Multiple HTTP/2 implementations have been found susceptible to a new attack technique called MadeYouReset that could be explored to conduct powerful denial-of-service (DoS) attacks. "MadeYouReset bypasses the typical server-imposed limit of 100 concurrent HTTP/2 requests per TCP connection from a client. This limit is intended to mitigate DoS attacks by restricting the number of simultaneous requests a client can send," researchers Gal Bar Nahum, Anat Bremler-Barr, and Yaniv Harel said . "With MadeYouReset, an attacker can send many thousands of requests, creating a denial-of-service condition for legitimate users and, in some vendor implementations, escalating into out-of-memory crashes." The vulnerability has been assigned the generic CVE identifier, CVE-2025-8671 (CVSS score: 7.5), although the issue impacts several products, including Apache Tomcat ( CVE-2025-48989 ), F5 BIG-IP ( CVE-2025-54500 ), and Netty ( CVE-2025-55163 ). MadeYouReset is the latest fl...

Japan's CERT coordination center (JPCERT/CC) on Thursday revealed it observed incidents that involved the use of a command-and-control (C2) framework called CrossC2 , which is designed to extend the functionality of Cobalt Strike to other platforms like Linux and Apple macOS for cross-platform system control. The agency said the activity was detected between September and December 2024, targeting multiple countries, including Japan, based on an analysis of VirusTotal artifacts. "The attacker employed CrossC2 as well as other tools such as PsExec, Plink, and Cobalt Strike in attempts to penetrate AD. Further investigation revealed that the attacker used custom malware as a loader for Cobalt Strike," JPCERT/CC researcher Yuma Masubuchi said in a report published today. The bespoke Cobalt Strike Beacon loader has been codenamed ReadNimeLoader. CrossC2, an unofficial Beacon and builder, is capable of executing various Cobalt Strike commands after establishing communicati...

You check that the windows are shut before leaving home. Return to the kitchen to verify that the oven and stove were definitely turned off. Maybe even circle back again to confirm the front door was properly closed. These automatic safety checks give you peace of mind because you know the unlikely but potentially dangerous consequences of forgetting – a break-in, fire, or worse. Your external-facing IT infrastructure deserves the same methodical attention. External Attack Surface Management (EASM) and Digital Risk Protection (DRP) tools provide that same peace of mind for your digital "home," automating the everyday safety checks that prevent costly incidents. Why does the external-facing IT infrastructure need the same care? Just as you secure your physical home prior to leaving, your assets that are exposed to the internet require consistent safety protocols. Think about it this way:  Locking doors = locking down exposed assets, ensuring only authorized access points...

Cybersecurity researchers have disclosed a new Android trojan called PhantomCard that abuses near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil. "PhantomCard relays NFC data from a victim's banking card to the fraudster's device," ThreatFabric said in a report. "PhantomCard is based on Chinese-originating NFC relay malware-as-a-service." The Android malware, distributed via fake Google Play web pages mimicking apps for card protection, goes by the name "Proteção Cartões" (package name "com.nfupay.s145" or "com.rc888.baxi.English"). The bogus pages also feature deceptive positive reviews to persuade victims into installing the app. It's currently not known how links to these pages are distributed, but it likely involves smishing or a similar social engineering technique. Once the app is installed and opened, it requests victim...

Google said it's implementing a new policy requiring developers of cryptocurrency exchanges and wallets to obtain government licenses before publishing apps in 15 jurisdictions in order to "ensure a safe and compliant ecosystem for users." The policy applies to markets like Bahrain, Canada, Hong Kong, Indonesia, Israel, Japan, the Philippines, South Africa, South Korea, Switzerland, Thailand, the United Arab Emirates, the United Kingdom, the United States, and the European Union. The changes do not apply to non-custodial wallets. This means developers publishing cryptocurrency exchange and wallet apps have to hold appropriate licences or be registered with relevant authorities like the Financial Conduct Authority (FCA) or Financial Crimes Enforcement Network (FinCEN), or authorized as a crypto-asset service provider (CASP) under the Markets in Crypto-Assets (MiCA) regulation before distribution. "If your targeted location is not on the list, you may continue to p...
