WhatsApp has introduced an extra layer of privacy called Advanced Chat Privacy, that allows users to block participants from sharing the contents of a conversation in both traditional chats and chat groups.

“This new setting available in both chats and groups helps prevent others from taking content outside of WhatsApp for when you may want extra privacy,” WhatsApp said in a statement.

When this optional feature is enabled, it prevents other chat participants from exporting chats, auto-downloading media to their phone, and using messages for AI features. It’s worth noting that users can still take individual screenshots, or manually download the media.

​The new Advanced Chat Privacy feature is part of a broader effort to make communicating using WhatsApp more secure.

Car rental giant Hertz has announced and begun notifying its customers of a data breach that included their personal information and driver’s licenses. The data breach affected at least 100,000 customers.

The rental company, which also owns the Dollar and Thrifty brands, said in notices on its website that the breach relates to a cyberattack on one of its vendors, Cleo, providing file transfer platform used by Hertz.

“On February 10, 2025, we confirmed that Hertz data was acquired by an unauthorized third party that we understand exploited zero-day vulnerabilities within Cleo’s platform in October 2024 and December 2024.”

The stolen data varies by individual and region, but includes customer names, contact information, date of birth, credit card information, driver’s license information and information related to workers’ compensation claims. Hertz said a smaller number of customers had their Social Security or other government identification numbers, passport information, Medicare or Medicaid ID, or injury-related information associated with vehicle accident claims, were impacted by the event.

Hertz has disclosed the breach with several US states, including California, Maine, and Texas. Hertz said at least 3,400 customers in Maine were affected, and some 96,665 customers in Texas, but neither listed the total number of affected individuals.

Pennsylvania’s largest Workers and Teachers’ Union, PSEA, has exposed the personal information of over half a million individuals. PSEA is a labor union that represents public school teachers, higher education faculty members, school support staff, and retired educators across the Keystone State.

“PSEA experienced a security incident on or about July 6, 2024 that impacted our network environment,” the organization said in breach notification letters sent on March 17, 2025 to 517,487 individuals. “Through a thorough investigation and extensive review of impacted data which was completed on February 18, 2025, we determined that the data acquired by the unauthorized actor contained some personal information belonging to individuals whose information was contained within certain files within our network.”

PSEA says the stolen information varies by individual and consists of personal, financial, and health data, including driver’s license or state IDs, social security numbers, account numbers and PINs, account usernames and passwords, security codes, payment card information, passport information, taxpayer ID numbers, health insurance and medical information.

While the workers and teachers’ union has not disclosed the threat actor’s identity, the Rhysida ransomware took credit for the PSEA data breach in September 2024 and listed the labor union on its data leak site.

A law firm is currently investigating whether affected individuals are entitled to compensation.

On March 9, 2025, threat intelligence firm GreyNoise observed a coordinated surge in SSRF exploitation, affecting multiple widely used platforms. At least 400 IP addresses have been seen actively exploiting multiple SSRF CVEs simultaneously, with notable overlap between attack attempts. The top countries receiving SSRF exploitation attempts during the surge were the US, Germany, Singapore, India, and Japan. GreyNoise has observed Grafana path traversal attempts preceding the coordinated SSRF surge, indicating attackers may be using Grafana as a foothold for deeper exploitation.

Server-Side Request Forgery (SSRF) is a web security vulnerability that allows an attacker to cause the server-side application to make requests to an unintended location, either internally towards the organization’s network or externally to exfiltrate data. It is one of the OWASP Top 10 Application Security Risks.

Historical parallels: SSRF vulnerabilities played a key role in the 2019 Capital One breach, which exposed 100M+ records.

GreyNoise has identified active exploitation attempts against the following flaws:

• CVE-2017-0929 (CVSS score: 7.5) – DotNetNuke
• CVE-2020-7796 (CVSS score: 9.8) – Zimbra Collaboration Suite
• CVE-2021-21973 (CVSS score: 5.3) – VMware vCenter
• CVE-2021-22054 (CVSS score: 7.5) – VMware Workspace ONE UEM
• CVE-2021-22175 (CVSS score: 9.8) – GitLab CE/EE
• CVE-2021-22214 (CVSS score: 8.6) – GitLab CE/EE
• CVE-2021-39935 (CVSS score: 7.5) – GitLab CE/EE
• CVE-2023-5830 (CVSS score: 9.8) – ColumbiaSoft DocumentLocator
• CVE-2024-6587 (CVSS score: 7.5) – BerriAI LiteLLM
• CVE-2024-21893 (CVSS score: 8.2) – Ivanti Connect Secure
• OpenBMCS 2.4 Authenticated SSRF Attempt (No CVE)
• Zimbra Collaboration Suite SSRF Attempt (No CVE)

Organizations should promptly patch and secure affected systems, apply mitigations for targeted CVEs, and restrict outbound access to necessary endpoints. They should also monitor for suspicious outbound requests by setting up alerts for any unexpected activity.

