The State of Ransomware: From Evolution to Progression

The State of Ransomware

CISO MAG, in association with Cybereason, conducted a virtual round table discussion on “The State of Ransomware”.

The panel discussed the evolution and the new trends in ransomware attacks. Grab the snippet of the discussion below…

Since the past decade, ransomware has been one of the most common types of malware deployed during a cyberattack. However, if anyone asked to place a finger on a year that marked the sudden surge of ransomware, it would be 2020.

As per a recent report,  in the past year (from H2 2019 to H1 2020), there have been more than 500 successful ransomware attacks in over 45 countries that were reported officially. This means every single day there has been more than one ransomware attack around the globe. Experts believe this number could even double if all attacks were reported. The financial damages arising from ransomware attacks during the time period have accounted for over $1 billion ($1,005,186,000) and the future forecast predicts this number to rise 20 times to $20 billion by 2021.

So, how do you tame the raging bull going by the name “Ransomware”? To take on the bull by its horns, CISO MAG, in association with Cybereason, conducted a virtual round table discussion on “The State of Ransomware.” The discussion was moderated by Cybereason’s Tarek Kuzbari, Regional Director Middle East & Turkey, who was joined in by Eng. Abdullah Biary, CISO at SALAMA Cooperative Insurance Co., and Hamad Al Katheri, Enterprise Risk & Information Security Vice President, Zain.

The discussion was led on the following key points:

Evolution of Ransomware

Since the turn of the century, cybercriminals started playing with human psychology and spread emails consisting of fearful or anxiety-inducing content to pressurize readers into clicking malicious links, which further installed malware. This technique was adopted by ransomware gangs, which, after installing the malware on an individual’s computer, encrypted the data and left a ransom note in exchange for the decryption key. This modus operandi worked perfectly for years but gave smaller returns to threat actors. Thus, came the next step in the evolution – targeting bigger organizations.

The State of Ransomware, Tarek Kuzbari

“Ransomware attacks have now become daily news. You pick up your paper or mobile phone and there it is, so and so company has been hit by a ransomware attack written in BOLD”

– Tarek Kuzbari, RD Middle East and Turkey, Cybereason

Answering Tarek’s questions as to why the shift towards bigger company’s and not individuals, Abdullah Biary said, “It is simple. Moving from individuals to bigger organizations gave threat actors better returns. Large corporations have critical and sensitive data, which, if leaked, could cause not just monetary but reputational damages. These are not easy to repair.” And thus, threat actors leveraged on this exact fear.

Current Trends and New Tactics

Ransomware has certainly not reached its final stage of evolution. Ransomware gangs now download critical data from the victims even before encrypting their machines. They use this data as a means to negotiate. If the victims fail to pay the ransom, they threaten them by hosting data auctions on the dark web. In fact, REvil, an infamous ransomware gang, has already staged an auction website to sell the stolen data who refuse to pay ransom. In Hamad’s words, “this is Blackmail,” and it indeed is.

Tarek also raised a very important issue of ransomware being sold “as-a-Service” (known as RaaS). Abdullah Biary agreed by saying, “Yes, this has simply taken off. They are distributing it as Ransomware-as-a-Service to earn some extra money and collaborate. They are uniting and so should we in its defense.”

Tarek asked Hamad whether there was a missing gap in ransomware that adds to our pain point, to which he replied, “Gaps are there, and they have always been there. There is nothing one can do about it other than continuously monitoring and fixing these gaps proactively.”

Lessons from the Field

Humans and Technology

Time and again it has been said that humans are a weak link, and the panelists echoed this thought. Hamad said, “The human factor in security is the most dreaded. Small mistakes like delayed patching or updating the systems and application cause the reason for exploitation.” Abdullah seconded Hamad by saying, “More than technologies like the XDR and MDR, organizations need rightly-skilled cybersecurity workforce. This is the need of the hour.”

“More than technologies like the XDR and MDR, organizations need rightly skilled cybersecurity workforce. This is the need of the hour. Humans can make or break security.”

To Pay or Not to Pay, That is the Question

The U.S. Department of the Treasury (OFAC) recently announced that paying ransom to cybercriminals is now illegal. Governing bodies around the globe have always condemned ransom payments, but this is the first instance where it has actually been documented that paying up a ransom is illegal. Thus, taking the discussion forward, Abdullah said, “We should not, but it is situational.” Giving the example of the recent death of a person due to delayed medical aid since the hospital was hit by a ransomware attack, he said, “This is an exception. It’s a matter of life and death and nothing comes above saving a life.”

