Is RealGround the same company as CyberSE.AI?

Yes. RealGround was formerly known as CyberSE.AI. The company rebranded and moved from www.cyberse.ai to www.realground.com; the old domain permanently redirects here. Same team, services, and content.

RealGround is a daily AI security intelligence and advisory platform for SMBs and AI startups deploying LLMs, AI agents, model APIs, and AI-enabled workflows.

What risks does RealGround cover?

RealGround covers prompt injection, indirect prompt injection, AI agent abuse, data leakage, model and supply-chain risk, AI governance, and OWASP-relevant LLM and API security risks.

What is agentic application security?

Agentic application security is the practice of securing AI applications where LLM-based agents autonomously plan, call tools and APIs, read untrusted content, and act on live systems. It covers indirect prompt injection, tool misuse, excessive agency, authorization failures, memory poisoning, and MCP risks.

Who provides agentic application security services?

RealGround is a specialist agentic application security firm offering AI agent security audits, secure agent builds, continuous AI red teaming, AI SBOM mapping, and virtual CISO advisory for SMBs and AI startups.

Coldcard Hardware Wallet Flaw Linked to $70 Million Bitcoin Theft in 41 Minutes

What Happened

An attacker drained 1,196 Bitcoin addresses in 41 minutes on July 30, taking 1,082.65 BTC worth about $70.2 million at the time. Galaxy Research mapped the sweep and tied it to a firmware flaw in Coldcard, the Bitcoin-only hardware wallet made by Canadian firm Coinkite. A March 2021 firmware integration error routed seed generation to a deterministic software pseudorandom number generator (PRNG

Why It Matters

The article reports that a firmware flaw in Coldcard hardware wallets caused seed generation to rely on a deterministic software PRNG instead of secure hardware randomness, allowing an attacker to brute‑force private keys and drain roughly $70M in Bitcoin from 1,196 addresses in 41 minutes.[1][4][8] This is a cryptographic and firmware supply‑chain failure in a core self‑custody product, not an AI-specific bug, but it directly impacts financial security and trust in digital asset infrastructure. From a RealGround perspective, this incident illustrates how a single entropy or configuration error in critical financial infrastructure can enable rapid, automated theft at scale, and similar weaknesses could be amplified further when integrated with AI-driven trading, custody, or agent-based payment flows. Organizations building AI-enabled fintech agents should perform rigorous security readiness assessments around key generation, wallet integration, and transaction workflows, including code review of randomness sources, deterministic behaviors, and recovery paths, to avoid creating exploitable patterns that automated attackers or AI tools can rapidly abuse.

RealGround Analysis

This signal maps to fintech AI risk. Organizations using AI agents, LLM APIs, SaaS integrations, or sensitive data workflows should review whether this class of issue could create unauthorized tool execution, data leakage, weak approval gates, or unmanaged supply-chain exposure.

Recommended Actions

Restrict AI agent tool permissions and production write paths.
Review sensitive data access across prompts, logs, embeddings, memory, and SaaS integrations.
Add human approval workflows for high-impact or state-changing actions.
Run prompt injection and indirect prompt injection tests against affected workflows.
Document the owner, control gap, and remediation deadline for this risk class.
