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.

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.
