Welcome to This Week in Cloud, a weekly digest of the most important cloud and cybersecurity stories. In this installment, we examine the aftermath of the Yahoo data breach and new disclosures from the international bank transaction system, SWIFT.
Yahoo’s Historic Hack
Yahoo’s breach of 500 million customer accounts set the record for the biggest data breach ever in terms of accounts exposed. While many on social media mocked the triviality of stealing login information for Yahoo’s mail service, Yahoo’s portfolio services represent three of the top 20 consumer cloud services used in the workplace. The breach illustrates the cybersecurity factor of mergers and acquisitions, as the acquirer prepares to integrate systems and take inventory of sensitive information. Verizon certainly has their work cut out for them.

Global Banking Network Gets Desperate
Potential vulnerabilities in the configuration of a global banking technology from SWIFT first came to light when the Bangladesh central bank fell victim to cybertheft. SWIFT provides the technology that authorizes transactions at major banks. At the time of the Bangladesh hack, SWIFT released cybersecurity best practices to customers. Now, SWIFT revealed three additional banks were targeted and has come out with mandatory security guidelines for customers. While banks do not take cybersecurity lightly, the new compliance framework acknowledges SWIFT has become a target for cybercriminals and forces banks to take action.

OpenSSL and Siemens both released software patches this week, highlighting the need for quick responses from security teams. From the enterprise perspective, the response should go beyond just patching internal systems. Vulnerable third party business partners frequently provide cybercriminals with a path into the network of larger companies. Organizations should have a plan for ensuring their vendors and partners implement critical patches, especially for vendors with sensitive data like cloud providers.
