What is remote access?
SecurityMetrics PCI forensic investigators discovered that remote access is a top avenue hackers use to gain access into merchant systems in order to install custom-tailored POS malware. Other attack vectors include email phishing attacks, third-party vendor compromise, insider threats, social engineering, and using vulnerable applications to compromise systems.
How does POS malware work?
POS malware succeeds when system vulnerabilities– cracks in the wall – are present. These cracks allow hackers into merchant systems. The best way to prevent such attacks is to discontinue remote access, but in today’s world, that’s not always a realistic option. Alternatively, by taking simple steps and encouraging a multi-layered approach to security, merchants can secure their organization against a potentially devastating compromise.
How many people were affected by POS malware in 2014?
In the last two years, POS malware has compromised 100 million payment cards and potentially affected up to one in three people in the U.S.
What is a guest account?
Guest and default accounts allow anonymous computer and system access. Disabling any guest accounts on each computer protects against unauthorized users. Disabling or changing default accounts makes it difficult for attackers to research installation guides online to get the default username and password of applications and systems. Many POS systems and applications come installed with default or guest accounts and passwords that should be changed to make it more difficult for attackers to enter systems.
