Pacemakers prone to getting hacked

Recently the The FDA and Homeland Security have issued alerts about vulnerabilities in 4,65,000 pacemakers. The devices can be remotely “hacked” to increase activity or reduce battery life, potentially endangering patients. Feasible vulnerabilities: Absence of memory and encryption: In such embedded devices there is a lack to support proper cryptographic e

Need-to-Know Only: Use Encryption to Make Data Meaningless to Prying Eyes

Organizations continue to be plagued by data breaches, and data is leaking from our enterprises in large quantities. However, data leakage is not the only issue. The problems — namely, regulatory fines, brand damage and lost revenue — begin when sensitive data that is readable and accessible falls into the wrong hands. Despite these concerns, security profes

The Power of Pervasive Encryption

The new z14 mainframe computer offers a chance to re-evaluate what a mainframe can do for an organization. Gone are the days when the mainframe was the only way to do computing. Today, there are new and different choices, and the z14 can make those choices practical. The z14 features standard improvements that users have come to expect, such as faster, mor

Downgrading RDP connections and how to avoid it

This post describes how Remote Desktop Protocol (RDP) connections can be vulnerable to a downgrade attack if Terminal Servers are configured insecurely. We’re not aware of this issue being discussed before – googling only found pages about installing an earlier version of the RDP client, not about downgrading the protocol in the way described her

Basics of Cryptography: the practical application and use of cryptography

Cryptography originated about 4000 years ago, and the world of cryptography has evolved a lot since then. Today ‘Cryptography’ is omnipresent in our lives without most of us realizing it. The fundamental aspect of ‘Cryptography’ has remained the same through time which is to hide information in transit and make it available only

HTTPS crypto’s days are numbered. Here’s how Google wants to save it

Like many forms of encryption in use today, HTTPS protections are on the brink of a collapse that could bring down the world as we know it. Hanging in the balance are most encrypted communications sent over the last several decades. On Thursday, Google unveiled an experiment designed to head off, or at least lessen, the catastrophe.In the coming months, Goog

Experts crack nasty ransomware that took crypto-extortion to new heights

A nasty piece of ransomware that took crypto-extortion to new heights contains a fatal weakness that allows victims to decrypt their data without paying the hefty ransom.When it came to light two weeks ago, Petya was notable because it targeted a victim's entire startup drive by rendering its master boot record inoperable. It accomplished this by encrypting
