JavaGhost exploits AWS misconfigurations to run phishing campaigns via SES and WorkMail, evading email protections.
The next step involves fetching and executing a Python script from the same SharePoint location that serves as a shellcode loader for KaynLdr, a reflective loader written in C and ASM that’s capable of launching an embedded DLL, in this the Havoc Demon agent on the infected host.
“The threat actor uses Havoc in conjunction with the MicrosoQ Graph API to conceal C2 communication within well-known services,” Fortinet said, adding the framework supports features to gather information, perform file operations, as well as carry out command and payload execution, token manipulation, and Kerberos attacks.
The development comes as Malwarebytes revealed that threat actors are continuing to exploit a known loophole in Google Ads policies to target PayPal customers with bogus ads served via advertiser accounts that may have been compromised.

“A good ratio of oxygen to methane is key to combustion,” said Justin Long.
Can methane flare burners be advanced to produce less methane? This is what a recent study published in Industrial & Engineering Chemistry Research hopes to address as a team of researchers from the University of Michigan (U-M) and the Southwest Research Institute (SwRI) developed a methane flare burner with increased combustion stability and efficiency compared to traditional methane flare burners. This study has the potential to develop more environmentally friendly burners to combat human-caused climate change, specifically since methane is a far larger contributor to climate change than carbon dioxide.
For the study, the researchers used a combination of machine learning and novel manufacturing methods to test several designs of a methane flare burner that incorporates crosswinds to simulate real-world environments. The burner design includes splitting the methane flow in three directions while enabling oxygen flow from crosswinds to mix with the methane, enabling a much cleaner combustion. In the end, the researchers found that their design achieves 98 percent combustion efficiency, meaning it produces 98 percent less methane than traditional burners.
“A good ratio of oxygen to methane is key to combustion,” said Justin Long, who is a Senior Research Engineer at SwRI. “The surrounding air needs to be captured and incorporated to mix with the methane, but too much can dilute it. U-M researchers conducted a lot of computational fluid dynamics work to find a design with an optimal air-methane balance, even when subjected to high-crosswind conditions.”
Georg Ferdinand Ludwig Philipp Cantor (/ ˈ k æ n t ɔːr / KAN-tor; German: [ˈɡeːɔʁk ˈfɛʁdinant ˈluːtvɪç ˈfiːlɪp ˈkantoːɐ̯] ; 3 March [O.S. 19 February] 1845 – 6 January 1918 [ 1 ] ) was a mathematician who played a pivotal role in the creation of set theory, which has become a fundamental theory in mathematics. Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are more numerous than the natural numbers. Cantor’s method of proof of this theorem implies the existence of an infinity of infinities. He defined the cardinal and ordinal numbers and their arithmetic. Cantor’s work is of great philosophical interest, a fact he was well aware of. [ 2 ]
Originally, Cantor’s theory of transfinite numbers was regarded as counter-intuitive – even shocking. This caused it to encounter resistance from mathematical contemporaries such as Leopold Kronecker and Henri Poincaré [ 3 ] and later from Hermann Weyl and L. E. J. Brouwer, while Ludwig Wittgenstein raised philosophical objections; see Controversy over Cantor’s theory. Cantor, a devout Lutheran Christian, [ 4 ] believed the theory had been communicated to him by God. [ 5 ] Some Christian theologians (particularly neo-Scholastics) saw Cantor’s work as a challenge to the uniqueness of the absolute infinity in the nature of God [ 6 ] – on one occasion equating the theory of transfinite numbers with pantheism [ 7 ] – a proposition that Cantor vigorously rejected.
