LockerGoga bug crashes ransomware before encrypting files

LockerGoga, the ransomware that hit Norsk Hydro and two US chemical companies over the past month, contains a bug in its code that may allow victims to “vaccinate” their PCs and crash the ransomware before it encrypts any local files.

The bug, discovered by security researchers at Alert Logic, is located in a LockerGoga subroutine that executes before the encryption process begins.

The subroutine is a basic scan of all files on the victim’s system, so the ransomware knows what files to encrypt and what to skip.

Alert Logic researchers say that if LockerGoga encounters an LNK (shortcut) file that contains an invalid path, the ransomware’s process crashes without performing the subsequent encryption.

“We have identified two conditions for the ‘.lnk’ file which would allow it to halt the ransomware in its tracks,” the Alert Logic team said. “The ‘.lnk’ file has been crafted to contain an invalid network path. The ‘.lnk’ file has no associated RPC endpoint.”

This trick may allow antivirus vendors to create what they call a “vaccine” –an app that creates malformed LNK files on users’ computers that prevent LockerGoga from running.

However, this bug only offers temporary relief. The LockerGoga ransomware group is also bound to found out about it and patch it in a future version.

Two new LockerGoga victims emerge

LockerGoga is one of today’s most dangerous ransomware strains. For the past three months, the ransomware has been deployed as part of highly targeted attacks against high-profile targets.

Hackers breach large companies, and after they gain access to internal networks, they deploy LockerGoga to as many workstations as they can for maximum damage.

French engineering firm Altran, Norwegian aluminum provider Norsk Hydro, and two US chemical firms, Hexion and Momentive, have reported infections so far –with news of the last two companies being hit emerging over the weekend.

While Norsk Hydro said it wouldn’t pay the ransom and instead restore infected computers from old backups, things haven’t been rosy at Momentive.

The company is said to have ordered new computers to replace the ones encrypted by LockerGoga, according to a Motherboard report citing an employee.

Security Tools Help Bring Dev and Security Teams Together

Published

on

Software development teams are increasingly focused on identifying and mitigating any issues as quickly and completely as possible. This relates not only to software quality but also software security. Different organizations are at different levels when it comes to having their development teams and security teams working in concert, but the simple fact remains that there are far more developers out there than security engineers.

Those factors are leading organizations to consider security tooling and automation to proactively discover and resolve any software security issues throughout the development process. In the recent report, “GigaOm Radar for Developer Security Tools,” Shea Stewart examines a roundup of security tools aimed at software development teams.

Stewart identified three critical criteria to bear in mind when evaluating developer security tools. These include:

  • Vendors providing tools to improve application security can and should also enhance an organization’s overall security posture.
  • The prevailing “shift-left” mindset doesn’t necessarily mean the responsibility for reducing risk should shift to development, but instead focusing on security earlier in the process and continuing to do so throughout the development process will reduce risk and the need for extensive rework.
  • Security throughout the entire software development lifecycle (SDLC) is critical for any organization focused on reducing risk.

Individual vendors have made varying levels of progress and innovation toward enhancing developer security. Following several acquisitions, Red Hat, Palo Alto Networks, and Rapid7 have all added tooling for developer security to their platforms. Stewart sees a couple of the smaller vendors like JFrog and Sonatype as continuing to innovate to remain ahead of the market.

Vendors delving into this category and moving deeper into “DevSecOps” all seem to be taking different approaches to their enhanced security tooling. While they are involving security in every aspect of the development process, some tend to be moving more quickly to match the pace of the SDLC. Others are trying to shore up existing platforms by adding functionality through acquisition. Both infrastructure and software developers are now sharing toolsets and processes, so these development security tools must account for the requirements of both groups.

While none of the 12 vendors evaluated in this report can provide comprehensive security throughout the entire SDLC, they all have their particular strengths and areas of focus. It is therefore incumbent upon the organization to fully and accurately assess its SDLC, involve the development and security teams, and match the unique requirements with the functionality provided by these tools. Even if it involves using more than one at different points throughout the process, focus on striking a balance between stringent security and simplifying the development process.

Key Criteria for Evaluating User and Entity Behavior Analytics (UEBA)

Published

on

Cybersecurity is a multidisciplinary practice that not only grows in complexity annually but evolves nearly as quickly. A survey of the security landscape today would reveal concerns ranging from the classic compromised servers to the relatively new DevSecOps practices aimed at securing the rapid deployment of new code and infrastructure. However, some things remain constant no matter how much change is introduced. While technology evolves and complexity varies, there is almost always a human component in
risks presented to an organization.

User Behavior Analysis (UBA) was designed to analyze the actions of users in an organization and attempt to identify normal and abnormal behaviors. From this analysis, malicious or risky behaviors can be detected. UBA solutions identify events that are not detectable using other methods because, unlike classic security tools (an IDS or SIEM for example), UBA does not simply pattern match or apply rule sets to data to identify security events. Instead, it looks for any and all deviations from baseline user activity.

As technology advanced and evolved, and the scope of what is connected to the network grew, the need to analyze entities other than users emerged. In response, entity analysis has been added to UBA to create UEBA or User and Entity Behavior Analysis. The strategy remains the same, but the scope of analysis has expanded to include entities involving things like daemons, processes, infrastructure, and so on.

How to Read this Report

This GigaOm report is one of a series of documents that helps IT organizations assess competing solutions in the context of well-defined features and criteria. For a fuller understanding consider reviewing the following reports:

Key Criteria report: A detailed market sector analysis that assesses the impact that key product features and criteria have on top-line solution characteristics—such as scalability, performance, and TCO—that drive purchase decisions.

GigaOm Radar report: A forward-looking analysis that plots the relative value and progression of vendor solutions along multiple axes based on strategy and execution. The Radar report includes a breakdown of each vendor’s offering in the sector.

Solution Profile: An in-depth vendor analysis that builds on the framework developed in the Key Criteria and Radar reports to assess a company’s engagement within a technology sector. This analysis includes forward-looking guidance around both strategy and product.
