Trend: Credphish Links Stuffed in Benign Attachments Are on the Rise

By Kian Mahdavi, Cofense Phishing Defense Center

While it’s true that most enterprise-directed phishing is credential phishing, that doesn’t mean attackers have completely abandoned attachments. The days of malware-laden attachments are dwindling. You’re not going to find dangerous embedded macro or .VBS in 2020 at the same frequency observed in 2016. Attackers are using attachments, more now than ever, to deliver embedded URLs. Why? Because secure email gateway (SEG) vendors have emphasized auto-scanning and wrapping URLs in the body of emails.

During the last few weeks, the Cofense Phishing Defense Center (PDC) has observed a significant uptick in credphish URLs stuffed in attachments successfully bypassing several commercial SEGs. The attachment types are varied, but many are commonly used in normal business communications – .DOC .HTML, .HTM, .XLSX, .PDF, etc. Check out our REAL phishing threats samples here for a complete list.

If you think stuffing credphish URLs in attachments to sidestep automated URL scanning is a no-brainer for attackers, we agree. You’d be surprised at the number of SOAR vendors demoing automated-phishing-analysis playbooks that fail due to this simple attacker adaptation. This phenomenon isn’t going to slow down.

Here’s a common example of a campaign reported to the PDC by a vigilant user:

Figure 1: Email Body

There has been a recent rash – 500 variants – of this campaign reported from our users via the Cofense Reporter Button. The campaign originated from an assumed compromised account from a legitimate business. Originating from a legitimate business surely added to a sense of legitimacy. Luckily, the recipient asked themselves: “Am I expecting to receive a document from this sender?”

Upon opening the attached .XLSX document, Microsoft Excel loads, prompting the user to click an embedded image using “trusted” brands to spruce up the legitimacy of the ruse. Once clicked, the attack redirects to the phishing landing page requesting the user’s credentials.

Figure 2 – The underlying “Open” link doesn’t take the victim to OneDrive

Once credentials have been supplied, the phishing website redirects the user to the authentic “office[.]com” to make the victim feel like the whole experience was legit.

Figure 3 – Phishing landing page 

Figure 4  Redirect to authentic office[.]com webpage 

Figure 5 below displays the HTML source code with POST command when a user types in their credentials and attempts to login. In fact, their personal data gets forwarded to the attacker via a pre-configured PHP script.    

Figure 5 – POST command forwards users’ credentials to the above URL 

Slipping credential phish URLs into innocuous attachments is going to frustrate SEGs for years to come because of the endless file formats that support HTML, compounded by all the clever ways attackers can obfuscate those URLs from automated analysis. Cofense customers avoided a disaster because of their commitment to upgrading their wetware.

sample phish spoofs salesforce to deliver credential phishing link

Phish Found in Proofpoint-Protected Environments – Week Ending September 27, 2020

100% of the phish seen by the Cofense Phishing Defense Center (PDC) have been found in environments protected by Secure Email Gateways (SEGs), were reported by humans, and automatically analyzed and dispositioned by Cofense Triage.

Cofense solutions enable organizations to identify, analyze, and quarantine email threats in minutes.

Are phishing emails evading your Proofpoint Secure Email Gateway? The following are examples of phishing emails seen by the PDC in environments protected by Proofpoint. This week we see a plethora of links – most of them using trusted services – reach customer inboxes. When technology is unable to block phish because of the risk of blocking legitimate emails, it’s well-trained users that detect and report threats.

sample phish spoofs the irs to deliver a link to buer loader

TYPE: Malware – Buer Loader

DESCRIPTION: This phish uses the element of surprise and urgency with a tax theme to lure the recipient into clicking the link. The link looks trustworthy, since it’s hosted in Google Docs. It leads, however, to an install of the Buer Loader. Cofense has been writing about the use of Google Docs in phishing attacks since 2017.

sample phish uses a payment theme to deliver a link to credential theft

TYPE: Credential Theft

DESCRIPTION: Leveraging a finance theme, this phish uses trustworthy Microsoft OneDrive URLs. Okay, so they’re not quite trustworthy, since they’ll lead the recipient to a Microsoft OneNote document that redirects to a credential harvesting site. Where did you want to go today?

