🗓️ What’s New

Microsoft Faces Criticism Over Loss of Security Log Data
Microsoft is under fire for its decision to stop storing detailed security log data for free, impacting organizations' ability to track potential breaches and detect threats. The move is seen as a blow to cybersecurity visibility, as companies will now need to pay for more comprehensive logging features. Experts argue that the decision may increase the risk of undetected breaches and weaken security defenses. Read more (3 Mins)

New macOS Gatekeeper Bypass Discovered
Palo Alto Networks' Unit 42 team has uncovered a new Gatekeeper bypass vulnerability in macOS that allows attackers to execute unauthorized code on victim machines. This bypass exploits weaknesses in the security feature meant to prevent unverified software from running, putting macOS users at risk of malware infections. Apple has been notified of the issue, and users are encouraged to stay vigilant and update their systems as patches become available. Read more (7 Mins)

EU Cybersecurity Bill (NIS2) Hits Compliance Deadline
The EU’s updated Network and Information Systems (NIS2) directive has reached its compliance deadline, mandating stricter cybersecurity measures for critical infrastructure and digital service providers. The bill requires organizations to enhance their security protocols, incident reporting, and risk management practices. Companies failing to comply may face substantial fines. NIS2 aims to boost cyber resilience across the European Union, particularly in sectors like energy, healthcare, and finance. Read more (4 Mins)

Hackers Exploit Roundcube Webmail XSS Vulnerability
A critical cross-site scripting (XSS) vulnerability has been discovered in the popular Roundcube Webmail platform. This flaw allows attackers to inject malicious scripts, which could lead to the theft of sensitive data, including login credentials and session tokens. Roundcube has released security updates to address this issue, and users are urged to apply patches immediately to prevent potential exploitation. Read more (3 Mins)

Hackers Exploit Genuine Code-Signing Certificates for Malware Distribution
Cybercriminals are increasingly abusing legitimate code-signing certificates to distribute malware. By using trusted certificates, attackers can bypass security defenses and trick users into downloading malicious software. This tactic allows malware to appear more credible and less likely to trigger security alerts. The rise in these abuses highlights the need for organizations to carefully monitor their certificate use and strengthen their defenses against certificate-based attacks. Read more (7 Mins)

Ransomware Attacks on Microsoft Customers Triple
Microsoft reports a threefold increase in ransomware attacks on its customers. The rise in attacks is attributed to evolving ransomware tactics, targeting vulnerabilities in cloud services and exploiting human error. Microsoft emphasizes the importance of multi-factor authentication (MFA), security updates, and proactive threat monitoring to mitigate the risks associated with these escalating threats.
