“Ransomware is not only about weaponizing encryption, its more about bridging the fractures in the mind with a weaponized message that demands a response from the victim.” - James Scott, Senior Fellow, Institute for Critical Infrastructure Technology Businesses can reduce their vulnerability if they know how to prevent ransomware. While this type of malware does not draw much attention, it can be much more devastating than other types of malware. As ransomware attacks are sophisticated in nature, many larger financial organizations have their own call centers for handling these types of data breaches. Ransomware contributes to 10% of all breaches, but it doubled its frequency in 2021. 37% of global organizations are victims of ransomware attacks. According to the Cybersecurity and Infrastructure Security Agency, 14 of the 16 U.S. critical infrastructure sectors faced ransomware attacks in February 2022. There are more than 130 different ransomware strains detected. Ransomware usually stops the user from using the system, programs, or files. Hackers ask you to pay a ransom to regain control of the PC. You may have to pay to avoid losing everything. As backups may not provide complete protection against ransomware attacks, this malware is considered essential. It shows the importance of depending upon a professional security service. Read the article to know more about how to detect and prevent potential data breaches through ransomware effectively. How to Detect Ransomware Attacks It is hard for traditional antivirus software to detect ransomware because this advanced malware uses a set of complex evasion techniques. Therefore, it has become essential to educate yourself and your employees on ways to detect ransomware before it damages data in your system. Ransomware creators apply advanced social engineering tricks and military-grade encryption algorithms to take control of your system and encrypt your data. Unfortunately, it becomes difficult to recognize which files are infected as the ransomware can scramble files. In 2018, 180,000 users globally had been infected with ransomware. Due to the increasing number of ransomware attacks, it has become imperative to know how to detect and prevent ransomware attacks in time. Below are some of the tips on how to detect ransomware. Through a similar-looking email account, ransomware creators send malicious emails. For example, they use capital letters instead of the small letters in the original email ID. So, it is important to learn how to spot ransomware by paying close attention to the email addresses. Another thing is to check the content of the email thoroughly, especially if it has sensitive information. Modern ransomware creators are so sophisticated that they even cleverly imitate emails and even the writing voice of the institution or person. Do not do anything suggested in the mail content if you sense anything strange. The best thing to do is to call the person or organization involved to check the email's authenticity. If you doubt the authenticity of the email, do not click on the links in the email immediately. Closely assessing the email can give you hints as to whether the email is genuine or not. In addition, you can check for unusual domains and spelling errors in the email. Another effective way to detect ransomware is to be careful while downloading attachments. Ransomware creators hide it in an encrypted zip file. You won’t be able to see the malicious file encrypted until you extract it from the file. Tips to Prevent Ransomware Attacks Avoid Providing Personal Data to Unknown Do not give out personal information if you receive a call, text, or email from an unknown source asking for it. Before a ransomware attack, there is a possibility that cybercriminals may try to obtain personal information. This information can be used to target individuals personally through phishing emails. The goal is to get you to open a malicious attachment or link. Permitting the perpetrators to access data to make their trap more plausible is not a good idea. If a corporation contacts you for information, ignore the request and contact the company on your own to confirm that it is legitimate. Get Security Software Assistance As cybercrime increases it becomes essential to have ransomware protection. Use a comprehensive internet security solution like Kaspersky Internet Security to protect your PC from ransomware. Software stops corrupted files from being downloaded or streamed, preventing ransomware from getting into your system and keeping hackers away. Back up your data It is always a good idea to keep a backup of your data. In case you are hit by ransomware, you will know that your data is safe. Keep everything on a hard drive, but don't leave it attached to your computer while you're not using it. Leaving the hard drive attached to your system can compromise the data if you become a victim of ransomware. The data inside the hard drive can get encrypted. With cloud storage solutions, you can also go back to previous versions of your files. As a result, if ransomware encrypts them, you should be able to restore an unencrypted version using cloud storage. Click Only on Verified Links Clicking links on unfamiliar websites or in spam emails should be avoided. One way for your computer to become infected is through downloads that begin when you click on malicious links. When ransomware infects your computer, it either encrypts your files or locks down your operating system. Once the ransomware has anything to hold as a 'hostage,' it will demand to unlock your files. The simplest solution is to pay the ransoms. However, this is what the criminal wants you to do, and paying the ransom does not guarantee that you will be able to access your device or data. Do Not Download Software from Unknown Websites To make sure that you do not get ransomware, don’t download software or media assets from unknown websites. If you want to download something, go to a site that has been verified and is reputable. Most reputable websites will have trust indicators that you can spot. For example, type “https” into the search field to see if the site uses “https” rather than “http”. A shield or lock symbol may appear in the address bar, to confirm that the site is secure. If it’s something that you want to download for your phone, be sure it's from a trusted