A supply-chain attack targeting Android-based car head units is using a legitimate device-update app to spread malware that enlists compromised devices in a proxy botnet or uses them for ad fraud. Kaspersky researchers analyzed the malware and attributed the operation to the MoYu group, a threat actor previously associated with the BadBox malware botnet. The researchers note that this is the first documented case of a malware infection chain specifically created for the targeted car head unit. MoYu's operation targets systems from DoFun, a Chinese automotive software and hardware provider owned by Shenzhen Driving Control Technology Co., Ltd. DoFun is an automotive software, cloud services, and hardware provider that sells generic Android-based head units, which act as the command center for a car's infotainment, navigation, and settings systems.
Windows named pipes provide fast interprocess communication, but weak access controls can expose privileged services to untrusted processes. ThreatLocker explains how endpoint verification, command authorization, strict input validation, and narrowly scoped privileges can help secure named-pipe communication.
Malware is abusing car infotainment updates to install proxy software, turning Android head units into nodes for the BADBOX network. Kaspersky researchers found something in June 2026 that made them stop and look twice: an Android app with no interface at all, installed like any ordinary app but making zero effort to disguise itself as legitimate. Their report documents the first known malware infection targeting car head units, the Android-based infotainment and control systems built into many modern vehicles, spread through the vehicle’s own official update mechanism. Head units run Android for practical reasons, since manufacturers can build on existing source code and add their own custom system apps during production. That flexibility cuts both ways. Because head units are just Android devices under the hood, most apps built for smartphones can technically run on them too, including malware, even though something like a banking trojan would be wasted effort on a device nobody uses for mobile banking. Kaspersky researchers found something unusual in June 2026: an Android app with no visible interface that was installed like a normal app but did not try to look legitimate. Their report describes what they say is the first known malware infection targeting car head units, Android-based systems used for infotainment and vehicle controls, delivered through the car’s official update system. “We identified new Android malware: a multi-stage downloader whose ultimate purpose is ad fraud and creation of a proxy botnet.” reads the report published by Kaspersky. “The malware spread through the built-in updaters of Android-based automotive head unit firmware. This is the first documented case of malware found on a car head unit with an infection chain specific to that type of device.” Car head units often use Android because it is flexible and lets manufacturers add their own software. But this also creates a security risk. Since these systems are basically Android devices, many apps designed for smartphones can also run on them, including malware. The infection chain here starts inside TWCore, a completely legitimate system app responsible for analytics and firmware updates on DoFun head units. An MQTT message broker sends TWCore instructions about which APK files to download and install, and a specific configuration flag called installNotExists controls whether the app checks if something is already installed before pushing it. “TWCore only checks whether an app is already installed on the device when installNotExists = false The APK file is downloaded to <TWCore external cache dir>/push/apk/ for installation.” which means setting that flag the other way turns a routine update channel into a silent installation pipeline for anything the attackers want to push. What gets installed through that channel is a small dropper called JarService, carrying zero user interface and doing nothing but decrypting and loading the next stage. That stage is a loader that phones home to a command server, reports basic device details, and receives a download link for the actual payload, a third-stage module researchers found could be pulled in at least seven different versions simply by trying different version numbers in the download URL. That third stage turns out to be a clicker and reverse proxy component, checking in with its server every 90 minutes by default and waiting for new instructions. “In this stage, the malware sends a POST request to /cpc/api/task every 90 minutes by default, containing information about the infected device (display resolution, device model, the SSID of the connected Wi-Fi network, MAC address, and so on) along with the Trojan’s configuration version.” continues the report. “If the configuration is outdated, the C2 server returns an updated configuration containing new C2 addresses and new paths for sending HTTP requests.” The command system behind the malware is more powerful than you might expect from something running silently on a car’s dashboard. Researchers found nine commands, including ones that can change the clipboard, send HTTP requests, load web pages, and run JavaScript. In practice, attackers mainly used two: one to download and run new code, and another to send web requests. The extra module they deployed, called “zhima,” was a reverse proxy. This means the main goal was not to attack or control the car. Instead, the attackers wanted to use infected cars’ internet connections as part of a larger proxy network. Tracing the malware’s naming conventions and infrastructure led researchers to attribute the campaign, with high confidence, to MoYu Group, an actor connected to the BADBOX botnet that’s been documented previously by other researchers. A thread inside the second-stage loader carried the internal name “mosdk-host-loader,” which pointed toward malware previously found on TV set-top boxes tied to the same group, and overlapping network infrastructure independently spotted by a separate research team around the same time backed up the connection.

