According to data extracted from a Cybersecurity Ventures‘ survey, ransomware costs will reach $20 billion next year. The survey also predicts this type of cyberattack will target corporations every 11 seconds.

Ransomware consists of malware used by malicious agents to block their victims’ computers and then demand a ransom. This malware has evolved, going beyond encrypting data and causing the shutdown of operations in companies: ransomware such as Maze also causes the leak of sensitive information, endangering the credibility of a company and can generate great financial losses.

The good news is that it is possible to prevent this threat by using Privileged Access Management (PAM), and this is the subject of this article. Keep reading our text to the end and learn everything about it!

• How to Prevent Ransomware Attacks with PAM
• In this topic, we will show you how PAM helps prevent ransomware attacks. In practice, it allows to:
• Know and Manage Privileged Credentials
• Use Protection Strategies Based on Zero Trust
• Implement the Principle of Least Privilege
• Enhance Security in Remote Access
• Audit Actions Performed Through Privileged Credentials

Below, we explain each of these aspects in more detail:

Know and Manage Privileged Credentials

In various types of cyberattacks, hackers use compromised credentials, and ransomware is no different, after all, to run this malicious software one needs to have privileges.

For this reason, it is recommended to discover and manage privileged credentials through Privileged Access Management (PAM). This solution makes it possible to discover, integrate, manage, switch, and audit credentials, as well as eliminate credentials that are no longer in use.

The best PAM tool for the discovery and management of privileged credentials is PAM senhasegura, which has discovery features considered best-in-class by the PAM market.

Use Protection Strategies Based on Zero Trust

Deploying the Zero Trust-based network security model is also essential to prevent ransomware attacks.
This concept considers no user or device should be allowed to connect to IT systems and services without first being authenticated, according to the strategy ?never trust, always verify?.

In practice, the Zero Trust model works as an extremely effective protection, which verifies credentials continuously before granting access through methodologies such as Just in Time.

Just in Time is a technique that offers each user only the necessary access for the required time to perform their activities.With PAM, it is possible to ensure the granular definition of privileges through strategies based on Zero Trust, such as Just in Time. Forrester highlighted the access granularity of senhasegura in its Wave for PIM report.

Implement the Principle of Least Privilege

One of the ways to prevent most ransomware attacks is through the Principle of Least Privilege (POLP).
This strategy also limits the impact of ransomware that can be installed in your IT environment, preventing hackers from moving laterally and diminishing their ability to elevate privileges.

That is, if the malicious attacker steals a credential with limited access or without privileges, the losses will be much lower. In this sense, endpoint privilege management tools are essential features of Privileged Access Management platforms.

This is because the connection of endpoint devices such as IoT devices, smartphones, laptops, and tablets increases the attack surface, making it easier for malicious attackers to work.

senhasegura offers GO Endpoint Manager for Windows and Linux endpoint and workstation privilege management, which allows segregation for access to confidential information, isolating critical environments.

Enhance Security in Remote Access

Remote access is one of the major security vulnerabilities of companies in general. With it, employees and third-party suppliers do not always adhere to the security practices stipulated by the companies. We highlight the choice of weak or reused passwords or the use of the same password by a group of people among the main failures.

With Privileged Access Management, each user will only have access to resources indispensable to performing their tasks, thus reducing the attack surface, since administrators will be able to approve or deny access requests.

Through senhasegura Domum, secure remote access can be performed by employees and third parties with all senhasegura PAM remote session capabilities, providing Zero Trust-based access to corporate network devices without the need for a VPN.

Audit Actions Performed Through Privileged Credentials

Another capability of Privileged Access Management is to facilitate the audit of actions performed through privileged credentials, controlling risks such as improper access to these accounts.

senhasegura enables the implementation of stricter controls, which automate and centralize access to privileged credentials, protecting the IT infrastructure against data theft and compliance failures.
Through senhasegura PAM, it is possible to:

• Obtain automated control of privileged account policies, enabling continuous monitoring and adherence to audit requirements;
• Ensure full visibility of “who, when, and where”, as well as “what” happened during a session with privileged credentials;
• Issue simplified audit reports from a central audit data repository;
• Reduce operational costs and response time with ongoing audits.

