Cybercriminals are targeting users of a popular classifieds site. Some 150,000 people have already fallen victim, and many more could soon follow.
Look out if you are a Craigslist user. Cybercriminals could be targeting you with a fake email. It looks like a harmless message from the classified ads website with a red headline reading,"Important, further action is required to complete your request."
"The bad guys go where the people are. A lot of people use Craigslist so you go where the money is," said Chris Duque a cybercrime specialist.
Once you click on the link it will take you to a website which will download malicious code that can take your important and personal information.
Your computer is then compromised and infected with malware giving criminals access to your private information, like bank account numbers and email passwords.
"They can spy on you and see what activity is going on and they can use your computer or computers to attack other computers," said Duque.
Cybersecurity specialists say Internet users always need to be alert. A good habit is to take time as you scroll through those emails.
"Look out for some red flags such as broken English or a sense of urgency asking you to do something," said Duque.
And remember, the effects of getting scammed is usually not instant. Investigators say it can take weeks before you know that you've been hacked. Watch for signs like a slow running computer or personal information suddenly disappearing. Specialists say it's important to make sure your security software is running and up to date when you are on the Internet.
