Next generation of phishing attacks uses unexpected delivery methods to steal data

 


Netskope, a specialist in secure access service edge (SASE), has unveiled new research that shows how the prevalence of cloud applications is changing the way threat actors are using phishing attack delivery methods to steal data. 

The Netskope Cloud and Threat Report: Phishing details trends in phishing delivery methods such as fake login pages and fake third-party cloud applications designed to mimic legitimate apps, the targets of phishing attacks, where the fraudulent content is hosted, and more.

Although email is still a primary mechanism for delivering phishing links to fake login pages to capture usernames, passwords, MFA codes and more, the report reveals that users are more frequently clicking phishing links arriving through other channels, including personal websites and blogs, social media, and search engine results. The report also details the rise in fake third-party cloud apps designed to trick users into authorizing access to their cloud data and resources.

Phishing Comes From All Directions

Traditionally considered the top phishing threat, 11% of the phishing alerts were referred from webmail services, such as Gmail, Microsoft Live, and Yahoo. Personal websites and blogs, particularly those hosted on free hosting services, were the most common referrers to phishing content, claiming the top spot at 26%. The report identified two primary phishing referral methods: the use of malicious links through spam on legitimate websites and blogs, and the use of websites and blogs created specifically to promote phishing content.

Search engine referrals to phishing pages have also become common, as attackers are weaponising data voids by creating pages centred around uncommon search terms where they can readily establish themselves as one of the top results for those terms. Examples identified by Netskope Threat Labs include how to use specific features in popular software, quiz answers for online courses, user manuals for a variety of business and personal products, and more.

Ray Canzanese, threat research director, Netskope Threat Labs, said: “Business employees have been trained to spot phishing messages in email and text messages, so threat actors have adjusted their methods and are luring users into clicking on phishing links in other, less expected places.

“While we might not be thinking about the possibility of a phishing attack while surfing the internet or favourite search engine, we all must use the same level of vigilance and skepticism as we do with inbound email, and never enter credentials or sensitive information into any page after clicking a link. Always browse directly to login pages.” 

The Rise of Fake Third-Party Cloud Apps

Netskope’s report discloses another key phishing method: tricking users into granting access to their cloud data and resources through fake third-party cloud applications. This early trend is particularly concerning because access to third-party applications is ubiquitous and poses a large attack surface. On average, end-users in organisations granted more than 440 third-party applications access to their Google data and applications, with one organisation having as many as 12,300 different plugins accessing data – an average of 16 plugins per user. Equally as alarming, over 44% of all third-party applications accessing Google Drive have access to either sensitive data or all data on a user’s Google Drive – further incentivising criminals to create fake third-party cloud apps.  

“The next generation of phishing attacks is upon us. With the prevalence of cloud applications and the changing nature of how they are used, from Chrome extensions or app add-ons, users are being asked to authorise access in what has become an overlooked attack vector,” added Canzanese. “This new trend of fake third-party apps is something we’re closely monitoring and tracking for our customers. We expect these types of attacks to increase over time, so organisations need to ensure that new attack paths such as OAuth authorisations are restricted or locked down. Employees should also be aware of these attacks and scrutinise authorisation requests the same way they scrutinise emails and text messages.” 

Within the report, Netskope Threat Labs includes actionable steps organisations can take to identify and control access to phishing sites or applications, such as deploying a security service edge (SSE) cloud platform with a secure web gateway (SWG), enabling zero trust principles for least privilege access to data and continuous monitoring, and using Remote Browser Isolation (RBI) to reduce browsing risk for newly-registered domains.      

Additional key findings from the report include: 

  • Employees continue to click, fall victim to malicious links. It is widely understood that it takes just one click to severely compromise an organisation. While enterprise phishing awareness and training continues to be more prevalent, the report reveals that an average of eight out of every 1,000 end-users in the enterprise clicked on a phishing link or otherwise attempted to access phishing content.
  • Users are being lured by fake websites designed to mimic legitimate login pages. Attackers primarily host these websites on content servers (22%) followed by newly registered domains (17%). Once users put personal information into a fake site, or grant it access to their data, attackers are able to capture usernames, passwords, and multi-factor authentication (MFA) codes. 
  • Geographic location plays a role in the access rate of phishing. Africa and the Middle East were the two regions with the highest percentages of users accessing phishing content. In Africa, the percentage of users accessing phishing content is more than 33% above average, and in the Middle East, it is more than twice the average. Attackers frequently use fear, uncertainty, and doubt (FUD) to design phishing lures and also try to capitalise on major news items. Especially in the Middle East, attackers appear to be having success designing lures that capitalise on political, social, and economic issues affecting the region.

