The WannaCry attack served as a wake-up call for organizations around the world to take cybersecurity seriously and implement measures to protect against similar attacks in the future.


Cerber Ransomware is a dangerous malware that has been causing havoc in the cyber world since its discovery in 2016. It is a type of ransomware that encrypts the victim’s files and demands payment in exchange for the decryption key. Cerber Ransomware uses advanced encryption algorithms to lock the files, making it almost impossible to decrypt them without the key. Once the files are encrypted, the victim is left with a ransom note that provides instructions on how to pay the ransom. Cerber Ransomware is often distributed through spam emails, exploit kits, and malicious websites. It has caused significant financial losses to individuals and organizations, making it a threat that should be taken seriously.


Locky is a type of ransomware that is capable of encrypting up to 160 different file formats, including those commonly used by designers, engineers, and testers. This malware was first introduced in 2016 and has primarily been distributed through phishing attacks. Attackers send emails that are designed to trick the user into opening a Microsoft Office Word or Excel file that contains malicious macros, or a ZIP file that installs the malware upon extraction. Once the malware is installed, it will encrypt the user’s files and demand payment in exchange for the decryption key. It is important for users to remain vigilant and keep their antivirus software up to date to protect against this type of attack.


Cryptolocker ransomware made its debut in 2017 and wreaked havoc on over half a million computers. This malicious software primarily infiltrates computers via email, file-sharing sites, and unprotected downloads. Once inside a system, it not only encrypts files on the infected machine but can also scan mapped network drives, and encrypt files it has permission to write to. To make matters worse, newer variants of Cryptolocker ransomware are capable of evading traditional antivirus software and firewalls. If left unchecked, this unrelenting malware can cause irreparable damage to your computer system and your data.


Ryuk ransomware is a notorious malware that spreads through phishing attacks, using a dropper to extract a trojan onto the victim’s computer. Once the attacker establishes a persistent network connection, they use Ryuk as a basis for an Advanced Persistent Threat (APT), installing additional tools like keyloggers, performing privilege escalation, and lateral movement. The attackers install Ryuk on each system they gain access to, and when they have infiltrated as many machines as possible, they activate the locker ransomware and encrypt the files. However, in a Ryuk-based attack campaign, the ransomware aspect is only the last stage of the attack, after the attackers have already caused damage and stolen the files they need. Protecting your system against Ryuk ransomware is crucial as it can cause irreparable harm to your data and business.


In 2018, GrandCrab Ransomware was unleashed, causing havoc in the world of cybersecurity. This ransomware encrypts files on a user’s computer and demands a ransom, typically in cryptocurrency, in exchange for the decryption key. Attackers even threatened to expose victims’ porn-watching habits if they failed to pay up. GrandCrab Ransomware targets Windows machines and has several versions, each one more advanced than the last. Luckily, free decryptors are available today for most versions of GrandCrab, offering some reprieve for those affected by this malicious software.

Petya and NotPetya

Petya and NotPetya are ransomware that have caused havoc in the computer world. Petya, first seen in 2016, infects a machine and encrypts the entire hard drive by accessing the Master File Table (MFT), making the disk inaccessible. NotPetya, a more dangerous variant, has a propagation mechanism and is able to spread without human intervention. It originally spread using a backdoor in accounting software used widely in the Ukraine. Petya and NotPetya only affect Windows computers and require the user to give permission to make admin-level changes before encrypting the disk and showing the ransom notice. It is crucial to stay vigilant and protect your computer from these harmful ransomware attacks.

Ransomware is one of the most dangerous and frightening types of malware that can infect your computer. It is a type of malicious software that locks you out of your computer or encrypts your files until you pay a ransom. Ransomware attacks have been increasing in recent years and have become a serious threat to both individuals and businesses. In this blog post, we will explore the different techniques that cybercriminals use to distribute ransomware. Understanding these techniques can help you recognize and avoid ransomware infections.

Phishing Emails

One of the most common ways that ransomware is distributed is through phishing emails. Cybercriminals send emails to potential victims that look like they are from legitimate companies or organizations. These emails often contain a link or attachment that, when clicked, will download and install the ransomware on your computer.

