Today, the UK and partners have exposed Russian state-supported actors LAUNDRY BEAR for a phishing campaign targeting Western organisations. Act now to mitigate the threat⬇️ www.ncsc.gov.uk/news/uk-and-partner…
Quote from NCSC Chief Operating Officer, Beth Hopkins CMG, which reads: "This phishing campaign demonstrates how hostile actors will ruthlessly adapt techniques and exploit vulnerable technology in pursuit of their aims to steal sensitive information from Western organisations. We will continue to call out malicious cyber activity supported by the Russian state and urge everyone to follow NCSC guidance to raise resilience, including steps to strengthen online account security".