Hamad had similar views and said, “This should be the last resort. If you pay then you are a potential customer to the bad guys, they will come back to you. Also, there is no guarantee of getting your data back. So, why pay? However, this is always a difficult choice, to pay or not to pay.”

How to Better Protect Your Organization from Ransomware

As stated earlier, we are far from the end of the tunnel of ransomware attacks. They are only beginning to fizzle up. Probably, the worst is yet to come. So, how do we strengthen our defenses against a ransomware attack? Tarek asked this question to both panelists and they gave our participants some good insights.

Abdullah said, “Constant monitoring along with frequent penetration testing and vulnerability assessment is utmost important.” Additionally, he also recommended one more thing that he asks his own team to follow – “keeping track of all assets.” He suggests, “With accountability of all assets of internal teams, you know what you need to defend and be ready for an attack at all instances.”

Adding to this, Hamad suggested the adoption of a proactive approach. “Do not wait until it happens. Defend as if it is definitely going to happen.” He reminded the participants of the popular cybersecurity adage, “A good guy (defense) needs to be right all the time, but a bad actor (offense) needs to get it right just once.”

Hamad Faisal Alkatheri, The State of Ransomware

“Your data is a crowned jewel. Always encrypt it, else it will be bad very bad.”

– Hamad Al Katheri, Enterprise Risk & Information Security VP, Zain

 

Lastly, Tarek asked our panelists to pick the top three pieces of advice that could be the crown jewels for the fight against ransomware attacks, to which both unanimously agreed upon the following:

  1. Identify your assets: Understand what needs to be protected based on the risk analysis reports from the internal teams. And as Hamad said, “Your organization’s data is a crown jewel. Always Encrypt it.”
  2. Define critical business flows: Gather as much information as possible. You need to ask all stakeholders to submit what they believe is most critical to the business flow. Every team has a different perspective. So, considering every perspective will help you design a better guideline for security.
  3. Convey and convince the business leadership: This step is very important. Return on investment (ROI) is something that business leaders are always interested in. Explaining to them why investing in protection against a cyberattack, which might or might not take place, could be tricky. Abdullah suggested, “Talk to them in their own language. Show them numbers and make them understand the importance of investing in cybersecurity.” Hamad added, “There is no room for regret in cybersecurity. Investing the money once you are already attacked does not make sense. Do it when there is still hope.”

The virtual round table was attended by nearly 100+ participants and the insightful discussion kept them glued to their screens throughout. CISO MAG would like to take the opportunity to once again thank Mr. Tarek Kuzbari, Eng. Abdullah Biary, and Hamad Al Katheri for their valuable time and meaningful insights on “The State of Ransomware.”

Sophos Suffers Data Breach; Small Subset of Customers Impacted

DEO data breach

Cybersecurity firm Sophos is the latest victim of a data breach that affected a small subset of its customers’ information. The exposed information included customer details like first and last names, email addresses, and phone numbers if provided. The data breach incident came to light after a security researcher reported the issue to Sophos.

“On November 24, 2020, Sophos was advised of an access permission issue in a tool used to store information on customers who have contacted Sophos Support. Only a small subset of the customers was affected, it added. At Sophos, customer privacy and security are always our top priority. We are contacting all affected customers. Additionally, we are implementing additional measures to ensure access permission settings are continuously secure,” as per Sophos breach notification.

Prioritizing customer privacy and security, Sophos notified the impacted users via email. The company develops security products for communication endpoints, encryption, network security, email security, mobile security, and unified threat management. The company is primarily focused on providing security software solutions to mid-market businesses.

Recently, Sophos partnered with Mapua, a Philippines-based technology university, to offer cybersecurity courses and training to university students. The new training alliance comes on the heels of a skills shortage in the cybersecurity sector and frequent data breaches in recent years. The partnership intends to enhance students’ skills and knowledge of cybersecurity. With the latest partnership, Sophos will offer train-the-trainer-style education on XG Firewall, which would earn Mapua faculty members the certification to teach the courses and embed these into the university curriculum. It also provides an option for students to obtain certifications from Sophos through an examination.

5 in 10 Ransomware Attacks in 2020 Occurred in the U.S.

Ransomware, supply chain and ransomware

Organizations in the U.S. witnessed a greater number of ransomware attacks than any other country, research from security firm BlackFog revealed. According to the research report, “The State of Ransomware in 2020,” nearly 57% of all ransomware attacks tracked in 2020 were reported in the U.S., with cybercriminals demanding $176,000 ransom per victim. It is found that ransomware operators focused mostly on organizations that are having tens of thousands of employees.

