Attack Type mentions in Cryptocurrency

This chart shows the trending attack types related to Cryptocurrency within a curated list of cyber sources over the past week.

Weekly Industry View

Industry Information
Volexity researchers observed renewed activity by North Korean threat actor Lazarus Group, with the latest campaign likely targeting cryptocurrency users and organisations with AppleJeus malware. Lazarus Group was seen using new techniques, including a new variation of DLL sideloading not previously seen before. AppleJeus is spread via a website called BloxHolder, which is largely a clone of the HaasOnline automated cryptocurrency trading platform. The site contains an MSI file for the QTBitcoinTrader app that is bundled with the malware.
Jcrambler researchers discovered threat actors using new techniques in web skimming attacks that involve gaining control of defunct domains that formerly hosted popular JavaScript libraries. Campaigns from three threat actors were observed, one of which targeted the Cockpit JavaScript library, which is end-of-service, acquiring the domain name and using it to serve a skimming script via the same URL. The other two campaigns targeted the e-commerce websites directly, injecting malicious scripts into their homepages, one of which was disguised as Google Tag Manager, using string concatenation to avoid detection.
Critical Infrastructure
Cyble researchers discovered a new ransomware operation, called BlackMagic, that appears to originate from Iran. The group uses double extortion to target victims, and has disclosed details of over ten victims in the transportation and logistics industry to date, all of which are from Israel. The group is suspected to be politically motivated. The ransomware payload is a 64-bit DLL file that is dropped on the victim system and executed using rundll32. The group’s ransom note does not provide contact details or cryptocurrency addresses for ransom payment, but instead contains links to social media channels used for advertising the victim’s data. 
CrowdStrike discovered an intrusion campaign targeting telecommunications and business outsourcing companies. The attackers attempt to gain access to mobile carrier networks and conduct SIM swapping attacks. The campaign has been ongoing since June 2022. Social engineering techniques are used to impersonate IT personnel and convince victims to visit a credential harvesting site or run commercial remote monitoring and management tools used for persistence. Other tactics involve the use of compromised credentials to access an organisation’s Azure tenant, or the exploitation of CVE-2021-35464 in the ForgeRock OpenAM application server. The attacks appear to be financially motivated, with the campaign attributed to threat actor SCATTERED SPIDER with low confidence.
Banking & FInance
K7 Security researchers identified a sample of the Zanubis banking trojan that disguises itself as the mobile application of Peru’s tax authority, SUNAT. The app asks for accessibility service and battery optimisation permissions to gather data from the victim’s device. It uses an overlay screen over the targeted application to acquire login credentials for a number of banks.
