New Internet Explorer, Chrome zero-days highlight a growing market

Hackers are still using vulnerabilities in the seven-year-old Internet Explorer 11 browser to go after targets, even as Microsoft plans to sunset the program in less than a year, researchers at Google’s Threat Analysis Group reported Wednesday. The campaign largely targeted victims in Armenia. In April and June cybercriminals targeted Armenian users with the exploit, researchers found. “This exploit was delivered via an Office document rather than via the Internet Explorer browser [graphical user interface],” explained Shane Huntley, director of Google’s Threat Analysis Group. “Even if a user was to uninstall Internet Explorer, the exploit would still work.” Microsoft fixed the exploit in June. The same surveillance group also cashed in with two vulnerability in Chrome over the past several months. They sent the exploits via email with links posing as legitimate websites. The links sent users targets to attacker-controlled domains that fingerprinted a user’s device and allowed hackers to […] The post New Internet Explorer, Chrome zero-days highlight a growing market appeared first on CyberScoop.

An espionage campaign spread its wings from Myanmar to the Philippines, raising new questions

A cyberespionage campaign that spread through Myanmar last fall at first looked like many others of the genre: a handpicked set of targets affected by highly tailored break-in methods. After all, scattershot attacks historically are not only less likely to hit valuable victims, but they also equal a greater chance of being caught and halted before the hackers gather the information they want. Then something changed, according to the security firm Kaspersky. What began as a small campaign — ultimately affecting approximately 100 Myanmar victims that Kaspersky identified — leapfrogged to another country, the Philippines, where the victim count exploded to 1,400 and included some government entities. Kaspersky researchers on Wednesday detailed the extent of the campaign, and who they believe is behind it. But they remain unsure why it evolved the way it did, even if they have some informed guesses. The investigators attributed the infections to a group […] The post An espionage campaign spread its wings from Myanmar to the Philippines, raising new questions appeared first on CyberScoop.

CISA orders agencies to disable Microsoft Print Spooler in response to 'PrintNightmare' flaw

The Cybersecurity and Infrastructure Security Agency late Tuesday ordered federal agencies to disable the Microsoft Windows Print Spooler service because of an alarming flaw that could allow attackers to take over systems remotely. CISA, part of the Department of Homeland Security, gave agencies until midnight Wednesday to disable the service in response to the so-called “PrintNightmare” bug. Its “emergency directive” also ordered agencies to implement Microsoft security updates by July 20. The PrintNightmare issue has given Microsoft fits for weeks. It issued a patch last week that some security pros said didn’t work properly. On Tuesday, Microsoft issued another Print Spooler fix as part of its “Patch Tuesday” update, the latest of which also included answers for 13 “critical vulnerabilities” and four under active attack. “CISA has determined that this vulnerability poses an unacceptable risk to Federal Civilian Executive Branch agencies and requires emergency action,” CISA said in its PrintSpooler […] The post CISA orders agencies to disable Microsoft Print Spooler in response to 'PrintNightmare' flaw appeared first on CyberScoop.