Drive-By Downloads

Another common method of distributing ransomware is through drive-by downloads. This occurs when a user visits a compromised or malicious website and unknowingly downloads the ransomware. The malware is often disguised as a legitimate file or program, making it difficult to detect.


Malvertising is a term used to describe online ads that contain malicious code. Cybercriminals can use malvertising to distribute ransomware by purchasing ad space on legitimate websites. When someone clicks on the ad, the ransomware is downloaded onto their computer.

Remote Desktop Protocol (RDP) Attacks

Remote Desktop Protocol (RDP) is a feature that allows users to log in to their computer remotely. Cybercriminals can use RDP attacks to gain access to a victim’s computer and install ransomware. This type of attack is particularly dangerous because many people use weak or easily guessable passwords for their RDP accounts.

Social Engineering

Social engineering is a type of attack that relies on psychological manipulation to trick victims into downloading or installing ransomware. Cybercriminals may use social engineering tactics such as posing as a legitimate business or organization to gain the trust of their victim.



Ransomware is a type of malware that causes havoc to devices and systems. It infiltrates a device’s network through various means, including email attachments, downloads, and exploit kits. Once it has infiltrated a device, the ransomware begins its seven-stage attack. In this blog post, we’ll discuss each stage of a ransomware attack and how it works.

  • Stage 1 : Infection

    The first stage of a ransomware attack is infection. This is the stage at which the ransomware gains access to a device’s network. This can occur through several means, including phishing emails, malicious links, or exploit kits. Phishing emails are common ways ransomware infects devices. They appear to be legitimate communications from trusted sources such as banks, social media, or online stores. The email usually contains a malicious attachment with the ransomware code.

  • Stage 2: Execution

    After gaining access to the device, the ransomware code is executed. This is the stage where the ransomware can affect the device’s performance and functionality. Malicious code embedded in the ransomware begins to run and spread across the device and its network, looking for files to encrypt.

  • Stage 3: Encryption

    Once the ransomware has established itself on the device, it then begins to encrypt files on the device’s hard drive. Encryption is the process of converting normal data into a code that is meaningless and undecipherable. The ransomware typically uses either symmetric or asymmetric encryption to lock the files. This process typically happens quickly, and once a file is encrypted, it is no longer usable.

  • Stage 4: User Notification

    After the files have been encrypted, the ransomware will notify its victims. This notification is usually in the form of a pop-up message or a text file that presents itself on the device’s screen. Ransomware victims are typically instructed to pay a specific amount of money to receive a decryption key that will unlock the encrypted files. The message usually includes threats to delete the files permanently if the ransom isn’t paid.

  • Stage 5: Cleanup

    After the ransomware has notified its victims, it begins to clean up the evidence of its activity. This can involve deleting any log files or other traces of the attack that could lead to the discovery of the ransomware.

  • Stage 6: Payment

    To get their files back, the victims of a ransomware attack need to pay a certain amount of money. This is usually in the form of cryptocurrency, such as Bitcoin. Victims are often required to communicate with the ransomware operators through anonymous messaging services to facilitate the payment process. Please do not pay them they are the hackers after payment they demand more or maybe they generate the link attack again after sometimes.

  • Stage 7: Decryption

    Once the ransom has been paid, the ransomware operators will typically provide the victim with a decryption key to unlock the encrypted files. This key may work correctly, or it may not work at all. In some cases, the decryption key may be incomplete, resulting in some files being permanently lost.

In conclusion, ransomware is a severe threat to both individuals and businesses. Understanding how it operates can help people take appropriate measures to protect their devices from an attack. Prevention is always better than cure, and users should invest in robust anti-malware software and be mindful of unusual-looking emails, links, and attachments. This will help reduce the risk of a ransomware attack occurring and minimize the damage if one does occur.


Ransomware Protection

As cyber attacks continue to evolve and become increasingly sophisticated, the threat of ransomware attacks on businesses has become more prevalent than ever before. The danger of ransomware is that it can completely paralyze a company’s ability to function, hold critical data hostage, and even steal corporate information. That’s why it’s become essential for organizations to understand the threat of ransomware and how to protect themselves and their data against it.

