WordCamp San Diego – Kind of a Big Deal

This past weekend we found ourselves at WordCamp San Diego… and it was classy. This came as no surprise as the WordCamp theme was “Stay Classy,” a line taken from the comedy gem Anchorman set in the same city. SiteLock was a Gold sponsor (classy!) and along with our seasoned WordCamp goer Adam Warner, our own Web Security Consultant Managers, JC Bustillos and Evan Richardson, also attended the event.

SiteLock Threat Intercept

Fake WordPress SEO Plugin Provides Backdoor Access

We recently discussed a particularly sneaky piece of malware that’s been disguising itself as fake plugin and targeting Joomla! users. While this phenomenon is not unique to the Joomla! content management system, SiteLock has discovered a recent trending fake plugin for WordPress, one of the world’s largest open source applications.

WordCamp Atlanta 2017 – Setting a Gold Standard

This past weekend we found ourselves at WordCamp Atlanta, one of the largest WordCamps in the country. Because this event fell on the St. Patrick’s Day holiday, the theme was “Find your Pot of Gold with WordPress.” This theme was pervasive throughout the entire weekend, even the various speakers built this theme into their sessions!

SiteLock was lucky enough to sponsor the event (no pun intended) and Adam Warner, one of our staples in the WordPress community, had the pleasure of presenting his own story of finding WordPress.

AskSecPro: Feature-Based Malware Detection

Last year we published an #AskSecPro series where we explained how signature-based malware analysis works, as well as how traditional signatures are created. An area we don’t often talk about in public channels, but has played a pivotal role in SiteLock becoming a global leader in website security solutions, is our research and development efforts in new security technologies. In addition to our more traditional approaches to malware detection, SiteLock continues to explore new frontiers in technological improvement to push the field of security research forward. For some time SiteLock has been developing machine learning mechanisms as part of its process for discovering new malware iterations on an automatic basis. Our research in the field has shown that machine learning promises to be an important part of early malware detection and preliminary identification. One of the most significant breakthroughs we’ve had in machine learning as it pertains to malware detection and signatures, has been in feature-based signature analysis.

SiteLock Research shield

This article was co-authored by Security Researcher Wyatt Morgan from SiteLock Research.

 

This month we’ve seen WordPress websites bombarded with defacements and remote code execution attempts by abusing a vulnerability in the WordPress REST API. As could be expected, compromises motivated by financial gain have now made their debut through the same vector. This most recent flavor of defacements focuses on driving traffic to a rogue pharmacy website, where the visitor is encouraged to purchase — you guessed it, “authentic” erectile dysfunction medication.

Remote Code Execution Attempts via REST API Vulnerability

SiteLock Research shield

This article was co-authored by Security Researcher Wyatt Morgan from SiteLock Research.

 

In the continuing saga of the WordPress REST API vulnerability in WordPress 4.7 and 4.7.1, SiteLock has identified that at least one hacker has launched a campaign specifically attempting remote code execution (RCE) on WordPress websites. The attacks aim to take advantage of WordPress websites using plugins that enable PHP to run inside of posts. If successful, the attack injects a line of code that ultimately downloads a series of malicious files from a Pastebin repository. These malicious files are used to install  backdoors and automatically steal information from  websites. When unsuccessful at remote code execution, the attack overwrites existing posts and leaves behind PHP shortcode.

Ask a Security Professional: WordPress Database Security Part One — Anatomy of WordPress

For most people the year is still just getting started, but for some website owners the year has already packed quite a punch in the form of website attacks. This month hackers exploiting a vulnerability in the WordPress REST API successfully defaced over a million websites in what has become one of the largest website defacement campaigns to date. The attacks injected content that overwrote existing posts on WordPress websites running versions 4.7 and 4.7.1, leaving website owners with an immeasurable number of “Hacked by” posts across the droves of impacted websites.WordPress REST API

Many website owners who have unfortunately found themselves in the proverbial trenches of a digital battlefront, some of which had at least some security measures, are facing a difficult data recovery situation. It is from these recent events that the next Ask a Security Professional question was crafted; How can I better protect my data?

I feel that it’s important to fully understand what the problem is in order to best understand what forms a solution can take. In Part One of #AskSecPro we’ll cover an introduction to some of the infrastructure behind WordPress. Let’s start at the beginning.
