Hackers Threaten to Leak D.C. Police Informants' Info If Ransom Is Not Paid

Hackers Threaten to Leak D.C. Police Informants' Info If Ransom Is Not Paid

April 27, 2021Ravie Lakshmanan
The Metropolitan Police Department (MPD) of the District of Columbia has become the latest high-profile government agency to fall victim to a ransomware attack. The Babuk Locker gang claimed in a post on the dark web that they had compromised the DC Police's networks and stolen 250 GB of unencrypted files. Screenshots shared by the group, and seen by The Hacker News, include various folders containing what appears to be investigation reports, arrests, disciplinary actions, and other intelligence briefings. Also called the DC Police, the MPD is the primary law enforcement agency for the District of Columbia in the U.S. The ransomware gang has given the department three days to heed to their ransom demand or risk leaking sensitive files that could expose police informants to criminal gangs. "Hello! Even an institution such as DC can be threatened, we have downloaded a sufficient amount of information from your internal networks, and we advise you to contact us as soon as p
Cybersecurity Webinar: Understanding the 2020 MITRE ATT&CK Results

Cybersecurity Webinar: Understanding the 2020 MITRE ATT&CK Results

April 27, 2021The Hacker News
The release of MITRE Engenuity's Carbanak+Fin7 ATT&CK evaluations every year is a benchmark for the cybersecurity industry. The organization's tests measure how well security vendors can detect and respond to threats and offers an independent metric for customers and security leaders to understand how well vendors perform on a variety of tasks. However, for the uninitiated, the results can be hard to decipher and contextualize properly. Unlike many benchmarks that compare participants in a competitive manner, MITRE's framework evaluates companies exclusively on how they respond to the tests. This means that customers must really know what they're looking for. A new webinar ( register here ) aims to provide some clarity on what to look for and how to interpret the results.  Cynet's new live webinar will dig a little deeper into the MITRE ATT&CK evaluation. The company's research team will break down how the evaluations work, what the results mean, an
Hackers Exploit 0-Day Gatekeeper Flaw to Attack macOS Computers

Hackers Exploit 0-Day Gatekeeper Flaw to Attack macOS Computers

April 27, 2021Ravie Lakshmanan
Security is only as strong as the weakest link. As further proof of this, Apple released an update to macOS operating systems to address an actively exploited zero-day vulnerability that could circumvent all security protections, thus permitting unapproved software to run on Macs. The macOS flaw, identified as  CVE-2021-30657 , was discovered and reported to Apple by security engineer Cedric Owens on March 25, 2021. "An unsigned, unnotarized, script-based proof of concept application [...] could trivially and reliably sidestep all of macOS's relevant security mechanisms (File Quarantine, Gatekeeper, and Notarization Requirements), even on a fully patched M1 macOS system," security researcher Patrick Wardle  explained  in a write-up. "Armed with such a capability macOS malware authors could (and are) returning to their proven methods of targeting and infecting macOS users." Apple's macOS comes with a feature called  Gatekeeper , which allows only  truste
FBI, CISA Uncover Tactics Employed by Russian Intelligence Hackers

FBI, CISA Uncover Tactics Employed by Russian Intelligence Hackers

April 27, 2021Ravie Lakshmanan
The U.S. Cybersecurity and Infrastructure Security Agency (CISA), Department of Homeland Security (DHS), and the Federal Bureau of Investigation (FBI) on Monday published a new joint advisory as part of their latest attempts to expose the tactics, techniques, and procedures (TTPs) adopted by the Russian Foreign Intelligence Service (SVR) in its attacks targeting the U.S and foreign entities. By employing "stealthy intrusion tradecraft within compromised networks," the intelligence agencies  said , "the SVR activity—which includes the recent  SolarWinds Orion supply chain compromise —primarily targets government networks, think tank and policy analysis organizations, and information technology companies and seeks to gather intelligence information." The cyber actor is also being tracked under different monikers, including Advanced Persistent Threat 29 (APT29), the Dukes, CozyBear, and Yttrium. The development comes as the U.S. sanctioned Russia and  formally pinn
Minnesota University Apologizes for Contributing Malicious Code to the Linux Project

