Select Ukrainian government networks have remained infected with a malware called OfflRouter since 2015. Cisco Talos said its findings are based on an analysis of over 100 confidential documents that were infected with the VBA macro virus and uploaded to the VirusTotal malware scanning platform since 2018. More than 20 such documents have been uploaded since 2022. "The documents contained VBA code to drop and run an executable with the name 'ctrlpanel.exe,'" security researcher Vanja Svajcer  said . "The virus is still active in Ukraine and is causing potentially confidential documents to be uploaded to publicly accessible document repositories." A striking aspect of OfflRouter is its inability to spread via email, necessitating that it be propagated via other means, such as sharing documents and removable media, including USB memory sticks containing the infected documents. "It would require manual user intervention to send an infected document as...

Do you deal with MS Word files on the daily basis? If yes, then are you aware that even opening a simple doc file could compromise your system? It is a matter to think that the virus does not directly affect you, but it is you who let the virus carry out the attack by enabling deadly "Macros" to view the doc contents that are generally on eye-catching subjects like bank invoice. How Macros are Crippling your System? The concept of Macros dates back to 1990s. You must be familiar with this message: " Warning: This document contains macros. " A Macro is a series of commands and actions that help to automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Hackers are cleverly using this technique on the shade of social engineering by sending the malicious Macros through doc file or spreadsheet with an eye-catching subject in t...

After targeting Windows-based computers over the past few years, hackers are now shifting their interest to Macs as well. The emergence of the first macro-based Word document attack against Apple's macOS platform is the latest example to prove this. The concept of Macros dates back to 1990s. You might be familiar with the message that reads: " Warning: This document contains macros. " Macro is a series of commands and actions that help automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Until now, hackers were cleverly using this technique to target Windows. However, security researchers have now detected the first in-the-wild instance of hackers are making use of malicious macros in Word documents to install malware on Mac computers and steal your data – an old Windows technique. The hack tricks victims into opening infected W...

If just relying on the security tools of Microsoft Office 365 can protect you from cyber attacks, you are wrong. Variants of Cerber Ransomware are now targeting MS Office 365 email users with a massive zero-day attack that has the ability to bypass Office 365's built-in security tools. According to a report published by cloud security provider Avanan, the massive zero-day Cerber ransomware attack targeted Microsoft Office 365 users with spam or phishing emails carrying malicious file attachments. The Cerber ransomware is invoked via Macros. Yes, it's hard to believe but even in 2016, a single MS Office document could compromise your system by enabling ' Macros '. Locky and Dridex ransomware malware also made use of the malicious Macros to hijack systems. Over $22 Million were pilfered from the UK banks with the Dridex Malware that got triggered via a nasty macro virus. You can see a screenshot of the malicious document in the latest malware campaign belo...

Security researchers have discovered two separate malware campaigns, one of which is distributing the Ursnif data-stealing trojan and the GandCrab ransomware in the wild, whereas the second one is only infecting victims with Ursnif malware. Though both malware campaigns appear to be a work of two separate cybercriminal groups, we find many similarities in them. Both attacks start from phishing emails containing an attached Microsoft Word document embedded with malicious macros and then uses Powershell to deliver fileless malware. Ursnif is a data-stealing malware that typically steals sensitive information from compromised computers with an ability to harvest banking credentials, browsing activities, collect keystrokes, system and process information, and deploy additional backdoors. Discovered earlier last year, GandCrab is a widespread ransomware threat that, like every other ransomware in the market, encrypts files on an infected system and insists victims to pay a ransom ...

Hit by Jaff Ransomware? Don't pay the Ransom. You can unlock your files for Free! Kaspersky Labs has released an updated version 1.21.2.1 of its free ransomware decryption tool, RakhniDecryptor, which can now also decrypt files locked by the Jaff ransomware . Security researchers at Kaspersky Labs have discovered a weakness in the Jaff ransomware code that makes it possible for victims to unlock their Jaff-infected files for free. First identified last month, Jaff is relatively new ransomware that's being distributed with the help of ' Necurs botnet ' that currently controls over 6 million infected computers worldwide. Necurs botnet is the same botnet – army of compromised internet connected devices – that was used to distribute Dridex Banking Trojan and Locky ransomware , which also infects users' machines, encrypt files and then demand a ransom before unlocking them. Jaff ransomware (Trojan-Ransom.Win32.Jaff) attack is primarily carried out by sending ...

If you receive a mail masquerading as a company's invoice and containing a Microsoft Word file, think twice before clicking on it. Doing so could cripple your system and could lead to a catastrophic destruction. Hackers are believed to be carrying out social engineering hoaxes by adopting eye-catching subjects in the spam emails and compromised websites to lure the victims into installing a deadly ransomware, dubbed " Locky ," into their systems. So if you find .locky extension files on your network shares, Congratulations! You are infected and left with just two solutions: Rebuild your PC from scratch or Pay the ransom. Locky ransomware is spreading at the rate of 4000 new infections per hour , which means approximately 100,000 new infections per day . Microsoft MACROS are Back It is hard to digest the fact that, in this 2016, even a single MS Word document could compromise your system by enabling ' Macros .' This is where the poin...

A massive malicious email campaign that stems from the Necurs botnet is spreading a new ransomware at the rate of 5 million emails per hour and hitting computers across the globe. Dubbed "Jaff," the new file-encrypting ransomware is very similar to the infamous Locky ransomware in many ways, but it is demanding 1.79 Bitcoins (approx $3,150), which much higher than Locky, to unlock the encrypted files on an infected computer. According to security researchers at Forcepoint Security Lab, Jaff ransomware, written in C programming language, is being distributed with the help of Necurs botnet that currently controls over 6 million infected computers worldwide. Necurs botnet is sending emails to millions of users with an attached PDF document, which if clicked, opens up an embedded Word document with a malicious macro script to downloads and execute the Jaff ransomware, Malwarebytes says . Jaff is Spreading at the Rate of 5 Million per Hour The malicious email camp...
