NCSC – CERT-SE veckobrev v.46

Swedish cybersecurity agencies issue weekly brief highlighting recent cyberattacks and phishing campaigns.

The NCSC-CERT-SE weekly brief from Sweden highlights recent cyberattacks, including extensive disruptions to Microsoft services affecting users in 74 countries. It also details intrusions at furniture company Kinnarps, a data breach at Maersk involving the WhiteArmor ransomware, and exposed booking data from IT provider Amadeus impacting airlines like SAS. Additionally, Sega reported a breach at a third-party vendor exposing customer email addresses, and a threat actor exploited compromised IAM credentials to access multiple customer AWS environments via the Qubole data platform.

The lesson from this incident

Full lesson

This weekly brief illustrates how a single weak link in the supply chain — whether a third-party vendor like Sega's unnamed partner, the Amadeus IT provider, or the Qubole data platform — can cascade into widespread customer data exposure. In the AWS case, a threat actor exploited compromised IAM credentials to pivot laterally across multiple customer environments, demonstrating how poor credential hygiene in a shared platform magnifies blast radius. Organizations are often unaware of the security posture of their technology partners until a breach occurs. This matters because customer trust, regulatory obligations, and operational continuity all depend on the security controls of vendors that organizations may have little direct visibility into.
