Google released an open-source zero-trust reference architecture for AI agents defending against prompt injection via signed database writes, gVisor sandboxing, and deterministic gating.
Google's demonstration, built on the Agent Development Kit (ADK) and Gemini, shows a customer support agent that could be manipulated into issuing a $10,000 refund on a $149 order and exposing environment variables via AI-generated Python. The architecture adds three security layers outside the model: cryptographic signatures on database writes verified via Cloud KMS backed by Cloud HSM, gVisor sandboxing of generated code with network egress disabled, and a Semantic Gateway applying deterministic checks to prompts and tool calls. It treats system prompts as insufficient boundaries because prompt injection, prompt tuning, or model updates can change agent behavior.
BlackFile (UNC6671), a The Com-linked extortion crew, keeps hitting financial and med tech firms with voice-phishing IT-support scams and ~$3 million demands.
Google Threat Intelligence Group (tracking BlackFile as UNC6671, linked to The Com) reports the extortion group remains active, shifting focus to the financial sector and med tech organizations, with new Redact-brand extortion demands issued last week. The group impersonates IT support in voice-phishing attacks using hundreds of recruited callers, targets large firms in what researchers call big-game hunting, and processes an average of 1.5 new victims daily. Extortion demands start around $3 million and are typically negotiated below $1 million; Flashpoint observed infrastructure targeting Blackstone, Bain Capital, Moody's, CME, and Apollo, though compromise is unconfirmed. Mandiant has responded to more than two dozen BlackFile compromises since January, and victims face escalation tactics including swatting.
Unit 42 unveils agent session smuggling, where a rogue AI agent hides covert instructions in established Agent2Agent (A2A) protocol sessions to manipulate victim agents.
Palo Alto Networks Unit 42 discovered agent session smuggling, a new attack technique in which a malicious AI agent exploits an established cross-agent session under the Agent2Agent (A2A) protocol to send covert instructions hidden among benign client requests and server responses. The technique leverages the implicit trust agents place in collaborating agents and the stateful, multi-turn nature of A2A sessions; the researchers stress it affects any stateful protocol, not an A2A flaw. Unlike one-shot data-based attacks, a rogue agent can converse, adapt and build false trust over multiple interactions. Proposed mitigations include human-in-the-loop enforcement, cryptographically signed AgentCards for remote agent verification, and context-grounding to detect injected instructions.
Brazilian malspam campaigns continue evolving, abusing Google URL shortener and Dropbox and using Squiblydoo plus DLL side-loading to deploy likely infostealing botnet malware.
A June 2017 Brazilian malspam campaign spoofed IPTU tax notification emails, using the recipient's address as the sender, and abused Google's URL shortener and Dropbox to deliver a zip containing a malicious Windows shortcut (.lnk) file. The LNK used the Squiblydoo technique (regsvr32.exe) to download and execute a scriptlet with elevated privileges, retrieving a signed G-Buster Browser Defense executable alongside a malicious fltLib.dll loaded via side-loading, likely an information-stealing botnet. Post-infection HTTP traffic exposed over 400 infected Windows hosts, mostly in Brazil, with 2,132 Banload-tagged samples observed in the first half of 2017.
Group-IB discovered WindRelay Android malware that streams NFC card data in real time, paired with SpyNote RAT, targeting Czechia, Slovakia, and Slovenia.
Group-IB identified WindRelay, an Android malware that uses NFC to communicate with victims' payment cards and relays the exchange live to attacker-controlled terminals. Fraudsters impersonate bank staff by phone, trick victims into installing a personalized SpyNote RAT, then silently deploy WindRelay to cash out using the victim-entered PIN. Researchers traced 23 samples on VirusTotal from November 2025 to July 2026, four C2 IPs, and campaigns against Czechia, Slovakia, and Slovenia. No affected apps were found on Google Play, and Google Play Protect detects known versions.

Google's Threat Intelligence Group reports data theft extortion is surging, with Silent Ransom extracting $10M and $18M from two law firms and BlackFile taking $10M.
Risky Business News, citing Google Threat Intelligence Group (GTIG), reports that cybercriminals are shifting from encrypting ransomware to data theft extortion. Law firms Goodwin Procter and WilmerHale paid Silent Ransom (Luna Moth) ransoms of $10 million and $18 million respectively; GTIG says the group often completes contact-to-extortion in a single day, now sometimes compromising systems in person posing as IT staff. BlackFile, now calling itself Redact, used high-volume vishing to steal credentials and pivot through OneDrive, SharePoint and other SaaS apps, collecting more than $10 million between February and mid-May with an average ransom of $750,000, including attempted attacks on Wall Street hedge funds and private equity firms. The piece argues governments should keep pressure on encrypting ransomware gangs while lower-impact extortion absorbs criminal energy.

