Oracle Property Management Flaw Posing Risk to Hospitality Industry

The hospitality industry has suffered a hit from the recent flaws found in the Oracle Hospitality Opera 5 Property Services software. Oracle have assigned a CVSS score of 7.2 and a moderate severity rating which state that exploitation requires an authenticated attacker with highly elevated privileges, however researchers have disputed this and labelled it as an “incorrect assessment” of this vulnerability. The CTO of Assetnote responded to Oracle’s assessment stating that “this vulnerability does not require any authentication to exploit, despite what Oracle claims.”, and believes that this flaw “should have a CVSS score of 10.0”.


T-Mobile Suffers Second Breach of the Year

T-mobile has reported that it is the victim of its second data breach since the start of 2023. This latest attack was reported by T-Mobile on the 28th April, however, they estimate the attack occurred sometime between 24th February and 30th March. “The information obtained for each customer varied, but may have included full name, contact information, account number and associated phone numbers, T-Mobile account PIN, social security number, government ID, date of birth, [and] balance due,” said the company in a letter sent out to victims.


Ransomware Attack Affecting City Of Dallas IT Systems

The City of Dallas, Texas has reported a ransomware attack by the Royal Ransomware group on the city’s systems. The ransomware attack was reported to have shut down the city’s police communications, IT systems, and website. This led to the city’s court system suspending all jury trials and jury duty until the systems become operational. “Wednesday morning, the City’s security monitoring tools notified our Security Operations Center (SOC) that a likely ransomware attack had been launched within our environment. Subsequently, the City has confirmed that a number of servers have been compromised with ransomware, impacting several functional areas, including the Dallas Police Department Website," explained a media statement from the City of Dallas however no there has been no mention in how long it will take to recover from the attack.


Bitmarck shuts down customer and internal systems after a cyber attack.

Bitmarck, a German IT services provider, has reported that it had to shut down its customer and internal systems to protect customer, patient, and insured individual's data after an early warning system detected an active cyber attack incident over the weekend. “In compliance with our security protocol, we have taken down customer and internal systems from the grid in a controlled manner and conducted an impact analysis” states Bitmarck.  No data was thought to have been accessed in the attack and Bitmarck has since started bringing services back online including the digital processing of electronic incapacity certificates and access to electronic patient files. Many significant day-to-day services are still down due to data centers being disconnected from the network since the attack and there is no timeline for when the services will be up and running again.
