How Do Ransomware Attacks Happen?
Ransomware is not just a type of malicious software hackers use to encrypt data and demand payment for decryption. It poses a serious threat to any company’s or organization’s internal infrastructure.
In this article, we’ll not only take an in-depth look at what they are, but also the circumstances in which ransomware attacks happen, the different types of variants that have been identified, a step-by-step process to preventing attacks, and the benefits of managed network security services like First Class Connection.
What Are Ransomware Attacks?
Ransomware attacks are becoming increasingly common and can devastate businesses. These cyberattacks grant hackers access to a system, where they then install malware that encrypts sensitive data. The attacker then demands payment to decrypt the files, making them inaccessible until the ransom is paid. But how exactly do ransomware attacks happen?
How Do Ransomware Attacks Happen?
There are several different ways that hackers can gain access to a system and deploy malicious software. Phishing emails are one of the most popular methods, as they rely on social engineering tactics like impersonating legitimate businesses or individuals to trick users into clicking links or downloading malicious code attachments. Unsecured networks, outdated software, and poor password practices can also make systems vulnerable, allowing for easy access by hackers.
Ransomware Mitigation
Mitigating risks involves a combination of preventative measures and contingency planning. First and foremost, regular backups of critical data should be taken and stored offline. This ensures that even if an attack occurs, data can be restored without paying the ransom. Your team should also implement network security measures to prevent unauthorized access and limit the spread of malware. Employee education and awareness training are also essential to help prevent phishing and social engineering attacks, often used to deliver ransomware.
Covering up these vulnerabilities requires a well-prepared incident response plan with clearly defined roles and responsibilities, to ensure that any ransomware attack can be quickly and effectively eliminated. Hiring a third-party partner, like First Class Connection, can streamline the entire process.
Ransomware Variants
Understanding the different types of ransomware variants can help you better protect yourself against these attacks. It is crucial to keep your software up to date, use anti-virus software, and be cautious when opening email attachments or downloading files from untrusted sources. Let’s identify a few of these variants:
Crypto Ransomware
Crypto ransomware is the most common type. This variant encrypts the victim’s files, making them inaccessible until a ransom is paid. The attacker typically demands payment in cryptocurrency, such as Bitcoin, in exchange for the decryption key.
Crypto ransomware can infect a victim’s infrastructure through various methods, including phishing emails, malvertising, and software vulnerabilities. Once installed, it will search for files and encrypt them using a strong algorithm. Some of the most well-known examples include WannaCry, Locky, and Cryptolocker.
Locker Ransomware
Locker ransomware locks an organization out of its computers, preventing them from accessing its files or even logging in. This type typically presents a message on the victim’s screen that demands payment in exchange for the unlocking of the computer.
Locker ransomware can be delivered through various methods, including email attachments, malicious downloads, or software vulnerabilities. Some of the most well-known examples include FBI Moneypak and CryptoLocker.
Scareware
Scareware uses tactics to trick the victim into paying a ransom. This variant typically displays a fake message that claims the victim’s computer has been infected with a virus or malware. The message will then demand payment in exchange for removing the supposed infection.
Scareware can be delivered through various methods, including pop-up ads, email attachments, or malicious downloads. Examples of scareware include Antivirus 2009 and Mac Defender.
Doxware
Doxware threatens to release the victim’s or an organization’s sensitive data, such as personal information or confidential documents, if a ransom is not paid. This variant is often used to target businesses or high-profile individuals, or companies who may have valuable data on their computers.
Doxware can be delivered through various methods, including phishing emails or malicious downloads. One of the most well-known examples is Maze.
Mobile Ransomware
Mobile ransomware targets mobile devices, such as smartphones and tablets. It typically encrypts the victim’s data or locks them out of their device until a ransom is paid. Examples include Simplocker and Android/Filecoder.C.
