Hackers Take Advantage of People's Tax Returns

Episode 1379

Hacker

Hackers have been stealing people's information, filing their returns, and getting the refund. Last year, the IRS noticed that the FAFSA online system could get enough personal information that it could be used by hackers. In October, the IRS sent a memo to the Department of Education saying that the system could be abused. But because up to 15 million people used the system out of convenience, they kept it online. In February, the IRS noticed a pattern of fraudulent activity, and shut it down last month.

Ransomware has always been a terrible plague of the internet, where bad guys inject software into your computer through phishing emails. They usually trick you by saying it's from your bank, the IRS, or even your boss asking you to open something.

Denial of Service Attack Strikes Down Major Websites

Episode 1333

Ddos attack

A Distributed Denial of Service Attack (DDOS) hit the internet yesterday, tossing several networks offline. Leo says this happens all the time as robot computers are drafted to clog networks with phoney requests. What's disturbing about this particular attack is that it's using not only computers, but it's taking advantage of smart devices used in the home (called the internet of things), like routers, DVRs, smart refrigerators, and even internet enabled home security systems.

How can I prevent a DDoS attack?

Tyler from Lake Forest, CA

Episode 1311

Tyler does a lot of social media through YouTube and Twitch and he's been hit by a DDoS attack. Leo says that those attacks are easy and are usually done by a troll who has an axe to grind. But they can't go after Twitch, so he's attacking his personal IP address. Leo says to call the ISP and request a new address. Running through a VPN will prevent it since it's an encrypted tunnel and they can't see the IP.

Is my computer safe from hackers?

Kevin from California

Episode 1285

Kevin's mom went to a website and got a virus alert. She then called the phone number on it and they had her install something, which gave them control over her computer. Leo says that's a common scam. They probably installed a virus and maybe even turned her computer into a bot. The worst part is that they took her money and now have her credit card number. She realized her error and called him, though, and Kevin has since changed her passwords. She has trouble remembering passwords. Leo says many do and they end up using the same password over and over.

Episode 1263

A Hollywood hospital was hacked a few weeks ago and was essentially unable to operate. The hackers demanded 40 Bitcoins, which comes to about $17,000. This is considered "ransomware," where the hackers get you to run malicious software through a bogus updater like Flash that appears to be legitimate. This malicious software encrypts all data and threatens to delete everything unless you comply with the demands within a certain time frame.

GitHub Targeted in DDoS Attacks From China

Episode 1174

Hacker

Last week, Chinese hackers targeted GreatFire.org in a DDoS attack, and now are attacking GitHub. DDoS stands for "Distributed Denial of Service," and this attack brings down a website by hitting it with lots of bogus requests from thousands or even tens of thousands of computers distributed all over the world. GreatFire.org was spending $30,000 a day in bandwidth trying to keep up with the excess traffic.

The way they are getting this to be a distributed attack is by commandeering users of Baidu, a popular search engine in China.