Key Findings

  • Australia stood second with 7% of ransomware attacks, followed by Canada (6%), the U.K. (5%), and Germany (4%).
  • The public sector was the primary target in 2020, with 34% of attacks, followed by education (29%), manufacturing (33%), health care (24%), and general services (23%).
  • In the Q4 of 2019, ransomware victims paid over $45,000 to threat actors. While in Q2 2020, victims paid up to $180,000 on average.
  • Most of the attacks were operated by infamous hacker groups like Maze (17%), REvil/Sodinokibi (16%), NetWalker (14%), and Ryuk (13%), making 60% of ransomware attacks globally.
  • The average ransom demand for a Maze attack is $420,000, Ryuk ransomware operators demand $282,590 on average, and the NetWalker group demands $176,910.
  • Ransomware actors targeted organizations that are having an average of 37,000 or more employees.

BlackFog predicts that an organization is attacked by a cybercriminal every 11 seconds and the damage costs from these attacks will hit around $20 billion by 2021.

Ransomware: A Lucrative Business

A recent survey from the Financial Services Information Sharing and Analysis Center (FS-ISAC), highlighted that rapidly evolving ransomware attacks have become a primary security concern for most financial organizations. The research indicated that ransomware operators have openly claimed successful attacks against eight financial institutions globally in 2020, three of which were banks. The FS-ISAC suggested that even organizations with robust cybersecurity defenses are still vulnerable to ransomware threats, especially through their third-party providers. Read the full story here…

Beware! Online Stores Susceptible to BEAST SSL Attacks

online shopping, International Fraud Awareness Week

A new security analysis from CyberNews revealed that many popular online stores are vulnerable to SSL vulnerability that could allow threat actors to exploit and steal sensitive information. In an official statement, CyberNews stated that it analyzed web servers of 2,620 popular e-commerce domains for SSL configuration security and their exposure toward known vulnerabilities related to the Secure Sockets Layer (SSL) encryption protocol.

“When performing our SSL configuration analysis, we also tested the online shopping servers for six known SSL vulnerabilities, including BEAST, POODLE, and DROWN, which might allow cybercriminals to carry out SSL-based attacks against the online shops and their users. We decided to test for those vulnerabilities in particular because they are well-known, have been discovered long ago, and already have patches released for them, putting the responsibility for the existence of such security holes squarely server-side,” the researchers said.

The BEAST Vulnerability

Despite most of the shopping servers having strong SSL configurations, one-third of the web servers are susceptible to the BEAST vulnerability (Browser Exploit Against SSL/TLS). The BEAST vulnerability could allow an attacker to access the information exchanged between a web server and the user’s web browser, including shoppers’ authentication tokens, payment details, and other personal information.

CyberNews recommended users to be vigilant while shopping online ahead of Black Friday and Cyber Monday.

Online Safety

To stay safe while shopping online, it is advised to employ multi-factor authentication to double-check the authenticity of digital users and add an additional layer of security to protect personal data and information. Browse with caution and be vigilant on what you are clicking, as it may be malware or phishing links.

Endpoint Security is a Lot More Than Just Technology: Gartner

Endpoint security goes beyond technology and requires a mindset change, says Prateek Bhajanka, Senior Principal Analyst, Gartner. He says CISOs and Security leaders must be able to respond to an attack in a timely manner, and not focus only on prevention.

Speaking to CISO MAG, Prateek Bhajanka, Senior Principal Analyst, Gartner explains why endpoints have suddenly become so important in the realm of enterprise network security.

By Brian Pereira, Principal Editor, CISO MAG

Edited Excerpts from the interview follow:

According to Gartner, there were 365 million desktops used in offices in 2019. But today, more than 1 billion employees work from home. That’s tripled the number of endpoints corporate networks. And the endpoints have moved to homes. How do you see corporates coping with the risks of attacks on home networks and remote endpoints?

As the number of endpoints increased this year, the organization became boundary-less, and there is no perimeter anymore. At the same time, the attack surface of an organization has also become wider because now, you may have one associate working from Himachal Pradesh, another working from Kerala, and someone working from Assam — or any part of the country or the world. That puts endpoint security very much on the radar or makes it one of the top priorities for any CISO or any security professional.

We see a number attacks in organizations like ransomware and phishing. The entry vector for these attacks are the endpoints. When they enter the organization’s network, they create havoc. So definitely it (endpoints) is a top priority for the organization.

To your point, what is it that the organization should be doing to make sure that they keep their endpoint segments secured? It is not just technology that would drive endpoint security, or that would be able to establish a very good endpoint security posture for an organization. It goes beyond technology. And by that I mean, the mindset needs to change at the decision-making level. It’s about the kind of awareness that needs to be created, the kind of on-ground awareness and training that needs to be imparted, to all the associates of the organization.

