  • CVE-2018-3211: Java Usage Tracker Local Elevation of Privilege on Windows -

    We found design flaw/weakness in Java Usage Tracker that can enable hackers to create arbitrary files, inject attacker-specified parameters, and elevate local privileges. In turn, these can be chained and used to escalate privileges in order to access resources in affected systems that are normally protected or restricted to other applications or users.

    We’ve worked with Oracle through our Zero Day Initiative to patch this flaw, and this has been fixed via Oracle’s October patch update. Users and businesses are accordingly urged to patch and update their version of Java.

    In this blog post, we will delve into how this flaw works on Windows — how Java Usage Tracker works and defining the conditions that enabled the exploit.

  • Phishing Campaign uses Hijacked Emails to Deliver URSNIF by Replying to Ongoing Threads -

    A spam campaign we observed in September indicates attackers are angling towards a more sophisticated form of phishing. The campaign uses hijacked email accounts to deliver URSNIF as part of or as a response to an existing email thread.

  • New CVE-2018-8373 Exploit Spotted -

    On September 18, 2018, more than a month after we published a blog revealing the details of a use-after-free (UAF) vulnerability CVE-2018-8373 that affects the VBScript engine in newer Windows versions, we spotted another exploit that uses the same vulnerability.  It's important to note that this exploit doesn't work on systems with updated Internet Explorer versions.

  • September Patch Tuesday: Windows Fixes ALPC Elevation of Privilege, Remote Code Execution Vulnerabilities -

    September’s Patch Tuesday provides a security patch for CVE-2018-8440, an elevation of privilege vulnerability that occurs when Windows incorrectly handles calls to the Advanced Local Procedure Call (ALPC) interface. This bug allows threat actors to run code with administrative privileges, install programs, or even create new accounts with full user rights. This bug’s source code has been publicly disclosed as of August 27 via Twitter and has been seen actively used in malicious campaigns as early as September 5.

  • A Closer Look at the Locky Poser, PyLocky Ransomware -

    While ransomware has noticeably plateaued in today’s threat landscape, it’s still a cybercriminal staple. In fact, it saw a slight increase in activity in the first half of 2018, keeping pace by being fine-tuned to evade security solutions, or in the case of PyLocky (detected by Trend Micro as RANSOM_PYLOCKY.A), imitate established ransomware families and ride on their notoriety.

    In late July and throughout August, we observed waves of spam email delivering the PyLocky ransomware. Although it tries to pass off as Locky in its ransom note, PyLocky is unrelated to Locky. PyLocky is written in Python, a popular scripting language; and packaged with PyInstaller, a tool used to package Python-based programs as standalone executables.

  • Stolen Data from Chinese Hotel Chain and Other Illicit Products Sold in Deep Web Forum -

    We uncovered personally identifiable information (PII) stolen from a China-based hotel chain being sold on a deep web forum we were monitoring. Further analysis revealed that the stolen data was not only the PII of Chinese customers, but also included the hotel chain’s customers from Western and East Asian countries. The sample data we saw was unencrypted (in plaintext), some of which were in CSV, SQL, and TXT dumps.

    We believe this stolen data is related to the data breach (reported on August 29) that exposed up to 130 million PII. The news that reported the data breach matched with an advertisement we saw in the dark web selling the stolen data for eight bitcoins (equivalent to more than US$58,000 as of September 5, 2018).

  • The Urpage Connection to Bahamut, Confucius and Patchwork -

    In the process of monitoring changes in the threat landscape, we get a clearer insight into the way threat actors work behind the schemes. In this case we dig deeper into the possible connection between cyberattacks by focusing on the similarities an unnamed threat actor shares with Confucius, Patchwork, and another threat actor called Bahamut. For the sake of this report, we will call this unnamed threat actor “Urpage.”

  • IQY and PowerShell Abused by Spam Campaign to Infect Users in Japan with BEBLOH and URSNIF -

    Trend Micro recently saw increased abuse of the internet query file IQY, similar to the activity detected in June from a Necurs-distributed spam wave that delivered the FlawedAmmyy RAT. It appears cybercriminals are taking advantage of the simple structure of IQY files because they can be used to evade structure-based detection methods.

    Our latest observation found the Cutwail botnet distributing spam mails abusing IQY files. The spam campaign specifically targets users in Japan, delivering either the BEBLOH (detected by Trend Micro as TSPY_BEBLOH.YMNPV) or URSNIF (TSPY_URSNIF.TIBAIDO) malware. The spam mails attempt to trick users into clicking the attachment using conventional social engineering baits such as "payment," "photos sent," “photos attached,” and "please confirm," among others. The campaign’s activity was detected on August 6, 2018, and has managed to distribute approximately 500,000 spam mails. The spam distribution has since died down on August 9.
