WannaCry, once the greatest cybersecurity calamity in history, now doesn't work. A website critical to its function is now controlled by civic-minded security researchers, and the fixed deadline to pay the ransom has long passed. Yet WannaCry still accounts for 28% of ransomware attacks — the most of any ransomware family.

The spreading mechanism that passed WannaCry from victim to victim that was so virulent in the 2017 attack is still active, even if the ransomware itself isn't. "This is not an uncommon occurrence, as there are multiple currently defunct worms that are still automatically spreading in the wild and infecting unpatched/unprotected machines," wrote Fedor Sinitsyn, senior malware analyst, via email.

Russian opposition leader Alexey Navalny was detained upon his return to Moscow on Sunday, which came five months after he was poisoned with the nerve agent Novichok. He returned despite being warned that he would be arrested.

The latest: Navalny was stopped at a customs checkpoint and led away alone by officers. He appeared to hug his wife goodbye, and his spokesman reports that his lawyer was not allowed to accompany him.

President-elect Biden has ordered up a shock-and-awe campaign for his first days in office to signal, as dramatically as possible, the radical shift coming to America and global affairs, his advisers tell us. 

The plan, Part 1 ... Biden, as detailed in a "First Ten Days" memo from incoming chief of staff Ron Klain, plans to unleash executive orders, federal powers and speeches to shift to a stark, national plan for "100 million shots" in three months.
