Cybercriminals constantly latch on to news items that captivate the public’s attention, but usually they do so by sensationalizing the topic or spreading misinformation about it. Recently, however, cybercrooks have started disseminating real-time, accurate information about global infection rates tied to the Coronavirus/COVID-19 pandemic in a bid to infect computers with malicious software.
A recent snapshot of the Johns Hopkins Coronavirus data map, available at coronavirus.jhu.edu.
In one scheme, an interactive dashboard of Coronavirus infections and deaths produced by John Hopkins University is being used in malicious Web sites (and possibly spam emails) to spread password-stealing malware.
Late last month, a member of several Russian language cybercrime forums began selling a digital Coronavirus infection kit that uses the Hopkins interactive map as part of a Java-based malware deployment scheme. The kit costs $200 if the buyer already has a Java code signing certificate, and $700 if the buyer wishes to just use the seller’s certificate.
“It loads [a] fully working online map of Corona Virus infected areas and other data,” the seller explains. “Map is resizable, interactive, and has real time data from World Health Organization and other sources. Users will think that PreLoader is actually a map, so they will open it and will spread it to their friends and it goes viral!”
The sales thread claims the customer’s payload can be bundled with the Java-based map into a filename that most Webmail providers allow in sent messages. The seller claims in a demonstration video that Gmail also allows it, but the video shows Gmail still warns recipients that downloading the specific file type in question (obscured in the video) can be harmful. The seller says the user/victim has to have Java installed for the map and exploit to work, but that it will work even on fully patched versions of Java.
“Loader loads .jar files which has real working interactive Coronavirus realtime data map and a payload (can be a separate loader),” the seller said in the video. “Loader can predownload only map and payload will be loaded after the map is launched to show map faster to users. Or vice versa payload can be predownloaded and launched first.”
It’s unclear how many takers this seller has had, but earlier this week security experts began warning of new malicious Web sites being stood up that used interactive versions of the same map to distract visitors while the sites tried to foist the password-stealing AZORult malware.
As long as this pandemic remains front-page news, malware purveyors will continue to use it as lures to snare the unwary. Keep your guard up, and avoid opening attachments sent unbidden in emails — even if they appear to come from someone you know.
