Spam email: Why do we still click on the link
As security gets tighter, the easiest way to get malware onto a PC is to trick the person at the keyboard.

Cyberattackers and scammers will try every trick in the book to lure you into parting with your information.

Data can be considered something of currency in itself; it can be sold on for profit in the underground, used to compromise online accounts, and in the worst cases, can be utilized for identity theft or making fraudulent purchases.

Software and web vulnerabilities are often exploited in attacks in order to collect data in bulk. Hardly a day goes by when you do not hear of yet another data breach with so-many-millions of records exposed.

On an individual level, the services we use on a daily basis are also of interest to scammers and attackers keen to get their hands on your information — and calendar systems are not exempt.

Calendar-based attacks and scams have been floating around the Internet for years, but it was only in 2016 when such schemes began to impact users in vast numbers. Apple device users began receiving notifications on their Calendar app, made possible through unprotected sharing mechanisms.

In one case noted by ZDNet, an advert for ‘Ray-Bans’ popped up and those that fell victim for the invite ended up having their credit card details stolen.

At the time, Apple rolled out a report function for spam notifications appearing in Calendar, Photos, and iMessage and later included a feature to turn off the automatic addition of events altogether. However, this patch-over only highlighted an ongoing problem impacting not just the iPhone and iPad maker, but Google and Microsoft too.

In the name of collaboration, invitations which appear on your calendar can be useful functions, especially for those in business and management. However, scam artists exploit what are usually valuable features for users.

Back in February, researchers from GreatHorn came across a Microsoft scam which used the spoofed name and email address of a chief executive at the company they were targeting.

Victims were sent a calendar invitation relating to a fake meeting organized by the ‘CEO,’ and those that clicked the link were taken to a phishing website designed to look like Microsoft Outlook for the purpose of stealing their account credentials.

Now, it appears scammers are targeting Google Calendar. Kaspersky researchers said on Monday that multiple cases of the latest invite scheme were detected throughout May, in which fraudsters sent unsolicited event invitations by abusing a “free online calendar service that adds invitations and events to users’ calendars automatically.”

The spam message blast exploited a smartphone-based feature for Gmail which automatically added and notified potential victims of the fraudulent calendar invitations.

These pop-up notifications were not as sophisticated as the aforementioned business scam which pretended to be legitimate communication from a CEO; rather, the invitations they connected to contained a phishing link which sent victims to a survey website offering money for questionnaire completion.

However, to receive their winnings, the victims would need to enter their credit card details alongside names, phone numbers, and addresses.

“The ‘calendar scam’ is a very effective scheme, as most people have become used to receiving spam messages from emails or messenger apps,” said Maria Vergelis, security researcher at Kaspersky. “So far, the sample we’ve seen contains text displaying an obviously weird offer, but as it happens, every simple scheme becomes more elaborate and trickier with time.”

Calendar abuse isn’t going away anytime soon, but thankfully for Google Calendar users, there is an easy way to prevent these annoying — and often malicious — campaigns. Open up Google Calendar, click Settings, and uncheck the box next to “Events from Gmail / Add automatically.”

Key Criteria for Evaluating Security Information and Event Management Solutions (SIEM)

Published

on

Security Information and Event Management (SIEM) solutions consolidate multiple security data streams under a single roof. Initially, SIEM supported early detection of cyberattacks and data breaches by collecting and correlating security event logs. Over time, it evolved into sophisticated systems capable of ingesting huge volumes of data from disparate sources, analyzing data in real time, and gathering additional context from threat intelligence feeds and new sources of security-related data. Next-generation SIEM solutions deliver tight integrations with other security products, advanced analytics, and semi-autonomous incident response.

SIEM solutions can be deployed on-premises, in the cloud, or a mix of the two. Deployment models must be weighed with regard to the environments the SIEM solution will protect. With more and more digital infrastructure and services becoming mission critical to every enterprise, SIEMs must handle higher volumes of data. Vendors and customers are increasingly focused on cloud-based solutions, whether SaaS or cloud-hosted models, for their scalability and flexibility.

The latest developments for SIEM solutions include machine learning capabilities for incident detection, advanced analytics features that include user behavior analytics (UBA), and integrations with other security solutions, such as security orchestration automation and response (SOAR) and endpoint detection and response (EDR) systems. Even though additional capabilities within the SIEM environment are a natural progression, customers are finding it even more difficult to deploy, customize, and operate SIEM solutions.

