👿 𝐇𝐢𝐣𝐚𝐜𝐤𝐢𝐧𝐠 𝐀𝐦𝐚𝐳𝐨𝐧 𝐄𝐯𝐞𝐧𝐭𝐁𝐫𝐢𝐝𝐠𝐞 𝐟𝐨𝐫 𝐥𝐚𝐮𝐧𝐜𝐡𝐢𝐧𝐠 𝐂𝐫𝐨𝐬𝐬-𝐀𝐜𝐜𝐨𝐮𝐧𝐭 𝐚𝐭𝐭𝐚𝐜𝐤𝐬 Square's Ramesh Ramani describes six attack patterns leveraging EventBridge's cross-account capabilities for infiltration and exfiltration. AWS EventBridge is a serverless event bus service that enables powerful integrations across multiple AWS accounts. The attacks: 1. Persistent beaconing 2. Command and control 3. Reconnaissance 4. Data smuggling 5. Account hopping 6. API borrowing The post provides code examples for each attack and recommends multi-layered security controls, including Service Control Policies, IAM permissions, EventBridge resource policies, VPC endpoints with restrictive policies, and event content validation, along with detection strategies using CloudWatch, CloudTrail, and behavioral analytics. developer.squareup.com/blog/hijacking… #cybersecurity

@Caltrain this is the second day in a row that train 221 is delayed due to "mechanical issues" . Yesterday by 24 minutes and today by 15 minutes. Why are there constants issues/delays?
