GitHub Hit by Largest Ever DDoS Attack (3/1/2018)

GitHub was hit yesterday by the largest DDoS attack ever recorded. The DDoS attack generated a flood of traffic that peaked at 1.35 Terabits per second.

Post Office Mail Scam (2/26/2018)

The USPS has a service that allows you to see a preview of your snail mail on-line. Unfortunately when the USPS rolled this out their identity verification was lax and they did not notify by their own mail system that someone signed up. Therefore it was very easy for scammers to sign up to get a preview of your mail and know when credit cards, bank statements or checks were delivered. The USPS now has implemented a notification system so you know when someone potentially signs up. It is suggested that you sign up for this notification process.

Chrome Browser Scam/Ransomware (2/8/2018)

Security researchers are reporting that hackers are exploiting a bug in Chrome to try to extort money from unsuspecting users. The way it works is that upon navigating to a hacked or invalid web site, your browser may display a message telling you to call a number and then lock up the browser and eventually your Windows machine. If you do encounter this issue on Windows you may use Task Manager to kill the Chrome browser or you can reboot your machine. On MacOS your Mac will eventually tell you that your browser is unresponsive. Under no circumstances should you call the number popping up on your machine. Chrome has not yet issued a patch.

Another Flash Exploit (2/1/2018)

Adobe issued a security warning that attackers are exploiting a new security hole in its Flash Player software to hack into Microsoft Windows computers. Adobe said it will issue a fix in the next few days. Adobe is recommending that users turn on protected view in Windows to mitigate this issue. We recommend that all users turn on protected view on their computers.

File Taxes Early to Prevent Fraud (1/29/18)

Today January 29th is the first day you can file your 2017 tax return. A favorite tactic of scammers and hackers is to file a false tax return using your stolen identity and receive a large tax return. Tax return fraud impacts hundreds of thousands of US taxpayers annually and is expected to climb this year due to the Equifax breach. One way to prevent this fraud is to not wait until April 15th but file as early as possible.

If you were a victim of the Equifax breach you should should consider submitting an Identity Theft Affidavit (Form 14039) to the IRS. Also be aware that if you froze your credit due to the Equifax breach and you are required by the IRS to use a PIN to file electronically you have some extra steps to perform.