Not investing in cybersecurity is a mistake that can cause incalculable loss to organizations. After the Covid-19 pandemic, digital vulnerability has reached alarming numbers with the implementation of the home office work model, bringing the need to develop effective cybersecurity projects to serve the most diverse industries.

The process of developing cybersecurity projects is challenging. With that in mind, our article brings 4 critical factors for the success of this type of action.

Senior Management Support

In a company, all projects of great relevance must go through the approval or refusal of senior management. If the decision is for the implementation of the project, the engagement and cooperation of leaders are essential for the action to be successful. Regarding the adoption of cybersecurity measures, it is no different.

Gaining the support of senior management is one of the critical factors for the successful implementation of a cybersecurity plan. If a company’s management knows and trusts the project’s ability to meet the demands of its business, it will be ready to adopt it.

User Awareness

Presenting the purpose and importance of cybersecurity projects is an essential part of informing and raising users’ awareness. In order to engage employees and show how their actions can affect everyone within a digital environment, training should be applied with practical examples of the dangers posed by cyber risks and showing how to prevent them using the tools and solutions provided by the project.

Moreover, teams should be aware of Incident Response, Disaster Recovery, and Business Continuity Plans. In this way, it will be possible to create a greater sense of responsibility and engagement in all users, and not only in those specifically assigned to the company’s IT area.

Monitoring and Control of Scope, Term, and Budget

The scope of a project contains the mapping of all the work necessary for its progress and completion. It contains the defined goals and each of the stages for implementing the project. Monitoring and controlling the scope is to always remain alert for any changes that may arise in the development of the project, managing which are necessary or dispensable; which are within the budget and schedule available; and which have had approval and agreement from all people involved.

It is still necessary to track each of these changes to obtain an optimization of time and assignment of staff in the establishment of tasks so that the modifications do not negatively affect the project journey.
It is also important to create a project scope statement and make sure all stakeholders understand it. When dealing with external clients, it is also necessary to have a policy of changes and restrictions.

What Is Phishing?

Phishing is a very common type of social engineering in which hackers impersonate legitimate entities or trusted people to manipulate their victims and ask them to perform certain actions, such as providing sensitive information or clicking on malicious links.

Social engineering attacks such as phishing are present in almost all cybersecurity incidents and often involve other threats, such as network attacks, code injection, and malware. 

How Phishing Works

Typically, cybercriminals use means such as social media to gather data from their victims, such as names, roles, interests, and email addresses. 

Then, this information is used to create a false message on behalf of a trusted entity, such as banks, the victim’s workplace, or the victim’s university.

In the messages, the user is asked to download malicious attachments or click on links to malicious websites in order to collect confidential information, which may include usernames, passwords, and bank details.

Some attackers use inappropriate fonts, logos, and layouts in phishing emails, making it easier to identify them as such, but cybercriminals are increasingly getting better at this, making their messages look authentic.

Top 7 Types of Phishing Attacks

Here are the top 7 types of phishing used by cybercriminals to manipulate their victims:

Deceptive Phishing

Deceptive Phishing is the most common among types of phishing. In it, attackers impersonate a legitimate entity to access their victims’ personal data or login credentials, using messages with threats and a sense of urgency to manipulate them.

Here are some common techniques used in Deceptive Phishing:

• Use of legitimate links in emails, including contact information of the organization they are impersonating;
• Combination of malicious and non-malicious codes to cheat Exchange Online Protection (EOP). It is possible, for example, to replicate the CSS and JavaScript of a tech company’s login page to steal users’ account credentials;
• Use of abbreviated URLs to deceive Secure Email Gateways (SEGs) and “time bombing” to redirect users to a phishing landing page;
• Change of an HTML attribute in brand logos to prevent email filters from detecting the theft of the company’s symbols;
• Emails with minimal content, often in image form, to avoid detection.

Spear Phishing

Spear Phishing is also among the types of phishing that use email, but this model is more targeted. In practice, hackers use open-source intelligence (OSINT) to gather publicly available company data. 

Then, they focus on specific users, using this information to make the victims believe the message is from someone within the organization, thus facilitating the accomplishment of their requests.

To identify Spear Phishing, one needs to be aware of unusual insider requests, shared drive links, and documents that require a user login ID and password.

Whaling

Whaling is also among the types of phishing that use OSINT. Known as Whale Phishing, Whale Fraud, or CEO Fraud, this type of attack consists of identifying the name of the organization’s CEO through social media or corporate website and sending a message posing as them and making requests to victims.

