Windows ユーザーは注意:別のランサムウェアの嵐がやってくる

タイトルの内容に対する簡単な回答を以下のグラフに示します:

マルウェアの脅威、特にランサムウェアが絶え間なく存在するインターネットは、依然として危険な場所です。 AV Test による最近のレポートによると、9 億個のマルウェアが検出されました。これは、マルウェア業界がレドモンドのオペレーティング システム (つまり、知らない人には Windows) が照準を合わせ続けていることを証明しています。

AV テストとは

AV テスト GmbH は、ドイツを拠点とする独立した研究機関です。さまざまな基準に基づく研究機関は、Microsoft Windows および Android オペレーティング システム用のウイルス対策およびセキュリティ スイート ソフトウェアを定期的に評価および評価しています。そして、テスト結果を公開して、ユーザーが適切な製品を選択できるようにします。さらに、この研究所は業界、企業、政府に IT セキュリティの問題について助言し、偏りのない包括的な結果を保証する社内分析システムを使用しています。

AV-Test は何を発見しましたか?

「攻撃者は 6 兆ドルを標的にしているため、新しい企業は 11 秒ごとにランサムウェア攻撃の犠牲になります

この 2020 年」

最新のレポートで、AV-Test はマルウェア攻撃の増加率を示しています。前年と比較して、今回の新しいマルウェアの数は、1 日あたり 1 秒あたり 4.4 サンプルに増加しました。このマルウェアの開発率を見ると、この傾向は今後も拡大し、Windows がターゲットになると思われます。

新しいマルウェアの数が急増したのはなぜですか?

保護プログラムによる防御性能が継続的に向上するにつれて、サイバー犯罪者は、新しいマルウェア コードをより高速に起動する必要性を感じました。このために、彼らは好みの選択肢、つまりトロイの木馬を展開しました。

これは驚くべきことではありません。トロイの木馬は、機能と配布機会の両方の点で、別の種類のマルウェアに勝るものはありません.

Last year, these universal tools were added to nearly 2/3 of all malware programs developed for Windows (62.51%).

Does this mean macOS is secure?

No, the rate of malware developments almost tripled for Apple’s macOS also. In terms of percentage, the share of Mac malware increased to approximately 4%.

An average of 7,913 new malware samples per month for Apple’s operating system has been discovered by AV-TEST Institute.

This new breed of malware not only targets Windows and macOS. IoT devices to are at risk.

How unsafe are IoT devices

Basically, IoT devices and services to a large degree are unsafe. Here instead of the device users are the main target. Since apps to connect IoT devices usually run on mobile phones attackers use transmission paths and other recorded data for digital attacks.

With inadequate IT security IoT devices are at great risk and as their number increases a flood of malware is already waiting.

Mirai, a malware sample known for years, accounted for more than 40 percent of the total malicious code for IoT devices. Unfortunately, no steps have been taken to secure IoT devices and criminals continue to deploy Mirai successfully.

What is Ransomware?

Ransomware doesn’t only target large companies; anyone, including you, can be its victim. It is a form of malware designed to encrypt files. Once the attack is successful, the attacker demands a ransom to restore access to the data.

The most common vector used to take access to a computer is phishing emails. Once these emails are opened they take over victim computers, for this, they even design social engineering tools that trick users into allowing administrative access.

Anything of value that is smart and connected can be compromised and held for ransom,” said Steve Grobman, the chief technology officer at McAfee.

How does AV-Test work

The experts at AV –TEST  examine real-time detection done by security apps for the latest malware. Moreover, they measure the detection effectiveness to give a clear view of protection capabilities and what best can be done.

Windows remain under fire

Due to the security vulnerabilities, Windows system remains in the crosshair of the malware industry. When a cybercriminal plans a large-scale malware attack it is advised to plant malware in the Redmonds vulnerable OS. This consistently makes the operating system from Redmond the most heavily attacked software platform.

All this data and findings make clear Windows is the weakest link and with time things are going to get worse. Therefore, we need to take steps to stay secure from ransomware attacks.

How to Prevent Ransomware

There are a number of defensive steps you can take to stay protected from ransomware. These steps are good security practices, following them will only improve your defense.

• Avoid opening suspicious emails or downloading attachments.
• Keep your operating system patched with the latest updates.
• Don’t install software from unknown sources or give it administrative privileges unless you know about it
• Install good antivirus software or can use a cloud backup tool like

  to keep your important data safe.

• Never use unfamiliar USBs; you can even use USB Blocker program to stay protected.
• Are you using public Wi-Fi? Yes, use a VPN (Virtual Private Network) to protect yourself. The best VPN provides you with an encrypted communications tunnel and protects you from attack.

Stopping such attacks is difficult, but not impossible. By taking these precautionary measures you can stay one step ahead of criminals. IT literacy – such as knowing what to do and not is important it helps prevent the spread.
