Timeshare scams in Mexico, the DoppelPaymer ransomware gang is arrested, and a major data breach rocks Oakland, California. Here are the latest threats and advisories for the week of March 10, 2023.

Alerts and warnings of threats

The US Federal Bureau of Investigation (FBI) has issued an advisory regarding timeshare scams in Mexico, which affected more than 600 people and resulted in victim losses of approximately $39.6 million last year. How does the scam work? Timeshare owners in Mexico receive an unexpected email or phone call from scammers asking to sell or rent their timeshare. When owners agree to sell, they pay an upfront fee to cover alleged closing costs, advertising fees, and similar expenses. Not surprisingly, this is usually the last time victims hear from the scammers. Owners can protect themselves by treating unexpected phone or email inquiries about their timeshare with caution and by researching the timeshare resale companies they are considering.

Twitter’s recent removal of two-step SMS verification for non-Twitter Blue subscribers may leave some users wondering how to protect their accounts.

For example, by using an authenticator app, backup code, or security key.

The February 8 ransomware attack in the city of Oakland, California escalated and the perpetrators are now leaking sensitive data. The Play ransomware group is behind the attack and began leaking data last week, consisting of a 10 GB multipart RAR file reportedly containing employee information, confidential documents, passports, and other private information. .

As America’s critical infrastructure faces an increasing number of cyberattacks, the Environmental Protection Agency (EPA) released requirements for public water systems (PWS). in English) to safeguard drinking water supplies.

The program is part of the Biden administration’s ICS Cybersecurity Initiative to protect critical infrastructure.
