Russian cybersecurity firm, Kaspersky Lab, has told workers in its U.S.-based division that they are being laid off this week and that it is closing its U.S. business, according to several sources. The sudden move comes after the U.S. Commerce Department announced last month that it was banning the sale of Kaspersky software in the U.S. beginning July 20. The company has been selling its software here since 2005.
For more than six years, the Global Research and Analysis Team (GReAT) at Kaspersky has been publishing quarterly summaries of advanced persistent threat (APT) activity.

They are designed to highlight the significant events and findings that we feel people should be aware of.
Hi all, Today we have very big and important news. Kaspersky experts have discovered an extremely complex, professionally targeted cyberattack that uses Apple’s mobile devices.

in February 2023, Kaspersky technologies detected a number of attempts to execute similar elevation-of-privilege exploits on Microsoft Windows servers belonging to small and medium-sized businesses in the Middle East, in North America, and previously in Asia regions. These exploits were very similar to already known Common Log File System (CLFS) driver exploits that we analyzed previously, but we decided to double check and it was worth it – one of the exploits turned out to be a zero-day, supporting different versions and builds of Windows, including Windows 11. The exploit was highly obfuscated with more than 80% of the its code being “junk” elegantly compiled into the binary, but we quickly fully reverse-engineered it and reported our findings to Microsoft. Microsoft assigned CVE-2023-28252 to the Common Log File System elevation-of-privilege vulnerability, and a patch was released on April 11, 2023, as part of April Patch Tuesday.
Les tensions internationales actuelles causées par l’invasion de l’Ukraine par la Russie s’accompagnent d’effets dans le cyberespace. Si les combats en Ukraine sont principalement conventionnels, l’ANSSI constate l’usage de cyberattaques dans le cadre du conflit. Dans un espace numérique sans frontières, ces cyberattaques peuvent affecter des entités françaises et il convient sans céder à la panique de l’anticiper et de s’y préparer. Aussi, afin de réduire au maximum la probabilité de tels événements et d’en limiter les effets, l’ANSSI partage des bonnes pratiques de sécurité ainsi que des éléments sur la menace et invite l’ensemble des acteurs à s’en saisir. A cette fin, ce bulletin centralise et diffuse les éléments d’intérêt cyber en lien avec le contexte actuel pour favoriser le renforcement du niveau de protection de l’ensemble des entités françaises. Il sera mis à jour régulièrement.
