In the absence of reaction, the hackers move up a gear.
Almost three months after the cyberattack on the town hall of Mitry-Mory (Seine-et-Marne), the group of cybercriminals "
DoppelPaymer
" claimed, this Tuesday, its intrusion on the computer network of the municipality, according to information from the
Parisian
.
An announcement accompanied by a ransom demand and a disclosure of some data as a threat.

"
Nothing new
", we sigh to the municipality, which does not wish to communicate on the amount of the sum claimed.
The request was published on the Dark Web but "
we have not received any notification from them
", confides the administration to
Le Figaro
.
As for the allegedly published data, "
there is no evidence that they are sensitive, usable or even up to date
."
The Mitry-Mory town hall operating system returned to “
normal
”
functioning
a month after the attack.
The use of "
ransomware
", or
ransomware
, is often the same.
“
Hackers find a way to infiltrate a network, map it and destroy backups.
They then launch the ransomware that encrypts the data and makes them inaccessible,
”explains Jérôme Notin, director of cybermalveillance.gouv.fr, an assistance system for victims of cyberattacks.
In the case of small structures, such as that of the town hall of Mitry-Mory, the pressure is relative.
“
For SMEs or local authorities, the problem is more that of the confiscation of data, essential for working, than of their disclosure.
On the other hand, this can be problematic for larger companies which hold more sensitive information
”, indicates Jérôme Notin.
Cyber attacks boom in full containment
The town hall of Mitry-Mory is far from being an isolated case.
“
Traffic to our site has exploded with the lockdown.
Visits to our platform have increased by 400%,
”says Jérôme Notin.
Teleworking has indeed increased the potential targets of hackers.
“
He set up very quickly, often without a suitable security system.
Many employees have even used their personal computers to work,
”explains the director.
Ransomware cyber attacks are a massive phenomenon.
"
We are used to saying: 'do not ask yourself if you are going to be attacked but when you are going to be,"
"smiles Jérôme Notin.
To protect yourself, the expert advises to back up your data outside the network.
“
You can use an external backup, like a hard drive.
For larger structures, professional backup systems exist: they allow automatic disconnection from the network after backup,
”explains the director, inviting victims to never pay a ransom.
“
Paying does not prove that your data will be returned to you.
In addition, you risk being identified as a '' good customer '' in the cybercrime world
