Learning from cryptocurrency mining attack scripts on Linux

Cryptocurrency mining attacks continue to represent a threat to many of our Azure Linux customers. In the past, we’ve talked about how some attackers use brute force techniques to guess account names and passwords and use those to gain access to machines. Today, we’re talking about an attack that a few of our customers have seen where a service is exploited to run the attackers code directly on the machine hosting the service.

This attack is interesting for several reasons. The attacker echoes in their scripts so we can see what they want to do, not just what executes on the machine. The scripts cover a wide range of possible services to exploit so they demonstrate how far the campaign can reach. Finally, because we have the scripts themselves, we can pull out good examples from the Lateral Movement, Defense Evasion, Persistence, and Objectives sections of the Linux MITRE ATT&CK Matrix and use those to talk about hunting on your own data.

Initial vector

For this attack, the first indication something is wrong in the audited logs is an echo command piping a base64 encoded command into base64 for decoding then piping into bash. Across our users, this first command

Azure is now certified for the ISO/IEC 27701 privacy standard

We are pleased to share that Azure is the first major US cloud provider to achieve certification as a data processor for the new international standard ISO/IEC 27701 Privacy Information Management System (PIMS). The PIMS certification demonstrates that Azure provides a comprehensive set of management and operational controls that can help your organization demonstrate compliance with privacy laws and regulations. Microsoft’s successful audit can also help enable Azure customers to build upon our certification and seek their own certification to more easily comply with an ever-increasing number of global privacy requirements.

Being the first major US cloud provider to achieve a PIMS certification is the latest in a series of privacy firsts for Azure, including being the first to achieve compliance with EU Model clauses. Microsoft was also the first major cloud provider to voluntarily extend the core data privacy rights included in the GDPR (General Data Protection Regulation) to customers around the world.

PIMS is built as an extension of the widely-used ISO/IEC 27001 standard for information security management, making the implementation of PIMS’s privacy information management system a helpful compliance extension for the many organizations that rely on ISO/IEC 27001, as well as creating a strong integration point

Trusted Cloud: security, privacy, compliance, resiliency, and IP

Can you trust your cloud provider? That’s a question being asked a lot of these days, and with the newest version of our popular white paper Trusted Cloud: Microsoft Azure security, privacy, compliance, resiliency, and protected IP we’ve worked to provide you answers.

When we first published Trusted Cloud in 2015, the paper was 13 pages long and covered security, privacy, and compliance. Since then we’ve updated Trusted Cloud several times, and our newest edition stretches to 42 pages and includes new sections on resiliency and intellectual property. We understand 42 pages is a lot, so now we’re also offering Trusted Cloud both as a single paper and as five separate papers.

 

Security. The updated security section covers the multiple services that make up our defense-in-depth approach to security, including new services like our Security Information and Event Management (SIEM) offering, Azure Sentinel.

Compliance. Azure now offers an industry-leading 92 compliance offerings. We’ve seen tremendous growth in this area since the 21 offerings listed in the original 2015 paper. We’ve also added new services like Azure Blueprints, which provides you with templates to create, deploy, and update fully governed cloud environments to help meet compliance requirements.

Privacy. Since

CIS Azure Security Foundations Benchmark open for comment
CIS Azure Security Foundations Benchmark open for comment

One of the best ways to speed up securing your cloud deployments is to focus on the most impactful security best practices. Best practices for securing any service begins with a fundamental understanding of cybersecurity risk and how to manage it. As an Azure customer, you can leverage this understanding by using security recommendations from Microsoft to help guide your risk-based decisions as they’re applied to specific security configuration settings in your environment.

We partnered with the Center for Internet Security (CIS) to create the CIS Microsoft Azure Foundations Benchmark v1.  Since that submission, we’ve received good feedback and wanted to share it with the community for comment in a document we call the Azure Security Foundations Benchmark. This benchmark contains recommendations that help improve the security of your applications and data on Azure. The recommendations in this document will go into updating the CIS Microsoft Azure Foundations Benchmark v1, and are anchored on the security best practices defined by the CIS Controls, Version 7.

In addition, these recommendations are or will be integrated into Azure Security Center and their impact will be surfaced in the Azure Security Center Secure Score and the Azure Security Center Compliance Dashboard.

SAP on Azure–Designing for availability and recoverability

This is the third in a four-part blog series on Designing a great SAP on Azure Architecture.

Robust SAP on Azure Architectures are built on the pillars of security, performance and scalability, availability and recoverability, efficiency and operations.

We covered designing for performance and scalability previously and within this blog we will focus on availability and recoverability.

Designing for availability

Designing for availability ensures that your mission critical SAP applications such as SAP ERP or S/4HANA have high-availability (HA) provisions applied. These HA provisions ensure the application is resilient to both hardware and software failures and that the SAP application uptime is secured to meet your service-level-agreements (SLAs).

Within the links below, you will find a comprehensive overview on Azure virtual machine maintenance versus downtime where unplanned hardware maintenance events, unexpected downtime and planned maintenance events are covered in detail.

From an availability perspective the options you have for deploying SAP on Azure are as follows:

Customer Provided Keys with Azure Storage Service Encryption

Azure storage offers several options to encrypt data at rest. With client-side encryption you can encrypt data prior to uploading it to Azure Storage. You can also choose to have Azure storage manage encryption operations with storage service encryption using Microsoft managed keys or using customer managed keys in Azure Key Vault. Today, we present enhancement to storage service encryption to support granular encryption settings on storage account with keys hosted in any key store. Customer provided keys (CPK) enables you to store and manage keys in on-premises or key stores other than Azure Key Vault to meet corporate, contractual, and regulatory compliance requirements for data security.

Customer provided keys allows you to pass an encryption key as part of read or write operation to storage service using blob APIs. Since the encryption key is defined at the object level, you can have multiple encryption keys within a storage account. When you create a blob with customer provided key, storage service persists the SHA-256 hash of the encryption key with the blob to validate future requests. When you retrieve an object, you must provide the same encryption key as part of the request. For example, if a blob is created

Measuring your return on investment of Azure as a compliance platform

Today we’re pleased to introduce the release of Microsoft Azure is Helping Organizations Manage Regulatory Challenges More Effectively, a new International Data Corporation (IDC) white paper based on original research by IDC and sponsored by Microsoft. IDC studied Azure customers who are using Azure as a platform to meet regulatory compliance needs, with a special focus on government, healthcare, and financial customers. Azure Policy was cited by customers as having an important impact on meeting compliance obligations.

IDC found that these customers are realizing significant benefits by leveraging Azure capabilities to make their regulatory and compliance efforts more effective. Significant findings of research include:

•    Five-year return on investment (ROI) of 465 percent, worth an average of $4.29 Million.
•    Six-month payback on investment.
•    47 percent reduction in unplanned downtime.
•    35 percent reduction in compliance-related penalties.
•    A 24 percent increase in productivity for regulatory compliance teams.

Research summary findings

“Study participants reported use of Azure as a compliance platform helped them carry out their day–to-day compliance responsibilities more effectively. Azure helped them better manage spikes in the workload, enabled faster access to (and analysis of) data during audits, and reduced exposure to risk based on the
