Meet Linda Yaccarinon, Newly Appointed CEO of Twitter

Linda Yaccarino, the newly appointed CEO of Twitter was previously NBC Universal’s top advertising sales executive, she was on Friday officially announced as the new CEO of Twitter by Elon Musk.
Musk, who acquired Twitter last fall, tweeted his excitement about Yaccarino joining the company and mentioned that she would primarily focus on business operations while he concentrates on product design and new technology. The goal is to transform the platform into an all-encompassing app called “X, the everything app.”
Yaccarino is expected to assume her role at Twitter by the end of June. Musk, on the other hand, will take on the positions of executive chair and CTO. His acquisition of Twitter was a result of a contentious back-and-forth with the board.
One of Yaccarino’s primary responsibilities will be to rebuild Twitter’s advertising business, which Musk claimed had suffered a significant decline of up to 50% after he acquired the company.
Advertisers have been cautious due to Musk’s unpredictable decisions in running Twitter and his reinstatement of previously banned accounts.
Yaccarino is known to hold conservative political views and had served on Donald Trump’s council on sports and nutrition during his presidency.
However, her imminent appointment as Twitter CEO caused a stir on “conspiracy Twitter” as right-wing users discovered her affiliation with the World Economic Forum (WEF), an organization they perceive negatively. Yaccarino had chaired the WEF’s Taskforce on the Future of Work.
After announcing Yaccarino’s hire, Musk commented that he believes people from both ends of the political spectrum will find her to be smart, fair, and reasonable.
This announcement followed Musk’s previous day’s announcement about hiring a new CEO without disclosing her name. Reports soon revealed that Yaccarino, NBCU’s chairman of global advertising and partnerships, was in talks for the Twitter CEO position. On Friday, prior to Musk’s confirmation, Yaccarino resigned from NBCU.
Musk had previously stated his intention to step aside as Twitter’s chief executive once he found a suitable replacement. However, he will retain full control of the social network and remain closely involved in its management.
Although Musk’s deal for Twitter was initially valued at $44 billion, he now values the company at $20 billion. He has recently renamed the company “X Corp.” as the parent organization of Twitter.
Yaccarino’s interest in Twitter stems from recognizing the opportunities within the platform. Lou Paskalis, a former senior marketing executive at Bank of America, mentioned that Twitter is likely selling advertising at significant discounts in exchange for volume commitments.
Before her tenure at NBCU, Yaccarino spent 20 years in ad sales and marketing roles at Turner, holding positions such as EVP/COO of advertising sales, marketing, and acquisitions.

Minister Claims Bandits Exploit Poor Network, Bounce Calls Off Multiple Towers

Bosun Tijani, minister of Communications, Innovation and Digital Economy, yesterday claimed that bandits and terrorists are able to communicate and coordinate their activities with ease because they exploit gaps in the country’s telecommunications network.

Bosun Tijani, minister of Communications, Innovation and Digital Economy,
Tijani, who spoke Politics Today, a Channels Television’s programme, on Friday, Tijani said the criminals exploit gaps in the country’s telecommunications network.
He also claimed the bandits use advanced technology to bounce calls across multiple towers in areas with poor connectivity.
“They weren’t using the normal towers; they bounced calls off multiple towers, which is why they favor areas that are largely unconnected,” he said.
When asked about reports that unregistered or fraudulently registered SIM cards are still in use despite the Bank Verification Number (BVN) and the National Identification Number (NIN)–Subscriber Identity Module linkage policies, Tijani said the issue is technically complex and the reports are not fully verified.
“Whether it’s fact or not, I do not know where you’re getting that from, and I do not know who has evidence that there are people with unregistered SIMs,” he added.
The minister stated that the federal government is investing in telecom towers in underserved regions, upgrading the country’s communication satellites to improve coverage, and expanding fiber-optic networks to strengthen the country’s digital infrastructure.
“If our towers are not working, our satellites will work. Nigeria is the only country in West Africa with communication satellites, and we are bringing new satellites to upgrade their capabilities,” Tijani said.
He added that these initiatives aim to ensure better connectivity for Nigerians while closing loopholes that criminals exploit, thereby enhancing national security.
The minister’s comments come amid rising concerns over insecurity in several parts of the North, where banditry, kidnapping, and terrorism have escalated in recent years.
There are also reports of bandits flaunting ransom payments on social media platforms such as TikTok, raising alarm among authorities and the public

Sophos XDR Achieves its Best-Ever Results in the MITRE ATT&CK Enterprise 2025 Evaluation

Sophos, a global leader of innovative security solutions for defeating cyberattacks, has announced its best-ever results in the MITRE ATT&CK Enterprise 2025 Evaluation.

