A Warning on Christmas Delivery Scams

The time of year has once again arrived when post offices are busier than the freeway on a Friday evening. We buy gifts, online and in stores, and we send and expect packages to and from the far corners of the country, continent, and even the world. Yet behind this frenzy of merriment skulk a series of dangers. Although Christmas is still more than a month away, scammers of this kind have already been active in various areas across the US. For a number of years, security experts have grown to expect a hike in the number of internet scams being...

Beware: Encryption Ransomware Varieties Pack an Extra Malware Punch

As the public becomes more and more aware of ransomware threats through journalistic outlets and the advice of security professionals, threat actors face more challenges in successfully monetizing the deployment of their tools. The longevity of ransomware as a viable criminal enterprise relies upon the continued innovation that ensures threat actors can deliver and monetize infected machines. Much of the innovation seen in 2016 was focused on defying the expectations for how ransomware is delivered such as steganographic embedding of ransomware binaries, other forms of file obfuscation, and requirements for command line argumentation. These were all put forward as ways...

Unscrupulous Locky Threat Actors Impersonate US Office of Personnel Management to Deliver Ransomware

Update 2016-11-11: It is important to PhishMe to avoid hyperbolic conclusions whenever possible. In the interest of clarifying some conclusions that have been drawn from this blog post, it is important to keep in mind the nature of Locky distribution and how this malware is delivered to victims. We consider it a serious responsibility to report on very real threats in a way that lends itself to our credibility as well that the credibility of all information security professionals. PhishMe has no reason to believe that this set of emails was delivered only to victims of the OPM incident nor...

The (BEC) Song Remains the Same

I had a dream, a crazy dream, that we stopped responding to ridiculous email messages demanding that a wire be sent immediately.  Also in that dream, all the bad guys were caught and had to pay restitution and go to jail. While that second part may never happen, there has been definite progress toward the dream goal and there are definite steps to take to ensure that you – and others in your company – do not fall victim to a BEC email. Coordinated by the National Cyber-Forensics & Training Alliance (NCFTA), contact information and incident details are being swapped quickly...

Behavioral Conditioning, Not Awareness, Is the Answer to Phishing

BY AARON HIGBEE AND SCOTT GREAUX You don’t stop phishing attacks by raising user awareness. A recent study conducted by a German university confirms what we at PhishMe have known all along: Focusing on awareness isn’t the point. The real solution is behavioral conditioning. The study, conducted by Friedrich-Alexander University (FAU) of Erlangen-Nuremberg, Germany, used 1,700 students to simulate spear phishing attacks. An August 31 Ars Technica article published preliminary results of the study showing at least 50% of students clicked simulated phishes, even though they understood the risks. With its headline, “So Much for Counter-phishing Training: Half of People...

Macro Based Anti-Analysis

Over the past several months PhishMe research has noticed an increase with Anti-Analysis techniques being included within Office macro and script files. This is the first post in a series where we look at the inclusion and effectiveness of these methods. Although the use of Anti-Analysis techniques is not new, they are generally observed within the packed payload in an effort to avoid detection by endpoint security solutions. Most recently we came across a campaign of emails which included a malicious Microsoft Word document. The document contains a standard lure using an image instructing the user to enable active content...

Cyber Crime: The Unreported Offense

On July 22, 2016 the UK’s Office for National Statistics released crime details for the year ending March 2016.  For the first time, this data included information about fraud and computer misuse offenses, which was compiled in the National Crime Survey for the first time in October 2015. While the police recorded 4.5 million offenses from March 2015 to March 2016, the survey indicates there were likely 3.8 million fraud instances and 2 million computer misuse instances during that same year, with the vast majority of these crimes being unreported to law enforcement.  The report has caused for a new call for additional...

Presidential Phishing Scams: Examining Voter Vulnerability

With emotions running high during election season, an email with the name Romney or Obama in the subject line could make even an experienced user click on a malicious link. Spammers are taking advantage of the Presidential election buzz and using malware-laden emails to target users. Many of these emails don’t have any visible consequences, so users may not even realize when malware is infiltrating their personal computers or mobile devices. But what about the potential danger this malware can bring into your workplace from these spear phishing scams?

Breaking the Myths of Social Engineering

Last week, a Washington Post article by Robert O’Harrow offered an interesting look at the most common attack vector used by cybercriminals to penetrate enterprises today: spear phishing. While we applaud (loudly) the thrust of the article – that enterprises need to educate users on the dangers of spear phishing – there are some very real challenges in user education that the article does not address.

Why PhishMe makes Pentesters Uncomfortable

I read Aitel’s article right before leaving for BlackHat: “Why you shouldn’t train employees for security awareness” Popcorn in hand, this should be a fun read. After all, we agree that traditional awareness methods don’t seem to be sticking.

LinkedIn password leak: What it means for phishing

Spoiler: LinkedIn password leak: What it means for phishing?  Answer:  Not Much! When people talk to us about phishing, they often want to know “What’s next in phishing? What else are you seeing?” This gets asked a lot, and is one of my least favorite questions because the truth is, email based spear phishing works as-is It has no reason to evolve right now.

Educause 2012 SPC: Quick Review

Last week I attended the Educause Security Professionals Conference 2012 in Indianapolis Indiana and was lucky enough to co-present with Emory University to discuss the phishing problems higher education face. This event had an entire track devoted to Awareness & Training and of course a major topic for discussion was phishing.

Anatomy of a vulnerability based spear phishing attack

Anatomy of a vulnerability based phishing attack This week SC Magazine named  the Chrome vulnerabilities the Threat of the month.  So, how would an attacker use this vulnerability in a spear phishing scam you ask? They know their audience Advanced threats know who they want to target, it doesn’t matter that your Skype handle is @kukubunga998 – they know you work for the organization they are targeting.  They also deduce (the same way a marketer does) that you are a Chrome user, or that you have it installed for some reason or another.  They know that your organization is big...

2011 – The year of spear phishing And spear phishing

An odd title for a blog post but something that has been on my mind for a while now. We get a fair amount media requests for comments or perspective on phishing stories.  This is a good thing. It’s nice to have recognition in your field. Of course 2011 was no shortage of phishing related news. (What’s up RSA, I’m looking at you. I’ve noticed you frequent our website a lot. How about a demo. Couldn’t hurt?)

Spear Phishing with Password Protected Zip Files

The Slashdot headline this morning reads: Spear Phishing Campaign Hits Dozens of Chemical, Defense Firms What is it about? Simple, the poison ivy trojan wrapped in a password protected ZIP file so it can get past filtering.  Symantec has an excellent analysis of these attacks in a paper titled: The Nitro Attacks: Stealing Secrets from the Chemical Industry by Eric Chien and Gavin O’Gorman.  You can read the entire paper here. “The most recent attacks focusing on the chemical industry are using password-protected 7zip files which, when extracted, contain a self-extracting executable. The password to extract the 7zip file is included in...

Current events: How news exposes your company to spear phishing attacks

Like many high-profile events, the passing of Apple’s co-founder and former CEO, Steve Jobs, has initiated a slew of new phishing attacks that are designed to play on recipients’ emotions about the event.  Steve Jobs and Apple themed phishing campaigns are in the wild but more concerning are the spear phishing attacks targeting iPhone users.  PhishMe understands how these events can adversely affect our customers therefore we have released a new phishing simulation theme designed to train susceptible users on how to identify and avoid current event based attacks. -Scott
