Since the start of 2015, healthcare has been hit with more ransomware than any other industry.

Headlines abound with tales of healthcare organizations declaring states of emergency, turning away patients, and often opting to pay ransoms just to end their nightmare.

The Top 9 Reasons Healthcare Organizations are a Hacker’s Best Friend

Posted by Lindsey Havens on Jan 10, '17

In recent years, healthcare organizations have been attacked with more frequency, velocity, and fervor than any other industry. IBM dubbed 2015 “the year of the healthcare breach” in their 2016 Cyber Security Intelligence Index, and if recent headlines are anything to go by 2016 wasn’t much better.

But why are healthcare organizations targeted so consistently? On the surface, gambling sites and financial institutions would seem like better targets, so what is it about healthcare organizations that threat actors find so tempting?

In the end, it all comes down to one factor: Money.

Why Ransomware Works, Why it Doesn't, and What it Will Work on Next

Cybersecurity is a field defined by its dynamism, as is crime. When analyzing trends to assess the future of these two
frequently overlapping spaces, the most efficient way to separate persistent threats from hype is by asking not just where the money is, but what the easiest way is to get it. While ransomware has had a lock on headlines all year, the most recent news stories all seem to emphasize increases in attacks targeting educational institutions, state and local governments, and healthcare organizations. Let's examine why this change from shotgun targeting to more focused targeting is happening.

How to Defend Against Ransomware.jpgAround 1.5 percent of spam emails contain malicious attachments or URLs, along with content designed to manipulate people into opening them.

#CyberAware: Spotlight on Ransomware

Posted by Lindsey Havens on Oct 18, '16

We field a lot of questions about ransomware, but there’s one in particular that comes up time and time again. “Are we at risk from ransomware?” It’s not a difficult question to answer. Yes, you’re at risk… Everybody is at risk. 

You see, there are plenty of ways for threat actors to spread ransomware. They create fake online advertisements and pop-ups, exploit known vulnerabilities to gain access to corporate networks, and they even drop USB sticks loaded with ransomware in public places. They’re pulling out all the stops to infect your systems with ransomware, so yes, you need to be concerned.

Posted by Lindsey Havens on Sep 9, '16

The Federal Trade Commission (FTC) responded to the rising ransomware threat on September 7, 2016 with a technology workshop in Washington, D.C. The workshop brought security experts, including PhishLabs' Vice President of Threat Research, Joseph Opacki, together to address common questions and concerns around the ransomware threat. Opacki  joined a panel during the workshop to educate the audience on the overall landscape of the ransomware threat and reasons it's proliferating at such a high pace.

Alma Ransomware: Analysis of a New Ransomware Threat (and a decrypter!)

With low overhead and risk of prosecution, ransomware attacks have outpaced banking Trojans in sheer number of incidents, if not profit.  Ransomware’s rapidly growing popularity has spawned dozens of variants, subtypes, and families as threat actors seek to outmaneuver researchers and competitors. In this dynamic threat landscape, alongside monitoring the established ransomware families for any change in tactics, techniques, or procedures, we monitor social media and underground markets for emerging threats. Through this process, our team was alerted to and began an investigation of what is likely a new threat actor’s first attempt at ransomware design and distribution.

Recently we observed a new type of ransomware, called Alma Ransomware, being delivered via exploit kit. Often hidden on web servers, exploit kits (EK) are toolkits used by threat actors that exploit vulnerabilities in visiting users’ web browsers to deliver malicious payloads.  Alma Ransomware (MD5 Hash: 92f8a916975363a371354b10070ab3e9) was observed being delivered via the RIG Exploit Kit. The malicious payload tripped only one indicator on VirusTotal at 2016-08-22 14:51:15 UTC:

Phishing Attacks Come in a Wide Variety of Flavors...Make Sure Your Employees Get a Taste of Each

While more organizations than ever before recognize the need to educate and train their employees on the dangers
of phishing attacks, it’s important that those in charge of training make sure employees understand that not all phishing probes are alike.

In 2015, PhishLabs analyzed more than 1 million confirmed malicious phishing sites residing on more than 130,000 unique domains. While the typical consumer phishing attack has garnered much attention, the specialized business spear phishing attack poses increasing risk for a company and its employees. 

Here’s a brief menu of the types of phishing attacks your employees need to recognize and avoid.
