The Ukrainian government on Monday warned of "massive cyberattacks" by Russia targeting critical infrastructure facilities located in the country and that of its allies. The attacks are said to be targeting the energy sector, the Main Directorate of Intelligence of the Ministry of Defense of Ukraine (GUR) said. "By the cyberattacks, the enemy will try to increase the effect of missile strikes on electricity supply facilities, primarily in the eastern and southern regions of Ukraine," the agency  said  in a brief advisory. GUR also cautioned of intensified distributed denial-of-service (DDoS) attacks aimed at the critical infrastructure of Ukraine's closest allies, chiefly Poland and the Baltic states of Estonia, Latvia, and Lithuania. It's not immediately clear what prompted the intelligence agency to issue the notice, but Ukraine has been at the receiving end of  disruptive and destructive cyberattacks  since the onset of the Russo-Ukrainian war earli

Cybercriminals are continuing to prey on users searching for cracked software by directing them to fraudulent websites hosting weaponized installers that deploy malware called  NullMixer  on compromised systems. "When a user extracts and executes NullMixer, it drops a number of malware files to the compromised machine," cybersecurity firm Kaspersky said in a Monday report. "It drops a wide variety of malicious binaries to infect the machine with, such as backdoors, bankers, downloaders, spyware, and many others." Besides siphoning users' credentials, address, credit card data, cryptocurrencies, and even Facebook and Amazon account session cookies, what makes NullMixer insidious is its ability to download dozens of trojans at once, significantly widening the scale of the infections. Attack chains typically start when a user attempts to download cracked software from one of the sites, which leads to a password-protected archive that contains an executable fil

As work ebbs with the typical end-of-year slowdown, now is a good time to review user roles and privileges and remove anyone who shouldn't have access as well as trim unnecessary permissions. In addition to saving some unnecessary license fees, a clean user inventory significantly enhances the security of your SaaS applications. From reducing risk to protecting against data leakage, here is how you can start the new year with a clean user list.  How Offboarded Users  Still  Have Access to Your Apps When employees leave a company, they trigger a series of changes to backend systems in their wake. First, they are removed from the company's identity provider (IdP), which kicks off an automated workflow that deactivates their email and removes access to all internal systems. When enterprises use an SSO (single sign-on), these former employees lose access to any online properties – including SaaS applications – that require SSO for login.  However, that doesn't mean that former employee

As many as 75 apps on Google Play and 10 on Apple App Store have been discovered engaging in ad fraud as part of an ongoing campaign that commenced in 2019. The latest iteration, dubbed  Scylla  by Online fraud-prevention firm HUMAN Security, follows similar attack waves in August 2019 and late 2020 that go by the codename Poseidon and Charybdis, respectively. Prior to their removal from the app storefronts, the apps had been collectively installed more than 13 million times. The original Poseidon operation comprised over 40 Android apps that were designed to display ads out of context or hidden from the view of the device user. Charybdis, on the other hand, was an improvement over the former by making use of code obfuscation tactics to target advertising platforms. Scylla presents the latest adaption of the scheme in that it expands beyond Android to make a foray into the iOS ecosystem for the first time, alongside relying on additional layers of code roundabout using the  All

The global cybersecurity market is flourishing. Experts at Gartner predict that the end-user spending for the information security and risk management market will grow from $172.5 billion in 2022 to $267.3 billion in 2026.  One big area of spending includes the art of putting cybersecurity defenses under pressure, commonly known as security testing. MarketsandMarkets forecasts the global penetration testing (pentesting) market size is expected to grow at a Compound Annual Growth Rate (CAGR) of 13.7% from 2022 to 2027. However, the costs and limitations involved in carrying out a penetration test are already hindering the market growth, and consequently, many cybersecurity professionals are making moves to find an alternative solution. Pentests aren't solving cybersecurity pain points Pentesting can serve specific and important purposes for businesses. For example, prospective customers may ask for the results of one as proof of compliance. However, for certain challenges, this

The infamous Lazarus Group has continued its pattern of leveraging unsolicited job opportunities to deploy malware targeting Apple's macOS operating system. In the latest variant of the campaign observed by cybersecurity company SentinelOne last week, decoy documents advertising positions for the Singapore-based cryptocurrency exchange firm Crypto[.]com have been used to mount the attacks. The latest disclosure builds on previous findings from Slovak cybersecurity firm ESET in August, which  delved  into a similar phony job posting for the Coinbase cryptocurrency exchange platform. Both these fake job advertisements are just the latest in a series of attacks dubbed  Operation In(ter)ception , which, in turn, is a constituent of a broader campaign tracked under the name  Operation Dream Job . Although the exact distribution vector for the malware remains unknown, it's suspected that potential targets are singled out via direct messages on the business networking site Linke

The Australian Federal Police (AFP) on Monday disclosed it's working to gather "crucial evidence" and that it's collaborating with overseas law enforcement authorities following the hack of telecom provider Optus. "Operation Hurricane has been launched to identify the criminals behind the alleged breach and to help shield Australians from identity fraud," the AFP  said  in a statement. The development comes after Optus, Australia's second-largest wireless carrier,  disclosed  on September 22, 2022, that it was a victim of a cyberattack. It claimed it "immediately shut down the attack" as soon as it came to light. The threat actor behind the breach also briefly released a sample of 10,200 records from the breach – putting those users at heightened risk of fraud – in addition to asking for $1 million as part of an extortion demand. The dataset has since been taken down, with the attacker also claiming to have deleted the only copy of the sto

At least three alleged hacktivist groups working in support of Russian interests are likely doing so in collaboration with state-sponsored cyber threat actors, according to Mandiant. The Google-owned threat intelligence and incident response firm  said  with moderate confidence that "moderators of the purported hacktivist Telegram channels 'XakNet Team,' 'Infoccentr,' and 'CyberArmyofRussia_Reborn' are coordinating their operations with Russian Main Intelligence Directorate (GRU)-sponsored cyber threat actors." Mandiant's assessment is based on evidence that the leakage of data stolen from Ukrainian organizations occurred within 24 hours of  malicious wiper incidents  undertaken by the Russian nation-state group tracked as  APT28  (aka Fancy Bear, Sofacy, or Strontium). To that end, four of the 16 data leaks from these groups coincided with  disk wiping malware attacks  by APT28 that involved the use of a strain dubbed  CaddyWiper . APT28 , a
