Now more than every before, security is essential. Yet, many small and medium-sized enterprises (SMEs) often overlook one of the simplest yet most critical aspects of digital security: the 4-digit PIN. While these seemingly harmless numbers may appear secure, they can pose significant risks if not managed correctly. This blog post will dive into the hidden dangers of 4-digit PINs, exploring common combinations, the risks they present, and how to enhance your security measures. As an business owner, safeguarding your business’s data should be a top priority, and understanding the vulnerabilities associated with 4-digit PINs is a crucial step.

The chart above illustrates the most to least common 4-digit PINs based on data from multiple breaches. A surprising number of people use easily guessable combinations, making their accounts particularly vulnerable to attack. Some of the most common PINs include:

• 1234: Unsurprisingly the most common PIN, used by a significant number of individuals.
• 4321: Another frequently used combination, simply the reverse of 1234.
• Birth Years (19xx): Many people use their birth year as a PIN, which is easily guessable with a bit of social engineering.
• Dates in MM/DD or DD/MM Format: People often use significant dates, such as birthdays or anniversaries, which can be deduced from personal information.

Using easily guessable PINs like the ones mentioned above exposes your business to several risks:

1. Brute Force Attacks: Hackers use software to quickly guess PINs. Common combinations are often the first ones tried.
2. Social Engineering: Attackers can gather personal information through social media or other means and use it to guess your PIN.
3. Data Breaches: If your PIN is among the commonly used ones, it might already be compromised in a data breach.

The consequences of compromised PINs can be severe:

• Financial Loss: Access to bank accounts, payment systems, and financial data can lead to significant monetary loss.
• Data Theft: Sensitive business information, including client data, proprietary information, and strategic plans, can be stolen.
• Reputation Damage: A security breach can tarnish your business’s reputation, leading to loss of client trust and potential business.

To protect your business, consider the following strategies:

1. Avoid Common Combinations: Steer clear of easily guessable PINs like 1234, 4321, or birth years.
2. Use Random Numbers: Generate random PINs that are harder to guess. Avoid patterns or sequences.
3. Change PINs Regularly: Update your PINs periodically to mitigate the risk of them being compromised.
4. Multi-Factor Authentication (MFA): Implement MFA wherever possible. This adds an extra layer of security by requiring another form of verification besides the PIN.
5. Educate Employees: Ensure your team understands the importance of strong PINs and practices good security hygiene.

Engaging with outsourced IT support can significantly enhance your security posture. Here’s how:
