Check Point Research reveals that Emotet is now the seventh most prevalent malware, and its return is deemed “extremely concerning.” Trickbot once again in first place. Education and Research still top hackers’ target list.

Our latest Global Threat Index for November 2021 reveals that while Trickbot remains at the top of the most prevalent malware list, affecting 5% of organizations worldwide, the recently resurgent Emotet is back in the index in seventh position. CPR also reveals that the most attacked industry is Education/Research.

Despite major efforts from Europol and numerous law enforcement agencies earlier this year to bring down Emotet, the notorious botnet was confirmed to be back in action by November and is already the seventh most utilized malware. Trickbot tops the index for the sixth time this month, and is even involved with the new variant of Emotet, which is being installed on infected machines using Trickbot’s infrastructure.

Emotet is being spread via phishing emails which contain infected Word, Excel, and Zip files that deploy Emotet on the victim host. The emails contain intriguing subject lines such as current news events, invoices, and fake corporate memos to lure the victims to open them. Most recently, Emotet also started spreading through malicious Windows App Installer packages pretending to be Adobe software.

Emotet is one of the most successful botnet in the history of cyber and is responsible for the explosion of targeted ransomware attacks that we have witnessed in recent years. The botnet’s comeback in November is extremely concerning as it may lead to a further increase in such attacks. The fact that it is using Trickbot’s infrastructure means it is shortening the time it would take for Emotet to build a significant enough foothold in networks around the world. As it is being spread via phishing emails with malicious attachments, it’s crucial that user awareness and education is at the top of organizations’ priority lists when it comes to cybersecurity. And anyone looking to download Adobe software should remember, as with any application, to only go via official means.

CPR also revealed this month that Education/Research is the most attacked industry globally, followed by Communications and Government/Military. “Web Servers Malicious URL Directory Traversal” is still the most commonly exploited vulnerability, impacting 44% of organizations globally, followed by “Web Server Exposed Git Repository Information Disclosure” which affects 43.7% of organizations worldwide. “HTTP Headers Remote Code Execution” remains in third place in the top exploited vulnerabilities list, with a global impact of 42%.
