BR:  RecordTV allegedly a victim of an attack by ALPHV

News outlet RecordTV was allegedly the victim of an attack by ALPHV (aka BlackCat) on October 8th. The ransomware group has demanded approximately $5 million to provide a decryptor and not to leak the data.  Last week, ALPHV posted eight files as proof of access to the company. The files included spreadsheets, a passport, and a file related to litigation against them by an employee. The passport belongs to a well-known presenter of the station.

Because the attack disrupted programming, DataBreaches sent an email to RecordTV to ask about their current situation and if they have negotiated with the group. There has been no mention by them on their social networks about the attack, and we found no notice on their website. DataBreaches received no reply to an email inquiry sent yesterday. As of today, there is still no statement on their site or social media.

In response to our inquiry on Tox, the ALPHV spokesperson told us that they were negotiating with RecordTV, but would only say, “We are negotiating” and would not tell us more.

ES: Update on CSIC Cyberattack

DataBreaches previously reported that Consejo Superior de Investigaciones Científicas (CSIC), the Spanish National Research Center, suffered a ransomware attack in July. The attack was later claimed by Vice Society, who leaked the data they exfiltrated.

In an October 20 update, Eloísa del Pino, President of the CSIC, acknowledged that data had been exfiltrated during the attack and leaked on the dark web. She also described security improvements being implemented. “We have put in place all possible measures, five people were left without vacation working night and day,” she stated. On the advice of the police, CSIC did not pay the threat actors. Read more about her statement at EuropaPress.
