asian intrusions.
Kaspersky analysis shows Mustang Panda (HoneyMyte) upgraded its CoolClient espionage backdoor with a signed kernel-mode driver installed as a Windows service, communicating via IOCTL requests to hide processes, files and registry entries. In a Myanmar campaign the actor deployed PlugX first, then CoolClient via a fake Windows Defender directory and Sangfor defender.exe DLL sideloading, with scheduled task and AutoRun persistence and UAC bypass. The updated variant was observed in intrusions across Pakistan, Mongolia and Myanmar, with victims also in Russia including confirmed government entities.
Kaspersky reports Mustang Panda's updated CoolClient backdoor now deploys a signed kernel-mode Windows rootkit, hitting government victims in Myanmar, Mongolia, Pakistan, and Russia.
Kaspersky identified a new CoolClient variant attributed to HoneyMyte (Mustang Panda) that installs a digitally signed Windows kernel driver, msagent.sys, to hide and protect malicious processes, files, registry keys, and C2 network information. CoolClient is consistently deployed as a secondary backdoor after PlugX, with confirmed victims including government entities in Myanmar, Mongolia, Pakistan, and Russia. In a Myanmar campaign, PlugX was used to deploy CoolClient via a renamed Sangfor executable for DLL side-loading, a scheduled task for persistence, and RPC-based process creation with PPID spoofing. The driver, signed with a 2013 certificate issued to Nanjing Ranyi Technology, implements 33 IOCTL handlers, process hiding via unlinking, a filesystem minifilter, and registry callbacks.
Kaspersky reports APT group HoneyMyte upgraded its CoolClient backdoor with a kernel-mode Windows rootkit hiding processes, files, and network connections.
Kaspersky researchers discovered a new variant of the HoneyMyte CoolClient backdoor equipped with a kernel-mode Windows rootkit driver.

Local Elevation of Privilege in Microsoft Defender Malware Protection Engine
CVE-2026-69414, publicly dubbed 'ShieldBreak', is a high-severity (CVSS 3.1: 7.8) elevation-of-privilege flaw in the Microsoft Malware Protection Engine (MMPE) that powers Microsoft Defender, rooted in improper access control and improper privilege management (CWE-284/CWE-269). It is triggered locally: an attacker who already holds low privileges on the machine needs no user interaction (AV:L/AC:L/PR:L/UI:N) to trip the engine's flawed access checks, and successful exploitation yields high impact to confidentiality, integrity, and availability. News coverage reports public PoCs released under the 'ShieldBreak'/'ShieldCrash' names demonstrating SYSTEM-level access on Defender-protected Windows systems, including claims that the shipped patch can be bypassed and arbitrary files read as SYSTEM. Because MMPE ships as the scan engine inside Microsoft Defender, effectively every Defender-protected Windows 10/11 endpoint and server is potentially affected, though the source data specifies no affected engine version ranges. There is no confirmed in-the-wild exploitation (EPSS 0.6%, absent from CISA KEV), but given the public PoC claims, defenders should assume working exploit code exists.

Unauthenticated RCE in Microsoft Remote Desktop Services (BlueKeep)
CVE-2019-0708 is a use-after-free (CWE-416) vulnerability in Microsoft Remote Desktop Services, formerly Terminal Services, in which an unauthenticated attacker can connect to a target system over RDP and send specially crafted requests to trigger the flaw. Because the trigger requires no authentication, the flaw is wormable: a successful exploit grants remote code execution on the target host, potentially with elevated privileges, and could allow self-propagating attacks similar to WannaCry. Organizations running the affected Microsoft Remote Desktop Services, particularly legacy Windows releases still accepting inbound RDP connections, are in scope. Exploitation is confirmed in the wild: the flaw (nicknamed BlueKeep) is listed in CISA's KEV catalog (added 2021-11-03), CISA notes known ransomware use, and EPSS assigns it a 100% probability of exploitation within 30 days.

Unauthenticated RCE in Gitea via diffpatch API Git Hook Injection
Gitea before 1.27.1 contains a critical code injection flaw (CWE-94) in the diffpatch API that allows remote code execution by causing the installation of a Git hook. An attacker can submit a crafted request through the diffpatch API to plant a Git hook, which then executes arbitrary shell commands on the server when Git operations run; the CVSS vector indicates the attack requires no authentication or user interaction, while public reporting describes attackers with repository write access planting hooks to run shell commands. Successful exploitation yields full server compromise (confidentiality, integrity, and availability all rated high), and observed attacks have reportedly dropped a cryptocurrency miner. All Gitea deployments running versions prior to 1.27.1 are affected, with internet-facing instances at greatest risk; public scans identified over 8,300 vulnerable Gitea servers. The flaw is actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-25, and EPSS estimates an 86.8% probability of exploitation within 30 days.