As we keep saying, security is a shared responsibility. Consider an organization that has a thousand employees and a thousand associates. Among these thousand associates, the level of security awareness, the level of security maturity, would vary significantly across the associates and across the employee base. And that makes it all the more harder for the organization to understand, or harder for the organizations to implement endpoint security. Ultimately, everything boils down to the understanding of the end-user or the associate. Should they click on this particular link or not, that has come from an unknown source. Whether to open this particular email or not, which may not have been solicited, or which may not be expected. So you need this kind of on-ground awareness also on top of the technology.

Can you elaborate on the mindset change?

The traditional mindset of CISOs and security leaders in India has been: let’s focus only on prevention and let’s invest only on prevention and try to stop the attacks from happening altogether. But this approach needs to change. Yes, it is changing. One should acknowledge the fact that hundred percent prevention is not possible. We must be prepared for an attack or for successful attacks. And even if we are not able to prevent an attack, we should be able to detect such an attack while it is happening. And we should be able to respond to that attack in a timely manner. To prevent it from spreading to the entire organization. So, this change in mindset, when it comes to understanding that the attacks are inevitable, it may happen. We need to have controls, we need to have capabilities on the detection and response side as well.

What about technology? We have been using anti-virus software for years to protect endpoints. Is that enough to protect remote endpoints today?

When we talk about the endpoint security technology, it is not just the anti-virus that we need anymore. We need a technology stack which can protect the organization across the layers, not just endpoint, and not just from malware, but also from phishing attacks. It should protect the endpoints from malicious websites that you may be browsing on daily basis.

The attacks that are coming from the network may result in account takeover, and credential compromised. And that’s why endpoint security goes beyond antivirus. You need a technology stack, which can help you secure against the unknown, sophisticated attacks, and which also safeguards against the email and the phishing attacks.

What are some of the attacks occurring through endpoints? Especially in India.

The most common attacks, not just in India, but across the globe, are the results of using the endpoint segment as an entry vector, to get into the organization. So if I spell out some names, it is the ransomware campaigns, the ransomware infections that we generally know about —  WannaCry, NotPetya, and other ransomware campaigns and infections.

Besides ransomware, there are phishing campaigns, spear-phishing campaigns, attacks like social engineering, and business email compromise. Data breaches result in data exfiltration and these propagate through an endpoint segment.

And as you connect the endpoint to the corporate network, these attacks spread laterally.

The easiest way for bad actors to enter an organization is through the endpoint, which could be a laptop, desktop or smart phone. An employer and associate is allowed to browse internet and visits various websites for daily business operations. The employee is allowed to check emails coming from so many different sources, from outside the organization too. They can click on various links. There could be a link to make a payment for a certain procurement. That broadens the endpoint attack surface. It also increases the number of entry points for an attacker.

Trends show that endpoint security is going to be more SaaS based. Is that why Gartner forecasts cloud security spending to increase by 250.3% in 2021?  

If you look into the definition of cloud security spending, as per the forecast report that we put out, that is more on the CASB (Cloud Access Security Broker) side. That is more due to the fact the enterprise resources are getting delivered through SaaS. It is towards securing SaaS applications like CRM, ERP, etc.

Operation Falcon: INTERPOL Nabs Three Nigerian BEC Scammers

Interpol

Based on the inputs from the threat hunting and analytics company, Group-IB, the INTERPOL conducted “Operation Falcon,” which saw three Nigerian BEC scammers getting arrested from the city of Lagos. The three alleged members belong to a larger cybercriminal group dubbed TMT. This group is popularly known to distribute malware through phishing; in other words they carry out business email compromise (BEC) attacks.

Operation Falcon, which was led by INTERPOL, had able and active support from the Nigerian Police Force and Group-IB’s APAC Cyber Investigations Team. The cybercriminals have been active since at least 2017 and have compromised more than 500,000 government and private sector companies in over 150 countries. The investigation continues as some of the gang members remain at large.

What is Business Email Compromise (BEC)?

BEC is a type of email phishing attack that employs social engineering techniques. As part of BEC, phishing emails can target people within an organization or send it to a particular group or department. It is often disguised as money transfer requests, HR-communications, or business proposals so that the cybercriminals can lay hands on confidential data.

About the Cartel

The data discovered on the devices of the arrested TMT members have confirmed their involvement in the criminal practice. The Nigerian Police Force has also identified the stolen data from at least 50,000 targeted victims.