This means the main goal was not to attack or control the car. Instead, the attackers wanted to use infected cars’ internet connections as part of a larger proxy network. There is also a strange detail in the network’s infrastructure. The proxy service’s admin panel allows people to create accounts if they have a valid invite code. Its copyright text and login page also look similar to those used by at least two commercial residential-proxy services. This suggests the network may be linked to a business-like proxy service, while also using infected cars to provide internet connections. BADBOX has survived several takedown attempts by researchers and law enforcement. This campaign shows why: the people behind it keep changing how they spread the malware and are moving into new types of devices. Cars are now joining smart TVs and set-top boxes as devices that can be quietly added to a botnet. As cars become more like computers, they also need the same kind of security protection.

A critical flaw (CVSS 9.4) in NASA/JPL’s AIT-GUI let anyone send unauthenticated commands to spacecraft instruments. Cycode researchers found that AIT-GUI, the browser-based operator console in NASA/JPL open-source AMMOS Instrument Toolkit, shipped with no authentication, no session checks, and no CSRF protection on any of its state-changing endpoints. “AIT-GUI, the web front end of NASA/JPL’s open-source AMMOS Instrument Toolkit, starts an HTTP server with no authentication, no authorization, and no CSRF protection on any of its state-changing endpoints.” reads the report published by Cycode. “Anyone who can reach the port, or any website an operator merely visits in a browser, can: Issue arbitrary commands via POST /cmd Run server-side scripts via POST /script/run Execute command sequences via POST /seq“ The vulnerability is tracked as GHSA-p9r8-2q67-fp86, rated Critical (CVSS score of 9.4), and fixed in AIT-GUI 2.5.2. AMMOS (Advanced Multi-Mission Operations System) is an open-source framework used by NASA/JPL and other missions to control spacecraft and instruments, send commands, and process the data they send back. AIT-GUI is the web interface operators use to do this in real time. Sending a command through this software is not like filling out a simple online form. The vulnerability isn’t one thing. It’s four ordinary web weaknesses that compose into something with unusual consequences. The first is that the server reads its configured host setting into a variable and then ignores it, binding instead to 0.0.0.0, which means all network interfaces. An operator who sets host: localhost to keep the console on the loopback gets a server exposed to the entire reachable network anyway. The second and third weaknesses follow from the first. There’s no login requirement, no session gate, no CSRF token, and no cross-origin restriction on any route. POST /cmd takes whatever arrives in the command field, parses it, and hands it directly to the command bus: no check, no validation, nothing between the network and the hardware. The fourth weakness lives on POST /seq and POST /script/run, which build filesystem paths by joining raw user input onto a root directory with no confinement. A seqfile value of ../../../../something resolves outside the intended sequence directory. The researchers note that the correct confinement check already exists in the same codebase, on a sibling route called /scripts/load; the safe pattern was already written, just not applied consistently. The CSRF risk is especially serious because a firewall does not stop it. Browsers can send certain form requests from another website without first checking with the target site. So, if an operator opens a malicious page in the same browser they use for the console, it could send commands such as POST /cmd, POST /seq, or POST /script/run. The attacker does not need direct access to the system or its network port—they only need the operator to open a malicious link. Cycode’s research team used a combination of AI-assisted code analysis and human validation to find and confirm the issues. The AI handled the initial codebase review, flagging recognizable patterns: state-changing routes with no auth anywhere in their call path, user input flowing from a request parameter into a subprocess call without sanitization, and a configuration value that was read and then silently discarded. The human researcher then confirmed each pattern was exploitable and reduced each to a working proof-of-concept, including a self-contained CSRF demonstration that drove a real headless browser and recorded zero network preflights. That second step matters. A pattern match points to a candidate; a reproduced exploit confirms the finding is real. Cycode says explicitly it only reports the second kind. “More broadly: operational and ground-system software inherits the same web weaknesses as everything else, but with a far higher cost of failure. Auth, CSRF defense, and input confinement are not optional extras on a panel that commands hardware.” concludes the report. The fix is in AIT-GUI 2.5.2. Operators should upgrade immediately and verify the console port is not reachable from untrusted networks. Anyone who ran an exposed instance before the patch should treat it as a reason to audit command and sequence history, since an unauthenticated POST leaves no user-level trace by design. Maintainers hardening deployments should add authentication and CSRF protection to the command, script, and sequence routes; bind the server to the configured host instead of 0.0.0.0; and apply the existing path-confinement logic from /scripts/load to /seq and /script/run.

