Chloe Chamberland is really a threat analyst and person in the Wordfence Threat Cleverness Group. She holds the next certifications: OSCP, OSWP, OSWE, Protection+, CySA+, PenTest+, CASP+, SSCP, Associate of (ISC)2, CEH, ECSA and eWPT. Several are innovative certifications which includes OSCP and OSWE which are usually 24 and 48 hour examinations respectively, that want hands-on hacking abilities to pass.

Chloe works full-period at Wordfence to recognize and invert engineer emerging threats facing WordPress. She works carefully with suppliers to remediate vulnerabilities they will have, develops firewall guidelines for Wordfence, and publishes her analysis here, after the affected software program has already been patched by owner.

In the item below, Chloe describes how danger analysts and the consider attribution. She describes the problems connected with attribution and whether attribution pays to. Chloe also discusses various kinds threat actors, and dives in to the SolarWinds hack and assigns probabilities to each sort of threat actor predicated on what we understand about the hack. It is possible to follow Chloe on Twitter @infosecchloe.

The SolarWinds Orion hack is among the the majority of sophisticated hacks we’ve seen in quite a long time, and arguably probably the most significant hacks in years. Needless to say, one of the primary questions for safety analysts is who’s responsible.

The procedure for identifying the threat actor in a security incident is known as attribution, once we are identifying what or whom caused an incident that occurs. There is frequently debate in the protection planet about attribution. Is understanding the risk actor helpful? Or could it be a needless distraction when a rigorous incident reaction is underway?

Within determining attribution, security specialists identify operational risks. To put it simply, a threat actor’s inspiration is critically essential when determining what section of a business reaches risk. If a business doesn’t understand the particular actors behind an assault, they are able to risk ineffective or even inefficient remediation.

Before we are able to determine attribution we have to understand what forms of threats you can find, and what they might be capable of. Once you know those basics it really is simpler to understand who could be accountable based upon the reality.

In this article, hopefully to identify typical threat actor classifications which means that your incident response preparing is informed, thorough and thoughtful.

Most Typical Threat Actor Classifications

Script Kiddies

Script Kiddies are the least skilled on the list of threat actor organizations. Their motivation is mainly egotistical and revolves around bragging legal rights. This threat actor team is known as script kiddies because they often blindly make use of scripts produced by other security scientists without understanding of how those scripts really work. They are able to also develop their very own scripts, however, they’ll likely be very easy and there could be an apparent insufficient sophistication in the scripts they create.

A common consequence of an attack you’ll see from the script kiddie may be the defacement of an internet site, that is altering the appearance of a niche site with a fresh “face.” Defacement pages generally contain taglines like “Hacked by XXX”, which highlights the truth that the principal motivation is bragging legal rights.

The key indicator a threat actor is really a script kiddie is they succeeded in preliminary intrusion and made several apparent changes, but there isn’t a lot evidence that the attack escalated beyond that preliminary point.

How might this relate with WordPress?

In WordPress, the script kiddie may try to hack into websites using pre-created exploits made to take advantage of identified plugin vulnerabilities, as well as develop their very own scripts since many WordPress vulnerabilities are pretty trivial to exploit. Another strike you may encounter from the script kiddie targeting WordPress installations is really a brute force assault because of its simplicity. As soon as they access your site with a successful brute push attack, they are able to easily deface the website and move ahead.


Insider Threats (Malicious or elsewhere)

An insider threat could possibly be the consequence of malicious intent, or just drop to human error. Whatever the result in, an insider danger is because someone in the company, such as a worker, who conducts an strike or triggers a safety incident. Insider threats could be sophisticated and will go undetected for a protracted time period if controls like work duty segregation, work rotation, and mandatory holidays are not set up. Insider threats may also be accidental, which explains why it is very important have proper security recognition training in place alongside security policies that workers must consent to.

A common consequence of an accidental insider threat might be a DoS attack because of simple misconfiguration of a bit of software. Another probability is that gain access to is granted to inner networks due to a worker dropping victim to a interpersonal engineering attack. The options listed below are endless.

