The clean-lines pf F-Secure's main page is simple in its design. However, F-Secure AntiVirus is only for Windows, so if you have macOS, Android, or iOS devices, you will need to look elsewhere. So financially, you are getting much more for the cost.

However, F-Secure grants you the ability to install the application on three different computers, unlike antiviral software from Norton or Bitdefender, which only give you one license. The cost of $39.99 per year is fairly standard when compared to other antiviral programs. If you are looking for an antivirus security program that is easy to use without a lot of additions, F-Secure may be the best option for you. F-Secure provides a simple program that focuses on the key job of safeguarding your system against a wide range of malware, and in some cases, ransomware. To be clear, this is not a security suite like McAfee. $path = "\\.The Finnish security vendor, F-Secure has released an Antivirus that focuses solely on protecting you from a variety of malware types and some ransomware. F-Secure did not see any evidence of the execution of this script despite its creation on victim systems by the threat actor. Interestingly the file still had the hostname and domain from a previous intrusion of another victim by the group, which allowed F-Secure to notify that victim of the activity. In addition, the threat actor deployed a PowerShell script named “a.ps1” that had the capability to further enumerate hosts across the network.

F-Secure’s investigation uncovered a forensic artifact that suggests the threat actor was watching a YouTube video on how to use this tool prior to execution.Īfter initial reconnaissance, the adversary executed a Base64 encoded PowerShell command. The scanner was downloaded from the software provider’s website via internet explorer and executed with explorer.exe. %USERPROFILE%\Downloads\Advanced_IP_Scanner_.exe The scanner was used to sweep multiple sub-networks for normal service ports and dynamic ranges.

Shortly after this they scanned the network using a portable version of Advanced IP Scanner, a tool popular in crimeware circles. C:\Windows\System32\net.exe group "enterprise admins" /domainĬ:\Windows\System32\net.exe user /domainĬ:\Windows\System32\net.exe group "domain admins" /domainĬ:\Windows\System32\net.exe group "domain computers" /domain

With an interactive PowerShell session they used the Windows utilities like net.exe, ping.exe and nltest.exe. Once the RDP session had connected the threat actor immediately began to enumerate the victim domain and network. The threat actor entered the victim network via a Remote Desktop Protocol (RDP) connection using stolen credentials of an administrator account belonging to that third-party IT service provider. The threat actor was able to extract credentials from this device and then access a host with connectivity to the victim network. The intrusion began in a third-party IT service provider, which had an un-patched VPN appliance that was vulnerable to remote exploitation. A detection section is included, which contains actionable takeaways so that organizations can improve their own defenses against this, and similar, threats.

This blog shall provide insight in to both the intrusion and the malware sample, so that organizations can be informed to protect themselves from this evolving threat. The sample was executed by a previously undocumented “wrapper”, which F-Secure’s research suggests has been used in combination with multiple malware families common in crimeware intrusions. F-Secure was also able to identify another recent intrusion conducted by the threat actor where they had deployed Ryuk ransomware.į-Secure’s analysis of the SystemBC sample identified that this was a new variant of the malware, with several notable differences from previous versions. The intrusion was stopped before the threat actor could reach their objective, but in recent reporting the use of this malware has been tied to Ransomware activity. In late February 2021, F-Secure’s Managed Detection and Response (MDR) service identified the execution of SystemBC malware as part of a hands on keyboard crimeware intrusion.
