Antiviren-Software zum Schutz vor Ransomware … die Definition von Wahnsinn?

Posted by: Alex Kurz  /  16 May 2017 13:54:44 BST

In Bezug auf den kürzlich erfolgten globalen Ransomware-Angriff hielten wir es für eine gute Idee, diesen Blog vom 18. April aus dem Englischen zu übersetzen und auch hier zu posten.

Die Geschwindigkeit, mit der sich Ransomware verbreitet, ist überwältigend. Das SonicWall Global Response Intelligence Defense (GRID) Network hat 2015 etwa 3,8 Millionen Angriffe verzeichnet. Im vergangenen Jahr stieg diese Zahl auf 638 Millionen Attacken an. Sie haben richtig gelesen – 638 Millionen! Das sind gut 167 Mal so viele Angriffe wie 2015. Wow! Dabei liegen die Gründe für diese Entwicklung auf der Hand. Es ist ein sehr profitables Geschäft! Ransomware ist eine Klasse von Schadprogrammen, die Ihre Daten verschlüsseln und „Lösegeld“ für die Entschlüsselung verlangen. Die moderne Version von „Geld oder Leben!“ sozusagen.

Was ist also die Antwort? Antiviren-Software, Antiviren-Software und noch mehr Antiviren-Software?

As I’m sure you already know, Friday, 15 May, saw the beginning of a global ransomware attack, hitting hundreds of thousands of businesses around the world. Like most companies, we have taken stock of the situation and sent some simple instructions to our staff so that we can avoid becoming infected.


We would like to share these with you, but before we do that, we cannot stress highly enough the importance of having a good email scanning system in place to avoid malicious content ending up mailboxes and web filters to block dangerous sites in your browsers.

The Heads Up: Solving Ransomware with AV...the definition of insanity?

Posted by: Alex Kurz  /  18 April 2017 10:00:00 BST

 

In the light of the recent global ransomware cyber attack, we felt it appropriate to repost this blog for your information. The original post was dated 18 April, 2017.

The speed at which ransomware is proliferating is mind blowing. In 2015, SonicWall’s Global Response Intelligence Grid recorded around 3.8 million attacks. By last year, that had grown to 638 million. Yes, you read it right – 638 million! That’s a staggering 167 times the number of attacks in 2015. Wow! And it’s easy to see why. Ransomware is particularly profitable for hackers. It’s a nasty type of malware that holds your data hostage by encrypting it and then asking you to pay for a decryption key. Stand and deliver on steroids.

So, what’s the answer? AV, AV and more AV?

Cloud Security - how is 2017 shaping up?

Posted by: Ed Macnair  /  07 February 2017 09:42:36 GMT

With January rapidly becoming a distant memory, and as all those New Year good intentions get left by the wayside, I am pleased to report the race to the cloud continues apace.

But as enterprises embrace the cloud to help their businesses become more agile and responsive, they invariably encounter more security threats and become more susceptible to breaches from multiple channels. Legacy security technologies simply lag behind, as they just weren’t designed to deal with these threats.

So in this complex world, what do we think are the big up and coming cloud security trends? Here we take a look at our top five…

Cloud Security issues aren’t unknown

Posted by: Ed Macnair  /  19 December 2016 11:43:51 GMT

When Cloud was the new kid on the block, the risk of adoption was simply too variable and therefore untenable but that didn’t really matter. It was gathering such momentum the security market simply couldn’t keep up. So in line with tradition, the easiest option was to get the big red stamp out and mark it ‘unsafe’ and hope it would go away.

Behaving Badly

As any law-enforcement advisor will tell you, criminals succeed mainly because they understand the human psyche. Knowing how to manipulate somebody into leaving a backdoor open is still the ultimate weapon in any criminal’s arsenal.

Here phishy, phishy

Posted by: Ed Macnair  /  19 December 2016 10:58:04 GMT

The thing about well known phishing scams is they’ve essentially become industry-comedy punch lines which also puts them in danger of being diluted as a meaningful and growing threat.

If you even so much as mention to a colleague the Nigerian Prince offering you many many monies to leave the country, you will instantly engage in a series of one-upmanship debates on who’s received the most spurious spam.

Two’s company but it’s no longer enough

Cyber Security is now well and truly on the map. Politicians wax lyrical about how they’re fighting it, entire supplements of every major Sunday newspaper are dedicated to it and in general, the world is that little bit more savvy, I’m delighted to say.
