What is Ransomware? Ransomware is a type of malicious software that prevents users from accessing their computer system or files until a sum of money (ransom) is paid. In the malware landscape, ransomware has earned itself a well-deserved nasty reputation. There are two types of ransomware identified in this branch of the malware family tree; 1) locker ransomware and 2) crypto ransomware Locker ransomware effectively locks Windows access preventing the user from accessing their desktop or files.

Apple iOS and Email Attachment Encryption: A Question of Compliance

UPDATED: 7/1/2014 Apple has released iOS 7.1.2 which is supposed to resolve the issue where a user can access unencrypted mail attachments.  We recommended updating all Apple mobile devices as soon as possible. It was reported a few days ago by Andreas Kurtz, that since iOS 7.0.4  and including the most recent Apple iOS 7.1.1 email attachments using the native mail clients are not encrypted.  He was able to access these files even though the device's disk is encrypted.  What does this mean for compliance?  How many users are emailing patient information (HIPPA), finance data or other protected data thinking that their devices [...]

Leave no stone un-turned when patching Heartbleed

Most people are now up to speed about the existence of Heartbleed, but new information is coming out that the focus has only been on server side exploits.  Meldium, released a blog post titled Testing for "reverse" Heartbleed.  According to Meldium, "While patching our systems for the recent Heartbleed vulnerability, we found that some sites (including huge web properties), which had patched their servers were still vulnerable to a variant of the attack that we're calling "reverse heartbleed."  They have also released a tool to test this. What does this mean? Basically it means that OpenSSL patching can't stop just at servers [...]

Check to see if you are vulnerable. (Adrian Hayter, a consultant with CNS Hut3, revealed a proof of concept that many of the testing tools have bugs themselves) Check your public facing websites for the vulnerability.  Use one of these tools: SSLLabs Check internet facing equipment to see if it [...]

The Heartbleed Bug

The Heartbleed Bug is a recently discovered critical vulnerability found in widely used open-source implementations of the SSL/TLS protocols, OpenSSL .  SSL/TLS is used to provide security and privacy in many internet applications such as email, instant messaging, VPN, and secure web pages. The vulnerability was the result of an implementation problem (or a program mistake) in OpenSSL, which has left a large amount of private data exposed to the internet.  Most people are likely to be directly, or indirectly affected by this bug due to OpenSSL being the most popular cryptographic library and transport layer security currently in use [...]
