The personal information of 237,000 former and current employees of the ministry was hacked.
Unidentified hackers hacked into the US Department of Transportation (DOT) computer network and gained access to the personal data of at least 237,000 current and former employees of the department. This was reported by local media, citing a DOT statement.
According to the ministry, the cyber attack did not affect transport security systems, but it has not yet been possible to establish its source and motives. In a letter sent by DOT to the US Congress, it says that the hack affected certain systems of the administrative department, in particular, TRANServe's transportation benefits processing systems.
DOT also confirmed that it is not yet known whether the stolen data was used for criminal purposes. Of the 237,000 victims, 14,000 are active employees of the ministry, and 123,000 are former.
The attack came amid a warning from US President Joe Biden about possible cyberattacks by Russia in response to Western sanctions over the crisis in Ukraine. Biden called on the US private sector to "immediately" beef up its cyber defenses and said the US government is using "every tool" to counter Russian hackers.
