Citigroup: 360,000 credit cards compromised in recent hack

Remember Citigroup’s recent security breach? The firm originally said that 200,000 accounts — 1% of its customers — were compromised, but now Citi is going on record and saying that hackers gained access to a total of “360,083 North America Citi-branded credit cards.” Unfortunately, the company hasn’t provided any details on how the attack occurred, or who was behind it; the infamous hacking group LulzSec, which claimed responsibility for a number of recent high-profile targets including Sony, hasn’t yet mentioned any involvement. If you’re an optimist, the good news is that Citigroup says the number of active accounts affected is actually below the 360,000 figure — because of subsequent account closures — and that the hackers didn’t steal info enough to actually use the credit card numbers. 217,000 customers have already been provided with replacement cards, and California residents were hit the hardest — 80,000 of the numbers stolen were from that state.