Data backup should be the first line of defense against ransomware. Having a backup eliminates the need to pay any ransom demanded by attackers. Regularly back up files and store them offline or in a secure, remote location. This significantly reduces the likelihood of data loss, along with the chance of exposure to ransomware attacks.

Endpoint Protection

Endpoint security is another example of ransomware protection that is gaining traction today. This refers to safeguarding endpoints – such as network devices, laptops, mobile devices, and desktop PCs – against malware, cyber attacks, and other cyber threats. It’s critical to have comprehensive endpoint security measures in place that can counter different types of malware to reduce the possibility of ransomware attacks.

Application Whitelisting and Control

Application whitelisting sets up a list of pre-approved applications that are allowed to run in your organization. This stops unauthorized programs from executing on your system and helps you mitigate the risk of being infected by ransomware. This type of control is an effective way to protect the endpoints of your organization and help secure the data you value.

Email Protection

Email is a commonly accessed attack vector used by attackers to deliver ransomware. Defending against ransomware in email is about being vigilant and having a robust email security system in place. Some potential solutions to this threat include employing an inbound email filter that detects and quarantines messages that contain possible ransomware threats, introducing a web filter to monitor outbound traffic for signals of malicious behavior, and blocking ransomware downloads.

Network Defenses

Network defenses have become an essential part of any ransomware protection strategy. Network security systems can monitor network traffic and detect malicious behavior, helping identify ransomware attacks before they infect devices. Network protections include firewalls and intrusion detection and prevention systems. Firewalls can prevent malicious traffic from reaching your network, and intrusion detection and prevention systems can spot ransomware attacks and prevent them from causing harm.

Patch Management

Patch management is the process of keeping all software, applications, and technologies always up to date and patched to eliminate any vulnerabilities found. Ransomware attackers take full advantage of vulnerabilities in systems and often penetrate them through old, unpatched holes. A sound patch management strategy must ensure the timely installation of updates and patches that can shut these vulnerabilities down.

Ransomware Detection

Ransomware is one of the most dangerous forms of malware roaming the internet today. Unfortunately, it’s also one of the easiest to fall victim to. With the increasing number of remote workers and the rush to upload data to the cloud, ransomware has become a threat not just to individual users, but to entire organizations. One of the biggest challenges with ransomware is that it can quickly spread throughout an entire network, leaving no option but to pay the ransom or face the loss of sensitive data. That’s why it’s so important to detect any possible ransomware activity as soon as possible.

Luckily, there are several detection and remediation strategies that businesses can use to stay ahead of ransomware attacks. Here are some of the most effective strategies for ransomware detection and removal:

Real-Time Alerting and Blocking

One of the most effective strategies for detecting ransomware is real-time alerting and blocking. This approach works by automating the identification of ransomware-specific read/write behaviour and then blocking users and endpoints from further data access. By quickly identifying and blocking suspicious activity, businesses can prevent the spread of ransomware throughout their network.

Deception-Based Detection

Another powerful ransomware detection strategy is deception-based detection. This approach strategically plants hidden files on file storage systems to identify ransomware encryption behaviours at the earliest attack stage. Any write/rename actions on the hidden files automatically trigger a block of the infected user or endpoint, while continuing to allow access by uninfected users and devices. Deception-based detection measures ensure that only the infected user is blocked from accessing data, allowing for the rest of the network to remain operational.

Granular Reporting and Analysis

Finally, businesses can use granular reporting and analysis to provide detailed audit trail support for forensic investigations into who, what, when, where, and how users access files. This approach allows businesses to quickly identify any suspicious activity and track down the source of any potential ransomware attacks.

If you detect a ransomware infection in your network, it’s important to act quickly. Here are the immediate steps you should take to mitigate the threat:

  • Isolate the infected computer or device from the network to prevent the spread of the ransomware.

  • Identify the type of ransomware and any associated payload files.

  • Attempt to identify the source of the ransomware by examining traffic logs and other network data.

  • Consult with a security professional or IT expert to develop a plan for removing the ransomware and restoring access to any affected files.

By using a combination of detection strategies and proactive prevention measures, businesses can stay ahead of ransomware and protect their sensitive data from attack. Don’t wait until it’s too late; implement these strategies today to safeguard your organization from ransomware threats.