Researchers found 737 Chrome VPN extensions, many impersonating brands like NordVPN, routing roughly 75,000 users' browser traffic through attacker-controlled SOCKS5 proxies.
Socket and researcher Kush Pandya identified 737 Chrome VPN and proxy extensions, published across at least 40 developer accounts with 75,486 installs, that route entire browser sessions through one provider's SOCKS5 proxies on port 1082. Of these, 274 impersonate 66 established brands including Proton VPN, NordVPN, Surfshark, ExpressVPN, and Cloudflare 1.1.1.1. The proxy bypass list only excludes loopback addresses, exposing visited destinations, source IPs, TLS SNI values, and plain-HTTP request bodies to the operator. 221 extensions have been removed from the Chrome Web Store while 516 remain listed as active.
Researchers show encrypted reasoning blocks in OpenAI, Anthropic, and Google APIs can be replayed to recover hidden reasoning and secrets like API keys.
Researchers demonstrated that encrypted reasoning objects from OpenAI, Anthropic, and Google reasoning APIs could be replayed across sessions, users, and models, letting weaker same-family models act as decoders of hidden reasoning. Across 6,708 public agent trajectories they decoded 315,320 thinking blocks and found 704 privacy artifacts from real user sessions, including 62 API keys, 33 passwords, 24 access tokens, and seven private keys. The replayable blocks also enabled invisible prompt-injection proof-of-concepts; the main extraction attack is no longer reproducible as of August 2026 following mitigations, though no vendor has publicly acknowledged the flaw.

Chrome adopts device-bound session credentials that tie login sessions to a specific device, defending against cookie-theft account takeover attacks.
Chrome is adopting device-bound session credentials, which bind authenticated sessions to the physical device rather than to transferable cookies. The mechanism targets a common account takeover technique in which attackers steal session cookies and replay them on other machines. Ars Technica characterizes it as possibly the strongest protection yet against this class of takeover, which has become increasingly common.
Unit 42 details three attack paths letting Windows malware silently sign into passkey-protected accounts via Chrome's Google Password Manager without user verification.
Palo Alto Networks Unit 42 described three post-compromise attack paths—Pass-ta-key, Silver Pass-ta-key and Golden Pass-ta-key—against Chrome's Google Password Manager cloud authenticator on TPM-equipped Windows systems. The attacks can silently obtain valid authentication assertions, install attacker-controlled user-verification keys, or extract the 32-byte Security Domain Secret used to decrypt synced passkey private keys, enabling reusable access from the attacker's own environment. No CVE was assigned and no exploitation in the wild was reported; demonstrations were validated against Chrome 142 and parts of the architecture are corroborated by Chromium source. GitHub enforced the User Verified flag check, while eBay accepted a test assertion lacking it before fixing its validation gap after disclosure.

The model found CVE-2026-15903 (CVSS 8.8), an out-of-bounds read/write in Chrome's V8 JavaScript engine that Google patched in mid-July 2026. It is available to trusted partners including CrowdStrike, Palo Alto Networks and Cloudflare through the Daybreak Red access tier.
Three research teams showed passkey bypasses: WebAuthn assertion replay in Microsoft Entra ID, synced-passkey key recovery in Google Password Manager, and Windows Hello key reuse.
SpecterOps' Pass-the-Passkey research showed Windows stored past YubiKey signatures in cleartext and chained this with Microsoft Entra ID passkey validation weaknesses to impersonate privileged users despite phishing-resistant MFA; the Windows Event Logging Service issue is tracked as CVE-2026-34348 (CVSS 6.5) and fixed in July 2026 updates. Unit 42's Golden Pass-ta-key attack recovered the 32-byte Security Domain Secret protecting Google Password Manager synced passkeys from Chrome on Windows via pre-existing malware. Dirk-jan Mollema showed in-session malware can use a hardware-bound Windows Hello for Business key without a fresh PIN or biometric check. Microsoft applied Entra-side mitigations for the relay assertion issue; no real-world exploitation has been reported.
Researchers showed malicious SIM cards can issue RUN AT commands to execute code on Qualcomm modems, compromising Quectel-based cellular IoT devices like EV chargers.
Researchers at the University of Birmingham and Fuzzware found 9 of 26 tested devices accept SIM proactive commands, including six Qualcomm-based cellular modules, five of them Quectel. They achieved code execution on a commercial Autel EV charger via the Quectel EC25's atfwd_daemon unsafe format string, and demonstrated an irreversible 2G downgrade, modem power-off, and arbitrary file reads via a root TFTP daemon on a Quectel EG25-G. Attacks require a hostile SIM already in the slot or an interposer; no attacks have been reported in the wild. Qualcomm has built a hardened configuration disabling the interface by default and Quectel mitigated the file-access flaw; the paper was presented at USENIX WOOT.
Actively Exploited V8 Type Confusion in Google Chrome (CVE-2026-85046)
Google Chrome versions prior to 152.0.7977.82 contain a type confusion flaw (CWE-843) in the V8 JavaScript engine, which mishandles object types during engine operations (public proof-of-concept writeups indicate it is reachable through array sorting and WebAssembly-related code paths). A remote attacker triggers the flaw simply by getting a user to open a crafted HTML page, with no privileges or authentication required. Successful exploitation lets the attacker execute arbitrary code inside the browser's sandbox, and public reporting shows it being chained with Windows zero-days (the 'BlueMoon' exploit kit) by Chinese espionage groups for broader compromise. Any user of an unpatched Chrome or another build embedding the affected V8 engine is exposed. The vulnerability is a zero-day that was actively exploited in the wild before patching, was added to CISA's KEV on 2026-09-04, and has five public proof-of-concept references.

