Weekly Industry View

Industry View
Industry Information
Banking & Finance East Security researchers observed a new campaign carried out by the North Korea-linked actor Thallium. The group is known to particularly focus on individuals working on North Korean issues. Thallium is using phishing emails disguised as financial transaction notifications and impersonating domestic commercial banks in South Korea. The emails feature designs similar to legitimate notifications. They contain an Excel attachment, which tricks the user into enabling malicious macro code. The attack may result in a data breach, and might spread through the victim’s network.
Government United States law enforcement discovered a step-by-step tutorial on how to commit unemployment identity fraud through the Texas Workforce Commission website. The guide was posted in a WhatsApp group chat of the Nigerian cybercriminal organisation known as Scattered Canary. The group uses stolen identities obtained from the dark web to file benefit claims. Scattered Canary uses prepaid Green Dot cards to funnel the money offshore before the claims are flagged.
Technology Jamf Protect researchers discovered an Apple macOS vulnerability exploited by XCSSET malware. The zero-day flaw, tracked as CVE-2021-30713, bypassed the Transparency Consent and Control framework, and allowed the attackers to gain full disk access, screen recording abilities, and other permissions without the user’s explicit consent. XCSSET operators exploited the issue to take screenshots of the victim’s desktop. To exploit the newly discovered flaw, the malware injects a custom AppleScript into a donor application with pre-existing screen recording permissions, such as Zoom. The issue was patched in macOS versions 11.4 and above.
Healthcare Cyble researchers observed COVID-19 vaccination registration scams targeting Indian users. The scammers call potential victims impersonating officials from legitimate organisations asking for their names, dates of birth, Aadhar card, and other details to purportedly register them for the vaccine. The victims are then tricked into providing one-time passwords associated with their Aadhar numbers. The fraudsters might then use the submitted details to make unauthorised financial transactions.
Cryptocurrency Sentinel Labs researchers identified an ongoing cryptocurrency mining campaign targeting Docker Linux systems with XMRig. The malware relies on several obfuscation methods, rather than specific exploit components. The attacks involve multiple shell scripts, one of which reuses multiple patterns of base64 encoding which the researchers take as evidence that the threat actor is inexperienced. The attacker uses steganography to bypass detection and download a JPEG file containing an ELF binary.
