The Dark Side of Ransomware Attacks

The Dark Truth Behind Ransomware


Ransomware attacks have become an alarming threat in our increasingly digital world. As cybercriminals employ sophisticated techniques to exploit vulnerabilities, the consequences are felt by individuals, businesses, and even entire nations. In this blog post, we will delve into the dark side of today’s ransomware attacks, exploring the alarming trends and consequences that accompany these malicious acts.


The Rising Sophistication of Ransomware Attacks


Over time, ransomware attacks have evolved into more intricate and advanced operations. Cybercriminals now employ sophisticated tactics to maximize their impact. Spear-phishing, where attackers carefully craft personalized emails to trick victims into revealing sensitive information or downloading malware, has become a prevalent method. Additionally, zero-day exploits, which target software vulnerabilities unknown to the vendor, provide attackers with an advantage. Encryption algorithms used by ransomware have also become increasingly complex, making it extremely challenging for victims to recover their data without paying a hefty ransom. The complexity and ever-evolving nature of these attacks have made them a formidable menace.


Devastating Impact on Individuals and Businesses


The consequences of ransomware attacks are devastating for both individuals and businesses. Personal files, sensitive data, and intellectual property can be irreversibly encrypted or stolen, leading to significant financial losses and emotional distress for individuals. Businesses, on the other hand, face even more severe repercussions. Operational disruptions caused by ransomware attacks can halt critical processes, leading to significant financial losses. Moreover, the reputational damage resulting from an attack can have long-lasting effects, causing a loss of customer trust and potential bankruptcy.


Here are some notable examples of destructive ransomware strains witnessed in recent years:


CryptoLocker (2013): CryptoLocker emerged in September 2013 and caused widespread havoc until its neutralization in May 2014 by an international cybersecurity task force. Its propagation was facilitated through the extensive Gameover ZeuS botnet.



Petya (2016) & NotPetya (2017): The Petya ransomware family first emerged in 2016, but it was the devastating NotPetya strain that garnered widespread attention in 2017. NotPetya caused more than $10 billion in damages across Europe and the US.


WannaCry (2017): In May 2017, the WannaCry ransomware launched a highly impactful attack, infecting over 230,000 computers in 150 countries within a single day. The resulting damage and cleanup expenses were estimated to reach $4 billion.


DarkSide (2020): DarkSide gained notoriety in 2020 and 2021 for their RaaS model, which resulted in significant ransomware attacks and extortion demands. Although they claimed to avoid targeting government and healthcare entities, the group was responsible for the 2021 Colonial Pipeline attack, which disrupted fuel supplies across the US East Coast.


Nvidia (2022): In 2022, Nvidia, the semiconductor giant, was hit by a ransomware attack. Employee credentials and data were leaked online. The hacking group Lapsus$ claimed responsibility, demanding a $1 million ransom and a percentage of fees.


By highlighting these significant instances of ransomware, it becomes evident that this form of cyber threat has evolved over time, growing in complexity and impact.


Targeting Critical Infrastructure


The dark side of ransomware attacks extends beyond individual targets to critical infrastructure. In recent years, cybercriminals have shown an increased interest in targeting hospitals, energy grids, transportation systems, and government institutions. The motivation behind these attacks is not only to compromise sensitive data but also to put lives at risk and disrupt essential services. The consequences of successful attacks on critical infrastructure can be dire, underscoring the urgent need for robust cybersecurity measures to protect these vital systems.


Ransomware as a Service (RaaS)


The advent of ransomware-as-a-service has further exacerbated the threat landscape. Cybercriminals now offer ready-to-use ransomware kits to aspiring attackers, enabling them to execute sophisticated attacks without advanced technical skills. This commodification of ransomware has significantly contributed to its widespread proliferation and increased the number of potential attackers. The availability of RaaS lowers the entry barrier for cybercriminals and poses a challenge for law enforcement agencies and cybersecurity professionals.


Evolving Payment Methods and Cryptocurrencies


To facilitate ransom payments while maintaining anonymity, cybercriminals have turned to cryptocurrencies like Bitcoin. These decentralized digital currencies allow transactions to occur without being easily traceable. The use of cryptocurrencies complicates law enforcement efforts, as traditional financial institutions have limited visibility into these transactions. The relative anonymity offered by cryptocurrencies enables cybercriminals to operate with a reduced risk of detection and apprehension, adding to the challenges faced by authorities in combating ransomware attacks.


Collateral Damage and Hidden Costs


Beyond the immediate impact of ransomware attacks, there are hidden costs and collateral damage that organizations must face. The financial burden associated with incident response, recovery efforts, and potential legal actions can be significant. Furthermore, the loss of customer trust and diminished market reputation can have long-lasting effects on businesses, amplifying the damage caused by these attacks. Rebuilding trust and restoring operations after an attack can be a lengthy and costly process.


Urgent Need for Cybersecurity Collaboration and Proactive Measures


Today’s sophisticated ransomware attacks pose a severe and escalating threat to individuals, businesses, and critical infrastructure. The dark side of these attacks encompasses the rising sophistication of techniques, the devastating impact on victims, the targeting of critical infrastructure, the accessibility of ransomware-as-a-service, the use of cryptocurrencies, and the hidden costs incurred. To mitigate this menace, it is crucial to prioritize cybersecurity measures, stay informed about emerging threats, and foster collaborations to combat this growing cyber threat landscape. Proactive measures such as regular software updates, employee training on cybersecurity best practices, and robust incident response plans are essential for organizations to defend against these ever-evolving ransomware attacks. By working together, we can make significant strides in protecting ourselves and our digital assets from the dark side of ransomware attacks.

