On the Evolution of Ransomware

Good article on the evolution of ransomware:

Though some researchers say that the scale and severity of ransomware attacks crossed a bright line in 2020, others describe this year as simply the next step in a gradual and, unfortunately, predictable devolution. After years spent honing their techniques, attackers are growing bolder. They’ve begun to incorporate other types of extortion like blackmail into their arsenals, by exfiltrating an organization’s data and then threatening to release it if the victim doesn’t pay an additional fee. Most significantly, ransomware attackers have transitioned from a model in which they hit lots of individuals and accumulated many small ransom payments to one where they carefully plan attacks against a smaller group of large targets from which they can demand massive ransoms. The antivirus firm Emsisoft found that the average requested fee has increased from about $5,000 in 2018 to about $200,000 this year.

Ransomware is a decades-old idea. Today, it’s increasingly profitable and professional.

Finnish Data Theft and Extortion

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2020/12/finnish-data-theft-and-extortion.html

The Finnish psychotherapy clinic Vastaamo was the victim of a data breach and theft. The criminals tried extorting money from the clinic. When that failed, they started extorting money from the patients:

Neither the company nor Finnish investigators have released many details about the nature of the breach, but reports say the attackers initially sought a payment of about 450,000 euros to protect about 40,000 patient records. The company reportedly did not pay up. Given the scale of the attack and the sensitive nature of the stolen data, the case has become a national story in Finland. Globally, attacks on health care organizations have escalated as cybercriminals look for higher-value targets.

Vastaamo said customers and employees had “personally been victims of extortion” in the case. Reports say that on Oct. 21 and Oct. 22, the cybercriminals began posting batches of about 100 patient records on the dark web and allowing people to pay about 500 euros to have their information taken down.
