Researchers at the security firm Netlab have identified a previously undocumented botnet dubbed "Matryosh" that is targeting vulnerable Android devices to help build its network so it can conduct distributed denial-of-service attacks.
The operators behind the Trickbot malware are deploying a new reconnaissance tool dubbed "Masrv" to exfiltrate additional data from targeted networks, according to a Kryptos Logic report. Other researchers have noticed increases in the botnet's activity over the last month.
Alejandro Mayorkas, the newly confirmed secretary of the Department of Homeland Security, says his initial priorities include reviewing all available intelligence on the SolarWinds supply chain hack and scrutinizing the government's cybersecurity programs.
Ransomware operations continue to come and go. The notorious Maze ransomware gang retired last year, apparently replaced by Egregor, while new operators, such as Pay2Key, RansomEXX and Everest, have emerged. But in recent months, experts say, just six operations have accounted for 84% of attacks.
The operators behind the Agent Tesla remote access Trojan have updated the malware to enable it to disable endpoint protection software and have added features to hide communications, according to a report from the security firm Sophos.
To take down bigger targets more easily and quickly, ransomware gangs are increasingly tapping initial access brokers, who sell ready access to high-value networks. Economically speaking, it's a no-brainer move for cybercrime gangs.
Up to 30% of the organizations hit as part of the cyberespionage campaign waged by the hackers responsible for the SolarWinds supply chain attack did not use the company’s compromised software, says Brandon Wales, acting director of CISA. These victims were targeted in a variety of other ways, he says.
The law enforcement agencies behind this week's disruption - dubbed “Operation Ladybird” - of Emotet are helping victims by pushing out an update via the botnet’s infrastructure that will disconnect their devices from the malicious network.
Researchers at the security firm RiskIQ have discovered a phishing kit they call "LogoKit" that fraudsters can use to easily change lures, logos and text in real time to help trick victims into opening up messages and clicking on malicious links.
In the past, when threat actors were less advanced and when digital activity was more predictable, a traditional approach to security was often adequate to keep cyber-threats at bay. By configuring security tools with static rules and historical attack data, organizations have sought to detect threats by defining...
North Korean hackers have been "targeting security researchers working on vulnerability research and development at different companies and organizations" to trick them into installing backdoored software that gives attackers remote access to their systems, warns Google's Threat Analysis Group.
Email security vendor Mimecast confirmed Tuesday that the hackers responsible for the SolarWinds supply chain hack also breached the security firm's network to compromise a digital certificate that encrypts data that moves between some of the firm's products and Microsoft's servers.
Once a catalogue merchant, The Very Group is now one of the UK’s largest digital retailers. And with transformation came significant cybersecurity challenges. Michael Duncan of The Very Group and Hitesh Sheth, CEO of Vectra AI, discuss the path to automated threat detection and response.
