Kaspersky Lab cybersecurity firm is hacked
June 11, 2015
Kaspersky Lab said it believed the attack was designed to spy on its newest technologies.
It said the intrusion involved up to three previously unknown techniques.
The Russian firm added that it was continuing to carry out checks, but believed it had detected the intrusion at an early stage.
Although it acknowledged that the attackers had managed to access some of its files, it said that the data it had seen was "in no way critical to the operation" of its products.
"Spying on cybersecurity companies is a very dangerous tendency," said the company's chief executive Eugene Kaspersky.
"The only way to protect the world is to have law enforcement agencies and security companies fighting such attacks openly.
"We will always report attacks regardless of their origin."
Kaspersky Lab said that it had detected the breach in the "early spring", and described it as "one of the most sophisticated campaigns ever seen".
The malware does not write any files to disk, but instead resides in affected computers' memory, making it relatively hard to detect.
Kaspersky linked the attack to the unidentified creators of an earlier Trojan named Duqu, which made headlines in 2011 after being used in attacks on Iran, India, France and Ukraine.
