Cybersecurity in the Last Final Week of May 2025: Major Incidents and Protection Strategies

As May 2025 is about to be concluded, the cybersecurity landscape witnessed a series of significant breaches affecting various sectors, from government and healthcare institutions to retail giants. These incidents underscore the escalating sophistication of cyber threats and the imperative for robust cybersecurity measures.

In a concerning development, cybercriminals employed artificial intelligence to impersonate Susie Wiles, the White House Chief of Staff. The perpetrators accessed her personal contacts and dispatched messages requesting sensitive information, including lists of potential pardon recipients and cash transfers. The FBI is investigating the breach, which, while not attributed to foreign actors, highlights vulnerabilities in personal communication channels.

🛍️ Retail Sector Breaches: Victoria’s Secret and Marks & Spencer

Victoria’s Secret: The U.S. website of the lingerie retailer was taken offline due to a "security incident," disrupting order fulfillment and customer service. While the nature of the breach remains undisclosed, internal operations, including employee email access, were affected .

Marks & Spencer (UK): The retailer suffered a cyberattack attributed to the hacker group Scattered Spider, leading to disruptions in online sales and contactless payments. The breach, linked to third-party human error, exposed customer data and may result in significant financial losses.

Adidas (Germany): Sportswear giant Adidas also disclosed a cyber incident this week after hackers accessed a “third-party customer service provider” and stole the contact information of customers who contacted the help desk in the past. The company has also notified the relevant authorities regarding this security incident and will alert those affected by the data breach.

☁️ Commvault Metallic Cloud Platform Breach

Commvault's cloud-based data protection platform, Metallic, experienced a cyberattack exploiting a zero-day vulnerability (CVE-2025-3928) in its Web Server. This breach potentially compromised Microsoft 365 environments of its clients by allowing unauthorized access via exposed client secrets. The Cybersecurity and Infrastructure Security Agency (CISA) has added the flaw to its Known Exploited Vulnerabilities catalog and mandated federal agencies to apply patches within three weeks.

🔐 Massive Password Leak Exposes Millions

A cybersecurity researcher discovered an unprotected database containing over 184 million unique passwords linked to services like Google, Apple, Microsoft, and Facebook. The data, likely harvested via infostealer malware, also included sensitive information from bank accounts, health services, and government portals. The database has since been taken offline, but the owner remains unidentified.

🏥 Healthcare Sector Under Siege: Kettering Health Hospital (OHIO)

In a notice Kettering Health officials posted online this week, it states its network of hospitals are under a cyberattack. It said the attacks forced hospitals to cancel appointments. Patients took to social media concerned their personal information was leaked. University of Cincinnati Information & Technology Associate Professor Jacques Bou has been following the case. He said health care networks are especially vulnerable to cyber attacks in part because of all the places information is stored. Kettering Health did not say what information is at risk in that statement, but did say they had procedures to correct the problem. As a patient, Bou Abdo said there’s a little you can do outside of what hospitals are already doing, except to try not to get scammed again. Kettering Health has also been the target of a phone scam trying to get patients to pay money. They’ve confirmed that’s not them.
