Following a spate of cyberattacks and data breaches affecting millions of Australians, the government‘s cybersecurity minister recently announced the formation of a task force that will hunt down hackers and said she is contemplating a ban on ransomware payments.
Cyberattackers love to strike on weekends and holidays - that's not news. What is news: These attacks cost more than weekday incidents, and they take a heavy toll on defenders. Cybereason's Sam Curry shares insight from the new study "Organizations at Risk: Ransomware Attackers Don’t Take Holidays."
Hospitals face attacks from nation-states seeking medical research and cybercriminals using pediatric patient data to apply for loans, says Stoddard Manikin. Adversaries target pediatric records to exploit the patient's credit and adult records when pursuing insurance or prescription fraud.
French defense multinational Thales confirmed that ransomware-as-a-service group LockBit published internal documents but emphasized its operations remain unaffected by the hack. The company says the source of the leak is likely a compromised user account of an online partner collaboration site.
A recent ransomware attack at a Texas hospital that knocked out phone and email systems for weeks is now even worse following OakBend Medical Center's admission that the hackers downloaded data from the medical records of up to 500,000 individuals.
The Australian government says hackers from Russia are behind the attack on Medibank, the country's largest private health insurer. Prime Minister Anthony Albanese said not just hackers but "the nation where these attacks are coming from should also be held accountable."
Police in Ontario arrested a dual Canadian-Russian national for his involvement with the LockBit ransomware-as-a-service gang. The United States is asking for the extradition of Mikhail Vasiliev, 33, to face a criminal charge in a New Jersey federal court of conspiracy to commit computer intrusion.
This edition of the ISMG Security Report discusses how Australian health insurer Medibank is facing stark consequences for not paying a ransom to a group of cyber extortionists, how to limit unnecessary cybersecurity exposure during M&A, and how to manage challenges in hybrid environments.
The stark consequences of ransomware became painfully clear in Australia this week as attackers began releasing data from health insurer Medibank, one of the country's largest health insurers. Also, leaked chat logs reveal how the attackers accessed Medibank's systems.
With massive digitization and cloud adoption, the attack surface has broadened and new threats have emerged. Challenges like ransomware, supply chain attacks and financial fraud continue to pose problems for security practitioners.
Who is attempting to extort Australian health insurer Medibank? Why did Medibank tell its attackers it wouldn't pay a ransom? Will this deter future cyber extortionists? Here are a few thoughts on the high cybercrime drama playing out.
Cybersecurity basics are still an overlooked ransomware defense, Lindy Cameron, CEO of the National Cyber Security Center, told the CyberScotland Summit in Scotland. "We still think that 90% of incidents in the U.K. could have been prevented if people had followed the basics," she said.
Embattled Australian private health insurer Medibank says it won't pay hackers' extortion demand, saying it can't trust cybercriminals to delete personal data. A ransomware gang claiming affiliation with REvil is threatening to publish the data, which Medibank says affects 9.7 million individuals.
Ransomware-as-a-service group LockBit is threatening the release of data it says it stole from German auto parts maker Continental. The company in August acknowledged an incident involving its IT systems, but didn't respond Friday with additional information.
In the latest weekly update, ISMG editors share how amateur tactics employed by ransomware gangs are leading fewer victims to pay ransoms, why traditional identity controls can't protect against the growing authorized payment scams, and highlights from ISMG's Crypto and Payments Summit.
