Cybersecurity firm Trustwave has put a recent phishing campaign appearing to be from Kiwi company Xero under the spotlight.
In a blog last week, researchers from SpiderLabs Blog spotted the campaign, which started on August 16.
Scammers used genuine-looking emails with a xeronet.org domain name and sender details listed as Xero Billing Notifications.
The xeronet.org domain was registered in China on the same day of the campaign launch. Xero’s official domain name is xero.com.
The emails appeared to offer a subscription invoice for the previous billing period, and a link to the supposed invoice.
While the invoice link redirects to the malicious website, other links in the email point to the genuine Xero.com website, researchers explain.
When the ActiveX WScript Shell object launches the payload, users may witness its execution like any Windows binary.
Researchers say the malware first analyses the operating system, users and applications installed on the infected machine. It then changes policies for a number of system setting and Internet Explorer.
“Dridex is designed to steal banking and personal information by injecting itself into web browsers such as Firefox, Chrome and Internet Explorer. It monitors browsing activity and steals sensitive information for target online banks listed in its configuration file,” researchers explain.
“The malware communicates with several hosts over different ports using SSL. The use of encrypted channels for communication over nonstandard ports adds to the sophistication of the malware,” they continue.
But the attackers aren’t just behind one particular Xero scam. Researchers suspect attackers have also used xeroaccounting.org, quickbooks-support.biz, australiangovernments.com and myobaustralia.org.
Australian firm MYOB was also the subject of a phishing spoof, shortly after the Xero campaign was launched.
In June, MYOB was spoofed in a similar phishing campaign. The company’s COO, Andrew Birch, said that the company was making every effort to bring the fake website down.
“It’s important that people stay alert and consider their safety online. This includes checking the authenticity of invoices, and calling the vendor if in any doubt,” he said at the time.
“We’d also like to remind people to ensure they have good anti-virus protection installed, make sure their software is up-to-date and they have firewalls in place.”