source. For example, Android users should download apps from the Google Play Store, while iPhone users should go to the App Store. What to Do in Case You Have Become a Victim of Ransomware What if you've already been under a ransomware attack and you are unaware of it? It's critical to know what to do in the event of a ransomware attack. Here are some easy steps that may help reduce damage to some extent. If you're hit by ransomware, the first thing you should do is disconnect from all networks and the internet. By disconnecting, you isolate your computer and limit the ransomware virus from spreading to other devices. It's advisable to consult a cybersecurity professional before paying ransom to cybercriminals. They will learn the situation and advice you to act accordingly. Summing Up Ransomware is difficult to detect and defend against. Organizations, on the other hand, can take steps to protect their systems and sensitive data by taking necessary precautions. The first thing to do is to educate employees about common red flags and vulnerabilities, set up processes and procedures for preventative monitoring, and install anti-ransomware software and tools. Frequently Asked Questions How does ransomware work? Ransomware encrypts files on a computer and prevents the user or organization from accessing them. This malware encrypts files and demands a ransom for the decryption key. This puts businesses in a situation where paying the ransom is the most convenient way for them to get back the data. Is it possible to remove ransomware? Robust cybersecurity software can be used to decrypt ransomware files. A cybersecurity specialist should assist you at every step of the ransomware eradication process with the ransomware removal tool. However, retrieving all the files may not always be possible. Is it possible to detect ransomware? Ransomware can be identified at the network level by checking for unusual traffic patterns. This can signal a ransomware infestation or malware in general.

“PAM is part of the journey, not the destination, so have a roadmap and make sure you communicate with your team and wider operation, which will allow for your overall security strategy to progress.” - Terence Jackson, Thycotic CISO and Privacy Officer. In a corporate context, "privileged access" refers to special access or capabilities that go beyond the scope of a standard user's profile. With the help of privileged access, businesses can protect their infrastructure and applications, operate more efficiently, and keep important data safe. Privileged access can include human and non-human users but does not necessarily represent a human user. For example, a human user’s privileged access can be domain administrative accounts, superuser accounts, and secure socket shell (SSH) keys. On the other hand, some examples of non-human privileged access are service accounts, application accounts, secrets, and SSH keys. In the last decade, there have been numerous security breaches involving privileged access. Among them are the following: The massive breach happened at the U.S. Office of Personnel Management Bangladesh bank breach The attack on the Ukrainian power grid Uber’s highly publicized breach All of these hacks used privileged credentials to plan, organize, and execute cyber-attacks. Privileged Access Management Privileged access management (PAM) is used by organizations to safeguard against the hazards caused by credential theft and misuse of privilege. PAM refers to a holistic cybersecurity approach that includes people, procedures, and technology for controlling, monitoring, securing, and auditing all human and non-human privileged identities. It also allows actions to be taken throughout an enterprise's information security environment. Privileged access management (PAM) works on the concept of least privilege, where the users have access to what is necessary to accomplish their jobs. The idea of least privilege is generally regarded as a recommended practice in cybersecurity and is a critical component of safeguarding privileged access to high-value data and assets. To cut down on their attack surface, companies may be able to reduce the risk of costly data breaches from hostile insiders or cyberattacks from outside the company. Key Challenges When it comes to protecting, controlling, and monitoring privileged access, organizations face numerous challenges. Some of them are as follows: Many IT organizations rely on manual-intensive, error-prone administrative processes to rotate and update privileged credentials. This can be a costly and inefficient approach. While centralized monitoring and controlling privileged sessions puts the business at risk for compliance violations and cybersecurity threats, enterprises also put the business at risk. Many businesses do not use threat analysis tools, so they cannot proactively remediate security incidents. Organizations often struggle to control privileged user access to social media, Software as a Service (SaaS) applications, cloud platforms, and others. As a result, it creates compliance risks and operational complexity. Attackers can use flaws in the Kerberos authentication protocol to impersonate authorized users and get access to important IT resources and confidential data. Why does Your Business Need PAM? The statistics below highlight, in brief, the necessity of PAM for businesses: 3% of organizations lack a mature approach to access management, resulting in two times the number of breaches U.S. enterprises lose $7.91M from a breach, almost double the global average of $3.68M 56% of breaches take months or longer to discover 49% of organizations don’t have policies for assigning privileged user access 80% of security breaches involve compromised privileged credentials 90% of organizations feel vulnerable to insider attacks Traditional Cybersecurity Vs. Privileged Access Management (PAM) Regrettably, traditional cybersecurity is no longer a viable solution. It is complicated, difficult to manage, too costly, and time-consuming. As a result, businesses have to speed up their transition to simpler solutions that don't depend much on IT staff and have more secure, easy-to-use interfaces. Privileged access management is currently a priority for many CISOs to mitigate the risk of cyberattacks, empower their staff, and safeguard their enterprises