New Delhi police have arrested 63 suspects in the last two months working and operating 26 call centers that were engaging in tech support scams, posing as tech support staff at Microsoft, Google, Apple, and other major tech companies.
The raids on Delhi-based call centers have taken place over the last two months, Microsoft said. Police first raided 10 call centers and arrested 24 people in October, and then raided 16 other call centers and made 39 more arrests this week.
Microsoft said its staff received over 7,000 victim reports associated with the 16 call centers raided this week, from over 15 countries. Users reported paying between $100 and $500 for unnecessary tech support services and products.
The raids resulted in the seizure of substantial evidence including call scripts, live chats, voice call recordings and customer records from tech support fraud operations, Microsoft said.
The Delhi police’s crackdown on tech support call centers came after Microsoft filed legal complaints earlier this year. Microsoft has been collecting customer complaints about tech support scams since 2014, via its “Report a technical support scam” portal.
Tech support scams (also known as scareware) have been a huge problem for Windows users over the past two decades. According to a Microsoft survey’s results released at the start of 2018, three out of five Windows users encountered a tech support scam in the previous year. Overall, Microsoft said there was a five points reduction in the number of tech support scams going around, but the number was still high.
The company has been fighting against such scams since 2014, when it filed its first legal action in the US, but it announced renewed efforts to crack down on tech support scammers earlier this year in April.
Based on today’s news, it appears that the company has focused its efforts on tech support scams hosted abroad, after spending the last few years working with North American authorities on cracking down against tech support operations located in the US and Canada.
There are multiple variations of a tech support scam, but all are based around the concept of showing an alarming popup to a user to scare him/her in calling a tech support number to fix a non-existent problem.
There are tech support operations that rely on luring users on sites and showing the popups via the browser, there are tech support groups that show the popups at the OS level by using malware, and there are groups operating via emails or cold-calls, without showing any popups at all.
In some cases the call center operators ask for remote access to “infected” PCs, but not in all. The end goal in all these scams is to convince the user into paying for unnecessary tech support services or security software.
Below is the tried and tested advice that Microsoft has always given out to users over the past few years in regards to tech support scams, shady popups, or impromptu phone calls:
- Microsoft will never proactively reach out to you to provide unsolicited PC or technical support. Any communication we have with you must be initiated by you.
- Be wary of any unsolicited phone call or pop-up message on your device.
- Do not call the phone number in a pop-up window on your device and be cautious about clicking on notifications asking you to scan your computer or download software. Many scammers try to fool you into thinking their notifications are legitimate.
- Never give control of your computer to a third party unless you can confirm that it is a legitimate representative of a computer support team with whom you are already a customer.
- If skeptical, take the person’s information down and immediately report it to your local authorities.

Cloud Data Security
Data security has become an immutable part of the technology stack for modern applications. Protecting application assets and data against cybercriminal activities, insider threats, and basic human negligence is no longer an afterthought. It must be addressed early and often, both in the application development cycle and the data analytics stack.
The requirements have grown well beyond the simplistic features provided by data platforms, and as a result a competitive industry has emerged to address the security layer. The capabilities of this layer must be more than thorough, they must also be usable and streamlined, adding a minimum of overhead to existing processes.
To measure the policy management burden, we designed a reproducible test that included a standardized, publicly available dataset and a number of access control policy management scenarios based on real world use cases we have observed for cloud data workloads. We tested two options: Apache Ranger with Apache Atlas and Immuta. This study contrasts the differences between a largely role-based access control model with object tagging (OT-RBAC) to a pure attribute-based access control (ABAC) model using these respective technologies.
This study captures the time and effort involved in managing the ever-evolving access control policies at a modern data-driven enterprise. With this study, we show the impacts of data access control policy management in terms of:
- Dynamic versus static
In our scenarios, Ranger alone took 76x more policy changes than Immuta to accomplish the same data security objectives, while Ranger with Apache Atlas took 63x more policy changes. For our advanced use cases, Immuta only required one policy change each, while Ranger was not able to fulfill the data security requirement at all.
