There's good news on the Zeus Gameover Trojan and Cryptolocker ransomware campaigns: The number of new infections has become "very low," if not fallen to zero. But related attacks could quickly resurge. Learn the reasons why.
Security researchers say the international takedown of the Gameover Zeus botnet and servers for CryptoLocker ransomware will have a positive short-term impact, but they warn the threats could quickly re-emerge unless key steps are taken.
Law enforcement agencies worldwide took part in a coordinated operation to disrupt the Gameover Zeus botnet and seize computer servers crucial to the CryptoLocker ransomware. A Russian citizen has been indicted in connection with the crackdown.
The arrests of more than 90 individuals for their alleged involvement in the use of BlackShades malware is a sign of progress in the global fight against cybercrime, but some experts question whether the crackdown will serve as a fraud deterrent.
The indictment of nine alleged participants in a fraud scheme that involved infecting thousands of business computers with Zeus malware to steal millions of dollars shows that the malware remains a formidable ongoing threat.
A ransomware campaign has targeted millions of bank clients in the U.K., and experts warn of a worldwide surge in attacks. They say banking institutions have to be diligent about informing customers of the risk.
Russian authorities have reportedly arrested a man believed to be the author of the Blackhole exploit kit, widely used by cybercriminals to exploit vulnerabilities in Web browsers and other software to infect user computers with malware.
In light of growing threats and the increasing complexity of information technology, organizations must get everyone in the enterprise, especially top leaders, involved in assessing and managing information risk.
To mitigate the top threats for 2013, organizations need to understand the motivations of potential attackers so they can adequately defend their networks and systems. Experts describe risk management strategies for the year ahead.