from unwanted access. Read on to understand some of the critical reasons why you should shift from traditional cybersecurity to privileged access management (PAM). Quick Response When Privileged Accounts Are Hacked Many businesses are afraid to think about what can happen if an administrator account is compromised. However, it is still possible. All accounts can be hacked. A company can't always rely on administrators to take the proper steps, even if they should. A well-designed PAM (privileged access management) system will safeguard against privileged account attacks. Privileged accounts can be disabled swiftly to prevent further damage. The more quickly threats are addressed, the less damage is done to the system. Zero or Lower Chances of Insider Threats Malicious insiders can be a major threat to the organization. Once someone has accessed your system, your data may be readily compromised. With PAM, an insider's ability to harm your system is significantly restricted. They cannot install malware on machines and access documents and data that they are not authorized to view. Also, they will not be able to change the network settings. Improved Regulatory Compliance Regulations are either constantly changing or upgraded. Businesses must adhere to these standards to avoid substantial fines and penalties. PAM promotes regulatory compliance by giving administrators more power and employees less. Employees who don’t pay much attention may violate these restrictions. Either they are unaware, or they are not concerned. By not giving employees access to things they don't need, it's possible to reduce the chances of regulatory compliance issues. An organization is more likely to be in compliance if it uses privileged access management software and learns how to use it in real life. Lower Chances of Malware Risk Employees may install malware, even without recognizing it. For example, they may download anything from the web or accidentally click on a link in an email. They may also unknowingly permit a download or installation that they should not. Privileged access management prevents employees from making these types of catastrophic errors by restricting them from making such modifications. As a result, potential hazards are decreased, and the assault surface is lowered. Proactive PAM Program Protect Endpoints and Workstations Effectively In a business, every endpoint (laptop, smartphone, tablet, desktop, and server, for example) comes pre-configured with privileges. While built-in administrator accounts assist IT staff in resolving local problems, they also present a significant amount of risk. Attackers attack admin accounts and then go from one workstation to the other, hacking new credentials until they accomplish their objective. Workstations are less likely to be hacked if their local administrative privileges are taken over by a privileged access management program in the early stages. Summing Up Privileged access management (PAM) is a cybersecurity term that refers to the techniques and technologies used to control privileged access and rights in their accounts, processes, and systems in an IT environment. Privileged access management helps businesses reduce their attack surface and prevent data breaches. It can, at least, lessen the damage caused by outside threats and internal misuse or neglect. Frequently Asked Questions Is there any difference between IAM and PAM? IAM, also known as identity and access management, is concerned with the management of all users. On the other hand, PAM makes sure that administrative and privileged users can have access to specific information. It can be done by defining and regulating the roles of the admin users. Why do businesses need PAM? PAM allows enterprises to protect themselves against accidental or deliberate misuse of privileged access by facilitating the authorization and monitoring of privileged users Who is a privileged user? A user who is permitted (and hence trusted) to perform duties that involve sensitive data. Regular users do not usually perform these duties.

NETWORK THREAT DETECTION

Article | March 31, 2022

Cybersecurity threats and vulnerabilities are prevalent in all types of businesses, from Fortune 500 companies to mom-and-pop shops. The basic fact is that there are far too many risks to counteract all of them adequately. According to Kaspersky Lab, a leading antivirus company, “The number of new malicious files processed by Kaspersky Lab’s in-lab detection technologies reached 360,000 a day in 2017.” This contributes to 250 new malware threats every minute. When it comes to cybersecurity threats and network vulnerabilities, malware is not the only thing to be worried about. Hackers can steal your data and sensitive information. Cybersecurity Threats and Vulnerabilities: The Difference To put it simply, vulnerabilities are weaknesses or flaws in a system or network that could be exploited to bring harm or allow an attacker to manipulate the system in some way. This differs from a cyber-threat. Computer system vulnerabilities are the weaknesses and flaws present in the system, unlike a cyber threat. Cybercriminals will also use these flaws in their attacks, but they aren't usually the result of a deliberate plan. I short, vulnerabilities lead to cybersecurity threats. How a computer cybersecurity vulnerability is exploited is determined by the nature of the exposure and the attacker's motivations. For example, these problems could be caused by software programs that don't work well together, system parts that don't work well together, or flaws in a single application. Top Cybersecurity Threats and Vulnerabilities of the Year Internet of Thing Devices The Internet of Things (IoT) includes many smart devices, such as Wi-Fi-equipped refrigerators, printers, factory robots, coffee makers, and countless other appliances. The challenge with these devices is that attackers can use them to create slaved networks of compromised devices to carry out additional attacks. Worse yet, many firms are unaware of how many IoT devices they have on their networks. This means they are unaware of the risks and possible threats they are exposed to, as well as the vulnerabilities to information security. These unknown devices provide countless opportunities for attackers and increase the vulnerability risk in cybersecurity for