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 big picture: According to a new study by Kaspersky Lab, the defanged North Korea linked ransomware is still spreading uncontrollably. 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.

Pfizer-BioNTech: Booster doses more effective at blocking Omicron

Pfizer and BioNTech said Wednesday that two doses of their COVID-19 vaccine were significantly less effective at neutralizing the Omicron variant in early lab tests, but a three-dose regimen was more effective.

Why it matters: Omicron, which has been labeled a variant of concern by the World Health Organization after being identified by scientists in South Africa last month, has forced vaccine makers to reassess the effectiveness of their vaccines against this specific new form of coronavirus.

Social Democrat Olaf Scholz was sworn in as chancellor of Germany on Wednesday, succeeding Angela Merkel after 16 years and launching a new era of German and European politics.

Why it matters: Scholz, a center-left pragmatist who served as finance minister and vice chancellor in Merkel's last government, will lead Europe's largest economy in a coalition with the environmentalist Greens and pro-business Free Democrats.
