    How LockBit Ransomware Has Changed?

    Understanding LockBit 3.0 helps one to know how it started and grew over time. Let’s look at its evolution:

    When LockBit First Appeared

    LockBit showed up in September 2019. It quickly became famous among cybercriminals. The first version, LockBit 1.0, was sold as a service. This meant other criminals could use it to attack computers if they shared the money they made.

    LockBit 1.0 stood out because of its fast encryption process. It could lock files much quicker than other ransomware at the time. This speed made it harder for victims to stop the attack once it started. The creators also focused on making it work well on Windows computers, which are common in businesses.

    LockBit 2.0: Getting Stronger

    In June 2021, the criminals behind LockBit released version 2.0. This new version was faster and better at avoiding detection. It could also steal data and attack entire networks, not just single computers.

    LockBit 2.0 introduced several new features:

    • It could spread automatically through a network, infecting more computers.
    • It had better ways to hide from security software.
    • It could use different methods to get into computer systems.
    • The attackers started a “double extortion” tactic, threatening to leak stolen data if the ransom wasn’t paid.

    These improvements made LockBit 2.0 much more dangerous and successful in its attacks.

    The Arrival of LockBit 3.0

    LockBit 3.0, also called “LockBit Black,” came out in June 2022. This latest version is a big step up in ransomware technology. It has new features and a smarter way of doing business. LockBit 3.0 shows that ransomware is becoming more advanced and dangerous.

    Some key advancements in LockBit 3.0 include:

    • Even faster encryption speed.
    • More options for customizing attacks.
    • Improved methods for stealing data.
    • A bug bounty program, offering rewards for finding weaknesses in their software.
    • Better tools for negotiating with victims.

    These changes have made LockBit 3.0 one of the most sophisticated and widely used ransomware strains in the world.

    What LockBit 3.0 Can Do?

    LockBit 3.0 has many features that make it one of the most dangerous ransomware out there. Here’s a deeper look at what it can do:

    What LockBit 3.0 Can Do - Softwarecosmos.com

    Strong Encryption

    LockBit 3.0 uses very strong encryption to lock files. This makes it extremely hard to unlock files without the right key. Victims often can’t get their data back without paying or having a good backup.

    See also  What is Social Engineering in Cyber Security?

    The encryption process uses a combination of public and private key cryptography. This means each attack uses a unique set of keys, making it nearly impossible for security researchers to create a universal decryption tool. The encryption is so strong that even powerful computers would take years or even centuries to crack it without the right key.

    Fast File Locking

    One of the scariest things about LockBit 3.0 is how fast it can lock files. It can encrypt lots of data in just minutes. This quick action makes it hard to stop the attack once it starts.

    The speed comes from several factors:

    • It uses efficient coding techniques to process files quickly.
    • It can encrypt multiple files at the same time (parallel processing).
    • It focuses on encrypting the most important parts of files rather than entire files, which is faster.

    This rapid encryption often means that when an organization realizes they’re under attack, it’s too late to prevent widespread damage.

    Spreading on Its Own

    LockBit 3.0 can spread through networks on its own, like a worm. Once it gets into one computer, it can find ways to infect others connected to it. This means one infected computer can lead to a whole network being attacked.

    The self-spreading capability works by:

    • Exploiting vulnerabilities in network protocols.
    • Using stolen login credentials to access other machines.
    • Taking advantage of misconfigured network shares.
    • Utilizing built-in Windows tools to move laterally within the network.

    This feature makes LockBit 3.0 particularly dangerous in corporate environments where many computers are connected.

    Hiding from Security Software

    To avoid being caught by antivirus programs, LockBit 3.0 uses clever tricks. It can change how it looks to security software and stop processes that might interfere with it.

    Some of these evasion techniques include:

    • Using “fileless” malware techniques that don’t leave easily detectable traces on the hard drive.
    • Encrypting its code to make it harder for security software to recognize.
    • Disabling Windows Defender and other security tools.
    • Using legitimate Windows processes to hide its activities.

    These methods make it challenging for traditional security software to detect and stop LockBit 3.0 before it’s too late.

    Stealing Data

    Besides locking files, LockBit 3.0 can also steal sensitive data. This puts extra pressure on victims to pay, as they worry about their information being leaked or sold.

    The data theft process typically involves:

    • Searching for specific types of valuable files (like financial records or personal information).
    • Compressing and encrypting the stolen data to prepare it for exfiltration.
    • Using stealth techniques to send the data to servers controlled by the attackers.

    This “double extortion” tactic has become increasingly common in ransomware attacks, as it gives criminals more leverage over their victims.

    How a LockBit 3.0 Attack Happens?

    Understanding how LockBit 3.0 attacks work can help you protect against it. Here’s a more detailed look at how a typical attack unfolds:

    How a LockBit 3.0 Attack Happens - Softwarecosmos.com

    Getting In

    First, attackers need to get into a computer system. They might:

    • Send fake emails with harmful attachments
    • Use stolen passwords
    • Trick people into giving them access

    The initial access methods can be quite sophisticated. For example:

    • Phishing emails might impersonate trusted brands or even colleagues.
    • Attackers might use social engineering tactics, like calling employees and pretending to be IT support.
    • They might exploit vulnerabilities in public-facing services, like web servers or VPN gateways.

    Once they have a foothold, the attackers work to gain higher-level access privileges within the network.

    Looking Around

    Once inside, the attackers explore the network. They look for important data and systems to target.

    This reconnaissance phase often involves:

    • Using network scanning tools to map out the organization’s infrastructure.
    • Identifying critical servers and databases.
    • Looking for security weaknesses that can be exploited.
    • Gathering information about the organization’s backup systems and security measures.

    The attackers use this information to plan their attack for maximum impact and to determine how much ransom to demand.

    Turning Off Security

    Before starting the attack, LockBit 3.0 tries to shut down security measures. This might include stopping antivirus software or deleting backups.

    Specific actions might include:

    • Disabling Windows Defender and other security software.
    • Deleting Volume Shadow Copies, which are used for system restore points.
    • Modifying Windows Registry settings to prevent certain security features from working.
    • Stopping database services to ensure all files can be encrypted.

    By neutralizing these defenses, LockBit 3.0 ensures its encryption process can run unimpeded.

    Locking Files and Demanding Money

    LockBit 3.0 then starts encrypting files quickly. It leaves ransom notes explaining how to pay to get the files back. The attackers might also threaten to leak stolen data if the ransom isn’t paid.

    The encryption process typically:

    • Targets specific file types, focusing on important documents, databases, and backups.
    • Renames files with a new extension (like .lockbit) to show they’ve been encrypted.
    • Places ransom notes in each folder and on the desktop.

    The ransom demands are usually in cryptocurrency (like Bitcoin) and can range from thousands to millions of dollars, depending on the organization’s size.

    Negotiating and Payment

    Victims might try to negotiate the ransom if they decide to talk to the attackers. However, paying doesn’t guarantee getting your files back and might encourage more attacks.

    The negotiation process often involves:

    • Communication through a special website on the dark web.
    • Proof from the attackers that they can decrypt files.
    • Haggling over the ransom amount.
    • Arrangements for secure payment methods.
