Threat Actor mentions in Critical Infrastructure

Time Series

This chart shows the trending Threat Actors related to Critical Infrastructure over the last week.

Weekly Industry View

Industry Information
Retail & Hospitality Sucuri researchers observed a Magento 2 store compromise which used a malicious injection to capture POST data from site visitors on the checkout page. The injection encoded the captured data and saved it to a JPG file. According to the researchers, this allowed the attacker to keep the stolen data in a seemingly benign file and download it at their convenience. The injection could capture information submitted on the checkout page, including full names and addresses, payment card details, telephone numbers, as well as email addresses if the user was logged in.
Government Cofense researchers observed a new email phishing campaign impersonating the US Internal Revenue Service. The email references an application form for the American Rescue Plan and asks the user to download an Excel spreadsheet from Dropbox. Upon opening, the user is asked to enable macros. The researchers note that the macros do not directly download malware or run a PowerShell script, but instead drop an XSL file to disk and then use a WMI query to obtain system information. JavaScript contained in the XSL file is then executed via WMI and the banking trojan Dridex is downloaded.
Critical Infrastructure McAfee researchers observed a new espionage campaign, dubbed Operation Diànxùn, targeting telecommunications companies in Southeast Asia, Europe and the US. A strong interest in German, Vietnamese and Indian companies was identified. The initial attack vector is not known at present but believed to be via an attacker-controlled domain, with phishing websites masquerading as the Huawei company career page likely used. The final payload includes a backdoor for remote control and Cobalt Strike Beacon. The techniques used in the campaign resemble previous campaigns by RedDelta and Mustang Panda, though no use of PlugX was observed. The researchers assess with medium confidence that the campaign is related to the current ban of Chinese technology in the global 5G roll-out.
Technology Kaspersky researchers warned that threat actors responsible for the Lemon_Duck crypto mining botnet are ‘massively hitting’ vulnerable Microsoft Exchange Servers via ProxyLogon exploits. Following exploitation, the group downloads malicious payloads onto servers via web shells. Huntress Labs also identified indicators of compromise linked to the malware, which installs XMRig Monero CPU miners on devices, while examining Microsoft Exchange Server exploitation.
Education On March 16th, 2021, the Federal Bureau of Investigation (FBI) warned education institutions in the UK and US of a rise in PYSA ransomware attacks. The FBI stated that the attackers have been targeting K-12 schools, seminaries, and higher education institutions. The threat actors often gain initial access via Remote Desktop Protocol attacks and phishing before using tools such as PowerShell Empire, Mimikatz, and Koadic for further access. Prior to encrypting files, the attackers exfiltrate files which often include financial and employment data.