While a good intentional and malicious insider risk could take many types it would likely bring about the exfiltration of delicate information over a period or modification of techniques for a few personal gain.

The key indicator a threat actor can be an insider is that there exists a clear level of understanding of how any inner systems work, or there’s forensic evidence that indicates that the incident occurred via inner access which could only be given by someone inside.

How might this relate with WordPress?

Within WordPress, you can face a good insider threat with the site’s developer. Maybe you’ve granted usage of your WordPress web site to a programmer and established a connection. This developer is doing work on your website for yrs, and you simply trust he does everything you ask. However, the complete period, they might have already been putting spam SEO links on your own site during each advancement project. This would be looked at an insider threat that’s altering the integrity of one’s site. It might easily go unnoticed because of the rely on between you and the programmer, however, it might have a significant effect on your WordPress web site over time.

Likewise, the developer might reduce corners by setting up pirated or “nulled” variations of premium plugins or even designs, which typically contain backdoors. If the programmer was unacquainted with the dangers, this might be considered a case of insider danger via human error.


Hacktivists

This can be an interesting threat group where their main motivation would be to spread awareness about political and social causes. These risk actors tend to be sophisticated and very skilled, but that’s not a necessity to certainly be a hacktivist. There’s typically no monetary advantage or personal obtain for hacktivists apart from pressing their agenda. You might already be familiar with probably the most widely known hacktivist groupings, Anonymous.

You will probably see hacktivists taking sites offline with DDoS (Distributed Denial of Service) attacks, defacing sites with political or even social messages, and “doxxing” individuals by leaking incriminating or even confidential information regarding them.

The key indicators a threat actor is really a hacktivist is that the outcomes of a security incident may actually push a social or political agenda.

How might this relate with WordPress?

It isn’t likely your WordPress site will undoubtedly be bought out by hacktivists, but hacktivists often focus on organizations which have websites working WordPress. As such, in the event that you operate any political sites it’s possible that your web site could be the focus on of a hacktivist.


Cybercriminals (Organized Criminal offense)

Cybercriminal threat actors are powered primarily by private gain that is typically monetary centered. They often have a comparatively high level of skill and try to stay anonymous since what they’re doing is highly unlawful. They could steal sensitive information hoping of offering it to the best bidder on the darkish web, sell or lease usage of botnets, or steal cash directly from the foundation.

You will probably see this kind of threat actor participating in illegal cyber activity which will provide them with some type of financial gain. A good example of this would be somebody exfiltrating passwords from a business and then later marketing the dump of passwords on the darkish web.

The key indicator a threat actor is really a cybercriminal is that there is apparently some financial benefit to the outcomes of the attack.

How might this relate with WordPress?

One of the main element motivators at the rear of hacking WordPress will be money, therefore it’s probably that a most the attacks you notice on your own WordPress site are usually from cybercriminals. We usually see infections where websites are usually redirected to pharmaceutical websites or injected with spam SEO that is likely a covered service.


APTs (Advanced Persistent Threat)

Advanced persistent threats will be the most advanced and advanced threat actor group there’s. They often times take their period with assaults hoping to stay undetected, and can take several additional actions to make sure persistence on a compromised reference. Generally, these threat actors are usually backed by nation-says which provide help and assistance to these organizations, helping them to stay stealthy, persistent, and prosperous within their goals.

Episodes from APTs often bring about espionage like their intent is normally to steal confidential information that might help the nation-states they’re backed by.

The key indicators a threat actor can be an APT are that the attack appears advanced in nature, there is a high degree of stealth to the hack, and there’s evidence that persistence was preserved over time.

How might this relate with WordPress?

You are not more likely to see APT groups targeting WordPress sites unless the website provides them a doorway that will permit them further access right into a restricted network.


What do we presently find out about the SolarWinds Orion Hack and SUNBURST malware?

Inside exploring who may have been the danger actor inside the SolarWinds Orion assault, there are some details that provide us a knowledge of the attacker’s motive. These facts can stage towards a possible risk actor.

What is definitely SolarWinds Orion?

