2021 Saw Record Numbers of DDoS Attacks on the Healthcare Industry
A new report from Comcast Business indicates 2021 was another record-breaking year for Distributed Denial of Service (DDoS) attacks. 9.84 million DDoS attacks were reported in 2021, which is a 14% increase from 2019, although slightly lower than the previous year when 10.1 million attacks were reported. The slight decline in attacks was due to several factors. 2020 was a particularly bad year as it was a full lockdown year where employees were working remotely and students were learning from home, which provided attackers with a unique landscape against which to launch an unprecedented number of DDoS attacks, and the high prices of cryptocurrencies in 2021 meant many threat actors diverted their botnets from conducting DDoS attacks to mining cryptocurrencies. DDoS attackers spared no one in 2021; however, 73% of attacks were conducted on just four sectors – healthcare, government, finance, and education. Attackers followed seasonal trends and activities throughout the year, with education being attacked to coincide with the school year, and COVID-19 and vaccine availability drove...
FBI Issues Warning About BlackCat Ransomware Operation
The Federal Bureau of Investigation (FBI) has issued a TLP: WHITE flash alert about the BlackCat ransomware-as-a-service (RaaS) operation. BlackCat, also known as ALPHAV, was launched in November 2021. It was launched shortly after the shutdown of the BlackMatter ransomware operation, which was a rebrand of DarkSide. Darkside was behind the ransomware attack on the Colonial Pipeline. A member of the operation has claimed they are a former affiliate of BlackMatter/DarkSide that branched out on their own. However, it is more likely that BlackCat is simply a rebrand of BlackMatter/DarkSide. The FBI said many of the developers and money launderers involved with the BlackCat operation have been linked to DarkSide/BlackMatter, which indicates they have extensive networks and considerable experience with running RaaS operations. The BlackCat RaaS operation has not been active for long, but the group has already claimed at least 60 victims worldwide. BlackCat typically targets large organizations and demands ransom payments of several million dollars in Bitcoin or Monero, although the...
HHS Issues Warning to HPH Sector about Hive Ransomware
The HHS’ Office of Information Security Health Sector Cybersecurity Coordination Center (HC3) has issued a TLP: White alert about the Hive ransomware group – A particularly aggressive cybercriminal operation that has extensively targeted the healthcare sector in the United States. HC3 has shared an analysis of the tactics, techniques, and procedures (TTPs) known to be used by the group in their attacks and has shared cybersecurity principles and mitigations that can be adopted to improve resilience against Hive ransomware attacks. The Hive ransomware group has been conducting attacks since at least June 2021. The group is known for using double extortion tactics, where sensitive data is exfiltrated prior to file encryption and threats are issued to publish the data if the ransom is not paid. The group is also known to contact victims by phone to pressure them into paying the ransom. Hive is a ransomware-a-service (RaaS) operation where affiliates are recruited to conduct attacks on the gang’s behalf in exchange for a cut of the profits that are generated, which allows the core...
