The Ins and Outs of Ransomware-Attacks in Sri Lanka

The Ins and Outs of Ransomware-Attacks in Sri Lanka

A few years ago, Sri Lankan enterprises were fortunate that they only had to learn about cyber-attacks, such as ransomware, through media and Tech blogs, depicting horrifying stories on how such attacks brought large enterprises to their knees. Attackers forced helpless organizations, which were large in size and significant in terms of brand, to pay massive amounts of ransom to retrieve their stolen data. These organizations were heavily dependent on information technology to carry out their work. Many of us didn’t think such attacks would hit home due to a perception that we may be less appealing to such attackers. But that has changed. The question that organizations face is not “if a cyber-attack will happen?” rather “when will a cyber-attack happen?”

Many customers have recently reached out to us when they were hit by such an attack or when they suspected they were being attacked. Therefore, we have had our fare-share of experience in helping organizations to identify, respond, protect themselves, and recover from these cyber security incidents. When there’s news of a cyber-attack close to home, customers often reach out to us and ask questions such as – What actually happened, Do you know how we can check if we will be targeted, What do we need to do to make sure we will not be victims. Taking all of this into consideration, we wanted to share our experiences in dealing with such attacks, explain how these generally happen and possible preventive measures you can take to protect your organization.

From what we’ve gathered, most of these attacks have the following major steps, which I have explained below:

1. Initial compromise
2. Privilege escalation
3. Lateral movement
4. Persistence
5. Data theft (Less Common)
6. Payload detonation

The Initial Compromise is where the attackers gain access into your network, and there could be many ways in which this could happen. It could be as easy as brute forcing a Remote Desktop (RDP) session you have opened to the Internet to help with your remote working or it could by exploiting any zero-day vulnerability (or a very recently discovered vulnerability which hasn’t been patched) of your Internet facing webserver. A few ways to reduce the risk of the initial compromise is to expose Remote Sessions via a secure remote access VPN (with multifactor authentication), make sure you regularly patch your Internet server and ensure you do not expose unwanted services to the Internet.

Once the attacker gains access to your network, they explore to understand what sort of activities can be performed on that network. In most cases, the attacker tends to perform what’s called Privilege Escalation – in simpler terms, this means they try to elevate their level of access. To do this, they would try out methods such as guessing the passwords (Yes, mycompany@123 can be a very common password) or look for passwords stored in text files (Yes, this sounds very trivial, but the truth is when administrators force you to maintain strong passwords we often resort to simple means of remembering them, i.e. text files) or more complex methods such as running exploitation tools like mimikatz to steal credentials. The higher the access the attacker gets, the more damage they can do to a network. As a preventive measure, you can always try to force users to use complex passwords and educate them on how to keep the passwords safe. You could also monitor your user activity to detect abuse and misuse.

The next step of the attack is the Lateral Movement. In other words, once the attacker gains higher privileges on your network, it starts spreading the payload to all possible victim devices to cause more harm than damaging a single machine. Many would ask what makes a ransomware attack so devastating? The answer is its behavior of launching attacks on multiple devices within a small timeframe. This is what makes them so devastating and enables them to bring down organizations within a few minutes or hours. Most attackers utilize vulnerabilities on your network (e.g. the eternalblue exploit) or they would abuse legitimate tools to spread the payload. The abuse of legitimate tools can be very hard to detect as in most cases since the activity is done in such a manner that it mimics legitimate user behavior. Therefore, it’s very difficult to differentiate if the entire activity is malicious or not without proper context. For example, consider an attacker gaining access to the server that you use to distribute software in your organization. They can use this same tool to distribute the malware as well. A few methods of detecting and preventing lateral movement would be to properly segment user privileges, make sure all your devices have UpToDate security patches, your network is properly segmented and firewalled (a common thing we see is that although you tend to protect your network from the external entities, you rarely practice segmentation internally. Hence, when a network gets compromised, it is easy for the attacker to travel within your network), monitor suspicious usage of privileged accounts and limit what privileged accounts could do in your network.

