WordPress 4.7.5 Security Release – Immediate Update Recommended

A few hours ago WordPress abruptly released 4.7.5 which is a security release. It fixes six vulnerabilities which are detailed on the wordpress.org blog.

I’d like to encourage you to update to 4.7.5 as soon as possible. Unless you have disabled automatic updates, your site may have already been upgraded to WordPress 4.7.5. This security release was a ‘minor’ release and WordPress by default automatically updates core minor releases.

I have used the term ‘abrupt’ to describe this release because it went out without much pre-announcement. I’m concerned that this release may have fixed more than the vulnerabilities that have been detailed on the WordPress blog. That would not be without precedent.

New WannaCry Ransomware and How to Protect Yourself

This is another Wordfence public service announcement (PSA) that describes new WannaCry ransomware variants that have emerged in the past few hours and describes how to protect yourself against the WannaCry ransomware, also known as the WannaCrypt ransomware. We occasionally send out alerts that are outside the WordPress space when we feel that they are in the interests of our WordPress publishers and the broader global community. This is, unfortunately, one of those alerts.

How to protect yourself against WannaCry ransomwareOn Friday we alerted you to a global ransomware campaign a few hours after it started. That campaign has now infected over 10,000 organizations and 200,000 individuals in 150 countries. This includes the UK National Health System which saw ambulances divert from affected hospitals.

Massive Global Ransomware Attack Underway, Patch Available

This is a Wordfence public service security announcement for all users of computers running any version of Windows.

We have confirmed that a serious virulent ransomware threat known as WannaCrypt0r/WannaCry has affected Windows computers on shared networks in at least 74 countries worldwide, with 57,000 reported individual cases being affected. And according to the analysis team at Kaspersky Lab, that number is growing fast.

Once one computer on a network is affected, the malware infection easily spreads to other Windows computers on the same network, shutting down entire government agencies and national infrastructure companies. Hospitals across the UK were being forced to divert patients and ambulance routes as of Friday afternoon, and several utility companies across Europe reported infection across their computer networks according to BBC News.

22 Abandoned WordPress Plugins with Vulnerabilities

As an interesting research project, Pan Vagenas, one of our researchers, took a closer look at abandoned plugins in the WordPress repository. His work was inspired by a recent post by Isabel Castillo where she lists the oldest abandoned plugins in the WordPress plugin repository.

An abandoned plugin is one that has not been updated for several years. According to Isabel’s post there are several plugins that have a large install base that haven’t been updated for some time:

“Exec-PHP plugin by Sören Weber has over 100,000 active installs despite that it has not been updated since June of 2009. Category Order by Wessley Roche has over 90,000 active installs even though it was last updated in May of 2008. Ultimate Google Analytics by Wilfred van der Deijl has over 80,000 installs even though it was last updated more than nine years ago.”
