Background for this topic.

Extortion is coercion through threats: an attacker demands money or another concession while threatening harm if the victim refuses. In cybersecurity, this commonly involves encrypting systems and demanding payment for recovery, stealing data and threatening to publish it (often called double extortion), or threatening service disruption. The threatened harm may be real, exaggerated, or based on data the attacker did not actually obtain; payment does not guarantee data deletion, secrecy, or restoration.

Security teams should treat an extortion demand as a potential incident: preserve evidence, isolate affected systems, determine whether data was accessed, and involve legal and privacy specialists where notification or regulatory duties may apply. Offline, tested backups can reduce leverage from encryption, but they do not address stolen information. Reviewing exposed remote services, credentials, and unpatched internet-facing systems can help contain the access path, while threat intelligence may help assess the attacker’s claims and identify related activity.

Canvas Breach Disrupts Schools & Colleges Nationwide

An ongoing data extortion attack targeting the widely-used education technology platform Canvas disrupted classes and coursework at school districts and universities across the United States today, after a cybercrime group defaced the service's login page with a ransom demand that threatened to leak data from 275 million students and faculty across nearly 9,000 educational institutions.

An elusive hacker who went by the handle "UNKN" and ran the early Russian ransomware groups GandCrab and REvil now has a name and a face. Authorities in Germany say 31-year-old Russian Daniil Maksimovich Shchukin headed both cybercrime gangs and helped carry out at least 130 acts of computer sabotage and extortion against victims across the country between 2019 and 2021.

ShinyHunters Wage Broad Corporate Extortion Spree

A cybercriminal group that used voice phishing attacks to siphon more than a billion records from Salesforce customers earlier this year has launched a website that threatens to publish data stolen from dozens of Fortune 500 firms if they refuse to pay a ransom. The group also claimed responsibility for a recent breach involving Discord user data, and for stealing terabytes of sensitive files from thousands of customers of the enterprise software maker Red Hat.

Incognito Darknet Market Mass-Extorts Buyers, Sellers

Borrowing from the playbook of ransomware purveyors, the darknet narcotics bazaar Incognito Market has begun extorting all of its vendors and buyers, threatening to publish cryptocurrency transaction and chat records of users who refuse to pay a fee ranging from $100 to $20,000. The bold mass extortion attempt comes just days after Incognito Market administrators reportedly pulled an "exit scam" that left users unable to withdraw millions of dollars worth of funds from the platform.

There are indications that U.S. healthcare giant Change Healthcare has made a $22 million extortion payment to the infamous BlackCat ransomware group (a.k.a. "ALPHV") as the company struggles to bring services back online amid a cyberattack that has disrupted prescription drug services nationwide for weeks. However, the cybercriminal who claims to have given BlackCat access to Change's network says the crime gang cheated them out of their share of the ransom, and that they still have the sensitive data that Change reportedly paid the group to destroy. Meanwhile, the affiliate's disclosure appears to have prompted BlackCat to cease operations entirely.

Alleged Extortioner of Psychotherapy Patients Faces Trial

Prosecutors in Finland this week commenced their criminal trial against Julius Kivimäki, a 26-year-old Finnish man charged with extorting a once popular and now-bankrupt online psychotherapy practice and thousands of its patients. In a 2,200-page report, Finnish authorities laid out how they connected the extortion spree to Kivimäki, a notorious hacker who was convicted in 2015 of perpetrating tens of thousands of cybercrimes, including data breaches, payment fraud, operating a botnet and calling in bomb threats.

A Retrospective on the 2015 Ashley Madison Breach

It's been seven years since the online cheating site AshleyMadison.com was hacked and highly sensitive data about its users posted online. The leak led to the public shaming and extortion of many AshleyMadison users, and to at least two suicides. To date, little is publicly known about the perpetrators or the true motivation for the attack. But a recent review of AshleyMadison mentions across Russian cybercrime forums and far-right underground websites in the months leading up to the hack revealed some previously unreported details that may deserve further scrutiny.

Costa Rica’s national health service was hacked sometime earlier this morning by a Russian ransomware group known as Hive. The intrusion comes just weeks after Costa Rican President Rodrigo Chaves declared a state of emergency in response to a data ransom attack from a different Russian ransomware gang — Conti. Ransomware experts say there is good reason to believe the same cybercriminals are behind both attacks, and that Hive has been helping Conti rebrand and evade international sanctions targeting extortion payouts to cybercriminals operating in Russia.

The Original APT: Advanced Persistent Teenagers

Many organizations are already struggling to combat cybersecurity threats from ransomware purveyors and state-sponsored hacking groups, both of which tend to take days or weeks to pivot from an opportunistic malware infection to a full blown data breach. But few organizations have a playbook for responding to the kinds of virtual "smash and grab" attacks we've seen recently from LAPSUS$, a juvenile data extortion group whose short-lived, low-tech and remarkably effective tactics are putting some of the world's biggest corporations on edge.