Actively Exploited Out-of-Bounds Write in Google Chrome V8
CVE-2026-87491 is an out-of-bounds write (CWE-787) in the V8 JavaScript engine in Google Chrome, fixed in Chrome 153.0.8010.36, which Google shipped alongside roughly 230 other security fixes. An attacker can trigger the flaw remotely by luring a user (user interaction required) into opening a crafted HTML page that corrupts memory in V8. Successful exploitation allows the attacker to execute arbitrary code inside the Chrome browser sandbox, which constrains but does not eliminate the impact. All Google Chrome users running versions prior to 153.0.8010.36 are affected; because the flaw resides in V8, CISA tracks it as 'Google Chromium V8', and other Chromium-based browsers may inherit the fix in their own updates. The flaw is being actively exploited in the wild — it is the seventh actively exploited Chrome zero-day of 2026 and was added to CISA's KEV catalog on 2026-09-09 — though no public proof-of-concept is known and ransomware use is unknown.

Heap-Based Buffer Overflow in Windows ALPC Enables Local Privilege Escalation
CVE-2026-85880 is a heap-based buffer overflow in Windows Advanced Local Procedure Call (ALPC), the Windows mechanism for local inter-process communication. An authorized local attacker can trigger the overflow by submitting crafted input over ALPC, corrupting heap memory in the component that handles the request. Successful exploitation allows the attacker to execute code with elevated privileges, typically gaining SYSTEM-level control of the local host, which is especially valuable as a post-exploitation or sandbox-escape step. Affected products include Windows 10 (1607, 1809, 21H2, 22H2) and Windows Server 2012, 2016, 2019, and 2022, meaning most on-premises Windows estates are in scope. The flaw was fixed in Microsoft's record 974-CVE September 2026 Patch Tuesday and was added to CISA's KEV on 2026-09-08, confirming exploitation in the wild; press reports describe Windows zero-days being chained with a Chrome zero-day in 'BlueMoon' kit attacks, though the data does not explicitly confirm this CVE is the Windows flaw in that chain.

Out-of-Bounds Write in Google Chrome's Skia Rendering Engine
CVE-2026-3909 is an out-of-bounds write (CWE-787) in the Skia graphics rendering library used by Google Chrome, which Google patched in Chrome 146.0.7680.75. A remote attacker can trigger the flaw by luring a user to visit a crafted HTML page, causing out-of-bounds memory access in the browser process; the High CVSS 8.8 score with high confidentiality, integrity, and availability impact indicates memory corruption with potentially serious consequences. All Google Chrome installations running versions prior to 146.0.7680.75 are affected, and because the vulnerability resides in the Skia engine, the vulnerable code is present in every Chrome install. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-03-13, indicating exploitation in the wild, though no public proof-of-concept is known and ransomware use is unknown. EPSS currently assigns a 1.6% probability of exploitation within the next 30 days (75th percentile).

Use-After-Free in Google Chrome's Dawn (WebGPU) Component Enables Arbitrary Code Execution
CVE-2026-5281 is a use-after-free vulnerability in Dawn, the WebGPU implementation in Google Chrome, that Google patched in Chrome 146.0.7680.178. It is triggered when a remote attacker serves a crafted HTML page and can leverage it after having already compromised the Chrome renderer process, escalating to arbitrary code execution beyond the initial foothold. Because the flaw requires a compromised renderer as a starting point, it is typically chained with another bug (such as a renderer-exploiting issue) to break out to arbitrary code execution with real impact on confidentiality, integrity, and availability. Any user or organization running Google Chrome on a version prior to 146.0.7680.178 is affected. The flaw is confirmed as exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-04-01, and its EPSS score of 4.9% (92nd percentile) indicates a meaningful near-term exploitation probability.

