Heartbleed Bug- WSWiR Episode 102

April Patch Day, Raided Pen-Tester, and OpenSSL Heartbleed

Information security news never stops, even if I have to post it from a Changi Airport lounge. If you need to learn the latest cyber security news, including what to do about the biggest vulnerability of the year (so far), you’ve found the right weekly video blog.

This week’s “on-the-road” episode covers Adobe and Microsoft’s Patch Day, an allegory on why you should avoid greyhat pen-testing, but most important of all, information and advice about the major OpenSSL Heartbleed vulnerability. If you use the Internet, you need to know about the Heartbleed flaw, so click play below to watch this week’s video. Finally, make sure to check the Reference section for links to the stories and some extras; especially if you are interested in all the WatchGuard Heartbleed information.

Microsoft Black Tuesday: Word 0day Fix & More

Microsoft’s monthly Patch Day went live earlier today. As expected they released four security bulletins, fixing flaws in Windows, Internet Explorer (IE), and Office. Microsoft rates two of the bulletins as critical, one that fixes Word vulnerabilities (including a zero day one I warned about earlier) and another that fixes IE flaws.

If you use the affected Microsoft products, you should apply these patches as soon as you can. I’d apply the updates in the order Microsoft recommends; the Word update first, the IE one second, and the Windows and Publisher updates last.

In any case, I’ll share more details about today’s Patch Day bulletins on the blog throughout the day.  However, I am currently traveling in Asia, so my blog posts may be late due to timezone issues and travel. So I recommend you check out the April bulletin summary in the meantime, if you’d like an early peek. Also, keep in mind that Adobe released a Flash update today as well. — Corey Nachreiner, CISSP (@SecAdept).

Microsoft Black Tuesday: Patch IE Zero Day & Windows Vulnerabilities

Microsoft’s March Patch Day is live, and looks to be by the numbers. As expected, they released five bulletins, including one that contains a fix for a zero day vulnerability in Internet Explorer. Their Patch Day summary highlights five security bulletins that fix 23 vulnerabilities in various Microsoft products, including Internet Explorer (IE), Windows and its various components, such as Silverlight. They rate two of these bulletins as Critical, and the rest as Important.

MS Patch Day: March 2014As I mentioned in my notification post, the most important update this month is the IE cumulative patch. Besides fixing 23 memory corruption flaws, many of which attackers could exploit to execute code, one specifically fixes a critical zero day flaw which attackers have been leveraging in watering hole attacks. Though Microsoft released a Fix-it for this vulnerability a few weeks ago, this update completely corrects the underlying issue. Make sure to install the IE update on all your clients as soon as possible. Hopefully, you already have Automatic Updates set to do it for you. Of course, you should also install the Windows updates too, especially the DirectShow one. If an attacker can trick one of your users into viewing a malicious JPEG image, he could exploit it to gain control of that user’s computer, with their privileges. You don’t want that.

While we are talking about Windows updates, let me take this time to continue to remind you that these updates are among the last that Windows XP will receive. XP users will likely see a few more updates next month, but after than it goes End-of-Life. Hopefully, most of you are saying, “Why do I care? I’ve been using Windows 7 or above for years.” But for the stragglers out there, you might want to consider upgrading to a more recent version of Windows. While I don’t want to come off as promoting Microsofts “upgrade” sales message, I do believe XP will likely pose more risk once the official updates stop. It seems very likely that some cyber attacker (or nation-state groups) out there are sitting on a zero day XP exploit or two; saving them until after Microsoft’s fixes run out. You might want to get away from XP before that happens.

In any case, I’ll share more details about today’s Patch Day bulletins on the blog throughout the day. Meanwhile, check out the March  bulletin summary now, if you’d like an early peek. — Corey Nachreiner, CISSP (@SecAdept).

Uroburos APT- WSWiR Episode 97

SOHO Pharming, Trio of Data Breaches, and Russian APT

I still remember ten years ago, when I used to wish more people would realize the dangers of the Internet and the sad state of cyber security. Back then, it seemed like I had to work to convince someone that there was any computer security problem at all. Boy has that changed… Now I feel overwhelmed by the amount of information security news that breaks each week. If you’re interested in computer security news, but feel overwhelmed yourself, let my short video summarize the important news for you.

