Ongoing malware distribution campaigns are using ISO disk images to deliver AsyncRAT, LimeRAT and other commodity malware to victims. The infections leverage process injection to evade detection by endpoint security software. These campaigns appear to be linked to a new version of the 3LOSH crypter, previously covered here.…For the Lazarus threat actor, financial gain is one of the prime motivations, with a particular emphasis on the cryptocurrency business. As the price of cryptocurrency surges, and the popularity of non-fungible token (NFT) and decentralized finance (DeFi) businesses continues to swell, the Lazarus group’s targeting of the financial industry keeps evolving.…

Geopolitical tensions often make headlines and present a golden opportunity for threat actors to exploit the situation, especially those targeting high-profile victims. In the past month while the Russian invasion of Ukraine was unfolding, Check Point Research (CPR) has observed advanced persistent threat (APT) groups around the world launching new campaigns, or quickly adapting ongoing ones to target victims with spear-phishing emails using the war as a lure.…
Spearphishing crafted with industry-specific terms derived from intelligence gathering techniques to trick a recipient into opening a file is especially difficult to identify. This is especially true when an adversary has knowledge of how a business works and the processes that underpin it. Using this knowledge, a lure can be crafted that takes advantage of these day-to-day processes – for example, settling the cost of a fuel transaction.…
