Did Someone at the Commerce Dept. Find a SolarWinds Backdoor in Aug. 2020?

April 16, 2021

On Aug. 13, 2020, someone uploaded a suspected malicious file to VirusTotal, a service that scans submitted files against more than five dozen antivirus and security products. Last month, Microsoft and FireEye identified that file as a newly-discovered fourth malware backdoor used in the sprawling SolarWinds supply chain hack. An analysis of the malicious file and other submissions by the same VirusTotal user suggest the account that initially flagged the backdoor as suspicious belongs to IT personnel at the National Telecommunications and Information Administration (NTIA), a division of the U.S. Commerce Department that handles telecommunications and Internet policy.

Chronicle: A Meteor Aimed At Planet Threat Intel?

January 24, 2018

Alphabet Inc., the parent company of Google, said today it is in the process of rolling out a new service designed to help companies more quickly make sense of and act on the mountains of threat data produced each day by cybersecurity tools.

Countless organizations rely on a hodgepodge of security software, hardware and services to find and detect cybersecurity intrusions before an incursion by malicious software or hackers has the chance to metastasize into a full-blown data breach.

Carbon Emissions: Oversharing Bug Puts Security Vendor Back in Spotlight

August 18, 2017

Last week, security firm DirectDefense came under fire for over-hyping claims that Cb Response, a cybersecurity product sold by competitor Carbon Black, was leaking proprietary from customers who use it. Carbon Black responded that the bug identified by its competitor was a feature, and that customers were amply cautioned in advance about the potential privacy risks of using the feature. Now Carbon Black is warning that an internal review has revealed a wholly separate bug in Cb Response that could in fact result in certain customers unintentionally sharing sensitive files.

Personalized Exploit Kit Targets Researchers

August 15, 2013

As documented time and again on this blog, cybercrooks are often sloppy or lazy enough to leave behind important clues about who and where they are. But from time to time, cheeky crooks will dream up a trap designed to look like they’re being sloppy when in fact they’re trying to trick security researchers into being sloppy and infecting their computers with malware.

Bit9 Breach Began in July 2012

February 20, 2013

Cyber espionage hackers who broke into security firm Bit9 initially breached the company’s defenses in July 2012, according to evidence being gathered by security experts investigating the incident. Bit9 remains reluctant to name customers that were impacted by the intrusion, but the custom-made malicious software used in the attack was deployed last year in highly targeted attacks against U.S. Defense contractors.

Adware Stages Comeback Via Browser Extensions

May 21, 2012

The Wikimedia Foundation last week warned that readers who are seeing ads on Wikipedia articles are likely using a Web browser that has been infected with malware. The warning points to an apparent resurgence in adware and spyware that is being delivered via cleverly disguised browser extensions and plugins that are bundled with other software or foisted in social engineering schemes.

NetworkSolutions Sites Hacked By Wicked Widget

August 16, 2010

Hundreds of thousands of Web sites parked at NetworkSolutions.com have been serving up malicious software, thanks to a tainted widget embedded in the pages, a security company warned Saturday.

Web application security vendor Armorize said it found the mass infection while responding to a complaint by one of its largest customers. Armorize said it traced the problem back to the “Small Business Success Index” widget, an application that Network Solutions makes available to site owners through its GrowSmartBusiness.com blog.

Virus Scanners for Virus Authors, Part II

April 5, 2010

The very first entry I posted at Krebs on Security, Virus Scanners for Virus Authors, introduced readers to two services that let virus writers upload their creations to see how well they are detected by various commercial anti-virus scanners on the market. In this follow-up post, I’ll take you inside of a pair of similar services that allow customers to periodically scan a malware sample ad receive alerts via instant message or e-mail when a new anti-virus product begins to detect the submission as malicious.