SolarWinds Orion is really a network management system made to help make managing corporate networks a lot more seamless by centralizing with all your network infrastructure administration within a location. The program is created in a compiled vocabulary rendering it harder to carry out thorough code testimonials with each update. That is an essential distinction, since it means there could have been some degree of trust required to make use of SolarWinds Orion.

What perform we know concerning the targets?

We understand that the malicious copies of SolarWinds Orion were deployed to almost 18,000 clients. The data indicates that following the initial infection, just select clients were targeted for phase two of the strike which consisted of information exfiltration. This included govt agencies just like the Departments of Treasury, Condition, Commerce, Power and Homeland Security alongside companies like Cisco, Microsoft, Cox Communications, VMware and FireEye.

Microsoft also announced they notified a lot more than 40 clients whose networks were compromised in the next stage of the attackers scheme. This included 30 clients from america and also victims in 7 additional nations: Canada, Mexico, Belgium, Spain, UK, Israel, and UAE.

A recent record by FireEye, an established security research company, declared that the threat actor that gained usage of their techniques via SolarWinds targeted authorities agency details and proprietary tools. This means that that the attacker could have had fascination with government affairs and magic formula information and perhaps wanted to utilize this information to help expand infiltrate systems.

The Intrusion Vector: Where has been it planted?

Currently, we don’t have much information around the way the threat actors at first gained usage of SolarWinds infrastructure to include the malicious updates, nevertheless, we can say for certain that the intrusion vector for the organizations influenced by this attack was the malicious updates which were pushed away to customers sometime in between March 2020 and June 2020.

We make reference to this as a supply chain attack, that is the introduction of malware right into a trusted software application that organizations will probably use because of the trust placed inside the vendor.

We can speculate that the threat actors likely had an excellent diploma network access and took their period when building the malicious update. This is really an assault that took an extended amount of period to build up in order that it would move undetected. Addititionally there is evidence that signifies the attackers ran a dried out run by pressing out an revise sometime in 2019 – this means that that they acquired a means in and wished to verify that their methodology in proved helpful prior to any more developments and malicious up-dates.

Safety researcher Vinoth Kumar told Reuters that, this past year, he alerted the business that anyone could entry SolarWinds’ update server utilizing the password “Solarwinds123.” This FTP account may have made it easy for attackers to upload their malicious data files, maintain persistence on SolarWind’s systems, and additional pivot in to the entirety of SolarWinds’ growth techniques and build architecture. That is, however, speculative. We can not definitively identify this because the preliminary intrusion vector.

The Malware: So how exactly does it work?

The malware itself is quite clever. Following the malicious up-date had been pushed to a person, it waited dormant for 12-14 days prior to making its first exterior call. This is to evade any recognition within the first fourteen days that agencies might perform supervising and tests of the program update.

From that time, the malware would carry out some triage to find out who the mark was and whether it had been viable. This is likely to be able to prioritize who the attackers wished to target for phase two of their strike. If it detected any body’s defence mechanism and was struggling to turn off the defensive procedures, it could enable a killswitch and instruct the malware shell never to execute in order to avoid any recognition.

The Motive: What gets the attacker done?

As of the writing, it would appear that most attacks have already been tries to compromise the confidentiality of information by exfiltration. The assault was likely designed to gain information regarding targets and retrieve information, indicating that was an espionage-based strike. There is presently no indication that information accessibility or integrity has already been compromised.

Based on what we realize, what conclusions can all of us draw about attribution?

It will be safe to state that the SolarWinds hack was the effect of a group of people who had lots of time, sources, and knowledge with evading recognition. We can create a few hypotheses and assumptions concerning and also require been responsible in line with the evidence we’ve.

The motive theory: Exfiltrate sensitive information from important systems including government agencies and big corporations.

Had been it a Script Kiddie?

Our probability rating: 0/10
We can extremely confidently say that was not the task of a script kiddie. The campaign has a large amount of complexity and sophistication, with proof an extremely solid foundation of specialized knowledge, which is not really indicative of a script kiddie and their standard capabilities. Very little analysis is required to state that this is simply not the task of a script kiddie.