The next step of the attack would be to make themselves Persistent in your environment. Many attackers put in a lot of effort to gain access to your network and the effort is mostly proportional to the amount of security you maintain on the network. Once this is done, the attacker would hate to lose access via a reboot or change of credentials or other interruptions. Hence, they deploy methods such as using the group policy feature of windows environments, registering as a service, creating scheduled tasks, and creating new accounts to make sure they will not lose their control abruptly. A few methods of detecting and preventing such attempts would be to limit what actions user accounts can perform, monitoring suspicious user creations (e.g. users created during off hours) and monitoring group policy or other services related changes.

Before moving to the final stage of the attack, attackers may opt to steal your data – Data Theft. This isn’t a very common move, but we have witnessed some instances. If attackers sense that your data would have a substantial black-market value or that your brand image would be gravely damaged by certain information becoming public, then they would decide to exfiltrate your data. A common method of stealing data could be uploading the files to a file share site (it’s very common for administrators to allow file sharing sites to make their day-to-day work easy but keep in mind attackers too could exploit these same paths). The methods of preventing or minimizing such data loss would be to implement Rights Management Systems (this will help you to make sure that even if the data is exfiltrated the attacker cannot use it), implementing Data Loss Prevention Systems (will detect/prevent when data is been exfiltrated) and block file sharing sites that aren’t needed for work-related matters.

The final step of the attack would be Payload Detonation. Unfortunately, it’s at this stage most organizations learn that they have been attacked, and by the time the initial panic phase has passed, a lot of damage might have been done already.

There are two types of payloads that we have come across – Cryptominer and Ransomware. Cryptominers do not exhibit any visible damages on your machines and would rather utilize your resources such as CPU and RAM to perform crypto currency mining. In such a situation, you will notice heating up, slow performance, huge bills for your cloud consumption, and abrupt crashing of your devices.

Ransomware is the more devastating type of payloads we see. It will start encrypting the commonly used file types, such as documents, videos and photos, and at the end, it will display a note stating what the attackers have done, laying out their demands, what will happen if you do not comply, and in case you want to comply how the money should be transferred. Attackers use crypto currency as the medium of paying ransoms as this method is more difficult or impossible to trace. Once the ransomware is detonated, it could effectively bring down your entire IT infrastructure. It could encrypt the end user devices as well as the servers that host your critical systems, such as application servers, database servers and email servers. In case the attacker has stolen your data, this is the stage where they will communicate to you about the ransom you need to pay to prevent the data from being released to the Internet. They would even go ahead and share a sample of the stolen data to make sure you know they’re serious.

Reputational Damage Is Far Worse Than Data Leaks

Many organizations do not opt to pay (or cannot afford to pay to recover everything that has been encrypted). Hence, they resort to restoring their systems from scratch, which takes a lot of time and effort. This, in turn, results in massive delays before the organization can get back online to serve their customers. Although the most visible damage of these attacks is done to the IT infrastructure, the biggest, unforeseen damages are to the brand identities of these organizations. News travels fast and bad news will travel even faster. No organization will ever want their names associated with such an event, and any negative media coverage and reputational damage could be made far worse by releasing your confidential data to the public domain.

A pertinent question customers ask during the final stage of an attack is “Why can’t my signature-based antivirus software detect this malicious file (payload)?” The answer is that in many scenarios, attackers change the signature (hash) of the payload before using it during the attack. Many legacy antivirus software solely depend on signature updates, and if the signature isn’t in the database, it is very easy for the attacker to bypass the antivirus tool.

Quick Detection, Quick Response and Strong Recovery Plan

Many organizations take a long time to detect such attacks. And when they do, it is sadly at the final stage of an attack. One main reason for this is that most customers utilize legacy detection mechanisms that have a very narrow visibility instead of adopting more current detection mechanisms which have a broader, in-depth view of the environment.

Based on our recent experiences and observations, many organizations take a long time to get their critical business services up and running or in other words, they take considerable amount of time to execute their business continuity plan (BCP). Moreover, although many organizations have satisfactory BCPs and DRPs (Disaster Recovery Plan) in place, almost all of them are rendered little or no use to safeguard from these attacks. Most of these plans have been formulated to protect organizations against events such as natural disasters, power failures, terrorist threats, assuming the backups will be available to start their recovery. Attackers generally know this and will start by targeting the backup systems as the initial attack points before moving toward other critical assets. This way the attackers know they can force the victim to pay up since they have no other means of recovering.

Another interesting fact about these attacks is that most of the activities happen either during early hours or during holidays. The main reason is that attackers try to leverage human weaknesses (even security operations centers are less alert during these times) to their advantage.

