The Excel Trick That Filters Data Instantly

Today, we’re learning how to use the FILTER function in Excel.

Instead of searching through rows or copying matching data manually, FILTER shows only the records that meet a specific condition. This makes your worksheet cleaner and saves time.

It’s useful for employee lists, sales regions, departments, products, or any dataset where you need to isolate specific information quickly.

By the end of this tutorial, you’ll know how to create a dynamic filtered list that updates automatically when the filter condition changes.

Can AI manage social media better than a human? Planable put it to the test

Planable's experiment tracked 7 Instagram accounts running the same fictional chocolate brand, measuring everything from posting consistency to content performance. The data challenges common assumptions about AI-generated social media.

Humans out-engaged AI 2.45x on engagement rate, and every human account beat every AI account on likes and follower growth. The gap came down largely to conversation.

Wondering how close AI is to replacing marketers? This experiment offers one of the clearest, numbers-backed answers yet.

The process is as follows

Step 1: Set Up the Data

Step 2: Type =FILTER and select the whole table

Step 3: Select the Filter Column

Step 4: Insert the cell with the filter condition

Formula:

=FILTER(B3:C30,C3:C30=E3)

We Are Done

And that’s how you can use the FILTER function in Excel to quickly display only the data that matches a specific condition. Whether you’re working with employees, divisions, sales regions, products, or customer records, this simple function helps you find information faster and create dynamic results that update automatically when the filter condition changes.

Cyber Threat Alert and Mitigation Guide: AI-Powered Threats, Deepfakes, and Synthetic Attacks

Issued by: [Your Organization Name]

Classification: Internal Use Only / Confidential

Effective Date: [Insert Date]

Urgency Level: High – Immediate Attention Required

1. AI-Driven Social Engineering and Deepfake Threats

The cyber threat landscape has escalated with the emergence of AI-powered social engineering attacks, including synthetic voice and video impersonations (deepfakes), automated spear-phishing campaigns, and chatbot-based deception.

Threat actors are leveraging advanced generative AI models to convincingly impersonate executives, HR staff, IT support, legal teams, and even trusted vendors. These deepfake attacks use manipulated audio and video to simulate real-time meetings, phone calls, or pre-recorded messages that appear indistinguishably real.

Impersonated requests may include urgent wire transfers, confidential document access, or password resets. The psychological pressure in these scenarios is amplified due to visual or auditory cues mimicking the intended sender.

Key Indicators of AI-Powered Deception:

Video calls where voice or facial expressions appear slightly unnatural or delayed.

Unexpected, urgent requests for credentials or financial actions delivered via voice or video.

Inconsistencies in grammar, tone, or phrasing not typical of the impersonated individual.

Requests that bypass typical approval workflows, especially from high-ranking “executives.”

Mandatory Preventive Measures:

Implement video verification protocols for financial or high-risk requests delivered via audio/video calls.

Enforce strict out-of-band authentication: Confirm all unusual or urgent requests through a separate communication channel.

Train all staff on identifying deepfake and synthetic media threats.

Disable automatic meeting acceptance in calendars to prevent unauthorized invitations.

Require internal keywords or authentication phrases during critical communications for identity validation.

Report all suspected impersonation attempts immediately to the cybersecurity team. Preserve all media and logs for forensic analysis.

2. Autonomous Malware, Smart Ransomware & AI-Enhanced Threats

A new class of malware is emerging: AI-enhanced autonomous malware, capable of adapting in real time, evading detection, and self-replicating across complex networks. Smart ransomware can now identify the most valuable data, escalate privileges, and negotiate payment with built-in chatbots.

Attackers are no longer operating manually – they are automating attacks at scale, using AI to identify vulnerabilities faster than defenders can patch them.

High-Risk Characteristics:

Malware that learns and adapts its behavior after scanning host environments.

Encrypted, modular code that changes signature upon each execution to bypass traditional antivirus tools.

Coordinated, multi-vector attacks combining phishing, credential stuffing, and system exploits.

Compromised backups, including ransomware that silently encrypts backup files before triggering an alert.

Required Mitigations:

Deploy AI-powered endpoint detection and response (EDR) capable of behavioral analysis and automated containment.

Maintain isolated, immutable, and encrypted backups, disconnected from primary networks.

Apply software patches within 24–48 hours of release, prioritizing critical vulnerabilities.

Implement Zero Trust Architecture (ZTA)—assume breach, verify all users and devices continuously.

Limit admin privileges and enforce least privilege access controls.

Conduct red-team simulations that include AI-simulated threats.

3. Secure AI Use, Shadow AI Risk, and Data Exposure

Employees increasingly use AI tools such as chatbots, assistants, and generative models for productivity. However, inputting sensitive company data into third-party AI platforms without security oversight introduces major risk—this is referred to as Shadow AI.

Once data is entered into public LLMs (Large Language Models), there is no way to fully retrieve or guarantee its deletion. Sensitive documents, internal policies, customer information, source code, and legal strategies have already been leaked by careless use of AI tools in global incidents.

Organizational Directives:

All staff must cease using unsanctioned AI platforms for any business-related task.

Only pre-approved AI systems vetted for privacy, compliance, and model training boundaries may be used.

Never input client, employee, or financial data into any AI tool unless explicitly authorized.

The IT Security Team will regularly audit network traffic for unapproved access to AI tools.

Legal and data governance teams must be consulted before engaging third-party AI vendors.

4. Secure Communications Amid Generative Attacks

AI has blurred the lines between human and machine communication. Chatbots and AI-generated emails are now capable of creating entire email threads that appear authentic. These may include spoofed addresses, reconstructed logos, and prior message history to gain trust.

Enhanced Protocols for Communication:

Digitally sign all internal emails involving sensitive or financial transactions.

Use encrypted channels (TLS, S/MIME, or PGP) for all confidential discussions.

Internal memos should include watermarking or unique reference codes.

Log and monitor message forwarding, especially to external addresses or personal inboxes.

If in doubt, verify the sender verbally or via direct call—assume deception if urgency is paired with secrecy.

5. Supply Chain and Third-Party AI Risks

Vendors and contractors using AI tools introduce risks that extend beyond your organizational boundaries. Many suppliers may lack cybersecurity maturity or visibility into how their AI tools manage your data.

Vendor Risk Controls:

Require all vendors to disclose any AI systems used in their services.

Include AI data usage clauses and liability terms in all supplier agreements.

Conduct penetration testing of third-party interfaces (APIs, portals, etc.).

Limit third-party access to only what is necessary and monitor API interactions in real time.

Suspend or terminate partnerships with vendors who refuse to adhere to data protection protocols.

6. Immediate Threat Reporting & Escalation Protocols

In the context of AI-enhanced threats, delayed reporting can result in exponential damage due to speed of malware propagation or social engineering success.

If You Suspect a Threat:

Do not interact further with the content or platform.

Immediately disconnect affected devices from the network.

Report the incident using the Cybersecurity Incident Hotline at [Insert Hotline Number].

Email the Security Operations Center (SOC) at [security@[yourorg].com] with full details, including any attachments or screenshots.

Retain all logs, messages, and communications for investigation.
