Threat Actor Utilizes COVID-19 Uncertainty to Target Users

By Kyle Duncan, Cofense Phishing Defense Center

As the world continues to contend with a tenacious pandemic, many employers are obliged to revisit medical-benefit policies. The Cofense Phishing Defense Center (PDC) has observed a new phishing campaign that aims to harvest Microsoft login credentials by posing as a company-wide sick/medical leave policy update.  

Figure 1-2: Email Body 

The sender’s email address is spoofed to appear as though the email is originating from the company’s SharePoint services by using the format “Sharepoint@[companyname].com“. However, one look into the email’s header information shows that this is not the case and that the email originated from outside of the organization, potentially from a compromised account operated by the threat actor. 

The email body itself is put together well and, at a glance, appears as though it could be legitimate. It even contains little details such as “This link will only work for anyone at [company name]” and “Microsoft OneDrive for [user’s email].” The threat actor has spoofed a legitimate Microsoft notification to appear legitimateusing a format the recipient would quickly trust at first glance. Since the file being shared refers to the company’s approach on sick leave during COVID-19, users are naturally going to be curious about what their company is doing for them. 

The glaring flaw with the email body is where it references both Microsoft OneDrive and SharePoint. Since the spoofed email address is attempting to trick the user into thinking this is a shared SharePoint file, it does not make sense for the email body to reference both of these services. It thus raises suspicion. The button users are intended to click also references OneDrive and, hovering over it, it reveals that the domain of the destination (oraclecloud[.]com) has nothing to do with Microsoft. It is apparent that this is not what it claims to be. 

Upon visiting the malicious URL, users are taken to a fake Microsoft login page as shown in Figure 3.  

Figure 3: Phishing Page 

The email address field of the login is automatically populated with the user’s email so they would only have to include their password. The page even includes the company’s logo to more effectively pass the login off as legitimate. Once the credentials have been secured, the user is then redirected to a page containing COVID-19 documentation, as seen in Figure 4, that seemingly appears relevant to what was mentioned in the email. While many phishing attempts redirect the user to a legitimate login page, the use of this document instead is another attempt to prevent the realization that the user’s credentials were just stolen.

Document Sharing Services Represent a Vector for Phishing Campaigns

By Zachary Bailey, Cofense Phishing Defense Center

The Cofense Phishing Defense Center (PDC) has seen the rise of threat actors impersonating common document-sharing services to harvest credentials. These attacks can also use legitimate services to host malicious documents that are delivered to an unsuspecting employee who trusts the domain where they are hosted 

Some of these attacks do not need to spoof the sender, such as this Adobe phish (Figure 1) that was found in a Proofpoint environment. The email appears merely to include a purchase order with encryption via the Adobe Document Cloud. In the email, Adobe is just one of several components of the phish. It builds credibility by posing as a government agency and suggests that the recipient can sign into Adobe to decrypt the file – or download Acrobat Reader to view it instead.

Figure 1: Email Body 

This email appears to be a forwarded message, as though the recipient is expecting it – FW: Purchase Order 3500250780 as the subject, which also includes the name of the organization sending the PO. A common tactic used by threat actors is to create a fake reply chain by inserting “RE” or “FW” into the subject line to trick the recipient into thinking it is a response to a conversation they initiated or were involved in.  

Even though the address is clearly from a Gmail domain, it is not an uncommon practice for work-related emails to be shared between personal and corporate accounts.  

The email is rather informativelisting the correct postal address and contact information for the government office it is impersonating. As mentioned earlier, the email body says, “To read it you sign into Adobe Document Cloud or download the latest Adobe Acrobat Reader.” Recipients are not urged to sign in but are presented an alternative option that would not put their credentials at risk. The only urgency is regarding “with immediate effect please ensure all invoices are addressed as below”, but that is legitimate information regarding how to address the invoice.   

If the recipient chooses to sign into the Adobe Document Cloud, they will immediately open the document which then launches in their default web browser. This HTML file will pull its resources from Adobe’s website while the pop-up message in Figure 2 delays the victim from seeing the page. JavaScript is embedded in the page to enforce basic password guidelines, which increases the odds that a realistic password is entered into the form. After the user attempts to log on, the HTML file will also send out a POST request with their login information to the threat actor.

Figure 2: Step 1 of Attack 

When the document is inspected by the recipient, its contents are not immediately known. A popup message will cover up the assets being loaded in, which will be read before proceeding. This is not hosted on a website, so checking the URL will not immediately tip off users that something is amiss. To them, they are just viewing a file on their computer. The wording of the popup is “This document is electronically encrypted to the receiver’s email”, which is a strange way of saying that the document can only be unlocked by the recipient. If a user is not familiar with technical terms, it could still sound legitimate to them, but that should be the first hint something is amiss. The second part of the popup urges them to sign in with “authenticated email credentials”, an even more noticeable tip off that this form wants their login information.  

