- Flaws in Bluetooth Headphones Utilizing Airoha Chips Detailed — Extra particulars have emerged about three vulnerabilities impacting Bluetooth headphones utilizing Airoha chips: CVE-2025-20700, CVE-2025-20701, and CVE-2025-20702. The issues impacted headphones from Sony, Marshall, JBL, and Beyerdynamic, and had been patched again in June. The problems may very well be exploited by an attacker in bodily proximity to silently connect with a pair of headphones by way of BLE or Traditional Bluetooth, exfiltrate the flash reminiscence of the headphones, and extract the Bluetooth Hyperlink Key. This, in flip, permits the attacker to impersonate a “Bluetooth” gadget, connect with a goal’s telephone, and work together with it from the privileged place of a trusted peripheral, together with even eavesdropping on conversations and extracting name historical past and saved contacts.
- Ransomware Turns Breaches into Bidding Wars — Ransomware’s evolution from digital extortion right into a “structured, profit-driven felony enterprise” has paved the best way for an ecosystem that not solely makes an attempt to ransom stolen information, but additionally monetizes for max revenue by promoting it to the best bidder by information auctions. “By opening extra revenue streams and attracting extra individuals, these actors are amplifying each the frequency and influence of ransomware operations,” Rapid7 mentioned. “The rise of information auctions displays a maturing underground financial system, one which mirrors legit market habits, but drives the continued growth and professionalization of worldwide ransomware exercise.”

As a result of these messages come from the official Microsoft Groups sender tackle (no-reply@groups.mail[.]microsoft), they could bypass person suspicion and e-mail filters,” Trustwave mentioned.
- Groups Vishing Attack Results in .NET Malware — In one other marketing campaign noticed by the security vendor, a vishing marketing campaign originating from Groups has been discovered to trick unsuspecting customers into putting in Fast Help software program, in the end resulting in the deployment of a multi-stage .NET malware utilizing an executable named updater.exe. “The Sufferer receives a Groups name from an attacker impersonating Senior IT Workers,” it mentioned. “Attacker convinces person to launch Fast Help. The ‘updater.exe’ is a .NET Core 8.0 wrapper with embedded “loader.dll” that downloads encryption keys from jysync[.]information, retrieves encrypted payload, decrypts utilizing AES-CBC + XOR, then masses meeting straight into reminiscence for fileless execution by way of reflection.”
- search engine marketing Poisoning Distributes Oyster — A search engine marketing (search engine marketing) poisoning marketing campaign has continued to advertise pretend websites when customers seek for Microsoft Groups or Google Meet to distribute a backdoor referred to as Oyster. This malware distribution risk has been energetic since a minimum of November 2024. In July 2025, Arctic Wolf mentioned it noticed an analogous wave of assaults that leveraged bogus websites internet hosting trojanized variations of legit instruments like PuTTY and WinSCP to ship the malware. Oyster is delivered by way of a loader element that is liable for dropping the principle element. The principle payload then gathers system info, communicates with a C2 server, and gives the power to remotely execute code.
- Faux SAP Concur Extensions Ship FireClient Malware — A brand new marketing campaign found by BlueVoyant is deceiving customers into downloading pretend SAP Concur browser extensions. The pretend browser extension installer comprises a loader designed to assemble host info and ship it to its C2 server. The loader subsequently extracts an embedded backdoor referred to as FireClient that comprises performance to execute distant instructions utilizing the command console and PowerShell.

The place to begin is an MSI installer that deploys a conveyable model of Firefox to the listing “LOCALAPPDATAProgramsFirefox” in a deliberate effort to evade detection and keep away from conflicts with current Firefox installations. “After set up, the MSI file launches Firefox in headless mode, which means the browser runs and not using a seen window, making its execution undetectable to the person,” researchers Joshua Inexperienced and Thomas Elkins mentioned. “As soon as Firefox is working, the person’s default browser is opened and redirected to the legit Concur web site. This tactic is meant to create the phantasm that the extension set up was profitable, thereby deceiving the person.” Within the background, the malware proceeds to overwrite configuration recordsdata positioned inside Firefox profile directories to induce the browser to launch the loader DLL. BlueVoyant’s evaluation has uncovered tactical and infrastructural overlaps with GrayAlpha (aka FIN7), which was beforehand noticed leveraging pretend browser replace web sites as a part of its operations. “The FireClient malware doubtless represents a complicated element of GrayAlpha’s evolving toolkit, deployed inside a multi-pronged marketing campaign leveraging quite a lot of trusted software program lures,” the corporate mentioned.
- OpenAI Says Immediate Injections Could By no means Go Away in Browser Brokers — OpenAI disclosed that it shipped a security replace to its ChatGPT Atlas browser with a newly adversarially educated mannequin and strengthened surrounding safeguards to higher fight immediate injections, which makes it attainable to hide malicious directions inside on-line content material and trigger the synthetic intelligence (AI) agent to override its guardrails. The corporate conceded that “agent mode” in ChatGPT Atlas broadens the security risk floor. “This replace was prompted by a brand new class of prompt-injection assaults uncovered by our inside automated pink teaming,” it mentioned. The AI firm mentioned it constructed an LLM-based automated attacker and educated it with reinforcement studying to search for immediate injections that may efficiently assault a browser agent. “Immediate injection, very like scams and social engineering on the internet, is unlikely to ever be absolutely ‘solved,'” it added. “However we’re optimistic {that a} proactive, extremely responsive fast response loop can proceed to materially scale back real-world danger over time. By combining automated assault discovery with adversarial coaching and system-level safeguards, we will establish new assault patterns earlier, shut gaps sooner, and constantly elevate the price of exploitation.” The modifications are consistent with related approaches undertaken by Anthropic and Google to battle the persistent danger of prompt-based assaults. The event comes as Microsoft revealed that adversaries have begun implementing AI throughout a spread of malicious actions, together with automated vulnerability discovery or phishing campaigns, malware or deepfake era, information evaluation, affect operations, and crafting convincing fraudulent messages. “AI-automated phishing emails achieved 54% click-through charges in comparison with 12% for traditional makes an attempt – a 4.5x enhance,” it mentioned. “AI permits extra focused phishing and higher phishing lures.”
