The Cost and Risks of Cybersecurity

Posted by Willie Mata on February 5, 2019

Like mutating bacteria, cyberattacks have been evolving into ever more pernicious threats. As quickly as companies arm themselves against the most recent attacks, a new and even more complex infection arises.

Case in point: cybersecurity researchers now believe that two banking trojan horse malware strains – named Trickbot and Emotet – are now being used by attackers to gain a foothold in enterprise networks, and then, after a period of targeted reconnaissance, download and launch destructive Ransomware code.

Both Trickbot and Emotet commonly use phishing or spam emails with executable attachments to initiate and quickly spread the malware by distributing infected messages to others in your email address lists – instantly making the messages more trustworthy, as they are coming from a known source. Attackers are now frequently using Emotet as the primary loader to any of a number of other trojans, like Trickbot.

Upon the infection of your networked computer, the trojan makes an initial connection to a command and control (C2) server to let the C2 server know it is active and available for additional commands. The C2 server will randomly deliver new variants of code, altering their behavior over time and making it both harder to detect with standard tools, or impossible with no tools. There is no preset schedule to these communications.

Some variants give the malware the ability to traverse across the victim organization’s network looking for targets of value – often involving the financial functions of an organization – in order to inflict the maximum amount of damage.

Somewhere, right now, out there on the Internet, someone is poring over a collection of hundreds of affordable exploit kits available on TOR and trying to decide which one to purchase to attack your network.

Researchers believe that the TrickBot operators are renting their service to cyber criminals, who then use this to gain access to networks where TrickBot is installed. Ransomware such as Ryuk enters enterprise systems long after they have been infected by Trickbot. It’s estimated that Ryuk and Trickbot have enabled operators to generate $3.7 million worth of Bitcoin since last August.

Because most organizations don’t have the time, manpower or tools needed to locate these network intruders, attackers can take their time selecting when and where to best unleash their malicious payloads. And they can be very patient. There have been several documented cases where the hackers were in the network for more than 12 months before they encrypted the victim's data and demanded a ransom.

For example, Marriott revealed that hackers had access to the networks of many of its hotel chains for four years before they breached the hotel’s reservation system.

They know your email addresses, they know where you work from LinkedIn, Twitter, Facebook or other social media, they know who your peers are at work, and in some cases they also know your password because you use a common one for all of your accounts because it's convenient...and with a little effort they can figure out which of your friends deal with the financial transactions in your company. All they need is for you to click on an innocent or very convincing link in an email sent to you from someone you believe is a peer...and they got you.

Don’t make the mistake of not having the proper tools or services to detect and stop an infection before it evolves into a Ransomware Recovery Incident. The longer you wait, the greater the potential impact..

 

Insurance options

Certainly, there are ways to offset the potential loss. Companies operating in highly regulated markets – or with contractual or legal requirements – should consider purchasing cyber insurance. In fact, any organization that deals with Personally Identifiable Information (PII) or Protected Health Information (PHI) should limit their cyber exposure. Most cyber insurance policies cover costs related to first-party breach expenses, such as:

  • Legal
  • Forensic Audit
  • Breach Notification
  • Credit Monitoring
  • Business Interruption
  • Data Restoration
  • Extortion
  • Telecom Fraud, and
  • Social Engineering Fraud.

 

Let the buyers beware!

Unfortunately, your cyber policy may not pay your claim if the attack strain was created by a nation state or is classified as a cyber weapon. In 2017, a major insurer refused to pay a $10 million claim by a U.S. company infected with NotPetya malware.

Launched as part of the Kremlin’s effort to destabilize Ukraine, NotPetya was called “the most destructive and costly cyberattack in history,” by the White House. The insurer refused payment by claiming the NotPetya malware was a “hostile or warlike action in time of peace or war” by a “government or sovereign power.”

In cases like these, your best defense is a reputable insurance broker. A broker will get you the best deal on the most comprehensive policy. But, before you go out and interview potential insurance carriers, invest some time to learn more about cyber insurance by viewing the excellent collection of free videos found at the Travelers Cyber Academy.
