American organization MITRE announced the release of a new 10th version of the ATT&CK matrix. The release updates Techniques, Groups, and Software for Enterprise, Mobile, and ICS.
The biggest change was an update to the Data Source and Data Component structure in the Enterprise ATT&CK. The matrix now fully aggregates the information from these structures into itself, allowing you to conveniently discover the relationships between the data object and the possible variations of sub-techniques implemented on their basis. In total, the 10th version of the MITRE ATT&CK matrix contains 14 tactics, 188 methods, 379 sub-techniques, 129 groups, and 638 programs.
The first evidence that someone had hacked the National Register of Persons (Registro Nacional de las Personas – the agency that issues passports of citizens) appeared on Twitter earlier this month. A user under the account @AnibalLeaks posted photos of the personal data of 44 Argentinean celebrities.
In a press release on October 13, Argentina’s Ministry of the Interior announced that a VPN account assigned to the Ministry of Health was used to query the agency’s database “at the very moment the data was posted to Twitter”. The hacker, whom The Record reporters managed to contact, indirectly confirmed the version of the Argentine Ministry of Internal Affairs.
In a Gummy Browsers attack, attackers trap a victim to their website in order to obtain their digital fingerprint, which can be used to spoof the victim’s identity on the target platform. The researchers said that by using the Gummy Browsers method, they can trick modern digital fingerprint tracking systems such as FPStalker and Panopticlick for a long time. Digital fingerprint data can be used to bypass authentication (MFA) and fraud detection mechanisms used by many banks and large retailers.