Distribute low-latency broadcast content in AWS using JPEG XS and AWS CDI

Introduction

Live production workflows are one of the most demanding workloads for broadcasters. Broadcasters require low latency, agility, scalability, and reliability to deliver live content like news and sporting events to consumers. Amazon Web Services (AWS) developed the AWS Cloud Digital Interface (CDI) SDK as an open-source project to help the media and entertainment industry with contribution and distribution workflows that provide high performance cloud networking between cloud applications.

AWS CDI is a network technology that allows for reliable transport of high-quality uncompressed video within AWS. It can be used to send video between applications with network latency as low as 8 milliseconds, which is less than one frame per second. Ground-to-cloud, cloud-to-cloud, and cloud-to-ground contribution and distribution workloads that require minimal artifacts and latency can leverage JPEG XS. JPEG XS is a visually lossless, low complexity, and low latency video codec that can transport over IP using the SMPTE 2110-22 standard. This also allows for the flexible transport of video, audio, and ancillary data separately using the SMPTE 2110 suite. With the combination of JPEG XS and AWS CDI, broadcasters can move live production workflows into the cloud and continue to maintain high-quality, low-latency content delivery while building end-to-end video solutions.

AWS Media Services support both CDI and JPEG XS to help enable live production workflows in AWS (learn more in the What’s New post). This blog post focuses on AWS Elemental MediaConnect and various use cases where it can be leveraged for production contribution and distribution workflows.

The scenarios highlighted in this blog exemplify various workflows using virtual private cloud (VPC) peering or AWS Organizations with Resource Access Manager (RAM). VPC peering is a networking connection between two VPCs that enables you to route traffic between them, either within a single account or another AWS account. AWS Organizations with RAM allows customers to use a single organization unit, with multi-account AWS environments for central governance and management. Resources are shared to minimize the cost and impact of any issues that arise.

This blog covers the following use cases for CDI/JPEG-XS workflows via MediaConnect:

  • Routing JPEG XS signals across different subnets
  • Routing JPEG XS/CDI signals across two AWS accounts with central governance
    • Leveraging MediaConnect with JPEG-XS (light compression)
    • Leveraging MediaConnect with CDI (uncompressed)

Routing JPEG XS signal across different subnets

When customers operating in independent AWS accounts need to share content inter and/or intra region, VPC peering can be used as depicted in figure 1. This scenario can benefit broadcasters who distribute to various distribution endpoints such as remote broadcast sites and local stations. JPEG XS can also be used in live cloud-based broadcast and production where content is sent downstream to another VPC for remote monitoring.

Figure 1. JPEG XS distribution using VPC peering

Routing JPEG XS/CDI signals across two AWS accounts with central governance

This scenario is for teams that operate independently but have a single organization and single payer configured using Resource Access Manager (RAM). RAM allows multi-AWS account environments with central governance and management. Resources are shared to minimize cost and impact of issues that arise. This scenario is useful for management and execution of multiple deployment stages (production, development, and testing). Account one acts as the source provider for account two’s environment. By sharing resources such as a subnet, CDI can be transported easily.

Figure 2. JPEG XS distribution using Resource Access Manager

VPC sharing allows customers to share subnets with other AWS accounts within the same AWS organization. This is a very powerful concept with a number of benefits:

  • Separation of duties: centrally controlled VPC structure, routing, IP address allocation
  • Application owners continue to own resources, accounts, and security groups
  • VPC sharing participants can reference security group IDs of one another
  • Efficiency gains: higher density in subnets, efficient use of VPNs and AWS Direct Connect
  • Hard limits can be avoided; for example, 50 VIFs per AWS Direct Connect connection through simplified network architecture
  • Costs can be optimized through reuse of NAT gateways, VPC interface endpoints, and intra-Availability Zone traffic

Conclusion

In this post, we explain various ways AWS Elemental MediaConnect can distribute JPEG XS and/or CDI workflows in the cloud. Key factors to consider when deciding upon a distribution approach are:

  • Content type and media format, compressed vs. non-compressed
  • Currently MediaConnect supports support up to 10 CDI outputs at 1080P. For 4Kp60, you can have up to 10 ST 2110 JPEG XS outputs, but only 4 CDI outputs.

