Feds Share Technical Details of Royal Ransomware
A joint cybersecurity advisory has been published by CISA and the FBI, sharing details of the tactics, techniques, and procedures (TTPs) used by the Royal ransomware gang and Indicators of Compromise (IoCs) to help network defenders better protect against attacks. Royal Ransomware is a relatively new threat actor that was first observed conducting attacks in 2022. The group is believed to consist of highly experienced cybercriminals who are well-versed in conducting ransomware attacks, including operators that were once part of Conti Team One. Conti was one of the most prolific ransomware groups over the past 3 years and was formed by the group behind Ryuk ransomware. Royal has previously used the encryptors of other ransomware operations, then switched to using its own – Royal – in September 2022, and has now overtaken Lockbit to become the main player in the ransomware market. Like Conti and Ryuk before it, the Royal ransomware group is focused on attacks in the United States, especially critical infrastructure entities, including those operating in the healthcare and...
Ransomware Gang Ups the Ante by Publishing Naked Images of Patients
In what is believed to be a first, the BlackCat ransomware gang has published naked images of patients that were stolen in one of its attacks on a healthcare organization in an attempt to pressure the victim into paying the ransom. Lehigh Valley Health Network (LVHN) recently announced that it was dealing with a ransomware attack that was detected on February 6, 2023. LVHN confirmed that the BlackCat ransomware group was behind the attack and had issued a ransom demand, payment of which would see the decryption keys provided and would prevent the release of data stolen in the attack. Brian A. Nester, LVHN President and CEO, confirmed that LVHN refused to pay the ransom and operations were unaffected. Nester said the attack was on the network supporting a physician practice in Lackawanna County and the computer system involved stored clinically appropriate patient images for radiation oncology treatment and other sensitive patient information. “Attacks like this are reprehensible and we are dedicating appropriate resources to respond to this incident,” said Nester. In an attempt to...
HSCC & HHS Release Guide to Help Healthcare Organizations Adopt the NIST Cybersecurity Framework
A new guide has been published by the Health Sector Coordinating Council (HSCC) Cybersecurity Working Group and the U.S. Department of Health and Human Services (HHS) to help healthcare organizations align their cybersecurity programs with the NIST Framework for Improving Critical Infrastructure Cybersecurity. The NIST Cybersecurity Framework is one of the most widely adopted frameworks for identifying and managing cybersecurity risks. The framework was released by NIST in 2015, updated in 2018, and the NIST CSF 2.0 is due for release later this year. The NIST CSF is based on five core functions – Identify, Protect, Detect, Respond, and Recover – and suggests cybersecurity controls that can be implemented in all five functional areas. The framework also includes four tiers against which organizations can rate their adoption of the framework, which allows them to communicate how there are achieving their cybersecurity objectives in a standardized way. The NIST CSF has become the standard cybersecurity framework for government agencies and private sector companies for managing...
PII of Lawmakers and Capitol Hill Staff Stolen in DC Health Link Data Breach
The personal information of lawmakers and staffers has been stolen in a cyberattack on the health insurance marketplace, DC Health Link. DC Health Link serves around 100,000 people, including 11,000 Congress members and staffers. The investigation into the data breach is still in the early stages so it is currently unclear how many Congress members and staffers have been affected. At this stage of the investigation, it appears that the hacker behind the attack did not specifically target the personally identifiable information (PII) of members of Congress or the House of Representatives. House Chief Administrative Officer, Catherine Szpindor, issued a statement confirming there had been “a significant data breach” that potentially involved the theft of the PII of thousands of enrollees. She said the Federal Bureau of Investigation (FBI) has been assisting with the investigation and believes the PII of hundreds of Congress members and staffers has been stolen. She also confirmed that some DC Health Link Customer data has been exposed on a public forum. An investigation is currently...
Cybercriminals Adopt Corporate Tactics to Address Declining Revenues
Cybercriminal groups have been experiencing declining revenues. Just like the businesses they attack, when profits start to fall, changes need to be made. Cybercriminal groups appear to be mirroring legitimate businesses and are using similar tactics when faced will falling profits, according to a recent report from Trend Micro. Ransomware gangs in particular have seen profits take a nosedive, with ransom payments decreasing by 38% year-over-year as victims refuse to pay up, even when there is the threat of publication of stolen data. The gangs have responded by changing their tactics and are becoming more professional. When their brand image becomes tarnished, they simply rebrand. This helps them to stay under the radar but also deals with the image crisis. Conti, one of the most prominent, active, and professional ransomware groups, disbanded when the brand became toxic, with its members splitting into several smaller groups such as Black Basta, Karakurt, Royal, and BlackByte. Cybercriminal groups have started diversifying their portfolios, placing less reliance on the ransomware...
