Bitdefender vs Norton vs McAfee 2026: 2 Win Gold, 1 Bronze

In 2026, Bitdefender, Norton 360, and McAfee each achieved a perfect score of 18 out of 18 in AV-TEST’s April evaluation. Bitdefender excels in protection technology and has the lightest footprint among paid tiers. Norton 360 offers an unlimited VPN, substantial cloud backup, and LifeLock identity theft protection, achieving the best real-world protection score in 2025. McAfee is strong in identity protection and unlimited-device pricing but falls short in core malware engine performance. Bitdefender is noted for its advanced threat detection and has a low entry price of .99 for its Antivirus Plus. Norton 360 includes an unlimited VPN and up to 250 GB cloud backup, while McAfee+ Ultimate provides identity theft coverage and three-bureau credit monitoring. All three products received perfect scores in AV-TEST’s April evaluation, but independent lab results from AV-Comparatives showed Norton and Bitdefender as Top-Rated Products, while McAfee did not achieve this status. The specifications comparison reveals that Bitdefender supports up to 25 devices, Norton 360 offers unlimited devices, and McAfee also supports unlimited devices. Bitdefender employs Advanced Threat Defense, Norton uses SONAR and Intrusion Prevention, and McAfee utilizes Real Protect. Norton and McAfee received AV-Comparatives Performance awards in 2025 for their light system impact, while Bitdefender did not receive such recognition. Pricing strategies include significant renewal increases after steep first-year discounts. Customer support varies, with Norton and McAfee providing extensive 24/7 support, while Bitdefender offers limited phone support. The ownership structures differ, with Norton under Gen Digital, McAfee as a private entity, and Bitdefender remaining independent. Real-world scenarios suggest Bitdefender is best for single users, Norton 360 or McAfee+ for families, McAfee+ Ultimate or Norton for identity theft concerns, and Norton 360 for privacy-focused users.

Active Exploitation of Critical CVE-2026-20253 in Splunk Enterprise: Unauthenticated RCE via PostgreSQL Sidecar Service

A critical security vulnerability, SVD-2026-0603 (CVE-2026-20253), has been identified in Splunk Enterprise versions 10.0.0 through 10.0.6 and 10.2.0 through 10.2.3. This flaw allows unauthenticated, remote attackers to create or truncate arbitrary files on the host system by exploiting the PostgreSQL Sidecar Service endpoints. The vulnerability is actively exploited, with public proof-of-concept code available, and has been added to the CISA Known Exploited Vulnerabilities (KEV) list. Successful exploitation can lead to full remote code execution (RCE) as the Splunk user. The vulnerability arises from inadequate authentication controls on the PostgreSQL Sidecar Service endpoints, specifically /v1/postgres/recovery/backup and /v1/postgres/recovery/restore, which are accessible without authentication. It is classified under CWE-306: Missing Authentication for Critical Function and has a CVSS v3.1 base score of 9.8 (Critical). Attackers can exploit the vulnerability by sending crafted HTTP POST requests to the exposed endpoints, allowing them to create or truncate files and potentially execute malicious scripts. Indicators of compromise include unexpected files in directories such as /tmp/ or /opt/splunk/var/run/supervisor/pkg-run/, modified Splunk Python scripts, and unusual outbound connections from Splunk to unknown PostgreSQL servers. The vulnerability aligns with several MITRE ATT&CK techniques, including T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter). Active exploitation of CVE-2026-20253 has been confirmed, and it is likely that both opportunistic cybercriminals and sophisticated threat actors will use this exploit. The affected versions of Splunk Enterprise are 10.2.0 through 10.2.3 and 10.0.0 through 10.0.6, with the issue resolved in versions 10.2.4 and 10.0.7. Organizations are advised to upgrade to fixed versions or disable the PostgreSQL Sidecar Service as a mitigation strategy.

NCSC warns of messaging app targeting | National Cyber Security Centre

The National Cyber Security Centre (NCSC) has issued guidelines for individuals vulnerable to targeted attacks via messaging applications, particularly due to increased malicious activities from actors based in Russia. High-risk individuals, such as those with access to sensitive information, are especially susceptible. Past incidents involve state-affiliated groups like APT31 from China, the Russian FSB actor Star Blizzard, and Iran's IRGC targeting government officials. Attackers may use deceptive methods to obtain login codes, add devices to accounts, infiltrate group chats, impersonate contacts, and execute phishing attempts. To mitigate risks, individuals should avoid sharing sensitive information via messaging apps, use corporate services for work-related communications, refrain from sharing verification codes, activate two-step verification, utilize passkeys, regularly review linked devices, stay alert for impersonations, and consider using disappearing messages. The NCSC also provides guidance for enhancing account and device security for high-risk individuals.

Russian hackers hijack thousands of ‘high intelligence’ messaging app accounts, FBI warns

Hackers linked to Russian intelligence are targeting high-profile users of popular messaging applications, according to a warning from the FBI and CISA. The primary targets include U.S. government officials, military personnel, political figures, and journalists. The attackers compromise accounts to access messages and contact lists, allowing for further phishing attempts. Signal users are particularly at risk, though techniques can extend to WhatsApp and Telegram. The hackers use social engineering tactics, impersonating official support accounts to trick users into revealing sensitive information. The FBI and CISA advise users to be cautious of unexpected messages and suspicious links. Victims are encouraged to report incidents to the Internet Crime Complaint Center (IC3).

MyDoom virus: What it is and why it mattered

In January 2004, the MyDoom computer worm quickly spread to email inboxes in 168 countries, becoming one of the fastest-spreading pieces of malware in internet history. It exploited human behavior by enticing users to open email attachments that appeared to be delivery errors or system notifications. MyDoom replicated itself through email without corrupting files or destroying data, harvesting email addresses from infected computers to send copies to new victims. The two main variants, MyDoom.A and MyDoom.B, targeted the SCO Group and Microsoft, respectively, and demonstrated the potential for email worms to be weaponized for coordinated attacks. MyDoom primarily targeted Windows-based operating systems and used deceptive emails to propagate. Once infected, it installed a backdoor for unauthorized remote access, forming a botnet for further attacks. MyDoom's effectiveness was due to its alignment with user behavior and the limited security measures of the time, leading to significant disruptions in email communication and an estimated economic impact of approximately billion. Although no longer a current threat, MyDoom's legacy influenced modern email security protocols, leading to improved filtering, behavior-based detection, and multi-layered defense strategies.