sample phish uses a shipment theme to deliver a link to netwire rat

TYPE: Malware – NetWire RAT

DESCRIPTION: Spoofing a logisitics company, this phish promises shipping information but hides malicious links behind innocent-looking images. Clicking the link leads the recipient to install GuLoader, which installs the NetWire Remote Access Trojan.

sample phish delivers a google doc link to buer loader that installs bazarbackdoor

TYPE: Malware – Buer Loader

DESCRIPTION: If you’re thinking this phish looks awfully familiar, it’s not you. Aside from the change to an employee termination theme, this attacks leverages the exact same tactic as our first example – a Google Docs-hosted threat. In this case, the Buer Loader goes on to install the BazarBackdoor malware. These attacks should get you all fired up.

sample phish delivers xlsx attachment leading to agent tesla keylogger

TYPE: Malware – Agent Tesla

DESCRIPTION: Using a purchase theme, this phish offers to place an order for seafood but delivers a malicious Microsoft Excel spreadsheet with a CVE-2017-0199 to CVE-2017-11882 download chain to the Agent Tesla Keylogger. I wonder if they wanted that seafood shipped COD?

sample phish delivers credential phishing link using a document theme

TYPE: Credential Theft

DESCRIPTION: Spoofing a healthcare organization, this document-themed phish delivers a link to a credential harvesting site. Although redacted to protect the innocent, this sample used a very legitimate-looking message with signature block and legal disclaimer.

sample phish spoofs salesforce to deliver credential phishing link

TYPE: Credential Theft

DESCRIPTION: This phish uses urgency and the trappings of a popular SAAS platform to lure the recipient into clicking the link. In this case, the links lead to a credential harvesting site. Although not a panacea, Multi Factor Authentication (MFA) is still an effective way to protect your organization.

Malicious emails continue to reach user inboxes, increasing the risk of account compromise, data breach, and ransomware attack. The same patterns and techniques are used week after week.

Recommendations

Cofense recommends that organizations train their personnel to identify and empower them to report these suspicious emails. Cofense PhishMe customers should use SEG Miss templates to raise awareness of these attacks. Organizations should also invest in Cofense Triage and Cofense Vision to quickly analyze and quarantine the phishing attacks that evade Secure Email Gateways.

101 Credential Phishing for Observant Employees

By Luis Raul Parra, Cofense Phishing Defense Center

Asome point in your (digital) life you have received annoying notifications about unexpected signin attempts to one of your accounts/services, and you have ignored them. After all, it was just an attempt – no one was able to access anything. Yet, if you are vigilant enough, you would report this unauthorized attempt to the service provider and contribute to enhancing security. Well done! But keep reading; this article is for you.  

The Cofense Phishing Defense Center (PDC) has observed a new phishing campaign that aims to harvest Office365 (O365) credentials of “vigilant” users who want to act on unrecognized sign-in attempts to their accounts.  

The campaign was reported by users in several companies across Englishspeaking countries including the United States, England and Scotland. The message was carefully crafted to pass as a real alert of an unexpected sign-in on the recipient’s corporate account. It urged immediate action. 

Figure 1: Email Body

All reported emails used the same technique to customize the attack: The “From” field contained the address “postmaster@COMPANYDOMAIN.cpasurveys.com” in order to convince the end user that this was a valid alert notification from their company’s email security system.  

Figure 2: Email Header

The subject of the email states that there was a sign-in attempt to the user’s account from an unrecognized device, specifying the name of the user and claiming to come from “COMPANYNAME Mail Service”. The content of the body states the timestamp, location, IP address and device where the (false) attempt was performed. In all cases, the IP address shown in the body was 194[.]209[.]77[.]62.  

To make the email even more credible, the attackers included a confirmation code stated to be valid for 24 hours with aims of pressuring the recipient to act within that time. They were thoughtful enough to add the message “if this was you, you’re all set!” 

