An updated version of a botnet malware called  KmsdBot  is now targeting Internet of Things (IoT) devices, simultaneously branching out its capabilities and the attack surface. "The binary now includes support for  Telnet scanning  and support for more CPU architectures," Akamai security researcher Larry W. Cashdollar  said  in an analysis published this month. The latest iteration, observed since July 16, 2023, comes months after it emerged that the botnet is being offered as a  DDoS-for-hire service  to other threat actors. The fact that it's being actively maintained indicates its effectiveness in real-world attacks. KmsdBot was  first documented  by the web infrastructure and security company in November 2022. It's mainly employed to target private gaming servers and cloud hosting providers, although it has since set its eyes on some Romanian government and Spanish educational sites. The malware is designed to scan random IP ad...

The leak of the  LockBit 3.0 ransomware  builder last year has led to threat actors abusing the tool to spawn new variants. Russian cybersecurity company Kaspersky said it detected a ransomware intrusion that deployed a version of LockBit but with a markedly different ransom demand procedure. "The attacker behind this incident decided to use a different ransom note with a headline related to a previously unknown group, called NATIONAL HAZARD AGENCY," security researchers Eduardo Ovalle and Francesco Figurelli  said . The revamped ransom note directly specified the amount to be paid to obtain the decryption keys, and directed communications to a Tox service and email, unlike the LockBit group, which doesn't mention the amount and uses its own communication and negotiation platform. NATIONAL HAZARD AGENCY is far from the only cybercrime gang to use the leaked LockBit 3.0 builder. Some of the other threat actors known to leverage it include  Bl00dy and Buhti . Kas...

Risk and financial advisory solutions provider Kroll on Friday disclosed that one of its employees fell victim to a "highly sophisticated" SIM swapping attack. The incident, which took place on August 19, 2023, targeted the employee's T-Mobile account, the company said. "Specifically, T-Mobile, without any authority from or contact with Kroll or its employee, transferred that employee's phone number to the threat actor's phone at their request," it  said  in an advisory. This enabled the unidentified actor to gain access to certain files containing personal information of bankruptcy claimants in the matters of BlockFi , FTX , and Genesis. SIM swapping (aka SIM splitting or simjacking), while generally a benign process, could be exploited by threat actors to fraudulently activate a SIM card under their control with a victim's phone number. This makes it possible to intercept SMS messages and voice calls and receive MFA-related messages that cont...

Two U.K. teenagers have been convicted by a jury in London for being part of the notorious LAPSUS$ (aka Slippy Spider) transnational gang and for orchestrating a series of brazen, high-profile hacks against major tech firms and demanding a ransom in exchange for not leaking the stolen information. This includes Arion Kurtaj (aka White, Breachbase, WhiteDoxbin, and TeaPotUberHacker), an 18-year-old from Oxford, and an unnamed minor, who began collaborating in July 2021 after having met online, BBC  reported  this week. Both the defendants were initially arrested and released under investigation in January 2022, only to be  re-arrested and charged  by the City of London Police in April 2022. Kurtaj was subsequently granted bail and moved to a hotel in Bicester after he was doxxed in an online cybercrime forum. He, however, continued his hacking spree, targeting companies like  Uber ,  Revolut , and  Rockstar Games , as a result of which he was  ...
