Threat Intelligence Reports
- Check Point Research warns of disinformation surrounding hacktivists’ multiple campaigns supporting both Russia and Ukraine: while there have been numerous attack claims, many of these “successes” remain either questionable or impossible to verify.
- Research shows 75% of the infusion pumps in healthcare organizations are vulnerable to known flaws.
- A new espionage tool, Daxin, has been used by China-affiliated threat actors in campaigns targeting governments, as well as telecom, transportation and manufacturing enterprises.
