Last Friday, Prudential Financial began informing over 36,000 people of a data incident that occurred in early February 2024.
The breach, first disclosed in a regulatory filing with the SEC in February, occurred on February 4 and was purportedly discovered the next day.
Prudential reported at the time that the attackers had gained access to systems including business administrative and user data, as well as employee and contractor accounts.
A week later, the ransomware gang Alphv/BlackCat claimed credit for the attack and added Prudential to their Tor-based leak site. This organisation was also responsible for a large outage in the US health system last month, hitting Change Healthcare systems and services.
As per a March 29 complaint with the Maine Attorney General's Office, Prudential has verified that the hackers have gained access to the personal data of 36,545 people.
We discovered through the investigation that on February 4, 2024, an unauthorised third party gained access to our network and removed a small percentage of personal information from our systems, the report reads.
“Companies are always likely to remain wary of really rapid disclosure, given the financial impact these things can have on them, and use all the ‘tricks’ they can to delay,” commented Nick France, chief technology officer at Sectigo.
“Ultimately, I believe that the new SEC regulations should make these processes work faster; however, given the wording of the regulation and the fact that it only came into effect at the very end of 2023, it may take some time before we see disclosures happening at the 4-day pace.”
Individuals impacted by the Prudential breach are being notified of the issue by written notice. Names and other personal identifiers, as well as driver's licence numbers or non-driver identity card numbers, were among the compromised data.
