Russian state-sponsored actors are continuing to strike Ukrainian entities with information-stealing malware as part of what's suspected to be an espionage operation. Symantec, a division of Broadcom Software,  attributed  the malicious campaign to a threat actor tracked  Shuckworm , also known as  Actinium ,  Armageddon , Gamaredon, Primitive Bear, and Trident Ursa. The findings have been  corroborated  by the Computer Emergency Response Team of Ukraine (CERT-UA). The threat actor, active since at least 2013, is known for explicitly singling out public and private entities in Ukraine. The attacks have since ratcheted up in the wake of Russia's military invasion in late 2022. The latest set of attacks are said to have commenced on July 15, 2022, and ongoing as recently as August 8, with the infection chains leveraging phishing emails disguised as newsletters and combat orders, ultimately leading to the deployment of a PowerShell stealer malware dubbed  GammaLoad.PS1_v2 .

Popular end-to-end encrypted messaging service Signal on Monday disclosed the cyberattack aimed at Twilio earlier this month may have exposed the phone numbers of roughly 1,900 users. "For about 1,900 users, an attacker could have attempted to re-register their number to another device or learned that their number was registered to Signal," the company  said . "All users can rest assured that their message history, contact lists, profile information, whom they'd blocked, and other personal data remain private and secure and were not affected." Signal, which uses Twilio to send SMS verification codes to users registering with the app, said it's in the process of alerting the affected users directly and prompting them to re-register the service on their devices. The development comes less than a week after Twilio  revealed  that data associated with about 125 customer accounts were accessed by malicious actors through a phishing attack that duped the comp

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Credential theft is clearly still a problem. Even after years of warnings, changing password requirements, and multiple forms of authentication,  password  stealing remains a top attack method used by cyber criminals. The latest  report  from the Ponemon Institute shares that 54% of security incidents were caused by credential theft, followed by ransomware and DDoS attacks. 59% of organizations aren't revoking credentials that are no longer needed, meaning passwords can go unattended and dormant like a sitting duck (similar to what happened with Colonial Pipeline). And  Verizon's Data Breach Investigations Report  cites that nearly 50% of all data breaches were caused by stolen credentials. The stats don't lie. Cybercriminals are advancing, there's no doubt, but if there's an option to take the path of least resistance, they'll take it. Too often, that means compromising passwords and exploiting vulnerable access points.  Credential Theft and Critical Access

The SOVA Android banking trojan is continuing to be actively developed with upgraded capabilities to target no less than 200 mobile applications, including banking apps and crypto exchanges and wallets, up from 90 apps when it started out. That's according to the latest findings from Italian cybersecurity firm Cleafy, which found newer versions of the malware sporting functionality to intercept two-factor authentication (2FA) codes, steal cookies, and expand its targeting to cover Australia, Brazil, China, India, the Philippines, and the U.K. SOVA, meaning Owl in Russian, came to light in  September 2021  when it was observed striking financial and shopping apps from the U.S. and Spain for harvesting credentials through overlay attacks by taking advantage of Android's Accessibility services. In less than a year, the trojan has also acted as a foundation for another Android malware called  MaliBot  that's designed to target online banking and cryptocurrency wallet custo

A now-removed rogue package pushed to the official third-party software repository for Python has been found to deploy cryptominers on Linux systems. The module, named " secretslib " and  downloaded 93 times  prior to its deletion, was released to the Python Package Index (PyPI) on August 6, 2022 and is described as "secrets matching and verification made easy." "On a closer inspection though, the package covertly runs cryptominers on your Linux machine in-memory (directly from your RAM), a technique largely employed by fileless malware and crypters," Sonatype researcher Ax Sharma  disclosed  in a report last week. It achieves this by executing a Linux executable file retrieved from a remote server post installation, whose main task is to drop an  ELF  file (" memfd ") directly in memory that functions as a Monero cryptominer, after which it gets deleted by the "secretslib" package. "The malicious activity leaves little to n

Dutch authorities on Friday announced the arrest of a software developer in Amsterdam who is alleged to be working for Tornado Cash, days after the U.S. sanctioned the decentralized crypto mixing service. The 29-year-old individual is "suspected of involvement in concealing criminal financial flows and facilitating money laundering" through the service, the Dutch Fiscal Information and Investigation Service (FIOD)  said  in a statement. Although FIOD didn't reveal the name of the Tornado Cash engineer, The Block  identified  him as Alexey Pertsev, citing confirmation from his wife. "My husband didn't do anything illegal," she was quoted as saying. FIOD also alleged that "Tornado Cash has been used to conceal large-scale criminal money flows, including from (online) thefts of cryptocurrencies (so-called crypto hacks and scams)." The agency, which initiated an investigation into Tornado Cash in June 2022, further hinted it may make more arrests

A pair of reports from cybersecurity firms  SEKOIA  and  Trend Micro  sheds light on a new campaign undertaken by a Chinese threat actor named Lucky Mouse that involves leveraging a trojanized version of a cross-platform messaging app to backdoor systems. Infection chains leverage a chat application called MiMi, with its installer files compromised to download and install HyperBro samples for the Windows operating system and rshell artifacts for Linux and macOS. As many as 13 different entities located in Taiwan and the Philippines have been at the receiving end of the attacks, eight of whom have been hit with rshell. The first victim of rshell was reported in mid-July 2021. Lucky Mouse, also called  APT27 , Bronze Union, Emissary Panda, and Iron Tiger, is known to be active since 2013 and has a history of gaining access to targeted networks in pursuit of its political and military intelligence-collection objectives aligned with China.