Minnesota University Apologizes for Contributing Malicious Code to the Linux Project

April 26, 2021Ravie Lakshmanan
Researchers from the University of Minnesota apologized to the maintainers of Linux Kernel Project on Saturday for intentionally including vulnerabilities in the project's code, which led to the school being banned from contributing to the open-source project in the future. "While our goal was to improve the security of Linux, we now understand that it was hurtful to the community to make it a subject of our research, and to waste its effort reviewing these patches without its knowledge or permission," assistant professor Kangjie Lu, along with graduate students Qiushi Wu and Aditya Pakki,  said  in an email. "We did that because we knew we could not ask the maintainers of Linux for permission, or they would be on the lookout for the hypocrite patches," they added. The apology comes over a study into what's called "hypocrite commits," which was  published  earlier this February. The project aimed to deliberately add  use-after-free  vulnerabil

Apple AirDrop Bug Could Leak Your Personal Info to Anyone Nearby

April 26, 2021Ravie Lakshmanan
New research has uncovered privacy weaknesses in Apple's wireless file-sharing protocol that could result in the exposure of a user's contact information such as email addresses and phone numbers. "As an attacker, it is possible to learn the phone numbers and email addresses of AirDrop users – even as a complete stranger,"  said  a team of academics from the Technical University of Darmstadt, Germany. "All they require is a Wi-Fi-capable device and physical proximity to a target that initiates the discovery process by opening the sharing pane on an iOS or macOS device." AirDrop  is a proprietary ad hoc service present in Apple's iOS and macOS operating systems, allowing users to transfer files between devices by making use of close-range wireless communication. While this feature shows only receiver devices that are in users' contact lists by an authentication mechanism that compares an individual's phone number and email address with entrie

Emotet Malware Destroys Itself From All Infected Computers

Emotet Malware Destroys Itself From All Infected Computers

April 26, 2021Ravie Lakshmanan
Emotet, the notorious email-based Windows malware behind several botnet-driven spam campaigns and ransomware attacks, was automatically wiped from infected computers en masse following a European law enforcement operation. The development comes three months after a coordinated disruption of Emotet as part of " Operation Ladybird " to seize control of servers used to run and maintain the malware network. The orchestrated effort saw at least 700 servers associated with the botnet's infrastructure neutered from the inside, thus preventing further exploitation. Law enforcement authorities from the Netherlands, Germany, the U.S., U.K., France, Lithuania, Canada, and Ukraine were involved in the international action. Previously, the Dutch police, which seized two central servers located in the country, said it had deployed a software update to counter the threat posed by Emotet effectively. "All infected computer systems will automatically retrieve the update there, a
3.2 Billion Leaked Passwords Contain 1.5 Million Records with Government Emails

3.2 Billion Leaked Passwords Contain 1.5 Million Records with Government Emails

April 26, 2021Ravie Lakshmanan
A staggering number of 3.28 billion passwords linked to 2.18 billion unique email addresses were exposed in what's one of the largest data dumps of breached usernames and passwords. In addition, the leak includes 1,502,909 passwords associated with email addresses from government domains across the world, with the U.S. government alone taking up 625,505 of the exposed passwords, followed by the U.K (205,099), Australia (136,025), Brazil (68,535), and Canada (50,726). The findings come from an analysis of a massive 100GB data set called "COMB21" — aka Compilation of Many Breaches — that was published for free in an online cybercrime forum earlier this February by putting together data from multiple leaks in different companies and organizations that occurred over the years. It's worth noting that a leak doesn't imply a breach of public administration systems. The passwords are said to have been obtained via techniques such as password hash cracking after bein