Code Injection Sandbox Escape in TrueConf Server Allows Host RCE via TCP 4307
TrueConf Server contains a code injection flaw (CWE-94) that allows a remote, unauthenticated attacker with network access to TCP port 4307 to send a specially crafted script that breaks out of the server's isolated environment and executes arbitrary code on the underlying host. The flaw affects TrueConf Server 5.3.X through 5.3.9, 5.4.X through 5.4.9, 5.5.X through 5.5.5, and earlier releases. A successful attack yields full code execution on the host system, not just the conferencing application, although the critical CVSS 4.0 score of 9.5 includes high attack complexity and attack-requirements factors. Organizations running self-hosted TrueConf video conferencing servers, especially those with port 4307 exposed to untrusted networks, are in scope. Exploitation is confirmed in the wild: CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-20, a public PoC exists, and Kaspersky's Securelist reports the Head Mare threat actor has actively targeted TrueConf Server to deploy PhantomCore malware.

Unauthenticated RCE in TrueConf Server via undocumented function on port 4307
CVE-2026-72529 is a missing-authentication vulnerability (CWE-306) in TrueConf Server that lets a remote, unauthenticated attacker reach an undocumented function over TCP port 4307 and execute an arbitrary script on the server. It is triggered simply by sending crafted requests to that port on an affected build, with no credentials or user interaction required. Successful exploitation yields code execution with high impact on the server's confidentiality, integrity, and availability (CVSS 4.0 base score 9.3). Any organization running TrueConf Server 5.3.x through 5.3.9, 5.4.x through 5.4.9, 5.5.x through 5.5.5, or earlier versions is affected. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-20, and a public Kaspersky (Securelist) report documents the Head Mare threat actor targeting TrueConf Server with the PhantomCore backdoor, confirming in-the-wild exploitation; EPSS currently estimates a 1.6% chance of exploitation in the next 30 days.

Unauthenticated OS Command Injection RCE in Synacor Zimbra Collaboration Suite
CVE-2026-73570 is an OS command injection vulnerability (CWE-78) in Synacor Zimbra Collaboration Suite (ZCS) before 10.1.20, caused by improper sanitization of untrusted input during SNMP notification processing. It is triggered when the optional zimbra-snmp package is installed and SNMP notifications are enabled: an unauthenticated attacker sends specially crafted SMTP requests that the flawed notification path turns into execution of arbitrary operating system commands. Successful exploitation runs commands as the Zimbra user, giving attackers control of the mail server's service account with high confidentiality and integrity impact across the host. Only ZCS deployments running the optional SNMP component with notifications enabled are vulnerable; other Zimbra installs are not exposed to this specific flaw. The flaw is under active exploitation: CISA added it to the KEV catalog on 2026-08-21, Poland's CERT has warned of in-the-wild attacks, unpatched Zimbra servers are reported compromised, and two public proof-of-concept exploits exist.

RCE in Microsoft Exchange Server from Shared Install-Time Validation Keys
CVE-2020-0688 is a remote code execution vulnerability in Microsoft Exchange Server caused by the validation key not being uniquely created at install time, leaving deployments with a predictable, shared key (CWE-287, improper authentication). A remote attacker who can reach an affected Exchange server and knows the common install-time key can supply maliciously crafted, cryptographically signed payloads that the server trusts, triggering code execution without needing per-server secrets. Successful exploitation gives the attacker code execution on the Exchange server, which can be used to access mail data, move laterally, and stage follow-on activity; CISA notes known use in ransomware campaigns. All organizations running the affected on-premises Microsoft Exchange Server are in scope per CISA's listing, though the affected version range is not specified in the source data. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2021-11-03 with known ransomware use, and EPSS rates 30-day exploitation probability at 100% (top percentile).

Memory Buffer Overflow in Citrix NetScaler ADC/Gateway Exploited in the Wild
CVE-2026-8452 is a memory buffer overflow (CWE-119) in Citrix NetScaler ADC and NetScaler Gateway that applies when the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, or RDP Proxy) or as an AAA virtual server. The flaw is reachable over the network without authentication (CVSS 4.0: AV:N/PR:N), so an unauthenticated attacker can trigger it remotely. Successful exploitation causes unpredictable or erroneous appliance behavior and denial of service, and the high confidentiality score suggests possible disclosure of memory contents; some reporting suggests pre-authentication remote code execution may be possible, though the vendor description emphasizes DoS. Organizations running affected NetScaler appliances in a Gateway or AAA role — a very common configuration for remote access to Citrix virtual apps and desktops — are potentially exposed. The flaw was added to CISA's KEV catalog on 2026-08-26 and is reported as exploited in the wild, with headlines noting the flaw was already patched before exploitation was confirmed.
