Currently, I have not seen an actual "exploit" being used. But there is some evidence that people are scanning for vulnerable systems. Based on some of the errors made with these scans, I would not consider them "sophisticated." There is luckily still no public exploit I am aware of. --------------------------------------------- https://isc.sans.edu/diary/rss/25686 ∗∗∗ The Hidden Cost of Ransomware: Wholesale Password Theft ∗∗∗ --------------------------------------------- Moral of the story: Companies that experience a ransomware attack — or for that matter any type of equally invasive malware infestation — should assume that all credentials stored anywhere on the local network (including those saved inside Web browsers and password managers) are compromised and need to be changed. --------------------------------------------- https://krebsonsecurity.com/2020/01/the-hidden-cost-of-ransomware-wholesale… ∗∗∗ Breaking PHPs mt_rand() with 2 values and no bruteforce ∗∗∗ --------------------------------------------- .. one of our researchers was adamant that it was possible to recover the Mersenne Twister seed using only two outputs of the mt_rand() function, and without any kind of bruteforce. Nevertheless, we were unable to find any information supporting this theory, and his notes on the matter were long lost. After crunching the numbers a little bit, and years after the PRNG-prediction circus, we proved him right. --------------------------------------------- https://www.ambionics.io/blog/php-mt-rand-prediction ∗∗∗ SSH Client Auditing & Hardening ∗∗∗ --------------------------------------------- Its been known for years now that SSH servers can (and should) be hardened by removing weak default algorithms. For example, recent versions of OpenSSH ship with algorithms suspected suspected of being back-doored by the NSA (i.e.: ECDSA with the NIST P-curves), along with other algorithms with sub-128bit security levels.

One topic that was always debated is the reuse of existing code. Indeed, for a developer, its tempting to not reinvent the wheel when somebody already wrote a piece of code that achieves the expected results. From a gain of time perspective, its a win for the developers who can focus on other code.
