A user on a popular hacking forum is selling a database that
purportedly contains more than 257,000 user records from orakulas.lt
(now known as Olybet.lt), a Lithuanian online betting service. Olybet
is part of Olympic Entertainment Group, which is in turn owned by
private equity firm Novalpina Holding group.

The forum user is selling the login details – email addresses and
hashed passwords – of 257,510 orakulas.lt accounts for $100 in
bitcoin. At the same, five copies of another archive potentially
containing 3,087 tables that might include much more sensitive
personal data such as passports, ID card scans, and credit card
details of more than a quarter-million users, are being sold by the
same threat actor for $1500 in bitcoin.

Example of user data put for sale as seen in the screenshot on the hacker forum:

To confirm whether the database was genuine and whether Olybet was
aware of any breaches to their systems, we reached out to Tomas
Palevičius, General Manager of Olympic Casino Group Baltic.

Palevičius confirmed that the database seems to have belonged to
orakulas.lt, which was bought by Olybet and rebranded as olybet.lt in
2015. According to him, Olybet operates under a different license than
orakulas.lt and the databases used by Olybet are of a different
nature.

Palevičius stated that Olybet was not aware of any data leaks
following the rebrand from orakulas.lt. The company’s security
specialists, who are currently conducting an internal investigation
into the incident, have examined the entries included in the threat
actor’s screenshot and have not found any of the breached accounts in
Olybet databases, Palevičius said.

What was leaked?

Based on the samples we saw from the archive that is being sold for
$100, it contains user email addresses and passwords that have been
hashed using the weak SHA1 algorithm, which can be cracked by
cybercriminals without too much effort.

The threat actor claims to have cracked 49,476 out of 257,510
passwords, with the rest still unbreached before the database was put
up for sale.

The author of the forum post claims that the second part of the
database allegedly contains 3,087 tables that include a wide variety
of deeply sensitive personal and service-related data of orakulas.lt
users, such as:

Document scans
Credit card details
Personal messages
Bank account details
Transaction data

Example of data tables contained in the second orakulas.lt archive:

By investigating the screenshots of the database posted online by the
threat actor, we can see that the table begins with email addresses
containing old and obsolete email domains, many of which are no longer
used by Lithuanian users. With that being said, we cannot determine
the age of the database with absolute certainty because those are
merely the first entries in the table.

That, and the fact that the very first user account belongs to the
administrator of orakulas.lt, might indicate that these older email
addresses belonged to the users who were the first to sign up for the
online betting service, which would be consistent with the email
domains listed in the screenshot. This means that there is a
possibility that newer user records are present in the database.