Based on the infrastructure that the attackers use and their techniques, Group-IB was also able to establish that the gang is divided into subgroups with several individuals still at large. Researchers at Group-IB have already shared their findings on other suspected gang members with INTERPOL’s Cybercrime Directorate.

Modus Operandi

The analysis of their operations has revealed that the gang focuses on the distribution of phishing emails that contain popular malware strains under the guise of purchasing orders, product inquiries, and even COVID-19 aid impersonating legitimate companies.

The attackers then use Gammadyne Mailer and Turbo-Mailer to send out phishing emails, which are then tracked using MailChimp to see whether a recipient victim has opened the message.

Group-IB researchers note that the cybercriminals behind these BEC operations rely exclusively on a variety of publicly available Spyware and Remote Access Trojans (RATs), such as AgentTesla, Loky, AzoRult, Pony, NetWire, etc. To avoid detection and tracking by traditional security tools the gang uses public crypters. Most often malware operated by TMT communicates with the attackers’ C&C server using SMTP, FTP, HTTP protocols. 

TMT’s end goal has always been to steal authentication data from browsers, email, and FTP clients. While the monetization methods of this gang are still being investigated, it is a known fact that PII and other critical data are sold easily on the dark web, which could be the case here as well.

New Telecommunications Security Bill for U.K.

New Telecom Security Bill UK

The British Parliament has introduced the Telecommunications Security Bill to strengthen the security framework of the telecommunication companies in the U.K. The proposed legislation is intended to prevent cyberthreats from high-risk vendors by boosting the security standards of telecoms networks in the country. It also aims to level-up security standards for new high-speed fiber optic and 5G wireless networks.

The Telecommunications Security Bill gives new national security powers to the government to issue directions to public telecom providers to manage the security risks. From now, the government can impose controls on telecoms providers’ use of goods, services, or facilities supplied by high risk vendors. In addition, the telecom watchdog, Ofcom, will be allowed to monitor and assess operators’ security, and carry out technical testing, interview staff, and enter operators’ premises to view equipment and documents.

Huge Penalties

The Bill asserts that the telecoms which fail to follow the guidelines under the new legislation could face heavy fines of up to 10% of turnover or £100,000 (US$133,595) per day in case of continuing violation. “New codes of practice will demonstrate how certain providers should comply with their legal obligations. These will be published once the Bill has received Royal Assent,” the release said.

Digital Secretary Oliver Dowden said, “We are investing billions to roll out 5G and gigabit broadband across the country, but the benefits can only be realized if we have full confidence in the security and resilience of our networks. This bill will give the U.K. one of the toughest telecoms security regimes in the world and allow us to take the action necessary to protect our networks.”

NCSC Technical Director Dr. Ian Levy said, “The roll-out of 5G and gigabit broadband presents opportunities for the U.K., but as we benefit from these, we need to improve security in our national networks, and operators need to know what is expected of them. We are committed to driving up standards, and this bill imposes new telecoms security requirements, which will help operators make better risk management decisions.”

Web Application Attacks Increases 8x in H1 2020

Vulnerabilities in Zimbra

A cybersecurity report from cloud security provider CDNetworks revealed that distributed denial-of-service (DDoS), web application, and botnet attacks have surged exponentially in H1 2020 compared to the first half of 2019. In its report, “State of the Web Security for H1 2020,” CDNetworks highlighted that, in particular, web application attacks rose by 800%. Nearly 4.2 billion web application attacks were blocked in H1 2020, which is 8x higher than the same period in 2019. According to the report, DDoS attacks saw a 147.63% year-on-year increase. On average, 660 bot attack incidents were blocked every second, a number that has nearly doubled from last year. 

Public Sector Targeted

The report highlighted that cyberattacks are increasing in all sectors. Web application attacks in the public sector surged exponentially, with 1 billion web attacks reported. It was also found that cybercriminals leveraged advanced technologies like artificial intelligence and machine learning to discover and exploit new vulnerabilities across corporate networks and systems.

“The challenges of the global pandemic are leading hackers to move attacks from less visited sites, such as those related to hospitality, transportation, and other travel-related businesses, and redirect their attention to sites that are profiting under COVID-19, such as media, public services, and education. E-government and digital public service systems are also magnets to hackers due to the sensitive and valuable information these systems hold. The Report contends that attacks against the public sector will continue with increasing virulence,” the report stated.

Malicious Web Shells

Recently, the U.S. National Security Agency (NSA) and the Australian Signals Directorate (ASD) issued a joint security advisory “Cybersecurity Information Sheet” (CSI), which stated that hackers are exploiting web application vulnerabilities to deploy malicious web shells. The advisory contains a wide range of information for security teams who want to detect hidden web shells.  Read the full story here…
