The cybersecurity landscape is constantly evolving, with cybercriminals devising new and sophisticated methods to target businesses of all sizes. While traditional malware attacks remain a concern, US businesses are increasingly facing a wave of novel threats that exploit trust and familiarity. Here, we explore three rising cyberthreats and how businesses can defend themselves:

1. Cat-Phishing: A Purrfectly Deceptive Scam

Cat-phishing, a play on "catfishing," leverages legitimate file transfer tools to trick users into clicking malicious links or downloading malware.  Here's how it works:

• Exploiting Trust:  Attackers exploit popular file transfer tools trusted by businesses, like Microsoft's BITS (Background Intelligent Transfer Service).
• Creating a False Sense of Urgency:  Phishing emails disguised as legitimate requests urge recipients to download urgent files or access links for critical information.
• Hidden Malware:  The downloaded files or accessed links contain malware that can steal data, disrupt operations, or launch further attacks.

Cat-phishing preys on a user's familiarity with trusted tools and the sense of urgency created by the emails. This makes it particularly dangerous because users might bypass usual security protocols when dealing with seemingly familiar applications.

2. Living Off the Land:  Weaponizing Legitimate Tools

Cybercriminals are increasingly turning to "living off the land" (LOL) attacks. This involves using legitimate system tools and scripts already present on a network for malicious purposes.

Here's how LOL attacks work:

• Exploiting Existing Resources:  Attackers leverage pre-installed system tools and scripts to avoid detection by traditional security software.
• Blending in with Normal Activity:  LOL attacks mimic legitimate system activity, making them difficult to identify.
• Escalating Privileges:  Attackers can use these tools to gain access to sensitive data or escalate privileges within the network.

The challenge with LOL attacks is that they don't rely on malicious software, making them harder to detect and prevent. Businesses need to be vigilant about monitoring network activity for suspicious behavior.

3. Fake Invoices: A Numbers Game with Deceptive Intent

Fraudulent invoices are a growing concern, targeting businesses that process large volumes of invoices electronically. Here's the breakdown:

• Targeting Busy Accounts Departments:  Attackers target accounts payable departments overwhelmed with invoice processing.
• Mimicking Legitimate Vendors:  Fake invoices appear to come from real vendors with slight variations in email addresses or bank details.
• Financial Loss:  Unaware employees might pay the fraudulent invoice, resulting in financial loss for the business.

The key to combating fake invoices lies in careful scrutiny of invoice details and implementing verification protocols for new vendors.

Staying Ahead of the Curve: How Businesses Can Fortify Defenses

To combat these evolving threats, US businesses need to adopt a multi-layered approach:

• Security Awareness Training:  Educating employees about cat-phishing, LOL attacks, and invoice scams is crucial for the first line of defense.
• Multi-Factor Authentication:  Implementing multi-factor authentication adds an extra layer of security for accessing sensitive data.
• Network Monitoring:  Continuously monitoring network activity can help identify suspicious behavior indicative of LOL attacks.
• Vendor Verification:  Establishing robust vendor verification processes can help prevent fraudulent invoices from slipping through the cracks.
• Staying Updated:  Keeping abreast of the latest cyberthreats and updating security software regularly is essential.

By recognizing these emerging threats and taking proactive measures, US businesses can build a stronger cybersecurity posture and protect their valuable data and resources.

In conclusion, the cybersecurity landscape is constantly shifting. Businesses must move beyond traditional malware defense and evolve their strategies to combat these novel threats. By combining user education, technological safeguards, and a proactive approach, US businesses can fortify their defenses and navigate the ever-changing world of cybercrime.
