solarwinds fireeye report

In an update and white paper [PDF] released on Tuesday, FireEye warned that the hackers – which intelligence services and computer security outfits have concluded were state-sponsored Russians – had specifically targeted two groups of people: those with access to high-level information, and sysadmins. As for mitigation measures, FireEye suggests broadly: a review of all sysadmin accounts in particular to see if there are any “that have been configured or added to a specific service principal” and remove them, and then search for suspicious application credentials and remove them too. The victims have included government, consulting, technology, telecom and extractive entities in North America, Europe, Asia and the Middle East. In … Hackers, suspected to be part of an elite Russian group, took advantage of the vulnerability to implant malware, which then found its way into the systems of SolarWinds customers when they updated their software. This compromise involved a backdoor being distributed through an update to SolarWind’s Orion software product. Here's an overview of our use of cookies, similar technologies and SolarWinds recently filed an SEC report indicating that, while they have over 300,000 customers, fewer than 18,000 customers were running the trojanized version of the Orion software. If all blocklist and connectivity checks pass, the sample starts generating domains in a while loop via its DGA. 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). Malware response messages to send to the server are DEFLATE compressed and single-byte-XOR encoded, then split among the “Message” fields in the “steps” array. The security advisory, the SolarWinds twitter account and the emails sent to customer do not bother with attributions to FireEye. This should include blocking all Internet egress from SolarWinds servers. Not all objects in the “steps” array contribute to the malware message – the integer in the “Timestamp” field must have the 0x2 bit set to indicate that the contents of the “Message” field are used in the malware message. In the past week this has again burst into the headlines with the story of an attack on the firm FireEye using malware inserted into network management software provided to customers by the tech company SolarWinds. After a dormant period of up to two weeks, the malware will attempt to resolve a subdomain of avsvmcloud[.]com. Attempts to immediately trigger a system reboot. After gaining initial access, this group uses a variety of techniques to disguise their operations while they move laterally (Figure 2). 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. The attacker infrastructure leaks its configured hostname in RDP SSL certificates, which is identifiable in internet-wide scan data. These subdomains are concatenated with one of the following to create the hostname to resolve: Process name, service name, and driver path listings are obtained, and each value is hashed via the FNV-1a + XOR algorithm as described previously and checked against hardcoded blocklists. Also special thanks to Nick Carr, Christopher Glyer, and Ramin Nafisi from Microsoft. “When a credential that has been added to an application is used to login to Microsoft 365, it is recorded differently than an interactive user sign-in,” the paper notes. The sample continues to check this time threshold as it is run by a legitimate recurring background task. SolarWinds.Orion.Core.BusinessLayer.dll (b91ce2fa41029f6955bff20079468448) is a SolarWinds-signed plugin component of the Orion software framework that contains an obfuscated backdoor which communicates via HTTP to third party servers. Microsoft later admitted that its source code had been rifled through.. Matthew McWhirt, director at FireEye's Mandiant and co-author of its newly released report on the SolarWinds attackers, says his IR teams see an abundance of … This operation is performed as the sample later bit packs flags into this field and the initial value must be known in order to read out the bit flags. Organizations can use HX’s LogonTracker module to graph all logon activity and analyze systems displaying a one-to-many relationship between source systems and accounts. Tasks can also be monitored to watch for legitimate Windows tasks executing new or unknown binaries. The cyber espionage group has tampered with updates released by IT company SolarWinds, which provides its products to government agencies, military, and intelligence offices, two people familiar with the matter told the Reuters agency. They gained access to victims via trojanized updates to SolarWind’s Orion IT monitoring and management software. 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. In … In at least one instance the attackers deployed a previously unseen memory-only dropper we’ve dubbed TEARDROP to deploy Cobalt Strike BEACON. However, in real-world environments, this exercise is impractical for most organizations.”