Latest Java zero-day exploit is linked to Bit9 hacker attack - stewartfortalwyneho

The attacks discovered dying week that exploited a antecedently unknown Java vulnerability were likely launched by the same attackers that previously targeted security firm Bit9 and its customers, according to researchers from antivirus vendor Symantec.

Security researchers from FireEye, who found the new Java attacks last week, said that the Java feat installs a remote access while of malware called McRAT.

The menace, which Symantec products detect as Trojan.Naid, connects back to a command-and-control (C&C) server using the 110.173.55.187 IP (Internet Protocol) address, Symantec researchers said Fri in a web log spot.

"Interestingly, a Dardan.Naid sample was also sign-language by the compromised Bit9 certificate discussed in the Bit9 security incident update and used in an attack on another company," they aforementioned. "This sample too used the backchannel communicating server IP address 110.173.55.187."

Certificate stolen

Last month, Bit9, a companion that sells security products using whitelisting engineering, announced that hackers stony-broke into one of its servers and misused one of the company's digital certificates to sign malware. That malware was then used in attacks against few U.S. organizations, the companionship aforesaid.

"In the subsequent attacks on the 3 target organizations, the attackers appeared to have already compromised specific Websites (a watering place manner attack, suchlike to what was recently reported by Facebook, Apple and Microsoft)," Bit9's CTO Ravage Sverdlove said in a blog post last Monday. "We believe the attackers inserted a malicious Java applet onto those sites that exploited a exposure in Java to deliver additional malicious files, including files signed by the compromised certificate."

One of those malicious files on-line posterior to Information science address "110.173.55.187" over port 80, the Bit9 CTO said. The IP is registered to an address in Hong Kong.

"The Trojan.Naid attackers have been extremely lasting and have shown their sophistication in duple attacks," the Symantec researchers same. "Their primary motivation has been industrial espionage on a variety of industry sectors."

Seek nada-day flaws

The attacks they set up ordinarily involve zero-day vulnerabilities. In 2022 they conducted a watering trap attack—an snipe where a internet site frequently visited by the intended targets is infected—that exploited a cypher-daytime vulnerability in Internet IE, the Symantec researchers said.

Oracle has yet to reveal its patching plans for this latest Java exposure. The next Java security update was scheduled for April, but the company power decide to put out an emergency update before then.

Security researchers receive advised users who don't need access to Web-based Java content to remove the Coffee plug-in from their browsers. The latest rendering of Java—Coffee 7 Update 15—provides an alternative through its control board to handicap the Java plug-ins or to force a confirmation prompt in front Java applets are allowed to black market inside the browser.
