Clever SEO Spam Injection

Clever SEO Spam Injection

It’s very common for us here at Sucuri to face SEO injections on almost any type of CMS-based site. Today, I’ll be presenting how one particularly ingenious malware manages to hide so well inside a WordPress website.

The Traditional Approach

There are two common approaches attackers use to inject SEO spam on websites:

  1. Injecting HTML code for concealed elements in theme files
  2. Injecting fake spam posts in the WordPress database

Both approaches are readily found during Sucuri’s routine remediation process.

Fake Volkswagen Campaign Spreads Through Social Networks

Fake Volkswagen Campaign Spreads Through Social Networks

We recently investigated a suspicious link received by one of my colleagues on WhatsApp. The message (in Portuguese) states that Volkswagen is offering 20 free cars until the end of the year, and directs users to participate on a site that has been apparently crafted especially for this “event”.

After an initial investigation, it became clear that something was not right with the site. Several security vendors blacklisted it as a phishing site–although fishy, none of the classic phishing characteristics were present.

Localization and Customization of Credit Card Stealing Malware

Localization and Customization of Credit Card Stealing Malware

Credit card stealing malware is becoming more and more customized. We’ve been regularly seeing injected scripts with URLs that either mimic or include a portion of the victim’s site domain. Sometimes the injected code also references the victim’s site.

Recently, we’ve come across another level of customization.

Fake Payment Form in Bulgarian

A compromised Magento site had the following script injected into its core_config_data table.

hxxps://elegrina[.]com/assets/<domain>.js,  where <domain> was the second-level domain of the infected site.

What is Phishing?

What is Phishing?

Phishing is a serious threat to any industry. We have seen this topic appear in the news more each day. You might have already received a fraudulent email from what seemed to be your bank or even seen the hacking that took place during the 2016 US presidential election. But what do you know about phishing?

What is Phishing?

Phishing is the fraudulent attempt to obtain sensitive information like login information or other personal identification information (PII), which is any data that could potentially identify a specific individual, such as:

  • usernames,
  • passwords,
  • credit card details,
  • SSN (Social Security Number),
  • bank account information,
  • email,
  • phone number,
  • secret question answers

Even partial information can increase the chances of success to subsequent social engineering attacks.

Fear, Uncertainty, and Doubt

Fear, Uncertainty, and Doubt

There’s a term for the practice of scaring potential customers into purchasing products or services they don’t need: FUD; fear, uncertainty, and doubt. This practice is widespread in the computer/IT industries at large, but is especially present in the security industry.

People don’t want to get hacked—but may also not understand the issues and forces at play. This makes them easy targets for overzealous sales representatives who see an opportunity to use misinformation to increase their paycheck via commission payouts.

Navigating Data Responsibility

Navigating Data Responsibility

As we take a step back and think about how much the Internet has grown over the past 20 years, we realize how much content/data has been made available to everyone.

Moving forward, there’s no reason to expect data availability to slow down. In fact, insideBIGDATA claims:

There are many sources that predict exponential data growth toward 2020 and beyond. Yet they are all in broad agreement that the size of the digital universe will double every two years at least, a 50-fold growth from 2010 to 2020.

A Scam-Free Cyber Monday for Online Businesses

A Scam-Free Cyber Monday for Online Businesses

Every year we see an increase in website attacks during the holidays. 

While business owners see their sales go up due to promotional Black Friday and Cyber Monday campaigns, hackers are in the background working nonstop to create malicious, fraudulent websites as well as take advantage of legitimate ones.

Main Cyber Monday Threats
Phishing Pages

One of the major risks to consumers is phishing campaigns.

Carefully crafted phishing login pages convince users they are logging into a valid service.

PCI for SMB: Requirement 9 – Implement Strong Access Control Measures

PCI for SMB: Requirement 9 – Implement Strong Access Control Measures

Welcome to the sixth post of a series on understanding the Payment Card Industry Data Security Standard–PCI DSS. We want to show how PCI DSS affects anyone going through the compliance process using the PCI SAQ’s (Self Assessment Questionnaires).

In the previous articles written about PCI, we covered the following:

  • Requirement 1: Build and Maintain a Secure Network – Install and maintain a firewall configuration to protect cardholder data.
  • Requirement 2: Build and Maintain a Secure Network – Do not use vendor-supplied defaults for system passwords or other security parameters.

Real-Time Fine-Tuning of the WAF via API

Real-Time Fine-Tuning of the WAF via API

Though the Sucuri Firewall is simple to set up and protects your website immediately, it’s possible to have granular control of the WAF by using an API.

For instance, there’s a specific filter inside the WAF dashboard called Emergency DDoS. This filter basically increases the strength of the DDoS protection to an “emergency” level where most non-human access is blocked.

API to Boost Firewall Protection

The Firewall API is mostly used for whitelisting and clearing the website cache.

Hackers Change WordPress Siteurl to Pastebin

Hackers Change WordPress Siteurl to Pastebin

Last Friday, we reported on a hack that used a vulnerability in the popular WP GDPR Compliance plugin to change WordPress siteurl settings to erealitatea[.]net. At that time it was not clear who was behind the massive attack, since the erealitatea[.]net domain didn’t work and the infection simply broke the compromised sites. Our SiteCheck scanner detected the infection on about 700 sites over the weekend and PublicWWW now currently returns 573 results.

Web Marketers Should Learn Security

Web Marketers Should Learn Security

Most online marketers think of themselves as T-shaped individuals. The theory behind this concept is that individuals possess a wide range of skills, with some abilities running deeper than others.

Website security awareness is in short supply and we need more champions — especially among small and medium-sized businesses. Digital marketers are in a prime position to add security know-how to their diverse toolkit.

It makes sense for marketers to want to secure their websites.