. “Detection of forged SAML tokens actively being used against an organization has proven to be difficult,” the white paper notes. In addition, SolarWinds has released additional mitigation and hardening instructions here. The sample retrieves a driver listing via the WMI query Select * From Win32_SystemDriver. Malicious URL Prediction, Emulation of Kernel Mode Rootkits With Speakeasy, Remediation and Hardening Strategies for Microsoft 365 to Defend Against UNC2452. Steal the Active Directory Federation Services (AD FS) token-signing certificate and use it to forge tokens for arbitrary users. CISA encourages affected organizations to read the SolarWinds and FireEye advisories for more information and FireEye’s GitHub page for detection countermeasures: Prior to following SolarWind’s recommendation to utilize Orion Platform release 2020.2.1 HF 1, which is currently available via the SolarWinds Customer Portal, organizations should consider preserving impacted devices and building new systems using the latest versions. All matched substrings in the response are filtered for non HEX characters, joined together, and HEX-decoded. But without FireEye … They gained access to victims via trojanized updates to SolarWind’s Orion IT monitoring and management software. and ensure you see relevant ads, by storing cookies on your device. The DNS A record of generated domains is checked against a hardcoded list of IP address blocks which control the malware’s behavior. FireEye is releasing signatures to detect this threat actor and supply chain attack in the wild. Arbitrary registry write from one of the supported hives. Write using append mode. To empower the community to detect this supply chain backdoor, we are publishing indicators and detections to help organizations identify this backdoor and this threat actor. FireEye also confirmed a trojanized version of SolarWinds Orion software was used to facilitate this theft. 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. We have found multiple hashes with this backdoor and we will post updates of those hashes. Subdomains are generated by concatenating a victim userId with a reversible encoding of the victims local machine domain name. The actors behind this campaign gained access to numerous public and private organizations around the world. This has already led to subsequent news reports of penetration into multiple parts of the U.S. Government. The backdoor’s behavior and network protocol blend in with legitimate SolarWinds activity, such as by masquerading as the Orion Improvement Program (OIP) protocol and storing reconnaissance results within plugin configuration files. Blocklisted services are stopped by setting their HKLM\SYSTEM\CurrentControlSet\services\\Start registry entries to value 4 for disabled. We are tracking the actors behind this campaign as UNC2452. ]com, .appsync-api.us-east-1[.]avsvmcloud[. The attacker likely utilizes the DGA subdomain to vary the DNS response to victims as a means to control the targeting of the malware. This actor prefers to maintain a light malware footprint, instead preferring legitimate credentials and remote access for access into a victim’s environment. Sets the delay time between main event loop executions Delay is in seconds, and varies random between [.9 * , 1.1 * ]. The list of stopped services is then bit-packed into the ReportWatcherPostpone key of the appSettings entry for the samples’ config file. Executive Summary: While investigating a recent attack on itself, security Provider FireEye Inc. discovered a backdoor in a solution provided to them by Texas based SolarWinds Inc. Once discovered FireEye proceeded to If SolarWinds infrastructure is not isolated, consider taking the following steps: Restrict scope of connectivity to endpoints from SolarWinds servers, especially those that would be considered Tier 0 / crown jewel assets. Profile the local system including hostname, username, OS version, MAC addresses, IP address, DHCP configuration, and domain information. The attacker primarily used only IP addresses originating from the same country as the victim, leveraging Virtual Private Servers. From a report: Together with the report, FireEye researchers have also released a free tool on GitHub named Azure AD Investigator that they say can help companies determine if the SolarWinds hackers (also known as UNC2452) used any … Oh no, you're thinking, yet another cookie pop-up. The wide-spread extent of the SolarWinds security hacks and the release of FireEye’s penetration tools is probably the most significant network security event since the WannaCry ransomware attack in 2017. The attackers were in the systems, undetected, for anywhere up to six months, giving them lots of time to snoop around as well as install hidden holes for future access. Originally published December 14, 2020. You can also change your choices at any time, by hitting the FireEye’s report comes after Reuters, the Washington Post, and Wall Street Journal reported on … On Sunday, December 13, 2020, FireEye released a blog detailing an alleged compromise to the company SolarWinds. If any blocklisted driver is seen the Update method exits and retries. The “steps” field contains a list of objects with the following keys: “Timestamp”, “Index”, “EventType”, “EventName”, “DurationMs”, “Succeeded”, and “Message”. FireEye has notified all entities we are aware of being affected. [1] The Cybersecurity and Infrastructure Security Agency (CISA) is aware of active exploitation of SolarWinds Orion Platform software versions 2019.4 HF 5 through 2020.2.1 HF 1, released between March 2020 and June 2020. The hack is so severe that it formed a significant part of the confirmation hearing for new national intelligence director nominee Avril Haines in Washington DC on Tuesday. The malware uses HTTP GET or HTTP POST requests. Once the update is installed, the malicious DLL will be loaded by the legitimate SolarWinds.BusinessLayerHost.exe or SolarWinds.BusinessLayerHostx64.exe (depending on system configuration). FireEye has discovered additional details about the SUNBURST backdoor since our initial publication on Dec. 13, 2020. 