Vodafone and Mercado Libre


The ransomware group that hit Samsung and Nvidia appears to have struck two new big-name targets in the tech sector: a South American e-commerce giant and a British telecom multinational.

Buenos Aires-based online marketplace MercadoLibre admitted in an SEC filing this week that source code and user data were accessed, although it did not reveal how.

“Although data from approximately 300,000 users (out of our nearly 140 million unique active users) was accessed, to date and according to our initial analysis, we have not found any evidence that our infrastructure systems have been compromised or that any users’ passwords, account balances, investments, financial information or credit card information were obtained. We are taking strict measures to prevent further incidents,” it said.

Separately, Vodafone is reportedly investigating claims that internal data was breached.

THE WHAT? Japanese beauty e-tailer Acro has been hit by a third-party data breach, which exposed more than 100,000 payment cards across two of its four beauty product websites. 

THE DETAILS The hack took place on the Three Cosmetics domain as well as Amplitude, with data exposed by consumers that purchased items between 21st May, 2020 and 18th August, 2021. 

Stolen data included cardholder names, payment card numbers, dates of expiry and security codes, according to The Daily Swig. 

The breach has been reported to law enforcement and Japan’s Personal Information Protection Commission, with affected customers having been notified by Acro from 24th February.

Monongalia Health

March 03, 2022 – West Virginia-based health system Monongalia Health began notifying patients of a healthcare data breach that resulted in unauthorized access to protected health information (PHI). Just a few months ago, Monongalia fell victim to a phishing attack that also exposed PHI.

Mon Health discovered the second data security incident on December 18, 2021, when it detected unusual network activity. After the discovery, Mon Health disabled a “significant portion” of its IT network and initiated downtime procedures.

The breach did not involve Mon Health’s EHR systems. Still, it potentially exposed the names, addresses, Medicare claim numbers, Social Security numbers, birth dates, health insurance plan member ID numbers, dates of service, patient account numbers, medical information, and health plan enrollment status of some patients, providers, employees, and contractors.


The screenshots ATW has posted on Twitter indicate that the group has accessed Rosatom’s Allure Reports.
