Cyber Security Headlines – Episode Summary Hosted by CISO Series | Release Date: June 23, 2025

In this episode of Cybersecurity Headlines, Steve Prentiss from the CISO Series delves into several significant cyber incidents impacting various industries globally. The episode covers attacks on major UK retailers, a security breach at Aflac, a severe cyberattack on Russian dairy producers, and more. Below is a detailed summary of the key discussions, insights, and conclusions presented in the episode.

1. UK Retailers Under Siege: Marks & Spencer and Co Op Attacks

[00:00] Steve Prentiss opens the episode by reporting on the coordinated cyberattacks targeting prominent British retailers, including Marks & Spencer and Co Op. The UK-based CY Monitoring Center (CMC) has classified these incidents as a single, combined cyber event due to the close timing and similar Techniques, Tactics, and Procedures (TTPs) employed by the attackers.

• Classification and Impact:

  • Category 2 Systemic Event: The CMC has designated the attacks as a Category 2 systemic event.
  • Financial Impact: The financial repercussions are estimated between $363 million and $592 million.
  • Similar Attack Vectors: Both attacks utilized social engineering tactics targeting IT help desks, indicating a coordinated effort by the threat actors.

• Harrods Attack:

  • While Harrods was also targeted, it has not yet been included in this assessment due to insufficient information. Further details are awaited to determine its linkage with the other attacks.

Notable Quote:

"We have labeled this a Category 2 systemic event with an anticipated financial impact of between $363 million and $592 million," — Steve Prentiss [00:00]

2. Aflac Investigates Suspicious Activity on U.S. Network

The report moves to Aflac, the largest provider of supplemental insurance in the United States, which has identified suspicious activity within its U.S. network.

• Scope of the Breach:

  • Data at Risk: Social Security numbers, claims information, customer health data, and Personally Identifiable Information (PII) of customers, beneficiaries, employees, and agents.

• Attribution and Response:

  • Cybercrime Campaign: The intrusion is attributed to an ongoing cybercrime campaign targeting the insurance sector.
  • Containment: The breach was detected and halted within hours, limiting potential damage.
  • Ongoing Investigation: A comprehensive review is underway to assess the full extent of the breach and implement further safeguards.

Notable Quote:

"The intrusion was stopped within hours," — Steve Prentiss [00:00]

3. Severe Cyberattack Disrupts Russian Dairy Industry

A critical cyberattack has struck Russia's dairy sector, affecting the Mercury platform, a component of the federal State Information System for veterinary surveillance and digital certification of animal-based products.

• Impact on Operations:

  • System Downtime: The Mercury platform was taken offline, marking the most severe attack compared to two previous incidents.
  • Shift to Manual Processes: Producers and suppliers are compelled to revert to paper-based veterinary certificates, disrupting digital workflows.

• Regulatory Implications:

  • Legal Requirements: Russian law mandates that businesses handling meat, dairy, eggs, and other animal products must register with Mercury and issue electronic veterinary documents.
  • Operational Barriers: Without electronic certification, processors cannot legally accept raw milk, jeopardizing product authenticity and safety verification.

Notable Quote:

"Without them, processors are legally barred from accepting raw milk as digital certification is required to verify product authenticity and safety," — Steve Prentiss [00:00]

4. Tonga's Ministry of Health Falls Victim to Ransomware Attack

The Ministry of Health in Tonga, a South Pacific island nation, has suffered a ransomware attack compromising its national Health Information System.

• Details of the Attack:

  • Discovery: The ransomware attack was detected on June 15.
  • Affected Systems: The breach impacts the system responsible for recording and registering hospital patients, including medical records, prescriptions, health risks, and future treatment plans.

• Response Efforts:

  • International Assistance: Cybersecurity experts from Australia arrived on June 20 to aid the Tongan government in mitigating the attack and restoring affected systems.

Notable Quote:

"This includes medical records, prescriptions, health risks and future plans for patients," — Steve Prentiss [00:00]

5. Microsoft Investigates OneDrive File Search Bug

Microsoft is currently investigating a bug affecting OneDrive users across various platforms, including Windows, Android, iOS, and web.

• Issue Description:

  • Search Functionality: Users are experiencing blank search results or no results at all when searching for files in specific upload locations.

• Current Status:

  • No Workaround: As of now, there is no known solution for affected users.
  • Timeline Uncertain: Microsoft has not provided an estimated timeframe for a fix, leaving users awaiting resolution.

Notable Quote:

"There is currently no known workaround for those affected and no estimated timeline for a fix," — Steve Prentiss [00:00]

6. Cloudflare Successfully Mitigates Record DDoS Attack

Cloudflare recently thwarted an unprecedented Distributed Denial-of-Service (DDoS) attack targeting a hosting provider.

• Attack Details:

  • Peak Traffic: The attack peaked at 7.3 terabits per second, surpassing the previous record by 12%.
  • Source Diversity: Over 122,000 source IP addresses from 161 countries launched the attack, with significant contributions from Brazil, Vietnam, Taiwan, China, Indonesia, and Ukraine.

• Mitigation Strategy:

  • Magic Transit: Cloudflare employed its network layer protection service, Magic Transit, to absorb and neutralize the attack without human intervention, maintaining service continuity for the hosting provider.

Notable Quote:

"Cloudflare mitigated this attack without human intervention using a network layer protection service called Magic Transit," — Steve Prentiss [00:00]

7. Kwai Lin Ransomware Enhances Pressure Tactics with 'Call Lawyer' Feature

The Kwai Lin Ransomware as a Service (RaaS) group has introduced a new feature aimed at increasing ransom payments through legal intimidation.

• New Feature Overview:

  • 'Call Lawyer' Button: Affiliates can now engage a lawyer during ransomware negotiations, leveraging legal pressure to coerce victims into paying larger ransoms.

• Strategic Advantage:

  • Legal Threats: By involving legal counsel, ransomware operators exploit victims' desire to avoid protracted legal battles, thereby increasing the likelihood of compliance and higher payments.

Notable Quote:

"This feature allows an affiliate ransomware group to bring a lawyer into negotiations with the victims, taking advantage of the fact that many companies wish to avoid legal proceedings and will therefore more readily comply," — Steve Prentiss [00:00]

8. German Table Napkin Manufacturer Fasana Files for Insolvency After Ransomware Attack

Fasana, a table napkin manufacturer based in Stottzheim, Germany, has declared insolvency following a debilitating ransomware attack.

• Incident Impact:

  • Financial Losses: Fasana incurred millions of euros in lost business and recovery costs, leading to its financial downfall.

• Current Status:

  • Recovery Efforts: Although production has resumed, the financial damage was irreversible.
  • Insolvency Proceedings: The company now has eight weeks to secure a buyer or face complete closure.

Notable Quote:

"Fasana... has filed for insolvency following a May 19 ransomware attack that left the company unable to print delivery notes, which subsequently paralyzed business operations," — Steve Prentiss [00:00]
