One particular of the most efficient means for information technology (IT) gurus to uncover a company’s weaknesses in advance of the lousy guys do is penetration testing. By simulating genuine-environment cyberattacks, penetration tests, from time to time called pentests, delivers invaluable insights into an organization’s security posture, revealing weaknesses that could potentially guide to knowledge breaches or other security incidents.
Vonahi Security, the creators of vPenTest, an automatic network penetration tests platform, just unveiled their annual report, “The Top 10 Critical Pentest Results 2024.” In this report, Vonahi Security carried out in excess of 10,000 automatic network pentests, uncovering the best 10 inside network pentest results at above 1,200 businesses.
Let us dive into each of these critical findings to much better fully grasp the common exploitable vulnerabilities corporations face and how to tackle them effectively.
Top rated 10 Pentest Conclusions & Suggestions
1. Multicast DNS (MDNS) Spoofing
Multicast DNS (mDNS) is a protocol applied in modest networks to take care of DNS names without the need of a local DNS server. It sends queries to the regional subnet, enabling any process to react with the requested IP handle. This can be exploited by attackers who can reply with the IP deal with of their very own system.
Tips:
The most effective strategy for protecting against exploitation is to disable mDNS altogether if it is not currently being employed. Based on the implementation, this can be accomplished by disabling the Apple Bonjour or avahi-daemon provider
2. NetBIOS Title Service (NBNS) Spoofing
NetBIOS Title Support (NBNS) is a protocol utilized in interior networks to solve DNS names when a DNS server is unavailable. It broadcasts queries across the network, and any system can reply with the requested IP handle. This can be exploited by attackers who can reply with their very own system’s IP handle.
Suggestions:
The adhering to are some approaches for stopping the use of NBNS in a Windows natural environment or reducing the effects of NBNS Spoofing assaults:
- Configure the UseDnsOnlyForNameResolutions registry crucial in get to avert devices from working with NBNS queries (NetBIOS more than TCP/IP Configuration Parameters). Set the registry DWORD to
- Disable the NetBIOS service for all Windows hosts in the inside network. This can be completed via DHCP alternatives, network adapter settings, or a registry critical
3. Hyperlink-community Multicast Name Resolution (LLMNR) Spoofing
Website link-Regional Multicast Identify Resolution (LLMNR) is a protocol utilised in interior networks to solve DNS names when a DNS server is unavailable. It broadcasts queries across the network, making it possible for any process to answer with the asked for IP handle. This can be exploited by attackers who can reply with their personal system’s IP handle.
Tips:
The most effective technique for protecting against exploitation is to configure the Multicast Title Resolution registry critical in buy to reduce techniques from applying LLMNR queries.
- Applying Team Coverage: Laptop ConfigurationAdministrative TemplatesNetworkDNS Shopper Convert off Multicast Name Resolution = Enabled (To administer a Windows 2003 DC, use the Remote Server Administration Tools for Windows 7)
- Using the Registry for Windows Vista/7/10 Dwelling Version only: HKEY_Neighborhood_MACHINESOFTWAREPoliciesMicrosoft Windows NTDNSClient EnableMulticast
4. IPV6 DNS Spoofing
IPv6 DNS spoofing takes place when a rogue DHCPv6 server is deployed on a network. Given that Windows units choose IPv6 in excess of IPv4, IPv6-enabled purchasers will use the DHCPv6 server if accessible. For the duration of an attack, an IPv6 DNS server is assigned to these consumers, whilst they hold their IPv4 configurations. This allows the attacker to intercept DNS requests by reconfiguring consumers to use the attacker’s program as the DNS server.
Suggestions:
Disable IPv6 except if it is necessary for small business functions. As disabling IPv6 could likely induce an interruption in network services, it is strongly suggested to check this configuration prior to mass deployment. An alternative alternative would be to put into action DHCPv6 guard on network switches. In essence, DHCPv6 guard makes certain that only an authorized listing of DHCP servers are allowed to assign leases to purchasers
5. Out-of-date Microsoft Windows Programs
An outdated Microsoft Windows process is vulnerable to assaults as it no more time gets security updates. This helps make it an uncomplicated concentrate on for attackers, who can exploit its weaknesses and possibly pivot to other units and assets in the network.
Tips:
Switch out-of-date versions of Microsoft Windows with running methods that are up-to-day and supported by the company.
6. IPMI Authentication Bypass
Intelligent System Management Interface (IPMI) enables administrators to take care of servers centrally. On the other hand, some servers have vulnerabilities that permit attackers bypass authentication and extract password hashes. If the password is default or weak, attackers can get hold of the cleartext password and gain remote access.
Tips:
Considering that there is no patch obtainable for this individual vulnerability, it is suggested to accomplish one particular or far more of the next actions.
- Prohibit IPMI access to a minimal variety of units – methods which have to have entry for administration reasons.
- Disable the IPMI provider if it is not needed for company functions.
- Transform the default administrator password to 1 that is potent and advanced.
- Only use protected protocols, these types of as HTTPS and SSH, on the support to limit the odds of an attacker from properly acquiring this password in a man-in-the-middle attack.
7. Microsoft Windows RCE (BlueKeep)
Devices vulnerable to CVE-2019-0708 (BlueKeep) were being discovered all through testing. This Microsoft Windows vulnerability is hugely exploitable because of to obtainable resources and code, allowing for attackers to obtain whole manage over influenced systems.

On top of that, the corporation need to consider its patch administration program to decide the reason for the deficiency of security updates. As this vulnerability is a typically exploited vulnerability and could end result in important access, it must be remediated right away.
8. Neighborhood Administrator Password Reuse
In the course of the inside penetration check, several devices were located to share the similar area administrator password. Compromising just one local administrator account supplied accessibility to various systems, noticeably growing the risk of a popular compromise in just the business.
Recommendations:
Use a alternative these kinds of as Microsoft Regional Administrator Password Remedy (LDAPS) to make certain that the community administrator password across many systems are not reliable.
9. Microsoft Windows RCE (EternalBlue)
Methods susceptible to MS17-010 (EternalBlue) have been recognized for the duration of testing. This Windows vulnerability is highly exploitable due to offered resources and code, permitting attackers to get whole command in excess of influenced systems.
