Has the notorious REvil, aka Sodinokibi, ransomware operation rebooted as "Ransom Cartel"? Security experts say the new group has technical and other crossovers with REvil. But whether the new group is a spinoff of REvil, bought the tools, or is simply copying how they work, remains unclear.
U.S. President Joe Biden today signed a National Security Memorandum that aims to improve the cybersecurity of national security systems. The memo gives new powers to the NSA to oversee cybersecurity improvements such as the use of the multifactor authentication, encryption and endpoint detection services.
"We came up with a structured, documented approach to respond to mitigating the Log4j vulnerability using the EDR scanning tools along with a code validation, containerization, and sandboxing of our applications and networks," says Ian Keller, security director at Ericsson.
OK, so the trend is away from endpoint detection and response to extended detection and response. What does that even mean, and how can organizations get maximum cybersecurity protection from this shift? Cisco's Brian McMahon shares insight.
The current state of the XDR market is a "chaotic jumble of different features," according to Forrester analyst Allie Mellon, who has authored a new study to identify the top XDR providers in the industry: The Forrester New Wave: Extended Detection And Response (XDR) Providers, Q4 2021.
Israeli officials say they have fended off a wave of attempted cyberattacks on several hospitals and healthcare entities in recent days, as Hillel Yaffe Medical Center continues to recover from a ransomware attack last week that authorities reportedly suspect was carried out by Chinese hackers.
Criminal hackers don't break for lunches, weekends or holidays. Of course, that's just one of many challenges facing information security teams, as they attempt to maximize visibility and minimize complexity while protecting their business around the clock, says Peter Van Lierde, the CISO of energy firm Sibelga.
As the risks to IT and OT converge, organizations must use "zero trust" to verify user identities and build effective monitoring capabilities to track the behavior of privileged users, say Kartik Shahani of Tenable and Rohan Vaidya of CyberArk.
The Ragnar Locker ransomware operation has been threatening to dump victims' stolen data if they contact police, private investigators or professional negotiators before paying a ransom. But as one expert notes: "Perhaps the criminals watched too many TV shows, because this isn’t how the real world works."
The most sought-after type of victim for ransomware-wielding attackers is a large, U.S.-based business with at least $100 million in revenue, not operating in the healthcare or education sector, with remote access available via remote desktop protocol or VPN credentials, threat intelligence firm Kela reports.
By some estimates, the managed security services business is expected to grow by 50% between 2020 and 2025. And a huge part of that growth will by XDR, says Colin O'Connor, COO of ReliaQuest. He explains why XDR is far more than just vendor hype.