Out-of-Bounds Read/Write in Google Chrome V8 Enables In-Sandbox Code Execution
CVE-2026-11645 is an out-of-bounds read and write (CWE-125/CWE-787) in V8, the JavaScript engine used by Google Chrome and Chromium. A remote attacker triggers the flaw by luring a user to a crafted HTML page, where malicious script causes V8 to read and write outside allocated memory buffers. Successful exploitation allows the attacker to execute arbitrary code inside the browser's security sandbox, providing limited privileges within that process rather than full system compromise. All Google Chrome versions prior to 149.0.7827.103 are affected, along with the Chromium V8 component identified by CISA. The flaw is being exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-06-09, and related headlines describe an actively exploited Chrome V8 zero-day, though no public proof-of-concept is known and ransomware use is unconfirmed.

Out-of-Bounds Memory Flaw in Google Chrome V8 Allows Sandboxed Code Execution
CVE-2026-3910 is an out-of-bounds memory flaw — CISA classifies it as improper restriction of operations within the bounds of a memory buffer — caused by an inappropriate implementation in the V8 JavaScript and WebAssembly engine used in Google Chrome. A remote attacker triggers it by luring a user to a crafted HTML page, so exploitation requires user interaction but no privileges or special conditions. Successful exploitation allows the attacker to execute arbitrary code inside the Chrome sandbox, which confines the compromise to the renderer process rather than the full system, but still exposes data and credentials handled within the browser session. Anyone running Google Chrome prior to 146.0.7680.75 — or a Chromium-based browser that embeds the vulnerable V8 code — is affected. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-03-13, and it comes amid a string of actively exploited Chrome V8 zero-days that Google has fixed during 2026.

Use-After-Free in Google Chromium CSS Rendering Exposes Chrome, Edge, Opera Users
CVE-2026-2441 is a use-after-free (CWE-416) in Google Chromium's CSS handling that a remote attacker can trigger by getting a user's browser to process a crafted HTML page, potentially corrupting the heap. Successful exploitation yields a memory-corruption primitive in the browser; CVSS scoring is not yet available, but Chromium memory-safety flaws of this class can range from crashes to potential code execution depending on how the corruption is leveraged. Anyone running Chromium or a Chromium-based browser — Google Chrome, Microsoft Edge, Opera, and numerous embedded/branded browsers — is potentially affected, making the exposed population effectively all modern browser users. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-02-17, confirming it is being exploited in the wild; EPSS assigns a 22% probability of exploitation within 30 days (98th percentile), no public PoC is known, and any ransomware association is unknown.

Permission Bypass in Google Pixel Cellular Modem Allows Proximal Privilege Escalation
A logic error in the cellular modem component causes an improper authorization check (CWE-285/CWE-693), allowing a permission bypass. An attacker who already has low privileges and is on an adjacent network (proximal, e.g., a hostile local or cellular-adjacent network) can trigger the flaw without any user interaction, and successful exploitation yields remote escalation of privilege with high impact on confidentiality, integrity, and availability (CVSS 3.1 base score 8.0). The flaw was assigned through Google's device security CNA ([email protected]), consistent with modem firmware shipped in Google Pixel-class devices; specific affected firmware versions were not provided in the source data. No public proof-of-concept is known, the issue is not listed in CISA's KEV catalog, and there is no evidence of exploitation in the wild. Defenders should treat this as a patch-on-next-bulletin item unless devices operate in high-risk adjacent-network environments.

Use-After-Free in WebGL in Google Chrome Allows Code Execution Outside the Sandbox
CVE-2026-87464 is a use-after-free (CWE-416) in the WebGL component of Google Chrome affecting versions prior to 153.0.8010.36. A remote attacker can trigger it by luring a user to open a crafted HTML page, which corrupts memory in the browser's WebGL rendering path. Successful exploitation allows arbitrary code execution outside the browser sandbox, meaning the attacker escapes Chrome's process isolation and runs code with the privileges of the browser on the host. All Chrome users running an unpatched version before 153.0.8010.36 are affected. As of now there is no public proof-of-concept and this specific flaw is not in CISA KEV, although the Chrome 153 release headlines reference a separate V8 zero-day that was exploited in the wild.
