Attack Surface Management | Criminal IP ASMCriminal IP’s Attack Surface Management (ASM) is a threat-intelligence–driven platform that continuously discovers, inventories, and monitors every internet-connected asset associated with an organization, including shadow and forgotten resources, so teams see their true external footprint from an attacker’s perspective. The solution combines automated asset discovery with OSINT techniques, AI enrichment and advanced threat intelligence to surface exposed hosts, domains, cloud services, IoT endpoints and other Internet-facing vectors, capture evidence (screenshots and metadata), and correlate findings to known exploitability and attacker tradecraft. ASM prioritizes exposures by business context and risk, highlights vulnerable components and misconfigurations, and provides real-time alerts and dashboards to speed investigation and remediation.

Haze
Background blurring for Compose Multiplatform
Haze is a modern UI library designed for Jetpack Compose and Compose Multiplatform that enables advanced background blurring effects commonly associated with glassmorphism design. It provides a high-level abstraction for creating dynamic blur effects that apply to content behind UI elements rather than just the elements themselves, solving a limitation of standard blur modifiers. The library is built on top of Compose’s graphics layer APIs, allowing it to operate consistently across multiple platforms while maintaining performance. It introduces a flexible styling system where developers can define blur intensity, masking, and opacity dynamically using composable scopes. One of its standout features is support for progressive blurring, where blur intensity changes across a gradient, creating more visually refined effects. It also includes prebuilt “material” styles inspired by platforms like iOS and Windows, enabling developers to replicate native design aesthetics. -