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Zimbra Collaboration Suite (ZCS) flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the Zimbra Collaboration Suite (ZCS) flaw CVE-2026-73570 to its Known Exploited Vulnerabilities (KEV) catalog. CERT Polska, Poland’s national computer emergency response team, confirmed this week that threat actors are actively exploiting the critical vulnerability in Zimbra Collaboration Suite. The flaw allows unauthenticated remote code execution and was patched less than a month ago. “The CERT Polska team informs about an actively exploited OS Command Injection vulnerability in Zimbra Collaboration Suite.” reads the advisory published by CERT Polska. “The vulnerability, identified as CVE-2026-73570 , allows an unauthenticated attacker to execute arbitrary shell commands with the privileges of the zimbra user . The vulnerability affects instances that have the SNMP trap service enabled via the snmp_notify parameter and the swatchdog service running (enabled by default).” The vulnerability affects systems with SNMP trap notifications enabled and the swatchdog service running, which is enabled by default. The technical root cause is a sanitization failure in the SNMP monitoring component. Zimbra released version 10.1.20 on 20 July 2026 to address the issue. The fix came 28 days before active exploitation was confirmed, which is not a wide window, but apparently wide enough. The attack surface only exists when the optional zimbra-snmp package is installed and SNMP notifications are active, but swatchdog, the service that processes those notifications, is running by default on most installations. Below are recommendations by CERT Polska: “Due to the ongoing campaign exploiting this vulnerability, we recommend: verifying Zimbra logs /var/log/zimbra.log for the following entries: Service status change: <szkodliwy ładunek> changed from stopped to running Service status change: <szkodliwy ładunek> changed from running to stopped verification of files created by user zimbra in the last 30 days in the following directories: /opt/zimbra/jetty/webapps/ /opt/zimbra/jetty_base/webapps/ /tmp/ If you discover any signs of potential exploitation of this vulnerability, please contact our team immediately.” According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaw by August 24, 2026.

UMass Amherst researchers showed expired Visa contactless cards can make real purchases by exploiting an unsigned expiry field in Visa’s EMV kernel. Researchers at the University of Massachusetts Amherst demonstrated at USENIX Security 2026 in Baltimore that expired Visa contactless credit cards can complete real purchases, including transactions at live retail and grocery merchants, by exploiting a gap in how the payment protocol handles expiration dates. The paper is titled “Zombie Cards Back Online: Reviving Expired Credit Cards for Contactless Payments,” and the name is accurate. Raja Hasnain Anwar, Gerard DeCunha, and Muhammad Taqi Raza built the attack around a structural weakness in EMV, the contactless payment protocol used by Visa, Mastercard, American Express, and Discover. “A central source of fragility is that the EMV contactless protocol is a selectively authenticated transaction flow. Many data objects are exchanged in plaintext between the card and terminal [2], and only a subset is later bound to cryptographic verification via Offline Data Authentication (ODA) and issuer-verified cryptograms.” reads the paper. “In consequence, an adversary who obtains a man-in-the-middle position on the NFC channel can tamper with decision-critical fields that are consumed by the terminal but are not end-to-end integrity protected. Prior NFC attacks [10–12, 44], including relay-based manin-the-middle techniques, exploit this gap by manipulating transaction-relevant objects in transit while leaving cryptographic checks intact.” The attack exploits a specific design decision in Visa’s Kernel 3, the software layer that implements the EMV protocol for Visa transactions. A Visa contactless transaction presents the expiration date twice: once in a field the payment terminal reads (tag 5F24, the Application Expiration Date) and once in a field the issuing bank reads (tag 57, Track 2 Equivalent Data). These two representations should be tied together by a cryptographic signature, but in Visa’s implementation they aren’t. The relay attack changes only the expiry date that the payment terminal sees, replacing it with a future date while leaving the data sent to the bank unchanged. The card’s digital signature remains valid because it does not cover the expiry date. As a result, the bank receives a transaction that appears legitimate and passes its normal security checks. In simple terms, an attacker can change the expiry date between the card and the terminal without breaking the card’s cryptographic protection. The relay itself is two NFC-capable Android phones running custom software over Wi-Fi: one emulates a card, one emulates a terminal. Each communication round trip added roughly 20 milliseconds for relay alone and about 50 milliseconds with the date modification, keeping the per-transaction average around 415 milliseconds, within Visa’s 500-millisecond command limit. None of the test hardware used EMV’s optional Relay Resistance Protocol, which would have detected the added latency by bounding permissible response times. Mastercard, American Express, and