corporations. To reduce the network security threats and vulnerabilities of IoT devices, a security audit should be conducted that identifies the diverse assets of the network and the operating systems they use. In this manner, the company's cybersecurity plan can effectively account for these IoT devices. In addition, audits like these should be done regularly to account for any new devices added to the network over time. Phishing Attacks or Social Engineering In a phishing attack, the attacker tries to persuade an employee of the targeted organization to divulge important information and account credentials by prompting them to download malware. The most common attack is through identical emails from one of your company's vendors or someone from a higher level. One such example of a phishing email is: "This is Mark from IT. Your user account has shown unusual behavior. Please click this link to reset and secure your password." When you click the link in the email, it directs users to a website that downloads malware and compromises their machine. Other phishing scams may try to get people to handover their user account credentials to the attacker to resolve a problem. Malware New malware is generated regularly. The figure of 360,000 new malware files every day may appear alarming. Many of these new malware files are simply rehashes of earlier malware programs that have been tweaked just enough to make them unidentifiable to antivirus software. However, numerous new types of malware have been developed over time, such as ransomware, trojans, and worms, each uniquely affecting the target's systems. Security Vulnerabilities That Are Unpatched As new sophisticated threats are produced regularly, companies have to find sophisticated ways to tackle them perfectly. Malware is looking to exploit the same cybersecurity threats and vulnerabilities repeatedly. Failing to patch those cybersecurity vulnerabilities, once they're discovered, it can be dangerous for companies. It's all too usual for a company—or even individual users on a network—to ignore the ‘update available’ warnings that appear in some programs because they don't want to waste the 5-10 minutes to perform the update. These updates can save a company a lot of time and money and save from threats. Thus, it is good for companies to update programs regularly. Backdoor Programs that Are Hidden This is an example of a computer cybersecurity vulnerability that was purposefully engineered. Usually, a backdoor is a piece of software or code that is installed by the manufacturer of computer parts, software, or entire machines. This allows the manufacturer to access a computer remotely for diagnostic, configuration, or technical support purposes. A hidden backdoor program installs a backdoor into a computer without the knowledge of the user. Secret backdoors are a significant software flaw because it is easy to gain unauthorized access and affect the computer system and the networks to which it is connected. Employees The employees working for an organization are considered to be cybersecurity vulnerabilities. Most data breaches can be traced back to an employee due to intentional mistake or an accident. Employees, for example, may take advantage of their access credentials for personal gain. Alternatively, an employee could click on the wrong link in an email, download the wrong file from a website, or give the wrong person their user account credentials, giving attackers simple access to your systems. Using a least privilege policy, for example, prevents users from having too much data at once, making it difficult for them to steal data. Another benefit of cybersecurity awareness training is that it helps employees recognize phishing and other social engineering-style attacks and not fall for them. Software or Programming Interfaces With Unknown Security Flaws Computer software is complicated to comprehend. The complexity of a system grows exponentially as two or more programs interact with one another. The problem is that there may be programming flaws and conflicts inside a single piece of software, resulting in cybersecurity threats and vulnerabilities. When two applications are linked together, the chance of disputes that result in software flaws increases. Programming errors and unexpected code interactions are the most frequent cybersecurity vulnerabilities. Cybercriminals constantly seek new ways to exploit them. Unfortunately, forecasting the emergence of these threats and vulnerabilities to information security is not possible because of the infinite number of software combinations that can exist on a single computer, let alone an entire network. 3 Ways to Find and Prevent Cybersecurity Threats and Vulnerabilities Identifying vulnerabilities in cybersecurity before an attacker can exploit is one of the essential steps in preventing a security breach. Many firms, however, does not have the tools and expertise to identify network security threats and vulnerabilities. Here are some ways to find threats and vulnerabilities in information security: Audit Your Network Assets Penetration Testing Create a Threat Intelligence Framework Summing Up Cybersecurity threats and vulnerabilities have become too sophisticated as our dependency on digital technologies grows. It is because of this companies that use outdated cybersecurity techniques are at a risk of being hacked. Organizations must improve their cybersecurity program to avoid risks. An effective cybersecurity program can assist firms in preventing attacks, reducing recovery time, and containing future risks. Frequently Asked Questions What do you mean by cyber threats and vulnerability? Vulnerabilities are gaps in a system that allow threats to occur and let threat actors take advantage of the data. It is called a threat when the chance of an attack is multiplied by the possible loss. What are some of the vulnerabilities in cybersecurity? Network vulnerabilities, operating system vulnerabilities, human vulnerabilities, and process vulnerabilities are some of the vulnerabilities in cybersecurity. What is the difference between vulnerability and threat? A threat is a process that increases the possibility of an adverse event, such as a vulnerability being exploited. On the other hand, exposure is a flaw in your infrastructure, networks, or apps that could expose you to threats.
