How Does PAM Help Protect Against Ransomware Attacks?

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.

Why do you need both IDS and IPS, or maybe the NGFW too?

I would like to straighten the defense of the web application by talking about Intrusion Detection and Prevention Systems (IDS and IPS) as the third member of this security trio defense: WAF, RASP, and IDPS. In the previous articles, I talked about security defense technology Runtime Application Self-Protection (RASP) and Web Application Firewall (WAF).

What are IDS and IPS?

 

Intrusion Detection Systems and Intrusion Prevention Systems are used to detect intrusions and, if the intrusion is detected, to protect from it.

First, I will focus on explaining the differences between the WAF, RASP, and IDPS.

 

What is the difference between WAF, RASP, and IDPS?

 

I have already explained in previous articles the difference between WAF and RASP. Still, I will introduce IDPS and show you exactly why a combination of this trio is the best security choice.

Summary: IDPS is used to detect intrusions and protect from them. WAF will detect and block attacks based on rules, patterns, algorithms, etc. RASP detects the application runtime behavior using algorithms.

 

Why is it best to use both IDS and IPS?

 

To better understand why it is important to use both systems, we need to know what each of them does and doesn’t do and how combining them gives more effective protection. Each of those systems has its own types, which will be explained below.

 

Location and Range

 

These two types of security systems operate in different locations and have different ranges.

Facts:

·   IDS works across the enterprise network in real-time by monitoring and analyzing network traffic.

·   IPS works in the same network location as a firewall by intercepting network traffic.

·   IPS can use IDS to expand the range of monitoring.

By knowing this and using both IDPS, you can cover more range.

 

Host-based IDS and IPS

 

There are a few types of IDS and IPS. I will mention them so you can know which one targets what, but there is plenty of online documentation for more information.

 

Host-based IDS (HIDS) is used for protecting individual devices. It is deployed at the endpoint level. It checks network traffic in and out of a device, and it can examine logs and running processes. HIDS protects only the host machine. It does not scan complete network data. Similar to this type, IPS has its own Host-based IPS (HIPS). HIPS is deployed on clients/servers, and it monitors the device level as well.

 

Network-based IDS and IPS

 

Network-based IDS (NIDS) works on monitoring the entire network. It looks out at every network device and analyzes all the traffic to and from those devices. On the other side, IPS has its own type, called Network-based IPS (NIPS), deployed within the network infrastructure. It monitors the complete network and, if needed, tries to protect it.

**NIDS and NIPS are very important to network forensics and incident response because they compare incoming traffic to malicious signatures and differentiate good traffic from suspicious traffic.

 

Wireless IPS

 

IPS also has Wireless IPS (WIPS) type that monitors radio waves (wireless LAN) for unauthorized access points, which you can use to automate wireless network scanning. Techtarget site provided ways of using WIPS in enterprise in this article. Check it out!

 

Protocol-based intrusion detection systems (PIDS) and Application protocol-based intrusion detection systems (APIDS)

 

Both protocol-based systems are the type of IDS. They both monitor traffic to and from devices. The only difference is that PIDS monitors one server and APIDS group of servers.

 

Network behavioral analysis (NBA)

 

Network behavioral analysis (NBA) is the type of IPS that looks for unexpected behavior within patterns of a network itself.

 

IDS and IPS modes

 

IDS is generally set to work in inline mode. As for IPS, it is set to work in the network behind the firewall. It can operate in both modes: as an end host or in inline mode.

 

Most used IDS/IPS tools in 2022

 

According to softwaretestinghelp.com, the list of most used IDS tools is this:

·   SolarWinds Security Event Manager

·   Bro

·   OSSEC

·   Snort

·   Suricata

·   Security Onion

·   Open WIPS-NG

·   Sagan

·   McAfee Network Security Platform

·   Palo Alto Networks

For more info regarding pricing, pros, cons and features of these tools checkout the softwaretestinghelp site.

Also, spiceworks.com provided the list of the most used IDPS tools:

·   AirMagnet Enterprise

·   Amazon Web Services (AWS) GuardDuty

·   Azure Firewall Premium IDPS

·   Blumira

·   Cisco Secure IPS (NGIPS)

·   Darktrace Enterprise Immune System

·   IBM Intrusion Detection and Prevention System (IDPS) Management

·   Meraki MX Advanced Security Edition

·   NSFocus Next-Generation Intrusion Prevention System

·   Snort

For more info regarding pricing, pros, cons and features of these tools check out the spiceworks site. This research will also help you choose the right IDPS solution based on these tools’ features.

