The WEF’s proclaimed Cyberpandemic has begun: defense, power, water, finance, and our supply chain are all vulnerable to massive disruptions after FireEye & SolarWind have unleashed weapons of mass digital destruction AND unlocked the back doors … Subdomains are generated by concatenating a victim userId with a reversible encoding of the victims local machine domain name. They similarly manipulated scheduled tasks by updating an existing legitimate task to execute their tools and then returning the scheduled task to its original configuration. If any blocklisted driver is seen the Update method exits and retries. The sample retrieves a driver listing via the WMI query Select * From Win32_SystemDriver. Compute the MD5 of a file at a given path and return result as a HEX string. Some of these hashes have been brute force reversed as part of this analysis, showing that these routines are scanning for analysis tools and antivirus engine components.

The cybersecurity firm FireEye, who discovered the SolarWinds Supply Chain Attack, said that this almost seven-month-old cyber attack still remains in its early stage with no development in the analysis of the attack and tracing the intruder.This attack has massively and shockingly impacted the private and government sector of the US. This is economic warfare friends. Command data is spread across multiple strings that are disguised as GUID and HEX strings. SolarWinds has evidence that the attack on its update mechanism started as early as the fall of 2019. Multiple SUNBURST samples have been recovered, delivering different payloads.

Once discovered FireEye proceeded to The company was ordered to shut down all SolarWinds Orion products in accordance with the Emergency Directive 21-01. Backdoor an existing Microsoft 365 application by adding a new application or service principal credential in order to use the legitimate permissions assigned to the application, such as the ability to read email, send email as an arbitrary user, access user calendars, etc. We are maintaining surveillance of the news and forensic archives regarding the SUNBURST attack on FireEye, which resulted in the theft of its “Red Team” tools for identifying vulnerabilities. For the time being, the best way to support us is to become a member at SGTreport.TV or become a SubscribeStar Member The DNS A record of generated domains is checked against a hardcoded list of IP address blocks which control the malware’s behavior. Hackers believed to be operating on behalf of a foreign government have breached software provider SolarWinds and then deployed a malware-laced update for its Orion software to infect the networks of multiple US companies and government networks, US security firm FireEye said today. You can also change your choices at any time, by hitting the According to FireEye and Microsoft as well as other individuals in the intelligence sector, Russian hackers are suspected in this breach. Given a file path and a Base64 encoded string write the contents of the Base64 decoded string to the given file path. A JSON payload is present for all HTTP POST and PUT requests and contains the keys “userId”, “sessionId”, and “steps”. This presents a detection opportunity for defenders -- querying internet-wide scan data sources for an organization’s hostnames can uncover malicious IP addresses that may be masquerading as the organization. This hash value is calculated as the standard FNV-1A 64-bit hash with an additional XOR by 6605813339339102567 after computing the FNV-1A. Disturbingly, FireEye, as well as 18,000 other SolarWinds customers, would have downloaded the malicious Orion software update, which was actually cryptographically signed (i.e., vendor “verified” software) by SolarWinds between March (version 2019.4 HF 5) and June of 2020 (version 2020.2.1). ‘\Windows\SysWOW64\NetSetupSvc.dll’, Attacker Hostnames Match Victim Environment. They allow us to count visits and traffic sources so that we can measure and improve the performance of our sites. Defenders can examine logs for SMB sessions that show access to legitimate directories and follow a delete-create-execute-delete-create pattern in a short amount of time. All matched substrings in the response are filtered for non HEX characters, joined together, and HEX-decoded. Arbitrary registry write from one of the supported hives. The actors behind this campaign gained access to numerous public and private organizations around the world. Background. Steal the Active Directory Federation Services (AD FS) token-signing certificate and use it to forge tokens for arbitrary users. While FireEye, the U.S. Treasury, and National Telecommunications and Information Administration (NTIA) were the first to report a security breach, the breadth of SolarWinds’ customer base is an indicator that the breaches are seemingly the tip of the iceberg. This actor prefers to maintain a light malware footprint, instead preferring legitimate credentials and remote access for access into a victim’s environment. Next it checks that HKU\SOFTWARE\Microsoft\CTF exists, decodes an embedded payload using a custom rolling XOR algorithm and manually loads into memory an embedded payload using a custom PE-like file format. FireEye also warned that it looks as though the hackers prioritized government officials and software companies; the latter because they could provide future routes of attack into other networks.
