Thursday: Tricks and Traps

A message pops up on the mission control screen just after dinner.

It reads: "URGENT from Greenhouse Help Desk. Your Beacon sign-in stops working in ten minutes. Tap the link and type your password to keep it."

Comet reaches for the screen. "Better do it fast."

Wren catches his sleeve. "What do you notice? We never set up a help desk. And it wants your password."

Nova hovers in front of the link. "Pause," she says. "Ask who really sent this, and check another way."

Comet pulls her hand back. "So hurrying was part of the trick."

Phishing

Phishing is a technique that tries to trick a person into giving personal information.

A harmful link can be disguised inside a web page or an email message.

Unexpected emails, attachments, links and forms can be used to harm the security of a computing system.

They can come from unknown senders, or from known senders whose own security has been compromised.

Malware and other defenses

Virus and malware scanning software can help protect a system against infection.

Regular software updates help fix errors that could weaken a system's security.

Users should review the permission settings of programs to protect their privacy.
