Microsoft recently announced the discovery of a threat actor attempting to exploit SolarWinds Serv-U software, a secure FTP server organisations use for remote file access and management. This clearly indicates the increasingly sophisticated tactics mentioned actors are using to target organisations and gain unauthorised access to sensitive data. As the attacks become more widespread and sophisticated, it is important to understand more about the SolarWinds Serv-U software and its potential threats to organisations.
Background on SolarWinds Serv-U Software
SolarWinds Software is a software company that produces network performance monitoring and IT management solutions. SolarWinds Serv-U software is their secure, easy-to-use file transfer server and managed file transfer (MFT) solution designed specifically for organisations managing business requirements around transferring files.
For businesses, Serv-U enables users to quickly and securely upload, download, and synchronise digital data from anywhere on the web, from any device. The software utilises digital certificates to digitally sign data files for authentication purposes during digital file transfers. It also provides access control with directory browsing capabilities allowing multiple users to take advantage of Serv-U’s benefits without having to log in each time they use it.
Serv-U has numerous enterprise features including support for FTPS/SFTP/HTTP protocols while increasing governance over the transmission of sensitive files. Other features include web or desktop client access support via HTML5 or Windows native applications provided with the installation package, exposing programs as web services that can be accessed remotely using standard HTTPS authentication methods. Additionally, to safeguard against malicious attacks and malware threats, Serv-U includes integrated anti-virus scanning which automatically checks every file before the server receives it.
Microsoft Discovers Threat Actor Targeting SolarWinds Serv-U Software
Microsoft recently reported that a malicious threat actor targeted SolarWinds Serv-U software with a new attack campaign. According to Microsoft, this threat actor uses sophisticated techniques to gain access to Serv-U systems and deploy malicious payloads. Microsoft is actively investigating the issue to identify the attacker and get them to stop their malicious activities. Let’s take a closer look at Microsoft’s discovery.
Microsoft’s Security Team Discovers Threat Actor Targeting SolarWinds Serv-U Software
Microsoft’s security team has discovered a malicious threat actor targeting SolarWinds Serv-U FTP software. The nation-state sponsored attackers were seen trying to use this software to gain access and control of a customers’ environment.
The attack vector used was a malicious file downloaded from the attacker’s page to gather system information, such as installed applications and network traffic data. The file would also inject additional code into vulnerable systems, giving the attackers full control of the victim’s environment.
Microsoft issued an alert warning their customers and partners that the attacker had full code execution capabilities on compromised machines, noting that “The discovery shows that attackers have gotten increasingly sophisticated in their efforts to break into corporate networks using tactics such as trojanized open source products, backdoors, and an increased focus on obfuscation techniques.”
It is believed that the attack was likely speculation based on recent SolarWinds updates rather than any actual exploitation of vulnerabilities in the product itself.
However, Microsoft advised customers concerned they may have been affected: regular patching of serv-u installations; ensuring access controls are correctly managed; implementation of network segmentation policies; regular review of systems logging for unusual activity; and deployment endpoint protection solutions. Customers should also consider adding additional detection controls by setting up host-based intrusion detection or behaviour monitoring solutions as appropriate for their environment.
Impact of The Attack
Microsoft recently announced the discovery of a threat actor targeting SolarWinds Serv-U software. The attack used two vulnerabilities to gain access and spread across an organisation’s network. This has caused significant disruption for organisations using the SolarWinds Serv-U software, from data theft to ransomware attacks. In this article, we will discuss the impact of this attack on organisations using the SolarWinds software.
Potential Risks and Damage Caused by The Attack
The impact of the SolarWinds Serv-U software attack could be far-reaching and devastating. The attack appears to be focused on targeting government and private organisations, with potential risks and ramifications that are both immediate and long-term.
The potential risks posed by the attack range from immediate damage to networks and hardware to long-term data access and operations monitoring. On a short-term basis, attackers may gain unauthorised access to sensitive information such as usernames, passwords, account information, or the ability to manipulate existing data. Additionally, using stolen credentials can result in further exploits such as malware injection or phishing attacks Trojan of files onto company networks or data exfiltration stealing confidential information or intellectual theft.
