The data dump of citizens' election information following a ransomware attack against a county in Georgia is likely to raise concerns about the integrity of this year's vote, some security experts say.
The FBI and CISA warn U.S. hospitals about a fresh wave of Ryuk ransomware attacks that have recently targeted healthcare facilities across the country. Over the past week, several hospitals have publicly reported attacks, which appear to be financially motivated.
The operators behind the Ryuk strain of malware are increasingly relying on a malware-as-a-service tool - the Buer loader - to deliver the malware, rather than botnets such as Trickbot and Emotet, the security firm Sophos reports.
The imperative for CISOs during the COVID-19 pandemic is to do more with less. While disruptive attacks - as well as privacy concerns - keep rising, budgets are down. As organizations rapidly adopt new technologies, however, EY's Kris Lovejoy says CISOs must seize the opportunity to streamline.
"Cybercrime is an evolution, not a revolution," says Europol's Philipp Amann, who oversees the EU law enforcement intelligence agency's annual study of the latest cyber-enabled crime trends. Ransomware, social engineering and the criminal abuse of cryptocurrency and encryption are some of the top threats.
U.S. intelligence officials say a Russia-backed hacking group has compromised some state and local government computer systems since at least September and exfiltrated data. So far, however, the attackers do not appear to have attempted to otherwise interfere with or disrupt those networks.
The operators behind the LockBit ransomware strain use automation tools and techniques that help the malware quickly spread through a compromised network and also assist in picking specific targets, according to Sophos.
Microsoft and its partners are continuing to put pressure on the Trickbot malware operation, eliminating an estimated 94% of its infrastructure. But some security researchers warn that the botnet's operators are developing workarounds to re-establish its infrastructure, enabling the group to resume its activities.
The U.S. Justice Department unsealed indictments against six Russian military officers on Monday, alleging that they carried out a series of major hacking operations, including deploying destructive NotPetya malware - tied to more than $10 billion in damages - and attacking the 2018 Olympics.
To mitigate the risks posed by ransomware attacks, enterprises need to move from file-based security to a behavior-based approach, says Jennifer Ayers, vice president of the OverWatch division of Crowdstrike.
