Cyber Round-up for 17th May

Welcome to Ironshare’s Cyber Round-up, where we look back at the events of that last week to cover some of the news, posts, views, and highlights from the world of Security.

Security News

Google Patches Third Actively Exploited Chrome Zero-Day in One Week

Google has released an emergency security update for Chrome to fix CVE-2024-4947, the third zero-day vulnerability exploited within a week. This high-severity flaw, caused by a type confusion in the V8 JavaScript engine, was reported by Kaspersky researchers and can lead to arbitrary code execution. This update follows the recent patches for CVE-2024-4671 and CVE-2024-4761, highlighting ongoing security challenges for Chrome. The update is available now for all users on Mac, Windows, and Linux; Microsoft is also working on a fix for Edge.  


Cybercriminals Exploit Fake DocuSign Templates to Steal Credentials

Cybercriminals are increasingly using fake DocuSign templates to carry out phishing attacks, targeting organizations to steal credentials and sensitive data. These scams exploit the familiarity and trust users have with DocuSign, an electronic signature service, by sending emails that appear to be legitimate DocuSign notifications. The emails often contain links to malicious websites designed to steal login credentials.

To protect against these scams, users should be cautious of unexpected DocuSign emails, verify the sender's email address, and avoid clicking on links directly from emails. Instead, they should access documents by logging into DocuSign's official website. Organizations should also invest in comprehensive security awareness training to educate their users, specifically on the threat of email phishing attacks.


Dell Data Breach Exposes Information of 49 Million Customers

Dell has reported a data breach affecting approximately 49 million customers. The breach involved the unauthorized access of customer names, physical addresses, and Dell order information, including details about purchased hardware, service tags, item descriptions, and warranty information. Notably, financial details, email addresses, and phone numbers were not compromised.

The breach was discovered after a threat actor attempted to sell the stolen data on a hacking forum and while Dell claims that the breach does not pose significant risks due to the nature of the data involved, cybersecurity experts warn that the exposed information could still be used for targeted attacks, such as phishing.

Dell is currently working with law enforcement and a third-party forensics firm to investigate the incident and has advised affected customers to be cautious of any suspicious communications that appear to be from Dell, particularly those requesting software installations or password changes.
