When implementing COVID-19 business continuity plans, companies should take into consideration security threats from cybercriminals looking to exploit fear, uncertainty and doubt – better known as FUD. Fear can drive a thirst for the latest information and may lead employees to seek online information in a careless fashion – leaving best practices by the wayside.
According to Reinsurance News, there has already been “a surge of coronavirus-related cyber attacks”. Many phishing attacks “have either claimed to have an attached list of people with the virus or have even asked the victim to make a bitcoin payment for it.” Not all employees are accustomed to the risks from a corporate-wide work from home (WFH) policy given the previous lack of intersection between work and personal computers.
One cyber security firm released information outlining these WFH risks. And, another security provider offers a common-sense refresher: “If you get an email that looks like it is from the WHO (World Health Organization) and you don’t normally get emails from the WHO, you should be cautious.” In addition to recommendations made by security consultants, there are privacy-forward recommendations that will necessarily mitigate against phishing exploits. For example, WFH employees should be steered towards privacy browsers such as Brave and Firefox to avoid fingerprinting and search engines such as Duckduckgo for private searches. A comprehensive listing of privacy-forward online tools is found at PrivacyTools.IO.
Criminals have already exploited the current FUD by creating very convincing COVID-19-related links. As reported by Brian Krebs, several Russian language cybercrime forums now sell a “digital Coronavirus infection kit” that uses the Hopkins interactive map of real-time infections as part of a Java-based malware deployment scheme. The kit only costs $200 if the buyer has a Java code signing certificate and $700 if the buyer uses the seller’s certificate.
At a very basic level, WFH employees should be reminded not to click on sources of information other than clean URLs such as CDC.Gov or open unsolicited attachments even if they appear coming from a known associate. Now that banks, hotels, and health providers are sending emails alerting their clients of newly-implemented COVID-19 procedures, it is especially easy to succumb to spear phishing exploits – which is the hallmark of state-sponsored groups. As recently reported, government-backed hacking groups from China, North Korea, and Russia have begun using COVID-19-based phishing lures to infect victims with malware and gain infrastructure access. These recent attacks primarily targeted users in countries outside the US but there should be little doubt more groups will focus on the US in the coming weeks. Until ramped up testing demonstrates that the COVID-19 risk has passed, companies are well advised to focus some of their security diligence on these targeted attacks.
This does not mean employees need to be fed yet more FUD – this time regarding network security, without some good news. Employees can be reminded of the fact a decade ago we survived a much worse pandemic. Specifically, between April 2009 and April 2010, there were 60.8 million cases, 274,304 hospitalizations, and 12,469 deaths in the United States caused by the Swine Flu. Globally, the Swine Flu infected between 700 million and 1.4 billion people, resulting in 150,000 to 575,000 deaths. Moreover, the young were a vector for Swine Flu yet are not for COVID-19. And, the band of 25 – 35 year olds are better in two days – hardly a bad cold, for COVID-19 whereas there was no such band for the Swine Flu. On the downside, COVID-19 has a slightly more efficient transmission mechanism than Swine Flu.
Even though we are now on the whole facing a much lesser evil than the Swine Flu we remain exponentially more alarmed and have been withdrawing en mass from social interactions. This is obviously not a good thing but our current pandemic panic should pass by mid-April. Until then, we can continue downing the hottest drink in town just to be on the safe side.