In summary, based on our observations, we can no longer consider Sri Lanka as a country with a very slim chance of being attacked. And these attackers seem to always find enough ways to circumvent defenses employed by most organizations and continue undetected till the very last stage. Many organizations need to rethink and plan their BCPs and DRPs to safeguard from ransomware attacks.

In the past, organizations believed in the concept of “Survival of the Strongest,” i.e. if you keep increasing your defenses, you can prevent any cyber-attack. But now, we believe organizations need to equally focus on the concept of “Survival of the Fastest,” which means it is inevitable that your organization will be targeted by an attacker sooner or later, and when that time comes, what matters is how fast you can detect, contain and recover. In other words, the speed at which you react to contain and recover from such an attack will define how your organization will withstand such an event.

MillenniumIT ESP: Your Complete Enterprise Solutions Provider

MillenniumIT ESP: Your Complete Enterprise Solutions Provider

MillenniumIT ESP (MIT ESP) turned 25 in January this year. Having joined the company just a few months prior as CEO, I had the opportunity to reflect on the company’s journey over the past two and a half decades along with the team. It was an inspirational and insightful exercise that highlighted the work done so far in terms of achievements by the MIT ESP team and what it was capable of doing in the future as well. Many transformational, turnkey technology projects had been successfully executed and delivered, changing not only the business landscape of our customers but also, in some instances, positively impacting the technology landscape in Sri Lanka. Over 500 customers across all industry sectors have seen MIT ESP in action through the delivery of an estimated 2,000+ projects, both locally and internationally. The trust and confidence gained has resulted in many customers continuing to work with us, some even for as long as 25 years!

The core that has held everything together to make this happen has been the 1,000+ people who have walked the floors of MIT ESP at some point in their careers. The company currently employs 400+ people with more than 60 people who have served for more than 10 years, and nearly 10 of them for more than 20 years. This is a valuable amount of experience retained in the company, mostly attributed to the culture and environment that the team has cherished and nurtured for decades. This also means that the current team possesses an incredible amount of knowledge and experience gathered from successful projects as well as important lessons from the challenging ones.

MIT ESP is widely known as one of the oldest, largest and premier Systems Integrators in Sri Lanka. However, over the years, with the accumulation of knowledge, skills and experience gained, the company now goes far beyond that of a typical Systems Integrator. This evolution prompted us to take a step back and consider how we Reimagine and Reinvent ourselves, staying true to our tagline which has done just that for our customers for years. We spent several months as a team brainstorming on what we are good at, the knowledge and skills we want to build to be competitive in the future and what is needed for us to be competitive globally as well. Bringing it all together, we felt that we needed to refresh our positioning from being a ‘Systems Integrator’ to a ‘Complete Enterprise Solutions Provider.’ In order to effectively deliver on this positioning, we have repackaged our business and restructured ourselves to ensure we focus on the relevant technologies that make us a Complete Enterprise Solutions Provider.

Expertise in Core Infrastructure has been the mainstay of the company through the experience gained as a Systems Integrator. Our Core Infrastructure unit will continue to ensure our customers are provided with optimum infrastructure solutions at optimal cost and will deliver, deploy and support everything to do with compute, networks, storage, data centers, database, middleware, etc.

Our Intelligent Automation and Data unit focuses on providing solutions based on Robotic Process Automation (RPA), Artificial Intelligence, Machine Learning, etc. to improve overall productivity and efficiency. We combine our approach to automation with our expertise in IoT and sensors and Data to create a powerful proposition of optimizing enterprise data architecture, correlating data across systems, enabling intelligent automation of workflows, and providing better insights that ensure enterprises are enabled for data-driven decision making.

Technology has had a significant impact on new constructions where buildings, offices and cities are increasingly becoming ‘Smart’. Our focus on Smart Buildings is geared towards setting up the technology infrastructure required to make buildings smart, including structured cabling, access points, telephony, and other sensor-based components. Our expertise also extends into providing building management solutions, parking management, security and surveillance, and other technologies that optimize building operations.

Managed Services bring it all together where our fully fledged Network Operations Center (NOC) and Security Operations Center (SOC) are able to take away operational overhead of managing applications, storage, databases, security, networks or even entire IT operations based on industry best practices and standards while also providing significant cost savings. This is a proven capability with state-of-the-art facilities that remotely manage IT for many global customers.

