GHSA-G8WG-CJWC-XHHP Heap OOB in nested `tf.map_fn` with `RaggedTensor`s

Impact It is possible to nest a tf.mapfn within another tf.mapfn call. However, if the input tensor is a RaggedTensor and there is no function signature provided, code assumes the output is a fully specified tensor and fills output buffer with uninitialized contents from the heap: python import...

Researchers Warn of 4 Emerging Ransomware Groups That Can Cause Havoc

Cybersecurity researchers on Tuesday took the wraps off four up-and-coming ransomware groups that could pose a serious threat to enterprises and critical infrastructure, as the ripple effect of a recent spurt in ransomware incidents show that attackers are growing more sophisticated and more...

Analysts “strongly believe” the Russian state colludes with ransomware gangs

"We have the smoke, the smell of gunpowder and a bullet casing. But we do not have the gun to link the activity to the Kremlin." This is what Jon DiMaggio, Chief Security Stretegist for Analyst1, said in an interview with CBS News following the release of its latest whitepaper, entitled "Nation...
