Google Chrome is impacted by another zero-day vulnerability that is being exploited. The vulnerability is tracked as CVE-2023-3079 and is related to a type of confusion bug in the V8 JavaScript engine. This vulnerability impacts Chrome versions prior to 114.0.5735.110.
Exploitation can occur by persuading a user to visit a crafted HTML page. Google does not release technical details of the attack impact, but exploitation can lead to code execution or a compromise of the user’s browser, which could lead to other, more severe attacks.
Users should upgrade to version 114.0.5735.110 for Windows and 114.0.5735.106 for macOS and Linux. It is also recommended that endpoints be protected and monitored with an Endpoint Detection & Response platform to efficiently respond to anomalous activity.
For a complimentary consultation, fill out the form below and we will be in touch soon.
On June 6, 2023, the Adlumin Threat Research group wrote about discovering a novel malicious PowerShell script targeting the aerospace industry. The script is considered unique because it evaded Endpoint Detection and Response (EDR) software with novel use of encryption and WMI. PowerDrop included a Remote Access Trojan (RAT).
Potential Impact
An attacker-controlled remote access mechanism is one of the early steps in full network compromise, leading to ransomware or data exfiltration.
Ensure that your organization is not relying on “set and forget” security software. Network security requires continual vigilance and threat hunting. While PowerDrop might have evaded EDR detection, subsequent attacker actions can be detected.

Several sources online reported this past weekend, users of “Atomic Wallet,” a cryptocurrency wallet known for its versatility, lost more than $35 million in what may be exploitation by the North Korean Lazarus group. Many impacted users report having keys saved offline and having never shared them. Stolen funds have been tracked to a cryptocurrency mixer known to be used by the Lazarus group.
For impacted Atomic Wallet users, the impact is a devastating loss of cryptocurrency.
If you store cryptocurrency, ensure that you’re following all possible security recommendations. The cryptocurrency industry and any associated government regulations are in their infancy, so understand that the theft risk is significant.