AWS Professional Services specializing in media and entertainment is ready to help you discover and develop the best approach that fits your unique needs. For more information, visit AWS Professional Services or reach out directly through your account manager.

What is the difference between cloud computing and virtualization?

Understanding the distinctions is essential for companies looking to modernize and maximize resources.

Hand showing laptop computer with cloud.

Cloud computing and virtualization are not interchangeable terms, nor are they two different options to choose from when building your IT environment, system or networks. Virtualization was created in the 1960s to maximize hardware resources by creating a virtual layer on top of a host or a computer. Virtualization is at the core of cloud computing. Thanks to it, cloud vendors can provide a wide range of different services, operating systems and other virtual machines while maximizing data centers.

What is cloud computing?

Cloud computing revolutionized IT infrastructures by removing hardware and software costs from the equation and allowing customers to access these resources via the internet. Cloud computing resources include physical and virtual services, applications, data storage, development tools, AI-powered services and VMs.

Cloud assets are hosted at cloud data centers and managed by cloud service providers. Cloud computing allows companies to pay only for what they use, operate with high levels of security, automate with inbuilt cloud features and leverage innovations like machine learning.

Cloud computing can run on public clouds offered by vendors like Google Cloud, Microsoft Azure Cloud and Amazon Web Services, or on private clouds.

Key features of cloud computing

  • Lowers costs while improving access to technology: Cloud computing allows organizations to access the latest technology while not investing in the expensive hardware and software that powers innovations.
  • Improves deployment and return on investment: Deploying IT systems in the cloud drastically reduces the time it takes for companies to begin operating, and it rapidly impacts performance and returns on investment.
  • Services, scale, support and security: Cloud vendors offer a wide range of services, full support for all level workers and built-in security, and these features reduce costs and can help improve business and strengthen its security posture — scaling in the cloud can be done in just a few clicks.
  • Virtualized IT: With cloud computing, organizations can quickly create their virtualized IT infrastructure — servers, operating systems, software, networks and other infrastructure.


What is virtualization?

Virtualization is the creation of VMs layered over a host. Using software called a hypervisor, users can create several VMs on their data servers, computers or hosts. For example, with virtualization, if a customer needs to run three different operating systems, macOS, Windows and Linux, instead of having to power up three machines, the user can create them virtually in just one data center or host.

While anyone can create their VM, in cloud computing, virtualization is taken to the limit. Virtualization is the essence of cloud computing. Cloud vendors make the most of their data centers and hosts by offering all kinds of VMs that can be deployed with just a few clicks. Virtualization not only saves time and money. VMs can move from one host to another almost instantly, avoiding the risks of downtime if one host shuts down.

The software that coordinates VMs on a host is called a hypervisor. It acts as an interface between the physical hardware and the VMs, ensuring all VMs have the processing power and resources they need from the hardware. VMs are, as the term implies, a device that only exists virtually, in the form of software. VMs can replicate operating systems or create virtual networks.

Type 1 hypervisors or “bare-metal” are the most common hypervisors used to create VM. They interact directly with the hardware and physical resources replacing the traditional operating system. Type 2 hypervisors run as an application on the OS installed in the main hardware and are primarily used in endpoint devices to run an alternative OS.

Key features of virtualization

  • Virtual machines: Virtualization creates VMs on main hosts.
  • Agility and performance: The ability to create VMs on one hardware gives companies endless possibilities to maximize resources.
  • Saves costs: Virtualization saves costs by creating VMs and IT infrastructure on the cloud or other data centers, and VMs also improve disaster recovery and business continuity.
  • Virtual OS and Virtual Networks: Organizations can leverage different OS and networks by deploying VMs, and this allows them to build sophisticated IT architectures while keeping costs low.
  • Support DevOps: VMs can easily be turned off or on, migrated and adapted, providing maximum flexibility for development, and they can also serve to test environments, rapidly migrate and consolidate systems in one server.

How do cloud computing and virtualization differ?

Without the concept of virtualization, there would be no cloud computing. The difference between cloud computing and virtualization is that the first is a term reserved for computing resources that are accessible on-demand via the internet. In contrast, virtualization refers to simply creating VMs that are solely software layered on top of a host or main hardware.

On the other hand, cloud computing is a broader term that encompasses everything that the cloud offers, from data storage to AI analytics. Cloud computing is a service usually offered to customers as Infrastructure as a Service, Platform as a Service and Software as a Service. While virtualization may also be provided as a service, it is more commonly used as a technical term. The term defines how hardware resources are used to create virtual networks and VMs.

