The excellent post-mortem of the City of Helsinki data breach (summary at turvallisuustutkinta.fi/en/ind, link to the full report at the bottom) says one thing I'm suspicious of. See screenshots below.
Problem: FileZilla server supports on-the-fly encryption, and 70% is a typical compression ratio for a heterogeneous data stream. To me, it seems possible (perhaps even likely) that the attacker downloaded _all_ the data with compression, not just 30% of it.

"Due to inadequate log data, only an approximate idea of the numbers of leaked files can be formed. The files were downloaded to the attacker's server using a FileZilla’s encrypted FTP. The total volume of traffic could be determined from firewall logs, but due to encryption, file names or other details could not be established."
"Based on the total data volume (two terabytes) the attacker downloaded in proportion to the total number of files on the network drive (6.73 terabytes), it can be estimated that 30% of the files were copied. In other words, the attacker gained access to around 1.3 million files, of which around 750,000 were documents (Office and PDF files)."

I could sing this man's praises for a hundred years.
Last Sunday I witnessed, for my second time, the live performance by this Lyonese synth wizard whose music has always inspired me to think outside the box, be it in photography or graphic design of any kind, or life in general.
Quel concert merveilleux! À la prochaine Jean-Michel!

Tekis ihan hirveesti mieli lähteä Saimaa Cycle Touriin, mutta Imatralta ei pääse junalla takaisin Stadiin ennen tiistaita, kun kaikki pyöräpaikat on myyty loppuun. (Kiitos VR ja runsaat kuljetuskapasiteetit.)

Oisko sattumalta ketään autolla Helsingistä menossa, jolla olis tilaa pyörälle ja mieluusti myös kuskille? Kuski toki voi kulkea junalla, jos tsygän saa auton kyytiin.