Figure 3: Step 2 of Attack 

After the user clicks through to access the login page, a full webpage appears that looks like the Adobe Document Cloud site. This is still occurring inside of the downloaded document, and the only way to analyze where the form is from – without pressing “sign in” – is to inspect the code itself. To verify where the login information is going, we pulled up the network traffic and sent a request through. Our information is now going to “infiniteworks[.]net/IDI/high.php”, which is not a part of Adobe.  

Figure 4: Final Redirect of Phish  

After exposing their Adobe account credentials to the attacker, the victim is redirected to a new webpage. If they check the URL again, they will discover that they are now in the actual Adobe website. With no new document being unencrypted, they should be fully aware that something is wrong. They should alert their security team immediately

Variants of Emotet Malware

By Ala Dabat and Adam Martin 

The Cofense Phishing Defense Center (PDC) team has seen a resurgence in the number of Emotet variants in the past few months, with the majority of payloads being delivered via highly obfuscated macros embedded within Microsoft word documents.  

We will be taking a look at an example of Emotet that has managed to bypass Office365 SEGs using simple email layouts with a limited number of red flags usually picked up by traditional spam filtering.  

Figure 1 

A common pattern being observed has involved the number of payload deliveries bypassing traditional security scanning methods through both compressing and password protecting folders containing the malicious file. This makes it impossible for security scan engines to examine folder content. 

Figure 2

Once the password protected file is decompressed the malicious Emotet payload is presented, ready for the target to open. 

Figure 3 

Figure 4 

A calltoaction command is then executed (usually using PowerShell) via heavily obfuscated macros. 

Figure 5 

The call to action then downloads up to several variants of both Emotet and other malware families from a number of different commandandcontrol operations, which is in stark contrast to earlier generations of Emotet malware. Emotet appears to have the capability of exploiting known Windows system vulnerabilities, as well as having the ability to scan Windows directories in order to harvest sensitive data.  

Figure 6 

Following on from the contacted URLs displayed in the above figure, some testing was carried out on payloads downloaded. The URL found iFigure 7 was used as a hosting service for the Emotet sample. This is illustrated by the executable downloaded to the host machine.  

Figure 7 

Once executed, this malicious binary will delete itself from the original folder it was downloaded to, and will terminate its running processes. Then it will create a carbon copy of itself in “/AppData/Local/XBAuthManagerProxy under the name “security.exe.” A comparison of both the original SHA256 and the newly created file confirms they are identical.  

Figure 8 

Dynamic analysis of the dropped executable reveals a host of interesting functions being created and called. Native Windows DLLs associated with networking are utilized for connectivity seen in Figures 9 & 10.

A network traffic analysis confirms that information was posted to the aforementioned C2 address.

Business Email Compromise (BEC) Scam Advances Alert About Fraud

By Kian Mahdavi and Geraint Williams, Cofense Phishing Defense Center 

The Cofense Phishing Defense Center (PDC) is seeing continued growth in business email compromises (BECs)This is fueled by government grants that have recently been set in place and, as a result, enable SMBs to access finance faster than usual, particularly during the coronavirus pandemic.  

Quite often such attacks tend to target senior executives within organizations, typically due to the authority they have in getting employees to quickly respond to the request. This is completed by using a combination of social engineering tactics, such as urgency to forward confidential data and fear of work suspension (should the employee not do as instructed).

Figure 1  Body of email showcasing interaction  

The email body within Figure 1 reads: “Please get this information, followed by display name of an executive at a global financial firm, with the spoofed emailThis itself may raise red flags to eagle-eyed recipients as the company’s trademarked name is not included in any part of the full email address. Solid social engineering tactics have been utilized, with the attacker providing support to assist with the success of this attack – “can be found on any documents from HMRC …”

The attacker has spoofed law firm located in  North CarolinaSince the TLD is from a legitimate source, not only does it pass basic email security checks, such as SPF, but more importantly it evades existing security measures protected by Microsoft 365 EOP and Proofpoint.  

Furthermore, the opening of the email directly addresses the recipient by first name, as opposed to a generic opening such as, “Good Morning” or “Dear…”, indicating that this is a spear-phishing email that has been hand selected to target one individual.  

Figure 2 – Email header analysis 

If we dive further into the headers as shown above in Figure 2the “reply to” address is actually{redacted}@chckl[.]co[.]uk. chckl – a purchased top-level domain – in an attempt to draw full attention to the innocent law firm. This further provides evidence that the law firm may have had its email servers compromised. In this way, the attacker is filtering out their actual location.   

Typically, such emails target employees within financial departments, simply because of the data they can access. This particular attack does exactly that by harvesting the necessary sensitive information to be used for financial crime.

One can understand how easy it is to fall for such attacks, particularly for individuals who would expect to receive such emails. Attackers are using this to their advantage.

