Inside the attack chain: Azure Blob Storage threats

🔐 Microsoft Threat Intelligence analyzes how attackers target Azure Blob Storage across the full attack chain, emphasizing risks from exposed containers, compromised keys and SAS tokens, and abuse of automation such as Event Grid and Azure Functions. The blog maps these behaviors to the MITRE ATT&CK framework and illustrates tactics including data poisoning, covert C2 via metadata, and replication-based distribution. Microsoft recommends applying zero trust principles, enforcing least privilege with Microsoft Entra RBAC/ABAC, and enabling Defender for Storage with malware scanning, CSPM, and sensitive data discovery to detect, contain, and remediate storage-focused threats.

Significant Satellite Traffic Found Transmitted Unencrypted

⚠️Researchers used a commercial off-the-shelf satellite dish to perform the most comprehensive public study yet of geostationary satellite communications. They discovered a shockingly large volume of sensitive traffic—critical infrastructure telemetry, internal corporate and government communications, private voice calls and SMS, and consumer Internet streams such as in-flight Wi‑Fi—being broadcast unencrypted. Much of this data can be passively observed by anyone with a few hundred dollars of consumer-grade hardware, and a single transponder's footprint may cover up to 40% of the Earth's surface.

CometJacking: One-Click Attack Turns AI Browser Rogue

🔐 CometJacking is a prompt-injection technique that can turn Perplexity's Comet AI browser into a data exfiltration tool with a single click. Researchers at LayerX showed how a crafted URL using the 'collection' parameter forces the agent to consult its memory, extract data from connected services such as Gmail and Calendar, obfuscate it with Base64, and forward it to an attacker-controlled endpoint.
