IoT, rotten home AP firmware, freaking Wi-Fi cameras: They’re all eating your lunch. Here’s an Advanced Persistent Threat notice: EVERYTHING AROUND YOU can give you a miserable day. It’s now entirely myopic, and hence irresponsible, to think there is such a topic as enterprise security because sadly video cams in Macedonia can give your hosting environment a DDoS headache. Poor TLS handshakes crack browsers open like an egg. Your router vendor had all of the hardening of a “fairy tap.” Remember those when you were a kid? A fairy tap was a gentle touch, designed to invade your space but do no damage. Now the damage is pOwn1ng your infrastructure. Or you business partner’s infrastructure. To read this article in full or to leave a comment, please click here

Worth Reading: Car Makers Align with 5G

5G wireless technology has become a little like fully automated cars. Nearly every day some new study is forecasting an earlier than previously anticipated arrival of fully autonomous cars, while some respected expert is claiming full automation is decades away.

As a parent to two kids in elementary school, I’m continually amazed at how quickly teachers and students are using technology to effectively teach and gain new 21st Century skills. Instead of being bombarded with handouts every week, I receive only the ones that require my attention and acknowledgment; all other communication is through email or educational apps. For example, my kindergartener’s teacher uses Seesaw to share my son’s work in the classroom with me. Changing from asking “What did you do at school today?” to saying “I love what you did at school this week!” always brings a smile to his face.

Attackers use hacked home routers to hit Russia’s 5 largest banks

Botnets made up of hacked home routers were used to launch distributed denial-of-service attacks against the five largest financial organizations in Russia.The attacks occurred on Monday, Dec. 5, and were detected and mitigated by Rostelecom, Russia's state-owned telecommunications company. The attacks peaked at 3.2 million packets per second (Mpps) and the longest attack lasted for over two hours, Rostelecom reported Friday.The company did not provide a bandwidth measurement for the attacks, but 3.2Mpps is not that much. DDoS mitigation providers regularly see attacks that exceed 100 Mpps and a very large September attack against the website of cybersecurity blogger Brian Krebs peaked at 665Gbps and 143Mpps.To read this article in full or to leave a comment, please click here

How this analyst targeted a phisher

Not unlike any other threat analyst, Marc Laliberte's email inbox fills up minute by minute. Some of which has made its way past the spam filter. The WatchGuard employee decided to finally act upon a certain phishing attempt in hopes of teaching the bad guys a lesson.   Spear phishing is a type of phishing attack in which the perpetrator customizes their attack to a particular individual or group of individuals.
