The Camembert didn't melt on its own

Summary

I walk through the 11 October cyberattack on hundreds of French supermarkets: attackers remotely switched on the fridges' automatic defrost by exploiting a flaw known since 2023, with no ransom and no data stolen. I explain why Spain is already on the list, from NoName057(16) to the ransomware that halted Damm, Hero and the Port of Vigo, and the 189 petrol stations whose tank valves were exposed online, as reported by ASPERTIC in 2018. An attack doesn't need to black out a country; being surgical is enough to erode trust, and NIS2 also reaches the suppliers of essential entities even though Spain has yet to transpose it.

Back to School (Cybersecurity Edition): cybersecurity training for executives — Antonio Fernandes, cybersecurity expert, on LinkedIn Artículo

Back to School (Cybersecurity Edition)

Summary

For many, September is the start of the year, and cybersecurity is still unfinished business, all the more so with Spain's Cybersecurity Coordination and Governance Act about to be published. I suggest three ways to catch up: my Cybersecurity Course for Executives, jargon-free and with a year of free advice, the in-person Nebrija Master's led by Enrique Cervantes, and the online EIP Master's led by Sergio Padilla.

The Story of the Little Hacktivist: phishing, a webshell and the legal limits of hacktivism — Antonio Fernandes, cybersecurity expert, on LinkedIn Artículo

The Story of the Little Hacktivist

Summary

After covering pro-Russian groups such as NoName057(16) on my channel, I tell another side of hacktivism: someone receives a phishing email impersonating Correos, finds the scammer's own webshell on the hacked site and renames index.php so victims no longer reach the card-stealing form, without deleting anything. However good it looks, hacking back is not legal, and there are lawful ways to help, from OSINT to find missing people to reporting paedophiles.

Hacking Venezuela's Elections

Summary

After the 2024 elections, Maduro spoke of a massive hack on the CNE's transmission system. I go through the history of Venezuelan e-voting, from Indra to Smartmatic, ExClé and the CANTV network, and explain that what the Attorney General describes is a denial of service that slowed the sending of tally sheets, which does not make one candidate's votes disappear. To me it is easier for whoever controls the machines, the network and the servers to cheat.

Remote Work Is Dead

Summary

I respond to criticism of remote work from Sam Altman, Elon Musk and José Elías with the Stanford research, which finds a 10% productivity drop in fully remote work but none in hybrid, and the University of Pittsburgh study on return-to-office mandates. I believe we are missing the chance to adapt, and that giving workers freedom would ease rural depopulation, rents, pollution and work-life balance.

Pegasus, the Best and Only Spyware

Summary

NSO Group's Pegasus is not the only one: before it came FinFisher and HackingTeam, and today Cy4gate, Nexa, Intellexa and Cytrox sell spying cyberweapons, as the Predator Files showed. I explain the use of zero-day vulnerabilities, which Mandiant saw grow by 50% in 2022, and remind readers that espionage also comes through our data and advertising, from Cambridge Analytica to AdInt.

Barefaced Scams

Summary

While Sora fascinates us, criminals swindled a multinational out of 24 million euros with a deepfake video call. I review the fake adverts with Marta Ortega or Antonio Resines that forced Spain's CNMV to issue a warning, sextortion with fake nudes such as the Almendralejo case, and propaganda, from the fake Biden robocall to the video of Zelensky surrendering. Against all this: projects like IVERES, reporting and critical thinking.
