CISA removes fake CVE from KEV catalog

CISA has removed CVE-2022-28958 from its Known Exploited Vulnerabilities (KEV) catalog. The flaw, which was initially described as an actively exploited D-Link router vulnerability, turned out to be a fake vulnerability. This is not the first time CISA has removed a CVE from its catalog. 

New Linux RAT Krasue targets Thailand

Group-IB has conducted an analysis of Krasue, a new Linux RAT that has been used in attacks against organizations in Thailand. The malware has been around since at least 2021, but it has managed to stay under the radar. Krasue, which contains several embedded rootkits, is believed to be deployed as part of a botnet or sold by initial access brokers. 

An entire country’s DNS name resolution hijacked

SEC Consult researchers have demonstrated the threat posed by DNS attacks by hijacking the DNS name resolution of an entire country by exploiting a DNS cache poisoning vulnerability. A malicious attack could have caused “serious harm”, the company said. 

Fake Lockdown Mode

Jamf has discovered a post-exploitation tampering technique that can allow malware to trick users into believing that their iPhone is running in Lockdown Mode (a feature designed to protect users against highly sophisticated attacks) when in reality the victim does not benefit from the feature’s protection. The company pointed out that the attack method does not exploit any actual vulnerability in iOS or Lockdown Mode. 

MLflow vulnerability exposes ML models and training data

Contrast Security has found a vulnerability in MLflow, a development framework for machine learning (ML) lifecycle management, that could lead to the exposure of an ML model and all training data to an attacker. Databricks, the creator and maintainer of MLflow, has been working on a patch.

Using AI to jailbreak LLMs

Robus Intelligence has found a way to use AI to automatically jailbreak GPT-4 and other large language models (LLMs). The attack method, named Tree of Attacks with Pruning (TAP), can be used “to induce sophisticated models like GPT-4 and Llama-2 to produce hundreds of toxic, harmful, and otherwise unsafe responses to a user query (e.g. ‘how to build a bomb’) in mere minutes”.

40% of Google Drive files contain sensitive information

A report from data security firm Metomic shows that over 40% of files stored in Google Drive contain sensitive information. The result is based on a scan of roughly 6.5 million files. Approximately 18,000 files contained highly sensitive data such as personally identifiable information.