November Security Breach Round Up

November Security Breaches

From grocery stores, to banks, and everything in between – November saw it all when it came to breaches. As I mentioned in September, hackers are not picky. Let’s just say, when an opportunity arises, they will swoop right in and overtake your systems and access any data they can get their e-hands on.

 

Be careful, and keep staying informed – our goal is to make sure no company ends up on this list next month. 

 

Let’s dive in. 

 

  1. WhatsApp


Whatsapp with this?! The app that we all know, love, and use, WhatsApp, has supposedly fallen victim to a massive data leak. And by massive, I mean nearly 500 million user records have been leaked online. So… what happened? On November 16, 2022, an ad on a well-known hacking community forum was posted by someone claiming to be selling a 2022 database of WhatsApp user mobile numbers. It is also claimed that 32 million users from the United States have been included. Although only phone numbers were leaked, it is important to note that leaked phone numbers are typically used for marketing purposes, phishing, impersonation, and fraud. 

 

  1. Bed Bath & Beyond

Ah, phishing at its finest. While almost anyone who enters Bed Bath & Beyond can get lost for hours browsing, no one likes hearing about breached data. The United States retail giant confirmed that unauthorized access to company data was accessed after an employee was phished. In an 8-K filing to the U.S Securities and Exchange Commission, Bed Bath & Beyond explained that data of the employee’s hard drive and other shared drives that the employee had access to were accessed. The company is still investigating whether the drives have any sensitive or personally identifiable information.

 

  1. DropBox


File hosting service, DropBox, also fell victim to a phishing incident. In a statement from the company, they explained the situation saying “We were recently the target of a phishing campaign that successfully accessed some of the code we store in GitHub. No one’s content, passwords, or payment information was accessed, and the issue was quickly resolved. Our core apps and infrastructure were also unaffected, as access to this code is even more limited and strictly controlled. We believe the risk to customers is minimal. Because we take our commitment to security, privacy, and transparency seriously, we have notified those affected.” The company goes on to explain that on October 14, GitHub alerted them that suspicious behavior was going on. DropBox found that a threat actor was pretending to be CircleCI and was able to access one of DropBox’s GitHub accounts. To date, their investigation has found that the code accessed by the threat actor contained some credentials, primarily, API keys used by Dropbox developers.

 

  1. TransUnion


Isn’t it ironic how an agency who determines your credit score, is the one that could be ruining your credit? There are three main credit bureaus in America – Experian, Equifax and TransUnion. Unfortunately, the consumer credit reporting agency, TransUnion, experienced a breach and began notifying individuals about the incident on November 7,2022. The company collects and assembles information on over 1 billion consumers worldwide, 200 million of those being Americans. The type of information that was exposed includes names, social security numbers, driver’s license numbers, and account numbers. 

 

  1. AirAsia


AirAsia, the largest airline in Malaysia with approximately 22,000 employees and worldwide operations, has unfortunately fallen victim to a supposed ransomware attack. The group behind this attack is known as the Daixin Ransomware Gang and they have supposedly stolen data of 5 million AirAsia passengers and employees. The Daixin team is known for disrupting operations with ransomware and stealing personally identifiable information. With this data, the cyber threat group threatens to release the stolen information unless a ransom is paid. In a tweet shared by Soufiane Tahiri, screenshots from the group can be seen that were posted on the dark web. The information applies to both employees and passengers. In these documents, information such as date of birth, country of birth, where the person is from, start of employment for employees and their secret question and answer used to secure their accounts could be found. 

 

  1. Sonder


In a company security update, Sonder, a hospitality company, notified the public that they became aware of unauthorized access to one of its systems that included guest records. Information that was accessed includes: 

  • Sonder.com username and encrypted password

  • Full name, phone number, date of birth, address, and email address

  • Certain guest transaction receipts, including the last 4 digits of credit card numbers and transaction amounts

  • Dates booked for stays at a Sonder property

  • Government issued identification such as driver’s licenses or passports

 

  1. Sobeys

This incident shows that ANY business can get breached. Even a supermarket. Incase you aren’t familiar, Sobeys is one of the two national grocery retailers in Canada. On November 7, 2022, Sobeys’ parent company wrote in a notice that the grocery stores were impacted by an IT systems issue. While the company hasn’t publicly confirmed a cyber attack on its systems, a local media outlet reported that “two provincial privacy watchdogs said they had received data breach reports from Sobeys. Both Quebec’s access to information commission and Alberta’s privacy commission have both been notified by the grocer about a “confidentiality incident.” 

 

  1. Whoosh

Russian scooter sharing company known as Whoosh has confirmed that it too was breached. Hackers started to sell a database containing the details of 7.2 million customers on a hacking forum. Alleged stolen data on the hacking forum allegedly contains promotion codes that would allow someone to access the service for free, as well as partial user identification and payment card data. Included were email addresses, phone numbers, and first names. A russian news outlet, RIA Novosti was told by Whoosh that, “The leak of some of the personal data of customers of the Russian scooter rental service Whoosh at the beginning of November did indeed occur, but did not affect sensitive user data, such as access to accounts, transaction information or travel details” 

 

  1. Coinsquare:


Cryptocurrency is a sexy industry to talk about, but this incident is a little less appealing. To round up the month, a Canadian cryptocurrency exchange, Coinsquare has become the latest victim of a security breach. Data such as customer names, email addresses, residential addresses, phone numbers, dates of birth, device IDs, public wallet addresses, transaction history, and account balances were compromised. According to customer reports, Coinsquare allegedly contacted them via email and let them know that it had identified an intrusion and a database containing personal information accessed by an unintended third party. In a Tweet responding to an account sharing about the hack, Coinsquare wrote, “We have no evidence any of this information was viewed by the bad actor, but in an abundance of caution, we wanted to make our users aware. We notified all clients, but only identified 3 clients whose accounts were accessed.”