At the User’s Expense: Threat Actors Weaponize Companies’ Employee Reimbursements During the Pandemic

By Harsh Patel, Cofense Phishing Defense Center 

With the health crisis that is COVID-19, employees are dutifully working from home. While some already had home offices decked out with dual monitors, printers and the like to complete their jobs, others did not. Because of this many companies took to offering their employees a chance to buy the tools needed for their newly designated remote positions through added reimbursements. 

The Cofense Phishing Defense Center (PDC) has identified a campaign that attempts to steal employee credentials by leveraging reimbursement emails. This campaign was seen across multiple employee groups in the insurance, medical, professional services and banking industries.

Figures 1 and 2: Email Body 

The first thing the recipient will notice is the nickname field displays their company’s name. This will make it appear as if the email originated from within the company to put the recipient at ease about its legitimacy. However, the real sender can be seen right next to it. In this case, it was sent from a compromised account. The “Expense Reimbursement” subject also indicates conversation that would happen between a user and finance to further help with the credibility.

The email body continues to explain the reason for this email, and mentions an attached file with expense reimbursement certification, list of qualified employees and attached reimbursement policy. Although there is no attached file, the email contains a button “CLICK HERE TO REVIEW” with a hyperlink to take the recipient to the phishing landing page.

Figure 3: Phishing Page 

Upon clicking the button found in the email, users are redirected to the page shown in Figure 3. At a glance, it appears to be a login page for Adobe, offering the user options to view, download or send. Note that the email of the recipient is already filled out; the only field left empty is for the password. Despite all these attempts to appear legitimate, this is not the real Adobe login page. The URL in the address bar is not Adobe.com and this isn’t the typical Adobe login users would normally see or receive 

However, should users continue to enter login details, they are redirected to their company’s site as if nothing happened. And that is exactly what threat actors want. These pointless redirects to legitimate documents or company sites have become increasingly common as a way to distract users from the series of spoofed pages and/or actions they have just taken.

Coronavirus Test Results Return Data-Exfiltrating Ransomware

By Dylan Duncan

Cofense Intelligence has discovered COVID-19-themed phishing campaign that delivers a new version of the Hentai OniChan ransomwareThe new variant, known as King Engine, exfiltrates data and charges a significantly higher ransom than previously analyzed versions of Hentai OniChan. Previous campaigns delivering the Berserker variant of this ransomware used similar phishing emails to target the financial and energy sectors and did not exfiltrate data. Ransomware campaigns that exfiltrate data are becoming more of a common trend as they add to the pressure of paying ransom and reduce the efficacy of file backups. 

The phishing email shown in Figure 1 was found in environments protected by secure email gateways (SEGs) and currently targets the healthcare industry using response subjects allegedly returning patients COVID-19 test results. The spike in coronavirus cases during October has led to more testing and makes this type of phishing campaign even more threatening. This campaign uses common tactics, techniques, and procedures (TTPs) to reach end users and deliver Hentai OniChan ransomware that belongs to the Quimera ransomware family. Though, of course, the addition of data exfiltration, almost certainly to support data leaks should a targeted victim refuse to pay the ransom, is new. This addition highlights a new trend seen in ransomware that is similar to the Avaddon ransomware campaign that was first seen in June and was delivered by the Trik botnet.  

Figure 1  Phishing Email Delivering Hentai OniChan Ransomware. 

Hentai OniChan Ransomware 

Campaigns observed by Cofense that deliver the Hentai OniChan ransomware date back to September and have been found in environments protected by Proofpoint, Symantec, TrendMicro, Microsoft ATP and Cisco IronPort. These campaigns use a common tactic to reach end users by delivering embedded URLs to download an HTML or PDF file. The downloaded files contain components to drop and run the ransomware executable encrypting victims and holding them hostage, promising to provide a decryption application upon receipt of the ransom payment. Once the target’s files are encrypted, a ransom note is provided and a background image, shown in Figure 2, is set explaining the means by which the encrypted user may pay the ransom and regain access to the encrypted data. The ransom note explains to victims affected how to pay the ransom and includes a price, Bitcoin address, timeline and contact email address.

Figure 2  Hentai OniChon Ransom Note 

Berserker v. King Engine 

More ransomware operations have added to the chaos by using data exfiltration. This campaign shows Hentai OniChan has joined the trend.The early stages of the Hentai OniChan ransomware that used the Berserker version did not exfiltrate data, and encrypted files with the .HOR extension. The new strain, King Engine, as of now, has only been seen targeting the healthcare industry and exfiltrates data to an email address found within the ransomware executable. This version encrypts files with a .docm extension and charges a significantly higher ransom of 50 Bitcoin (BTC) (~$650,000 USD), whereas the previous version only charged 10 BTC (~$130,000 USD). Based on our analysis, other ransomware threat actors who have followed the data exfiltration trends often set up data leak websites to publish stolen data if the ransom is not paid. Aof now, data leak websites have not been seen by Hentai OniChan operators
