Perchè i loro half-time show ormai sono una roba che non ci si crede. Dopo quello dell’anno scorso a tema videogiochi, stavolta ne hanno fatto uno, forse ancora migliore, a tema hollywoodiano:

Sono obbligato a postare il trailer del finto film Daria’ High School Reunion, anche se la cosa mi causa reazioni contrapposte: da un lato mi esalta perchè è troppo bello per essere vero (Aubrey Plaza è PERFETTA, ed è strapieno di dettagli brillanti), e dall’altro mi intristisce perchè, beh, non è vero, e il film non esiste. Per ora.

Sì, è quello che credete. Tipo la cosa nerd più figa di sempre.

E' un po' lungo e in alcuni punti un po' tecnico, ma l'articolo di Ars technica che spiega per quale motivo le nostre password fanno acqua da tutte le parti e sono molto facili da crackare merita assolutamente la lettura: 

The ancient art of password cracking has advanced further in the past five years than it did in the previous several decades combined. At the same time, the dangerous practice of password reuse has surged. The result: security provided by the average password in 2012 has never been weaker.

 

The average Web user maintains 25 separate accounts but uses just 6.5 passwords to protect them, according to a landmark study (PDF) from 2007. As the Gawker breach demonstrated, such password reuse, combined with the frequent use of e-mail addresses as user names, means that once hackers have plucked login credentials from one site, they often have the means to compromise dozens of other accounts, too.

 

Newer hardware and modern techniques have also helped to contribute to the rise in password cracking. Now used increasingly for computing, graphics processors allow password-cracking programs to work thousands of times faster than they did just a decade ago on similarly priced PCs that used traditional CPUs alone. A PC running a single AMD Radeon HD7970 GPU, for instance, can try on average an astounding 8.2 billion password combinations each second, depending on the algorithm used to scramble them. Only a decade ago, such speeds were possible only when using pricey supercomputers.

 

The advances don't stop there. PCs equipped with two or more $500 GPUs can achieve speeds two, three, or more times faster, and free password cracking programs such as oclHashcat-plus will run on many of them with little or no tinkering. Hackers running such gear also work in tandem in online forums, which allow them to pool resources and know-how to crack lists of 100,000 or more passwords in just hours.

 

Most importantly, a series of leaks over the past few years containing more than 100 million real-world passwords have provided crackers with important new insights about how people in different walks of life choose passwords on different sites or in different settings. The ever-growing list of leaked passwords allows programmers to write rules that make cracking algorithms faster and more accurate; password attacks have become cut-and-paste exercises that even script kiddies can perform with ease.