In order to provide the above capabilities, we continue to leverage our long-standing partnerships with industry leading technology providers – a pool that has now grown to nearly a hundred. Some of the partnerships extend over two decades and have given us the opportunity to elevate our expertise and status to a level second to none in the region, resulting in the capability to deliver best-in-class solutions to our customers. We also combine this with a Customer Success based approach to delivery where we deploy an engagement model that brings in learnings from 25 years of delivering large, complex projects in order to ensure on-time delivery, quality, customer satisfaction, and commercial assurance.

As CEO of MIT ESP, I take this opportunity to thank all customers, partners and our own team for what the company has achieved over the last two and a half decades. We now look forward to supporting our customers in bigger and better ways as a Complete Enterprise Solutions Provider!

Working from Home: Tips & Bytes

Working from Home: Tips & Bytes

If correctly done, you can be more productive and focused. Some tips based on my experience as I have done this quite often over the last 10-15 years during my short work from home overseas stints…

Daily work routine
  1. Mindset – It is important that you place yourself in a work mindset than a lazy holiday mindset. Wake up in the morning on the same basis as you would be doing on a normal office day and get on with the routine, only difference is that you have additional time due to no travelling requirement. You can use this time either to sleep or do your personal work. I do the latter as that way when things are back to normal your biological clock is ready.
  2. Have a separate place/table for your computer/devices and books. That helps focus and be in that mindset. Your children could do the same.
  3. Attire helps. If you are with the PJ’s, the mindset will not change. Wash and change clothes (not office attire but fresh casuals), thus you are ready to kick off.
  4. Take water breaks and tea breaks but work on a table at least for a couple of hours at a time.
  5. Remember, the concept is that you have only changed the physical working location.Work has not changed nor should your attitude towards work change. You are expected to be fully available during working hours.
Other activities – (Social/Casual)

If you have extra time at home, latch onto something interesting. Make sure your children do the same. There are hundreds you can select from but make them useful as much as possible. Time is money. Here are some options from my own personal experience:

  1. Enroll with web-based education. ‘Udemy’ is an example. Take a small course on whatever you like. It can be even a new language or playing an instrument or meditating. These are not very expensive.
  2. Complete that personal note/journal that you always wanted to do.
  3. Make that picture album from existing pictures in your hard drive.
  4. Clean up your inbox, which otherwise usually is cluttered.
  5. One-hour home lessons on ‘values’ for kids. We hardly spend time on this.
  6. Decluttering techniques for home and office.
  1. Sleeping throughout the day or more than required.
  2. Online videos/films and games.
  3. Minimise social media. This could be a killer.
  4. Minimise travel these days. Practice social distancing for greater good of mankind.
Have fun and work smart!

In Search of Sri Lankan Unicorns

In Search of Sri Lankan Unicorns

Here’s a Billion Dollar question!

Who is going to be the first Sri Lankan Unicorn? The first Sri Lankan startup with a billion-dollar valuation?

How many Unicorns can Sri Lanka produce in the next five years?

Merely asking that question changed my perception, from an “If” to a “Who” and a matter of time.

In the last five years, twenty more countries have joined the Unicorn Club. These include countries such as Indonesia, Colombia, Philippines, Estonia & even tiny countries like Malta.

Our next-door neighbour, India now has 19 unicorns with 5 more awaiting to be added to the list within the year 2019. By the end of this year, India will dislodge United Kingdom to claim the third spot in this prestigious club.

So, “Why not Sri Lanka?”

“Are we not a nation rich in intellectual capital?”

“Are we not a nation rich in creative capital?”

“We are the island of ingenuity!”

“We should be on that list!”

To understand the current context better, let’s look at some trends!

There is a proliferation of Unicorns around the world. Unicorn population is growing, and their birth rate is increasing.

In 2011 only 4 companies attained Unicorn status, but in 2018, 79 Unicorns were born. By Q3 of 2019, 76 companies have attained unicorn status. It is expected to cross 90 by the end of 2019

Unicorns are getting younger! Their average age has reduced from 40 months in 2011 to 20 months by 2018.

What is fueling this rapid proliferation and acceleration?

What is happening around us?

Are we actually in the midst of a revolution, the 4th Industrial Revolution?