Furthermore, there was the option to click on the “Unsubscribe” button in order to stop receiving future messages like these. The URL behind a link of the type hxxps://tracking[.]mail[.]netflix[.]tshirtsintaramerica[.]com/click/* is possibly just a tracker that then redirected to the official company website.

The credential phishing attempt was done through an HTML file attached to the email. Images and CSS styles were pulled from a different website: hxxps://youmustlast[.]website/wassets/: 

Figure 3: CSS Style 

The HTML file already contained the user’s email address in the email account address field: 

Figure 4: Phishing Page

Should the recipient enter the corporate credentials into the attached HTML page, a POST action sends the username and password to the threat actor and the URL hxxps://sharepreview[.]site/win/next[.]php

Figure 5: POST Action

Credential phishing done. At the same time, you’ve been made to feel vigilant at having spotted something untoward happening with your account. That’s how the attackers attempt to trip up alert and conscientious users.

You Can Respond to Phishing Threats in Seconds with Cofense and Cyware: Here’s How

Targeted and relentless. Threat actors pinpoint organizations to steal credentials, infect endpoints, encrypt data for ransom, or exfiltrate intellectual property or non-public information.

All organizations will be phished, but they don’t have to experience a reputation-damaging breach. The best defense is a combination of aware employees, purpose-built phishing solutions, automated incident analysis and response playbooks, and a repeatable process that scales as fast as attackers innovate.

Cofense and Cyware have partnered to provide organizations with the resources to collect phish that evade secure email gateways (SEGs), automate the analysis, and determine threat severity in seconds.

The security workflow is preceded by conditioning employees to recognize suspicious email and report to their security team. What happens next is a blend of technology and intelligent analysts who have the right information to make an informed decision without negatively impacting the business.

The use case is simple, and the process is effective:

  • Phish evade the SEG
  • Employees report the suspicious email
  • Cofense TriageTM ingests and analyzes one or more email clusters with similar tactics
  • Cyware CSOL (security orchestration platform) ingests indicators from Cofense Triage
  • Cyware CTIX (threat intelligence platform) enriches indicators from Cofense Triage with Cofense IntelligenceTM and other premium intelligence sources
  • Cyware CSOL runs a complete response playbook which may include blocking a URL at the network gateway to protect employees from reaching the external phishing site

Let’s look at the sequence of events and how the response is carried out.

  1. Phisher crafts their email (figure 1) and in this case is attempting to direct the employee to a malicious site where a payload could infect the endpoint.

Figure 1. Malicious link within a company-wide email portraying to be from HR

2. A conditioned employee reports the email that evaded the SEG to a predetermined abuse mailbox monitored by the SOC. Purpose-built Cofense Triage ingests all emails from the abuse mailbox and automatically analyzes to quickly remove benign reports while at the same time highlight real threats.

Figure 2. Reported email ingested into Cofense Triage for automated analysis

3. Upon ingestion into Cofense Triage, out-of-box phishing rules are applied, and automated analysis categorizes the email as ‘advanced threats’, matching Emotet indicators and tactics. Benign emails are not impairing the view and the SOC can focus on credible phishing threats from a highly reputable reporter (in this case, a VP within the company).

Figure 3. Processed email matching advanced threats Emotet rules

4. Knowing this email is dangerous, the URL is designated malicious by an analyst

Figure 4. SOC analyst verifying malicious threat indicator

5. Additional validation within Cofense Intelligence further confirms the URL is malicious and delivers analysts related phishing indicators that, in this example, are part of the Emotet malware family. Other domains, files, and URLs are returned from knowing just one threat indicator.

Figure 5. Cofense Intelligence JSON output snippet with additional threat indicators

6. Once Cofense has confirmed that the URL is malicious, the analyst can leverage the orchestration capabilities of the Cyware Security Orchestration Layer (CSOL) to take action and begin remediation and triage efforts. CSOL gives users the ability to create automated, customizable workflows that easily integrate with the other tools in their security stack.

