A security expert has told reporters that the recent hack on Adobe systems, affecting 2.9 million users, has meant all the computers running the software are now at risk of being attacked.
Hackers exploited Adobe systems and stole source code along with encrypted credit card numbers, as well as passwords and customer names.
"Our investigation currently indicates that the attackers accessed Adobe customer IDs and encrypted passwords on our systems," Adobe's Chief Security Officer Brad Arkin said.
"At this time, we do not believe the attackers removed decrypted credit or debit card numbers from our systems. We deeply regret that this incident occurred. We’re working diligently internally, as well as with external partners and law enforcement, to address the incident."
Director of Security Research at SpiderLabs, Ziv Mador said, however, that although credit card numbers may not have been stolen, the attackers can now analyse the stolen source code and identify vulnerabilities that were previously unknown.
Mador told South Africa's News24 that the hack means that even more resourceful companies may be successfully targeted and breached, and that they must take precautions and apply comprehensive security policy to minimize the risk of such breaches.
He went on to say that local enterprises should act to improve the security of critical data and networks as digital assets like credit card information, detailed customer information and other desired intellectual property are compelling for cybercriminals.
Adobe advised users to change their passwords, as well as change any passwords on other websites on which they may have used the same password. RT.com described the attack as possibly "the worst attack of its kind in the last 10 years."