Meta has fired “roughly” 20 employees for leaking confidential information, The Verge reports.

“We tell employees when they join the company, and we offer periodic reminders, that it is against our policies to leak internal information, no matter the intent,” Meta spokesperson Dave Arnold told the publication. “We recently conducted an investigation that resulted in roughly 20 employees being terminated for sharing confidential information outside the company, and we expect there will be more. We take this seriously, and will continue to take action when we identify leaks.”

The move comes in response to a surge of news stories that shared leaked details about Meta’s internal meetings and undisclosed product plans, including a recent all-hands led by Meta CEO Mark Zuckerberg. Following the leaks, Meta warned employees that leakers would be fired.

Meta did non disclose any details about the content leaked.

Hipshipper, an international shipping platform used by sellers on eBay, Shopify and Amazon, accidentally exposed 14.3 million shipping labels with personal customer information. Researchers at Cybernews found the exposed data in December 2024, but it wasn’t fixed until January 2025. Hipshipper helps people ship packages to over 150 countries, offering tracking, free insurance and easy returns. The unprotected AWS bucket exposed shipping labels are important because they detail what’s inside the packages and where they’re supposed to go.

Cybernews researchers added: “Cybercriminals can exploit leaked data to orchestrate advanced scams and phishing attacks. For example, crooks may impersonate trusted businesses and distribute fraudulent messages that leverage specific order details to demand urgent verification of personal or financial information.” Sophisticated attackers could employ the details to impersonate businesses and lure sensitive information from customers. With shipping labels at hand, attackers could reference specific orders, adding credibility to otherwise fraudulent demands.

The leaked data included full names, home addresses, phone numbers and order details (dates of mailing, parcel information, etc.).

Online food ordering and delivery platform GrubHub suffered a data breach that exposed the personal information of drivers, merchants and customers.

“We recently detected unusual activity within our environment traced to a third-party service provider for our Support Team” the company said on Monday, February 3, 2025.

“We immediately terminated the account’s access and removed the service provider from our systems altogether.”

The following data was accessed, varying by individual: Names, email addresses and phone numbers, as well as partial payment card information for a subset of campus diners (card type and last four digits of the card number).

The threat actor also accessed hashed passwords for certain legacy systems, and the company rotated any passwords that was believed might have been at risk.

GrubHub has not disclosed whether it was targeted by a ransomware attack, and as of this writing, no known ransomware group has claimed responsibility.

Grubhub is a popular food-ordering and delivery platform with more than 375,000 merchants and 200,000 delivery providers using its platform in more than 4,000 US cities.

DeepSeek, the Chinese AI startup known for its DeepSeek-R1 LLM model, has publicly exposed two databases containing sensitive user and operational information.

Wiz Research discovered a publicly accessible ClickHouse database belonging to DeepSeek, containing over 1 million log entries, and exposing chat history, secret keys, and backend details.

“Within minutes, we found a publicly accessible ClickHouse database linked to DeepSeek, completely open and unauthenticated, exposing sensitive data. It was hosted at oauth2callback.deepseek.com:9000 and dev.deepseek.com:9000.” reads the report published by Wiz.

“This database contained a significant volume of chat history, backend data and sensitive information, including log streams, API Secrets, and operational details.” continues the report.

This exposure could have allowed full database control and potential privilege escalation within the DeepSeek environment, without any authentication.

After responsible disclosure, DeepSeek promptly secured the issue.

In February 2024, UnitedHealth subsidiary Change Healthcare suffered a massive ransomware attack, leading to widespread disruption to the US healthcare system. This disruption prevented doctors and pharmacies from filing claims and pharmacies from accepting discount prescription cards, causing patients to pay full price for medications.

It was later discovered that the BlackCat ransomware gang, also known as ALPHV, was behind the attack. The threat actors used stolen credentials to breach the company’s Citrix remote access service, which did not have multi-factor authentication enabled. After breaching the network, the threat actors stole 6 TB of data and encrypted computers, causing the company to shut down IT systems and its online platforms for billing, claims, and prescription fulfillment.

In October 2024, UnitedHealth reported to the US Department of Health and Human Services Office for Civil Rights that the attack affected 100 million people. However, on January 24, 2025, UnitedHealth confirmed that the figure has nearly doubled to 190 million, which is 56% of the US population.

The Securities and Exchange Commission (SEC) Cybersecurity Disclosure rules require that public companies disclose material cybersecurity incidents within four business days of becoming alerted to them.

Despite these rules, companies have managed to take extensive time in investigating and addressing critical aspects of their breaches. In fact, it took Change Healthcare four months to notify customers of its incident, nine months to admit that 100 million people were affected, and nearly a year to update that figure to 190 million.
