Online criminals are targeting individuals and businesses that advertise via Google Ads by phishing them for their credentials — ironically — via fraudulent Google ads.
The scheme consists of stealing as many advertiser accounts as possible by impersonating Google Ads and redirecting victims to fake login pages. We believe their goal is to resell those accounts on blackhat forums, while also keeping some to themselves to perpetuate these campaigns.
This is the most egregious malvertising operation we have ever tracked, getting to the core of Google’s business and likely affecting thousands of their customers worldwide. We have been reporting new incidents around the clock and yet keep identifying new ones, even at the time of publication.
First publicly reported in 2018, DarkGate is a Windows-based malware with a wide-range of capabilities including credential stealing and remote access to victim endpoints. Until recently, it was only seen being delivered through traditional email malspam campaigns. In late August 2023, however, researchers at Trusec found evidence of a campaign using external Teams messages to deliver the DarkGate Loader.
In recent weeks, we have noted an increase in malvertising campaigns via Google searches. Several of the threat actors we are tracking have improved their techniques to evade detection throughout the delivery chain.
We believe this evolution will have a real world impact among corporate users getting compromised via malicious ads eventually leading to the deployment of malware and ransomware.
In this blog post, we look at a malvertising campaign that seems to have flown under the radar entirely for at least several months. It is unique in its way to fingerprint users and distribute time sensitive payloads.
While the official conflict between Russia and Ukraine began in February 2022, there is a long history of physical conflict between the two nations, including the 2014 annexation of Crimea by Russia and when the regions of Donetsk and Luhansk declared themselves independent from Ukraine and came under Russia's umbrella. Given this context, it would not be surprising that the cybersecurity landscape between these two countries has also been tense.
