Cybersecurity researchers have discovered a new information stealer dubbed SYS01stealer targeting critical government infrastructure employees, manufacturing companies, and other sectors. "The threat actors behind the campaign are targeting Facebook business accounts by using Google ads and fake Facebook profiles that promote things like games, adult content, and cracked software, etc. to lure victims into downloading a malicious file," Morphisec said in a report shared with The Hacker News.
Deep fakes are expected to become a more prominent attack vector. Audio deep fakes are created by taking audio files, allocating annotations to the sounds, training an ML model based on the annotations to associate sounds with text and then generating a new audio file.
"These vulnerabilities can be triggered from user-mode applications by sending malicious commands to a TPM 2.0 whose firmware is based on an affected TCG reference implementation," the Trusted Computing Group said in an advisory. Large tech vendors, organizations using enterprise computers, servers, IoT devices, and embedded systems that include a TPM can be impacted by the flaws, Quarkslab noted, adding they "Could affect billions of devices."
Threat watchers have spotted new cybersecurity exploits illustrating the protean nature of hacks as malware groups adapt and find new opportunities in dynamic link libraries and common vulnerabilities and exposures. Figure A. Zugec said Bitdefender has seen a large spike in the use of this tactic "Due to the fact that DLL sideloading allows the threat actors to stay hidden. Many endpoint security solutions are going to see that the DLL files are executable, signed, for example, by Microsoft or by any big name company known to be trusted. But, this trusted library is going to load malicious code."
The U.S. Cybersecurity and Infrastructure Security Agency is urging organizations and individuals to increase their cyber vigilance, as Russia's military invasion of Ukraine officially enters one year. "CISA assesses that the United States and European nations may experience disruptive and defacement attacks against websites in an attempt to sow chaos and societal discord on February 24, 2023, the anniversary of Russia's 2022 invasion of Ukraine," the agency said.
Amid uncertain economic conditions, the technology sector has been a hot topic of discussion in recent months due to the mass amounts of layoffs across the industry. In this Help Net Security video, Nick Tausek, Lead Security Automation Architect at Swimlane, talks about how with the stress, anxiety, frustration, and unknown of what lies ahead for these suddenly unemployed workers, organizations need to prepare themselves for insider threats.
Shipping companies and medical laboratories in Asia have been the subject of a suspected espionage campaign carried out by a never-before-seen threat actor dubbed Hydrochasma. The standout aspects of the campaign is the absence of data exfiltration and custom malware, with the threat actor employing open source tools for intelligence gathering.
Sponsored Post The global impact of cyber threats on businesses, governments, organisations and individuals around the world is ramping up exponentially, with experts warning that danger is set to dramatically worsen in coming months and years. Thankfully, it is apparent that investment is being increased in cyber defence.
An open source command-and-control framework known as Havoc is being adopted by threat actors as an alternative to other well-known legitimate toolkits like Cobalt Strike, Sliver, and Brute Ratel. Cybersecurity firm Zscaler said it observed a new campaign in the beginning of January 2023 targeting an unnamed government organization that utilized Havoc.
Enterprises looking to modernize their APIs are increasingly switching from the REST architecture to the open-source data query and manipulation language GraphQL. While the transition makes sense - GraphQL is more flexible, scalable, and easier for developers to use - attackers are also seeing new opportunities for mischief. Those finding themselves within the developer led GraphQL movement must understand the current threats facing them and recognize that GraphQL increases their own security responsibilities.