 

What is Next-Generation Firewall (NGFW) or Unified Threat Management (UTM)?

 

There is a modern type of technology that combines IDS and IPS with firewalls called Next-Generation Firewall (NGFW) or Unified Threat Management (UTM).

NGFW includes:

·   Standard firewall features (packet filtering, stateful inspection, and VPN awareness)

·   Integrated Intrusion Prevention (IPS)

·   Application awareness of threats

·   Detect and block risky apps

·   Threat intelligence

·   Upgrading security features (such as future information feeds)

·   New techniques that help to address new security threats

Researchers for nomios site have gathered information and made a list of the top 5 vendors for NGFW in 2022. Also, they gave suggestions on what you should look for when choosing the right NGFW tool. Check it out!

 

Conclusion

 

You should combine IDS and IPS because of three things: response, protection, and impact. If you decide to use IDS, the testing will stop at the detection phase but using IPS based on settings and policy testing will also include the prevention. Because IPS reacts immediately, it gives a certain layer of protection aside from detecting malicious activity. However, there are false positives possible using IPS that will end up shutting your network.

Organizations often set up Integration Detection Systems to handle the logs and notifications/alerts, routers, firewalls, and servers to fight threats.

A better solution would be using a combination of IDPS and setting it up when planning security. In the future, when the organization grows and needs better protection, it will be possible to use IDS/IPS solutions for additional networks, servers, or devices.

Also, depending on the organization’s security needs and cost restrictions, NGFW can be a good choice too!

Chinese-speaking MirrorFace targeted a Japanese political party with espionage and credential-stealing malware ahead of elections, ESET Research uncovers

  • At the end of June 2022, MirrorFace launched Operation LiberalFace, which targeted Japanese political entities.
  • Spearphishing email messages containing the group’s flagship backdoor LODEINFO were sent to the targets.
  • LODEINFO was used to deliver additional malware, exfiltrate the victims’ credentials, and steal the victims’ documents and emails.
  • A previously undescribed credential stealer we have named MirrorStealer was used in Operation LiberalFace.
  • MirrorFace is a Chinese-speaking APT group targeting companies and organizations based in Japan.

 
BRATISLAVA, BRNO — December 14, 2022
— ESET researchers discovered a spearphishing campaign, launched in the weeks leading up to the Japanese House of Councillors elections in July 2022, by the APT group that ESET Research tracks as MirrorFace. The investigation into the campaign, which ESET Research has named Operation LiberalFace and which targeted Japanese political entities, revealed that the members of a specific Japanese political party were of particular focus in this campaign. The spearphishing email messages contained the group’s flagship backdoor LODEINFO, which was used to deliver additional malware, exfiltrate the victims’ credentials, and steal the victims’ documents and emails. MirrorFace is a Chinese-speaking threat actor with targets based in Japan.

Purporting to be a Japanese political party’s PR department, MirrorFace asked the email recipients to distribute the attached videos on their own social media profiles to further strengthen the party’s PR and to secure victory in the House of Councillors. Furthermore, the email provides clear instructions on the videos’ publication strategy. The email was purportedly sent on behalf of a prominent politician. All spearphishing messages contained a malicious attachment that upon execution deployed LODEINFO on the compromised machine. MirrorFace started the attack on June 29, 2022, ahead of the Japanese elections in July.

LODEINFO is a MirrorFace backdoor that is under continual development. Its functionality includes capturing screenshots, keylogging, killing processes, exfiltrating files, executing additional files, and encrypting defined files and folders. The attack used a previously undocumented credential stealer that ESET Research has named MirrorStealer. It is able to steal credentials from various applications, such as browsers and email clients.

“During the Operation LiberalFace investigation, we managed to uncover further MirrorFace tactics, techniques, and procedures, such as the deployment and utilization of additional malware and tools to collect and exfiltrate valuable data from victims. Moreover, our investigation revealed that the MirrorFace operators are somewhat careless, leaving traces and making various mistakes,” says ESET researcher Dominik Breitenbacher, who discovered the campaign.

MirrorFace is a Chinese-speaking threat actor targeting companies and organizations based in Japan. While there is some speculation that this threat actor might be related to APT10, ESET is unable to link it with any known APT group. Therefore, ESET is tracking it as a separate entity named MirrorFace. In particular, MirrorFace and LODEINFO, its proprietary malware used exclusively against targets in Japan, have been reported as targeting media, defense-related companies, think tanks, diplomatic organizations, and academic institutions. The goal of MirrorFace is espionage and exfiltration of files of interest.
