Bonnie uses Eset's Smart Security, But she recently saw that an external intruder was blocked. She's worried that while her PC was safe, her other devices may have been compromised. Leo says that Bonnie's router probably blocked the bad traffic that comes lurking. There are bots that are looking for security holes, though. Getting attacked is normal, but the router will handle 90% of the attacks. The rest is covered by antivirus. Her cell phone IP address changes constantly, so it's mostly pretty safe.
We're familiar with DDoS attacks, which are "Distributed Denial of Service" attacks, but there's a new form of attack that's been happening online lately. It's called PDoS, or "Permanent Denial of Service," which actually bricks the device, destroying it permanently. The rationale is that if these devices weren't bricked, someone else would use it for a DDoS attack.
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.
