Last week a healthcare provider had its electronic health record system locked by ransomware; now a Zika virus email scam has been uncovered, showing the depths that some hackers and cybercriminals will stoop to in order to make a quick buck.
The latest email scam takes advantage of the public interest in the Zika virus epidemic in Brazil. Since April last year, the number of reported cases of Zika fever has grown. Zika fever is caused by the transmission of the Zika virus by Aedes mosquitos. Zika fever produces similar symptoms to Dengue fever, although the symptoms are often milder.
Scientists have also been alerted to a rise in the number of cases of microcephaly reported in Brazil. Microcephaly is a birth defect resulting in babies being born with a smaller than average head as well as other poor pregnancy outcomes. The rise in microcephaly has been linked to the increase in cases of Zika virus.
While no concrete evidence has been uncovered to suggest that pregnant women contracting Zika are likely to give birth to babies with microcephaly, there is concern that Zika can cause the birth defect. The World Health Organization (WHO) reports the virus has now spread to 23 countries. People are naturally worried. Women in Brazil and Columbia have been told to avoid becoming pregnant and hold off having children, while the government in El Salvador has told women not to get pregnant until 2018.
A potentially global health issue such as Zika is naturally a worry for any woman looking to start a family, and understandably the latest news about the virus is likely to be read. Scammers have been quick to take advantage of the media interest, and a scam has been developed to take advantage and infect computers with malware
Zika Virus Email Scam Delivers JS.Downloader Malware
The Zika virus email scam is currently doing the rounds in Brazil and is being sent in Portuguese. The Zika virus email scam appears to have been sent from Saúde Curiosa (Curious Health), which is a legitimate health and wellness website in Brazil. The email contains an attachment infected with JS.Downloader. JS. Downloader is a malware that is used to download malicious malware to infected users’ devices.
The subject line of the email is “ZIKA VIRUS! ISSO MESMO, MATANDO COM ÁGUA!” which translates as Zika Virus! That’s Right, killing it with water!” The email tells the recipient to click on the link contained in the email to find out how to kill the mosquitos that carry the virus, although the email also contains a file attachment which the email recipient is urged to open. Doing so will install the malware onto the user’s device. The link directs the user to Dropbox with the same outcome.
Anyone receiving an unsolicited email with advice about the Zika virus, regardless of the language it is written in, should treat the email with suspicion. This is unlikely to be the only Zika virus email scam sent by cybercriminals this year. With the Olympics taking place in Brazil in the summer, criminals are likely to use topics such as the Zika virus to spread malware.
If you want information about Zika, check the WHO website. If you receive an Zika virus email, delete it and do not click on any links in the email or open any attachments.