Other improvements include better user experience and lower time-to-value for new deployments. To achieve this, vendors are working on:

  • Streamlining data onboarding
  • Preloading customizable content—use cases, rulesets, and playbooks
  • Standardizing data formats and labels
  • Mapping incident alerts to common frameworks, such as the MITRE ATT&CK framework

Vendors and service providers are also expanding their offerings beyond managed SIEM solutions to à la carte services, such as content development services and threat hunting-as-a-service.

There is no one-size-fits-all SIEM solution. Each organization will have to evaluate its own requirements and resource constraints to find the right solution. Organizations will weigh factors such as deployment models or integrations with existing applications and security solutions. However, the main decision factor for most customers will revolve around usability, affordability, and return on investment. Fortunately, a wide range of solutions available in the market can almost guarantee a good fit for every customer.

Key Criteria for Evaluating Secure Service Access

Published

on

Since the inception of large-scale computing, enterprises, organizations, and service providers have protected their digital assets by securing the perimeter of their on-premises data centers. With the advent of cloud computing, the perimeter has dissolved, but—in most cases—the legacy approach to security hasn not. Many corporations still manage the expanded enterprise and remote workforce as an extension of the old headquarters office/branch model serviced by LANs and WANs.

Bolting new security products onto their aging networks increased costs and complexity exponentially, while at the same time severely limiting their ability to meet regulatory compliance mandates, scale elastically, or secure the threat surface of the new any place/any user/any device perimeter.

The result? Patchwork security ill-suited to the demands of the post-COVID distributed enterprise.

Converging networking and security, secure service access (SSA) represents a significant shift in the way organizations consume network security, enabling them to replace multiple security vendors with a single, integrated platform offering full interoperability and end-to-end redundancy. Encompassing secure access service edge (SASE), zero-trust network access (ZTNA), and extended detection and response (XDR), SSA shifts the focus of security consumption from being either data center or edge-centric to being ubiquitous, with an emphasis on securing services irrespective of user identity or resources accessed.

This GigaOm Key Criteria report outlines critical criteria and evaluation metrics for selecting an SSA solution. The corresponding GigaOm Radar Report provides an overview of notable SSA vendors and their offerings available today. Together, these reports are designed to help educate decision-makers, making them aware of various approaches and vendors that are meeting the challenges of the distributed enterprise in the post-pandemic era.

Key Criteria for Evaluating Edge Platforms

Published

on

Edge platforms leverage distributed infrastructure to deliver content, computing, and security closer to end devices, offloading networks and improving performance. We define edge platforms as the solutions capable of providing end users with millisecond access to processing power, media files, storage, secure connectivity, and related “cloud-like” services.

The key benefit of edge platforms is bringing websites, applications, media, security, and a multitude of virtual infrastructures and services closer to end devices compared to public or private cloud locations.

The need for content proximity started to become more evident in the early 2000s as the web evolved from a read-only service to a read-write experience, and users worldwide began both consuming and creating content. Today, this is even more important, as live and on-demand video streaming at very high resolutions cannot be sustained from a single central location. Content delivery networks (CDNs) helped host these types of media at the edge, and the associated network optimization methods allowed them to provide these new demanding services.

As we moved into the early 2010s, we experienced the rapid cloudification of traditional infrastructure. Roughly speaking, cloud computing takes a server from a user’s office, puts it in a faraway data center, and allows it to be used across the internet. Cloud providers manage the underlying hardware and provide it as a service, allowing users to provision their own virtual infrastructure. There are many operational benefits, but at least one unavoidable downside: the increase in latency. This is especially true in this dawning age of distributed enterprises for which there is not just a single office to optimize. Instead, “the office” is now anywhere and everywhere employees happen to be.

Even so, this centralized, cloud-based compute methodology works very well for most enterprise applications, as long as there is no critical sensitivity to delay. But what about use cases that cannot tolerate latency? Think industrial monitoring and control, real-time machine learning, autonomous vehicles, augmented reality, and gaming. If a cloud data center is a few hundred or even thousands of miles away, the physical limitations of sending an optical or electrical pulse through a cable mean there are no options to lower the latency. The answer to this is leveraging a distributed infrastructure model, which has traditionally been used by content delivery networks.

As CDNs have brought the internet’s content closer to everyone, CDN providers have positioned themselves in the unique space of owning much of the infrastructure required to bring computing and security closer to users and end devices. With servers close to the topological edge of the network, CDN providers can offer processing power and other “cloud-like” services to end devices with only a few milliseconds latency.

While CDN operators are in the right place at the right time to develop edge platforms, we’ve observed a total of four types of vendors that have been building out relevant—and potentially competing—edge infrastructure. These include traditional CDNs, hyperscale cloud providers, telecommunications companies, and new dedicated edge platform operators, purpose-built for this emerging requirement.