Discover all blocked the attack. Mastercard’s terminal checks consistency between the two expiry representations during record parsing and treats a mismatch as a card data error. American Express binds the expiration date into the data covered by offline authentication, so a modified value produces a hash mismatch. Discover’s kernel wraps the modified transaction objects into the verified transaction hash, and those also failed. Visa’s Kernel 3 does none of these things. The outcome also depended on the issuing bank. The researchers tested three banks with expired and replaced physical Visa cards and found three distinct policies, not a clean pass or fail split. Bank A accepted the modified transactions at $1.00, $100.00, and $500.00 in the lab, and completed purchases of $2.79 at a retail merchant and $3.19 at a grocery merchant on campus. Bank A also accepted transactions from both the expired original card and its replacement against the same account simultaneously, a separate finding that Anwar described as alarming. Bank B detected the modification but still accepted some transactions. A third bank tested on Discover’s kernel detected the edit and declined; however, it also showed the simultaneous-card problem without any modification at all. There is another finding that makes the issue more serious. Researchers changed the Consumer Device Cardholder Verification Method flag at five US banks, and the transactions worked at most of them. This flag controls how the terminal verifies the cardholder, and attackers can change it because the payment data can be modified while it travels between the card and the terminal. There is also another problem with Kernel 3. It sends the issuer a Terminal Verification Results value filled with zeros. This means the bank cannot tell whether the terminal checked the card’s expiry date or whether that check failed. The bank must therefore approve the transaction without seeing what the terminal actually detected. “Across all tests, the dominant factors that determine attack success or failure are: (i) the EMV kernel in use and whether expiry data fields are cryptographically bound to authenticated protocol outputs; (ii) issuer-side lifecycle enforcement, especially whether authorization is tied only to the active account and PAN or also to the specific card instrument and expiration date; and (iii) whether terminal-side validation results are visible to the issuer via TVR. In contrast, transaction amount1 , merchant category, and POS terminal brand did not independently determine the transaction outcome.” continues the paper. The researchers disclosed the findings to Visa in May 2025 and followed up in December 2025. The paper records that Visa acknowledged the report, said it passed initial triage, and indicated it was undergoing reproduction by Visa’s red team. No CVE has been assigned. Neither Visa nor any of the notified banks confirmed any mitigation as of the paper’s acceptance. The Register asked Visa for comment and received no response. The countermeasures the paper proposes sit at the kernel, terminal, and issuer layers: bind the expiry date cryptographically to an issuer-verifiable signature, require terminals to compare both expiry representations and make mismatches visible to the issuer, and have issuers authorize against the PAN-and-expiry combination rather than the PAN alone. For cardholders, the researchers recommend destroying the chip and magnetic stripe of expired cards rather than discarding them intact. Given that the attack requires only the expired physical card or sustained NFC proximity to it, that guidance is now slightly less hypothetical than it was before this paper.

A previously unknown malware family dubbed SynkLoader is being distributed in Microsoft Teams phishing campaigns to steal credentials via a fake lock screen. The attacker impersonates the target company's IT help desk, a tactic Microsoft highlighted earlier this year as increasingly common in multi-stage attacks. Expel’s security researcher Marcus Hutchins explains that the attacks direct the victim to install a fake “PowerShell Cleaner” executable (.MSI) hosted in Microsoft Azure, making the download appear trustworthy. Analysis of the malware showed "compile dates and file timestamps indicating it was first compiled and distributed around July 28, 2026." The installer extracts a PowerShell script named cleaner.ps1 and a ZIP archive containing the Python framework, a malicious Python script, precompiled Python libraries, and several fake Microsoft runtime DLLs.
Microsoft says ongoing issues causing games to crash or fail to launch after installing the August 2026 Windows updates may be caused by peripherals with RGB lighting. As Microsoft explained when it confirmed it's investigating on Wednesday, this known issue affects games like ARC Raiders, MARVEL Tōkon: Fighting Souls, and The Finals on systems running Windows 11 24H2 and 25H2. "Following the release of Windows updates on August 11, 2026 (KB5121003) and later, Microsoft received reports of issues involving inability to run games as expected," Microsoft said on the Windows release health dashboard. On impacted PCs, users are also experiencing gaming freezes, "EXCEPTION_ACCESS_VIOLATION" errors, and even unexpected system restarts. In a Thursday update, Microsoft said the gaming issues may be caused by drivers or components installed by RGB devices on affected Windows systems.
