AI-powered voice cloning is a real and rapidly growing fraud vector. Scammers use readily available tools to clone voices from short audio clips and impersonate family members or executives, causing significant financial losses documented by the FBI, FTC, and academic research.

Modern security guidance from NIST has shifted away from requiring complex mixes of symbols, numbers, and mixed case toward emphasizing overall password length and uniqueness, since long random passphrases are often both more secure against modern cracking methods and easier for people to actually use.

Covering a laptop webcam is a low-cost precaution against a documented and real category of malware called remote access trojans that can activate a camera without the indicator light turning on in some cases, a practice endorsed publicly by figures including former FBI Director James Comey rather than being an irrational fear.

Fake antivirus software, sometimes called scareware, tricks users into installing malicious or useless programs by displaying alarming but fabricated warnings about nonexistent infections, then charges for a fake fix or installs actual malware, a scam that peaked in the late 2000s and continues in updated forms today.

Fraudulent text messages and emails impersonating postal services and courier companies, claiming a package delivery failed or requires a small fee, are a well-documented and widespread phishing technique used to steal payment details and personal information.

Fake invoice scams send businesses or individuals fraudulent bills for goods or services never ordered, relying on routine payment processing to slip through without scrutiny, and business email compromise variants targeting companies have caused billions of dollars in reported losses.

QR code scams, sometimes called quishing, use fraudulent codes placed on parking meters, restaurant tables, or sent via email to redirect victims to malicious websites designed to steal payment details or login credentials, and reports of this scam type have risen substantially since 2021.

Wangiri, or one-ring, scams place a brief automated call that immediately hangs up, hoping the recipient calls back a premium-rate number and unknowingly incurs large per-minute charges, a fraud pattern originating in Japan that has since spread internationally through spoofed international numbers.

Phishing remains one of the most common and effective cybercrime techniques, using fraudulent emails that impersonate trusted organizations to trick recipients into revealing credentials or installing malware, and it continues to be a leading cause of data breaches and financial fraud worldwide.

Public Wi-Fi is not always safe. Open networks still carry real risks, including rogue hotspots, interception of unencrypted traffic and exposure of DNS lookups and metadata, although the widespread adoption of HTTPS has substantially reduced the practical danger for typical browsing compared with a decade ago.

Sextortion scams threaten to release real or fabricated compromising images or claim to have recorded a victim through hacked devices unless payment is made, and law enforcement agencies report a sharp rise in cases targeting both adults and minors in recent years, including a growing number linked to teen suicides.

SIM swap fraud involves criminals transferring a victim's phone number to a device they control, often by social engineering a mobile carrier, allowing them to intercept one-time verification codes and take over bank, email, and cryptocurrency accounts protected by SMS-based authentication.

Tech support scams trick victims into believing their computer has a serious security problem, then charge for unnecessary services or gain remote access to steal money and personal information, and they remain one of the most commonly reported fraud types affecting older adults.

Handling plugged-in electrical devices with wet hands or while standing in water is genuinely dangerous. Impurities in ordinary water and wet skin lower the body's electrical resistance enough for household voltage to become lethal, which is why electrical codes require GFCI protection in bathrooms and kitchens. If someone is being shocked, cut the power first and never grab them directly.
