This is the second time the CCleaner app has been the victim of an attempt or even a cyberattack.

She made the case of the private virtual network, without any security authentication to protect a potential user: "It was in principle a temporary account, the kind of account created for a particular task such as a backup or an administration operation. It was the only VPN account for which strong authentication was not enabled and it should have been deleted, but it was not.

He hid at the bottom of the VPN account directory, and the attacker used it after he managed to steal the ID and password. But we don't know yet how he did it," she said. However, this is not a false positive because if there was a black spot that should have resulted from a misinterpretation, the technicians had security alerts that caused them to lose a lot of time.

Indeed, on September 23, the team of experts of the cybersecurity firm had noticed that there were inconsistencies in the login. This is where they saw a user connected to a VPN network from a Mac terminal, even though the user had no permission to be there. Unfortunately this irregular action was passed off as a false positive, thus an error in the logs: "However, an investigation has been launched for verification.

But the priority software for business, because that is where the impact of a business infection is the highest," the official said.

In addition, the VPN account Temporary service was put into service: "It was the right thing to do in not to attract the striker's attention,"

The first manager assured that the teams are in the process of verifying all the logs they have, and that the identifiers have already been reset. "Imagine you have a house and in a room you have seen termites. Are they also in another room? Did they infest the whole house? We don't know. I preferred to assume that all the infrastructure is compromised and that we had to start from scratch," explained Baloo.
