Tricking users at targeted organizations into installing legitimate remote monitoring and management software has become a familiar pattern employed by financially motivated attackers. After discovering the maliciously installed software on a system at one of the FCEB agencies, CISA went searching for and found more thusly compromised systems at other agencies.

Over several weeks in October of 2022, Specops collected 4.6 million attempted passwords on their honeypot system. Though the examples given here focused on RDP connections, a honeypot is not limited to that type of connection, and any remote access system is subject to attacks, like SSH. What should an organization do to minimize the potential damage?

Git has patched two critical severity security vulnerabilities that could allow attackers to execute arbitrary code after successfully exploiting heap-based buffer overflow weaknesses. A third Windows-specific flaw impacting the Git GUI tool caused by an untrusted search path weakness enables unauthenticated threat actors to run untrusted code low-complexity attacks.

Training, endpoint management reduce remote working cybersecurity risks
2023-01-17 04:30

"The popularity of hybrid work, and the associated risks, means that companies must prioritise training and education to make remote working safe. Traditional methods of controlling and securing company data aren't as effective when employees are working in remote locations and greater responsibility falls on the individual. Companies must acknowledge the unique risks associated with remote work and activate relevant security management systems, as well as empower employees to deal with a certain level of risk," said Daniel Hofmann, CEO of Hornetsecurity. Hofmann commented: "Increasing remote working cybersecurity measures is particularly important in the current climate, as cybercriminals are becoming smarter and using remote working to their advantage. We've seen an increase in smartphone attacks as hackers understand that both personal and professional data can likely be accessed as people can, and often do, carry out work on personal devices."

One popular use of JSON is the JWT system, which isn't pronounced jer-witt, as it is written, but jot, an English word that is sometimes used to refer the little dot we write above above an i or j, and that refers to a tiny but potentially important detail. Loosely speaking, a JWT is a blob of JavaScript that is used by many cloud services as a service access token.
