RANSOMWARE THREAT "NOT IMMINENT, IT’S UPON US". Ransomware attacks have become a major concern for companies worldwide. With various attacks against things like the colonial pipeline attacks against local governments, school systems, police departments, city halls, and public schools, ransomware is everywhere in the news.
A lot of questions are created like what is ransomware, what types of ransomware exist today, how are new variants of ransomware created, who creates them, is it possible to decrypt files encrypted by ransomware, how to prevent ransomware attacks, and much newer.
These are the questions that need to be on the mind of each person in the world. Ransomware knows no boundaries. These attacks involve hackers infiltrating a company's computer network and encrypting sensitive data, rendering it inaccessible until a ransom is paid. The ransom is usually demanded in the form of cryptocurrency, making it difficult to trace and recover.
Let’s do a complete anatomy of Ransomware from its quick definition. Know your secret enemy.
Ransomware is a type of malicious software that encrypts a victim's files or data and demands payment in exchange for the decryption key. The goal of ransomware is to extort money from individuals or organizations by threatening to permanently delete or destroy the encrypted data if the ransom is not paid.
Ransomware attacks typically begin with an email or message that contains a malicious attachment or link. Once the attachment or link is opened, the ransomware begins to spread throughout the victim's computer or network, encrypting files as it goes. The victim is then presented with a message that demands payment in exchange for the decryption key.
The ransom demand is typically in the form of cryptocurrency, which makes it difficult to trace the identity of the attacker.
Each operating system has security vulnerabilities. "We are never going to find every bug but the best we can do is as we find bugs, we fix them. But these security vulnerabilities can be exploited."
There are large groups of malicious actors who are constantly scanning, looking at code, searching for these loops, and also keeping eyes to access systems. They are always looking out for a bug, and they will exploit it right then and there to make money.
They take the vulnerability in your machine and they are going to transmit some software over the internet into the machine and that software is then going to sit dormant and idle until it gets executed and so it may have a time delay of a day, a week or a month whatever but there will be some sort of a time delay between when the malicious actor accesses the machine and that code is going to encrypt a very large proportion of the files on the machine. It does not encrypt the core OS. Then it is going to pop something up on the screen like you have been hacked, your system has malware, your device is compromised, and your network has been infected.
Social engineering tactics are often used as a means to deliver ransomware attacks, which can cause significant harm to individuals and organizations.
"In 2021, the retail industry experienced the most significant increase in ransomware — 100%. Compared to 2020, the technology sector saw an 89% increase, and healthcare shot up by 30%."
"Some organizations suffered one or more ransomware attacks in 2021. Of that 76%. 42% were unintentionally caused by user actions, such as clicking on malicious links from spam emails."
"43% were due to negligence from managers or administrators (risks concerning software patches, credentials, etc.)"
"In the first half of 2022, there were 236.1 million ransomware attempts."
"Some companies choose to pay the ransom, even though it’s generally not recommended and even illegal in some countries."
Lockbit ransomware is a particularly insidious strain of malware that can leave your computer system held hostage and your important files encrypted until you pay the ransom demand. With its advanced techniques and stealthy infiltration tactics.
This type of ransomware is a force to be reckoned with in the ever-evolving landscape of cybercrime.
"In June 2021, Lockbit released version 2.0 of their RaaS, followed by version 3.0 in June 2022. The latest iteration includes new encryptors based on the BlackMatter source code, as well as new payment methods, extortion strategies, and even a ransomware bug bounty program."
Lazarus ransomware is a notorious threat that has gained notoriety for its ability to wreak havoc on computer systems and cause significant data loss.
This malicious software is designed to infiltrate a system, encrypt files, and demand a ransom payment from the victim in exchange for the decryption key.
"The Lazarus Group, a hacker collective with ties to the North Korean government, has had a busy year, with the U.S. government seizing $30 million worth of cryptocurrency stolen by the group in a play-to-earn game scheme in early 2022. Between February and July of that year, Lazarus targeted energy providers in Canada, Japan, and the United States, using vulnerabilities in VMWare Horizon and deploying malware to gain initial access to the organizations."
Conti ransomware is a formidable adversary in the world of cybercrime. What makes Conti ransomware so dangerous is its ability to spread quickly and evade detection by the security software, making it difficult to contain and neutralize.
Organizations targeted by Conti ransomware must act fast to mitigate the damage and prevent further data loss.
"Conti group targeted the Costa Rican government and launched Distributed Denial of Service (DDoS) attacks on Cobalt Strike servers.
The group also targeted the Ukrainian government and various Ukrainian and European humanitarian and non-profit organizations during the Russia-Ukraine conflict. While Conti had previously expressed support for Russia, they later pulled back.
According to Google’s Threat Analysis Group, the group used phishing emails impersonating the National Cyber Police of Ukraine to target their victims."
The Hive ransomware is known for its ability to remain undetected and spread quickly, causing widespread damage and disrupting business operations.
If you fall victim to this malware, you can expect significant financial losses, lost productivity, and potential reputational damage.
"As of November 2022, the FBI has reported that the Hive ransomware group has affected over 1,300 companies worldwide, extorting approximately $100 million in ransom payments. Hive operates using the ransomware-as-a-service (RaaS) model, in which developers create, maintain, and update the malware, while affiliates conduct the actual ransomware attacks.
From June 2021 through at least November 2022, Hive has targeted a wide range of businesses and critical infrastructure sectors, including government facilities, communications, critical manufacturing, information technology, and healthcare and public health (HPH) in particular."
Black Basta ransomware is a menacing threat that can cause significant damage to computer systems and hold valuable data hostage. It is difficult to detect and prevent.
"One of the key features of this ransomware is its ability to delete all Volume Shadow Copies and replace them with a new JPG image set as the desktop wallpaper, as well as an ICO file representing the encrypted files.
The files targeted by Black Basta are encrypted using the ChaCha20 algorithm, with the key and nonce being encrypted using a hard-coded RSA public key."
One wrong move and you could end up in a worse situation than before. But when your company's data is on the line, it's tempting to do whatever it takes to get it back. One option is to pay the ransom. But is it worth it? While it may seem like a quick fix, it can set a dangerous precedent and make you a target for future attacks. On the other hand, refusing to pay may mean losing valuable data forever. It's a delicate balance, but one thing is certain: negotiating with cybercriminals should never be taken lightly. Remember that negotiating with cybercriminals is a tricky business.
Human Firewall is enough for raising Awareness to combat social engineering-driven ransomware attacks.
Let’s learn about the Protection Against Ransomware, Best Practices, and Prevention Strategies:
As technology continues to advance, so do the methods and sophistication of cybercriminals. Ransomware attacks have become a pervasive threat, causing millions of dollars in damages and disruptions to businesses and individuals alike.
Today, more than ever, it's crucial for individuals and organizations to take cybersecurity seriously and take proactive measures to protect their digital assets. Beyond today, the future of ransomware attacks remains uncertain. One thing is for sure: the only way to stay ahead of these malicious attacks is to stay informed, stay vigilant, and stay prepared. Prevention is always better than cure when it comes to cybersecurity.