In this example, the analyst initiated the Cofense Triage Playbook to ingest the data it received from the Cofense Triage API. The playbook parsed the available data from Cofense to find the associated indicators, and then leveraged integrations with their other enrichment tools to fully enrich all associated indicators.

Figure 6. CSOL ingests Cofense Triage phishing data

7. Once enriched, the CSOL Playbook automated the mitigative action. The sender of the malicious email was automatically blocked at the email gateway and a confirmation notification was sent to the analyst.

Figure 7. CSOL runs through remediation to block sender at the email gateway

8. In addition, the malicious IOCs were sent to the SIEM to perform a historical lookup. If any of the malicious IOCs were previously seen in the organization’s environment, an alert was created and sent to the SOC team.

Figure 8. CSOL runs through additional steps from data received from Cofense

9. Finally, proactive defensive action was taken. The malicious URL was automatically blocked at the firewall, and all associated indicators were added to CTIX, Cyware’s Threat Intelligence Platform. Adding these indicators to CTIX ensures that this intelligence is memorialized and can be used at a later time for analytics, enrichment, and further correlation by the threat intel team.

End of Support for Windows 7 Means Beginning of Upgrade-Themed Phishing Campaigns

By Kaleb Kirk, Cofense Phishing Defense Center  

Over the last few years, businesses have been getting serious about updating their corporate desktop images. For quite some time, Windows 7 has been the predominant operating system (OS) for many workplaces and environmentsWindows 10 was released in 2015yet many companies are just now making the transition. With that comes the pains of upgrading end users machines. Standardizing a corporate desktop image is arduous with complicated edge cases that must be considered for all the hardware variants. The job is further complicated when thirdparty software has yet to officially support a new OS. This explains why enterprises wait, sometimes for years, before taking the plunge. Unfortunately, these delays give the bad guys time to refine exploitation techniques on older operating systems lacking the latest architecture.  

The phishing lure below preys on the victim’s anxiety about losing productivity while their computer is upgraded. Comically, the attacker uses a colorful list of benefits the end user receives to get them to take the baitWill we see an uptick in this phishing lure? It will depend on the success rate of this theme. Time will tell.   

Figure 1-2: Email Body

The subject references a Windows upgrade, but there is also something else manipulative: the inclusion of the “RE:” before the rest of the subject. Internal email about company meetings, news and IT upgrades are common. Prefixing the “RE:” may instill a sense of urgency by leading the user to believe they have missed a prior communication about the upgrade.

We look at phishing emails that bypass commercial gateways all day, every day. Most of them are hastily slapped together. This lure needs improvement, but it’s not completely awful. We give this threat actor two gold stars for the table with made-up laptops, fake serial numbers, building, etc. It applies a good sense-of-urgency ploy using the highlighted “Today,” and the body doesn’t have obvious grammar or spelling errors. Again, not completely awful.

How can this attacker upgrade this lure from a C- to a B+? This email would be more believable if the sender were more generic. “Helpdesk,” for example. We obfuscated the From: line of the compromised account  “Genadiy” which was not from the intended victim’s company domain, and certainly not from their IT department. The intended victim unfortunately doesn’t have a clean way to easily know the true underlying URL because it’s annoyingly masked by Proofpoint’s URL Defense (which, ironically, would not have defended the user because, once clicked, the phishing page loaded instantly).

Figure 3: Credential Phishing Page

Figure 3, above, shows the loaded credential phishing page. This page gets a D- for lack of effort. They wasted a valid SSL certificate on a terrible version of an OWA login page.

This phish closes out cleanly by redirecting the intended victim to a Microsoft page about the discontinued support of Windows 7 (but still leaves the target worried about their OS upgrade).

Figure 4: Final Redirect

Attackers have been using the “time to upgrade your out-of-date software” ploy for years. With Windows 7 ending official support, it won’t be surprising if we see a flurry of better versions of this phish in the future. Hopefully your vigilant users know that “Genadiy” (from a company that isn’t yours) doesn’t upgrade an operating system “Today,” and via email. Cheers.

sample phish spoofs sharepoint with a fax notification that will lead to a credential harvesting site

Phish Found in Proofpoint-Protected Environments – Week Ending September 20, 2020

100% of the phish seen by the Cofense Phishing Defense Center (PDC) have been found in environments protected by Secure Email Gateways (SEGs), were reported by humans, and automatically analyzed and dispositioned by Cofense Triage.

