ResolverRAT, a previously undocumented remote access trojan (RAT), is being used in phishing attacks on global healthcare and pharmaceutical groups, according to cybersecurity firm Morphisec. The malware is distributed through region-specific phishing emails and uses in-memory execution, making it hard to detect. Morphisec also highlighted similarities between the phishing infrastructure used in this campaign and the earlier Rhadamanthys and Lumma efforts.
