Serverless | Breaking Cybersecurity News | The Hacker News

A Latin America (LATAM)-based financially motivated actor codenamed FLUXROOT has been observed leveraging Google Cloud serverless projects to orchestrate credential phishing activity, highlighting the abuse of the cloud computing model for malicious purposes. "Serverless architectures are attractive to developers and enterprises for their flexibility, cost effectiveness, and ease of use," Google said in its biannual Threat Horizons Report [PDF] shared with The Hacker News. "These same features make serverless computing services for all cloud providers attractive to threat actors, who use them to deliver and communicate with their malware, host and direct users to phishing pages, and to run malware and execute malicious scripts specifically tailored to run in a serverless environment." The campaign involved the use of Google Cloud container URLs to host credential phishing pages with the aim of harvesting login information associated with Mercado Pago, an onli...

A first-of-its-kind malware targeting Amazon Web Services' (AWS) Lambda serverless computing platform has been discovered in the wild. Dubbed "Denonia" after the name of the domain it communicates with, "the malware uses newer address resolution techniques for command and control traffic to evade typical detection measures and virtual network access controls," Cado Labs researcher Matt Muir  said . The  artifact  analyzed by the cybersecurity company was uploaded to the VirusTotal database on February 25, 2022, sporting the name "python" and packaged as a 64-bit  ELF  executable. However, the filename is a misnomer, as Denonia is programmed in Go and harbors a customized variant of the XMRig cryptocurrency mining software. That said, the mode of initial access is unknown, although it's suspected it may have involved the compromise of AWS Access and Secret Keys. Another notable feature of the malware is its use of DNS over HTTPS ( DoH ) for c...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...