Cofense solutions enable organizations to identify, analyze, and quarantine email threats in minutes.

Are phishing emails evading your Proofpoint Secure Email Gateway? The following are examples of phishing emails seen by the PDC in environments protected by Proofpoint. This week we see examples that are part of complex polymorphic campaigns. They use varying tactics to confuse perimeter defenses and increase the workload on security teams. Without a powerful phishing analysis platform, chances are high that at least one of these attacks will succeed.

sample phish uses a document theme with either link or xls attachment to deliver trickbot

TYPE: Malware – TrickBot

DESCRIPTION: This first example comes in a couple of flavors – links and attachments. Both use a project theme to lure the recipient into accessing a macro-laden Microsoft Office spreadsheet to deliver TrickBot first and then BazarBackdoor.

sample phish uses invoice theme to deliver a link to hentai onichan ransomware

TYPE: Malware – Hentai OniChan

DESCRIPTION: Another example highlights the variations an attacker will use within the same campaign. This finance-themed phish delivers links to either directly, or via a .html file, download the Hentai OniChan ransomware.

sample phish uses a link to install a reconnaissance tool

TYPE: Malware – Reconnaissance Tool

DESCRIPTION: This campaign uses a mix of themes to deliver a reconnaissance tool. The example shown uses an illness theme, while others use a report theme. Either way, the result leaves us feeling a bit sickened.

sample phish uses a proposal theme to deliver links to a credential harvesting site

TYPE: Credential Theft

DESCRIPTION: Finally someone cares about security! This email promises a secure invitation and a business proposal. How can you resist? We recommend you keep from clicking the embedded links, since they lead to a credential harvesting site.

sample phish spoofs sharepoint with a fax notification that will lead to a credential harvesting site

TYPE: Credential Theft

DESCRIPTION: That’s an awfully legit-looking SharePoint logo you got there. That must mean the linked fax document is also legit. It’s not, of course, as the link will take the recipient to a site designed to steal credentials.

sample phish uses an invoice theme to deliver an encrypted doc attachment that will install trickbot

TYPE: Malware – TrickBot

DESCRIPTION: Shipping an invoice with a password is a sure sign it can be trusted, right? Must be really important. In this case, the most important thing is not to fall for the phish, as the attached Microsoft Office document uses macros to deliver a set of VBS scripts to install TrickBot.

sample phish with a purchase order theme uses a linked image to install nanocore remote access trojan

TYPE: Malware – NanoCore RAT

DESCRIPTION: This phish comes with all the charm of a truck stop breakfast diner. A friendly greeting and a nasty ending thanks to a link that leads to a NanoCore Remote Access Trojan installer. Better get the biscuit to go.

Malicious emails continue to reach user inboxes, increasing the risk of account compromise, data breach, and ransomware attack. The same patterns and techniques are used week after week.

Recommendations

Cofense recommends that organizations train their personnel to identify and empower them to report these suspicious emails. Cofense PhishMe customers should use SEG Miss templates to raise awareness of these attacks. Organizations should also invest in Cofense Triage and Cofense Vision to quickly analyze and quarantine the phishing attacks that evade Secure Email Gateways.

Virtual Submerge is off to a roaring start.

We just wrapped up the first day of our annual phishing event, Submerge, and to say it was a huge success is an understatement. Our shift to a virtual event enabled thousands of attendees to join from around the world, engaging in the sessions and demos with Cofense experts who were standing by to help answer questions, provide direction and assist through interactive chat.

Judging from attendee feedback, it was a very good day one. And it’s not too late to join us for day two.

Here are a few quick highlights from day one.

