Systems now part of global botnet
The Flashback Trojan targeting Macs has already infected at least 600,000 systems, according to an analyst with Russian antivirus firm Dr. Web. The company in fact issued a report on Wednesday mentioning 550,000 computers as contaminated by BackDoor.Flashback variants -- linked together in a botnet -- but the analyst in question quickly updated the information on Twitter. In the new data, 285 infected systems are mentioned as being in Finland, and 274 from Apple's own home city of Cupertino, California.
A graph in the report produced by Dr. Web has most infected systems, 56.6 percent, located in the United States. Canada is close behind at 19.8 percent, while the United Kingdom accounts for 12.8 percent, and Australia 6.1 percent. Most other regions are marginal in their infection rates, well under 1 percent each. Other affected countries include Argentina, Brazil, Chile, France, Germany, Ireland, Italy, Japan, Mexico, the Netherlands, the Philippines, Spain, Switzerland, and Turkey.
Earlier this week Apple released updated Java distributions for OS X Lion and Snow Leopard, dealing with a vulnerability exploited by Flashback. Apple has been criticized for being slow to patch the hole, especially as Oracle itself issued a fix in February.
