Is email phishing just an I.T. Issue?

Look at any news source today and you are bound to see yet another article on how Phishing is affecting businesses of all sizes in the U.S. and overseas.  With the amount of money that is being spent on protecting networks and end points, why is phishing such an easy way to disrupt operations or even worse, steal and corrupt your data.  The answer is easy, people are the weak point.  

Did you know that…

  • 1 in 131 emails contained malware, the highest rate in 5 years *
  • Ransomware damages are up 15X in the last 2 years, expected to worsen **
  • Business Email Compromise scams, relying on spear-phishing emails, targeted over 400 businesses every day *

How do you stay protected?

The solution to phishing is also easy, Test and Train your employees consistently.  Have a Phishing Campaign performed on all the e-mail users of the company.  See who would be willing to click that link or even supply credentials.  The next part is training those same employees on how to spot a phishing e-mail because as we all know, e-mail filters will not stop all of them from reaching us.  It’s all about raising Information Security Awareness consistently and often.

Innovative Solutions can help your business test employees with a Phishing Campaign and with training materials to help raise consistent awareness.

Everything You Need To Know About The WannaCry Ransomware Attacks

On Friday, May 12, a ransomware variant titled “WannaCry” infiltrated several UK-based National Health Service locations. Since then, it has spread across 200 countries and infected more than 200,000 endpoints.

Three WannaCry Facts You Should Know

Fact 1

WannaCry is a ransomware variant that leverages a known Microsoft SMB vulnerability (EternalBlue).

Targeting unpatched Windows operating systems (Windows XP, 8, Vista, 7, 2012, 10, and Server 2003). Infected users experience file encryption in exchange for a $300 bitcoin ransom. The malware has been documented propagating laterally, rapidly infecting affiliated endpoints.

Fact 2

Microsoft has since released a patch to fix legacy operating systems (Windows XP and onward).

While a patch to remove the underlying vulnerability (Windows Vista and onward) had been issued on March 14, delays in applying security updates, and lack of support by Microsoft for legacy Windows versions have left users vulnerable.

Fact 3

A short-term “kill-switch” was identified that prevented the infection of additional systems.

Since then, new variants of the malware, which lack the kill-switch, have been reported. As of May 15, 2017, the threat is still prevalent and at large.


WannaCry Details and Misconceptions

Important information is getting lost amongst the online clutter – take the time to eliminate all WannaCry misconceptions.

  • The most common WannaCry variant uses IPC$ shares and SMB resources to propagate.
  • WannaCry leverages the exploit EternalBlue – the vulnerability drops an executable onto the targeted system and conducts a beacon check for the kill-switch domain. If it doesn’t receive a response, then the malware executes the ransomware routines.
  • WannaCry installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (Source: Malwarebytes)
  • On the LAN, it scans for all enumerated addresses within its LAN with an open port 445 & 139 (i.e. the SMB port).
  • On the internet, it scans for random IP addresses to see if it has an open port 445. If it finds one with an open port, it scans all devices in the same /24 IP range (i.e. IP addresses that share the first three octets) as the found address.
  • WannaCry kills SQL Server, Exchange, MySQL and installs TOR on the endpoint.
  • When the ransom demand-time elapses, the malware writes up to 1GB of free space on host-disk and then deletes the file.
  • A variant of WannaCry has been previously documented before this instance.


A Cost-benefit Analysis Can Help When It Comes To Ransomware

We live in the real world and often we work for companies looking to maximize their profits. It is practical for them to perform a risk-based cost benefit analysis to determine whether to pay or not. To pay or not should be a business decision based on which option is most cost effective. Consider these variables: 

Question 1

What will happen if you lose your data?

Is the data or system critical in nature? What is the potential impact to the information system, the business process, or the organization? Are there adequate backups and a recovery process to minimize operational interruptions?

Question 2

What is the relative cost associated with paying?

Most ransom demands are meant to be reasonable to incite you to pay.

Question 3

What is the probability that your data will be decrypted?

An “unethical” extortionist could receive payment and choose not to decrypt your data.

Question 4

What are the chances this will happen again?

An attacker could leave malware on your systems in the form of a backdoor, which they could use to compromise you for additional ransom. An attacker could also spread the knowledge that you are willing to pay, inciting other cybercriminals to attack you.


A Good Strategy Is the Key

WannaCry is a good reminder that security threats are often unknown and unpredictable. The only way to maintain effective defense is through a comprehensive and flexible security program.


Defense in depth is the best approach to protect against unknown and unpredictable attacks. Effective anti-malware, diligent patching and vulnerability management, and strong human-centric security are essential.


There are two types of companies – those who have been breached and know it, and those who have been breached and don’t know it. Ensure that monitoring, logging, and event detection tools are in place and appropriate to your organizational needs.


Raw data without interpretation cannot improve security, and is a waste of time, money, and effort. Establish a tiered operational process that not only enriches data but provides visibility into your threat landscape.


Organizations can’t rely on an ad-hoc response anymore – don’t wait until a state of panic. Formalize your response processes in a detailed incident runbook in order to reduce incident remediation time and effort.