Cloud computing: Migration is not stopping and there's no going back

Cloud computing spending continues to rise – and once apps have moved to the cloud, they tend to stay there.


Tech analyst Gartner is predicting that spending on public cloud computing services will grow 20.7% in 2023 to $591.8 billion – up from the $490 billion predicted for 2022, which Gartner says represents a growth rate of 18.8%. 

The world, arguably, has become a trickier place to predict these days with so many concurrent global events happening. Amazon's latest forward-looking statement lists COVID-19, exchange rates, geopolitical tensions, recession, inflation, interest rates, global labor shortages and supply chain issues, world events, the rate of growth of the internet, e-commerce and cloud as factors impacting its guidance.  

Gartner's analysts offer an outlook for public cloud spending, which reflects some of this uncertainty.

"Current inflationary pressures and macroeconomic conditions are having a push and pull effect on cloud spending," Sid Nag, vice president analyst at Gartner, said in a press release

"Cloud computing will continue to be a bastion of safety and innovation, supporting growth during uncertain times due to its agile, elastic and scalable nature."

Amazon last week reported AWS revenue growth slowed in the third quarter to 27.5%. It missed analysts estimates and was the slowest year-on-year growth since 2014. AWS was launched in 2006. Microsoft Azure and other cloud services revenue growth for Q1 fiscal 2023 was up 35%. Microsoft doesn't break out numbers specific to Azure.   

Microsoft Azure and Google Cloud are slowly taking share from AWS, but AWS is still the giant in public cloud, with 38.9% share of worldwide revenues in 2021, according to Gartner. Microsoft has a 21.1% share, followed by Alibaba at 9.5% and Google at 7.1%. 

Gartner's current forecast for public cloud spending includes cloud business process services (BPaaS), cloud application infrastructure services (PaaS), cloud application services (SaaS), cloud management and security services, cloud system infrastructure services (IaaS), and desktop-as-a-service (DaaS). 

The biggest categories are SaaS, IaaS, and PasS. Gartner forecasts 23.2% growth for PaaS and 16.8% for SaaS in 2023, but it also sees challenges from inflation and hiring. 

"Cloud migration is not stopping," said Nag. "IaaS will naturally continue to grow as businesses accelerate IT modernization initiatives to minimize risk and optimize costs. Moving operations to the cloud also reduces capital expenditures by extending cash outlays over a subscription term, a key benefit in an environment where cash may be critical to maintain operations.

"Higher-wage and more skilled staff are required to develop modern SaaS applications, so organizations will be challenged as hiring is reduced to control costs. But since PaaS can facilitate more efficient and automated code generation for SaaS applications, the rate of PaaS consumption will consequently increase."

Nag still sees spending on public cloud rising despite growth, profitability and competition pressures. There's also an element of lock-in, not to a specific vendor but by shifting workloads to the cloud, after which they are unlikely to move back to on-premise systems.

"Once applications and workloads move to the cloud they generally stay there, and subscription models ensure that spending will continue through the term of the contract and most likely well beyond. For these vendors, cloud spending is an annuity – the gift that keeps on giving," said Nag.

High data visibility delivers better business outcomes

Enterprises pick up data from disparate sources and its visibility is very critical for them.  There is a significant rise in cloud-based workloads across organizations and the top priority for cloud users is to increase cloud visibility to ensure greater operational control.  The extent of ease by which businesses can monitor their data and analyze it indicates data visibility.  The higher the data visibility, the chances of taking informed decisions are greater. Network visibility equips the IT teams to become more aware of the data, components, and other network content within any enterprise computer network.  

Studies show a majority of companies have low visibility into their public cloud environments and the tools and data supplied by cloud providers are insufficient.  Lack of visibility can lead to the masking of security threats, operational control challenges, application performance issues, and a decrease in business value.  This implies organizations should have comprehensive cloud visibility to maintain performance and cloud security.

Network performance depends on network visibility

Enterprises today have complex networks operating across multi-cloud and hybrid cloud environments, multiple data centers, and other connected devices.  Network performance is defined by both qualitative and quantitative processes and enables the network administrator to evaluate and improve the network services further.  To achieve this, data visibility is critical where administrators have to methodically search through the data, monitor bandwidth usage, and troubleshoot network performance issues.  With better network visibility, application downtime or outages are reduced. Due to its transparent feature or transparency across all levels of the network, it provides a bird’s eye view of the status of any ongoing project, leading to on-time delivery.  Team performance, resource allocation, and other financial implications can be easily tracked, and informed decisions taken by addressing potential risks if any.  It enables technical issues to be diagnosed remotely where appropriate solutions can be put in place.  The efficiency and effectiveness of the teams increase.  Visibility can also help in better application performance monitoring while enhancing the end-user experience.

