Microsoft has warned users that its patches for the dangerous Meltdown CPU bug won't reach them if their third-party antivirus hasn't been updated to support this week's Windows security update.

By now Windows users should have received the patches Microsoft released yesterday to plug the widespread Meltdown bug and its companion Spectre, which expose most computers and phones to speculative execution side-channel attacks that affect chips from Intel, AMD, and Arm.

Microsoft released software updates for Internet Explorer, Microsoft Edge, Windows, and SQL Server, but customers will also need to apply firmware updates from their respective hardware vendors too.

Surface and Surface Book users can expect an automatic firmware update from Microsoft but those with other hardware will need to check with their vendors.

Sicherheitsexperten von Proofpoint untersuchten das Mining-Botnet Smominru, das auf mehr als 500.000 Windows-Maschinen die Kryptowährung Minero schürft.

Nach Erkenntnissen von Sicherheitsexperten der Firma Proofpoint missbrauchen Kriminelle die Rechenleistung von mehr als einer halben Million Windows-Systemen, um die Kryptowährung Minero zu "schürfen". Laut Proofpoint handelt es sich bei den befallenen Maschinen vor allem um Windows-Server, von denen viele in Russland, Indien, Taiwan und der Ukraine laufen. Im Beobachtungszeitraum von Mai 2017 bis Januar 2018 hätten die Angreifer Mineros im Wert von rund 3,6 Millionen US-Dollar ergattert.

Server unbrauchbar
Auf den Stromkosten bleiben die Geschädigten sitzen, außerdem vermuten die Sicherheitsforscher, dass viele der befallenen Server wegen der zusätzlichen Rechenlast nur noch eingeschränkt funktionieren.