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. A summary and recommendations for mitigation of the recent SolarWinds Global Cyber Security Incident. On 14 December 2020, the ACSC issued an initial alert regarding potential compromise of the SolarWinds Orion software. The credentials used for lateral movement were always different from those used for remote access. This is the targeting of sysadmins. 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. Perform a HTTP request to the specified URL, parse the results and compare components against unknown hashed values. The report outlined the four “primary techniques” used by the hackers: PS... Symantec says it has identified Raindrop, malware used in the SolarWinds campaign to spread through victims' networks. SolarWinds.Orion.Core.BusinessLayer.dll is signed by SolarWinds, using the certificate with serial number 0f:e9:73:75:20:22:a6:06:ad:f2:a3:6e:34:5d:c0:ed. Apparently, FireEye informed SolarWinds before informing its own customers, for whom it provides network security services. The sample will delay for random intervals between the generation of domains; this interval may be any random value from the ranges 1 to 3 minutes, 30 to 120 minutes, or on error conditions up to 420 to 540 minutes (9 hours). This is economic warfare friends. The extracted message is single-byte XOR decoded using the first byte of the message, and this is then DEFLATE decompressed. SolarWinds has evidence that the attack on its update mechanism started as early as the fall of 2019. SolarWinds was the victim of a cyberattack to our systems that inserted a vulnerability (SUNBURST) within our Orion ® Platform software builds for versions 2019.4 HF 5, 2020.2 with no hotfix installed, and 2020.2 HF 1, which, if present and activated, could potentially allow an attacker to compromise the server on which the Orion products run. Delay for [1s, 2s] after writing is done. Restrict the scope of accounts that have local administrator privileged on SolarWinds servers. The SolarWinds advisory, the CISA emergency directive, and FireEye’s GitHub page contain additional information and countermeasures. If no arguments are provided returns just the PID and process name. FireEye, which last Sunday disclosed a compromise at network management software vendor SolarWinds that allowed an unknown attacker to … We measure how many people read us, The attackers were in the systems, undetected, for anywhere up to six … According to a SolarWinds report filed with the U.S. Securities and Exchange Commission (SEC), it was a DevOps security issue: “the vulnerability … was introduced as a result of a compromise of the Orion software build system and was not present in the source code repository of the Orion products.” Some entries in the service list if found on the system may affect the DGA algorithms behavior in terms of the values generated. If people say no to these cookies, we do not know how many people have visited and we cannot monitor performance. The malware masquerades its network traffic as the Orion Improvement Program (OIP) protocol and stores reconnaissance results within legitimate plugin configuration files allowing it to blend in with legitimate SolarWinds activity. (Note: IP Scan history often shows IPs switching between default (WIN-*) hostnames and victim’s hostnames) Cross-referencing the list of IPs identified in internet scan data with remote access logs may identify evidence of this actor in an environment. Starts a new process with the given file path and arguments. Last updated January 11, 2021. According to FireEye and Microsoft as well as other individuals in the intelligence sector, Russian hackers are suspected in this breach. Note, this is a proactive measure due to the scope of SolarWinds functionality, not based on investigative findings.

They routinely removed their tools, including removing backdoors once legitimate remote access was achieved. If the sample is attempting to send outbound data the content-type HTTP header will be set to "application/octet-stream" otherwise to "application/json". This campaign’s post compromise activity was conducted with a high regard for operational security, in many cases leveraging dedicated infrastructure per intrusion. There is likely to be a single account per IP address. After an initial dormant period of up to two weeks, it retrieves and executes commands, called “Jobs”, that include the ability to transfer and execute files, profile the system, and disable system services. This will uncover any single system authenticating to multiple systems with multiple accounts, a relatively uncommon occurrence during normal business operations. Russian Hackers Suspected. The C2 traffic to the malicious domains is designed to mimic normal SolarWinds API communications.