Powerful network visualization tools can help in this regard to identify performance issues.  Data flow, from and to nodes and different devices can be monitored.  These tools will access the databases or cloud storage platforms and use the data there to map the network.  This could deliver a single-page view that accelerates the process of addressing issues.

Network visibility enhances threat detection and response

As the threat landscape expands, getting more complex and dynamic, network threat detection and response becomes more challenging.  The increasing blind spots across the network could lead to security compromises.  The business impact due to this will include, customer and revenue loss besides making a dent in the brand reputation.  Furthermore, cloud adoption, remote working environments, BYOD deployment, and exploding IoT devices are all making it a challenge to maintain comprehensive visibility across the network. Establishing network visibility is much required to begin with as it helps in bridging the gaps that other tools fail to offer. End-to-end visibility across the network would equip security analysts with inputs that are required to identify and address threats effectively.  Yes, data visibility should be at the core of the cyber security strategy as this will provide an understanding of where the network is potentially vulnerable and the immediate need to protect those areas. It helps to get control over the landscape and identify where data is being accessed or transformed, proactively securing it to eliminate future unauthorized access. This empowers the security teams to make the much-needed structural changes in the cyber-security strategy as well.  

Implementation of network visibility solutions can also address the under-skilled and understaffed Security Operations Center.

A robust network visibility architecture should ensure flexibility, sustainability, and scalability that eventually lead to better business outcomes. The flexibility of the technologies can help in adapting to the changes in the network.  They should be upgradeable if required to accommodate increasing speeds or new components.  Network visibility tools should also be able to accommodate the increasing connectivity speeds and the size of the networks.

Here's how Amazon plans to equip 29 million people with cloud-computing skills by 2025

Three new Amazon Web Services programs will offer free training to help people get jobs in cloud computing.

Amazon has announced three new initiatives as part of its effort to provide 29 million people with cloud-computing skills by 2025: IT Skills 4U, the AWS re/Start Associate initiative, and the opening of an AWS Skills Center in Arlington, Virginia.

Amazon Web Services' (AWS) IT Skills4U program is designed for displaced Ukrainian refugees in need of career support. The program offers training for Ukrainians with little to no tech experience and those with professional experience looking to re-enter the workforce, with the chance to earn AWS certifications upon completion.

The AWS re/Start Associate initiative is an expansion of Amazon's existing AWS re/Start program. The revamped program includes new goals to help underemployed individuals get started in cloud careers. It offers upskilling opportunities for underemployed individuals with legacy IT skills, like COBOL, SNA, and VTAM programming.

AWS' Skills Center in Arlington, VA, meanwhile, is an in-person learning space where community members can enroll in free classes to learn how cloud computing works in gaming, machine learning, robotics, smart home technologies, and space. The center will offer training and resources to help candidates earn a AWS Cloud Practitioner Essentials Certification, and will facilitate career coaching and host networking events with local employers and organizations.

The Arlington center is AWS's second dedicated in-person learning space, following the 2021 opening of the AWS Skills Center in Seattle, Washington. It will open to the public on October 18.     

All initiatives in AWS's education programs are free. The company has pledged billions of dollars to upskill existing IT workers and train new ones to become cloud-computing experts, claiming that digital skills in cloud architecture and software development add an estimated $6.3 trillion annually to global GDP.

According to a survey of 30,000 workers and 13,000 hiring managers in 19 countries by AWS and Gallup, businesses with a highly skilled digital workforce report revenues 168% higher than companies with a low level of digital skills..

The survey also found that companies with employees who possess advanced digital skills, such as cloud engineering, are 50% more likely to innovate. Companies that operate on the cloud reported experiencing innovation during the past two years – innovating five times faster than companies that don't use cloud technology.

Not only are tech-savvy companies more innovative, they're also happier, the survey found. For employees trained in advanced digital technologies, 72% reported high job satisfaction, and 72% said they had high confidence in their job security.

Companies are thinking of ways to harness emerging technologies to drive their company forward: 66% of surveyed employers said that, of blockchain, AI and the metaverse, at least one was likely to become integrated into everyday business.
