While organised crime volumes remain broadly constant, there has been a shift to Covid-19 themed phishing campaigns and fraudulent websites as organised crime groups seek to monetise the fear, uncertainty and doubt many people feel during the pandemic.


Financial Scams

A wide range of COVID-19 related financial scams are in progress:

— Threat actors are exchanging US taxpayer’s data on underground forums to claim coronavirus-relief stimulus checks and income tax refunds, with some actors discussing to partner up for further frauds, Secureworks reports.

— Resurgence of the Zeus Sphinx banking trojan, with version updates and core modifications with coronavirus as a theme, increasing its potency and persistence in targeting North American banks by harvesting credentials from online banking sessions, Security Intelligence reports.

— Grandoreiro malware targeting banks in Spain using COVID-19 themed videos tricking users to run a concealed executable, infecting devices with a remote-access tool to empty their bank accounts, Security Intelligence reports.

— A new version of Lampion trojan is being distributed via email, with lures containing fake telco invoices, fake invoices of bank transactions and emergency funds from the Portuguese government, Seguranca Informatica reports.

Infrastructure

Organised crime groups have been building out attack infrastructure to affect corporations: 

— Her Majesty’s Revenue and Customs (HMRC) has asked ISPs to remove 292 scam websites exploiting COVID-19 outbreak, Info Security reports.

— 300 coronavirus-themed malware samples were communicating with 20 suspicious domains. Between March 1 and April 7, 2020, these 20 domains made 453,074 unique network connections across 27 unique cloud environments, Unit 42 reports.

— An anonymous hacker has released a code that allows individuals to submit junk data to the Ohio state’s ‘COVID-19 fraud’ site. The circulated script makes it harder for submissions to be investigated, Vice reports.

Phishing and Malware

Broader phishing and malware campaigns continue to exploit COVID-19 themed lures for credential theft, ransomware and business email compromise (BEC):

— Australian global logistics firm Toll Group confirmed it was hit with the ransomware variant Nefilim, which uses AES-128 encryption to lock files and blackmail payments made via email, ZDNet reports.

— A range of different malware used in a variety of coronavirus-themed attacks has been found to be a type of infostealer, including Lokibot, Agent Tesla and more, Lastline reports.

Healthcare

Healthcare is a growing target for cybercrime activity, with organisations involved in research into COVID-19 being at heightened risk:

— Europe’s largest private hospital operator hit by ransomware attack using a variant called Snake, disrupting operations globally, KrebsOnSecurity reports.

— US FBI issued a state espionage warning against US research institutions to steal intellectual property related to drug and vaccine development.

— Iranian linked hackers targeted a major US drugmaker with a fake email login page sent to a top executive to steal passwords, Reuters reports.

Conferencing Platforms

While attacks still involve phishing linked to the delivery of malware, a range of other exploitation techniques are being attempted targeting the use of conferencing platforms:

— Attackers are targeting video conference users by impersonating an email notification from the provider stating the user has missed a scheduled meeting and asks to click a link which redirects to a fake Microsoft login page to steal credentials, Abnormal Security reports.

— Multiple vulnerabilities in Accusoft ImageGear, an image processing software, with one being able to execute remote code on a victim’s machine, Cisco Talos reports.

— Citrix has issued a security update for multiple vulnerabilities in their ShareFile storage system, with successful exploitation leading to unauthorised access to user’s files.

— Threat Post reports Microsoft has released fixes for 111 security vulnerabilities in May’s patch update, with 56 fixes being elevation-of-privilege (EoP) bugs. Patches include:
    - CVE-2020-1056: Critical Microsoft Edge EoP bug, allowing the attacker to access information from one domain and inject it into another.
