    Most victims of the Stegoloader Trojan, which has recently been making its rounds in the news, are observed to come from healthcare organizations in North America.  The malware known as TROJ_GATAK has been active since 2012 and uses steganography techniques to hide components in .PNG files. Looking at recent victims of the Stegoloader malware, we observed that majority of the infected machines counted for the last three months came from the United States (66.82%), followed by Chile (9.10%), Malaysia (3.32%), Norway ...

    Earlier we talked about the out-of-band update for Flash Player that was released by Adobe (identified as APSB15-14) that was released to fix CVE-2015-3113. This update raised the Flash Player version to 18.0.0.194. Our analysis of the current flaw reveals that the root cause of CVE-2015-3113 is similar to CVE-2015-3043. Both cause a buffer overflow within the Flash Player code. In fact, code targeting the previous exploit can also cause crashes in version 18.0.0.160 (the version immediately before this emergency update). Both vulnerabilities can be used to ...

    It doesn't take an advanced malware to disrupt a business operation. In fact, even a simple backdoor is enough to do it. Earlier this year the Trend Micro Forward-Looking Threat Research Team closely monitored the operations of two Nigerian cybercriminals -- identified through aliases Uche and Okiki -- who attacked small businesses from developing countries to steal information and intercept transactions with their targets' partners. All this was done through HawkEye, a simple backdoor that costs around $35. While the malware used is simple, the cybercriminal operation itself is not. ...

    Adobe may have already patched a Flash Player vulnerability last week, but several users—especially those in the US, Canada, and the UK —are still currently exposed and are at risk of getting infected with CryptoWall 3.0. The Magnitude Exploit Kit included an exploit, detected as SWF_EXPLOIT.MJTE, for the said vulnerability, allowing attackers to spread crypto-ransomware into their target systems. We first saw signs of this activity yesterday, June 15, through our monitoring of threat intelligence from the Trend Micro™ Smart Protection ...




    A critical Mac vulnerability was discovered by OS X security researcher Pedro Vilaca last week. According to his research, any attacker can disable the BIOS lock just by taking advantage of a flaw in Apple’s S3 sleep state (more known as 'standby mode') suspend-resume implementation. Once an attacker does this, he can install bootkit malware onto a Mac BIOS without the user’s knowledge. This is can be a major issue for Mac owners since the vulnerability gives attackers unfettered access to their device. Since a bootkit ...
