Cybersecurity researchers from Facebook today formally linked the activities of a Vietnamese threat actor to an IT company in the country after the group was caught abusing its platform to hack into people's accounts and distribute malware. Tracked as  APT32  (or Bismuth, OceanLotus, and Cobalt Kitty), the state-aligned operatives affiliated with the Vietnam government have been known for orchestrating sophisticated  espionage campaigns  at least since 2012 with the goal of furthering the country's strategic interests. "Our investigation linked this activity to CyberOne Group, an IT company in Vietnam (also known as CyberOne Security, CyberOne Technologies, Hành Tinh Company Limited, Planet and Diacauso)," Facebook's Head of Security Policy, Nathaniel Gleicher, and Cyber Threat Intelligence Manager, Mike Dvilyanski,  said . Exact evidence trail leading Facebook to attribute the hacking activity to CyberOne Group was not disclosed, but according to a descrip...

Cisco has once again fixed four  previously disclosed critical bugs  in its Jabber video conferencing and messaging app that were inadequately addressed, leaving its users susceptible to remote attacks. The vulnerabilities, if successfully exploited, could allow an authenticated, remote attacker to execute arbitrary code on target systems by sending specially-crafted chat messages in group conversations or specific individuals. They were reported to the networking equipment maker on September 25 by Watchcom , three weeks after the Norwegian cybersecurity firm publicly disclosed multiple security shortcomings in Jabber that were found during a penetration test for a client in June. The new flaws, which were uncovered after one of its clients requested a verification audit of the patch, affects all currently supported versions of the Cisco Jabber client (12.1 - 12.9). "Three of the four vulnerabilities Watchcom  disclosed in September  have not been sufficiently...

Critical flaws in a core networking library powering Valve's online gaming functionality could have allowed malicious actors to remotely crash games and even take control over affected third-party game servers. "An attacker could remotely crash an opponent's game client to force a win or even perform a 'nuclear rage quit' and crash the Valve game server to end the game completely," Check Point Research's Eyal Itkin noted in an analysis published today. "Potentially even more damaging, attackers could remotely take over third-party developer game servers to execute arbitrary code." Valve is a popular US-based video game developer and publisher behind the game software distribution platform Steam and several titles such as Half-Life, Counter-Strike, Portal, Day of Defeat, Team Fortress, Left 4 Dead, and Dota. The four flaws (CVE-2020-6016 through CVE-2020-6019) were uncovered in Valve's Game Networking Sockets ( GNS ) or Steam Sockets libr...

The US Federal Trade Commission and a coalition of 48 state attorneys general on Wednesday filed a pair of sweeping antitrust suits against Facebook, alleging that the company abused its power in the marketplace to neutralize competitors through its acquisitions of Instagram and WhatsApp and depriving users of better privacy-friendly alternatives. "Facebook has engaged in a systematic strategy — including its 2012 acquisition of up-and-coming rival Instagram, its 2014 acquisition of the mobile messaging app WhatsApp, and the imposition of anti-competitive conditions on software developers — to eliminate threats to its monopoly," the FTC  said  in its complaint. A  separate lawsuit  filed by New York Attorney General Letitia James also claimed that in illegally acquiring competitors in a predatory manner, the social media company stripped users of the benefits of competition, limited consumer choices, and their access to rivals with better privacy practices. Spec...

A Russian threat actor known for its malware campaigns has reappeared in the threat landscape with yet another attack leveraging COVID-19 as phishing lures, once again indicating how adversaries are adept at repurposing the current world events to their advantage. Linking the operation to a sub-group of APT28 (aka Sofacy, Sednit, Fancy Bear, or STRONTIUM), cybersecurity firm Intezer said the pandemic-themed phishing emails were employed to deliver the Go version of Zebrocy (or Zekapab) malware. The cybersecurity firm told The Hacker News that the campaigns were observed late last month. Zebrocy is delivered primarily via phishing attacks that contain decoy Microsoft Office documents with macros as well as executable file attachments. First spotted in the wild in 2015 , the operators behind the malware have been found to overlap with GreyEnergy , a threat group believed to be the successor of BlackEnergy aka Sandworm , suggesting its role as a sub-group with links to Sofacy and ...

Cybersecurity researchers disclosed a dozen new flaws in multiple widely-used embedded TCP/IP stacks impacting millions of devices ranging from networking equipment and medical devices to industrial control systems that could be exploited by an attacker to take control of a vulnerable system. Collectively called " AMNESIA:33 " by Forescout researchers, it is a set of 33 vulnerabilities that impact four open-source TCP/IP protocol stacks — uIP, FNET, picoTCP, and Nut/Net — that are commonly used in Internet-of-Things (IoT) and embedded devices. As a consequence of improper memory management,  successful exploitation  of these flaws could cause memory corruption, allowing attackers to compromise devices, execute malicious code, perform denial-of-service (DoS) attacks, steal sensitive information, and even poison DNS cache. In the real world, these attacks could play out in various ways: disrupting the functioning of a power station to result in a blackout or taking smoke a...