  • Keynote presentations. We were impressed – but not surprised – by the quantity and caliber of questions and comments we fielded as a result of the thought-provoking keynote sessions from our co-founders, Rohyt Belani, CEO, and Aaron Higbee, CTO. Thank you to our audience for your engagement throughout the day; we’re already looking forward to what day two has in store.
  • Breakout sessions. We sought to offer a well-rounded program, and many people enjoyed the added benefit of earning CPE credits as a result of our partnership with ICS2. Across all attendees, there were thousands of views for the breakout sessions. Our sincere thanks go out to all of our talented industry experts who put so much effort into the Virtual Submerge lineup. The quality was above and beyond.
  • Solutions Center demos. Cofense Triage and Cofense Vision, two of our innovative solutions for detecting and removing phish when they bypass your secure email gateway (SEG), were the Solutions Center darlings. SEGs, we see once again, are nowhere near as reliable, or promptly patched, as they should be. The demand remains intense for fast and effective incident response, with near-immediate quarantine capability.
  • Registrations. We were blown away by the number and range of registrants. They came from around the world and across industries from healthcare, government and financial to hospitality, transportation, manufacturing and more. It seems everyone – from the cybersecurity leaders to the threat intelligence analysts, awareness experts and incident responders – has experienced the pain of dealing with a phish that makes it into their environment.

Be sure to join us tomorrow to hear the keynote fireside chat with Dmitri Alperovitch, co-founder and former CTO of Crowdstrike, and Aaron Higbee. The session will be followed by a product keynote from Keith Ibarguen, Cofense chief product officer.

If you weren’t able to join us today, or haven’t registered, it’s not too late. Register now to view the exclusive Cofense Submerge content while it’s still available.

We are excited to have you with us for this first-ever virtual Submerge event.

sample phish uses a quote theme to deliver a pdf attachment with a link to azorult stealer

TYPE: Malware – AZORult Stealer

DESCRIPTION: This quotation-themed phish has all the pressure of a high stakes auction. It’s a lot of words – many of them impactful – in a short amount of space. Rather than raising their hand for an unintended bid, the recipient of this email clicked the Cofense Reporter button so our PDC could identify a malicious link in the attached PDF that led to the AZORult Stealer malware. Going once. Going twice. Gone!

sample phish uses a document theme to deliver a password-protected zip to install iced-id

TYPE: Malware – Iced-ID

DESCRIPTION: This phishing threat isn’t just cryptic, it’s encrypted! This response-themed attack delivers a password-protected .zip archive containing a macro-laden Microsoft Office document with a .hta downloader for Iced-ID. Opening this chilly attachment would have been a grave mistake.

sample phish uses an invoice-theme to deliver a malicious link leading to the wsh remote access trojan

TYPE: Malware – WSH Remote Access Trojan

DESCRIPTION: Many of us long for the days of unfettered travel and this email spoofs an aviation company with an invoice for a booked flight. It actually delivers a link to Google Drive that will download a VBS Loader to install the WSH Remote Access Trojan. Be careful what you wish for!

sample phish uses a response theme to deliver ursnif via embedded link on google docs

TYPE: Malware – Ursnif

DESCRIPTION: Skipping the friendly skies, there’s always the open road. And any decent road trip requires a sound insurance policy. This response-themed phish goes into considerable detail to convince the recipient to click the embedded links that will lead to a password-protected .zip archive containing VBS Droppers to run Ursnif. Our recipient appraised the offer and reported it to the security team.

sample phish uses a document theme to deliver a link to a credential harvesting site

TYPE: Credential Theft

DESCRIPTION: Un autre phish! Using a document theme, this simple attack uses Microsoft OneDrive links to host credential stealing web pages. Incroyable!

example phish with a bonus theme uses a .html attachment to install a reconnaissance tool

TYPE: Malware – Reconnaissance

DESCRIPTION: Just like the attackers, we’re throwing in this last phish as a bonus. A promise of money is often enough to lure a recipient into clicking. Had they opened the attached .html file, they would have been led to a macro-laden Microsoft Office document delivering a reconnaissance tool.

Malicious emails continue to reach user inboxes, increasing the risk of account compromise, data breach, and ransomware attack. The same patterns and techniques are used week after week.