Has been it a Hacktivist?

Our probability rating: 3/10
There exists a very slight possibility this was the task of a hacktivist threat actor but, there’s currently simply no evidence to point that there was any kind of social or political motive. The attackers had been exfiltrating data, that could have possibly been useful for a cultural or political agenda since we don’t know just what data had been exfiltrated. Nevertheless, with that said, there did not really seem to be any public or political correlation to the info being exfiltrated

Had been it an Insider Threat?

Our probability rating: 5/10
At the moment we have no idea the way the threat actor(s) initially breached the SolarWinds Orion software program to introduce the backdoor. Because of the sophistication of the assault and the timeline we’ve, it really is plausible that there is somebody working on the within since there is clear proof that the danger actors knew the way the software and signing procedure worked for improvements.

With that said, however, the sophistication of the next phase of attacks indicates that was likely the task of several individuals, so although it is possible there is a malicious insider that helped complete the job, it cannot have been the task of an individual malicious insider.

It is also extremely hard that this was the consequence of an insider threat predicated on error, aside from general problems with the company’s security position.

Has been it a Cybercriminal?

Our probability rating: 7/10
It is extremely possible this is actually the work of the cybercriminal or band of cybercriminals. The info being exfiltrated in phase two could possibly be considered highly important and likely a primary target for several criminals attempting to make money. In addition, the risk actor employed various ways to try and evade recognition which shows that the actor experienced extremely criminal intent.

Had been it an APT (Sophisticated Persistent Threat)?

Our probability rating: 10/10
There’s significant evidence to point that this may be the function of an APT. Not merely does the data we’ve indicate this conclusion, but additionally several reputable businesses with firsthand information of the breach, like FireEye, have significant proof to aid this. The malware has been highly complex and made to evade detection that is consistent with the task of APTs.

In an job interview with Kevin Mandia, CEO of FireEye, this individual stated that “ the attackers create an infrastructure to strike FireEye that has been wholly special to attacking FireEye. That requires a large amount of maintenance. That requires a large amount of coordination. That’s a surgical procedure – not really a hack.“ Which means that after the initial phase of the compromise, that was the update that contains a backdoor, the attackers setup a whole clean infrastructure to assault and exfiltrate information from simply FireEye, one of the numerous organizations that has been targeted in the next stage of the strike. This takes substantial manpower and assets and signifies that the danger is highly sophisticated with plenty of resources to attain their goal, because they may have create clean infrastructure for every target within their second stage.

Furthermore, there are reviews that the attackers were generating SAML tokens in compromised systems to be able to maintain persistence, lateral motion, and exfiltrate information from compromised techniques.

APTs tend to be called nation-state risk actors because they are typically groupings backed by nation-claims and used to carry out espionage. Because of the evidence of the institutions that show up to possess been focused in the next stage of episodes, including large companies and federal firms, it’s highly most likely this was for the advantage of a nation-condition, which some believe could be China or Russia. Initial reviews by the Washington Write-up and the brand new York periods attributed the assault to Russian threat actor APT 29, or “Cozy Bear”, though it has not really been confirmed currently, December 24 2020.

Conclusion

In today’s write-up, we explored the various threat actor classifications and how these relate with WordPress users along with took the deeper dive into and also require been in charge of the SolarWinds Orion hack. With all the current evidence we have nowadays, the SolarWinds Orion hack had been likely the task of a sophisticated Persistent Threat (APT), nevertheless, without more proof we can’t definitively recognize a known APT. It’s possible that it had been China, Russia, or another advanced hacking team with espionage intentions. FireEye provides assigned this danger actor a designation of UNC2452.

WordPress site owners may not require defenses against nation-state APTs. Nevertheless, knowing the motives and forms of risk actors targeting WordPress websites can inform what activities you need to take if your website is under strike.

We hope we provided you with sufficient insight today to enable you to better understand and also require been in charge of this attack, in addition to how essential attribution is for just about any incident response planning or execution.