Today’s episode covers a SOHO pharming campaign that’s hijacking routers in Europe and Asia, another trio of big network and data breaches, and a new advanced, nataion-state level attack that allegedly comes from Russia. Watch the video for my quick summary, and/or check out the links below for more details, and some extra security stories to boot.

Enjoy your weekend, and keep safe out there.

0day Watering Holes – WSWiR Episode 96

Flash and IE 0day, Watering Holes, and Router Worms

It’s Friday, Friday, gotta get your InfoSec on Friday….

Seriously though. If you are looking for a quick round-up of this week’s biggest security news, this is your show. In it, I cover what I think are the top three information and network security stories of the week, vlog style. If that sounds good, keep reading.

This week’s episode covers an advanced watering hole attack that leverages two zero day vulnerabilities, a worm that’s infecting a popular brand consumer router, and new vulnerabilities that affect devices which fall under “the Internet of things” category. If you’d like all the details, including how to protect yourself, watch the video below. Or if you prefer to read, check out the Reference section for links to those stories and more.

Quick show note. Next week I’ll be attending the annual RSA Security Conference. Though I still hope to produce a video on the road, I may have to settle for a text version of our weekly Infosec news if I get too busy. Keep an eye on the blog for the latest, and have a great weekend.

The Mask APT Campaign – WSWiR Episode 95

400Gb DDoS, More Bitcoin Attacks, and The Mask APT

If you’re looking for a quick synopsis of the latest information security news and advisories, our quick weekly video can provide it for you. This week’s episode was shot literally right before I had to run out to catch a plane, so please excuse the low quality webcam footage. 

Today’s episode includes a quick rundown of the week’s Microsoft and Adobe patches, news about the latest world record-breaking DDoS attack, some Bitcoin hijinks, and the details around a new cross-platform advanced attack campaign discovered by Kaspersky. Check out the video for all the details, and give the Reference section a peek for links to other infosec stories, including last minute news of a new Internet Explorer (IE) zero day attack.

Have a great weekend (and President’s Day for US readers), and be careful online.

Microsoft Black Tuesday: IE Fix Leads the List of Critical Updates

Today’s Microsoft Patch Day will probably be a bit busier than expected. It looks like Microsoft called a last minute audible, releasing seven security bulletins rather than the five I mention in last week’s security video. The good news is this last minute play change might help your security team win the game by providing your users with a more protected web browser.

Microsoft Patch Day: Feb, 2014

Microsoft Patch Day: Feb, 2014

February’s Patch Day summary highlights seven security bulletins that fix 32 vulnerabilities in various Microsoft products, including Internet Explorer (IE), Windows and its various components, and Forefront Protection for Exchange. They rate four of these bulletins as Critical, and the rest as Important.

This month, the most important updates are probably the most unexpected ones. Microsoft’s original advisory suggested they planned on releasing updates for Windows and one of their security products (which we now know is Forefront Protection), but they had not mentioned the IE or VBScript updates they released today. However, both these unexpected updates make great additions to this month’s Patch Day. The IE cumulative patch fixes 24 serious vulnerabilities, including one disclosed publicly; many of which attackers can leverage to execute code in drive-by download attacks. Though Microsoft hasn’t seen anyone exploiting these flaws in the wild yet, I expect attackers will surely reverse this update and start exploiting these flaws soon. The VBscript update is no slouch either, as it too fixes a code execution flaw. If bad guys can entice you to a web page with malicious code, they can use these flaws to”pwn” your computer.

Of course, you shouldn’t ignore the expected updates either. Two of them—the critical flaws in Direct2D and Forefront Protection for Exchange—also allow remote attackers to execute code on your systems. In short if you are a Microsoft administrator, you should apply today’s critical updates as soon as you can, and take care of the Important while you’re at it. In general, I recommend you test Microsoft updates before deploying them throughout your production network, especially server related updates that affect critical production servers. This is probably especially this month, for the two surprise updates. Since the IE and VBScript updates came out a bit earlier than expected, they may not have gone through as rigorous a QA process as usual. You might want to give them a whirl on non-production machines, or your virtual testing environment before sharing them with your users.

For more details on today’s Patch Day, check out the February bulletin summary now, or wait for our detailed, consolidated alerts which I’ll post on the blog through the day. — Corey Nachreiner, CISSP (@SecAdept).
