Mac Ransomware – Daily Security Byte EP. 226

Antivirus companies have found incomplete versions of Mac ransomware, researchers have created proof-of-concept (PoC) variants to demonstrate the possibility, and criminals have experimented with ineffective web-based “policeware” for Macs, but we’ve not seen Cryptolocker-level ransomware targeting Macs in the wild… that is until now. Watch today’s Security Byte video to learn more about the new KeRanger ransomware, and how to defend yourself against it.

Linux Distro Backdoored – Daily Security Byte EP. 220

It would suck to have your website hacked, and your user database stolen by malicious attackers.

Apple vs.The FBI – Daily Security Byte EP. 218

This week, Apple’s CEO, Tim Cook, posted a public letter to his customers explaining why Apple intends to fight a court order demanding that they help crack the security of a dead terrorist’s iPhone. Hearing this, you might think, “I don’t use Apple stuff, so I don’t care,” or “this doesn’t affect me and I want them to catch terrorists.” The problem is, this issue could set a precedent that will affect all of us. Watch today’s Byte to learn more about this issue and why it could affect you, and check out the references belowespecially Cook’s Letterfor more details.

Show Note: Unfortunately, this episode is posting a few days late, and I missed a day of the Daily Byte. Technical issues forced me to re-shoot the content.

Backdoors and Watering Holes – WSWiR Episode 162

Cyber security has become mainstream. Nowadays, there’s more information security (infosec) stories each week than the average IT professional can keep up with. If you find yourself falling behind, let our daily and weekly videos keep you informed. If you watch my Daily Security Bytes, you can probably skip this weekly summary. However, if you prefer to recap the week in one go, this video is for you.

This week’s episode includes surprising new updates to the Ashley Madison hack, a backdoor in a bunch of consumer routers, and a watering hole attack targeting the EFF. Watch the video below for the scoop, and check out the references section for more.

Show Note: A couple notes this episode. First, while I posted last week’s summary video to YouTube, I was not able to blog about it due to my early week travel. If you missed it, you can view it here, or just subscribe to my YouTube channel to see my videos right when they come out. 

Also, I will be traveling in Europe all week to attend WatchGuard partner conferences. I will try to post some videos, but I probably won’t get to one every day, and will post them at unusual times.

Today’s show shares details about the Android Fake ID vulnerability, talks about a new PoS system attack campaign, and warns of an industry-wide USB problem researchers will disclose at Blackhat. Check out the video for the details and some advice, then scroll down to the Reference section if you are interested in other infosec news from the week.

As an aside, I will be attending Blackhat next week, which means I may not post the video at its regular time. However, it also means I’ll cover my favorite briefings from the show, so if you can’t attend be sure to tune in to get a taste of the popular security conference. Have a great weekend.
