In a first-of-its-kind coordinated action, the U.K. and U.S. governments on Thursday levied sanctions against seven Russian nationals for their affiliation to the TrickBot, Ryuk, and Conti cybercrime operation. The individuals  designated  under sanctions are Vitaly Kovalev (aka Alex Konor, Bentley, or Bergen), Maksim Mikhailov (aka Baget), Valentin Karyagin (aka Globus), Mikhail Iskritskiy (aka Tropa), Dmitry Pleshevskiy (aka Iseldor), Ivan Vakhromeyev (aka Mushroom), and Valery Sedletski (aka Strix). "Current members of the TrickBot group are associated with Russian Intelligence Services," the U.S. Treasury Department  noted . "The TrickBot group's preparations in 2020 aligned them to Russian state objectives and targeting previously conducted by Russian Intelligence Services." TrickBot, which is attributed to a threat actor named ITG23, Gold Blackburn, and Wizard Spider, emerged in 2016 as a derivative of the Dyre banking trojan and evolved into a  highly...

Popular social news aggregation platform Reddit has disclosed that it was the victim of a security incident that enabled unidentified threat actors to gain unauthorized access to internal documents, code, and some unspecified business systems. The company blamed it on a "sophisticated and highly-targeted phishing attack" that took place on February 5, 2023, aimed at its employees. The attack entailed sending out "plausible-sounding prompts" that redirected to a website masquerading as Reddit's intranet portal in an attempt to steal credentials and two-factor authentication (2FA) tokens. A single employee's credentials is said to have been phished in this manner, enabling the threat actor to access Reddit's internal systems. The affected employee self-reported the hack, it further added. The company, however, stressed that there is no evidence to suggest that its production systems were breached or that users' non-public data had been compromise...

A set of 38 security vulnerabilities has been uncovered in wireless industrial internet of things (IIoT) devices from four different vendors that could pose a significant attack surface for threat actors looking to exploit operational technology (OT) environments. "Threat actors can exploit vulnerabilities in Wireless IIoT devices to gain initial access to internal OT networks," Israeli industrial cybersecurity company Otorio  said . "They can use these vulnerabilities to bypass security layers and infiltrate target networks, putting critical infrastructure at risk or interrupting manufacturing." The flaws, in a nutshell, offer a remote entry point for attack, enabling unauthenticated adversaries to gain a foothold and subsequently use it as leverage to spread to other hosts, thereby causing serious damage. Some of the identified shortcomings could be chained to give an external actor direct access to thousands of internal OT networks over the internet, security...

Have you ever stopped to think about the potential consequences of a cyberattack on your organization? It's getting more intense and destructive every day, and organizations are feeling the heat. That's why more and more businesses are turning to  cyber insurance  to find some much-needed peace of mind. Imagine, in the unfortunate event of a successful security breach or ransomware attack, the right policy can help minimize liability and contain losses. However, skyrocketing claims in 2020 sent shockwaves through the insurance industry, forcing insurance providers to reinvent the criteria for acquiring or renewing cyber insurance. As a result, businesses are now navigating a dramatically altered terrain where they must prove their ability to defend against ransomware attacks. This includes implementing a wide range of robust security measures, particularly around identity protection requirements such as MFA coverage and service account protection. The new identity protecti...

A previously unknown threat actor dubbed  NewsPenguin  has been linked to a phishing campaign targeting Pakistani entities by leveraging the upcoming international maritime expo as a lure. "The attacker sent out targeted phishing emails with a weaponized document attached that purports to be an exhibitor manual for PIMEC-23," the BlackBerry Research and Intelligence Team said . PIMEC , short for Pakistan International Maritime Expo and Conference, is an  initiative  of the Pakistan Navy and is organized by the Ministry of Maritime Affairs with an aim to "jump start development in the maritime sector." It's scheduled to be held from February 10-12, 2023. The Canadian cybersecurity company said the attacks are designed to target marine-related entities and the event's visitors by tricking the message recipients into opening the seemingly harmless Microsoft Word document. Once the document is launched and macros are enabled, a method called  remote templa...

A single ransomware attack on a New Zealand managed service provider (MSP) disrupted several of its clients' business operations overnight, most belonging to the healthcare sector. According to the country's privacy commissioner, " a cyber security incident involving a ransomware attack " in late November upended the daily operations of New Zealand's health ministry when it prevented the staff from accessing thousands of medical records. The Ministry of Justice, six health regulatory authorities, a health insurer, and a handful of other businesses also number among those affected by second-hand damage from the attack. There are ways to  recover from a ransomware attack , but the damage often extends into that attacked organization's customers and vendors.  The targeted MSP in this incident is Mercury IT, a business based in Australia. Te Whatu Ora, the New Zealand health ministry, was unable to access at least 14,000 medical records because of the outage at ...

The Gootkit malware is prominently going after healthcare and finance organizations in the U.S., U.K., and Australia, according to new findings from Cybereason. The cybersecurity firm said it investigated a Gootkit incident in December 2022 that adopted a new method of deployment, with the actors abusing the foothold to deliver  Cobalt Strike  and  SystemBC  for post-exploitation. "The threat actor displayed fast-moving behaviors, quickly heading to control the network it infected, and getting elevated privileges in less than four hours," Cybereason  said  in an analysis published February 8, 2023. Gootkit, also called Gootloader, is exclusively attributed to a threat actor tracked by Mandiant as UNC2565. Starting its life in 2014 as a banking trojan, the malware has since morphed into a loader capable of delivering next-stage payloads. The shift in tactics was  first uncovered  by Sophos in March 2021. Gootloader takes the form of heavily-o...

The OpenSSL Project has released fixes to address several security flaws, including a high-severity bug in the open source encryption toolkit that could potentially expose users to malicious attacks. Tracked as  CVE-2023-0286 , the issue relates to a case of type confusion that may permit an adversary to "read memory contents or enact a denial-of-service," the maintainers said in an advisory. The vulnerability is rooted in the way the  popular cryptographic library  handles X.509 certificates, and is likely to impact only those applications that have a custom implementation for retrieving a certificate revocation list ( CRL ) over a network. "In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature," OpenSSL  said . "If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon."...

The U.S. National Institute of Standards and Technology (NIST) has announced that a family of authenticated encryption and hashing algorithms known as Ascon will be standardized for  lightweight cryptography  applications. "The chosen algorithms are designed to protect information created and transmitted by the Internet of Things (IoT), including its myriad tiny sensors and actuators," NIST  said . "They are also designed for other miniature technologies such as implanted medical devices, stress detectors inside roads and bridges, and keyless entry fobs for vehicles." Put differently, the idea is to adopt security protections via lightweight cryptography in devices that have a "limited amount of electronic resources." That said, NIST still recommends the Advanced Encryption Standard ( AES ) and SHA-256 for general use. Ascon is  credited  to a team of cryptographers from the Graz University of Technology, Infineon Technologies, Lamarr Security Researc...
