As the world comes to grips with the coronavirus pandemic[1], the situation has
proven to be a blessing in disguise for threat actors, who’ve taken
advantage of the opportunity to target victims with scams or
malware campaigns.

Now, according to a new report published by Check Point Research
today and shared with The Hacker News, hackers are exploiting the
COVID-19 outbreak to spread their own infections, including
registering malicious Coronavirus-related domains and selling
discounted off-the-shelf malware in the dark web.

“Special offers by different hackers promoting their ‘goods’ —
usually malicious malware or exploit tools — are being sold over
the darknet under special offers with ‘COVID19’ or ‘coronavirus’ as
discount codes, targeting wannabe cyber-attackers,” the
cybersecurity firm said.

COVID-19 Discounts: Exploit Tools for Sale

The report comes following an uptick in the number of malicious
coronavirus-related domains
[2]
that have been registered since the start of January.

“In the past three weeks alone (since the end of February 2020), we
have noticed a huge increase in the number of domains registered —
the average number of new domains is almost 10 times more than the
average number found in previous weeks,” the researchers said. “0.8
percent of these domains were found to be malicious (93 websites),
and another 19 percent were found to be suspicious (more than 2,200
websites).”

Some of the tools available for purchase at a discounted price
include “WinDefender bypass” and “Build to bypass email and chrome
security.”

Another hacking group, which goes by the moniker “SSHacker,” is
offering the service of hacking into Facebook account for a 15
percent discount with “COVID-19” promo code.
What’s more, a seller that goes by the name of “True Mac” is
selling a 2019 MacBook Air model for a mere $390 as a “corona
special offer.” It goes without saying the offer is a scam.

A Long List of Coronavirus-Themed Attacks

The latest development adds to a long list of cyberattacks against
hospitals[3]
and testing
centers
[4], distribute malware such
as AZORuIt[5], Emotet[6], Nanocore
RAT
[7] and TrickBot[8] via phishing campaigns
using malicious
links
[9] and attachments, and
execute malware and ransomware
attacks
[10] that aim to profit off
the global health concern.

  • APT36, a Pakistani state-sponsored threat actor that targets
    the defense, embassies, and the government of India, was found
    running a spear-phishing campaign using Coronavirus-themed document
    baits that masqueraded as health advisories to deploy the Crimson Remote
    Administration Tool
    [11] (RAT) onto target
    systems.
  • Researchers from security firm IssueMakersLab[12] uncovered a malware
    campaign launched by North Korean hackers that used boobytrapped
    documents detailing South Korea’s response to the COVID-19 epidemic
    as a lure to drop BabyShark malware. Recorded
    Future
    [13] observed, “at least
    three cases where reference to COVID-19 has been leveraged by
    possible nation-state actors.”
  • A COVID-19-themed malspam
    campaign
    [14] targeting the
    manufacturing, industrial, finance, transportation, pharmaceutical,
    and cosmetic industries via Microsoft Word documents that exploits
    a two-and-a-half-year-old Microsoft Office bug in Equation Editor
    to install AZORult malware. The AZORult info stealer has also been
    distributed using a fraudulent version of the Johns Hopkins
    Coronavirus Map
    [15] in the form of a
    malicious executable.
  • A fake real-time coronavirus tracking Android app, called
    COVID19
    Tracker
    [16],” was found to abuse
    user permissions to change the phone’s lock screen password and
    install CovidLock
    ransomware
    [17] in return for a $100
    bitcoin ransom.
  • Another phishing attack, uncovered by Abnormal
    Security
    [18], targeted students and
    university staff with bogus emails in a bid to steal their Office
    365 credentials by redirecting unsuspecting victims to a fake
    Office 365 login page.
  • Comment spamming
    attacks
    [19] on websites that
    contained links to a seemingly innocuous coronavirus information
    website but redirected users to dubious drug-selling
    businesses.
  • Aside from malware-laden spam emails, F-Secure
    researchers
    [20] have observed a new
    spam campaign that aims to capitalize on the widespread mask
    shortage to trick recipients into paying for masks, only to send
    them nothing.

Staying Secure in the Time of COVID-19

It’s amply that these attacks exploit coronavirus fears and
people’s hunger for information about the outbreak. Given the
impact on the security of businesses and individuals alike, it’s
essential to avoid falling victim to online scams and practice good
digital hygiene:

  • Businesses should ensure that secure remote
    access technologies
    [21] are in place and
    configured correctly, including the use of multi-factor
    authentication, so that employees can conduct business just as
    securely from home.
  • Individuals should keep away from using unauthorized personal
    devices for work, and ensure “personal devices
    will need to have the same level of security
    [22] as a company-owned
    device, and you will also need to consider the privacy implications
    of employee-owned devices connecting to a business network.”
  • Watch out for emails and files
    received from unknown senders
    [23]. Most importantly,
    check a sender’s email address for authenticity, don’t open unknown
    attachments or click on suspicious links, and avoid emails that ask
    them to share sensitive data such as account passwords or bank
    information.
  • Use trusted sources, such as legitimate
    government websites
    [24] — for up-to-date,
    fact-based information about COVID-19.
