The hacker behind the attack that has hit the Société de transport de Montréal for ten days is now demanding a ransom of $ 2.8 million.
This request was made in a second communication with the hacker on Wednesday evening. The STM states, however, that it does not intend to comply with this request.
In a statement released Thursday, the Montreal public carrier explains that it was targeted by a ransomware-type attack that occurred as a result of a phishing email. The nature of the virus involved is not yet known and the investigation is continuing.
The STM announced at the beginning of last week a major outage that forced it to reduce its services, in particular for paratransit. The attack also disrupted its various platforms, including the website and telephone lines.
The cyberattack affected 1000 of the 1600 servers of the transport company, which specified Thursday that of this number, “624 are operationally sensitive servers”, but that “77% of these have been restored”.
The STM ensures that no data was stolen in the attack. The paratransit reservation system has now been re-established and the 11,000 employees have received their pay “in an almost normal manner”, it is indicated.
The bus and metro service, which was not affected by the attack, continues to operate normally.