To identify this type of attack, one must pay attention to abnormal requests made by leaders who have never sent this type of message before, for example. Moreover, it is important to verify the message has not been sent to or via a personal email. 

Vishing

Vishing is voice phishing, which happens when a cybercriminal contacts their victims by phone to awaken their sense of urgency and make them respond to their requests.

To identify Vishing, it is valid to check if the phone number used is from an unusual or blocked location, if the time of the call coincides with a stressful event, such as a tax filing season, and if the personal data requested is unusual.

Smishing

Smishing is an evolution of Vishing, which is characterized by sending texts asking the user to take a certain action to change a delivery, such as clicking on a link that installs malware on their device.

One can spot it by going to the service website and checking the status of the delivery or by comparing the area code with their contact list.

Pharming

Pharming is among the most difficult types of phishing to identify. It consists of hijacking a Domain Name Server (DNS) and directing the user who enters the website address to a malicious domain.

To protect yourself against this type of attack, you need to look for websites that are HTTPS, not HTTP, and be aware of indications that the website is false, such as strange fonts, spelling errors, or incompatible colors.

Angler Phishing

Angler Phishing is a type of attack in which malicious users send notifications or messages in a social media app to convince their victims to perform certain actions.

In such cases, it is advisable to be careful about notifications that may have been added to a post with malicious links, direct messages from people who hardly use the app, and links to websites shared in direct messages.

Common Phishing Signs

Keeping an eye for signs is a way to protect yourself from the action of malicious attackers who use different types of phishing to manipulate their victims. The following are the main indications of this threat:

Emails Exploring a Sense of Urgency

Messages that stimulate immediate action through threats or another way of awakening a sense of urgency should be faced with suspicion. After all, in this context, the goal of hackers is to ensure their victims respond to their requests in a hurry, before they can even notice inconsistencies in the email received.

Inadequate Tone

An important feature of phishing is that messages can use inadequate language and tone. Therefore, if you receive a message from a friend with an overly formal tone, suspect.

Unusual Requests

Emails with unusual requests often consist of phishing attacks. In practice, the victim may receive a message asking them to perform an action normally performed by the IT department, for example.

Spelling and Grammar Mistakes

In general, organizations often set up spellchecking of their emails. Thus, it is important to pay attention to spelling and grammatical mistakes that may indicate a phishing attack.

Incompatible Web Addresses

Another way to detect phishing attacks is by comparing the sender’s address with previous communication, which may point to incompatibility.

To do this, simply hover over the link in an email before clicking on it to see its true destination.

Unexpected Requests

Often, cybercriminals use fake login pages associated with emails that appear to be legitimate. On these pages, they can request financial information, which should in no way be provided by users without them checking the website that allegedly sent the email.

Best Practices for Preventing Phishing Attacks

Here are some best practices to prevent different types of phishing:

Train Your Employees

Educating your employees is the first step you should take to prevent phishing attacks, after all, unprepared people are an easy target for malicious agents. Nevertheless, the training offered must go beyond the traditional approach and include recent and sophisticated threats.

Use Email Filters

Usually associated with spam, email filters go beyond this capability and indicate threats related to phishing attacks. In practice, using an email filter can prevent the user from receiving a large number of phishing emails.

Ensure Protection Against Malicious Websites

Knowing that organizations are filtering emails to prevent phishing, cybercriminals have been attacking website codes. 

So, you must install website alerts in browsers so that they point out possible risks to end users.

Limit Internet Access

Another way to reduce the risks associated with malicious websites is to create access control lists, which deny the connection to certain websites and applications to everyone who tries.

Require the Use of Multi-factor Authentication

One of the main goals of cybercriminals is to steal users’ credentials, a risk that can be reduced by using multi-factor authentication (MFA). 

In practice, this mechanism requires the user to use two or more items to authenticate themselves by combining something they know (such as a password), something they have (such as a token), and something associated with who they are (such as fingerprint or facial recognition).

Remove Fake Websites

You can count on solutions that monitor and eliminate counterfeit versions of your website. This way, you can prevent your employees and customers from clicking on malicious links.

Back Up Regularly

It is very common for phishing attacks to be associated with malware, including ransomware, which can impact the productivity of your business if you do not have a data backup program.
