Oppenheimer & Co. Inc. October 06, 2025

October is Cybersecurity Awareness Month, a timely reminder that protecting your personal and professional information online is more important than ever. As cyber threats continue to grow more complex and frequent, individuals and organizations alike must stay proactive about digital safety. 

From phishing attacks to AI-driven voice cloning and data breaches, the risks are real – but so are the tools to defend against them. Below are essential tips and best practices to help you strengthen your digital defenses and stay secure in an increasingly connected world.

Strengthening Passwords and System Security:

  • Utilize robust passwords, updating them regularly.
  • Keep software current and employ anti-malware protection.
  • Exercise caution and avoid clicking on suspicious links or pop-ups.

Spot the Scam – Stay Ahead of Fraud and Cyber Threats:

  • Stay informed about cybersecurity developments, especially if organizations you engage with are targeted.
  • Verify URLs to ensure legitimacy, as scammers often mimic authentic organization websites.
  • Refrain from sending money through cryptocurrency, gift cards, or money transfers, as legitimate organizations won't demand payment through these channels.
  • Never share personal financial information in response to unsolicited calls, emails, or texts.

Scan QR Codes with Caution:

  • Be vigilant against malicious QR codes used by scammers for phishing campaigns.
  • Avoid scanning unfamiliar QR codes to prevent redirection to phishing sites.

Fake Calls, Real Risks – How to Handle Suspicious Phone Activity:

  • Exercise caution with unknown caller IDs, websites, and text messages, as they might be phishing attempts.
  • Refrain from disclosing personal information, as voice recordings can compromise your accounts.
  • Hang up and call the company contacting you directly by using the official number listed on their website.

Cybersecurity Awareness Month is the perfect time to evaluate your digital habits and reinforce your defenses. Staying safe online requires awareness, vigilance, and ongoing action. By following these best practices, you take meaningful steps toward protecting your information from malicious threats.
