November 10, 2017 by Heather McCalley in Malware Analysis

Recently, PhishMe® recorded suspicious messages that spoofed bnm.gov.my, the domain for the central bank of Malaysia, Bank Negara. The emails concerned a Funds transfer. Figure 1  Initial phishing message Red Flags Right Away The spoofed sending address belongs to a U.S.-based employee account on a high-reputation .ORG domain.  (Red Flag number 1: The friendly portion of sender name does not match the email address.)  Addresses on .ORG and addresses on university (.EDU) domains are frequently used to bypass spam filters that are set to allow messages through only when they appear to be coming from a sending domain with a...

Viewing Phish with a Payload using PhishMe Intelligence and Maltego

November 2, 2017 by Cofense in Cyber Incident ResponseThreat Intelligence

BY MIKE SAURBAUGH AND GEOFF SINGER Visualize Phishing Relationships with PhishMe Intelligence™ and Maltego Fishing (without the “P”) is not a lot of fun when you just drop a line in the water and hope for the best. When fishermen want to see where the fish are, they look to the fish finder on the bridge to “look underwater” to find schools of fish. Similarly, when an analyst is looking to “catch” a phishing campaign, correlating the attacker’s campaigns and their payloads can benefit by being able to visually graph and link phishing threats. PhishMe Intelligence combined with Maltego can...

Don’t Go In the Attachment: 5 Security Reminders in Honor of Halloween

October 31, 2017 by Cofense in Internet Security AwarenessMalware Analysis

Do we really need another Halloween-themed security blog? Yep. We do. Not because our edgiest holiday triggers more cyber threats. No, Halloween season is scary because it’s been absorbed by the winter holidays—the spendiest, cyber-riskiest time on the retail calendar, beginning in mid-September and lasting until…it ends, right?

CTB-Locker: The Latest Crypto Malware Coming to you Via Email Spam

January 19, 2015 by Cofense in Malware Analysis

The latest crypto malware threat – CTB-Locker – promises to be one of the most serious security threats seen in recent years. The latest crypto malware is one of many of its ilk that have emerged in the past two years. This form of malware encrypts files on victims’ computers and will not unlock them until a ransom is paid. Only then will the key to decrypt data be provided. Crypto malware has been around for some time, although its popularity has been increasing over the past couple of years. One of the first major crypt malware variants was CryptoLocker....

January 16, 2015 by Cofense in Malware Analysis

Over the last few months, we’ve been tracking Dyre and reporting changes to the malware on this blog.  Dyre’s latest iteration shows  yet another shift in tactics – one that combines characteristics of Dyre with Upatre code to create a new downloader… Figures 1, 2, 3 and 4 shows three different emails, all with the same content but with different malicious links, which we we’ll use interchangeably in our examples.

Cridex Malware Authors Warn Lloyds users of Dyre

November 19, 2014 by Cofense in Malware Analysis

PhishMe malware researchers have been helping you protect your network by sharing information about the Dyre Trojan and Cridex malware on a daily basis for several months; however, in that time we have not seen any actions as bold as those used by the Cridex malware authors today. Dyre is the current top banking Trojan being distributed by email, and it poses a significant threat to businesses and consumers. The Trojan steals credentials and the attackers use that information for financial fraud. Threat Analyst Neera Desai let us know about this new threat from today’s Cridex attack, which uses a malicious Microsoft...

Three Ways Reporter Can Enhance Your Incident Response Process

November 18, 2014 by Cofense in Cyber Incident Response

Most of us have been in an airport and heard the announcement over the loud speaker; “If you see something, say something.”  The airport has security personnel; however, their agents cannot be everywhere at once.  They collectively rely on travelers passing through the airport to be their eyes and ears in places agents cannot be.  In this way, as an airport traveler, you are a “sensor” watching for, detecting, and alerting on suspicious behavior such as unoccupied luggage. What does this have to do with information security? Just as passengers can help prevent an incident in the airport by reporting...

Two Attacks… Two Dyres… All Infrastructure

November 6, 2014 by Cofense in Internet Security AwarenessThreat Intelligence

Over the last few days, we have seen two waves of Dyre. The attackers have changed things up a bit and made it harder to analyze. By using memory forensics techniques, we took a peek into their command and control (C2) infrastructure. The #1 rule of memory forensics…everything has to eventually be decoded, and we’re going to use this to our advantage. Here’s a quick look at the waves of emails we received. (Figures 1 and 2)

Bash Vulnerability CVE-2014-6271 – Worm-able and Possibly Worse Than Heartbleed

September 25, 2014 by Cofense in Internet Security AwarenessThreat Intelligence

Post Updated 9/30/2014 Several months ago, the Internet was put to a halt when the Heartbleed vulnerability was disclosed. Webservers, devices, and essentially anything running SSL were affected; as a result, attackers were able to collect passwords, free of charge. With Heartbleed, the exploit made a splash and many attackers started to use the vulnerability. One of the more high-profile attacks of Heartbleed was the CHS attack, where the attackers siphoned 4.5 million patient records by attacking a Juniper device, then hopping onto their VPN. So how can something be bigger than Heartbleed? I’m glad you asked.

Four Ways Phishing Has Evolved in 2014

August 20, 2014 by Cofense in Internet Security AwarenessThreat Intelligence

Phishing isn’t exactly a new kid on the block. Phishing is one of the most common email-based threats. It is a tried and tested tactic that continues to deliver impressive results for cybercriminals. That’s why phishing continues to grow in popularity. In the month of June 2014 alone, phishing activities totaled $400 million in losses, which could be annualized at $102 million per year. While it has been around for years, phishing has evolved considerably and has increased in efficiency and effectiveness. In the last six months (as compared to 2013), we’ve seen several differences in the type, size and...

Macro documents with XOR Encoded Payloads

November 9, 2015 by Cofense in Phishing

When reversing malware samples, one of the things that we as analysts look for are places where the attackers slip up. This can be anywhere from using the same strings, to weak obfuscation routines, or re-using the same snippet of code. When we talk about the attackers, there is this misconception that they are these super villains who can only do evil, but keep in mind they are humans too.

Awareness isn’t the goal, it’s just the beginning

October 27, 2015 by Aaron Higbee in Internet Security AwarenessMalware Analysis

When people refer to PhishMe as the awareness company, we smile and nod. I want to correct them, but the label ‘security awareness’ is comfortable and relatable. One of the activities that organizations commonly believe will help reduce risk is mandatory security awareness computer-based training (CBT) lessons.  The hope is that if we enroll our humans in online courses about how the bad guys hack us, they will walk away with a wealth of new-found awareness and avoid being victimized.  (Try to visualize how far in the back of my head my eyes are rolling…)

Business Email Compromise Phishing Attacks Soaring

September 30, 2015 by Cofense in Internet Security AwarenessPhishing

Business email compromise phishing attacks are soaring. The profits that can be made from these types of attacks have made them highly popular with cybercriminals. That should be of major concern for all business leaders. When people ask me “What’s going on with Phishing?” these days I tell them that 2015 will be remembered as the Year of the Email Phish.  Not Email Phish as in “someone sent me a link to a malicious website by email”, but rather Email Phish as in “the goal of this phishing attack is to steal my email password.”  During the calendar month of...

Vistaprint Abuse – Free Phish for All

September 24, 2015 by Cofense in Phishing

Over the last few months, we’ve been seeing a huge influx of attackers using VistaPrint for business email compromise (BEC) scams. Losses due to account takeovers total over a billion dollars, and given the nature of these wire fraud attempts, it’s pretty easy to get the money, unless you’re the VP of finance for PhishMe. Why are attackers using VistaPrint, and what makes them such a middle-man for these attacks?
