Warning on KIMSUKY Cyber Actor's Recent Cyber Campaigns against Google's Browser and App Store Services

Another day, another ransomware gang. The Dark Power ransomware gang is new on the block, and is trying to make a name for itself. This blog dives into the specifics of the ransomware used by the gang, as well as some information regarding their victim naming and shaming website, filled with non-paying victims and stolen data.

Today, CISA released the Untitled Goose Tool to help network defenders detect potentially malicious activity in Microsoft Azure, Azure Active Directory (AAD), and Microsoft 365 (M365) environments. The Untitled Goose Tool offers novel authentication and data gathering methods for network defenders to use as they interrogate and analyze their Microsoft cloud services. The tool enables users to:

C’est une faille banale qui a exposé les relevés de cartes bancaires de milliers d’entreprises suisses pendant 18 mois. Et ni l’entreprise qui émet les cartes concernées, ni les banques qui les fournissent à leurs clients ne comptent diffuser l’information.
Motif? Le problème a été réglé et les recherches n’ont pas permis d’observer un accès indu aux informations. Une stratégie de communication qui interpelle, à l’heure où la sécurité des données devient un enjeu majeur pour les entreprises.

There are at least two kinds of catastrophe scenarios, and both are getting more plausible

The number of victims affected by a mass-ransomware attack, caused by a bug in a popular data transfer tool used by businesses around the world, continues to grow as another organization tells TechCrunch that it was also hacked.

The City of Toronto told TechCrunch in a revised statement on March 23: “Today, the City of Toronto has confirmed that unauthorized access to City data did occur through a third party vendor. The access is limited to files that were unable to be processed through the third party secure file transfer system.”

• Emotet resumed spamming operations on March 7, 2023, after a months-long hiatus.
• Initially leveraging heavily padded Microsoft Word documents to attempt to evade sandbox analysis and endpoint protection, the botnets switched to distributing malicious OneNote documents on March 16.
• Since returning, Emotet has leveraged several distinct infection chains, indicating that they are modifying their approach based on their perceived success in infecting new systems.
• The initial emails delivered to victims are consistent with what has been observed from Emotet over the past several years.

Large Language Models (LLM) have made amazing progress in recent years. Most recently, they have demonstrated to answer natural language questions at a surprising performance level. In addition, by clever prompting, these models can change their behavior. In this way, these models blur the line between data and instruction. From "traditional" cybersecurity, we know that this is a problem. The importance of security boundaries between trusted and untrusted inputs for LLMs was underestimated. We show that Prompt Injection is a serious security threat that needs to be addressed as models are deployed to new use-cases and interface with more systems.

• Mandiant tracked 55 zero-day vulnerabilities that we judge were exploited in 2022. Although this count is lower than the record-breaking 81 zero-days exploited in 2021, it still represents almost triple the number from 2020.
• Chinese state-sponsored cyber espionage groups exploited more zero-days than other cyber espionage actors in 2022, which is consistent with previous years.
• We identified four zero-day vulnerabilities exploited by financially motivated threat actors. 75% of these instances appear to be linked to ransomware operations.
• Products from Microsoft, Google, and Apple made up the majority of zero-day vulnerabilities in 2022, consistent with previous years. The most exploited product types were operating systems (OS) (19), followed by browsers (11), security, IT, and network management products (10), and mobile OS (6).