This study exposed the limitations of extending legacy Hadoop security components into cloud use cases. Apache Ranger uses static policies in an OT-RBAC model for the Hadoop ecosystem with very limited support for attributes. The difference between it and Immuta’s attribute-based access control model (ABAC) became clear. By leveraging dynamic variables, nested attributes, and global row-level policies and row-level security, Immuta can be quickly implemented and updated in comparison with Ranger.
Using Ranger as a data security mechanism creates a high policy-management burden compared to Immuta, as organizations migrate and expand cloud data use—which is shown here to provide scalability, clarity, and evolvability in a complex enterprise’s data security and governance needs.
The chart in Figure 1 reveals the difference in cumulative policy changes required for each platform configuration.

We strongly encourage you, as the reader, to discern for yourself what is of value. We hope this report is informative and helpful in uncovering some of the challenges and nuances of data governance platform selection. You are encouraged to compile your own representative use cases and workflows and review these platforms in a way that is applicable to your requirements.
GigaOm Radar for Data Loss Prevention
Data is at the core of modern business: It is our intellectual property, the lifeblood of our interactions with our employees, partners, and customers, and a true business asset. But in a world of increasingly distributed workforces, a growing threat from cybercriminals and bad actors, and ever more stringent regulation, our data is at risk and the impact of losing it, or losing access to it, can be catastrophic.
With this in mind, ensuring a strong data management and security strategy must be high on the agenda of any modern enterprise. Security of our data has to be a primary concern. Ensuring we know how, why, and where our data is used is crucial, as is the need to be sure that data does not leave the organization without appropriate checks and balances.
Keeping ahead of this challenge and mitigating the risk requires a multi-faceted approach. People and processes are key, as, of course, is technology in any data loss prevention (DLP) strategy.
This has led to a reevaluation of both technology and approach to DLP; a recognition that we must evolve an approach that is holistic, intelligent, and able to apply context to our data usage. DLP must form part of a broader risk management strategy.
Within this report, we evaluate the leading vendors who are offering solutions that can form part of your DLP strategy—tools that understand data as well as evaluate insider risk to help mitigate the threat of data loss. This report aims to give enterprise decision-makers an overview of how these offerings can be a part of a wider data security approach.
Key Criteria for Evaluating Data Loss Prevention Platforms
Data is a crucial asset for modern businesses and has to be protected in the same way as any other corporate asset, with diligence and care. Loss of data can have catastrophic effects, from reputational damage to significant fines for breaking increasingly stringent regulations.
While the risk of data loss is not new, the landscape we operate in is evolving rapidly. Data can leave data centers in many ways, whether accidental or malicious. The routes for exfiltration also continue to grow, ranging from email, USB sticks, and laptops to ever-more-widely-adopted cloud applications, collaboration tools, and mobile devices. This is driving a resurgence in the enterprise’s need to ensure that no data leaves the organization without appropriate checks and balances in place.
Keeping ahead of this challenge and mitigating the risk requires a multi-faceted approach. Policy, people, and technology are critical components in a data loss prevention (DLP) strategy.
As with any information security strategy, technology plays a significant role. DLP technology has traditionally played a part in helping organizations to mitigate some of the risks of uncontrolled data exfiltration. However, both the technology and threat landscape have shifted significantly, which has led to a reevaluation of DLP tools and strategy.
The modern approach to the challenge needs to be holistic and intelligent, capable of applying context to data usage by building a broader understanding of what the data is, who is using it, and why. Systems in place must also be able to learn when user activity should be classified as unusual so they can better interpret signs of a potential breach.
This advanced approach is also driving new ways of defining the discipline of data loss prevention. Dealing with these risks cannot be viewed in isolation; rather, it must be part of a wider insider risk-management strategy.
Stopping the loss of data, accidental or otherwise, is no small task.
