Threat Actor Employs Hawkeye Malware with Multiple Infection Vectors

On July 13, 2017, the Phishing Defense Center reviewed a phishing campaign delivering Hawkeye, a stealthy keylogger, disguised as a quote from the Pakistani government’s employee housing society. Although actually a portable executable file [1], once downloaded, it masquerades its icon as a PDF. 

Threat Actors Leverage CVE 2017-0199 to Deliver Zeus Panda via Smoke Loader

Our Phishing Defense Center identified and responded to attacks leveraging a relatively new Microsoft Office vulnerability during the past few weeks. Last week, the PDC observed threat actors exploiting CVE 2017-0199 to deliver the Smoke Loader malware downloader which in turn was used to deliver the Zeus Panda botnet malware. These emails claim to deliver an invoice for an “outstanding balance” and trick the recipient to opening the attached file. In one instance, we have also seen the malicious attachment being delivered via URL.

SMILE – New PayPal Phish Has Victims Sending Them a Selfie

Phishing scams masquerading as PayPal are unfortunately commonplace. Most recently, the PhishMe Triage™ Managed Phishing Defense Center noticed a handful of campaigns using a new tactic for advanced PayPal credential phishing. The phishing website looks very authentic compared to off-the-shelf crimeware phishing kits, but also levels-up by asking for a photo of the victim holding their ID and credit card, presumably to create cryptocurrency accounts to launder money stolen from victims.

New Phishing Emails Deliver Malicious .ISO Files to Evade Detection

On May 22, 2017, PhishMe® received several emails with .ISO images as attachments via the Phishing Defense Center. ISO images are typically used as an archive format for the content of an optical disk and are often utilized as the installers for operating system. However, in this case, a threat actor leveraged this archive format as a means to deliver malware content to the recipients of their phishing email. Analysis of the attachments showed that this archive format was abused to deliver malicious AutoIT scripts hidden within a PE file that appears to be a Microsoft Office Document file, which creates a process called MSBuild.exe and caused it to act as a Remote Access Trojan. AutoIT is a BASIC-like scripting language designed for automating Windows GUI tasks and general scripting. Like any scripting or programming language, it can be used for malicious purposes.

FBI Announces That BEC Scam Losses Continue to Skyrocket, as Losses Exceed $3.1B

Financial losses from business email compromise (BEC) scams skyrocketed by 2,370% between January 2015 and December 2016, according to an FBI public service announcement released Thursday. The alarming statistic represents a sharp increase from the agency’s previous announcement, serving as a warning to users to stay vigilant in recognizing the threat.  

Tales from the Trenches: DocuSign® DELoader Phishing Attack

Over the past several days, the Phishing Defense Center identified and responded to several messages related to an ongoing phishing email campaign spoofing DocuSign to carry out an attack. These messages appear to be official DocuSign emails including links to review the document. Upon clicking the link, various malicious files are downloaded to the victim’s computer including the DELoader financial crimes malware.

Google Doc Phishing Attack Hits Fast and Hard

Google Doc Campaign Makes a Mark

In the process of managing phishing threats for our customers, our Phishing Defense Center and PhishMe Intelligence teams saw a flood of suspicious emails with subject line stating that someone has “has shared a document on Google Docs with you”, which contained a link to “Open in Docs”. The “Open in Docs” link goes to one of several URLs all within the https://accounts.google.com website.

April Sees Spikes in Geodo Botnet Trojan

Throughout April, our Phishing Defense Team observed an increase in malicious URLs that deliver the financial crimes and botnet trojan known as Geodo. These emails take a simple approach to social engineering, using just a sentence or two prompting the victim to click on a link to see a report or invoice that has been sent to them.

An example of a typical phishing email used in these attacks is shown below:

Following the malicious links will lead the victim to download a hostile JavaScript application or PDF document tasked with obtaining and executing Geodo malware. One common attribute of these messages is the use of the words “invoice” or “order” as a common substring in the subject lines.

Below are some examples of subject lines we have observed:

Emails containing malicious links providing the PDF documents used to deliver this malware have also been found to contain the word “attachment” somewhere within in the subject line.

When the victim executes the JavaScript application or opens the PDF document, scripting content is used to download and execute the Geodo malware sample. The list below contains a representative sampling of payload locations used to deliver Geodo:

Once the Geodo payload is in place on the victim’s computer, it will connect to the Geodo command and control infrastructure allowing the attacker to collect sensitive information from the infected machine.

Listed below are command and control hosts that have been observed during our analysis:

The core functionality of the Geodo trojan lies in its ability to collect sensitive information from infected machines and their users. Sophisticated browser-based information stealing functionality provided by Geodo includes form grabs and HTTPS man-in-the-middle attacks. Geodo also sports the ability to produce new sets of phishing emails, delivering itself to new potential victims.

Recommendation:

PhishMe cautions its customers to be wary of emails containing suspicious links or attachments. Specific to this sample, we recommend that customers be observant for unexpected emails that contain subject lines referring to invoices or attachments, and email bodies that ask you to visit a link to see an invoice or report. PhishMe Simulator customers may consider launching simulations that follow this style of attack to further train their users to detect and report suspicious emails.

Does your Incident Response Plan include Phishing?

It’s no secret that 90% of breaches start with a phishing attack. The question is: are you prepared to recognize phishing and respond to it? Many organizations are concerned with how much spam they receive and implement controls specific to spam. But you shouldn’t confuse preventing spam with responding to phishing attacks.

Wide-Spread Ursnif Campaign Goes Live

On April 5th, our Phishing Defense Center received a flurry of emails with subject line following a pattern of Lastname, firstname. Attached to each email was a password-protected .docx Word document with an embedded OLE package. In all cases the attachments were password protected to decrease the likelihood of detection by automated analysis tools. A password was provided to the victim in the body of the email which attempts to lure the victim into opening the malicious attachment and to increase the apparent legitimacy of the message.
