In a conversation with cybersecurity news portal TechCrunch, Simon Wijckmans, founder and CEO of the web security company c/side, said the hacking campaign is still “very much live”.
Spray and pray campaign
The hackers aim to distribute malware to loot passwords and sensitive data from Mac and Windows users. According to c/side, a few hacked websites rank among the most popular ones on the internet. Reporting on the company’s findings, Himanshu Anand believes it is a “widespread and very commercialized attack” and told TechCrunch the campaign is a “spray and pray” cyber attack targeting website visitors instead of a specific group or a person.
After the hacked WordPress sites load in a user’s browser, the content immediately turns to show a false Chrome browser update page, asking the website visitor (user) to download and install an update to access the website, researchers believe.
Users tricked via fake sites
When a visitor agrees to the update, the compromised website will ask the user to download a harmful malware file disguised as the update, depending on whether the visitor is a Mac or Windows user. Researchers have informed Automattic (the company) that makes and distributes Wordpress.com about the attack campaign and sent a list of harmful domains.
According to TechCrunch, Megan Fox, spokesperson for Automattic, did not comment at the time of press. Later, Automattic clarified that the security of third-party plugins is the responsibility of WordPress developers.
“There are specific guidelines that plugin authors must consult and adhere to ensure the overall quality of their plugins and the safety of their users,” Ms Fox told TechCrunch. “Authors have access to a Plugin Handbook which covers numerous security topics, including best practices and managing plugin security,” she added.
C/side has traced over 10,000 sites that may have been a target of this hacking campaign. The company found malicious scripts on various domains by crawling the internet, using a reverse DNS lookup to find domains and sites linked with few IP addresses which exposed a wider number of domains hosting malicious scripts. TechCrunch has not confirmed claims of C/side’s data, but it did find a WordPress site showing malicious content earlier this week.