The long-term dangers are equally concerning because the attackers have had time to set up surveillance within targeted systems for monitoring purposes or for creating backdoors for future access. Additionally, this type of cyberattack could have both direct and indirect repercussions on an organisation due to brand exposure associated with the incident and resulting losses in customer confidence. Finally, in extreme cases where a malicious actor has gained system control deeply, they may leverage the compromised access point towards other intrusions under the veil of authorised activity. As such, organisations should proceed cautiously when considering any further security responses following an intrusion event due their unknown scope implications.
Initial Response
Microsoft recently uncovered a malicious threat actor targeting SolarWinds Serv-U software. This malicious threat actor allegedly used multiple zero-day vulnerabilities to exploit the software. This finding has raised serious security concerns and Microsoft is currently taking steps to mitigate the potential risk to its customers. In this section, we will discuss the initial response from Microsoft to this security breach.
Microsoft’s Initial Response to The Attack
On December 17, 2020, Microsoft released its initial response to the SolarWinds Serv-U software breach. The company’s Security Response Center (MSRC) is “working closely with our external partners and other organisations such as CISA and the FBI to better understand potential implications related to this reported attack.”
Microsoft used several defence-in-depth techniques to detect and rapidly respond to advanced threats. For example, it has implemented several machine learning models and analytical techniques capable of detecting abnormal behaviour indicating malicious activity. Additionally, Microsoft has deployed a suite of countermeasures, known as mitigations, which can prevent security risks posed by stolen credentials from malicious actors.
Microsoft also announced that in response to the attack it is taking steps with immediate effect such as accelerating patching of on-premises Windows servers, deploying detection rules for auditing systems affected by SolarWinds Serv-U Software, setting active blocking rules for intrusive activity originating from suspicious URLs; offering guidance for identity monitoring services for customers who may be impacted; sharing public threat intelligence via its Threat Intelligence Center; and increasing active defences across Microsoft Azure cloud infrastructure coverings all regions where the company hosts customers.
Further Response
Microsoft recently discovered a threat actor targeting SolarWinds Serv-U software. The consequences of this attack include the potential leakage of sensitive customer data and disruptions to business operations. In response, Microsoft is taking measures to further analyse the attack and ensure all customer data remains secure. This article will dive into these measures and how they strengthen customer protection.
Microsoft’s Further Response to The Attack
In response to the breach, Microsoft has released a security advisory providing customers with additional guidance and mitigation steps, including disabling Telnet, further hardening Web browsing policies for outbound connections, and disabling unauthorised outbound connections. Additionally, Microsoft recommends that SolarWinds customers ensure that all system updates are regularly installed to help protect against zero-day attacks and supply chain compromises. System security is also recommended by requesting confirmation of any account changes. Organisations should also immediately report any issues found through the Attack Investigation Response service of their Security Operations Center (SOC).
It is critical for organisations using SolarWinds Serv-U software to download, install and configure all applicable patches as soon as they are available to protect themselves against this threat actor. Furthermore, it is highly recommended that organisations conduct an internal review of their present security posture and take necessary steps to protect their networks.
Additionally, users should reinforce best practices in their internal processes such as regularly patching vulnerable systems, monitoring for potential malicious activity both internally and externally on the network, validating integrity of system binaries/artefacts running on each node visited by privileged users/service accounts regularly, etc., to mitigate the risk associated with these types of supply-chain attacks.
Conclusion
Microsoft recently discovered a threat actor targeting SolarWinds Serv-U software, a popular file transfer protocol (FTP) server. This malicious actor was found to be exploiting vulnerable FTP servers to gain access to corporate networks. This article will discuss the findings in more detail and what it means for businesses using SolarWinds Serv-U software.

Summary of The Attack and Its Potential Implications
The SolarWinds attack marks a troubling new chapter in the world of cyber security. The potential implications are both significant and far-reaching. It is highly likely that the attackers could gain access to customer networks through their SolarWinds Serv-U software platform, and have now had time to gather sensitive data from vulnerable machines. As such, this attack presents a huge risk for organisations worldwide as stolen information can be used in various malicious ways.
In addition, given the sophistication of this type of threat actor, it is highly likely that other systems were also impacted by this attack and will continue to be targeted by malicious actors unless organisations take proper precautions. Organisations must therefore assess their current cyber security posture and upgrade their systems with the most up-to-date patches and protocols to minimise the chances of being targeted by similar actors in the future. Although an exhaustive review cannot guarantee 100% protection against future attacks, it can help to reduce digital exposure and identify key areas of vulnerability within any system or organisation.
