A novel cloud-native cryptojacking operation has set its eyes on uncommon Amazon Web Services (AWS) offerings such as AWS Amplify, AWS Fargate, and Amazon SageMaker to illicitly mine cryptocurrency. The malicious cyber activity has been codenamed  AMBERSQUID  by cloud and container security firm Sysdig. "The AMBERSQUID operation was able to exploit cloud services without triggering the AWS requirement for approval of more resources, as would be the case if they only spammed EC2 instances," Sysdig security researcher Alessandro Brucato said in a report shared with The Hacker News. "Targeting multiple services also poses additional challenges, like incident response, since it requires finding and killing all miners in each exploited service." Sysdig said it discovered the campaign following an analysis of 1.7 million images on Docker Hub, attributing it with moderate confidence to Indonesian attackers based on the use of Indonesian language in scripts and usernames.

  Threat actors' use of Cloudflare R2 to host phishing pages has witnessed a 61-fold increase over the past six months. "The majority of the phishing campaigns target Microsoft login credentials, although there are some pages targeting Adobe, Dropbox, and other cloud apps," Netskope security researcher Jan Michael said. Cloudflare R2 , analogous to Amazon Web Service S3, Google Cloud Storage, and Azure Blob Storage, is a data storage service for the cloud. The development comes as the total number of cloud apps from which malware downloads originate has increased to 167, with Microsoft OneDrive, Squarespace, GitHub, SharePoint, and Weebly taking the top five spots. The phishing campaigns identified by Netskope not only abuse Cloudflare R2 to distribute static phishing pages, but also leverage the company's Turnstile offering, a CAPTCHA replacement, to place such pages behind anti-bot barriers to evade detection. In doing so, it prevents online scanners like urlscan.io
