Recent Breach Incidents impacting Small Business

 

WEI MORTGAGE ( Virginia-based subsidiary of ARC Home) 
Financial Sector – Phishing

Small Business Risk: High (Forensic & Mitigation Costs, Financial Loss, Compliance Fines/ Penalties, Brand / Reputation Damage)

Exploit: Phishing: Employee Email Account Compromised

Risk to Individuals: High: Volume of PII elements disclosed in this breach PII.

What You Need to Know: Trusted with highly sensitive PII & Financial information, WEI clearly underinvested in cybersecurity basics:

  • Phishing Email Mitigation
  • Security Awareness Training
  •  2 Factor Authentication
  •  Encryption
Date Occurred or Discovered Unauthorized access to email accounts between Sept. 13 and Sept. 28, 2017.
Date Disclosed April 23, 2018 (7 Months)
Data Compromised According to the lender, with access to the email accounts in question, the hacker (or hackers) may have had access to numerous pieces of personal information including: Social Security number, date of birth, address, driver’s license or state identification number, passport number, bank account information, credit or debit card information, tax identification number, username and password, loan package information, and name.

Additionally, health insurance information, health insurance group number, and health insurance member number of certain individual may have been exposed.

The lender cautions that its investigation found no evidence of actual or attempted misuse of personal information thus far, but the investigation showed that some personal information was present in the impacted email accounts at the time of the incident.

How Compromised Employee’s email account accessed via phishing scheme which ultimately gained access to the employee’s account and perhaps other accounts.

Kansas-based MEDantex (medical transcription)
Healthcare Sector – Database Misconfiguration, Ransomware

Small Business Risk: High (Forensic & Mitigation Costs, Financial Loss, Compliance Fines/ Penalties, Brand / Reputation Damage)

Exploit: Database Security Misconfiguration, Single Factor Login, Ransomware Exploit

Risk to Individuals: High: Significant Patient Health Information Exposed. Downstream exploitability of patients, employee and medical professionals.

 What You Need to Know: This incident is particularly concerning for several reasons:

  •  MEDantex is still unable to determine how long its portal was exposed.
  •  Even when the portal was “secure”, it only required single-factor authentication. This is a major fail given that the portal housed PII PHI dating back to 2007.
  • Basic penetration testing should have picked up this vulnerability.  
Date Occurred or Discovered Length of time exposed is undetermined but was open as late as April 10, 2018.
Date Disclosed Unknown/April 2018
Data Compromised The number of exposed records was unclear, but one accessible directory alphabetized more than 2,300 doctors by their last name with access to downloadable records. While most records appeared recent, some dated back to at least 2007. This included administration tools that let anyone who visited the page add or delete users and search for medical records by patient or provider names.
How Compromised A security issue with an online portal that was apparently leaking medical records onto the internet that should have been password protected. Numerous online tools intended for use by MEDantex employees were exposed to anyone with a Web browser, including pages that allowed visitors to add or delete users, and to search for patient records by physician or patient name. No authentication was required to access any of these pages.
Customers Impacted Patient data from at least 2,300 providers
Attribution/Vulnerability Several MEDantex portal pages left exposed to the Web suggest that the company recently was the victim of “WhiteRose”, a strain of ransomware that encrypts a victim’s files unless and until a ransom demand is paid.However, misconfigured databases continue to plague the industry and are most often caused by user error. In fact, insider errors outnumber outside threat actors in the healthcare industry, according to Verizon’s latest breach report.