MITRE ATT&CK Enterprise 2025 Evaluation
Sophos XDR detected 100% of adversary behaviors (sub-steps)1 across two complex attack scenarios: Scattered Spider, which Sophos X-Ops tracks as GOLD HARVEST, a financially motivated cybercriminal collective, and Mustang Panda, which Sophos X-Ops tracks as BRONZE PRESIDENT, a People’s Republic of China (PRC) espionage group.
The Scattered Spider scenario included activity across Windows, Linux, and AWS cloud environments, and the Mustang Panda scenario focused on Windows only.
Further, Sophos achieved the highest-possible “Technique”-level rating for 86 out of 90 total sub-steps in the evaluation, by generating high-fidelity detections with details on execution, impact, and adversary behavior, providing clear who, what, when, where, how, and why insights.
Sophos XDR achieved:
- 100% detection coverage1 for all 90 adversary sub-steps across two complex attack scenarios across Windows, Linux, and AWS cloud environments
- Highest possible (“Technique”) ratings for 86 of 90 sub-steps, demonstrating deep visibility and actionable detections
- Highest possible (“Technique”) ratings for 61 out of 62 of sub-steps in the Scattered Spider scenario involving identity abuse, cloud exploitation, and data exfiltration
“Scattered Spider and Mustang Panda represent distinct threat profiles that challenge defenders in very different ways,” said Simon Reed, chief research and scientific officer, Sophos. “Achieving full detection coverage against both validates the accuracy and depth of Sophos’ analytics and demonstrates how the company’s AI-native XDR platform converts complex telemetry into clear, actionable intelligence, helping security teams detect, understand, and stop advanced attacks with confidence.
“Sophos’ consistently strong performance in these rigorous evaluations underscores the power and precision of our threat detection and response capabilities, and our commitment to stopping the world’s most sophisticated cyberthreats.
“Over the five years that Sophos has participated in ATT&CK Evaluations, we have continually invested in strengthening our platform, and that investment has translated into stronger results year after year – both in the evaluations, and in the security outcomes we deliver for our customers.”
These results demonstrate the power of the Sophos XDR platform to defend against sophisticated cyber threats. Every day, Sophos processes 223+ terabytes of telemetry in Sophos Central, generating 34+ million detections and automatically blocking 11+ million threats.
This scale of customer insights ensures that Sophos’ detections are being tested and improved to provide continuous protection while delivering stronger outcomes for organizations worldwide.
Understanding The Threat Actors
Sophos X-Ops has tracked GOLD HARVEST (Scattered Spider) since 2022, observing a loosely affiliated cybercriminal collective driven by both financial motives and a desire to elevate their reputations on underground forums.
Despite several arrests, operators and associates continue to launch high-profile attacks across the U.K. and U.S., at times partnering with major Russian-speaking ransomware groups.
Their sophisticated social engineering capabilities enable them to compromise even well-defended organizations, underscoring the importance of strong behavioral detections within modern security operations.
In parallel, Sophos X-Ops has monitored BRONZE PRESIDENT (Mustang Panda) for many years.
This long-running PRC espionage group conducts intelligence-led operations that align closely with priorities of China’s Ministry of State Security. Recent targeting includes activity against Tibetan communities surrounding the Dalai Lama’s 90th birthday, as well as intrusions on Thai government and military offices during periods of heightened regional tension.
BRONZE PRESIDENT remains one of the most active and persistent state-aligned threat actors operating today.
MITRE ATT&CK Evaluations are among the world’s most rigorous independent security tests.
They emulate the tactics, techniques, and procedures (TTPs) used by real-world adversaries to assess each participating vendor’s ability to detect, analyze, and articulate threats in alignment with the MITRE ATT&CK Framework.
These evaluations continually strengthen Sophos’ capabilities for the benefit of the organizations it protects. This was the seventh round of MITRE’s “Enterprise” ATT&CK Evaluation, a product-focused assessment designed to help organizations better understand how security operations solutions like Sophos EDR and Sophos XDR can help them defend against sophisticated, multi-stage attacks.
When evaluating EDR or XDR solutions, Sophos recommends reviewing MITRE ATT&CK Evaluations alongside other independent proof points.

CBN, NCC to Launch Short Code for Swift Consumer Complaint Resolution

Central Bank of Nigeria (CBN) on Thursday announced plans to partner with the Nigerian Communications Commission (NCC) to develop an industry-wide short code for consumers to lodge complaints with financial institutions anytime, anywhere, even without internet access.

CBN
Dr Aisha Isa-Olatinwo, CBN Director, Consumer Protection and Financial Inclusion Department, disclosed this at a virtual Consumer Protection Town Hall meeting titled “Ask the Regulator”, organised by Enhancing Financial Inclusion and Advancement (EFInA).
She said the initiative addresses challenges faced by vulnerable consumers using feature phones who often have to visit bank branches physically to report issues amid the convergence of telecom and banking services.
Isa-Olatinwo said the CBN had achieved 94 per cent month-on-month timely resolution of consumer complaints, adding that the apex bank had streamlined processes and partnered with banks to balance consumer protection with financial system stability.
An EFInA poll presented at the event revealed that 61 per cent of respondents experienced failed transactions in the past 12 months, while 26 per cent had reversals within 24 hours and 54 per cent between 24 and 48 hours.
Other complaints included six per cent for fraud, 14 per cent for hidden charges and 15 per cent for poor customer service, with 66 per cent of respondents aware of complaint escalation steps.
President of Consumer Advocacy Foundation of Nigeria (CAFON), Mrs Sola Salako-Ajulo, lamented that consumers often feel unprotected and urged introduction of fraud insurance for instant reversals, shifting the burden of proof from customers.
She said: “What is missing in our system—unlike more developed economies—is fraud insurance, where banks reverse reported fraud immediately, refund consumers, and investigate later.”
Mr Ajibade Laolu-Adewale, Chairman of Committee of e-Business Industry Heads (CeBIH), represented by Mr Adeyemi Salisu, stressed that banks must resolve disputes between acquiring and issuing banks without redirecting customers to merchants.
The short code initiative is expected to enhance financial inclusion by providing accessible redress mechanisms in Nigeria’s evolving digital payment ecosystem.