In my view, it’s a little too early to be 100% certain. Usually, a revolution becomes a revolution when the revolution is over, when we see irreversible changes in the social, political and economic fabric around us.

But there are glimpses of credible evidence leading us think that we most probably are. Here’s why!

Any revolution, be it industrial or otherwise, has three key elements.

The disruptors that can challenge the status quo;

The ideology that draws masses into subscription;

And finally, the outcomes that change the social, political and economic fabric around us, permanently.

Currently, we clearly see three waves of disruptions!

The wave of Analytics which started around 2010, has already peaked.

The second wave, Augmentics is rising and it will crest within the next decade. Augmentics are technologies that enhance human capabilities; such as Computer Vision, Natural Language Processing, AI and Brain-Computer-Interface.

The third wave of Autonomics is just emerging. Autonomics are technologies that make machines self-sustaining, self-governing; Self-driving cars are just the start.

We envisage these disruptions to take place over the next 25 to 30 years.

If we are convinced that we are amidst a revolution, here’s another intriguing question!

“What are we revolting against, and Why?”

This leads us to the ideology which is fueling the revolution.

The past industrial revolutions, among many other ideologies, had one in common. This is the utopian ideology of liberating humans from labour; work less and live more.

liberating humans from both physical and mental labour is an underlying ideology of the fourth revolution as well. But this time around we see three libertarian ideologies taking over and spreading across the world.

For libertarians of the world, concentration of economic, political and military power are the sources of all evil.

They foresee a just and equitable world through decentralization.

Our value chains are infested with intermediaries, taking the lions share out of them, which fuels the call for dis-intermediation.

The ideology of true democratization is gaining momentum around the world to give choice back to everyone in everything we do.

The long-term outcomes of the 4th industrial revolution are too early to predict, but we can see three key aspects of our lives are changing; Work, Wealth and Wellness.

Work will change drastically in the future, not only the type of work humans will do, but also how much work humans will do.

We see countries and companies trialing out 32-hour work weeks at present.

But, 30-hour work weeks will be the norm of the future, across the globe.

The wealth of the world is changing. This is mainly due to fact that the assets that we leverage to create wealth are changing.

We see three new asset classes emerging; Data & Insights, Community & Influence and Collective Intelligence.

All exponential growth companies leverage at least one class of these assets, even at present.

Finally, the very meaning of wellness is changing. Advances in healthcare, new thinking in welfare, leisure redefined by digital experiences, convenience brought to us by technology are elevating our quality of life.

Everything we discussed so far present us with both challenges and opportunities. The opportunities are immense as these are the times the status-quo is challenged.

These are the times the rules are broken, and the new ones are re-written.

These are the times an unfair advantage awaits the bold.

These are the times countries like Sri Lanka can gain that unfair advantage.

Isn’t this the most opportune time in our lifetime to put Sri Lanka back on the world map?

So, how do we capitalize on these transformations and disruptions?

We don’t have a crystal ball to see the future, but we should be ready to capitalize on any challenge thrown at us.

We need to be agile to respond to the rapid changes in technology, markets, consumer behavior and everything else around us.

We need to be creative to find answers to humanity’s toughest problems.

Here’s why we at MillenniumIT ESP are transforming ourselves to be an Agile Creator!

So, how can we be a part of this exciting journey?

At present a vibrant startup Eco-system is emerging in Sri Lanka. A lot of companies, industry bodies and angel investors have come to fore to create this.

But we see a considerable void; lack of adequate support for startups beyond seed stage.

We want to join hands with the existing incubators, accelerators and angel investors to elevate Sri Lankan startups to the next level.

Our proposition is not only to provide next level of funding but also to provide market access and technology.

Over the last 25 years MillenniumIT ESP has built credible relationships and robust channels in many markets. We want to partner with you to carry your products and co-sell.

We are also bringing Technology Providers, Knowledge creators and communities together to build skills and competencies in technologies of the future, such as Machine Learning, Data Science, Cognitive computing and IOT. We want to partner with you for technology to co-build your products.

We invite everyone to join hands to co-build, co-sell and co-own and elevate Sri Lankan startups to the global scale.

Now, let’s ask ourselves that Billion Dollar question again!

Who is going to be the first Sri Lankan Unicorn?

It is us!

It’s here!

And the time, is now!

Here’s to us, the future unicorns!
